D09P91C6PL00LF Equivalent & Substitute Parts

Part Overview

The D09P91C6PL00LF is a 9-position D-Sub plug connector manufactured by Amphenol ICC (FCI) in the Delta D series. This through-hole, press-fit connector features male pins with tin-nickel plated steel shell and gold-plated contacts. The part is currently active in production with 984 units in stock.

Substitute parts are necessary when the original D09P91C6PL00LF becomes unavailable, when alternative sourcing is required for supply chain optimization, or when design flexibility permits use of functionally equivalent connectors from different manufacturers or product lines.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the D09P91C6PL00LF is determined by the following critical parameters:

Primary Compatibility Criteria:

• Connector type: Plug with male pins
• Position count: 9 positions
• Shell size and layout: 1 (DE, E)
• Mounting configuration: Through hole
• Termination method: Press-fit
• Voltage rating: 300V minimum
• Operating temperature range: -55°C to 125°C minimum
• Flammability rating: UL94 V-0

Secondary Considerations:

• Current rating: Substitute must meet or exceed 5A per contact requirement
• Shell material and finish: Steel construction acceptable with various plating options
• Contact finish: Gold plating preferred for signal integrity
• RoHS compliance status

The substitute parts listed below satisfy these core electrical and mechanical parameters, enabling direct functional replacement in applications where the D09P91C6PL00LF is specified.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Status, Full Compatibility):

L17TF0910114, L17TF0912112, and L17TF0912101 are all active Amphenol ICC (Commercial Products) connectors that maintain the same 9-position D-Sub plug configuration, through-hole mounting, and press-fit termination as the D09P91C6PL00LF. All three are RoHS compliant and operate across the -55°C to 125°C temperature range with UL94 V-0 flammability rating.

Note: These substitutes carry a 3A current rating per contact, which is lower than the original part's 5A rating. Selection of these parts is appropriate only when circuit current requirements do not exceed 3A per contact.

Alternative Substitute (Higher Current Capacity):

09661646716 (HARTING) provides a 6.5A current rating per contact, exceeding the original specification. However, this part carries an obsolete product status, limiting its suitability for new designs or long-term supply assurance.

Complementary Component (Receptacle):

L17TF0901101 is a 9-position D-Sub receptacle with female sockets, not a direct plug substitute. This part is listed as a related component for mating applications and is not interchangeable with the D09P91C6PL00LF plug connector.

Frequently Asked Questions (FAQ)

Q: Can L17TF0910114, L17TF0912112, or L17TF0912101 be used as direct replacements for D09P91C6PL00LF?

A: These three Amphenol ICC (Commercial Products) connectors are mechanically and electrically compatible for applications where the circuit current requirement does not exceed 3A per contact. The original D09P91C6PL00LF is rated for 5A per contact. If your application requires the full 5A capacity, these substitutes are not suitable.

Q: What is the difference between L17TF0910114, L17TF0912112, and L17TF0912101?

A: All three are 9-position D-Sub plugs with identical core specifications. The differences lie in flange features: L17TF0910114 has Housing/Shell (M3) mounting, L17TF0912101 has Housing/Shell (4-40) mounting, and L17TF0912112 includes Mating Side Female Screwlock (4-40). Selection depends on your specific mounting and mating requirements.

Q: Why is 09661646716 listed as obsolete?

A: HARTING's 09661646716 is marked as obsolete product status, indicating it is no longer in active production. While it remains available in inventory (1095 units), it is not recommended for new designs due to limited long-term supply assurance.

Q: Can I use 09661646716 if I need higher current capacity?

A: The 09661646716 provides 6.5A per contact, exceeding the original 5A requirement. However, its obsolete status makes it unsuitable for applications requiring long-term component availability or supply chain stability.

Q: What is L17TF0901101 and why is it listed?

A: L17TF0901101 is a 9-position D-Sub receptacle (female sockets), not a plug. It is listed as a related component for mating with plug connectors but is not a substitute for the D09P91C6PL00LF plug.

Q: Are all substitute parts RoHS compliant?

A: Yes. L17TF0910114, L17TF0912112, L17TF0912101, and L17TF0901101 are RoHS compliant. The 09661646716 is ROHS3 compliant. All meet current regulatory requirements.

Q: What packaging formats are available?

A: D09P91C6PL00LF is supplied in Tray packaging. L17TF0910114, L17TF0912112, L17TF0912101, and L17TF0901101 are also supplied in Tray packaging. The 09661646716 is supplied in Bulk packaging.
