Engineering Selection Recommendations

Amphenol ICC FCE17 Series (Primary Recommendation)

The FCE17B25SC61B, FCE17B25SC60B, FCE17B25SC64B, FCE17B25SC65B, FCE17B25SC68B, FCE17B25SC69B, FCE17B25SC6DB, and FCE17B25SC6EB represent direct functional equivalents to the obsolete FCC17B25SC61B. All FCE17 variants maintain identical mechanical and electrical specifications across connector geometry, pin count, mounting configuration, and current/voltage ratings. The primary distinction is product status: all FCE17 models are active production components, ensuring long-term availability and supply chain continuity.

A significant advantage of the FCE17 series is RoHS compliance. All FCE17 variants meet RoHS requirements, whereas the original FCC17B25SC61B is non-compliant. For applications subject to RoHS directives or customer requirements, FCE17 substitution is necessary. Dielectric material composition differs slightly (FCE17 models incorporate glass-filled thermoplastic versus unfilled thermoplastic in the original), which enhances mechanical and thermal properties without affecting electrical performance within specified operating ranges.

Inventory availability across the FCE17 range is robust, with individual part quantities ranging from 719 to 1150 units in stock. Selection among FCE17 variants may be based on specific application requirements or internal design documentation references, as all variants are electrically and mechanically interchangeable.

HARTING 09663126600 and 09663126601 (Alternative Substitutes)

The HARTING models 09663126600 and 09663126601 provide compatible alternatives when Amphenol ICC components are unavailable. Both HARTING parts maintain core D-Sub 25-position receptacle architecture with through-hole right-angle solder termination and UL94 V-0 flammability rating.

Key differences from the FCC17B25SC61B include:

Backset spacing: HARTING parts specify 0.409" (10.40mm) versus 0.590" (14.99mm) for the original. This dimensional variance may affect PCB layout compatibility and requires physical verification before substitution.
Flange feature: Model 09663126600 features an unthreaded housing/shell flange, while 09663126601 provides an M3 threaded flange. The original FCC17B25SC61B specifies board-side M3 flange, making 09663126601 the more compatible HARTING option.
Contact finish: HARTING parts do not specify contact finish or thickness, whereas the original provides gold plating at 15.0µin (0.38µm).
Operating temperature: HARTING models support -55°C ~ 125°C, exceeding the original -40°C ~ 85°C range.
Current rating: HARTING parts are rated for 6.5A, exceeding the 5A specification of the original.

HARTING components are ROHS3 compliant and carry REACH unaffected status. Both models are in active production with inventory availability of 734 and 1073 units respectively.

Compliance and Certification Summary

For new designs or systems requiring regulatory compliance, FCE17 series substitution is strongly indicated due to RoHS compliance status. For legacy system maintenance where RoHS compliance is not mandated, all listed substitutes maintain UL94 V-0 flammability certification and MSL 1 moisture sensitivity rating, ensuring compatibility with existing assembly and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can I directly substitute an FCE17B25SC6X variant for the obsolete FCC17B25SC61B?

A: Yes. All FCE17 variants listed maintain identical connector geometry, pin configuration, mounting type, and electrical ratings. The parts are mechanically and electrically interchangeable. The primary advantage of FCE17 substitution is active product status and RoHS compliance.

Q: What is the significance of the different FCE17 part number suffixes (SC60B, SC64B, SC65B, SC68B, SC69B, SC6DB, SC6EB)?

A: The suffix variations reflect internal design or manufacturing process differences that do not affect electrical or mechanical performance within the specified operating parameters. All variants meet identical functional requirements and are suitable for the same applications. Selection may be based on design documentation references, internal part numbering systems, or supplier availability.

Q: Are the HARTING 09663126600 and 09663126601 fully compatible with the FCC17B25SC61B?

A: Both HARTING parts meet the core D-Sub 25-position receptacle requirements and maintain solder termination, through-hole mounting, and UL94 V-0 certification. However, backset spacing differs (0.409" versus 0.590"), which may affect PCB layout. The 09663126601 is more compatible due to its M3 threaded flange, matching the original board-side M3 specification. Physical verification of PCB hole patterns and mounting clearances is required before substitution.

Q: What is the impact of the dielectric material change from unfilled thermoplastic to glass-filled thermoplastic in FCE17 models?

A: Glass-filled thermoplastic provides enhanced mechanical strength and thermal stability compared to unfilled thermoplastic. This material upgrade does not degrade electrical performance and is compatible with the original operating temperature range of -40°C ~ 85°C. The change represents an improvement in component robustness without functional compromise.

Q: Why do FCE17 models not specify a voltage rating while the original FCC17B25SC61B specifies 200V?

A: The voltage rating specification is not provided in the FCE17 technical data. This does not indicate reduced voltage capability. For applications requiring explicit 200V rating confirmation, contact the manufacturer or consult detailed product datasheets. The absence of a specified voltage rating does not preclude use in 200V applications; it reflects differences in technical documentation practices between product generations.

Q: Is RoHS compliance mandatory for my application?

A: RoHS compliance is mandatory for products sold in the European Union and is increasingly required by OEMs and end customers globally. If your application is subject to RoHS directives or customer specifications, FCE17 series substitution is necessary. The original FCC17B25SC61B is RoHS non-compliant and cannot be used in RoHS-regulated applications.

Q: Can I mix FCC17B25SC61B and FCE17 connectors in the same assembly?

A: Mixing obsolete and active components is not recommended for new designs. For legacy system maintenance, component mixing is acceptable if all parts meet the application's electrical and mechanical requirements. However, standardizing on a single active part number (FCE17 variant) simplifies procurement, inventory management, and future maintenance.

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

A: Both designations indicate compliance with RoHS directives. ROHS3 refers to compliance with the third iteration of the RoHS directive (2011/65/EU as amended). RoHS Compliant indicates general RoHS compliance without specifying the directive version. Both are acceptable for regulatory purposes.

Q: Are there any thermal or electrical performance differences between the substitute parts?

A: All listed substitutes maintain the 5A current rating and -40°C ~ 85°C operating temperature range of the original, with the exception of HARTING parts, which exceed these specifications (6.5A, -55°C ~ 125°C). No performance degradation occurs with any listed substitute. HARTING components provide enhanced thermal and current margins.

Q: What should I verify before implementing a substitute part?

A: Verify the following before substitution: (1) PCB hole pattern and mounting hole spacing compatibility, particularly for HARTING parts with different backset spacing; (2) flange type and mounting mechanism (board-side M3 versus housing-shell variants); (3) contact finish requirements if gold plating is critical for your application; (4) RoHS compliance status if regulatory requirements apply; (5) supplier availability and lead times for production quantities.
