Substitute Part Grouping Explanation

Substitution of the FCC17B25SA49B is determined by strict alignment of the following critical parameters:

Primary Compatibility Criteria:

Connector style (D-Sub)
Connector type (Receptacle, Female Sockets)
Number of positions (25)
Number of rows (2)
Shell size and layout (3 / DB, B)
Mounting type (Through Hole, Right Angle)
Termination method (Solder)
Contact type (Signal)
Material flammability rating (UL94 V-0)

Secondary Compatibility Considerations:

Current rating (5A minimum)
Voltage rating (200V minimum)
Operating temperature range (must encompass -40°C to 85°C)
Moisture sensitivity level (MSL 1)

Flange Feature Variations: Substitute parts may differ in flange feature design (Board Side vs. Housing/Shell, with varying mounting hole configurations: 4-40, M3, or Unthreaded). These variations do not affect electrical compatibility but impact mechanical mounting and board integration.

Contact Material and Finish Variations: Substitute parts from HARTING utilize stamped copper alloy contacts without specified finish thickness, compared to the machined phosphor bronze contacts with 15.0µin gold plating on the original part. These material differences do not preclude functional substitution for signal applications within the specified electrical parameters.

Backset Spacing Variation: HARTING substitute parts feature 0.409" (10.40mm) backset spacing compared to the original 0.318" (8.08mm). This dimensional difference affects board layout and mechanical fit but does not impact electrical performance.

Engineering Selection Recommendations

Primary Substitute: FCE17B25SA49B (Amphenol ICC)

The FCE17B25SA49B is the direct active equivalent from the same manufacturer. This part maintains identical electrical specifications (5A current rating, 200V voltage rating, -40°C to 85°C operating temperature) and mechanical configuration. The FCE17B25SA49B is RoHS Compliant, addressing regulatory requirements that the obsolete FCC17B25SA49B does not meet. This part is recommended as the first choice for direct replacement in new designs and legacy system updates.

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

All HARTING D-Sub 25 position receptacle models listed are functionally compatible with the FCC17B25SA49B for signal applications. These parts meet the core electrical and mechanical requirements: 25 position, 2 row, DB/B shell size, through-hole right-angle solder termination, and UL94 V-0 flammability rating. HARTING parts provide enhanced current capacity (6.5A vs. 5A) and extended operating temperature range (-55°C to 125°C vs. -40°C to 85°C), offering performance margins beyond the original specification.

All HARTING substitutes are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory standards.

Flange Feature Selection:

HARTING parts are available with three flange configurations:

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

Select the flange configuration matching your board mounting hole specifications. The original FCC17B25SA49B features a board-side 4-40 flange; HARTING 09663126602, 09663127602, and 09663526616 provide equivalent 4-40 mounting.

Board Lock Feature:

HARTING parts 09663526611, 09663526615, and 09663526616 include a board lock feature for enhanced mechanical retention. This feature does not affect electrical compatibility and may be beneficial for applications requiring additional vibration resistance.

Backset Spacing Consideration:

HARTING parts feature 0.409" (10.40mm) backset spacing compared to the original 0.318" (8.08mm). This dimensional difference requires board layout verification to ensure adequate clearance for the connector body and cable routing.

Frequently Asked Questions (FAQ)

Q: Can I directly replace FCC17B25SA49B with FCE17B25SA49B?

A: Yes. The FCE17B25SA49B is the active equivalent from Amphenol ICC with identical electrical and mechanical specifications. It is the recommended direct replacement for the obsolete FCC17B25SA49B.

Q: Are HARTING D-Sub 25 position receptacles electrically compatible with the FCC17B25SA49B?

A: Yes. All listed HARTING models (09663126600 series, 09663127600 series, and 09663526600 series) meet the core electrical requirements for signal applications: 25 positions, 2 rows, DB/B shell size, through-hole right-angle solder termination, and UL94 V-0 flammability rating. Current rating (6.5A) and operating temperature range (-55°C to 125°C) exceed the original specifications.

Q: What is the difference between HARTING flange options?

A: HARTING substitutes are available with three flange configurations: unthreaded housing/shell, M3 threaded housing/shell, and 4-40 threaded housing/shell. Selection depends on your board mounting hole design. For boards designed for 4-40 mounting, use HARTING 09663126602, 09663127602, or 09663526616.

Q: Does the backset spacing difference affect compatibility?

A: Backset spacing (the distance from the flange to the rear of the connector body) differs between the original part (0.318") and HARTING substitutes (0.409"). This affects board layout and cable routing clearance. Verify your board design accommodates the increased backset spacing before selecting HARTING substitutes.

Q: Are all substitute parts RoHS compliant?

A: The FCE17B25SA49B is RoHS Compliant. All HARTING substitutes are ROHS3 Compliant. The original FCC17B25SA49B is RoHS non-compliant. For applications requiring RoHS compliance, use FCE17B25SA49B or any HARTING substitute.

Q: What is the difference between stamped and machined contacts?

A: The original FCC17B25SA49B uses machined phosphor bronze contacts with 15.0µin gold plating. HARTING substitutes use stamped copper alloy contacts without specified finish thickness. For signal applications within the specified electrical parameters, both contact types provide functional compatibility. Machined contacts may offer superior durability in high-cycle mating applications.

Q: Can I use HARTING parts with board lock features as a direct replacement?

A: Yes. HARTING parts 09663526611, 09663526615, and 09663526616 include board lock features that do not affect electrical compatibility. These parts are functionally equivalent to non-board-lock variants and may provide enhanced mechanical retention for vibration-prone applications.

Q: What is the current rating difference, and does it matter?

A: The original FCC17B25SA49B is rated for 5A; HARTING substitutes are rated for 6.5A. For applications operating at or below 5A, the higher HARTING rating provides additional safety margin. For applications exceeding 5A but within 6.5A, HARTING substitutes enable operation within specification.

Q: Are there inventory considerations for these substitutes?

A: All listed substitute parts are in active production with substantial inventory availability (734 to 1127 pieces in stock across HARTING variants; 874 pieces for FCE17B25SA49B). The original FCC17B25SA49B, classified as obsolete, has limited remaining inventory (781 pieces).
