Substitute Part Grouping Explanation

Substitution logic for the FCC17B25SA4DB is based on maintaining electrical and mechanical compatibility across the following critical parameters:

Critical Compatibility Parameters:

Connector style (D-Sub), type (receptacle with female sockets), position count (25), row configuration (2 rows), and shell size (3/DB/B) must remain identical
Mounting method (through-hole, right-angle) and termination type (solder) are non-negotiable for PCB integration
Contact type (signal) must be preserved

High-Priority Compatibility Parameters:

Flange feature variations (board side vs. housing/shell mounting) are acceptable provided the mounting hole pattern remains compatible with 4-40 or equivalent fastening specifications
Current rating must equal or exceed 5A; substitute parts rated at 6.5A are acceptable
Voltage rating of 200V is a design specification; substitute parts without specified voltage ratings do not contradict this requirement
Operating temperature range must encompass or exceed -40°C to 85°C; extended ranges (-55°C to 125°C) are acceptable
UL94 V-0 flammability rating must be maintained

Compliance Considerations:

RoHS compliance status differs between the main part (non-compliant) and active substitutes (RoHS3 compliant). Selection depends on end-application regulatory requirements
Moisture sensitivity level (MSL 1 - Unlimited) is consistent across all parts

Mechanical Variations Permitted:

Backset spacing differs between Amphenol ICC parts (0.318" / 8.08mm) and HARTING parts (0.409" / 10.40mm). This variation reflects different connector series designs and may affect PCB layout compatibility
Contact form (machined vs. stamped) and contact material (phosphor bronze vs. copper alloy) represent manufacturing process differences that do not affect electrical performance for signal applications
Shell material finish variations (tin plated vs. unspecified) are acceptable

Engineering Selection Recommendations

Primary Substitute: FCE17B25SA4DB (Amphenol ICC)

The FCE17B25SA4DB is the recommended primary substitute for the obsolete FCC17B25SA4DB. Both parts are manufactured by Amphenol ICC and share identical electrical and mechanical specifications: 25 position D-Sub receptacle, female sockets, through-hole right-angle solder termination, 5A current rating, 200V voltage rating, and -40°C to 85°C operating temperature range. The FCE17B25SA4DB is active in production with 944 units in stock. The primary difference is the flange feature configuration (housing/shell 4-40 vs. board side 4-40), which represents a minor mechanical variation that does not affect electrical performance. The FCE17B25SA4DB achieves RoHS compliance, whereas the original part is non-compliant. Selection of this substitute is appropriate for applications where RoHS compliance is required.

Secondary Substitutes: HARTING 09663126600, 09663126601, 09663126602, 09663127600, 09663127601, 09663127602, 09663526611, 09663526615, 09663526616

HARTING manufactures a series of 25 position D-Sub receptacles that maintain critical compatibility with the FCC17B25SA4DB across connector style, type, position count, row configuration, shell size, mounting type, and termination method. All HARTING substitutes are active products with ROHS3 compliance and extended operating temperature ranges (-55°C to 125°C), providing enhanced thermal performance. Current ratings are increased to 6.5A, exceeding the original 5A specification. Voltage ratings are not specified for HARTING parts; applications requiring explicit 200V voltage rating confirmation should reference manufacturer datasheets.

Unthreaded housing/shell: 09663126600, 09663127600
M3 threaded housing/shell: 09663126601, 09663127601, 09663526611, 09663526615
4-40 threaded housing/shell: 09663126602, 09663127602, 09663526616

Board Lock Feature: Parts 09663526611, 09663526615, and 09663526616 include a board lock feature not present in the original FCC17B25SA4DB. This feature provides mechanical retention enhancement and is compatible with applications requiring additional connector stability.

Backset Spacing Consideration: HARTING parts feature 0.409" (10.40mm) backset spacing compared to 0.318" (8.08mm) for Amphenol ICC parts. This dimensional difference may affect PCB layout compatibility and should be evaluated during design integration.

Compliance Selection Criteria:

For RoHS-compliant applications: FCE17B25SA4DB (Amphenol ICC) or any HARTING substitute
For applications requiring original RoHS non-compliant specification: FCC17B25SA4DB (if available from inventory)
For extended temperature range requirements: HARTING substitutes (-55°C to 125°C vs. -40°C to 85°C)

Frequently Asked Questions (FAQ)

Q: Can the FCE17B25SA4DB directly replace the FCC17B25SA4DB without PCB modification?

A: The FCE17B25SA4DB maintains identical electrical specifications and mounting type (through-hole, right-angle solder). The flange feature differs (housing/shell 4-40 vs. board side 4-40), which represents a mechanical mounting variation. Direct replacement is possible if the PCB mounting hole pattern accommodates the housing/shell flange configuration. PCB layout review is recommended to confirm mounting hole compatibility.

Q: What is the primary difference between Amphenol ICC and HARTING substitutes?

A: Amphenol ICC substitutes (FCE17B25SA4DB) maintain the original electrical specifications including 5A current rating and 200V voltage rating with -40°C to 85°C operating temperature. HARTING substitutes provide enhanced specifications: 6.5A current rating and extended -55°C to 125°C operating temperature range. HARTING parts feature different backset spacing (0.409" vs. 0.318"), which may require PCB layout adjustment. All HARTING substitutes are ROHS3 compliant.

Q: Does backset spacing difference affect connector functionality?

A: Backset spacing (0.318" for Amphenol ICC vs. 0.409" for HARTING) defines the distance from the PCB surface to the connector mating face. This dimensional difference does not affect electrical performance but may impact PCB layout compatibility, particularly in space-constrained applications. PCB design must accommodate the specific backset spacing of the selected substitute.

Q: Are HARTING substitutes with board lock features compatible with applications designed for the original FCC17B25SA4DB?

A: HARTING parts 09663526611, 09663526615, and 09663526616 include board lock features that provide mechanical retention enhancement. These features are additive and do not prevent compatibility with applications designed for the original part. The board lock feature provides additional connector stability and is compatible with standard mating connectors.

Q: Which substitute should be selected for RoHS-compliant applications?

A: The FCE17B25SA4DB (Amphenol ICC) and all HARTING substitutes (09663126600 through 09663526616) are RoHS compliant. The FCE17B25SA4DB is recommended for applications requiring minimal design changes, as it maintains identical electrical specifications and similar mechanical configuration to the original part. HARTING substitutes are appropriate for applications benefiting from enhanced current rating and extended operating temperature range.

Q: What is the significance of the different flange feature options in HARTING substitutes?

A: HARTING substitutes offer three flange feature configurations: unthreaded housing/shell, M3 threaded housing/shell, and 4-40 threaded housing/shell. The original FCC17B25SA4DB features board side 4-40 mounting. Selection should be based on PCB mounting hole specifications. The 4-40 threaded housing/shell variants (09663126602, 09663127602, 09663526616) provide closest mechanical compatibility with the original part's fastening specification.

Q: Can voltage rating be assumed for HARTING substitutes if not specified?

A: Voltage rating is not specified in the provided data for HARTING substitutes. Applications with explicit voltage rating requirements (such as 200V) should reference manufacturer datasheets or contact HARTING directly for voltage specification confirmation. The original FCC17B25SA4DB specifies 200V; HARTING substitutes are suitable for signal-level applications but voltage rating must be independently confirmed for high-voltage applications.

Q: Is contact material difference (phosphor bronze vs. copper alloy) significant for signal applications?

A: Contact material differs between Amphenol ICC parts (phosphor bronze) and HARTING parts (copper alloy). For signal-level applications, both materials provide adequate electrical conductivity and contact reliability. Contact material selection reflects manufacturing process differences and does not affect electrical performance for standard signal transmission. Material selection becomes significant only in specialized applications requiring specific contact resistance or corrosion resistance properties.

Q: What inventory availability should be considered when selecting a substitute?

A: Current inventory levels are: FCC17B25SA4DB (701 units, obsolete), FCE17B25SA4DB (944 units, active), HARTING 09663126600 (734 units), 09663126601 (1073 units), 09663126602 (1054 units), 09663127600 (791 units), 09663127601 (1127 units), 09663127602 (1004 units), 09663526611 (878 units), 09663526615 (911 units), 09663526616 (894 units). All substitutes maintain adequate inventory levels for procurement. Selection based on availability is not a limiting factor.
