L77DA15SOL2VF
Part Overview
The L77DA15SOL2VF is a 15-position D-Sub receptacle connector manufactured by Amphenol ICC (Commercial Products). This through-hole solder-terminated connector features female sockets with tin-plated steel shell and gold-plated contacts. The component is currently in active production status with 664 units available in inventory.
Finding alternative models becomes necessary when the primary part is unavailable, when design requirements demand specific mounting configurations, or when substitution criteria such as shell material finish, flange design, or contact current rating must be accommodated for application compatibility.

Substitute Part Grouping Explanation
Substitution of the L77DA15SOL2VF is determined by strict adherence to electrical and mechanical parameters. Compatible substitute parts must satisfy the following requirements:
Critical Parameters for Substitution:
- Connector Type: D-Sub receptacle with female sockets
- Number of Positions: 15 positions across 2 rows
- Shell Size/Layout: 2 (DA, A) configuration
- Termination Method: Solder
- Contact Type: Signal contacts
- Material Flammability: UL94 V-0 rated
- Connector Style: D-Sub
Acceptable Parameter Variations: Substitutes may differ in the following parameters based on application requirements:
- Mounting Type: Through-hole designs only (vertical or panel mount variations)
- Shell Material Finish: Tin-plated or nickel-plated steel
- Current Rating: 3A to 7.5A (dependent on contact design and material)
- Operating Temperature Range: Minimum -50°C to 100°C or better
- Flange Feature: Housing/shell options or screwlock variations (4-40 standard)
- Contact Material: Brass or phosphor bronze
- Dielectric Material: Thermoplastic or polyamide options
Non-substitutable Parameters:
- Connector position count must remain 15
- Solder termination requirement is fixed
- D-Sub shape and shell size DA/A is mandatory
- UL94 V-0 flammability rating is required
Nine substitute parts from established manufacturers satisfy these criteria with variations in shell finish, contact material, mounting configuration, and thermal performance specifications.

Engineering Selection Recommendations
First Choice - Direct Compatibility: The D15S24A4GV00LF from Amphenol ICC (FCI) offers the closest functional equivalency to the L77DA15SOL2VF. Both connectors are manufactured by Amphenol entities, share identical operating temperature range (-55°C to 125°C), identical voltage rating (300V), matching shell size/layout (2 DA/A), and identical 15-position female socket configuration. Both are RoHS Compliant and active in production. The D15S24A4GV00LF carries a 5A per-contact current rating with tin-nickel plating and phosphor bronze contacts, providing enhanced corrosion resistance compared to standard tin plating.
Secondary Choices - NorComp Series: The 172-E series from NorComp Inc. (172-E15-213R001, 172-E15-213R011, 172-E15-213R021, 172-E15-213R031, 172-E15-213R911) provides active production alternatives with panel mount through-hole configurations. These connectors feature nickel-plated steel shells, offering improved corrosion resistance. All 172-E series parts are ROHS3 Compliant and operate across -50°C to 100°C. Current rating is 5A. These options are suitable when panel-mount geometry and nickel plating are acceptable design variations.
Avoid: The NorComp 172-015 series (172-015-212R001, 172-015-212R911) is obsolete and should not be selected for new designs or long-term availability requirements.
Limited Application Use: The A-DF 15 PP/Z from Assmann WSW Components has a reduced current rating of 3A and limited lower temperature operation (-20°C minimum). This part is suitable only for applications with reduced current demands and operating above -20°C. The TE Connectivity 2-338314-2 operates to 105°C maximum, below the primary part's 125°C specification, and should be evaluated only when maximum temperature requirement does not exceed 105°C.
Frequently Asked Questions (FAQ)
Q: Can I use a D-Sub connector with 9 positions as a substitute for the L77DA15SOL2VF? A: No. The 15-position requirement is non-negotiable. All substitute parts must maintain the 15-position, 2-row (DA/A shell size) configuration for mechanical and electrical compatibility.
Q: What is the critical difference between the L77DA15SOL2VF and the D15S24A4GV00LF? A: The primary difference is the contact material and shell finish. L77DA15SOL2VF uses brass contacts with tin plating. The D15S24A4GV00LF uses phosphor bronze contacts with tin-nickel plating. Both maintain the same 15-position receptacle type, solder termination, operating temperature (-55°C to 125°C), voltage rating (300V), and UL94 V-0 flammability rating. The D15S24A4GV00LF is fully compatible as a replacement.
Q: Why are the NorComp 172-E series parts rated for only 5A when the L77DA15SOL2VF is rated 7.5A? A: Current rating is determined by contact design, material composition, and termination method. The 172-E series employs a different contact geometry optimized for panel-mount applications, resulting in a lower per-contact current handling capacity. Application requirements must verify that 5A rating is acceptable.
Q: Can I use the A-DF 15 PP/Z at -55°C? A: No. The A-DF 15 PP/Z is rated for -20°C to 105°C operation. For applications requiring operation below -20°C, the L77DA15SOL2VF, D15S24A4GV00LF, or TE Connectivity 2-338314-2 must be selected.
Q: What is the difference between through-hole vertical mounting and panel-mount through-hole configurations? A: Through-hole vertical mounting (L77DA15SOL2VF orientation) positions the connector perpendicular to the board surface with solder connection to vertical leads. Panel-mount through-hole (NorComp 172-E series) positions the connector parallel to the board for installation through a panel cutout, with solder pads also on the board. Mounting type directly affects circuit board layout and mechanical enclosure design.
Q: Are all these substitutes RoHS compliant? A: RoHS compliance status varies. L77DA15SOL2VF, D15S24A4GV00LF, and 2-338314-2 are RoHS Compliant. NorComp 172-E series parts are ROHS3 Compliant. The A-DF 15 PP/Z is ROHS3 Compliant. Verify compliance level matches your regulatory requirements.
Q: Why would I choose a substitute if the primary part is in stock? A: Substitutes become relevant for design flexibility, performance optimization (such as nickel plating for corrosion resistance), specific mounting requirements, or future supply chain contingency planning when primary part availability becomes constrained.
