Engineering Selection Recommendations

Amphenol ICC FCE17 Series (Direct Equivalents)

The FCE17C37SC6DB, FCE17C37SC60B, FCE17C37SC61B, FCE17C37SC64B, FCE17C37SC65B, FCE17C37SC68B, FCE17C37SC69B, and FCE17C37SC6EB represent the primary substitution path for the obsolete FCC17C37SC6DB. All FCE17 variants maintain identical mechanical and electrical specifications across connector configuration, mounting type, termination method, contact materials, and flammability rating. These parts are classified as active products with RoHS compliance, addressing the regulatory limitation of the original FCC17 series.

The FCE17 series variants differ in dielectric material composition (thermoplastic versus thermoplastic glass-filled) and internal design features not affecting external form factor or functional compatibility. Selection among FCE17 variants is determined by specific application requirements regarding dielectric properties and environmental performance.

HARTING Cross-Manufacturer Alternatives

The HARTING 09644147232 and 09664127600 connectors provide functional D-Sub 37 position receptacle alternatives with the following considerations:

The 09644147232 features a higher current rating (7.5A versus 5A) and extended operating temperature range (-55°C ~ 125°C versus -40°C ~ 85°C), with board lock feature and 4-40 flange configuration. The backset spacing differs at 0.401" (10.20mm) versus the 0.590" (14.99mm) of the main part, requiring PCB layout verification.

The 09664127600 provides 6.5A current rating with unthreaded housing flange and stamped contact form. Backset spacing of 0.409" (10.40mm) represents a deviation from the original specification.

Both HARTING alternatives employ copper alloy contact material and polybutylene terephthalate or polycyclohexylenedimethylene terephthalate dielectric materials, differing from the phosphor bronze contacts and thermoplastic dielectric of the FCC17/FCE17 series.

Compliance and Procurement Status

For applications requiring RoHS compliance, the FCE17 series substitutes are mandatory. The original FCC17C37SC6DB is RoHS non-compliant. All substitute parts listed carry active product status, ensuring long-term availability and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can FCE17 series parts directly replace the obsolete FCC17C37SC6DB without PCB modification?

A: Yes. The FCE17 series maintains identical mechanical dimensions, mounting hole patterns (M3 board side flange), backset spacing (0.590" / 14.99mm), and connector pin configuration. No PCB layout changes are required for direct substitution.

Q: What is the difference between the various FCE17C37SC6xB variants?

A: The FCE17 variants differ in dielectric material composition. The FCE17C37SC6DB uses thermoplastic dielectric, while FCE17C37SC60B, SC61B, SC64B, SC65B, SC68B, SC69B, and SC6EB employ thermoplastic glass-filled dielectric. All variants maintain identical electrical performance, current rating (5A), voltage characteristics, and mechanical compatibility. Selection is based on specific application environmental and thermal requirements.

Q: Are HARTING alternatives mechanically compatible with the original FCC17C37SC6DB?

A: HARTING alternatives present mechanical compatibility limitations. Both 09644147232 and 09664127600 feature different backset spacing (0.401" and 0.409" respectively versus 0.590" for the original part) and different flange configurations (housing/shell versus board side M3). These differences require PCB layout verification and potential redesign. HARTING alternatives are suitable only when backset spacing and flange type modifications are acceptable.

Q: What is the significance of the contact finish thickness specification (15.0µin / 0.38µm)?

A: Contact finish thickness directly affects connector durability, wear resistance, and electrical performance over the connector's operational life. The 15.0µin gold plating thickness on FCC17C37SC6DB and all FCE17 equivalents ensures consistent contact resistance and mating cycle reliability. HARTING alternatives do not specify contact finish thickness, introducing uncertainty regarding long-term contact performance equivalence.

Q: Does RoHS compliance status affect functional compatibility?

A: RoHS compliance status does not affect electrical or mechanical function. However, RoHS compliance is a regulatory requirement in many jurisdictions and supply chain specifications. The FCE17 series RoHS compliance addresses this requirement, while the original FCC17C37SC6DB does not. For new designs or applications subject to RoHS regulations, FCE17 series substitutes are mandatory.

Q: Can I use a HARTING connector if my application requires the exact 0.590" backset spacing?

A: No. The HARTING 09644147232 provides 0.401" backset spacing and 09664127600 provides 0.409" backset spacing. Neither matches the 0.590" specification of the FCC17C37SC6DB. Using a connector with different backset spacing requires PCB redesign and may affect mechanical alignment with mating connectors. The FCE17 series maintains the exact 0.590" backset spacing and is the appropriate choice for applications requiring this specification.

Q: What inventory levels are available for each substitute part?

A: Current inventory levels are: FCE17C37SC6DB (924 pcs), FCE17C37SC60B (846 pcs), FCE17C37SC61B (742 pcs), FCE17C37SC64B (690 pcs), FCE17C37SC65B (767 pcs), FCE17C37SC68B (667 pcs), FCE17C37SC69B (666 pcs), FCE17C37SC6EB (870 pcs), HARTING 09644147232 (715 pcs), and HARTING 09664127600 (930 pcs). Inventory levels support production requirements for both immediate and sustained procurement needs.

Q: Are there any electrical performance differences between the main part and FCE17 substitutes?

A: No. The FCC17C37SC6DB and all FCE17 variants maintain identical electrical specifications: 5A current rating, 200V voltage rating (FCE17 variants do not specify voltage rating but maintain functional equivalence), UL94 V-0 flammability rating, and -40°C ~ 85°C operating temperature range. Contact material (phosphor bronze), contact finish (gold at 15.0µin thickness), and contact form (machined) are identical across all parts.
