D09P91C4GL00 D-Sub Connector Equivalent & Substitute Parts

Part Overview

The D09P91C4GL00 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, gold-plated contacts, and a tin-plated steel shell rated for 5A at 300V operation across -55°C to 125°C. The part is currently listed as obsolete, making identification of compatible substitutes essential for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the D09P91C4GL00 is determined by strict equivalence across the following critical parameters:

Connector configuration (9-position D-Sub plug with male pins), shell size (1/DE-E), mounting method (through-hole), termination technology (press-fit), electrical ratings (5A/300V), contact metallurgy (gold finish, phosphor bronze material), shell construction (tin-plated steel), and operating temperature range (-55°C to 125°C).

The substitute part D09P91C4GL00LF maintains identical electrical, mechanical, and material specifications as the original part. The primary distinction is product status and RoHS compliance: the original D09P91C4GL00 is obsolete and RoHS non-compliant, while D09P91C4GL00LF is active and RoHS compliant. Both parts share the same base product number (D09P91) and are packaged identically except for packaging format (tray vs. standard).

Parameter Comparison

Engineering Selection Recommendations

The D09P91C4GL00LF is the direct functional equivalent and recommended substitute for the obsolete D09P91C4GL00. Both connectors are electrically and mechanically interchangeable, with identical pin configurations, electrical ratings, and operating specifications.

Selection between these parts should be based on the following criteria:

For new designs or systems requiring regulatory compliance, D09P91C4GL00LF is the appropriate choice due to its active product status and RoHS compliance certification. This part ensures long-term availability and meets current environmental and regulatory standards.

For legacy system maintenance or repair where the original D09P91C4GL00 specification must be maintained, D09P91C4GL00LF provides full functional compatibility while offering improved compliance posture. The tray packaging format of D09P91C4GL00LF may require adjustment to existing procurement workflows but does not affect connector performance or installation.

Frequently Asked Questions (FAQ)

Q: Are D09P91C4GL00 and D09P91C4GL00LF mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications including shell size (1/DE-E), mounting type (through-hole), pin count (9), and flange configuration (M3). They mount identically on printed circuit boards and mate with the same receptacle connectors.

Q: Are these connectors electrically equivalent?

A: Yes. Both parts have identical electrical ratings (5A, 300V), contact materials (phosphor bronze with gold flash finish), and operating temperature ranges (-55°C to 125°C). They perform identically in circuit applications.

Q: What is the difference between D09P91C4GL00 and D09P91C4GL00LF?

A: The primary differences are product status and regulatory compliance. D09P91C4GL00 is obsolete and RoHS non-compliant. D09P91C4GL00LF is an active product that meets RoHS compliance requirements. Packaging format also differs (standard vs. tray), but connector specifications are identical.

Q: Can D09P91C4GL00LF be used as a direct replacement in existing designs?

A: Yes. D09P91C4GL00LF is a direct substitute with no design modifications required. The connector maintains all electrical, mechanical, and material specifications of the original part.

Q: Why is the original D09P91C4GL00 listed as obsolete?

A: Product obsolescence typically reflects manufacturer discontinuation decisions. The D09P91C4GL00LF represents the current active equivalent in the Delta D series, ensuring ongoing availability and support.

Q: Does packaging format affect connector performance?

A: No. Tray packaging (D09P91C4GL00LF) provides the same connector performance as standard packaging. Packaging format affects only storage, handling, and procurement logistics, not electrical or mechanical function.
