Engineering Selection Recommendations
Amphenol ICC FCE17 Series (FCE17C37PA21B, FCE17C37PA20B, FCE17C37PA24B, FCE17C37PA25B, FCE17C37PA28B, FCE17C37PA29B, FCE17C37PA2DB, FCE17C37PA2EB):
These parts represent the primary substitution path for the obsolete FCC17C37PA21B. All FCE17 variants maintain identical mechanical form-fit-function compatibility with the original part while offering active product status and RoHS compliance. The FCE17 series provides superior supply chain availability and long-term production support. Selection among FCE17 variants depends on specific application requirements not differentiated in the provided parameter set. These parts are recommended for new designs and production transitions from the FCC17 platform.
HARTING 09654226800 and 09654227800:
These cross-manufacturer alternatives provide functional D-Sub 37-position right-angle solder plug connectivity with enhanced current rating (6.5A versus 5A) and extended operating temperature range (-55°C to 125°C versus -40°C to 85°C). However, these parts feature differing backset spacing (0.409" versus 0.318"), copper alloy contact material (versus phosphor bronze), and unspecified contact finish specifications. These parts are suitable for applications where mechanical envelope tolerance and contact material composition variations are acceptable. HARTING parts offer ROHS3 compliance and extended environmental performance.
Compliance Considerations:
The FCC17C37PA21B is RoHS non-compliant. All Amphenol ICC FCE17 alternatives and HARTING substitutes are RoHS compliant, meeting current regulatory requirements for new equipment designs and production in regulated markets.
Frequently Asked Questions (FAQ)
Q: Can FCE17C37PA21B directly replace FCC17C37PA21B in existing designs?
A: Yes. The FCE17C37PA21B maintains identical mechanical dimensions, electrical ratings, and contact specifications as the FCC17C37PA21B. The primary differences are product status (active versus obsolete) and RoHS compliance. No design modifications are required for direct substitution.
Q: What is the difference between the multiple FCE17 variants (PA20B, PA24B, PA25B, PA28B, PA29B, PA2DB, PA2EB)?
A: All listed FCE17 variants share identical electrical and mechanical parameters as specified in the provided data. Differences between variants are not documented in the available parameter set. Consult Amphenol ICC technical documentation for variant-specific distinctions.
Q: Are HARTING 09654226800 and 09654227800 suitable for direct replacement?
A: These HARTING parts provide functional D-Sub 37-position right-angle solder plug connectivity but differ in backset spacing (0.409" versus 0.318"), contact material (copper alloy versus phosphor bronze), and contact finish specifications. Direct replacement is possible only if the application tolerates these mechanical and material variations. PCB layout modifications may be required due to backset spacing differences.
Q: What is backset spacing and why does it matter?
A: Backset spacing is the distance from the rear of the connector shell to the solder pin termination points. The FCC17C37PA21B and all Amphenol ICC FCE17 variants specify 0.318" (8.08mm) backset spacing, while HARTING alternatives specify 0.409" (10.40mm). This difference affects PCB layout and mounting hole positioning. Substitution with different backset spacing requires PCB redesign.
Q: Why is the FCC17C37PA21B obsolete?
A: The FCC17C37PA21B is classified as obsolete due to product line evolution. Amphenol ICC has transitioned the design to the active FCE17 series, which provides improved compliance, manufacturing efficiency, and supply chain continuity. The FCE17 series represents the current production standard for this connector category.
Q: Are all substitute parts RoHS compliant?
A: Yes. All listed substitute parts (FCE17 series and HARTING alternatives) are RoHS compliant. The original FCC17C37PA21B is RoHS non-compliant. Substitution with any listed alternative satisfies RoHS regulatory requirements.
Q: What is the current rating difference between FCC17C37PA21B and HARTING alternatives?
A: The FCC17C37PA21B and all Amphenol ICC FCE17 variants are rated for 5A continuous current. HARTING 09654226800 and 09654227800 are rated for 6.5A. The higher HARTING rating provides additional current capacity margin but does not affect compatibility for applications within the 5A specification.
Q: Can I use HARTING parts in applications requiring -40°C to 85°C operation?
A: Yes. HARTING 09654226800 and 09654227800 specify -55°C to 125°C operating temperature range, which encompasses the -40°C to 85°C requirement of the FCC17C37PA21B. HARTING parts provide extended environmental performance for this parameter.
Q: What inventory status should I consider for procurement?
A: Current inventory levels are: FCC17C37PA21B (1027 pcs), FCE17C37PA21B (1142 pcs), FCE17C37PA20B (967 pcs), FCE17C37PA24B (969 pcs), FCE17C37PA25B (881 pcs), FCE17C37PA28B (951 pcs), FCE17C37PA29B (875 pcs), FCE17C37PA2DB (1005 pcs), FCE17C37PA2EB (890 pcs), HARTING 09654226800 (1047 pcs), and HARTING 09654227800 (822 pcs). All parts show adequate stock availability for production requirements.
