Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the D09S91C4GL00 is determined by strict equivalence across the following critical parameters:

• Connector style and type (D-Sub receptacle, female sockets)
• Position count and row configuration (9 positions, 2 rows)
• 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 ~ 125°C)
• Material specifications (steel shell with tin plating, phosphor bronze contacts with gold flash finish, PBT dielectric)
• Mechanical features (M3 housing/shell flange, board lock)
• Flammability compliance (UL94 V-0)

The substitute part D09S91C4GL00LF meets all these criteria and is therefore a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The D09S91C4GL00LF is the direct substitute for the obsolete D09S91C4GL00. Both parts share identical electrical, mechanical, and material specifications across all functional parameters.

The primary distinction between the two parts is product status and regulatory compliance. The D09S91C4GL00LF is active in production and RoHS compliant, whereas the D09S91C4GL00 is obsolete and RoHS non-compliant. For new designs or ongoing production requiring RoHS compliance, the D09S91C4GL00LF is the appropriate selection. For legacy system support where RoHS non-compliance is acceptable, either part may be used provided functional equivalence is confirmed.

Frequently Asked Questions (FAQ)

Q: Can D09S91C4GL00LF be used as a direct replacement for D09S91C4GL00?

A: Yes. The D09S91C4GL00LF is functionally equivalent to the D09S91C4GL00 across all electrical, mechanical, and material parameters. Both connectors are 9 position D-Sub receptacles with identical ratings, termination methods, and physical specifications.

Q: What is the difference between D09S91C4GL00 and D09S91C4GL00LF?

A: The primary differences are product status and regulatory compliance. The D09S91C4GL00 is obsolete and RoHS non-compliant. The D09S91C4GL00LF is active in production and RoHS compliant. All functional specifications are identical.

Q: Does the packaging difference affect compatibility?

A: No. Packaging format (tray for D09S91C4GL00LF versus unspecified for D09S91C4GL00) does not affect connector functionality or performance. Packaging is a logistics consideration only.

Q: Are there any compatibility concerns when substituting these parts?

A: No compatibility concerns exist. The connectors are mechanically and electrically interchangeable. Both feature identical shell sizes, pin configurations, mounting methods, and electrical ratings.

Q: Which part should be selected for new designs?

A: D09S91C4GL00LF should be selected for new designs. It is active in production, RoHS compliant, and functionally equivalent to the obsolete D09S91C4GL00.
