Secondary Recommendation: HARTING 09654226800 and 09654227800

The HARTING connectors 09654226800 and 09654227800 provide functional substitution for applications where parameter variations are acceptable. These parts are suitable when:

Extended operating temperature range (-55°C ~ 125°C) is required beyond the standard -40°C ~ 85°C specification. Increased current capacity (6.5A versus 5A) provides additional design margin. ROHS3 compliance is required. Unthreaded flange mounting is compatible with the application design.

The HARTING parts introduce the following parameter differences: backset spacing of 0.409" (10.40mm) versus 0.405" (10.29mm), stamped contact form versus machined, copper alloy contact material versus phosphor bronze, and polybutylene terephthalate (PBT), polyester, glass filled dielectric versus thermoplastic. These differences require verification of mechanical fit and electrical performance in the specific application circuit.

Frequently Asked Questions (FAQ)

Q: Can the FCE17C37PB400 directly replace the FCC17C37PB400 without design modifications?

A: Yes. The FCE17C37PB400 maintains identical electrical and mechanical specifications across all critical parameters: 37-position D-Sub plug configuration, male pins, right-angle through-hole solder termination, 5A current rating, 200V voltage rating, -40°C ~ 85°C operating temperature, steel tin-plated shell, gold-plated phosphor bronze contacts, UL94 V-0 flammability rating, and 0.405" (10.29mm) backset spacing. The primary difference is active product status and RoHS compliance. No circuit or mechanical design changes are required.

Q: What distinguishes the different FCE17C37 part number variants (PB400, PB410, PB440, PB450, PB480, PB490, PB4D0, PB4E0)?

A: The final two characters of the part number indicate internal configuration variants within the FCE17C37 series. All variants maintain identical external electrical and mechanical parameters, including connector type, position count, shell size, mounting style, termination method, current rating, operating temperature range, and contact specifications. The variants differ in internal design features not specified in the provided parameters. Selection among these variants depends on specific application requirements and internal configuration compatibility.

Q: Are the HARTING 09654226800 and 09654227800 connectors fully compatible with the FCC17C37PB400?

A: The HARTING connectors provide functional substitution with parameter variations that require application-specific verification. Mechanical compatibility must be confirmed for the following differences: backset spacing of 0.409" (10.40mm) versus 0.405" (10.29mm) may affect printed circuit board layout and connector positioning; unthreaded flange versus 4-40 threaded flange requires different mounting hardware; stamped contact form versus machined contacts may affect contact resistance and durability characteristics. Electrical performance is compatible for applications operating within the extended temperature range (-55°C ~ 125°C) and increased current capacity (6.5A). Verification testing is required before production implementation.

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

A: The FCC17C37PB400 is RoHS non-compliant, while all substitute parts (FCE17 series and HARTING) are RoHS compliant or ROHS3 compliant. RoHS compliance restricts the use of hazardous substances including lead, cadmium, mercury, hexavalent chromium, polybrominated biphenyls, and polybrominated diphenyl ethers. For new designs and manufacturing in regulated markets (European Union, California, and other jurisdictions), RoHS-compliant substitutes are mandatory. For legacy system repairs and maintenance where RoHS compliance is not required, the original FCC17C37PB400 remains functionally equivalent if available inventory permits.

Q: How do the contact material differences between phosphor bronze and copper alloy affect connector performance?

A: The FCC17C37PB400 and all FCE17 series substitutes use phosphor bronze contacts, while HARTING 09654226800 and 09654227800 use copper alloy contacts. Phosphor bronze provides superior spring properties, fatigue resistance, and contact reliability over extended mating cycles. Copper alloy contacts offer lower cost and adequate performance for standard applications. Both materials are suitable for signal-level applications at 5A current rating. Contact resistance and durability characteristics differ between materials; applications requiring high reliability or extended mating cycle life should prioritize phosphor bronze contacts.

Q: What inventory considerations apply to substitute part selection?

A: Current inventory levels are: FCC17C37PB400 (953 units, obsolete status); FCE17C37PB400 (1123 units); FCE17C37PB410 (909 units); FCE17C37PB440 (966 units); FCE17C37PB450 (822 units); FCE17C37PB480 (886 units); FCE17C37PB490 (915 units); FCE17C37PB4D0 (943 units); FCE17C37PB4E0 (719 units); 09654226800 (1047 units); 09654227800 (822 units). The FCE17C37PB400 offers the highest inventory level (1123 units) among active substitutes. For large-volume production requirements, multiple FCE17 variants provide combined inventory exceeding 7000 units. HARTING alternatives provide additional supply diversity with combined inventory of 1869 units.

Q: Are there any certifications or compliance standards that differentiate the substitute parts?

A: All parts carry UL94 V-0 material flammability rating and MSL 1 (Unlimited) moisture sensitivity level. The FCC17C37PB400 is RoHS non-compliant. The FCE17 series (PB400, PB410, PB440, PB450, PB480, PB490, PB4D0, PB4E0) are RoHS compliant. The HARTING parts (09654226800, 09654227800) are ROHS3 compliant. All parts are classified as EAR99 for export control purposes and share the same HTSUS code (8536.69.4040). For applications requiring specific regulatory compliance (RoHS, ROHS3, REACH), the FCE17 series and HARTING alternatives satisfy these requirements, while the original FCC17C37PB400 does not.
