Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for D-Sub 9 position receptacle connectors is determined by strict alignment of the following critical parameters:

• Connector Configuration: Receptacle type with female sockets, 9 positions, 2 rows, shell size 1 (DE, E layout)
• Mounting and Termination: Through-hole mounting with press-fit termination
• Electrical Performance: Voltage rating of 300V, operating temperature range of -55°C to 125°C, gold contact finish at 30.0µin thickness
• Compliance: RoHS compliant status, UL94 V-0 flammability rating, MSL 1 rating
• Material Specifications: Phosphor bronze contact material, dielectric material composition

The substitute part L17TF0902100 meets these core substitution criteria while operating within the allowed parameter tolerances for this connector category.

Parameter Comparison

Engineering Selection Recommendations

Both D09S91C6GL00LF and L17TF0902100 are active production parts with RoHS compliance and UL94 V-0 flammability certification. The primary distinction between these connectors is the current rating specification: the main part supports 5A per contact, while the substitute supports 3A per contact. Selection between these parts must be based on the actual current requirements of the application circuit. Both parts maintain identical voltage ratings, operating temperature ranges, contact finish specifications, and MSL ratings. The shell finish difference (tin-nickel versus tin plating) does not affect functional compatibility for standard signal applications. Both parts are manufactured by Amphenol ICC and are available in production quantities.

Frequently Asked Questions (FAQ)

Q: Can L17TF0902100 be used as a direct replacement for D09S91C6GL00LF?

A: L17TF0902100 is functionally compatible for applications where the circuit current per contact does not exceed 3A. If the application requires the full 5A per contact capability of the main part, L17TF0902100 is not suitable.

Q: What is the difference between the shell finishes?

A: The main part features tin-nickel plating while the substitute features tin plating. Both finishes provide corrosion resistance and are suitable for standard signal applications. The choice between them depends on specific environmental and reliability requirements of the end application.

Q: Are both parts RoHS compliant?

A: Yes, both D09S91C6GL00LF and L17TF0902100 are RoHS compliant and carry UL94 V-0 flammability ratings.

Q: Do these connectors have identical pin configurations?

A: Yes, both connectors are 9 position D-Sub receptacles with shell size 1 (DE, E layout) and identical pin arrangements. They are mechanically and electrically compatible in terms of mating interface.

Q: What is the MSL rating and why does it matter?

A: Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity limitations during storage or handling. Standard storage conditions apply without special desiccant requirements.

Q: Can these connectors be used in high-temperature applications?

A: Both connectors are rated for operating temperatures from -55°C to 125°C, making them suitable for industrial and automotive applications within this temperature range.
