Substitute Part Grouping Explanation

Substitution eligibility for the D09S91C4PL00 is determined by strict equivalence across the following critical parameters:

• Connector Style & Type: Must be D-Sub receptacle with female sockets
• Position & Row Configuration: Must maintain 9 positions in 2-row layout
• Shell Size & Layout: Must conform to Size 1 (DE, E) specification
• Mounting & Termination: Must support through-hole mounting with press-fit termination
• Electrical Ratings: Must maintain 5A current capacity and 300V voltage rating
• Temperature Range: Must support -55°C ~ 125°C operating window
• Material & Finish Specifications: Shell material, contact material, and finish specifications must be compatible with the original design requirements
• Flange Configuration: Must include M3 housing/shell flange feature

The substitute part D09S91C4PL00LF meets all these criteria while offering improved compliance status and active product availability.

Parameter Comparison

Engineering Selection Recommendations

The D09S91C4PL00LF is the direct active equivalent for the obsolete D09S91C4PL00. Both parts share identical electrical and mechanical specifications, including connector configuration, pin count, mounting method, and operating parameters. The substitute part maintains full functional compatibility while offering the following advantages:

Product Status: The D09S91C4PL00LF carries active product status, ensuring continued availability and supply chain reliability compared to the obsolete original part.

Compliance: The substitute part is RoHS compliant, whereas the original part is RoHS non-compliant. This distinction is significant for applications subject to RoHS regulations and for long-term design compliance requirements.

Shell Finish: The substitute features tin-nickel plating on the steel shell, compared to tin plating on the original. Both finishes provide equivalent corrosion resistance and electrical performance within the specified operating parameters.

Packaging: The substitute is supplied in tray packaging, which may differ from the original packaging configuration but does not affect functional performance or installation characteristics.

For new designs and procurement of replacement units, the D09S91C4PL00LF is the appropriate selection. Existing designs using the D09S91C4PL00 can transition to the substitute part without modification to PCB layouts, mating connectors, or electrical circuits.

Frequently Asked Questions (FAQ)

Q: Can D09S91C4PL00LF be used as a direct replacement for D09S91C4PL00 in existing assemblies?

A: Yes. Both parts are functionally equivalent across all critical parameters including connector type, pin configuration, electrical ratings, and operating temperature range. The substitute part maintains identical mechanical fit and electrical performance.

Q: What is the difference between the shell finishes (tin plated vs. tin-nickel plated)?

A: Both finishes provide corrosion protection and electrical conductivity suitable for the specified operating environment. Tin-nickel plating offers enhanced durability in certain corrosive environments. For standard applications within the specified operating parameters, both finishes are functionally equivalent.

Q: Why is RoHS compliance status different between the two parts?

A: The D09S91C4PL00LF is manufactured to meet RoHS directives, while the D09S91C4PL00 predates or was not manufactured to these standards. For applications subject to RoHS regulations or for designs requiring regulatory compliance, the substitute part is the appropriate selection.

Q: Are there any PCB layout or design modifications required when switching from D09S91C4PL00 to D09S91C4PL00LF?

A: No. Both parts share identical mounting specifications, pin layouts, and mechanical dimensions. No PCB modifications are required for substitution.

Q: What is the packaging difference, and does it affect installation?

A: The substitute part is supplied in tray packaging. Packaging format does not affect connector performance, installation, or electrical characteristics. Tray packaging is standard for high-volume production environments.

Q: Are the electrical ratings identical between both parts?

A: Yes. Both parts maintain 5A current capacity per contact and 300V voltage rating. Operating temperature range, dielectric material, and contact specifications are identical.

Q: Can the D09S91C4PL00LF be used in applications originally designed for the D09S91C4PL00?

A: Yes. The substitute part is fully compatible with existing mating connectors, PCB layouts, and circuit designs. No design changes are necessary.
