D09P91C4PV00LF D-Sub Plug 9 Position Equivalent & Substitute Parts

Part Overview

The D09P91C4PV00LF is a 9 Position D-Sub Plug connector manufactured by Amphenol ICC (FCI) in the Delta D series. This through-hole mounted connector features male pins with press-fit termination and is rated for 5A per contact at 300V. The part is currently active in production with 618 units in stock.

Equivalent and substitute parts are necessary when the primary part becomes unavailable, when alternative sourcing is required for supply chain optimization, or when design flexibility permits selection from compatible connector variants that meet the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

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

• Connector style (D-Sub)
• Connector type (Plug with male pins)
• Number of positions (9)
• Number of rows (2)
• Shell size and layout (1 / DE, E)
• Mounting type (Through Hole)
• Termination method (Press-Fit)
• Operating temperature range (-55°C ~ 125°C)
• Material flammability rating (UL94 V-0)
• Compliance status (RoHS)

The substitute parts listed below meet these core mechanical and electrical compatibility criteria. Variations in current rating, contact finish, shell material finish, and flange feature design are permitted within the scope of D-Sub connector standardization, provided the connector maintains functional interchangeability in the intended application.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Status):

L17TF0912112 and L17TF0910114 are the preferred substitutes. Both are manufactured by Amphenol ICC (Commercial Products), maintain active product status, and share identical mechanical compatibility with the D09P91C4PV00LF. L17TF0912112 matches the flange feature configuration (Mating Side, Female Screwlock 4-40) of the main part. Both parts carry RoHS Compliant certification and meet UL94 V-0 flammability requirements.

Current rating on these substitutes is 3A per contact, compared to 5A on the main part. This reduction in current capacity must be evaluated against application requirements.

Secondary Substitutes (Active Status):

L17TF0912101 and L17TF0901101 are active alternatives. L17TF0912101 is a plug connector with Housing/Shell flange (4-40), while L17TF0901101 is a receptacle connector. Both maintain full mechanical and thermal compatibility. L17TF0901101 is a receptacle type and is not a direct plug substitute; it is listed for reference in connector pair applications.

Obsolete Alternative:

09661646716 (HARTING) is obsolete and should not be selected for new designs or long-term supply planning. While it meets core mechanical specifications and exceeds current rating at 6.5A, its discontinued status makes it unsuitable for production use.

Frequently Asked Questions (FAQ)

Q: Can L17TF0912112 directly replace D09P91C4PV00LF in my application?

A: L17TF0912112 is mechanically and electrically compatible for applications requiring 3A or less per contact. The connector maintains the same 9-position, 2-row DE/E shell size, through-hole mounting, and press-fit termination. If your application requires the full 5A rating of the original part, this substitute is not suitable.

Q: What is the difference between L17TF0912112 and L17TF0910114?

A: Both are 9-position D-Sub plugs from Amphenol ICC (Commercial Products) with identical current and voltage ratings. The primary difference is the flange feature: L17TF0912112 has Mating Side Female Screwlock (4-40), matching the original part's flange design, while L17TF0910114 has Housing/Shell (M3) flange. Select based on your mechanical mounting requirements.

Q: Why is L17TF0901101 listed as a substitute if it is a receptacle?

A: L17TF0901101 is included for reference in applications requiring both plug and receptacle connectors in a mated pair. It is not a direct substitute for the plug connector D09P91C4PV00LF.

Q: Is 09661646716 suitable for new designs?

A: No. Although 09661646716 meets mechanical specifications and offers higher current rating (6.5A), it is obsolete. New designs should use active alternatives such as L17TF0912112 or L17TF0910114 to ensure long-term supply availability and manufacturing support.

Q: Are all substitutes RoHS compliant?

A: Yes. All listed substitutes carry RoHS Compliant or ROHS3 Compliant certification, meeting regulatory requirements for hazardous substance restrictions.

Q: What packaging is available for substitute parts?

A: L17TF0912112, L17TF0910114, L17TF0912101, and L17TF0901101 are supplied in Tray packaging. 09661646716 is supplied in Bulk packaging. Verify packaging requirements with your procurement process.
