Amphenol ICC FCE17 Series parts (FCE17B25SC29B, FCE17B25SC20B, FCE17B25SC21B, FCE17B25SC24B, FCE17B25SC25B, FCE17B25SC28B, FCE17B25SC2DB, FCE17B25SC2EB) meet all primary substitution criteria. These parts are active products with RoHS compliance, offering improved availability compared to the obsolete FCC17B25SC29B.

HARTING parts (09663126600, 09663126601) share the core D-Sub 25 position receptacle configuration but exhibit variations in backset spacing (0.409" vs. 0.590"), contact form (stamped vs. machined), and operating temperature range (-55°C ~ 125°C vs. -40°C ~ 85°C). These differences require engineering evaluation for specific applications.

Engineering Selection Recommendations

Primary Recommendation: Amphenol ICC FCE17 Series

The FCE17B25SC29B, FCE17B25SC20B, FCE17B25SC21B, FCE17B25SC24B, FCE17B25SC25B, FCE17B25SC28B, FCE17B25SC2DB, and FCE17B25SC2EB connectors are direct functional equivalents to the obsolete FCC17B25SC29B. All FCE17 variants maintain identical electrical and mechanical specifications across the critical parameters: 25 positions, 2 rows, shell size 3 (DB, B), through-hole right-angle mounting, solder termination, gold-plated contacts at 15.0µin thickness, 5A current rating, and -40°C to 85°C operating temperature range.

The FCE17 series offers the advantage of active product status with RoHS compliance, ensuring long-term availability and regulatory alignment. These parts are suitable for direct substitution in applications where the original FCC17B25SC29B was specified.

Secondary Consideration: HARTING 09663126600 and 09663126601

The HARTING connectors share the D-Sub 25 position receptacle configuration and through-hole right-angle solder termination. However, these parts exhibit material and dimensional differences that require engineering evaluation:

Backset spacing differs (0.409" vs. 0.590"), affecting PCB layout compatibility
Contact material is copper alloy rather than phosphor bronze
Operating temperature range extends to -55°C and 125°C, exceeding the original specification
Current rating is 6.5A, higher than the original 5A specification
Contact finish specifications are not provided

The HARTING parts are suitable only for applications where the dimensional and material variations are acceptable and where the extended operating temperature range provides benefit.

Frequently Asked Questions (FAQ)

Q: Can FCE17B25SC29B directly replace FCC17B25SC29B?

A: Yes. The FCE17B25SC29B is a direct functional equivalent. Both connectors share identical specifications for connector type, position count, shell size, mounting configuration, termination method, contact finish, current rating, and operating temperature range. The primary difference is product status: FCE17B25SC29B is active with RoHS compliance, while FCC17B25SC29B is obsolete.

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

A: The FCE17B25SC20B, FCE17B25SC21B, FCE17B25SC24B, FCE17B25SC25B, FCE17B25SC28B, FCE17B25SC2DB, and FCE17B25SC2EB variants maintain identical electrical and mechanical specifications. The suffix designations (20B, 21B, 24B, 25B, 28B, 2DB, 2EB) reflect internal design or manufacturing variations that do not affect functional compatibility. All variants are suitable for substitution.

Q: Are HARTING connectors compatible with FCC17B25SC29B?

A: HARTING 09663126600 and 09663126601 share the D-Sub 25 position receptacle configuration but differ in critical parameters. The backset spacing is 0.409" compared to 0.590" in the original part, which affects PCB mounting hole placement. Contact material is copper alloy rather than phosphor bronze. These differences require engineering evaluation for specific applications. Direct substitution is not recommended without design verification.

Q: What does backset spacing mean?

A: Backset spacing is the distance from the rear of the connector shell to the center of the solder cup or contact termination point. This dimension is critical for PCB layout design. The FCC17B25SC29B and all FCE17 variants have 0.590" (14.99mm) backset spacing, while HARTING parts have 0.409" (10.40mm). Mismatched backset spacing requires PCB redesign.

Q: Is RoHS compliance important for my application?

A: RoHS compliance status depends on your application requirements and regulatory jurisdiction. The FCE17 series connectors are RoHS compliant, while the original FCC17B25SC29B is non-compliant. If your application or market requires RoHS compliance, FCE17 variants are the appropriate choice. HARTING parts are ROHS3 compliant.

Q: Can I use a HARTING connector if my PCB is already designed for FCC17B25SC29B?

A: Not without PCB modification. The HARTING connectors have different backset spacing (0.409" vs. 0.590"), requiring relocation of mounting holes and solder pads. Additionally, the contact material and finish specifications differ. PCB redesign and electrical testing are necessary before substitution.

Q: What is the current rating difference between FCC17B25SC29B and HARTING parts?

A: The FCC17B25SC29B and all FCE17 variants are rated for 5A continuous current. HARTING 09663126600 and 09663126601 are rated for 6.5A. The higher HARTING rating does not affect compatibility for applications designed for 5A operation, but the different contact material (copper alloy vs. phosphor bronze) and unspecified contact finish may affect electrical performance characteristics.

Q: Are there inventory considerations for selecting a substitute?

A: Yes. Current inventory levels vary across available parts. FCE17B25SC2DB has the highest inventory (1123 pcs), while FCE17B25SC28B and FCE17B25SC2EB have lower levels (734 and 738 pcs respectively). For high-volume requirements, inventory availability should be confirmed with the supplier. All FCE17 variants are active products with ongoing manufacturing support.

Q: What is the operating temperature range difference?

A: The FCC17B25SC29B and all FCE17 variants operate from -40°C to 85°C. HARTING 09663126600 and 09663126601 operate from -55°C to 125°C. The extended HARTING range is beneficial for extreme environment applications but is not required for standard industrial applications within the original temperature specification.
