Engineering Selection Recommendations

Primary Recommendation: TE Connectivity 5747845-3

The TE Connectivity 5747845-3 is the preferred substitute for the obsolete 788757-1. Both components are manufactured by TE Connectivity and belong to the AMPLIMITE HD-20 series, ensuring design continuity. The 5747845-3 is active in production status and RoHS compliant, addressing regulatory requirements. The primary electrical difference is the increased current rating (6A versus 2A) and reduced voltage rating (125V versus 250V). The 5747845-3 includes a ground strap feature and tin-plated shell finish, providing enhanced performance characteristics. Inventory availability is substantial at 1667 pieces.

Secondary Recommendations: HARTING 09682535611, 09682535612, 09682535613, 09682537611, 09682537612, 09682537613

The HARTING series connectors (096825356xx and 096825376xx) provide active, ROHS3-compliant alternatives with higher current ratings (6.5A) and extended operating temperature range (-55°C to 125°C). These components differ in flange feature configuration and contact finish specifications. Selection among these variants depends on specific mounting requirements:

Housing/Shell (M3) flange: 09682535611, 09682537611
Housing/Shell (4-40) flange: 09682535612, 09682537612
Mating Side Female Screwlock (4-40) flange: 09682535613, 09682537613

Tertiary Recommendations: NorComp Inc. 182-015-213R161, 182-015-213R171, 182-015-213R181

The NorComp 182 series connectors provide ROHS3-compliant alternatives with panel mount capability in addition to through-hole mounting. These components feature nickel-plated steel shells and gold contact finish. Current rating is 5A with operating temperature range of -55°C to 105°C. Selection among variants depends on flange configuration:

Housing/Shell (Unthreaded) flange: 182-015-213R161
Housing/Shell (4-40) flange: 182-015-213R171
Mating Side Female Screwlock (4-40) flange: 182-015-213R181

All NorComp variants include ground strap features and are available in tray packaging.

Compliance Considerations

The original 788757-1 is RoHS non-compliant. All recommended substitutes are RoHS compliant (either RoHS or ROHS3 status), meeting current regulatory requirements for new designs and production. REACH status is either Vendor Undefined or REACH Unaffected across all alternatives, indicating no known REACH-restricted substances.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 5747845-3 directly replace the 788757-1 in existing designs?

A: The 5747845-3 maintains mechanical and electrical interface compatibility with the 788757-1. Both are 15-position D-Sub receptacles with identical shell size, backset spacing, and solder termination. The 5747845-3 has higher current capacity (6A versus 2A) and lower voltage rating (125V versus 250V). Applications operating below 125V and requiring less than 2A current can use the 5747845-3 as a direct replacement. Applications requiring the full 250V rating require evaluation of alternative substitutes or design modification.

Q: What is the difference between the HARTING 09682535612 and 09682537612 connectors?

A: Both connectors are electrically and mechanically identical 15-position D-Sub receptacles with 6.5A current rating and 4-40 housing/shell flange. The primary difference is in contact finish specification. The 09682535612 specifies Gold or Gold-Palladium contact finish at 30.0µin (0.76µm) thickness. The 09682537612 does not specify contact finish details. Both are ROHS3 compliant and active in production.

Q: Are the NorComp 182 series connectors suitable for applications requiring panel mounting?

A: Yes. The NorComp 182-015-213R161, 182-015-213R171, and 182-015-213R181 connectors support both panel mount and through-hole mounting configurations. This dual-mount capability provides design flexibility for applications requiring either mounting method. The specific flange feature (unthreaded, 4-40 threaded, or female screwlock) determines the mounting interface type.

Q: What is the significance of the flange feature differences among substitute parts?

A: The flange feature determines the mechanical mounting interface on the printed circuit board or panel. Housing/Shell (Unthreaded) flanges provide basic mechanical retention. Housing/Shell (4-40) flanges accept 4-40 threaded fasteners for secure mounting. Mating Side Female Screwlock flanges provide integrated screwlock mechanisms for cable retention. Selection depends on the specific mounting requirements and available board or panel features in the target application.

Q: Do all substitute parts have the same operating temperature range as the 788757-1?

A: No. The 788757-1 operates from -55°C to 105°C. The TE Connectivity 5747845-3 and NorComp 182 series maintain this range. The HARTING 09682535611, 09682535612, 09682535613, 09682537611, 09682537612, and 09682537613 connectors extend the upper operating temperature to 125°C. Applications requiring operation above 105°C must use HARTING alternatives. Applications with maximum operating temperature below 105°C can use any listed substitute.

Q: What packaging options are available for substitute parts?

A: The TE Connectivity 5747845-3 is supplied in tray packaging. HARTING connectors are supplied in bulk packaging. NorComp 182 series connectors are supplied in tray packaging. Packaging selection may affect procurement, handling, and inventory management procedures. Confirm packaging requirements with specific application and supply chain procedures.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts are RoHS compliant (either RoHS or ROHS3 status). The original 788757-1 is RoHS non-compliant. Substitution with any listed alternative provides RoHS compliance for new designs and production runs subject to RoHS regulations.

Q: What is the current rating difference between the 788757-1 and substitute parts?

A: The 788757-1 has a 2A current rating. The TE Connectivity 5747845-3 has 6A rating. The HARTING series has 6.5A rating. The NorComp 182 series has 5A rating. Applications designed for 2A operation can use any substitute without current derating. Applications requiring higher current capacity benefit from HARTING (6.5A) or TE Connectivity (6A) alternatives.
