Engineering Selection Recommendations

Primary Selection: FCE17C37SB4DB

The FCE17C37SB4DB remains the primary specification for applications requiring the exact configuration as originally designed. This part maintains active production status, RoHS compliance, and UL94 V-0 flammability certification. Current inventory of 1040 pieces supports immediate availability.

Equivalent Substitutes with Extended Temperature Range:

The D37S13A4GL00LF and D37S13A4GV00LF (both Amphenol ICC FCI, Delta D series) provide direct functional equivalence with extended operating temperature capability (-55°C ~ 125°C versus -40°C ~ 85°C). Both parts maintain identical electrical specifications (5A per contact), UL94 V-0 compliance, and RoHS certification. These substitutes are suitable for applications requiring broader thermal operating envelopes. Inventory availability is 896 and 1108 pieces respectively.

Higher Current Rating Alternative: 09664526613 (HARTING)

The HARTING 09664526613 provides increased current capacity (6.5A versus 5A) while maintaining all critical mechanical and electrical parameters. This part is specified for applications requiring higher current handling capability within the same connector form factor. ROHS3 compliance and UL94 V-0 rating are maintained. Inventory: 848 pieces.

Voltage-Rated Alternative: 5745441-4 (TE Connectivity)

The TE Connectivity AMPLIMITE HDP-20 series 5745441-4 includes explicit voltage rating (125V) and provides 6A current capacity. This part is suitable for applications where voltage specification is a design requirement. Operating temperature range extends to -55°C ~ 105°C. RoHS compliance and UL94 V-0 certification are maintained. Inventory: 950 pieces.

All substitute parts maintain MSL 1 (Unlimited) moisture sensitivity classification and ECCN EAR99 export control status consistent with the main part.

Frequently Asked Questions (FAQ)

Q: Can the D37S13A4GL00LF replace the FCE17C37SB4DB in all applications?

A: The D37S13A4GL00LF is mechanically and electrically compatible for applications operating within the FCE17C37SB4DB temperature range (-40°C ~ 85°C). The substitute part supports extended temperature operation (-55°C ~ 125°C) but does not require this capability for direct replacement. Both parts maintain identical 37-position, 2-row configuration, through-hole right-angle solder termination, and UL94 V-0 compliance. Backset spacing differs slightly (0.409" versus 0.405"), which is within acceptable PCB layout tolerance for standard D-Sub applications.

Q: What is the significance of the backset spacing variation between substitute parts?

A: Backset spacing (0.405" to 0.454") represents the distance from the connector mounting face to the rear of the connector body. Variations within this range are accommodated by standard D-Sub PCB footprint designs. The FCE17C37SB4DB specifies 0.405", while substitutes range from 0.409" to 0.454". PCB layout verification is required to confirm accommodation of the selected substitute's backset spacing, particularly for applications with space constraints behind the mounting plane.

Q: Are all substitute parts RoHS compliant?

A: Yes. The FCE17C37SB4DB and all listed substitute parts maintain RoHS compliance. The main part is RoHS Compliant; HARTING 09664526613 is ROHS3 Compliant; TE Connectivity 5745441-4 is RoHS Compliant; Amphenol ICC FCI D37S13A4GL00LF and D37S13A4GV00LF are RoHS Compliant. ROHS3 represents an updated compliance standard and is fully compatible with RoHS requirements.

Q: What is the difference between D37S13A4GL00LF and D37S13A4GV00LF?

A: Both parts are Amphenol ICC FCI Delta D series connectors with identical electrical and thermal specifications (5A per contact, -55°C ~ 125°C operating range). The primary difference is the flange feature: D37S13A4GL00LF features Housing/Shell (M3) mounting, while D37S13A4GV00LF features Mating Side Female Screwlock (4-40) mounting. Selection depends on the specific mounting interface required by the application. Both parts maintain 300V voltage rating and UL94 V-0 compliance.

Q: Can the HARTING 09664526613 be used in applications requiring the exact current rating of the FCE17C37SB4DB?

A: The HARTING 09664526613 provides 6.5A current capacity, which exceeds the FCE17C37SB4DB specification of 5A. This higher rating does not preclude use in applications designed for 5A operation. The substitute part is suitable for applications operating at or below 5A. Applications requiring the exact 5A specification can use this part without derating concerns, as the higher current capacity provides additional design margin.

Q: What packaging format differences exist among the substitute parts?

A: The FCE17C37SB4DB is supplied in standard packaging (not specified). HARTING 09664526613 is supplied in Tray packaging. TE Connectivity 5745441-4 is supplied in Bulk packaging. Amphenol ICC FCI D37S13A4GL00LF and D37S13A4GV00LF are supplied in Tray packaging. Packaging format does not affect connector functionality or electrical performance; it reflects supplier logistics and handling specifications.

Q: Are all substitute parts suitable for solder termination assembly?

A: Yes. All listed substitute parts specify Solder termination, identical to the FCE17C37SB4DB. All parts are compatible with standard through-hole solder assembly processes. Contact material specifications (Phosphor Bronze or Copper Alloy) and contact finish (Gold or unspecified) are compatible with standard solder reflow and wave soldering processes.

Q: What is the significance of the contact finish thickness specification?

A: The FCE17C37SB4DB specifies contact finish thickness of 15.0µin (0.38µm). Substitute parts D37S13A4GL00LF and D37S13A4GV00LF specify Flash contact finish thickness (not quantified). HARTING 09664526613 does not specify contact finish thickness. Flash finish provides adequate contact durability for standard signal applications. The variation in finish thickness specification does not indicate functional incompatibility; it reflects different manufacturer specification practices for equivalent contact performance.
