Engineering Selection Recommendations

Amphenol ICC FCE17 Series (FCE17C37SB450, FCE17C37SB400, FCE17C37SB410, FCE17C37SB440, FCE17C37SB480, FCE17C37SB490, FCE17C37SB4D0, FCE17C37SB4E0):

The FCE17 series represents the direct active-product replacement for the obsolete FCC17C37SB450. All eight variants maintain identical mechanical and electrical specifications across the critical parameters: 37-position configuration, 5A current rating, -40°C to 85°C operating range, and UL94 V-0 flammability rating. The primary advantage of the FCE17 series is RoHS compliance, addressing regulatory requirements for new designs and manufacturing. These parts are available in higher inventory quantities (659 to 1138 units) and carry active product status, ensuring long-term supply continuity. The suffix variations (450, 400, 410, 440, 480, 490, 4D0, 4E0) represent internal configuration differences that do not affect functional compatibility in standard D-Sub receptacle applications.

HARTING 09644147232:

This connector provides functional substitution with enhanced electrical performance. The 09644147232 maintains the 37-position D-Sub receptacle configuration, through-hole right-angle mounting, and solder termination. It exceeds the FCC17C37SB450 in current rating (7.5A versus 5A) and operating temperature range (-55°C to 125°C versus -40°C to 85°C). The connector features machined contacts and includes mounting brackets as an additional feature. The HARTING part carries ROHS3 compliance and REACH unaffected status. The voltage rating is specified at 100V, which is lower than the FCC17C37SB450 (200V). Backset spacing is 0.401" (10.20mm), within acceptable tolerance of the original 0.405" (10.29mm). This option is suitable for applications requiring extended temperature performance and higher current capacity.

HARTING 09664127600:

This connector offers functional substitution with alternative dielectric material composition. The 09664127600 maintains the 37-position D-Sub receptacle configuration, through-hole right-angle mounting, and solder termination. It provides a 6.5A current rating and extended operating temperature range (-55°C to 125°C). The connector uses stamped contacts and polybutylene terephthalate (PBT) with glass fill for the dielectric material. The flange feature is unthreaded, differing from the 4-40 threaded mounting of the original part. Backset spacing is 0.409" (10.40mm), within acceptable tolerance. This option carries ROHS3 compliance and REACH unaffected status. The unthreaded flange may require alternative mounting methods compared to the original 4-40 configuration.

Frequently Asked Questions (FAQ)

Q: Can the FCE17C37SB450 directly replace the FCC17C37SB450 in existing designs?

A: Yes. The FCE17C37SB450 maintains all critical mechanical and electrical parameters: 37-position configuration, 5A current rating, -40°C to 85°C operating temperature, UL94 V-0 flammability rating, through-hole right-angle mounting, and solder termination. The primary difference is RoHS compliance status. The FCE17C37SB450 is suitable for direct substitution in new designs and manufacturing processes requiring RoHS compliance.

Q: What is the difference between the multiple FCE17 variants (FCE17C37SB400, SB410, SB440, SB480, SB490, SB4D0, SB4E0)?

A: All FCE17 variants maintain identical electrical and mechanical specifications for the 37-position D-Sub receptacle configuration. The suffix characters represent internal configuration variations that do not affect functional compatibility in standard applications. All variants are interchangeable from a performance and compatibility standpoint.

Q: Are the HARTING connectors fully compatible with the FCC17C37SB450?

A: The HARTING 09644147232 and 09664127600 provide functional substitution with specific parameter variations. Both maintain the 37-position D-Sub receptacle configuration, through-hole right-angle mounting, and solder termination. The HARTING 09644147232 features a 4-40 threaded flange identical to the original part, while the 09664127600 has an unthreaded flange. Both HARTING options provide extended operating temperature ranges (-55°C to 125°C) and higher current ratings (6.5A to 7.5A) compared to the original 5A specification. Backset spacing differences are within acceptable tolerance ranges.

Q: What is the significance of the RoHS compliance difference between FCC17C37SB450 and FCE17 series?

A: The FCC17C37SB450 is RoHS non-compliant, while the FCE17 series is RoHS compliant. RoHS compliance is mandatory for products manufactured for or sold into European Union markets and many other regulated regions. For new designs, manufacturing processes, and applications subject to RoHS requirements, the FCE17 series is the appropriate selection. Existing legacy systems using the FCC17C37SB450 may continue operation without modification.

Q: How do the dielectric materials differ between substitute options?

A: The FCC17C37SB450 uses thermoplastic dielectric material. The FCE17 series uses thermoplastic with glass fill, providing enhanced mechanical and thermal properties. The HARTING 09644147232 uses polycyclohexylenedimethylene terephthalate (PCT), while the 09664127600 uses polybutylene terephthalate (PBT) with glass fill. All materials maintain UL94 V-0 flammability rating. Glass-filled variants provide improved dimensional stability and thermal performance.

Q: What are the inventory considerations for selecting a substitute part?

A: The FCC17C37SB450 has 814 units in stock with obsolete status. The FCE17 series variants have higher inventory levels ranging from 659 to 1138 units with active product status, ensuring continued availability. The HARTING 09644147232 has 715 units available, and the 09664127600 has 930 units available. For long-term supply security, active-status parts (FCE17 series and HARTING options) are preferable to obsolete parts.

Q: Are there any mounting differences between the original part and substitutes?

A: The FCC17C37SB450, FCE17 series, and HARTING 09644147232 all feature 4-40 threaded flange mounting. The HARTING 09664127600 features an unthreaded flange, requiring alternative mounting methods. Backset spacing is 0.405" (10.29mm) for the original and FCE17 series, 0.401" (10.20mm) for the HARTING 09644147232, and 0.409" (10.40mm) for the 09664127600. These spacing variations are within acceptable tolerance for standard PCB mounting applications.

Q: What contact material differences exist between substitute options?

A: The FCC17C37SB450 and FCE17 series use phosphor bronze contacts with gold plating. The HARTING options use copper alloy contacts. Phosphor bronze provides superior corrosion resistance and contact reliability. Gold plating on the FCC17 and FCE17 series ensures low contact resistance and long-term reliability. The HARTING copper alloy contacts are suitable for standard signal applications but may require consideration for high-reliability or corrosive environment applications.
