Engineering Selection Recommendations

Amphenol ICC FCE17 Series (Direct Equivalents):

The FCE17C37SC28B, FCE17C37SC20B, FCE17C37SC21B, FCE17C37SC24B, FCE17C37SC25B, FCE17C37SC29B, FCE17C37SC2DB, and FCE17C37SC2EB connectors are active products from Amphenol ICC that maintain electrical and mechanical compatibility with the obsolete FCC17C37SC28B. All FCE17 variants are RoHS compliant, addressing regulatory requirements that the original FCC17 series does not meet. These parts share identical connector geometry, pin configuration, current rating, operating temperature range, and termination method. The FCE17 series represents the direct product line evolution from the FCC17 series.

HARTING Alternatives:

The HARTING 09644147232 and 09664127600 connectors provide functional alternatives with the following considerations:

The 09644147232 operates at 7.5A current rating and 100V voltage rating, exceeding the FCC17C37SC28B specifications. Operating temperature extends to -55°C ~ 125°C. This part features board lock and filter capabilities with a different backset spacing (0.401" versus 0.590").

The 09664127600 operates at 6.5A current rating with unspecified voltage rating and extended operating temperature range (-55°C ~ 125°C). Backset spacing is 0.409" versus the original 0.590".

Both HARTING alternatives are ROHS3 compliant and carry REACH unaffected status. Selection of HARTING alternatives requires mechanical validation due to backset spacing differences.

Frequently Asked Questions (FAQ)

Q: Can FCE17C37SC28B directly replace FCC17C37SC28B in existing designs?

A: Yes. The FCE17C37SC28B maintains identical electrical specifications (5A current rating, -40°C ~ 85°C operating temperature), mechanical configuration (37 positions, 2 rows, right-angle through-hole mounting), and contact geometry (gold plating, 15.0µin thickness). The primary difference is RoHS compliance status. Physical footprint and pin assignment are equivalent.

Q: What is the difference between the various FCE17 part numbers (SC20B, SC21B, SC24B, SC25B, SC29B, SC2DB, SC2EB)?

A: The FCE17 series variants differ in internal dielectric material formulations and contact material specifications. All variants maintain identical external dimensions, pin counts, current ratings, and operating temperature ranges. Selection among FCE17 variants depends on specific application requirements not detailed in the provided parameters. Consult detailed datasheets for material composition differences.

Q: Are HARTING connectors mechanically compatible with the FCC17C37SC28B footprint?

A: HARTING connectors maintain 37-position D-Sub configuration with right-angle through-hole mounting. However, backset spacing differs: HARTING 09644147232 specifies 0.401" (10.20mm) and 09664127600 specifies 0.409" (10.40mm), compared to the FCC17C37SC28B backset of 0.590" (14.99mm). This spacing difference affects PCB layout compatibility. Mechanical validation is required before substitution.

Q: What is the significance of RoHS compliance for this connector?

A: The FCC17C37SC28B is RoHS non-compliant, while all FCE17 variants and HARTING alternatives are RoHS compliant. RoHS compliance restricts hazardous substances in electrical and electronic equipment. For applications subject to RoHS regulations or customer requirements, FCE17 series substitution is necessary.

Q: Can I use a HARTING connector if my design requires 200V rating?

A: The HARTING 09644147232 specifies 100V voltage rating, which is below the FCC17C37SC28B 200V rating. The HARTING 09664127600 does not specify a voltage rating. For applications requiring 200V operation, Amphenol ICC FCE17 series alternatives are recommended, as voltage specifications are not provided in the available data but the series maintains compatibility with the original design envelope.

Q: What inventory levels are available for each substitute part?

A: Current inventory levels are: FCE17C37SC28B (927 pcs), FCE17C37SC20B (867 pcs), FCE17C37SC21B (820 pcs), FCE17C37SC24B (959 pcs), FCE17C37SC25B (736 pcs), FCE17C37SC29B (850 pcs), FCE17C37SC2DB (806 pcs), FCE17C37SC2EB (875 pcs), HARTING 09644147232 (715 pcs), and HARTING 09664127600 (930 pcs). Inventory levels are subject to change and should be confirmed with suppliers.

Q: Are there any certifications or compliance differences between substitute options?

A: FCC17C37SC28B carries UL94 V-0 flammability rating and EAR99 ECCN classification. All FCE17 variants maintain UL94 V-0 rating and EAR99 classification with added RoHS compliance. HARTING alternatives carry UL94 V-0 rating, ROHS3 compliance, REACH unaffected status, EAR99 ECCN, and identical HTSUS classification. Compliance requirements for your application determine the appropriate substitute selection.
