Amphenol ICC FCE17 Series (FCE17C37SC21B, FCE17C37SC20B, FCE17C37SC24B, FCE17C37SC25B, FCE17C37SC28B, FCE17C37SC29B, FCE17C37SC2DB, FCE17C37SC2EB) represent direct parametric equivalents with identical mechanical and electrical specifications. These parts differ only in contact finish thickness specifications or dielectric material composition (Thermoplastic, Glass Filled versus standard Thermoplastic). All FCE17 variants are active products with RoHS Compliant status.

HARTING 09644147232 and 09664127600 are similar D-Sub 37 position receptacles with equivalent connector configuration but differ in backset spacing, current rating, voltage rating, and operating temperature range. These parts are classified as similar rather than direct equivalents due to parametric variations.

Engineering Selection Recommendations

Direct Equivalents (Amphenol ICC FCE17 Series):

The FCE17C37SC21B, FCE17C37SC20B, FCE17C37SC24B, FCE17C37SC25B, FCE17C37SC28B, FCE17C37SC29B, FCE17C37SC2DB, and FCE17C37SC2EB connectors are parametric equivalents of the FCC17C37SC21B. All eight variants maintain identical mechanical and electrical specifications including connector configuration, mounting type, termination method, current rating, operating temperature range, and material flammability rating. The primary distinction is product status: all FCE17 variants are active products, whereas the FCC17C37SC21B is obsolete.

All FCE17 series parts are RoHS Compliant, addressing regulatory requirements that the original FCC17C37SC21B does not satisfy. These parts are suitable for direct substitution in new designs and for replacement in existing applications where RoHS compliance is required or preferred.

Similar Alternatives (HARTING Components):

The HARTING 09644147232 and 09664127600 connectors are similar D-Sub 37 position receptacles with equivalent connector configuration but differ in critical parameters. The 09644147232 features a reduced backset spacing of 0.401" (10.20mm) compared to 0.590" (14.99mm) and a higher current rating of 7.5A. The 09664127600 has a backset spacing of 0.409" (10.40mm) and a current rating of 6.5A. Both HARTING parts support extended operating temperature ranges of -55°C to 125°C and are ROHS3 Compliant.

These HARTING alternatives are suitable only when the specific parametric differences (backset spacing, current rating, and operating temperature) align with application requirements. Direct mechanical and electrical compatibility cannot be assumed without design verification.

Frequently Asked Questions (FAQ)

Q: Can FCE17C37SC21B be used as a direct replacement for FCC17C37SC21B?

A: Yes. The FCE17C37SC21B is a parametric equivalent with identical mechanical and electrical specifications. The primary differences are product status (active versus obsolete) and RoHS compliance (compliant versus non-compliant). All mounting, termination, and electrical characteristics are equivalent.

Q: What is the difference between the various FCE17 part numbers (SC20B, SC24B, SC25B, SC28B, SC29B, SC2DB, SC2EB)?

A: All FCE17 variants share identical mechanical and electrical specifications. The alphanumeric suffix designates internal specification variations not detailed in the provided parameters. All eight variants are functionally equivalent for connector configuration, mounting type, termination method, current rating, and operating temperature range.

Q: Are HARTING 09644147232 and 09664127600 direct substitutes?

A: No. While these HARTING connectors maintain the same 37 position, 2-row D-Sub configuration, they differ in backset spacing and current rating. The 09644147232 has a backset spacing of 0.401" (10.20mm) and 7.5A current rating, while the 09664127600 has 0.409" (10.40mm) spacing and 6.5A rating. The original FCC17C37SC21B specifies 0.590" (14.99mm) backset spacing and 5A current rating. These differences may affect PCB layout compatibility and circuit performance.

Q: What does backset spacing mean?

A: Backset spacing is the distance from the rear of the connector shell to the solder cup termination points. This dimension is critical for PCB layout design. The FCC17C37SC21B and all FCE17 variants specify 0.590" (14.99mm), while HARTING alternatives specify different values. Substitution with different backset spacing requires PCB redesign.

Q: Is the FCC17C37SC21B RoHS compliant?

A: No. The FCC17C37SC21B is RoHS non-compliant. All FCE17 series equivalents are RoHS Compliant, making them suitable for applications subject to RoHS regulations.

Q: What is the difference between Phosphor Bronze and Copper Alloy contact materials?

A: The FCC17C37SC21B and all FCE17 equivalents use Phosphor Bronze contacts. The HARTING alternatives use Copper Alloy contacts. Both materials provide electrical conductivity and mechanical durability, but Phosphor Bronze offers superior spring characteristics and wear resistance in connector applications.

Q: Can I use a HARTING connector if my application requires the exact backset spacing of 0.590" (14.99mm)?

A: No. The HARTING 09644147232 specifies 0.401" (10.20mm) backset spacing, and the 09664127600 specifies 0.409" (10.40mm). Neither matches the 0.590" (14.99mm) specification of the FCC17C37SC21B. Using a connector with different backset spacing will result in solder joint misalignment and potential circuit failure.

Q: What is the operating temperature range difference between FCC17C37SC21B and HARTING alternatives?

A: The FCC17C37SC21B and FCE17 equivalents operate from -40°C to 85°C. The HARTING 09644147232 and 09664127600 operate from -55°C to 125°C, providing extended temperature capability. Selection depends on application thermal requirements.

Q: Are all FCE17 variants available in the same inventory quantities?

A: No. Inventory levels vary: FCE17C37SC21B (820 pcs), FCE17C37SC20B (867 pcs), FCE17C37SC24B (959 pcs), FCE17C37SC25B (736 pcs), FCE17C37SC28B (927 pcs), FCE17C37SC29B (850 pcs), FCE17C37SC2DB (806 pcs), and FCE17C37SC2EB (875 pcs). Procurement should account for availability when selecting among equivalent variants.
