Parameter Comparison

Engineering Selection Recommendations

Primary Selection Criteria:

All substitute parts (09662116503, 09662117503, 09662556513) are functionally equivalent to the L77DA15SV for 15-position D-Sub receptacle applications. Selection between the main part and substitutes is based on the following engineering factors:

Current Rating Consideration: The L77DA15SV carries a 7.5A current rating, while all HARTING substitutes are rated at 6.5A. For applications requiring the full 7.5A capacity, the L77DA15SV is the appropriate selection. For applications operating at or below 6.5A, HARTING substitutes provide equivalent functionality.

Compliance and Certification: All parts maintain UL94 V-0 material flammability rating and operate across the identical temperature range (-55°C to 125°C). The L77DA15SV holds RoHS Compliant status, while HARTING substitutes hold ROHS3 Compliant status. Both compliance levels are acceptable for modern applications. All parts are REACH Unaffected and carry EAR99 ECCN classification.

Contact Finish and Material: The L77DA15SV features gold-plated brass contacts with 8.00µin (0.203µm) thickness specification. HARTING part 09662556513 provides gold contact finish with copper alloy material. HARTING parts 09662116503 and 09662117503 do not specify contact finish but utilize copper alloy contacts. Gold-plated contacts provide enhanced corrosion resistance and are preferred for high-reliability applications.

Dielectric Material: The L77DA15SV uses thermoplastic glass-filled dielectric material. HARTING substitutes employ polybutylene terephthalate (PBT) or polycyclohexylenedimethylene terephthalate (PCT) glass-filled materials. All materials meet UL94 V-0 requirements and are functionally equivalent for signal connector applications.

Flange Feature: The L77DA15SV features an unthreaded housing/shell flange. HARTING substitutes feature mating-side female screwlock (4-40) flanges, providing additional mechanical retention capability. This represents an enhancement rather than a limitation for board-level applications.

Packaging and Inventory: The L77DA15SV is supplied in Tray packaging with 1100 pieces in stock. HARTING substitutes are supplied in Bulk packaging with 733, 787, and 678 pieces in stock respectively. Packaging format selection depends on assembly process requirements.

Frequently Asked Questions (FAQ)

Q: Can HARTING part 09662116503 or 09662117503 be used as a direct replacement for L77DA15SV in high-current applications?

A: These HARTING parts are rated at 6.5A compared to the L77DA15SV's 7.5A rating. For applications requiring the full 7.5A capacity, the L77DA15SV is the specified selection. For applications operating at 6.5A or below, these parts provide equivalent functionality.

Q: What is the difference between the three HARTING substitute parts?

A: All three HARTING parts (09662116503, 09662117503, 09662556513) share identical core specifications: 15-position receptacle, 2-row configuration, through-hole solder termination, and -55°C to 125°C operating range. The primary difference is contact finish: part 09662556513 specifies gold contact finish, while parts 09662116503 and 09662117503 do not specify finish. Part 09662556513 also includes a Board Lock feature and uses PCT dielectric material instead of PBT.

Q: Are the dielectric material differences between L77DA15SV and HARTING substitutes significant?

A: All dielectric materials (thermoplastic glass-filled, PBT glass-filled, and PCT glass-filled) meet UL94 V-0 flammability requirements and are functionally equivalent for signal connector applications. Material selection does not affect electrical performance or mechanical compatibility in standard applications.

Q: Does the female screwlock flange on HARTING parts affect compatibility?

A: The female screwlock (4-40) flange on HARTING substitutes provides additional mechanical retention compared to the unthreaded housing flange on the L77DA15SV. This represents an enhancement for board-level mounting and does not create compatibility issues. The connector footprint and electrical interface remain identical.

Q: What is the significance of the contact form difference (Machined vs. Stamped)?

A: The L77DA15SV uses machined contacts while HARTING substitutes use stamped contacts. Both contact forms are acceptable for signal applications. Machined contacts typically provide slightly higher reliability in high-cycle mating applications, while stamped contacts offer cost efficiency. For standard applications, both forms are functionally equivalent.

Q: Are all parts suitable for RoHS-compliant applications?

A: Yes. The L77DA15SV is RoHS Compliant, and all HARTING substitutes are ROHS3 Compliant. Both compliance levels satisfy modern RoHS requirements. All parts are REACH Unaffected.

Q: What packaging format should be selected for assembly operations?

A: The L77DA15SV is supplied in Tray packaging, suitable for automated pick-and-place assembly. HARTING substitutes are supplied in Bulk packaging. Packaging selection depends on assembly process requirements and handling procedures.

Q: Can these parts be used interchangeably in existing designs?

A: Electrical and mechanical compatibility is confirmed for all listed parts within their specified current ratings. Design verification should confirm that application current requirements do not exceed 6.5A for HARTING substitutes. Mechanical mounting considerations should account for flange feature differences.
