Engineering Selection Recommendations

Amphenol ICC FCE17 Series (Direct Equivalents)

The FCE17B25SC4EB, FCE17B25SC40B, FCE17B25SC41B, FCE17B25SC44B, FCE17B25SC45B, FCE17B25SC48B, FCE17B25SC49B, and FCE17B25SC4DB represent the primary substitution path for the obsolete FCC17B25SC4EB. All FCE17 variants maintain identical mechanical and electrical specifications with the exception of dielectric material composition (thermoplastic with glass filling in FCE17 series versus standard thermoplastic in FCC17). All FCE17 parts carry active product status and RoHS compliance certification, addressing regulatory requirements that the original part does not satisfy.

HARTING 09663126600 and 09663126601 (Alternative Manufacturers)

The HARTING connectors 09663126600 and 09663126601 provide functional alternatives with the following distinctions: both maintain 25 position, 2 row, DB/B shell size configuration with through-hole right-angle solder termination. The HARTING parts feature higher current rating (6.5A versus 5A), extended operating temperature range (-55°C to 125°C versus -40°C to 85°C), and ROHS3 compliance. Backset spacing differs at 0.409" (10.40mm) compared to 0.590" (14.99mm) in the primary part. Contact finish specifications are not provided for HARTING parts. Flange features differ: 09663126600 uses unthreaded housing/shell mounting, while 09663126601 uses M3 threaded mounting, both distinct from the 4-40 board-side flange of the FCC17B25SC4EB.

Selection Basis

For applications requiring direct form-fit-function replacement with maintained electrical specifications and RoHS compliance, the Amphenol ICC FCE17 series is the appropriate selection. For applications requiring extended temperature performance or higher current capacity, HARTING alternatives provide enhanced specifications, contingent upon PCB layout accommodation of the different backset spacing and flange mounting configuration.

Frequently Asked Questions (FAQ)

Q: Can FCE17B25SC4EB directly replace FCC17B25SC4EB without PCB modification?

A: Yes. The FCE17B25SC4EB maintains identical mechanical dimensions, mounting configuration, and electrical ratings. The primary difference is dielectric material composition and RoHS compliance status. No PCB layout changes are required.

Q: What is the significance of the different FCE17 part number suffixes (SC40B, SC41B, SC44B, SC45B, SC48B, SC49B, SC4DB)?

A: The provided data does not specify the technical distinctions between these suffix variations. All variants maintain identical parameters across connector style, position count, shell size, mounting type, termination method, current rating, voltage rating, operating temperature, and flammability rating. Selection among these variants should be based on specific application requirements not detailed in the provided parameter set.

Q: Are HARTING parts 09663126600 and 09663126601 interchangeable with each other?

A: Both HARTING parts share identical electrical and mechanical specifications with one exception: flange feature configuration. Part 09663126600 uses unthreaded housing/shell mounting, while 09663126601 uses M3 threaded mounting. Selection depends on the specific mounting requirement of the application.

Q: What is the impact of the different backset spacing in HARTING connectors?

A: HARTING parts feature 0.409" (10.40mm) backset spacing compared to 0.590" (14.99mm) in the Amphenol ICC parts. Backset spacing determines the distance from the connector mounting surface to the contact plane. This difference requires PCB layout verification to ensure proper mating with corresponding plug connectors and adequate clearance for adjacent components.

Q: Do the HARTING connectors meet the same flammability standards?

A: Yes. Both HARTING parts 09663126600 and 09663126601 carry UL94 V-0 material flammability rating, identical to the original FCC17B25SC4EB and all Amphenol ICC FCE17 variants.

Q: What is the difference between RoHS compliance and ROHS3 compliance?

A: The provided data indicates FCC17B25SC4EB as RoHS non-compliant, FCE17 series parts as RoHS Compliant, and HARTING parts as ROHS3 Compliant. The specific technical distinctions between these compliance levels are not detailed in the provided parameter set. Compliance verification should be conducted against applicable regulatory requirements for the target application and market.

Q: Can the higher current rating of HARTING connectors (6.5A vs 5A) be utilized in applications designed for 5A?

A: Yes. A component rated for higher current capacity can be used in applications requiring lower current. The 6.5A rating of HARTING connectors provides additional margin in applications designed for 5A operation.

Q: What is the significance of the extended operating temperature range in HARTING connectors?

A: HARTING parts operate across -55°C to 125°C compared to -40°C to 85°C for Amphenol ICC parts. Applications requiring operation at temperatures below -40°C or above 85°C require HARTING connectors or equivalent alternatives with extended temperature specifications.

Q: Is contact finish specification critical for connector selection?

A: Contact finish affects electrical performance, corrosion resistance, and mating force characteristics. The FCC17B25SC4EB and all Amphenol ICC FCE17 variants specify gold contact finish at 15.0µin (0.38µm) thickness. HARTING parts do not provide contact finish specifications in the available data. Contact finish compatibility should be verified when selecting alternative manufacturers.
