Engineering Selection Recommendations

Primary Recommendation: Amphenol ICC FCE17C37 Series

The FCE17C37PC2DB represents the direct active production replacement for the obsolete FCC17C37PC2DB. This connector maintains identical mechanical and electrical specifications while providing RoHS compliance. The FCE17 series is the manufacturer's current standard for 37-position D-Sub plug connectors with right-angle solder termination and shell size 4 configuration.

Selection among FCE17C37 variants (PC20B, PC21B, PC24B, PC25B, PC28B, PC29B, PC2EB) depends on specific application requirements not differentiated by the provided parameters. All variants share identical core specifications and are functionally interchangeable within the same design.

Secondary Recommendation: HARTING 09654226800 or 09654227800

HARTING alternatives provide functional equivalence with the following considerations:

Current rating of 6.5A exceeds the 5A requirement, providing design margin
Extended operating temperature range (-55°C to 125°C) accommodates broader environmental conditions
Backset spacing of 0.409" differs from the 0.590" standard, requiring PCB layout verification
Copper alloy contact material differs from phosphor bronze, affecting contact resistance characteristics
ROHS3 compliance status exceeds RoHS requirements

HARTING connectors are suitable for applications where the reduced backset spacing is compatible with existing PCB designs and where extended temperature performance is beneficial.

Compliance Considerations:

New designs should prioritize RoHS-compliant alternatives. The FCE17C37 series provides direct compliance with current regulatory requirements while maintaining full mechanical and electrical compatibility with the original FCC17C37PC2DB specification.

Frequently Asked Questions (FAQ)

Q: Can the FCE17C37PC2DB directly replace the FCC17C37PC2DB in existing designs?

A: Yes. The FCE17C37PC2DB maintains identical mechanical and electrical specifications including connector position count (37), shell size (4/DC,C), mounting type (through-hole right angle), termination method (solder), current rating (5A), voltage rating (200V), operating temperature range (-40°C to 85°C), and backset spacing (0.590"). The primary difference is RoHS compliance status and improved dielectric material composition.

Q: What is the significance of the different FCE17C37 part number suffixes (PC20B, PC21B, PC24B, PC25B, PC28B, PC29B, PC2EB)?

A: The suffix designations indicate variations in contact finish specifications or other minor construction details not differentiated in the provided parameters. All variants maintain identical core electrical and mechanical specifications and are functionally equivalent for standard applications.

Q: Are HARTING 09654226800 and 09654227800 connectors fully compatible with FCC17C37PC2DB applications?

A: These HARTING connectors provide functional equivalence for 37-position D-Sub plug applications with right-angle solder termination. However, the backset spacing differs (0.409" versus 0.590"), requiring verification that existing PCB layouts accommodate this dimensional change. The higher current rating (6.5A) and extended temperature range (-55°C to 125°C) represent performance enhancements suitable for demanding applications.

Q: What is backset spacing and why does it matter for connector substitution?

A: Backset spacing is the distance from the rear of the connector shell to the solder contact points. The FCC17C37PC2DB specifies 0.590" (14.99mm), while HARTING alternatives specify 0.409" (10.40mm). This dimension directly affects PCB layout and mounting depth. Substitution with different backset spacing requires PCB redesign verification.

Q: Why is the FCC17C37PC2DB listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The FCE17C37 series represents the current production equivalent, offering improved specifications including RoHS compliance and enhanced dielectric materials while maintaining full backward compatibility.

Q: Does RoHS compliance affect electrical performance?

A: RoHS compliance addresses material composition restrictions (lead, cadmium, mercury, etc.) rather than electrical performance. The FCE17C37 series maintains identical electrical ratings and performance characteristics while meeting RoHS requirements through material substitution in non-critical components.

Q: Can I mix FCC17C37PC2DB and FCE17C37PC2DB connectors in the same assembly?

A: Yes. Both connectors are mechanically and electrically compatible. However, mixing obsolete and current production parts in the same assembly is not recommended for long-term supply chain management. Standardizing on the active FCE17C37 series ensures consistent availability and compliance status across production runs.

Q: What contact material differences exist between substitute options?

A: The FCC17C37PC2DB and all FCE17C37 variants use phosphor bronze contacts, while HARTING alternatives use copper alloy. Phosphor bronze provides superior corrosion resistance and contact reliability in demanding applications. Copper alloy contacts are suitable for standard industrial applications with adequate environmental protection.
