Engineering Selection Recommendations

Primary Substitutes (Amphenol ICC FCE17 Series):

The FCE17B25SC65B, FCE17B25SC60B, FCE17B25SC61B, FCE17B25SC64B, FCE17B25SC68B, FCE17B25SC69B, FCE17B25SC6DB, and FCE17B25SC6EB are direct functional equivalents of the FCC17B25SC65B. All FCE17 variants maintain identical mechanical specifications, electrical ratings, and connector geometry. The primary distinction is product status: all FCE17 parts are active, whereas the FCC17B25SC65B is obsolete. Additionally, all FCE17 variants are RoHS compliant, addressing regulatory requirements for new designs and manufacturing environments subject to RoHS directives.

The FCE17 series employs thermoplastic glass-filled dielectric material compared to the standard thermoplastic in the original part. This material enhancement provides improved mechanical and thermal stability while maintaining full electrical compatibility. All FCE17 variants share identical backset spacing (0.590"), current rating (5A), operating temperature range (-40°C to 85°C), contact finish (gold, 15.0µin), and flange configuration (board-side M3).

Secondary Substitutes (HARTING 09663126600 and 09663126601):

The HARTING 09663126600 and 09663126601 connectors provide alternative sourcing for 25-position D-Sub receptacles with through-hole, right-angle solder termination. These parts maintain core mechanical compatibility with identical shell size (3/DB/B), position count (25 in 2 rows), and mounting orientation. Both HARTING parts are RoHS3 compliant and feature UL94 V-0 flammability ratings.

Differences from the primary substitutes include: backset spacing of 0.409" (10.40mm) versus 0.590" (14.99mm) on the FCC17B25SC65B, higher current rating (6.5A versus 5A), extended operating temperature range (-55°C to 125°C versus -40°C to 85°C), and stamped contact form versus machined contacts. The HARTING 09663126601 features board-side M3 flange configuration matching the original part, while 09663126600 uses unthreaded housing/shell flange. These HARTING alternatives are suitable for applications where the different backset spacing and enhanced thermal performance are compatible with board layout requirements.

Frequently Asked Questions (FAQ)

Q: Can the FCE17B25SC65B directly replace the obsolete FCC17B25SC65B in existing designs?

A: Yes. The FCE17B25SC65B maintains identical mechanical dimensions, electrical ratings, connector geometry, and solder termination specifications. The part is a direct form-fit-function replacement. The primary differences are active product status and RoHS compliance, which are improvements for manufacturing and regulatory compliance.

Q: What is the significance of the glass-filled dielectric material in FCE17 variants?

A: The thermoplastic glass-filled dielectric in FCE17 parts provides enhanced mechanical strength and thermal stability compared to standard thermoplastic. This material change does not affect electrical performance or compatibility with mating connectors. It represents a material improvement that maintains full backward compatibility.

Q: Are all FCE17B25SC6xB variants electrically and mechanically interchangeable?

A: Yes. All FCE17B25SC60B, FCE17B25SC61B, FCE17B25SC64B, FCE17B25SC68B, FCE17B25SC69B, FCE17B25SC6DB, and FCE17B25SC6EB variants share identical specifications for position count, shell size, mounting type, termination method, flange configuration, current rating, operating temperature, contact finish, and backset spacing. The suffix designations reflect internal design variations that do not affect external compatibility.

Q: Why do the HARTING parts have different backset spacing?

A: The HARTING 09663126600 and 09663126601 connectors feature 0.409" (10.40mm) backset spacing compared to 0.590" (14.99mm) on the FCC17B25SC65B and FCE17 series. This dimensional difference reflects different connector design standards. Selection between Amphenol and HARTING alternatives depends on board layout requirements and available mounting space. The HARTING parts are suitable only if the reduced backset spacing is compatible with the application.

Q: What does the M3 flange feature indicate?

A: The M3 flange feature on the FCC17B25SC65B, FCE17 series, and HARTING 09663126601 indicates board-side mounting with M3 threaded holes for mechanical fastening. This provides secure board-level attachment. The HARTING 09663126600 uses unthreaded housing/shell flange, which does not include threaded mounting holes.

Q: Are there any compliance differences between the substitute parts?

A: The FCC17B25SC65B is RoHS non-compliant. All FCE17 variants and HARTING parts are RoHS compliant (RoHS or ROHS3). For applications subject to RoHS regulations or customer requirements, the compliant alternatives are mandatory. The HARTING parts additionally carry REACH Unaffected status.

Q: Can the HARTING 09663126600 be used where the HARTING 09663126601 is specified?

A: Both HARTING parts share identical electrical and mechanical specifications except for flange configuration. The 09663126600 features unthreaded housing/shell flange, while 09663126601 features M3 threaded board-side flange. Selection depends on the mounting method required by the application. If M3 threaded mounting is required, only the 09663126601 is suitable.

Q: What is the current rating difference between the FCC17B25SC65B and HARTING alternatives?

A: The FCC17B25SC65B and all FCE17 variants are rated for 5A continuous current. The HARTING 09663126600 and 09663126601 are rated for 6.5A. The higher HARTING rating provides additional current capacity margin. For applications operating at or near 5A, both part families are suitable. For applications requiring current capacity above 5A, the HARTING parts provide additional headroom.

Q: What is the operating temperature range difference?

A: The FCC17B25SC65B and FCE17 series operate from -40°C to 85°C. The HARTING parts operate from -55°C to 125°C, providing extended low-temperature and high-temperature performance. For applications requiring operation outside the -40°C to 85°C range, the HARTING alternatives are necessary.

Q: Are the contact materials compatible between Amphenol and HARTING parts?

A: The FCC17B25SC65B and FCE17 series use phosphor bronze contacts with gold plating (15.0µin). The HARTING parts use copper alloy contacts with unspecified finish. Both material systems are standard for D-Sub connectors and are compatible with standard mating plugs. The gold plating on Amphenol parts provides enhanced corrosion resistance and contact reliability compared to unspecified HARTING finish.
