Number of rows (2)
Shell size and layout (4 / DC, C)
Mounting type (Through Hole, Right Angle)
Termination method (Solder)
Flange feature type (Board Side with 4-40 mounting)
Material flammability rating (UL94 V-0)
Contact finish (Gold)
Contact finish thickness (15.0µin / 0.38µm)
Contact material (Phosphor Bronze)
Dielectric material composition (Thermoplastic or Thermoplastic, Glass Filled)
Operating temperature range (-40°C ~ 85°C)
Moisture sensitivity level (1 / Unlimited)

Secondary Considerations:

Current rating (5A nominal)

Engineering Selection Recommendations

Amphenol ICC FCE17 Series (Primary Substitutes)

The FCE17C37SC40B, FCE17C37SC41B, FCE17C37SC44B, FCE17C37SC45B, FCE17C37SC48B, FCE17C37SC49B, FCE17C37SC4DB, and FCE17C37SC4EB represent the most direct substitutes for the obsolete FCC17C37SC40B. All FCE17 variants maintain identical electrical and mechanical specifications across connector style, position count, shell size, mounting configuration, termination method, and flange design. These parts are manufactured by the same supplier (Amphenol ICC) and are classified as active products.

The primary distinction between the FCC17 and FCE17 series is RoHS compliance status. All FCE17 variants are RoHS Compliant, whereas the FCC17C37SC40B is RoHS non-compliant. The FCE17 series incorporates glass-filled thermoplastic dielectric material compared to the standard thermoplastic in the original part, providing enhanced mechanical and thermal properties while maintaining functional equivalence.

HARTING Alternatives (Secondary Substitutes)

The HARTING parts 09644147232 and 09664127600 provide functional equivalence with notable parameter variations. Both maintain the D-Sub 37-position receptacle configuration with through-hole right-angle solder termination and UL94 V-0 flammability rating. However, these alternatives differ in the following aspects:

Backset spacing: 0.401" (10.20mm) for 09644147232 and 0.409" (10.40mm) for 09664127600, compared to 0.590" (14.99mm) for the FCC17C37SC40B
Current rating: 7.5A (09644147232) and 6.5A (09664127600), compared to 5A for the original part
Operating temperature range: -55°C ~ 125°C, compared to -40°C ~ 85°C for the FCC17C37SC40B
Flange feature: Housing/Shell mounted, compared to Board Side mounting on the original part
Contact material: Copper Alloy, compared to Phosphor Bronze
Dielectric material: PCT or PBT-based compositions, compared to Thermoplastic

HARTING alternatives are suitable only when PCB layout accommodates the reduced backset spacing and when the flange mounting configuration is compatible with housing/shell attachment rather than board-side mounting.

Compliance and Regulatory Status

For applications requiring RoHS compliance, the FCE17 series is mandatory. All FCE17 variants and HARTING alternatives are RoHS Compliant or ROHS3 Compliant. The original FCC17C37SC40B does not meet RoHS requirements and should be replaced in new designs or production runs subject to RoHS regulations.

All substitute parts maintain MSL 1 (Unlimited) moisture sensitivity classification, consistent with the original part.

Frequently Asked Questions (FAQ)

Q: Can FCE17C37SC40B directly replace FCC17C37SC40B in existing designs?

A: Yes. The FCE17C37SC40B is a direct parametric equivalent with identical connector style, position count, shell size, mounting type, termination method, and flange configuration. The primary difference is RoHS compliance status and dielectric material composition (glass-filled thermoplastic versus standard thermoplastic). Electrical and mechanical performance are equivalent.

Q: What is the difference between the various FCE17 part numbers (SC40B, SC41B, SC44B, SC45B, SC48B, SC49B, SC4DB, SC4EB)?

A: All FCE17 variants listed maintain identical electrical and mechanical specifications. The suffix designations (40B, 41B, 44B, 45B, 48B, 49B, 4DB, 4EB) represent internal Amphenol ICC product line variations that do not affect functional equivalence. Selection among these variants should be based on inventory availability and lead time requirements.

Q: Are HARTING parts 09644147232 and 09664127600 suitable replacements?

A: HARTING parts provide functional equivalence for D-Sub 37-position receptacle applications but include parameter variations that require design verification. The reduced backset spacing (0.401" or 0.409" versus 0.590") and housing/shell flange mounting (versus board-side mounting) necessitate PCB layout compatibility assessment. These alternatives are suitable only when the mechanical mounting configuration and spacing requirements align with the original design.

Q: What is the significance of the dielectric material change from Thermoplastic to Thermoplastic, Glass Filled in the FCE17 series?

A: Glass-filled thermoplastic dielectric material provides enhanced mechanical strength, improved dimensional stability, and superior thermal performance compared to standard thermoplastic. This material upgrade does not affect electrical performance or connector functionality but improves long-term reliability and environmental resistance. The change is transparent to electrical circuit operation.

Q: Does the FCC17C37SC40B meet current RoHS requirements?

A: No. The FCC17C37SC40B is classified as RoHS non-compliant. For applications subject to RoHS regulations (EU Directive 2011/65/EU or equivalent), the FCE17 series (all variants) must be specified. All FCE17 parts are RoHS Compliant.

Q: Can I use a higher current-rated substitute such as HARTING 09644147232 (7.5A) in place of the 5A-rated FCC17C37SC40B?

A: Higher current rating does not create compatibility issues for applications operating at or below the original 5A specification. However, the HARTING alternative introduces other parameter variations (backset spacing, flange mounting type, contact material, dielectric material) that require comprehensive design review beyond current rating alone.

Q: What is the operating temperature range difference between FCC17C37SC40B and HARTING alternatives?

A: The FCC17C37SC40B operates from -40°C to 85°C. HARTING parts 09644147232 and 09664127600 operate from -55°C to 125°C, providing extended low-temperature and high-temperature capability. This expanded range is beneficial for applications requiring operation in extreme thermal environments but is not required for designs limited to the original -40°C ~ 85°C specification.

Q: Are all substitute parts available in the same packaging format?

A: The FCC17C37SC40B packaging is not specified in the provided data. Amphenol ICC FCE17 variants are available in standard packaging. HARTING parts are supplied in Bulk packaging. Packaging format should be confirmed with suppliers based on specific procurement and assembly requirements.

Q: What is the contact finish specification for HARTING alternatives?

A: Contact finish specifications are not provided for HARTING parts 09644147232 and 09664127600. The FCC17C37SC40B and all FCE17 variants specify gold contact finish at 15.0µin (0.38µm) thickness. Contact finish details for HARTING alternatives should be obtained directly from the manufacturer for applications requiring specific contact plating specifications.

Q: Is the Phosphor Bronze contact material in FCC17C37SC40B functionally equivalent to the Copper Alloy contacts in HARTING alternatives?

A: Both Phosphor Bronze and Copper Alloy contact materials are suitable for D-Sub connector applications and provide adequate electrical conductivity and mechanical properties. However, they represent different material specifications. Substitution should be evaluated based on specific application requirements for contact resistance, wear characteristics, and environmental compatibility.
