Substitute Part Grouping Explanation

Substitution for the FCC17C37SC400 is determined by strict equivalence across the following critical parameters:

Primary Equivalence Criteria:

Connector type: Receptacle, Female Sockets
Position count: 37 positions in 2-row configuration
Shell size: 4 (DC, C)
Mounting: Through-hole, right-angle solder termination
Flange feature: Housing/Shell (4-40)
Contact type: Signal-level
Features: Board lock and filter functionality

Amphenol ICC FCE17 Series (Active Status): The FCE17C37SC400, FCE17C37SC410, FCE17C37SC440, FCE17C37SC450, FCE17C37SC480, FCE17C37SC490, FCE17C37SC4D0, and FCE17C37SC4E0 are direct parametric equivalents from the same manufacturer. These parts maintain identical mechanical dimensions, electrical ratings, and functional features. The primary distinction is product status (active vs. obsolete) and RoHS compliance (compliant vs. non-compliant). Dielectric material differs slightly (thermoplastic with glass fill vs. standard thermoplastic), and voltage rating is not specified for FCE17 variants.

HARTING Alternatives: The 09644147232 and 09664127600 from HARTING provide functional equivalence with notable parameter variations. These parts share the same connector style, position count, shell size, and mounting configuration. However, they differ in backset spacing, current rating, operating temperature range, contact material composition, and dielectric material formulation.

Engineering Selection Recommendations

Amphenol ICC FCE17 Series (Preferred Primary Substitutes): The FCE17C37SC400, FCE17C37SC410, FCE17C37SC440, FCE17C37SC450, FCE17C37SC480, FCE17C37SC490, FCE17C37SC4D0, and FCE17C37SC4E0 are the recommended substitutes for the obsolete FCC17C37SC400. These parts maintain identical mechanical and electrical specifications with the exception of RoHS compliance status. All FCE17 variants are active products with RoHS compliance, addressing the regulatory requirements that the original FCC17 part does not meet. The parametric differences between FCE17 variants (identified by the final two characters in the part number) relate to internal contact or assembly specifications not detailed in the provided parameters. Selection among FCE17 variants should be based on specific application requirements and availability.

HARTING Alternatives (Secondary Substitutes): The HARTING 09644147232 and 09664127600 provide functional equivalence for applications where the Amphenol ICC FCE17 series is unavailable. These parts maintain the same connector style, position count, shell size, and mounting configuration. However, they introduce the following parameter variations:

Backset spacing differs (0.401" or 0.409" versus 0.590"), which may affect PCB layout compatibility
Current rating is higher (6.5A to 7.5A versus 5A), providing additional capacity
Operating temperature range is extended (-55°C to 125°C versus -40°C to 85°C)
Contact material is copper alloy rather than phosphor bronze
Dielectric materials differ (PCT or PBT-based versus thermoplastic)

HARTING alternatives are suitable only when the mechanical and thermal specifications align with application requirements and when backset spacing differences can be accommodated in the design.

Frequently Asked Questions (FAQ)

Q: Can FCE17C37SC400 directly replace FCC17C37SC400 without design changes?

A: Yes. The FCE17C37SC400 maintains identical mechanical dimensions, electrical ratings, and functional features. The primary differences are product status (active versus obsolete) and RoHS compliance. No design modifications are required for direct substitution.

Q: What is the significance of the different FCE17 part number suffixes (SC410, SC440, SC450, SC480, SC490, SC4D0, SC4E0)?

A: The provided parameters do not specify the technical distinctions between these variants. Selection should be based on application-specific requirements and component availability. Consult the manufacturer's detailed specifications for internal assembly or contact configuration differences.

Q: Are HARTING parts mechanically compatible with the original FCC17C37SC400?

A: HARTING parts share the same connector style, position count, and shell size. However, backset spacing differs significantly (0.401" to 0.409" versus 0.590"), which affects PCB mounting hole placement. These parts are functionally equivalent but require PCB layout verification before implementation.

Q: What is the impact of the voltage rating difference between FCC17C37SC400 (200V) and FCE17 variants (not specified)?

A: The FCE17 series does not specify a voltage rating in the provided parameters. For applications requiring 200V rating confirmation, contact the manufacturer directly or consult detailed technical documentation.

Q: Are all substitute parts RoHS compliant?

A: The FCE17 series (all variants) and HARTING parts are RoHS compliant or ROHS3 compliant. The original FCC17C37SC400 is RoHS non-compliant. For applications subject to RoHS regulations, substitute parts must be selected from the compliant options.

Q: Can I use HARTING 09644147232 or 09664127600 in high-temperature applications?

A: Yes. HARTING parts operate across -55°C to 125°C, compared to the FCC17C37SC400 range of -40°C to 85°C. However, verify that other system components support the extended temperature range before implementation.

Q: What is the difference between the contact materials (Phosphor Bronze versus Copper Alloy)?

A: The provided parameters do not specify performance differences between these materials. Both are suitable for signal-level applications. For applications with specific contact resistance or durability requirements, consult the manufacturer's technical documentation.
