FCC17C37SC20B D-Sub 37 Position Receptacle Equivalent & Substitute Parts

Part Overview

The FCC17C37SC20B is a 37 position D-Sub receptacle connector manufactured by Amphenol ICC (Commercial Products). This through-hole, right-angle solder termination connector features female sockets with a 2-row configuration in shell size 4 (DC, C). The part is classified as obsolete, necessitating identification of active equivalent and substitute components for ongoing design support and procurement continuity. Equivalent parts maintain identical electrical and mechanical specifications, while substitute parts provide functional alternatives within acceptable parameter tolerances for D-Sub receptacle applications.

Amphenol ICC FCE17 Series Parts: The FCE17C37SC20B, FCE17C37SC21B, FCE17C37SC24B, FCE17C37SC25B, FCE17C37SC28B, FCE17C37SC29B, and FCE17C37SC2DB/2EB represent direct parametric equivalents. These parts maintain identical connector geometry, position count, mounting configuration, and electrical ratings. The primary distinction is product status: all FCE17 variants are active, whereas the FCC17C37SC20B is obsolete. All FCE17 parts are RoHS compliant, contrasting with the non-compliant FCC17 series.

HARTING Cross-Manufacturer Alternatives: The 09644147232 and 09664127600 from HARTING provide functional D-Sub 37 position receptacle solutions with compatible through-hole right-angle solder termination. These parts accommodate the same connector footprint and pin configuration but exhibit variations in backset spacing, current rating, and operating temperature range.

Engineering Selection Recommendations

Amphenol ICC FCE17 Series (FCE17C37SC20B, FCE17C37SC21B, FCE17C37SC24B, FCE17C37SC25B, FCE17C37SC28B, FCE17C37SC29B, FCE17C37SC2DB, FCE17C37SC2EB):

These parts represent the primary equivalent alternatives to the obsolete FCC17C37SC20B. All FCE17 variants maintain identical electrical specifications (5A current rating, -40°C to 85°C operating range), mechanical configuration (37 positions, 2 rows, shell size 4, through-hole right-angle solder termination), and material standards (UL94 V-0 flammability rating). The FCE17 series is fully RoHS compliant, addressing regulatory requirements that the FCC17 series does not satisfy. All FCE17 parts are currently in active production status with substantial inventory availability (736 to 959 pieces in stock). Selection among FCE17 variants should be based on specific application requirements and internal part numbering conventions, as all variants are functionally equivalent for standard D-Sub 37 position receptacle applications.

HARTING 09644147232:

This part provides a cross-manufacturer alternative with enhanced electrical performance (7.5A current rating versus 5A) and extended operating temperature range (-55°C to 125°C versus -40°C to 85°C). The 09644147232 features board lock and filter capabilities with a backset spacing of 0.401" (10.20mm), differing from the 0.590" (14.99mm) spacing of the FCC17C37SC20B. This part is ROHS3 compliant and suitable for applications requiring higher current capacity or broader temperature operation. Mechanical compatibility with existing PCB layouts must be confirmed due to backset spacing variation.

HARTING 09664127600:

This alternative offers intermediate electrical performance (6.5A current rating) and extended operating temperature range (-55°C to 125°C). The backset spacing of 0.409" (10.40mm) differs from the original specification. This part is ROHS3 compliant and features stamped contact construction. PCB layout compatibility assessment is required prior to implementation due to backset spacing differences.

Frequently Asked Questions (FAQ)

Q: Can the FCE17C37SC20B directly replace the obsolete FCC17C37SC20B in existing designs?

A: Yes. The FCE17C37SC20B maintains identical electrical ratings (5A, 200V), mechanical configuration (37 positions, 2 rows, shell size 4, through-hole right-angle solder termination), operating temperature range (-40°C to 85°C), and physical dimensions (0.590" backset spacing). The primary difference is RoHS compliance status. No design modifications are required for direct substitution.

Q: What is the difference between the various FCE17C37SC2xB part numbers?

A: All FCE17C37SC2xB variants (SC20B, SC21B, SC24B, SC25B, SC28B, SC29B, SC2DB, SC2EB) are functionally equivalent D-Sub 37 position receptacles with identical electrical and mechanical specifications. The suffix designations reflect internal Amphenol ICC product line variations. Selection should be based on internal part numbering requirements or supplier availability. All variants are interchangeable for standard applications.

Q: Are the HARTING parts (09644147232 and 09664127600) compatible with PCBs designed for the FCC17C37SC20B?

A: Electrical and connector compatibility is maintained. However, the backset spacing differs: FCC17C37SC20B uses 0.590" (14.99mm), while 09644147232 uses 0.401" (10.20mm) and 09664127600 uses 0.409" (10.40mm). PCB layout verification is required to confirm mounting hole alignment before implementation. Current ratings also differ (7.5A and 6.5A respectively versus 5A), which may affect thermal performance in high-current applications.

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

A: The FCC17C37SC20B is RoHS non-compliant, while all FCE17 variants and HARTING alternatives are RoHS compliant or ROHS3 compliant. RoHS compliance restricts hazardous substances (lead, cadmium, mercury, hexavalent chromium, polybrominated biphenyls, and polybrominated diphenyl ethers) in electrical and electronic equipment. For applications subject to RoHS regulations or customer requirements, compliant alternatives must be selected.

Q: Can I use a higher current-rated part (HARTING 09644147232 at 7.5A) in place of the 5A-rated FCC17C37SC20B?

A: Higher current ratings provide additional design margin and do not create incompatibility. The 09644147232 is suitable for applications where the original 5A rating is adequate. However, backset spacing differences must be confirmed for PCB compatibility. The extended operating temperature range (-55°C to 125°C) of the HARTING part provides broader environmental capability than the original specification (-40°C to 85°C).

Q: What are the key parameters that determine substitution eligibility?

A: Substitution eligibility is determined by: connector type (receptacle, female sockets), position count (37), row configuration (2), shell size (4/DC/C), mounting style (through-hole right-angle), termination method (solder), current rating (minimum 5A), operating temperature range (minimum -40°C to 85°C), and flammability rating (UL94 V-0). Variations in backset spacing, contact material, or shell finish may require PCB layout verification or application-specific assessment.

Q: Is the contact finish thickness (15.0µin/0.38µm) critical for substitution?

A: Contact finish thickness affects long-term reliability and wear characteristics in mated connector cycles. The FCC17C37SC20B and all FCE17 variants specify identical gold plating thickness (15.0µin/0.38µm). HARTING parts do not specify contact finish thickness. For applications with high mating cycle requirements or stringent contact resistance specifications, matching finish thickness is recommended.

Q: What inventory considerations should guide part selection?

A: Current inventory levels are: FCC17C37SC20B (1102 pieces, obsolete status), FCE17C37SC20B (867 pieces), FCE17C37SC24B (959 pieces), FCE17C37SC28B (927 pieces), FCE17C37SC29B (850 pieces), FCE17C37SC2EB (875 pieces), 09644147232 (715 pieces), and 09664127600 (930 pieces). For new designs, active-status parts with sustained inventory levels are preferred. For legacy system support, the FCC17C37SC20B remains available but should be transitioned to active equivalents for long-term supply assurance.
