D09P91C4GV00 D-Sub Connector Equivalent & Substitute Parts

Part Overview

The D09P91C4GV00 is a 9-position D-Sub plug connector with male pins, manufactured by Amphenol ICC (FCI) in the Delta D series. This through-hole mounted connector features press-fit termination, a tin-plated steel shell, and gold-flashed contacts rated for 5A at 300V. The part is currently obsolete, making identification of compatible substitutes essential for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the D09P91C4GV00 is determined by strict equivalence across the following critical parameters:

• Connector type, gender, and pin count (9-position D-Sub plug with male pins)
• Shell size and layout (Size 1, DE/E configuration)
• Mounting method (through-hole)
• Termination technology (press-fit)
• Electrical ratings (5A current, 300V voltage)
• Operating temperature range (-55°C to 125°C)
• Contact and dielectric materials (phosphor bronze contacts, PBT dielectric)
• Flange configuration (mating side screwlock)

The D09P91C4GV00LF meets all these criteria and is classified as a direct substitute. Differences in shell finish (tin-nickel plated versus tin-plated) and compliance status do not affect functional interchangeability in the specified electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

The D09P91C4GV00LF is the direct functional equivalent of the obsolete D09P91C4GV00. Both connectors share identical electrical and mechanical specifications across all critical parameters: 9-position configuration, 5A/300V ratings, press-fit termination, and operating temperature range.

The primary distinction is product status and regulatory compliance. The D09P91C4GV00LF is an active product with RoHS compliance and REACH unaffected status, whereas the original part is obsolete and RoHS non-compliant. The shell finish difference (tin-nickel plated versus tin-plated) provides enhanced corrosion resistance in the substitute part without affecting electrical performance or mechanical fit.

For new designs or component replacement in existing systems, the D09P91C4GV00LF is the appropriate selection. Both parts are manufactured by the same supplier within the same Delta D series, ensuring design continuity and interchangeability.

Frequently Asked Questions (FAQ)

Q: Can the D09P91C4GV00LF be used as a direct replacement for the D09P91C4GV00?

A: Yes. Both connectors are electrically and mechanically equivalent across all specified parameters. The D09P91C4GV00LF is the active production equivalent of the obsolete D09P91C4GV00.

Q: What is the difference between the tin-plated and tin-nickel plated shell finishes?

A: Tin-nickel plating provides improved corrosion resistance compared to tin plating alone. Both finishes meet the same electrical and mechanical requirements for this connector application.

Q: Are there any packaging differences between these parts?

A: The D09P91C4GV00 is supplied in standard packaging, while the D09P91C4GV00LF is supplied in trays. This is a logistical difference only and does not affect connector performance or compatibility.

Q: Does the RoHS compliance difference affect interchangeability?

A: No. RoHS compliance is a regulatory and supply chain consideration, not a functional parameter. Both connectors meet identical electrical and mechanical specifications.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by equivalence in connector type and gender, pin count, shell size, mounting method, termination technology, electrical ratings, operating temperature range, contact and dielectric materials, and flange configuration.
