Engineering Selection Recommendations

Primary Recommendation: Amphenol ICC FCE17 Series

The FCE17C37SB4DB, FCE17C37SB40B, FCE17C37SB41B, FCE17C37SB44B, FCE17C37SB45B, FCE17C37SB48B, FCE17C37SB49B, and FCE17C37SB4EB represent direct functional equivalents to the obsolete FCC17C37SB4DB. All FCE17 variants maintain identical electrical and mechanical specifications including 37 positions, 2-row configuration, shell size 4 (DC, C), through-hole right-angle mounting, and 5A current rating. Critical advantages include active product status and RoHS compliance, addressing regulatory requirements for new designs and procurement cycles.

Secondary Recommendation: HARTING Alternatives

HARTING part numbers 09644147232 and 09664127600 satisfy core D-Sub receptacle functionality with 37 positions, 2-row configuration, and shell size 4 (DC, C). These alternatives provide enhanced current ratings (7.5A and 6.5A respectively) and extended operating temperature ranges (-55°C to 125°C). HARTING connectors feature different contact materials (Copper Alloy versus Phosphor Bronze) and dielectric compositions (PCT or PBT/Polyester/Glass Filled versus Thermoplastic/Glass Filled). These alternatives are suitable for applications requiring higher thermal performance or increased current capacity.

Compliance Considerations

The FCC17C37SB4DB is RoHS non-compliant. All Amphenol ICC FCE17 series substitutes are RoHS compliant. HARTING alternatives are ROHS3 compliant. Selection of compliant alternatives is required for applications subject to RoHS regulations.

Frequently Asked Questions (FAQ)

Q: Can FCE17C37SB4DB directly replace FCC17C37SB4DB in existing designs?

A: Yes. The FCE17C37SB4DB maintains identical electrical and mechanical parameters including connector type, position count, shell size, mounting configuration, termination method, current rating, and operating temperature range. The primary difference is product status (active versus obsolete) and RoHS compliance.

Q: What distinguishes the multiple FCE17 variants (SB4DB, SB40B, SB41B, SB44B, SB45B, SB48B, SB49B, SB4EB)?

A: All FCE17 variants listed share identical core specifications for positions, rows, shell size, mounting type, termination, current rating, and operating temperature. Differences exist in internal design codes (the suffix designations) but do not affect functional compatibility for standard D-Sub receptacle applications. Selection among variants should be based on availability and procurement lead times.

Q: Are HARTING connectors compatible with Amphenol ICC D-Sub receptacles?

A: HARTING 09644147232 and 09664127600 are mechanically and electrically compatible D-Sub receptacles with identical shell size 4 (DC, C) configuration and 37-position, 2-row layout. However, they feature different contact materials and dielectric compositions. Compatibility depends on specific application requirements regarding contact material interaction and thermal performance. HARTING alternatives provide higher current ratings and extended temperature ranges suitable for demanding environments.

Q: What is the significance of backset spacing differences?

A: Backset spacing defines the distance from the connector mounting face to the contact plane. The FCC17C37SB4DB specifies 0.405" (10.29mm). Amphenol ICC FCE17 variants maintain this specification. HARTING 09644147232 specifies 0.401" (10.20mm), and 09664127600 specifies 0.409" (10.40mm). These minor variations may affect PCB layout and mating connector alignment in space-constrained applications.

Q: Does contact finish thickness affect substitution decisions?

A: The FCC17C37SB4DB and all Amphenol ICC FCE17 variants specify 15.0µin (0.38µm) gold contact finish thickness. HARTING alternatives do not provide contact finish thickness specifications. For applications requiring specific contact finish specifications, Amphenol ICC FCE17 series maintains documented consistency.

Q: What is the impact of dielectric material differences?

A: The FCC17C37SB4DB uses Thermoplastic, Glass Filled dielectric material. Amphenol ICC FCE17 variants maintain this specification. HARTING 09644147232 uses Polycyclohexylenedimethylene Terephthalate (PCT), while 09664127600 uses Polybutylene Terephthalate (PBT), Polyester, Glass Filled. Dielectric material affects electrical properties, moisture absorption, and thermal stability. Selection should align with application environmental conditions and electrical performance requirements.

Q: Are there inventory considerations for part selection?

A: Current inventory levels are provided for reference. FCE17C37SB45B shows highest availability (1148 pcs), while FCE17C37SB48B shows lowest (714 pcs). HARTING 09664127600 provides 930 pcs availability. Inventory levels may fluctuate and should be confirmed with suppliers for production requirements.

Q: What certifications apply to each substitute option?

A: FCC17C37SB4DB carries UL94 V-0 flammability rating and is RoHS non-compliant. All Amphenol ICC FCE17 variants carry UL94 V-0 rating and are RoHS compliant. HARTING alternatives carry UL94 V-0 rating, are ROHS3 compliant, and include REACH Unaffected status. Regulatory requirements should drive selection between compliant alternatives.
