Engineering Selection Recommendations

Primary Substitutes (Amphenol ICC FCE17 Series)

The FCE17C37PB4EB, FCE17C37PB40B, FCE17C37PB41B, FCE17C37PB44B, FCE17C37PB45B, FCE17C37PB48B, FCE17C37PB49B, and FCE17C37PB4DB represent the most direct substitutes for the FCC17C37PB4EB. All variants are manufactured by Amphenol ICC (Commercial Products) and maintain identical electrical and mechanical specifications with the following advantages:

All FCE17 variants are classified as Active product status, ensuring ongoing availability and supply chain support
All FCE17 variants are RoHS Compliant, meeting current environmental and regulatory requirements
Electrical parameters (37 positions, 5A current rating, -40°C ~ 85°C operating range) are identical to the original
Mechanical compatibility is maintained through identical shell size (4, DC, C), mounting type (through-hole right angle), and backset spacing (0.405" / 10.29mm)
All variants feature UL94 V-0 flammability rating and MSL 1 (Unlimited) moisture sensitivity level

The FCE17 series variants differ only in internal contact configuration or plating specifications not affecting standard D-Sub 37-position plug functionality. Selection among FCE17 variants should be based on specific application requirements and internal contact specifications.

Secondary Substitutes (HARTING 09654226800 and 09654227800)

The HARTING 09654226800 and 09654227800 connectors provide alternative sourcing from a different manufacturer while maintaining core D-Sub 37-position plug compatibility. These parts are classified as Active and ROHS3 Compliant. Considerations for HARTING substitutes include:

Current rating of 6.5A exceeds the original 5A specification, providing additional capacity margin
Operating temperature range of -55°C ~ 125°C exceeds the original -40°C ~ 85°C specification, supporting extended environmental applications
Backset spacing of 0.409" (10.40mm) represents a 0.04mm variation from the original 0.405" (10.29mm), within typical manufacturing tolerances for D-Sub connectors
Flange feature configuration differs (Housing/Shell Unthreaded versus Board Side 4-40), requiring mechanical design verification for mounting compatibility
Contact material is Copper Alloy rather than Phosphor Bronze, maintaining electrical performance within D-Sub specifications

HARTING substitutes are suitable for applications where extended temperature range and higher current capacity provide design benefits and where mechanical mounting configuration is compatible with the target application.

Frequently Asked Questions (FAQ)

Q: Can the FCE17C37PB4EB series directly replace the FCC17C37PB4EB in existing designs?

A: Yes. The FCE17C37PB4EB and related FCE17 variants maintain identical electrical and mechanical specifications for the 37-position D-Sub plug connector. Footprint, pin configuration, current rating, voltage rating, and operating temperature range are equivalent. The primary difference is product status (Active versus Obsolete) and RoHS compliance (Compliant versus non-compliant). No design modifications are required for direct substitution.

Q: What is the significance of the different FCE17 part number suffixes (PB40B, PB41B, PB44B, PB45B, PB48B, PB49B, PB4DB)?

A: The suffix variations indicate differences in internal contact configuration, plating specifications, or manufacturing process parameters that do not affect the external D-Sub 37-position plug interface. All variants maintain identical pin count, shell size, mounting type, and electrical ratings. Selection among variants should be based on specific internal contact requirements for the target application. Consult detailed product specifications for internal contact configuration details.

Q: Are HARTING 09654226800 and 09654227800 connectors mechanically compatible with the original FCC17C37PB4EB?

A: HARTING substitutes maintain D-Sub 37-position plug compatibility and identical pin configuration. However, the flange feature differs: HARTING parts feature Housing/Shell (Unthreaded) configuration versus the original Board Side (4-40) configuration. This difference affects mechanical mounting. Backset spacing variation of 0.04mm (0.409" versus 0.405") is within standard D-Sub manufacturing tolerances. Mechanical design verification is required to confirm mounting compatibility with the target PCB or housing design.

Q: What is the impact of RoHS compliance differences between the original and substitute parts?

A: The FCC17C37PB4EB is RoHS non-compliant, while all FCE17 variants and HARTING substitutes are RoHS Compliant or ROHS3 Compliant. RoHS compliance indicates the absence of restricted substances (lead, cadmium, mercury, hexavalent chromium, polybrominated biphenyls, and polybrominated diphenyl ethers) in the connector construction. For new designs or applications subject to RoHS regulations, the compliant substitutes are required. For legacy equipment maintenance, either compliant or non-compliant parts are functionally equivalent.

Q: Can HARTING connectors be used in applications requiring the original 5A current rating?

A: Yes. HARTING 09654226800 and 09654227800 connectors are rated for 6.5A, which exceeds the original 5A specification. The higher current rating provides additional capacity margin and is fully compatible with applications designed for 5A operation. No design modifications are required.

Q: What is the difference between Phosphor Bronze and Copper Alloy contact materials?

A: Both materials are standard for D-Sub connector contacts and provide equivalent electrical performance within D-Sub specifications. Phosphor Bronze (used in Amphenol ICC parts) and Copper Alloy (used in HARTING parts) both offer reliable conductivity, corrosion resistance, and mechanical durability. Material selection does not affect electrical compatibility or performance in standard D-Sub applications.

Q: Are there any temperature range limitations when substituting with HARTING connectors?

A: HARTING connectors feature an extended operating temperature range of -55°C ~ 125°C compared to the original -40°C ~ 85°C. This extended range is fully backward compatible with the original specification. Applications operating within the original -40°C ~ 85°C range will function identically with HARTING substitutes. Applications requiring extended temperature operation benefit from the HARTING specification.

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

A: Current inventory levels are as follows: FCC17C37PB4EB (680 pcs), FCE17C37PB4EB (715 pcs), FCE17C37PB40B (774 pcs), FCE17C37PB41B (1036 pcs), FCE17C37PB44B (1123 pcs), FCE17C37PB45B (1015 pcs), FCE17C37PB48B (864 pcs), FCE17C37PB49B (1138 pcs), FCE17C37PB4DB (792 pcs), 09654226800 (1047 pcs), and 09654227800 (822 pcs). Inventory levels are subject to change. Consult current stock status for procurement planning.

Q: Is the 0.04mm backset spacing difference between Amphenol ICC and HARTING parts significant?

A: The 0.04mm difference (0.405" versus 0.409") is within standard D-Sub connector manufacturing tolerances and does not affect electrical or functional compatibility. However, mechanical mounting design should account for this tolerance variation. For applications with tight mechanical constraints, verify that the backset spacing variation does not impact PCB layout or housing fit.
