L77DFE09SVF D-Sub 9-Position Receptacle Connector Equivalent & Substitute Parts

Part Overview

The L77DFE09SVF is a 9-position D-Sub receptacle connector manufactured by Amphenol ICC (Commercial Products). This panel-mount, through-hole solder connector features female sockets with a mating-side female screwlock flange and is designed for signal applications requiring reliable electrical connections in industrial and commercial environments. The part maintains active product status with 958 units in current inventory.

Substitute parts are identified when design requirements permit alternative mounting configurations, termination methods, or packaging formats while maintaining electrical and mechanical compatibility within the D-Sub connector category.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the L77DFE09SVF are identified based on the following criteria:

Electrical Compatibility Parameters:

• Connector style: D-Sub
• Connector type: Receptacle, Female Sockets
• Number of positions: 9
• Number of rows: 2
• Shell size and layout: 1 (DE, E)
• Contact type: Signal
• Contact material: Copper Alloy
• Operating temperature range: -55°C ~ 125°C
• Material flammability rating: UL94 V-0
• RoHS compliance: Required

Mechanical Compatibility Parameters:

• Shell material and finish: Steel, Tin Plated
• Contact finish: Gold
• Current rating: 7.5A per contact
• Moisture sensitivity level: 1 (Unlimited)

Allowable Variations:

• Mounting type: Panel mount (main part) versus free hanging in-line (substitute parts)
• Termination method: Solder (main part) versus solder cup (substitute parts)
• Flange feature: Mating-side female screwlock (main part) versus unthreaded housing/shell (substitute parts)
• Voltage rating: 300V (main part) versus 1000V (substitute parts) — higher voltage rating is acceptable
• Packaging format: Bag (main part) versus tray or bulk (substitute parts)
• Contact finish thickness: Variations in plating thickness are acceptable

The substitute parts DEP09S064TLF and DEP09S065TLF maintain all critical electrical parameters while differing in mounting configuration and termination style, making them suitable alternatives for applications where free-hanging in-line mounting and solder cup termination are acceptable.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (L77DFE09SVF): Select the L77DFE09SVF when panel-mount, through-hole solder termination with mating-side female screwlock flange is required. This configuration is suitable for applications requiring fixed panel installation with direct PCB or chassis mounting.

Substitute Part Selection (DEP09S064TLF or DEP09S065TLF): Select DEP09S064TLF or DEP09S065TLF when free-hanging in-line mounting with solder cup termination is acceptable. These parts are suitable for applications requiring flexible wire harness integration or cable assembly configurations.

Compliance and Certification Basis: All three parts maintain active product status, RoHS compliance, UL94 V-0 flammability rating, and unlimited moisture sensitivity level (MSL 1). All parts are manufactured by Amphenol ICC and meet the same electrical and environmental specifications within their respective mounting and termination categories.

Voltage Rating Consideration: The substitute parts (DEP09S064TLF and DEP09S065TLF) feature a 1000V voltage rating compared to the 300V rating of the main part. This higher voltage capability does not restrict substitution in applications designed for 300V operation.

Frequently Asked Questions (FAQ)

Q: Can DEP09S064TLF or DEP09S065TLF be used as direct replacements for L77DFE09SVF?

A: Direct replacement depends on application requirements. The substitute parts maintain identical electrical specifications (9-position, 2-row, D-Sub receptacle, female sockets, 7.5A current rating, copper alloy contacts with gold finish, -55°C to 125°C operating range, UL94 V-0 rating, RoHS compliance). However, they differ in mounting type (free-hanging in-line versus panel mount) and termination method (solder cup versus solder). Substitution is valid only when the application design permits these mechanical differences.

Q: What is the difference between DEP09S064TLF and DEP09S065TLF?

A: Both parts are electrically and mechanically identical 9-position D-Sub receptacles with free-hanging in-line mounting and solder cup termination. The primary differences are packaging format (DEP09S064TLF supplied in tray; DEP09S065TLF supplied in bulk) and contact finish thickness (DEP09S064TLF has flash plating; DEP09S065TLF has 30.0µin/0.76µm plating). Both maintain the same electrical performance and compliance certifications.

Q: Are the substitute parts compatible with the same mating connectors as L77DFE09SVF?

A: Yes. All three parts are 9-position D-Sub receptacles with shell size 1 (DE, E) configuration and female sockets. They are compatible with standard D-Sub 9-position male plugs designed for this shell size and layout.

Q: What are the key electrical parameters that remain constant across all three parts?

A: The following parameters are identical across L77DFE09SVF, DEP09S064TLF, and DEP09S065TLF: connector style (D-Sub), connector type (receptacle, female sockets), number of positions (9), number of rows (2), shell size and layout (1 DE, E), contact type (signal), shell material and finish (steel, tin plated), contact material (copper alloy), contact finish (gold), current rating (7.5A per contact), operating temperature range (-55°C to 125°C), material flammability rating (UL94 V-0), RoHS compliance status, and moisture sensitivity level (1 unlimited).

Q: Why do the substitute parts have a higher voltage rating (1000V versus 300V)?

A: The substitute parts are designed for applications requiring higher voltage capability. The higher voltage rating does not restrict their use in 300V applications. Selection should be based on application voltage requirements and mechanical compatibility (mounting type and termination method).

Q: What packaging options are available?

A: L77DFE09SVF is supplied in bag packaging (958 units in stock). DEP09S064TLF is supplied in tray packaging (1234 units in stock). DEP09S065TLF is supplied in bulk packaging (1069 units in stock). Packaging selection should be based on inventory management and assembly process requirements.

Q: Are all three parts RoHS compliant?

A: Yes. L77DFE09SVF, DEP09S064TLF, and DEP09S065TLF are all RoHS compliant. DEP09S064TLF and DEP09S065TLF also carry REACH unaffected status.
