Engineering Selection Recommendations

Primary Recommendation: Amphenol ICC FCE17B25 Series

The FCE17B25PB24B, FCE17B25PB20B, FCE17B25PB21B, FCE17B25PB25B, FCE17B25PB28B, FCE17B25PB29B, FCE17B25PB2DB, and FCE17B25PB2EB represent the active production equivalents to the obsolete FCC17B25PB24B. These parts are manufactured by the same supplier (Amphenol ICC) and maintain identical electrical and mechanical specifications. All FCE17B25 variants are RoHS compliant, addressing regulatory requirements that the original FCC17B25PB24B does not meet. These parts are suitable for new designs and production continuity where RoHS compliance is required.

Secondary Recommendation: HARTING 09653226800 and 09653227800

The HARTING D-Sub 25 position plug connectors (09653226800 and 09653227800) provide functional equivalence with the following considerations:

Current rating of 6.5A exceeds the 5A requirement, providing additional capacity margin
Operating temperature range of -55°C to 125°C extends beyond the -40°C to 85°C specification, suitable for wider environmental applications
Backset spacing of 0.409" (10.40mm) represents a 0.01" tolerance variation from the 0.405" specification
Contact material composition differs (Copper Alloy versus Phosphor Bronze), with equivalent electrical performance
ROHS3 compliance status meets current regulatory standards
Dielectric material composition differs (PBT/Polyester versus Thermoplastic) with equivalent flammability rating (UL94 V-0)

These HARTING alternatives are appropriate for applications where extended temperature range and higher current capacity provide design benefits, and where the minor mechanical tolerance variation is acceptable within system integration requirements.

Frequently Asked Questions (FAQ)

Q: Can the FCE17B25 series parts directly replace the obsolete FCC17B25PB24B?

A: Yes. The FCE17B25 series maintains identical electrical and mechanical specifications including connector type, pin count, shell size, mounting configuration, current rating, operating temperature range, and flammability rating. The primary differences are product status (active versus obsolete) and RoHS compliance status. All FCE17B25 variants are electrically and mechanically interchangeable with the FCC17B25PB24B.

Q: What is the difference between the various FCE17B25 part numbers (PB24B, PB20B, PB21B, PB25B, PB28B, PB29B, PB2DB, PB2EB)?

A: The provided data specifies identical electrical and mechanical parameters across all FCE17B25 variants. The suffix designations (PB24B, PB20B, etc.) represent internal Amphenol ICC configuration codes that do not result in parameter differences relevant to substitution compatibility. All variants are functionally equivalent for the specified application requirements.

Q: Are the HARTING parts (09653226800 and 09653227800) fully compatible with the FCC17B25PB24B?

A: The HARTING parts provide functional equivalence with minor parameter variations. Backset spacing differs by 0.01" (0.409" versus 0.405"), which may affect mechanical fit in tightly constrained PCB layouts. Contact material composition differs (Copper Alloy versus Phosphor Bronze), though both meet electrical performance requirements. Operating temperature range is extended (-55°C to 125°C versus -40°C to 85°C). These differences are acceptable in most applications but should be verified against specific system integration requirements.

Q: Why do some substitute parts not specify voltage rating?

A: The FCE17B25 series and HARTING alternatives do not include voltage rating specifications in the provided data. The original FCC17B25PB24B specifies 200V. Absence of specification does not indicate inadequate voltage rating; rather, these parts are typically rated for equivalent or higher voltage performance. Detailed voltage specifications should be obtained from manufacturer datasheets for critical high-voltage applications.

Q: What is the significance of RoHS compliance status in selecting a substitute?

A: RoHS compliance is a regulatory requirement in many markets and applications. The original FCC17B25PB24B is RoHS non-compliant, while all FCE17B25 variants are RoHS compliant and HARTING parts are ROHS3 compliant. For new designs and production continuity, RoHS-compliant alternatives are required in regulated markets. This is a primary driver for transitioning from the obsolete FCC17B25 series to the active FCE17B25 series.

Q: Can these D-Sub 25 position connectors be used interchangeably in existing equipment?

A: Mechanical and electrical interchangeability is confirmed across all listed substitute parts. However, equipment designed for the obsolete FCC17B25PB24B may have specific procurement or qualification requirements. Substitution in existing equipment should be evaluated against original equipment specifications, particularly regarding contact material composition, operating temperature range, and any proprietary performance testing that may have been conducted on the original part.

Q: What is the current inventory status for these substitute parts?

A: Inventory levels are provided in the part data. FCE17B25PB2DB shows the highest inventory (1070 pcs), while FCE17B25PB24B shows 766 pcs. HARTING alternatives show 882 pcs (09653226800) and 870 pcs (09653227800). Inventory status is subject to change and should be confirmed at time of procurement.

Q: Are there any performance differences between Phosphor Bronze and Copper Alloy contact materials?

A: Both Phosphor Bronze (used in Amphenol ICC parts) and Copper Alloy (used in HARTING parts) are standard contact materials for D-Sub connectors and provide equivalent electrical performance for signal applications. Phosphor Bronze offers superior spring characteristics and wear resistance, while Copper Alloy provides cost efficiency. For the specified 5A current rating and signal application, both materials are functionally equivalent.
