L777DFEH09P D-Sub Connector - Equivalent & Substitute Parts

Part Overview

The L777DFEH09P is a 9 Position D-Sub Plug connector with male pins, manufactured by Amphenol ICC (Commercial Products). This panel mount connector features solder cup termination, steel tin-plated shell, and gold-plated contacts rated for 7.5A at 300V. The product is active and in stock with 932 units available. Alternative connector models are necessary when application requirements deviate from panel mount configurations, when different thermal operating ranges are required, or when alternative manufacturers provide equivalent electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the L777DFEH09P is determined by equivalence in the following critical electrical and mechanical parameters:

• Connector Type & Positions: All substitutes must be D-Sub Plug connectors with 9 positions and 2-row configuration maintaining DE/E shell size compatibility
• Termination Method: All listed substitutes feature solder cup termination for direct PCB or cable assembly compatibility
• Contact Type & Material: Signal contacts with machined or stamped forms in brass or copper alloy materials provide equivalent current-carrying capacity
• Flammability Rating: All substitutes maintain UL94 V-0 compliance, meeting the same material safety standard
• Electrical Parameters: Current rating of 7.5A and voltage ratings of 100V minimum are specified in all substitute models
• Temperature Range: Operating temperature capability from -55°C minimum is present in all substitutes
• Mounting Configuration: The main part features panel mount with cable-side flange, while three HARTING substitutes feature free-hanging in-line configuration with housing/shell flange, and the Hirose substitute maintains panel mount configuration

Key Distinction: The mounting type represents the primary functional difference between the main part and the HARTING substitutes, which employ free-hanging in-line termination rather than panel mount.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Recommended for Equivalent Functionality)

The Hirose Electric HDEB-9PF(05) maintains panel mount configuration equivalent to the main part and provides ROHS3 compliance. This connector is suitable for applications requiring panel mounting. However, the operating temperature range of -40°C to 85°C is more restrictive than the L777DFEH09P, and the current rating is 3A compared to 7.5A.

The HARTING substitutes (09641217210, 09641217230, 09641217240) employ free-hanging in-line mounting architecture, requiring different mechanical integration than the panel mount main part. These connectors are suitable for applications using cable-side integration and provide equivalent 7.5A current rating with ROHS3 compliance. Selection among the three HARTING variants is determined by shell finish material requirements: 09641217210 and 09641217230 feature plain steel shell finish, while 09641217240 includes tin-plated shell matching the main part specification.

Voltage and Temperature Considerations

Applications requiring the full 300V rating of the L777DFEH09P or operating temperatures exceeding 125°C find no exact substitutes within the provided list. The HARTING connectors are rated at 100V, while the Hirose unit is rated at 400V. Applications requiring temperatures above 125°C or below -40°C must verify the main part L777DFEH09P availability or seek additional alternatives outside the provided substitute list.

Frequently Asked Questions (FAQ)

Q: Can the HARTING 09641217210, 09641217230, or 09641217240 directly replace the L777DFEH09P in a panel mount application?

A: The HARTING substitutes feature free-hanging in-line mounting rather than panel mount configuration. Direct mechanical replacement is not possible without redesign of the mounting interface. These parts are suitable for cable-side assembly applications only.

Q: What is the difference between HARTING part numbers 09641217210, 09641217230, and 09641217240?

A: The three HARTING parts are electrically and mechanically identical with one exception: shell material finish. Parts 09641217210 and 09641217230 feature plain steel shells, while part 09641217240 includes tin-plated steel finish matching the L777DFEH09P specification. All three share identical current ratings, voltage ratings, temperature ranges, and contact materials (copper alloy).

Q: Is the Hirose HDEB-9PF(05) suitable for high-temperature applications?

A: The Hirose connector operates from -40°C to 85°C, which is more restrictive than the L777DFEH09P range of -55°C to 155°C. Applications requiring operation below -40°C or above 85°C cannot use this substitute.

Q: What is the current-carrying capacity difference between the main part and Hirose substitute?

A: The L777DFEH09P is rated for 7.5A, while the Hirose HDEB-9PF(05) is rated for 3A. Applications requiring current capacity above 3A must use either the main part or the HARTING substitutes.

Q: Are all substitutes RoHS compliant?

A: Yes. The main part L777DFEH09P carries RoHS Compliant status, while all substitute parts (HARTING 09641217210, 09641217230, 09641217240, and Hirose HDEB-9PF(05)) are ROHS3 Compliant. All meet environmental regulatory requirements.

Q: What is the key difference between the three HARTING substitutes and the main Amphenol part?

A: The primary difference is mounting configuration. The Amphenol L777DFEH09P employs panel mount with cable-side flange, while the HARTING substitutes use free-hanging in-line mounting with housing/shell flange. Electrical specifications including current rating (7.5A) and material flammability remain equivalent between the main part and HARTING options.
