Engineering Selection Recommendations

Amphenol ICC FCE17 Series (Direct Equivalents)

The FCE17C37SC68B, FCE17C37SC60B, FCE17C37SC61B, FCE17C37SC64B, FCE17C37SC65B, FCE17C37SC69B, FCE17C37SC6DB, and FCE17C37SC6EB represent the primary substitution path for the obsolete FCC17C37SC68B. All FCE17 variants maintain identical mechanical and electrical specifications with the following advantages:

Active product status with ongoing manufacturer support
RoHS Compliant certification (versus RoHS non-compliant original)
Enhanced dielectric material formulation (Thermoplastic, Glass Filled)
Identical current rating (5A), operating temperature range (-40°C ~ 85°C), and flammability rating (UL94 V-0)
Identical backset spacing (0.590" / 14.99mm) and board-side M3 flange configuration
Identical contact finish specifications (Gold, 15.0µin / 0.38µm thickness)
Identical contact material (Phosphor Bronze)
Identical features (Filter, Mounting Brackets)

The FCE17 series variants differ only in internal contact configuration or plating specifications not affecting mechanical or electrical compatibility. Selection among FCE17 variants should be based on specific application requirements and internal contact specifications.

HARTING Cross-Manufacturer Alternatives

The HARTING 09644147232 and 09664127600 connectors provide functional alternatives with enhanced electrical performance specifications:

09644147232 Characteristics:

Current rating: 7.5A (exceeds 5A requirement)
Operating temperature: -55°C ~ 125°C (exceeds -40°C ~ 85°C requirement)
Voltage rating: 100V (below 200V specification)
Flange feature: Housing/Shell (4-40) instead of Board Side (M3)
Backset spacing: 0.401" (10.20mm) versus 0.590" (14.99mm)
ROHS3 Compliant
Contact material: Copper Alloy (versus Phosphor Bronze)

09664127600 Characteristics:

Current rating: 6.5A (exceeds 5A requirement)
Operating temperature: -55°C ~ 125°C (exceeds -40°C ~ 85°C requirement)
Flange feature: Housing/Shell (Unthreaded) instead of Board Side (M3)
Backset spacing: 0.409" (10.40mm) versus 0.590" (14.99mm)
ROHS3 Compliant
Contact form: Stamped (versus Machined)
Contact material: Copper Alloy (versus Phosphor Bronze)

HARTING alternatives are suitable only when mechanical flange configuration and backset spacing differences are accommodated in the application design. The reduced backset spacing and alternative flange mounting require board layout verification.

Compliance Considerations

For applications requiring RoHS compliance, the FCE17 series is mandatory. The original FCC17C37SC68B is RoHS non-compliant. HARTING alternatives provide ROHS3 compliance as an additional option.

Frequently Asked Questions (FAQ)

Q: Can the FCE17C37SC68B directly replace the FCC17C37SC68B without design modification?

A: Yes. The FCE17C37SC68B maintains identical mechanical and electrical specifications including connector type, position count, shell size, mounting configuration, flange type, backset spacing, current rating, operating temperature range, and feature set. The primary difference is active product status and RoHS compliance. No design modification is required.

Q: What is the difference between the various FCE17 variants (SC60B, SC61B, SC64B, SC65B, SC69B, SC6DB, SC6EB)?

A: All FCE17 variants share identical mechanical and electrical specifications. Variant designations reflect differences in internal contact configuration or plating specifications not affecting mechanical or electrical compatibility with the original FCC17C37SC68B. Selection should be based on specific application requirements and internal contact specifications provided in detailed product documentation.

Q: Are the HARTING alternatives (09644147232 and 09664127600) direct mechanical replacements?

A: No. While HARTING alternatives maintain the same connector style, position count, and shell size, they differ in critical mechanical parameters. The backset spacing is reduced (0.401" or 0.409" versus 0.590"), and the flange configuration differs (Housing/Shell versus Board Side M3). These differences require board layout verification and potential mechanical redesign. Use HARTING alternatives only when mechanical accommodation is feasible.

Q: What is backset spacing and why does it matter?

A: Backset spacing is the distance from the rear of the connector shell to the mounting flange. The FCC17C37SC68B specifies 0.590" (14.99mm). This dimension determines the connector's position relative to the printed circuit board and affects component placement and board layout. Substitutes with different backset spacing require board redesign verification.

Q: Can I use a HARTING connector if my application requires 200V voltage rating?

A: The HARTING 09644147232 specifies 100V voltage rating, which is below the 200V requirement of the FCC17C37SC68B. The HARTING 09664127600 does not specify a voltage rating. For applications requiring 200V operation, use the Amphenol ICC FCE17 series, which maintains the 200V specification or use connectors with documented voltage ratings meeting or exceeding 200V.

Q: What does RoHS compliance mean and why is it important?

A: RoHS (Restriction of Hazardous Substances) compliance indicates the connector meets regulatory requirements restricting the use of specific hazardous materials including lead, cadmium, and mercury. The original FCC17C37SC68B is RoHS non-compliant. The FCE17 series is RoHS Compliant, and HARTING alternatives are ROHS3 Compliant. For applications subject to RoHS regulations or customer requirements, use compliant alternatives.

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

A: The FCC17C37SC68B packaging is not specified in the provided data. The HARTING alternatives are available in Bulk packaging. Amphenol ICC FCE17 variants do not specify packaging. Confirm packaging requirements and availability with the component supplier.

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

A: The FCC17C37SC68B uses Phosphor Bronze contacts, while HARTING alternatives use Copper Alloy contacts. Both materials provide electrical conductivity and mechanical durability suitable for signal applications. Phosphor Bronze offers specific spring characteristics and corrosion resistance properties. For applications with specific contact material requirements, use parts with matching contact material specifications.

Q: Can I substitute the FCC17C37SC68B with a different position count D-Sub connector?

A: No. The 37 position configuration is a critical specification. Substitutes must maintain the same position count (37), row configuration (2 rows), and shell size (4 / DC, C). Different position counts result in incompatible mating interfaces and are not acceptable substitutes.

Q: What is the significance of the UL94 V-0 flammability rating?

A: UL94 V-0 is a material flammability classification indicating the dielectric material meets stringent flame propagation requirements. All substitute parts maintain this rating, confirming compliance with fire safety standards applicable to the original component.
