FCE17B25SC6DB D-Sub 25 Position Receptacle Equivalent & Substitute Parts

Part Overview

The FCE17B25SC6DB 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 designed for signal applications with a 5A current rating and operates across the temperature range of -40°C to 85°C. The part is currently active in production and RoHS compliant.

Equivalent and substitute parts are necessary when the primary part becomes unavailable, when alternative manufacturers are required for supply chain diversification, or when design specifications allow for compatible alternatives that meet the same electrical and mechanical requirements.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Highest Compatibility):

The TE Connectivity AMPLIMITE HD-20 series parts (5747838-3, 5747838-4, 5747838-6, 747838-3, and 747838-4) are direct functional equivalents. All five variants maintain the core D-Sub 25 position receptacle configuration with identical mechanical and electrical parameters. These parts offer enhanced current ratings (6A versus 5A) and extended operating temperature ranges (-55°C to 105°C versus -40°C to 85°C), providing superior performance margins. All TE Connectivity variants include board lock and ground strap features. The 5747838 series variants are RoHS compliant, while 747838-3 is non-compliant; 747838-4 is RoHS compliant.

Secondary Substitute (Alternative Manufacturer):

The NorComp 183-025-213R571 provides an alternative from a different manufacturer. This part maintains identical electrical specifications and mechanical compatibility. The NorComp variant features nickel plating on the steel shell (versus tin plating on the primary part) and includes panel mount capability in addition to through-hole mounting. The operating temperature range extends to -55°C to 105°C. This part is ROHS3 compliant and REACH unaffected.

Compliance Considerations:

For applications requiring RoHS compliance, select from: FCE17B25SC6DB (Amphenol ICC), 183-025-213R571 (NorComp), 5747838-3, 5747838-4, 5747838-6, or 747838-4 (TE Connectivity). The part 747838-3 is RoHS non-compliant and should be selected only when RoHS compliance is not a requirement.

Flange Feature Differentiation:

The 5747838-6 variant features a mating side female screwlock (4-40) flange, distinguishing it from other variants which use housing/shell (4-40) or board side (M3) flanges. Selection should be based on specific mechanical mounting requirements.

Frequently Asked Questions (FAQ)

Q: Can the FCE17B25SC6DB be directly replaced with any of the listed substitute parts?

A: All listed substitute parts are mechanically and electrically compatible with the FCE17B25SC6DB. Direct replacement is possible without modification to the connector interface, PCB footprint, or mating connector. However, verify that the specific flange feature and mounting configuration match your application requirements.

Q: What is the difference between the TE Connectivity 5747838 and 747838 series?

A: Both series are AMPLIMITE HD-20 D-Sub 25 position receptacles with identical core specifications. The primary difference is RoHS compliance status: the 5747838 series is RoHS compliant, while 747838-3 is non-compliant (747838-4 is compliant). All variants share the same electrical and mechanical parameters.

Q: Why do some substitute parts have higher current ratings (6A) than the primary part (5A)?

A: The substitute parts are rated for higher current capacity, which does not prevent their use in applications designed for 5A operation. The higher rating indicates greater current handling capability and provides additional design margin. This is an allowable variation that does not compromise compatibility.

Q: Does the extended operating temperature range of substitute parts affect compatibility?

A: No. The extended operating temperature range (-55°C to 105°C on substitute parts versus -40°C to 85°C on the primary part) represents an enhancement. Applications operating within the original temperature specification remain fully compatible. The wider range provides additional operational flexibility without affecting performance within the original design envelope.

Q: What is the significance of contact finish thickness variations?

A: Contact finish thickness variations (15.0µin, Flash, or 30.0µin) do not affect electrical or mechanical compatibility. All variants maintain gold contact finish for signal integrity and corrosion resistance. Thickness differences reflect manufacturing process variations and do not impact connector performance within the specified electrical parameters.

Q: Is the NorComp 183-025-213R571 suitable as a substitute if panel mount capability is not needed?

A: Yes. The NorComp part includes panel mount as an additional feature but functions identically as a through-hole right-angle solder connector. The presence of panel mount capability does not interfere with standard through-hole PCB mounting applications.

Q: What packaging formats are available for these substitute parts?

A: The Amphenol ICC FCE17B25SC6DB is supplied in standard packaging. NorComp 183-025-213R571 is supplied in trays. TE Connectivity variants (5747838 and 747838 series) are supplied in tubes. Packaging format does not affect connector performance or compatibility; selection should be based on inventory management and handling requirements.

Q: Are all substitute parts currently in active production?

A: Yes. All listed substitute parts maintain active product status, ensuring ongoing availability and supply chain reliability. The primary part FCE17B25SC6DB is also active in production.
