Substitute parts are grouped into two categories:
Category 1: Direct Amphenol ICC Equivalents (FCE17 Series) These parts maintain full electrical and mechanical compatibility with the FCC17B25SC20B. The FCE17 series represents the active production equivalent to the obsolete FCC17 series. All FCE17B25SC variants share identical core specifications with the main part, including connector geometry, contact configuration, and electrical ratings. These parts differ only in dielectric material composition (thermoplastic with glass filling) and RoHS compliance status (RoHS Compliant). The voltage rating specification is not provided for FCE17 variants but does not preclude substitution given identical electrical performance parameters.
Category 2: Alternative Manufacturer Equivalents (HARTING) The HARTING 09663126600 and 09663126601 connectors provide functional equivalence with notable parameter variations. These parts maintain the same connector style, position count, mounting configuration, and solder termination. However, they differ in backset spacing (0.409" vs. 0.590"), current rating (6.5A vs. 5A), operating temperature range (-55°C ~ 125°C vs. -40°C ~ 85°C), contact form (stamped vs. machined), and flange feature configuration. The HARTING 09663126601 includes M3 threaded mounting provisions, distinguishing it from the unthreaded housing of the main part.

Engineering Selection Recommendations
Primary Recommendation: FCE17 Series (Amphenol ICC)
The FCE17B25SC20B, FCE17B25SC21B, FCE17B25SC24B, FCE17B25SC25B, FCE17B25SC28B, FCE17B25SC29B, FCE17B25SC2DB, and FCE17B25SC2EB represent the direct active production equivalents to the obsolete FCC17B25SC20B. These parts are manufactured by the same supplier (Amphenol ICC) and maintain identical electrical and mechanical specifications. All FCE17 variants are RoHS Compliant, addressing regulatory requirements that the original FCC17B25SC20B does not meet. The FCE17 series incorporates glass-filled thermoplastic dielectric material, which enhances mechanical and thermal stability compared to the unfilled thermoplastic of the original part. All FCE17 variants are currently in active production with substantial inventory availability.
Secondary Recommendation: HARTING 09663126600 and 09663126601
The HARTING connectors provide functional equivalence for applications where the parameter variations are acceptable. These parts maintain the same connector style, position count, and solder termination. The HARTING parts offer enhanced current rating (6.5A vs. 5A) and extended operating temperature range (-55°C ~ 125°C vs. -40°C ~ 85°C), providing performance headroom for demanding applications. However, the reduced backset spacing (0.409" vs. 0.590") requires verification of PCB layout compatibility. The HARTING 09663126601 includes M3 threaded mounting provisions, which differs from the unthreaded housing of the FCC17B25SC20B and may require mechanical redesign. The HARTING 09663126600 maintains unthreaded housing configuration. Both HARTING parts are ROHS3 Compliant and currently in active production.
Compliance Considerations
Selection between FCE17 and HARTING alternatives depends on regulatory requirements. For applications subject to RoHS Directive compliance, the FCE17 series (RoHS Compliant) and HARTING parts (ROHS3 Compliant) are both acceptable. The original FCC17B25SC20B is RoHS non-compliant and unsuitable for new designs or applications requiring regulatory compliance.
Frequently Asked Questions (FAQ)
Q: Can the FCE17B25SC20B be used as a direct replacement for the FCC17B25SC20B?
A: Yes. The FCE17B25SC20B maintains identical electrical and mechanical specifications with the FCC17B25SC20B. Both connectors feature 25 positions, 2 rows, right-angle through-hole solder termination, 5A current rating, 0.590" backset spacing, and UL94 V-0 flammability rating. The FCE17B25SC20B is the active production equivalent and is recommended for all new applications and field replacements.
Q: What is the difference between the various FCE17B25SC variants (SC20B, SC21B, SC24B, SC25B, SC28B, SC29B, SC2DB, SC2EB)?
A: All FCE17B25SC variants share identical electrical and mechanical specifications. The suffix designations (20B, 21B, 24B, 25B, 28B, 29B, 2DB, 2EB) represent internal Amphenol ICC part numbering conventions that do not affect connector performance or compatibility. All variants are interchangeable from an electrical and mechanical standpoint.
Q: Are the HARTING 09663126600 and 09663126601 fully compatible with the FCC17B25SC20B?
A: The HARTING connectors provide functional equivalence with notable parameter differences. Both maintain the same connector style, position count, and solder termination. However, the backset spacing differs (0.409" vs. 0.590"), which requires verification of PCB layout compatibility. The HARTING 09663126601 includes M3 threaded mounting provisions, distinguishing it from the unthreaded housing of the FCC17B25SC20B. The HARTING 09663126600 maintains unthreaded housing. These differences may require mechanical redesign depending on application requirements.
Q: What is backset spacing and why does it matter?
A: Backset spacing is the distance from the rear of the connector shell to the solder contact termination points on the PCB. The FCC17B25SC20B and all FCE17 variants specify 0.590" (14.99mm) backset spacing. The HARTING parts specify 0.409" (10.40mm). This parameter is critical for PCB layout design. Connectors with different backset spacing cannot be substituted without PCB redesign.
Q: Why is the FCC17B25SC20B classified as obsolete?
A: The FCC17B25SC20B is obsolete due to its RoHS non-compliant status and replacement by the active FCE17 series. The FCE17 series represents the current production standard for this connector configuration and incorporates improved dielectric materials and regulatory compliance.
Q: Can I use a HARTING connector in an application designed for the FCC17B25SC20B?
A: Substitution requires verification of three critical factors: (1) PCB layout compatibility with the different backset spacing (0.409" vs. 0.590"), (2) mechanical compatibility with the flange feature configuration (HARTING 09663126601 includes M3 threaded provisions), and (3) application requirements for the extended operating temperature range (-55°C ~ 125°C) and higher current rating (6.5A). If these parameters are compatible with your application, HARTING connectors are functionally equivalent.
Q: What does RoHS Compliant mean and why does it matter?
A: RoHS (Restriction of Hazardous Substances) Compliance indicates that the connector meets regulatory requirements restricting the use of specific hazardous materials including lead, cadmium, mercury, and hexavalent chromium. The FCC17B25SC20B is RoHS non-compliant. The FCE17 series is RoHS Compliant, and HARTING parts are ROHS3 Compliant. For applications subject to RoHS Directive requirements, only compliant parts are acceptable.
Q: What is the difference between RoHS Compliant and ROHS3 Compliant?
A: ROHS3 represents the third iteration of the RoHS Directive with expanded scope and updated substance restrictions. Both RoHS Compliant and ROHS3 Compliant designations indicate regulatory compliance. ROHS3 Compliant parts meet the most current regulatory requirements.
Q: Are there any inventory considerations when selecting a substitute?
A: Yes. The FCE17B25SC2DB variant has the highest inventory availability (1123 Pcs), followed by FCE17B25SC24B (1042 Pcs). The HARTING 09663126601 has 1073 Pcs available. The FCC17B25SC20B has 898 Pcs in stock but is obsolete. For applications requiring immediate availability, the FCE17B25SC2DB is recommended.
Q: Can I mix FCC17 and FCE17 connectors in the same application?
A: Yes. The FCC17B25SC20B and FCE17 series are electrically and mechanically equivalent. However, for new designs and applications subject to RoHS compliance requirements, the FCE17 series is recommended exclusively.
