Frequently Asked Questions (FAQ)

Q: Can FCE17C37SC25B directly replace FCC17C37SC25B?

A: Yes. The FCE17C37SC25B is a direct parametric equivalent. All mechanical dimensions, electrical ratings, contact specifications, and termination methods are identical. The primary difference is product status (active versus obsolete) and RoHS compliance. No design modifications are required for substitution.

Q: What is the difference between the various FCE17 part numbers?

A: All FCE17 variants (FCE17C37SC20B, FCE17C37SC21B, FCE17C37SC24B, FCE17C37SC28B, FCE17C37SC29B, FCE17C37SC2DB, FCE17C37SC2EB) share identical electrical and mechanical specifications. The suffix designations reflect internal manufacturing or configuration variations not specified in the provided parameters. All are functionally interchangeable with the FCC17C37SC25B.

Q: Can HARTING parts replace the Amphenol ICC FCC17C37SC25B?

A: HARTING parts provide functional equivalence with parameter variations. The HARTING 09644147232 and 09664127600 differ in backset spacing, current rating, voltage rating, and operating temperature range. These parts are suitable only if the application requirements accommodate the specified parameter differences. Direct substitution without design review is not recommended.

Q: What is the significance of the backset spacing difference?

A: Backset spacing defines the distance from the rear of the connector shell to the solder cup termination points. The FCC17C37SC25B specifies 0.590" (14.99mm). HARTING alternatives specify 0.401" (10.20mm) and 0.409" (10.40mm) respectively. This parameter affects PCB layout and mounting clearance. Substitution requires verification that the printed circuit board design accommodates the alternative backset spacing.

Q: Are all substitute parts RoHS compliant?

A: The FCC17C37SC25B is RoHS non-compliant. All Amphenol ICC FCE17 variants are RoHS compliant. HARTING parts are ROHS3 compliant. If RoHS compliance is a design requirement, the FCC17C37SC25B must be replaced with an FCE17 variant or HARTING equivalent.

Q: What is the voltage rating difference between parts?

A: The FCC17C37SC25B specifies 200V. Amphenol ICC FCE17 variants do not specify a voltage rating in the provided parameters. HARTING 09644147232 specifies 100V. HARTING 09664127600 does not specify a voltage rating. If the application requires 200V rating, the FCC17C37SC25B or FCE17 variants are appropriate. HARTING 09644147232 is limited to 100V applications.

Q: What is the operating temperature range difference?

A: The FCC17C37SC25B operates from -40°C to 85°C. All Amphenol ICC FCE17 variants maintain this range. HARTING parts extend the operating range to -55°C to 125°C. If the application requires operation below -40°C or above 85°C, HARTING alternatives provide extended thermal capability.

Q: What is the current rating difference?

A: The FCC17C37SC25B is rated for 5A. Amphenol ICC FCE17 variants maintain 5A rating. HARTING 09644147232 is rated for 7.5A. HARTING 09664127600 is rated for 6.5A. If the application requires current capacity exceeding 5A, HARTING alternatives provide elevated ratings.

Q: Are there inventory considerations for part selection?

A: Inventory levels are provided for reference. FCC17C37SC25B has 731 units in stock. FCE17C37SC25B has 736 units. FCE17C37SC24B has the highest FCE17 inventory at 959 units. HARTING 09664127600 has 930 units. HARTING 09644147232 has 715 units. Availability should be confirmed with the component supplier for production requirements.
