Engineering Selection Recommendations

Amphenol ICC FCE17 Series (FCE17B25SC450, FCE17B25SC400, FCE17B25SC410, FCE17B25SC440, FCE17B25SC480, FCE17B25SC490, FCE17B25SC4D0, FCE17B25SC4E0)

The FCE17 series represents the direct successor platform to the obsolete FCC17B25SC450. All FCE17 variants maintain identical mechanical and electrical specifications including 25-position configuration, through-hole right-angle mounting, solder termination, and 5A current rating. The primary distinction is RoHS compliance status: FCE17 series parts are RoHS Compliant, whereas the FCC17B25SC450 is RoHS non-compliant. All FCE17 variants carry active product status, ensuring ongoing availability and manufacturing support. The FCE17 series incorporates thermoplastic glass-filled dielectric material compared to the standard thermoplastic of the original part. These connectors are suitable for direct substitution in new designs and legacy system maintenance where RoHS compliance is required or preferred.

HARTING 09663126600 and 09663126601

The HARTING alternatives provide equivalent D-Sub 25-position receptacle functionality with ROHS3 compliance. These parts differ in backset spacing (0.409" versus 0.590"), flange feature configuration (unthreaded housing or M3 threaded versus 4-40 threaded), and contact material (copper alloy versus phosphor bronze). HARTING parts offer higher current rating (6.5A versus 5A) and extended operating temperature range (-55°C to 125°C versus -40°C to 85°C). These specifications indicate suitability for applications requiring enhanced thermal performance or higher current capacity. The different backset spacing and flange mounting options necessitate mechanical design review prior to substitution.

Compliance Considerations

Selection between FCC17B25SC450 and substitute parts should account for regulatory requirements. Legacy systems operating under non-RoHS environments may continue using the original FCC17B25SC450 where inventory permits. New production and systems subject to RoHS directives require FCE17 series or HARTING alternatives. HARTING ROHS3 compliance provides the highest regulatory alignment for current and future applications.

Frequently Asked Questions (FAQ)

Q: Can FCE17B25SC450 directly replace FCC17B25SC450 in existing designs?

A: Yes. The FCE17B25SC450 maintains identical mechanical and electrical specifications including connector style, position count, mounting type, termination method, current rating, and operating temperature range. The primary difference is RoHS compliance status and dielectric material composition (glass-filled thermoplastic versus standard thermoplastic). Direct substitution is mechanically and electrically compatible.

Q: What distinguishes the multiple FCE17B25SC4XX variants?

A: The FCE17B25SC400, FCE17B25SC410, FCE17B25SC440, FCE17B25SC480, FCE17B25SC490, FCE17B25SC4D0, and FCE17B25SC4E0 variants share identical mechanical and electrical specifications. The alphanumeric suffix designates internal configuration or manufacturing process variations not reflected in the provided electrical and mechanical parameters. All variants are electrically and mechanically interchangeable for the specified 25-position D-Sub receptacle application.

Q: Are HARTING 09663126600 and 09663126601 suitable substitutes?

A: HARTING parts provide equivalent D-Sub 25-position receptacle functionality with active product status and ROHS3 compliance. However, mechanical differences exist: backset spacing is 0.409" (versus 0.590"), flange mounting differs (unthreaded housing or M3 threaded versus 4-40 threaded), and contact material is copper alloy (versus phosphor bronze). These differences require mechanical design verification before substitution. HARTING parts are suitable for applications where the different backset spacing and flange configuration are compatible with the PCB layout and mounting structure.

Q: What is the significance of backset spacing differences?

A: Backset spacing defines the distance from the connector mounting face to the contact plane. The FCC17B25SC450 and all FCE17 variants specify 0.590" (14.99mm) backset spacing. HARTING alternatives specify 0.409" (10.40mm). This difference affects PCB layout, mating connector alignment, and overall assembly geometry. Substitution of HARTING parts requires verification that the reduced backset spacing is compatible with the existing PCB design and mating connector configuration.

Q: How do flange feature differences impact substitution?

A: The FCC17B25SC450 features a 4-40 threaded housing/shell flange. HARTING 09663126600 provides an unthreaded housing/shell flange, while 09663126601 provides an M3 threaded flange. These differences affect mounting method and mechanical fastening. Substitution requires confirmation that the alternative flange configuration is compatible with the existing mounting structure and fastening hardware.

Q: What is the impact of contact material differences?

A: The FCC17B25SC450 and all FCE17 variants use phosphor bronze contacts. HARTING alternatives use copper alloy contacts. Both materials provide adequate electrical conductivity and mechanical durability for signal-level applications. Phosphor bronze offers superior spring characteristics and wear resistance in high-cycle mating applications. Copper alloy provides cost efficiency and adequate performance for standard signal applications. Material selection does not impact electrical compatibility for standard signal transmission.

Q: Does the higher current rating of HARTING parts affect compatibility?

A: HARTING parts are rated for 6.5A versus the 5A rating of the FCC17B25SC450 and FCE17 variants. Higher current rating indicates enhanced current-carrying capacity and does not create compatibility issues. Applications operating at or below 5A are fully compatible with HARTING parts. The higher rating provides additional design margin for applications approaching the 5A limit.

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

A: HARTING parts operate across -55°C to 125°C, compared to -40°C to 85°C for the FCC17B25SC450 and FCE17 variants. Extended temperature range indicates suitability for applications subject to extreme thermal environments. Applications operating within the -40°C to 85°C range are fully compatible with HARTING parts. The extended range provides additional design margin for applications approaching temperature limits.

Q: Are there inventory considerations for substitute part selection?

A: Current inventory levels are provided for reference: FCC17B25SC450 (1088 pcs), FCE17B25SC450 (1049 pcs), FCE17B25SC400 (987 pcs), FCE17B25SC410 (726 pcs), FCE17B25SC440 (960 pcs), FCE17B25SC480 (865 pcs), FCE17B25SC490 (668 pcs), FCE17B25SC4D0 (1089 pcs), FCE17B25SC4E0 (1083 pcs), 09663126600 (734 pcs), and 09663126601 (1073 pcs). Inventory levels support component selection based on availability and delivery requirements.

Q: What compliance certifications apply to each substitute option?

A: FCC17B25SC450 is RoHS non-compliant. All FCE17 variants are RoHS Compliant. HARTING 09663126600 and 09663126601 are ROHS3 Compliant. Applications subject to RoHS directives require FCE17 series or HARTING alternatives. ROHS3 compliance provides alignment with current regulatory requirements and future compliance trajectories.
