Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for D37P91C6PL00 is determined by strict equivalence across the following critical parameters:

• Connector type, gender, and pin count (37-position D-Sub plug with male pins)
• Shell size and layout (Size 4, DC/C configuration)
• Mounting method (through-hole)
• Termination technology (press-fit)
• Electrical ratings (5A per contact, 300V)
• Operating temperature range (-55°C to 125°C)
• Contact material and finish specifications (phosphor bronze with gold plating)
• Dielectric material (PBT)
• Flammability compliance (UL94 V-0)

The substitute part D37P91C6PL00LF meets all these criteria. Variations in shell plating finish (tin-plated versus tin-nickel plated) and product status (obsolete versus active) do not affect functional compatibility when electrical and mechanical parameters remain equivalent.

Parameter Comparison

Engineering Selection Recommendations

D37P91C6PL00LF is the direct substitute for D37P91C6PL00. Both connectors are functionally equivalent across all electrical and mechanical parameters critical to connector performance and interchangeability.

The primary distinction is product lifecycle status: D37P91C6PL00 is obsolete, while D37P91C6PL00LF is active production. D37P91C6PL00LF also carries RoHS compliance certification, whereas the original part does not. For new designs or ongoing procurement, D37P91C6PL00LF is the appropriate selection. The tin-nickel plating on D37P91C6PL00LF provides equivalent corrosion resistance to the tin plating of the original part within the specified operating environment.

Frequently Asked Questions (FAQ)

Q: Can D37P91C6PL00LF be used as a direct replacement for D37P91C6PL00?

A: Yes. Both connectors share identical electrical ratings (5A per contact, 300V), mechanical configuration (37-position D-Sub plug, through-hole mount, press-fit termination), contact materials (phosphor bronze with gold plating), and operating temperature range (-55°C to 125°C). The shell plating difference (tin versus tin-nickel) does not affect functional compatibility.

Q: What is the significance of the RoHS compliance difference?

A: D37P91C6PL00LF is RoHS compliant, while D37P91C6PL00 is not. For applications subject to RoHS regulations or customer requirements, D37P91C6PL00LF is the required selection. Both parts are otherwise electrically and mechanically equivalent.

Q: Are there packaging differences between these parts?

A: D37P91C6PL00LF is supplied in tray packaging. Packaging does not affect connector performance or interchangeability in the application.

Q: Why is D37P91C6PL00 listed as obsolete?

A: D37P91C6PL00 has been discontinued by the manufacturer. D37P91C6PL00LF represents the active production equivalent and is the recommended source for current procurement.

Q: Can these connectors be intermixed in the same assembly?

A: Yes. Both connectors are mechanically and electrically interchangeable. They can be used together in the same system without compatibility issues.
