L77DFA15SOL2RM8 D-Sub Receptacle Equivalent & Substitute Parts

Part Overview

The L77DFA15SOL2RM8 is a 15-position D-Sub receptacle connector manufactured by Amphenol ICC (Commercial Products). This panel-mount, solder-terminated connector features female sockets with a 2-row (DA, A) shell size configuration. The connector is designed for signal applications with a current rating of 7.5A and operates across a temperature range of -55°C to 125°C. The part is active in production status and RoHS compliant.

Equivalent and substitute parts are identified based on matching core electrical and mechanical parameters: 15-position configuration, 2-row layout, D-Sub connector style, receptacle type with female sockets, solder termination, and signal contact type. Substitutes must maintain compatibility with the shell size (DA, A) and operating specifications.

Engineering Selection Recommendations

All listed substitute parts maintain active production status and meet the core functional requirements of the L77DFA15SOL2RM8. Selection among substitutes depends on specific application constraints:

Full Electrical and Thermal Compatibility: The Amphenol ICC (FCI) Delta D series parts (D15S24A4GV00LF, D15S24A4GX00LF, D15S24A4PA00LF, D15S24A6GX00LF, D15S24B4GV00LF, D15S24B4GX00LF, D15S24B6PA00LF) provide complete compatibility with the original part's operating temperature range (-55°C to 125°C) and voltage rating (300V). These parts are RoHS compliant and maintain the UL94 V-0 flammability rating. Current rating per contact is 5A, which is lower than the original 7.5A specification; applications requiring the full 7.5A rating must account for this reduction.

Limited Temperature Range Compatibility: The TE Connectivity 2-338314-2 operates to 105°C maximum, limiting its use in applications requiring the full -55°C to 125°C range. The Assmann WSW A-DF 15 PP/Z operates to 105°C maximum and carries a 250V voltage rating, making it unsuitable for applications requiring 300V operation. The A-DF 15 PP/Z also carries a 3A current rating, significantly lower than the original specification.

Compliance Considerations: All substitute parts are RoHS compliant. The Amphenol ICC (FCI) Delta D series includes both RoHS and ROHS3 compliant variants. The Assmann WSW A-DF 15 PP/Z is ROHS3 compliant. Selection should align with specific regulatory requirements for the target application.

Mounting Configuration: The original L77DFA15SOL2RM8 specifies panel mount with through-hole termination. Substitute parts are through-hole mounted but do not specify panel mount features. Flange configurations vary among substitutes (mating side screwlock, housing shell threaded, or unthreaded). Physical mounting compatibility must be verified against the specific application PCB layout and enclosure design.

Frequently Asked Questions (FAQ)

Q: Can the D15S24 series parts directly replace the L77DFA15SOL2RM8?

A: The D15S24 series parts (D15S24A4GV00LF, D15S24A4GX00LF, D15S24A4PA00LF, D15S24A6GX00LF, D15S24B4GV00LF, D15S24B4GX00LF, D15S24B6PA00LF) are functionally compatible as 15-position D-Sub receptacles with matching shell size, solder termination, and operating temperature range. However, the current rating per contact is 5A compared to the original 7.5A. Applications operating at or near the 7.5A specification must account for this reduction in current capacity.

Q: What is the difference between the various D15S24 part numbers?

A: The D15S24 series variants differ in flange feature design and contact finish thickness. Parts designated with "A4GV" or "B4GV" feature mating side female screwlock (4-40). Parts with "A4GX" or "B4GX" feature housing shell (4-40) threaded. Parts with "A4PA" or "B6PA" feature housing shell unthreaded. The "A" versus "B" designation indicates different contact finish thickness specifications. All variants maintain the same electrical ratings and operating temperature range.

Q: Is the TE Connectivity 2-338314-2 suitable for high-temperature applications?

A: The TE Connectivity 2-338314-2 operates to a maximum of 105°C, which is 20°C lower than the original L77DFA15SOL2RM8 specification of 125°C. This part is not suitable for applications requiring operation at temperatures above 105°C.

Q: Why does the Assmann WSW A-DF 15 PP/Z have a lower current rating?

A: The A-DF 15 PP/Z carries a 3A current rating, which is significantly lower than the original 7.5A specification. This reflects differences in contact design and material composition. This part is suitable only for applications with current requirements of 3A or less.

Q: Are all substitute parts RoHS compliant?

A: All listed substitute parts are RoHS compliant. Some variants are specifically ROHS3 compliant. Regulatory requirements for the target application should determine whether standard RoHS or ROHS3 compliance is required.

Q: What is the significance of the contact finish thickness variations?

A: Contact finish thickness is specified in microinches (µin) or micrometers (µm). The original L77DFA15SOL2RM8 specifies 20.0µin (0.51µm). Substitute parts specify either "Flash" finish or 30.0µin (0.76µm). These variations affect contact durability and mating cycle life. Applications with high mating cycle requirements should consider finish thickness specifications.

Q: Can I use the A-DF 15 PP/Z in a 300V application?

A: No. The A-DF 15 PP/Z is rated for 250V maximum, making it unsuitable for applications requiring 300V operation. The original L77DFA15SOL2RM8 and most D15S24 series substitutes are rated for 300V.

Q: What mounting differences exist between the original part and substitutes?

A: The original L77DFA15SOL2RM8 specifies panel mount with through-hole termination. Substitute parts are through-hole mounted but vary in flange configuration. Physical compatibility with the specific PCB layout and enclosure design must be verified before selection.

Q: Are there inventory considerations for substitute selection?

A: Inventory levels vary significantly among substitutes. The D15S24A4GV00LF has the highest inventory at 35,497 pieces. Other D15S24 variants range from 1,110 to 1,633 pieces. The TE Connectivity 2-338314-2 has 1,760 pieces, and the Assmann WSW A-DF 15 PP/Z has 1,709 pieces. Availability should be confirmed for production requirements.
