D-Sub Connector D09P91C6PX00LF Equivalent & Substitute Parts

Part Overview

The D09P91C6PX00LF is a 9-position D-Sub plug connector with male pins, manufactured by Amphenol ICC under the Delta D series. This through-hole mounted connector features press-fit termination and is designed for signal applications requiring robust mechanical and electrical performance. The part is currently active in production with 1012 units in stock. Substitute parts are identified when equivalent electrical and mechanical specifications are required due to availability constraints, design revisions, or procurement optimization.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for D-Sub connectors is determined by the following critical parameters:

• Connector Layout & Shell Size: Must match 1 (DE, E) configuration to ensure mechanical compatibility with mating connectors
• Number of Positions: Must be 9 positions to maintain pin count equivalence
• Mounting Type: Through-hole mounting is required for PCB integration compatibility
• Termination Method: Press-fit termination ensures consistent assembly and electrical performance
• Voltage & Current Ratings: Minimum 300V voltage rating and adequate current capacity for the application
• Operating Temperature Range: Must support -55°C ~ 125°C to maintain performance across specified conditions
• RoHS Compliance: Required for regulatory and procurement standards

The identified substitute part L17TF0901101 shares the same shell size, position count, mounting type, termination method, voltage rating, temperature range, and RoHS compliance status. However, it is a receptacle (female sockets) configuration rather than a plug (male pins), making it suitable only for mating pair applications where a receptacle is required.

Parameter Comparison

Engineering Selection Recommendations

Both parts are active products with RoHS compliance and equivalent regulatory certifications. Selection between D09P91C6PX00LF and L17TF0901101 is determined by connector gender requirement:

• D09P91C6PX00LF is specified when a plug (male pins) configuration is required for the application
• L17TF0901101 is specified when a receptacle (female sockets) configuration is required, such as for mating with a plug connector

The current rating difference (5A vs. 3A per contact) must be evaluated against application requirements. Both parts support the same voltage rating and operating temperature range, ensuring thermal and electrical performance equivalence within their respective current specifications.

Frequently Asked Questions (FAQ)

Q: Can L17TF0901101 directly replace D09P91C6PX00LF in an assembly?

A: No. L17TF0901101 is a receptacle (female sockets) while D09P91C6PX00LF is a plug (male pins). They are complementary connector types designed to mate with each other, not to replace each other in the same position. Substitution is valid only when the application design calls for a receptacle configuration.

Q: Are the shell sizes and pin layouts identical?

A: Yes. Both parts use shell size 1 (DE, E) with 9-position configuration, ensuring mechanical compatibility with standard D-Sub mating pairs and PCB layouts designed for this form factor.

Q: What is the significance of the current rating difference?

A: D09P91C6PX00LF supports 5A per contact while L17TF0901101 supports 3A per contact. Applications requiring current levels between 3A and 5A per contact must use D09P91C6PX00LF. Applications with current requirements at or below 3A per contact can use either part based on connector gender requirements.

Q: Are both parts suitable for the same temperature range?

A: Yes. Both parts operate across -55°C ~ 125°C, providing equivalent thermal performance for applications requiring extended temperature operation.

Q: Do both parts meet RoHS compliance requirements?

A: Yes. Both D09P91C6PX00LF and L17TF0901101 are RoHS compliant, meeting regulatory requirements for lead-free and restricted substance standards.

Q: What is the difference in shell material finish?

A: D09P91C6PX00LF uses steel with tin-nickel plating, while L17TF0901101 uses steel with tin plating. Both finishes provide corrosion resistance and are suitable for standard environmental conditions. The tin-nickel finish of D09P91C6PX00LF offers enhanced durability in more demanding environments.
