Substitute parts are grouped into two categories:

Category 1: Direct Amphenol ICC Equivalents (FCE17 Series) These parts maintain identical electrical and mechanical specifications to the FCC17B25SC48B while offering active product status and RoHS compliance. The FCE17 series represents the active production equivalent to the obsolete FCC17 series. Variations within this group (FCE17B25SC40B, FCE17B25SC41B, FCE17B25SC44B, FCE17B25SC45B, FCE17B25SC49B, FCE17B25SC4DB, FCE17B25SC4EB) differ only in contact form specification and dielectric material composition (Thermoplastic, Glass Filled versus standard Thermoplastic), which do not affect functional interchangeability for standard applications.

Category 2: Cross-Manufacturer Alternatives (HARTING) The HARTING parts 09663126600 and 09663126601 provide functional equivalence with notable parameter variations. These connectors maintain the same connector style, type, position count, row configuration, shell size, mounting type, and termination method. However, they differ in backset spacing (0.409" versus 0.590"), current rating (6.5A versus 5A), contact form (Stamped versus Machined), flange feature configuration, and operating temperature range (-55°C ~ 125°C versus -40°C ~ 85°C). These differences require application-level verification before substitution.

Engineering Selection Recommendations

Primary Recommendation: Amphenol ICC FCE17 Series

The FCE17B25SC48B, FCE17B25SC40B, FCE17B25SC41B, FCE17B25SC44B, FCE17B25SC45B, FCE17B25SC49B, FCE17B25SC4DB, and FCE17B25SC4EB represent the direct active production equivalents to the obsolete FCC17B25SC48B. These parts maintain identical electrical and mechanical specifications while offering active product status and RoHS compliance. Selection among these variants should be based on specific application requirements regarding contact form specification and dielectric material composition. All FCE17 variants are manufactured by Amphenol ICC and provide full functional interchangeability with the original FCC17B25SC48B.

Secondary Recommendation: HARTING Cross-Manufacturer Alternatives

The HARTING parts 09663126600 and 09663126601 provide functional equivalence for applications where backset spacing tolerance, flange feature configuration, and extended operating temperature range are acceptable. These connectors offer higher current rating (6.5A) and wider operating temperature range (-55°C ~ 125°C) compared to the original specification. However, the reduced backset spacing (0.409" versus 0.590") and different flange feature configuration (Housing/Shell versus Board Side 4-40) require verification against specific PCB layout and mechanical mounting requirements before implementation.

Compliance Considerations

The FCC17B25SC48B is RoHS non-compliant. All Amphenol ICC FCE17 series substitutes are RoHS compliant, supporting regulatory requirements for new designs and updated production. The HARTING alternatives are ROHS3 compliant. Selection of substitute parts should align with applicable regulatory and compliance requirements for the target application.

Frequently Asked Questions (FAQ)

Q: Can the FCE17B25SC48B be used as a direct replacement for the FCC17B25SC48B?

A: Yes. The FCE17B25SC48B maintains identical electrical and mechanical specifications to the FCC17B25SC48B. The primary differences are active product status and RoHS compliance. The FCE17 series represents the active production equivalent to the obsolete FCC17 series.

Q: What is the difference between the various FCE17B25SC variants?

A: The FCE17B25SC variants (SC40B, SC41B, SC44B, SC45B, SC49B, SC4DB, SC4EB) differ in contact form specification and dielectric material composition. All variants maintain the same electrical and mechanical specifications, including 25 positions, 2 rows, 0.590" backset spacing, 5A current rating, and board-side 4-40 flange mounting. Selection among variants should be based on specific application requirements.

Q: Can HARTING parts 09663126600 or 09663126601 be used as direct replacements?

A: HARTING parts provide functional equivalence with notable parameter variations. The backset spacing differs (0.409" versus 0.590"), flange feature configuration differs (Housing/Shell versus Board Side 4-40), and operating temperature range is extended (-55°C ~ 125°C versus -40°C ~ 85°C). These differences require application-level verification before substitution. PCB layout and mechanical mounting requirements must be confirmed to ensure compatibility.

Q: What is the significance of the backset spacing difference between Amphenol ICC and HARTING parts?

A: Backset spacing defines the distance from the mounting flange to the rear of the connector shell. The FCC17B25SC48B and all FCE17 variants specify 0.590" (14.99mm) backset spacing, while HARTING parts specify 0.409" (10.40mm). This difference affects PCB layout and mechanical clearance requirements. Substitution requires verification that the target PCB and mechanical assembly accommodate the different backset spacing.

Q: What is the difference between board-side 4-40 flange and housing/shell flange features?

A: Board-side 4-40 flange mounting uses threaded 4-40 holes on the PCB for mechanical attachment. Housing/shell flange mounting (unthreaded or M3) uses different mechanical attachment methods. The FCC17B25SC48B and all FCE17 variants use board-side 4-40 mounting. HARTING parts use housing/shell mounting. Substitution requires verification that the target PCB and mechanical assembly support the different flange feature configuration.

Q: Are there packaging differences among the substitute parts?

A: The FCE17B25SC49B is specified with Box packaging, while most other variants do not specify packaging type. Packaging differences do not affect functional interchangeability but may impact procurement, storage, and handling requirements.

Q: What is the significance of RoHS compliance for substitute part selection?

A: The FCC17B25SC48B is RoHS non-compliant. All Amphenol ICC FCE17 series substitutes are RoHS compliant, and HARTING alternatives are ROHS3 compliant. RoHS compliance is required for many applications and regulatory jurisdictions. Selection of RoHS-compliant substitutes supports compliance with applicable environmental and regulatory requirements.

Q: How do contact material differences affect substitution?

A: The FCC17B25SC48B uses phosphor bronze contacts, as do all FCE17 variants. HARTING parts use copper alloy contacts. Contact material affects electrical conductivity, corrosion resistance, and mechanical durability. Phosphor bronze and copper alloy contacts are both suitable for standard signal applications. Substitution does not require contact material change for typical applications.

Q: What is the significance of the dielectric material difference between FCC17 and FCE17 series?

A: The FCC17B25SC48B uses standard thermoplastic dielectric material. FCE17 variants use thermoplastic with glass filling. Glass-filled thermoplastic provides improved mechanical strength and thermal stability. This difference does not affect functional interchangeability for standard applications but may provide improved performance in demanding mechanical or thermal environments.
