Engineering Selection Recommendations

Primary Recommendation: Amphenol ICC FCE17 Series

The FCE17C37SC44B, FCE17C37SC40B, FCE17C37SC41B, FCE17C37SC45B, FCE17C37SC48B, FCE17C37SC49B, FCE17C37SC4DB, and FCE17C37SC4EB represent the optimal substitutes for the obsolete FCC17C37SC44B. These parts maintain identical electrical and mechanical specifications while offering the following advantages:

Active product status with established supply chain availability
RoHS compliance for regulatory adherence
Identical connector interface and mounting footprint
Equivalent current and voltage ratings
Matching operating temperature range
Consistent material flammability certification (UL94 V-0)

The FCE17 series variants differ only in shell finish specifications (represented by the final alphanumeric code), which do not affect functional compatibility. Selection among these variants depends on specific finish requirements for the application.

Secondary Recommendation: HARTING Alternatives

HARTING part numbers 09644147232 and 09664127600 are suitable alternatives when the following parameter variations are acceptable:

Reduced backset spacing (0.401" or 0.409" versus 0.590")
Higher current ratings (6.5A to 7.5A versus 5A)
Extended operating temperature range (-55°C to 125°C versus -40°C to 85°C)
Different dielectric material composition
Different contact material (Copper Alloy versus Phosphor Bronze)

These parts maintain D-Sub 37 position receptacle configuration and through-hole right-angle solder termination but require mechanical layout verification due to backset spacing differences.

Frequently Asked Questions (FAQ)

Q: Can FCE17C37SC44B directly replace FCC17C37SC44B without PCB modification?

A: Yes. The FCE17C37SC44B maintains identical mounting footprint, flange configuration, and electrical interface specifications. No PCB layout changes are required for direct substitution.

Q: What is the difference between the various FCE17C37SC4xB part numbers?

A: The FCE17C37SC40B, FCE17C37SC41B, FCE17C37SC45B, FCE17C37SC48B, FCE17C37SC49B, FCE17C37SC4DB, and FCE17C37SC4EB variants differ only in shell finish specifications. All maintain identical electrical performance, mechanical dimensions, and connector interface characteristics. Selection is based on finish requirements for the specific application.

Q: Is the FCC17C37SC44B still available for procurement?

A: The FCC17C37SC44B is classified as obsolete. Current inventory of 806 pieces is available, but long-term supply cannot be assured. Migration to active FCE17 series equivalents is recommended for new designs and ongoing production requirements.

Q: What is the significance of RoHS compliance for this connector?

A: The FCC17C37SC44B is RoHS non-compliant, while all FCE17 series equivalents are RoHS compliant. RoHS compliance is required for products sold in the European Union and many other markets. Substitution to RoHS-compliant parts ensures regulatory compliance for current and future applications.

Q: Can HARTING 09644147232 be used in place of FCC17C37SC44B?

A: HARTING 09644147232 is functionally compatible for D-Sub 37 position receptacle applications but features a reduced backset spacing of 0.401" compared to 0.590" for the FCC17C37SC44B. PCB layout verification is required to confirm mechanical compatibility. The higher current rating (7.5A) and extended temperature range (-55°C to 125°C) may provide additional design margin for demanding applications.

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

A: Backset spacing is the distance from the mounting flange to the rear of the connector shell. The FCC17C37SC44B specifies 0.590" (14.99mm) backset spacing. HARTING alternatives feature reduced spacing (0.401" or 0.409"), which affects PCB layout and component placement. Verify backset spacing compatibility with your PCB design before substitution.

Q: Are all FCE17 series parts interchangeable with the FCC17C37SC44B?

A: All FCE17C37SC4xB variants maintain identical electrical and mechanical specifications required for direct substitution with FCC17C37SC44B. The final character code indicates shell finish variations that do not affect functional compatibility. Selection among variants depends on specific finish requirements.

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

A: All listed parts carry UL94 V-0 material flammability certification. The FCC17C37SC44B is RoHS non-compliant. All FCE17 series parts are RoHS compliant. HARTING parts are ROHS3 compliant and REACH unaffected. Verify certification requirements for your specific application and regulatory jurisdiction.
