Frequently Asked Questions (FAQ)

Q: Can FCE17C37SB48B directly replace FCC17C37SB48B in existing designs?

A: Yes. The FCE17C37SB48B is a direct parametric equivalent with identical electrical and mechanical specifications. The primary difference is product status (active vs. obsolete) and RoHS compliance. No design modifications are required for substitution.

Q: What is the difference between the various FCE17C37SB variants?

A: The FCE17C37SB40B, FCE17C37SB41B, FCE17C37SB44B, FCE17C37SB45B, FCE17C37SB49B, FCE17C37SB4DB, and FCE17C37SB4EB variants maintain identical external specifications and are functionally equivalent. Differences exist in internal design parameters not provided in the specification data. All variants are suitable substitutes for the FCC17C37SB48B.

Q: Are HARTING connectors compatible with Amphenol ICC FCC17/FCE17 series?

A: HARTING 09644147232 and 09664127600 are mechanically and functionally similar D-Sub 37 position receptacles. However, they contain parameter variations in backset spacing, current rating, voltage rating, contact material, and operating temperature range. Compatibility depends on whether these variations are acceptable for the specific application. Physical fit and electrical performance must be evaluated against application requirements.

Q: What is the significance of backset spacing differences?

A: Backset spacing (0.401", 0.405", 0.409") defines the distance from the connector mounting surface to the rear of the connector body. Variations of ±0.004" may affect board layout, component clearance, and mechanical fit. Applications with tight spatial constraints should verify compatibility before substitution.

Q: Why is RoHS compliance important for this substitution?

A: RoHS compliance indicates the connector meets Restriction of Hazardous Substances regulations. The FCC17C37SB48B is RoHS non-compliant, while all FCE17 variants are RoHS compliant. For applications subject to RoHS requirements, FCE17 series parts are mandatory. HARTING parts are ROHS3 compliant, meeting current regulatory standards.

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

A: HARTING 09644147232 is rated for 100V maximum, which is below the FCC17C37SB48B specification of 200V. HARTING 09664127600 does not specify a voltage rating. For applications requiring 200V operation, Amphenol ICC FCE17 series parts are the appropriate choice.

Q: What is the impact of contact material differences?

A: FCC17C37SB48B and FCE17 series use phosphor bronze contacts with gold finish. HARTING parts use copper alloy contacts. Phosphor bronze provides superior corrosion resistance and contact reliability. For applications requiring maximum contact durability and signal integrity, phosphor bronze contacts are preferred. Copper alloy contacts are suitable for general-purpose applications with standard environmental conditions.

Q: Are there inventory considerations for substitution?

A: Current inventory levels are: FCC17C37SB48B (1113 pcs), FCE17C37SB48B (714 pcs), FCE17C37SB40B (854 pcs), FCE17C37SB41B (938 pcs), FCE17C37SB44B (1052 pcs), FCE17C37SB45B (1148 pcs), FCE17C37SB49B (1048 pcs), FCE17C37SB4DB (1040 pcs), FCE17C37SB4EB (942 pcs), HARTING 09644147232 (715 pcs), HARTING 09664127600 (930 pcs). All substitute parts maintain adequate stock levels for procurement.
