FCE17B25SC28B D-Sub 25 Position Receptacle Equivalent & Substitute Parts

Part Overview

The FCE17B25SC28B is a 25 position D-Sub receptacle connector manufactured by Amphenol ICC (Commercial Products). This connector features female sockets, right-angle solder termination, and is designed for through-hole mounting applications. The part is currently active in production with 734 units in stock.

D-Sub connectors of this configuration are widely used in industrial, telecommunications, and legacy computing applications where standardized 25-pin signal distribution is required. Equivalent and substitute parts become necessary when the primary manufacturer part is unavailable, when alternative sourcing is required for supply chain optimization, or when design requirements permit functional alternatives with different mechanical or electrical characteristics.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Highest Compatibility):

The TE Connectivity AMPLIMITE HD-20 series parts (5747838-4 and 747838-4) provide the closest functional equivalence to the FCE17B25SC28B. Both parts maintain identical mechanical interfaces, support higher current ratings (6A versus 5A), and feature extended operating temperature ranges (-55°C ~ 105°C). Part 5747838-4 carries RoHS Compliant certification, matching the regulatory status of the primary part. Part 747838-4 also maintains RoHS Compliance. Both include board lock and ground strap features, providing enhanced mechanical stability in production environments.

Secondary Substitutes (Acceptable with Compliance Verification):

The NorComp Inc. 183-025-213R571 maintains identical electrical specifications and current rating (5A) with ROHS3 Compliant certification. This part features panel mount capability in addition to through-hole mounting, offering design flexibility. The nickel-plated steel shell provides corrosion resistance equivalent to tin plating in standard industrial environments.

The TE Connectivity 5747838-3 and 747838-3 parts are functionally equivalent with 6A current ratings and extended temperature ranges. Part 5747838-3 carries RoHS Compliance. Both feature flash gold contact finish and board lock functionality.

Compliance Considerations:

Part 747838-3 is RoHS non-compliant and should be selected only in applications where RoHS compliance is not a regulatory requirement. All other substitute parts maintain RoHS Compliance or ROHS3 Compliance status, matching or exceeding the regulatory posture of the FCE17B25SC28B.

Flange Feature Variations:

Part 5747838-6 features a mating side female screwlock configuration, providing enhanced connector retention compared to standard housing/shell flanges. This variant is suitable for applications requiring positive mechanical locking at the mating interface.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 5747838-4 directly replace the FCE17B25SC28B in existing designs?

A: Yes. The 5747838-4 maintains identical mechanical interface dimensions, backset spacing (0.590"), shell size (3/DB/B), and solder termination configuration. The higher current rating (6A versus 5A) and extended operating temperature range (-55°C ~ 105°C versus -40°C ~ 85°C) provide enhanced performance margins. RoHS Compliance status is equivalent.

Q: What is the difference between the NorComp 183-025-213R571 and the Amphenol FCE17B25SC28B?

A: Both parts are functionally equivalent 25-position D-Sub receptacles with identical current ratings (5A) and backset spacing. The NorComp part features nickel-plated steel shell finish versus tin plating, and includes panel mount capability in addition to through-hole mounting. The NorComp part carries ROHS3 Compliant certification. Contact finish thickness is flash gold on the NorComp part versus 15.0µin on the Amphenol part.

Q: Are there packaging differences between substitute parts?

A: Yes. The FCE17B25SC28B is supplied without specified packaging. The NorComp 183-025-213R571 is packaged in trays. TE Connectivity parts (5747838 and 747838 series) are packaged in tubes. Packaging selection should be coordinated with procurement and assembly processes.

Q: Which substitute part has the widest operating temperature range?

A: All TE Connectivity substitute parts (5747838-3, 5747838-4, 5747838-6, 747838-3, 747838-4) and the NorComp 183-025-213R571 operate across -55°C ~ 105°C, exceeding the FCE17B25SC28B range of -40°C ~ 85°C. The NorComp part also supports this extended range.

Q: What is the significance of the board lock feature on TE Connectivity parts?

A: The board lock feature provides mechanical retention of the connector to the printed circuit board during assembly and operation, reducing stress on solder joints and improving reliability in vibration-prone environments. This feature is present on all TE Connectivity substitute parts but not specified on the FCE17B25SC28B.

Q: Can I use part 747838-3 in a new design requiring RoHS compliance?

A: No. Part 747838-3 is RoHS non-compliant. For RoHS-compliant applications, select from: FCE17B25SC28B (Amphenol), 183-025-213R571 (NorComp), 5747838-3, 5747838-4, 5747838-6, or 747838-4 (TE Connectivity).

Q: What is the difference between 5747838-6 and other TE Connectivity substitutes?

A: Part 5747838-6 features a mating side female screwlock flange configuration, providing positive mechanical locking at the connector interface. Other TE Connectivity parts feature standard housing/shell flanges with 4-40 threading. The screwlock variant is suitable for applications requiring enhanced connector retention during mating and unmating cycles.

Q: Are all substitute parts rated for 5A current?

A: No. The FCE17B25SC28B and NorComp 183-025-213R571 are rated for 5A. All TE Connectivity substitute parts (5747838 and 747838 series) are rated for 6A, providing higher current capacity.
