FCE17B25SB4EB D-Sub 25 Position Receptacle Equivalent & Substitute Parts

Part Overview

The FCE17B25SB4EB is a 25 position D-Sub receptacle connector manufactured by Amphenol ICC (Commercial Products). This right-angle, through-hole solder termination connector features female sockets in a 2-row configuration with Shell Size 3 (DB, B) layout. The connector is currently in active product status with 1125 units in stock.

Equivalent and substitute parts are necessary when the primary part becomes unavailable, when alternative sourcing is required for supply chain optimization, or when design flexibility permits selection from multiple qualified manufacturers. Substitute connectors must maintain electrical and mechanical compatibility within the D-Sub 25 position receptacle category while meeting the same functional requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the FCE17B25SB4EB is based on the following critical parameters that must align across all equivalent parts:

Mandatory Matching Parameters:

• Connector Type: Receptacle, Female Sockets
• Number of Positions: 25
• Number of Rows: 2
• Shell Size, Connector Layout: 3 (DB, B)
• Mounting Type: Through Hole, Right Angle
• Termination: Solder
• Material Flammability Rating: UL94 V-0

Allowable Variation Parameters:

• Current Rating: 5A or higher
• Shell Material Finish: Steel with Tin Plated, Tin-Nickel Plated, or Nickel Plated finishes
• Contact Finish: Gold (Flash or 15.0µin thickness acceptable)
• Operating Temperature: Range must encompass or exceed -40°C ~ 85°C
• Backset Spacing: Minor variations within connector design tolerances
• Flange Feature: Board Side, Housing/Shell, or Mating Side configurations
• RoHS Status: RoHS Compliant or ROHS3 Compliant acceptable; RoHS non-compliant parts noted as restricted

The following parts meet substitution criteria for the FCE17B25SB4EB: 182-025-213R531, D25S13A4GX00LF, D25S13A4GV00LF, 5745440-1, and 5745440-4. Part 745440-1 is listed as obsolete and RoHS non-compliant, restricting its use in new designs.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Status, Full Compliance):

The parts D25S13A4GX00LF and D25S13A4GV00LF from Amphenol ICC (FCI) Delta D series are direct functional equivalents. Both are RoHS Compliant, active products with extended operating temperature ranges (-55°C ~ 125°C) and higher voltage ratings (300V). These parts provide superior performance margins over the FCE17B25SB4EB while maintaining identical mechanical and electrical interface compatibility.

The 5745440-1 and 5745440-4 from TE Connectivity AMP Connectors (AMPLIMITE HDP-20 series) are active, RoHS Compliant alternatives with 6A current ratings and 125V voltage specifications. Both parts exceed the thermal operating range of the primary part and are suitable for applications requiring higher current capacity.

Secondary Substitute (Active Status, Compliance Variation):

The 182-025-213R531 from NorComp Inc. is an active product with ROHS3 Compliance. This part offers equivalent electrical performance with an extended operating temperature range (-55°C ~ 105°C). The nickel-plated steel shell finish differs from the tin-plated finish of the primary part but remains within acceptable D-Sub connector specifications.

Restricted Substitute (Obsolete Status, Non-Compliance):

The 745440-1 from TE Connectivity AMP Connectors is marked as obsolete and RoHS non-compliant. This part is not recommended for new designs or applications requiring regulatory compliance with RoHS directives. Use of this part is restricted to legacy system maintenance only.

Frequently Asked Questions (FAQ)

Q: Can D25S13A4GX00LF be used as a direct replacement for FCE17B25SB4EB?

A: Yes. Both connectors share identical mechanical and electrical interface specifications: 25 position receptacle, female sockets, 2-row configuration, Shell Size 3 (DB, B), through-hole right-angle solder termination, and UL94 V-0 flammability rating. The D25S13A4GX00LF provides enhanced performance with extended operating temperature range and higher voltage rating.

Q: What is the difference between 5745440-1 and 5745440-4?

A: Both parts are from the TE Connectivity AMPLIMITE HDP-20 series with identical electrical and mechanical specifications. The primary difference is contact finish thickness specification: 5745440-1 specifies Flash gold finish, while 5745440-4 does not specify finish thickness. Both are functionally equivalent for the FCE17B25SB4EB application.

Q: Why is 745440-1 listed as restricted?

A: The 745440-1 is marked as obsolete and RoHS non-compliant. Obsolete status indicates the manufacturer has discontinued production. RoHS non-compliance restricts use in applications subject to European Union Restriction of Hazardous Substances regulations. This part is suitable only for legacy system maintenance where regulatory compliance is not required.

Q: Are there differences in flange features between substitute parts?

A: Yes. The FCE17B25SB4EB features a board-side flange (4-40). Substitute parts vary: 182-025-213R531 uses housing/shell flange (4-40), D25S13A4GX00LF uses housing/shell flange (4-40), D25S13A4GV00LF uses mating-side female screwlock (4-40), and TE Connectivity parts use mating-side standard screws. All flange configurations are mechanically compatible with standard D-Sub mounting practices.

Q: What is the significance of backset spacing variations?

A: Backset spacing is the distance from the connector mating face to the solder tail termination point. The FCE17B25SB4EB specifies 0.405" (10.29mm). Substitute parts show variations: 182-025-213R531 at 0.318" (8.08mm), D25S13 series at 0.409" (10.40mm), and TE Connectivity parts at 0.454" (11.53mm). These variations reflect different connector designs but do not affect electrical compatibility. PCB layout must accommodate the specific backset spacing of the selected part.

Q: Can I use a 6A-rated connector in place of a 5A-rated connector?

A: Yes. The 5745440-1 and 5745440-4 with 6A ratings exceed the 5A requirement of the FCE17B25SB4EB. Higher current ratings provide additional safety margin and are acceptable substitutes. The application circuit must not exceed the lower of the two ratings (5A in this case).

Q: What is the difference between RoHS Compliant and ROHS3 Compliant?

A: RoHS Compliant indicates compliance with the original Restriction of Hazardous Substances Directive (2002/95/EC). ROHS3 Compliant indicates compliance with the recast directive (2011/65/EU), which includes additional restricted substances. Both certifications are acceptable for regulatory purposes; ROHS3 represents the current standard.

Q: Are all substitute parts available in the same packaging?

A: No. The FCE17B25SB4EB packaging is not specified. Substitute parts are available in Tray packaging (182-025-213R531, D25S13A4GX00LF, D25S13A4GV00LF, 5745440-1, 5745440-4) or unspecified packaging (745440-1). Packaging differences do not affect connector functionality but may impact procurement and inventory management.
