Engineering Selection Recommendations

Amphenol ICC FCE17 Series (Preferred Substitutes)

The FCE17C37SC48B, FCE17C37SC40B, FCE17C37SC41B, FCE17C37SC44B, FCE17C37SC45B, FCE17C37SC49B, FCE17C37SC4DB, and FCE17C37SC4EB represent the primary equivalent alternatives to the obsolete FCC17C37SC48B. All FCE17 variants maintain identical mechanical and electrical specifications across connector configuration, mounting type, current rating, operating temperature range, and flammability rating. These parts are active products with RoHS compliance status, addressing regulatory requirements that the original FCC17C37SC48B does not satisfy. The FCE17 series incorporates glass-filled thermoplastic dielectric material, providing enhanced mechanical properties compared to standard thermoplastic formulations.

HARTING Alternatives (Secondary Substitutes)

The HARTING 09644147232 and 09664127600 connectors satisfy core D-Sub 37 position receptacle requirements with through-hole right-angle solder termination. These parts are suitable for applications where the following parameter variations are acceptable: reduced backset spacing (0.401" to 0.409" versus 0.590"), increased current rating (6.5A to 7.5A), extended operating temperature range (-55°C to 125°C), and alternative flange mounting configurations. HARTING parts carry ROHS3 compliance certification. Selection of HARTING alternatives requires confirmation that printed circuit board layout and mechanical mounting accommodate the reduced backset spacing.

Compliance Considerations

Applications subject to RoHS directives must employ FCE17 or HARTING alternatives, as the FCC17C37SC48B is non-compliant. The FCE17 series provides direct functional replacement with improved regulatory status. HARTING parts offer extended environmental operating range suitable for industrial applications requiring -55°C minimum temperature performance.

Frequently Asked Questions (FAQ)

Q: Can FCE17C37SC48B directly replace FCC17C37SC48B in existing designs?

A: Yes. The FCE17C37SC48B maintains identical specifications for connector style, position count, shell size, mounting type, termination method, current rating, operating temperature range, and flammability rating. The primary differences are product status (active versus obsolete) and RoHS compliance. No design modifications are required for mechanical or electrical compatibility.

Q: What distinguishes the multiple FCE17 variants (SC40B, SC41B, SC44B, SC45B, SC49B, SC4DB, SC4EB)?

A: All FCE17 variants share identical core specifications. The alphanumeric suffix designates internal contact finish thickness specifications and dielectric material formulations. Selection among FCE17 variants depends on specific application requirements for contact durability and dielectric properties. All variants are functionally interchangeable for standard 37 position D-Sub receptacle applications.

Q: Are HARTING connectors compatible with FCC17C37SC48B applications?

A: HARTING 09644147232 and 09664127600 connectors are mechanically and electrically compatible for D-Sub 37 position receptacle functions. However, backset spacing differs significantly (0.401" to 0.409" versus 0.590"). Compatibility requires verification that printed circuit board layout accommodates reduced backset spacing. HARTING parts offer higher current ratings and extended operating temperature range, suitable for demanding industrial environments.

Q: What is backset spacing and why does it matter?

A: Backset spacing is the distance from the connector mounting flange to the rear of the connector body. The FCC17C37SC48B and all FCE17 variants specify 0.590" (14.99mm) backset spacing. HARTING alternatives use 0.401" to 0.409" spacing. Printed circuit board design must accommodate the specific backset spacing of the selected connector. Mismatched backset spacing results in improper connector seating and potential electrical or mechanical failure.

Q: Does RoHS compliance affect electrical performance?

A: RoHS compliance addresses material composition and hazardous substance restrictions. The FCE17 series achieves RoHS compliance through material selection without compromising electrical performance. Current rating, voltage rating, operating temperature range, and contact resistance remain equivalent to the non-compliant FCC17C37SC48B. RoHS compliance is a regulatory requirement for many applications but does not alter functional electrical characteristics.

Q: Can I use FCE17 parts in applications originally designed for FCC17?

A: Yes. The FCE17 series provides direct functional replacement. Existing printed circuit board layouts, connector mating interfaces, and electrical specifications remain compatible. The transition from FCC17 to FCE17 requires no design modifications. This substitution is recommended for new production runs and design updates to ensure regulatory compliance and product availability.

Q: What is the significance of the glass-filled thermoplastic dielectric in FCE17 parts?

A: Glass-filled thermoplastic dielectric material enhances mechanical strength and dimensional stability compared to standard thermoplastic formulations. This material composition improves resistance to thermal stress and mechanical deformation during assembly and operation. The FCE17 series maintains the same electrical performance as the FCC17 while providing improved mechanical durability through advanced dielectric material selection.

Q: Are there inventory considerations when selecting substitute parts?

A: Yes. Current inventory levels vary across substitute options. FCE17C37SC48B (1029 units), FCE17C37SC40B (1119 units), FCE17C37SC41B (1046 units), FCE17C37SC44B (950 units), FCE17C37SC45B (941 units), FCE17C37SC49B (762 units), FCE17C37SC4DB (965 units), and FCE17C37SC4EB (727 units) are available from Amphenol ICC. HARTING 09644147232 (715 units) and 09664127600 (930 units) are available from HARTING. Selection based on immediate availability requirements should consider current stock levels.

Q: What certifications apply to these D-Sub connectors?

A: All listed connectors carry UL94 V-0 material flammability rating. FCE17 variants are RoHS Compliant. HARTING parts are ROHS3 Compliant and REACH Unaffected. All parts are classified under ECCN EAR99 and HTSUS 8536.69.4040. Specific application requirements may necessitate additional certifications or compliance documentation beyond those listed.
