Engineering Selection Recommendations
Direct Replacement (Preferred): Part 5786143-1 from TE Connectivity AMP Connectors is the primary substitute for 786143-1. This part maintains identical connector specifications, mounting configuration, and termination method while offering active product status and RoHS compliance. The transition from tin-lead to tin plating on the shell does not affect functional compatibility. This part is recommended for new designs and ongoing production requiring direct form-fit-function replacement.
Solder Termination Alternatives: When design requirements permit termination method variation, the following parts provide equivalent 9-position D-Sub receptacle functionality:
-
1757828-1 and 1757830-1 (TE Connectivity Aerospace, Defense and Marine): These military-grade connectors comply with MIL-DTL-24308 specifications and offer extended operating temperature range to 125°C. Both parts maintain ROHS3 compliance and are suitable for applications requiring military-specification connectors.
-
09641127215 (HARTING): This connector provides solder termination with board lock and filter features. Operating temperature extends to 125°C. ROHS3 compliance is confirmed.
-
628-009-220-046 and 628-009-220-047 (Mercury United Electronics): These connectors feature board-side mounting with solder termination, board lock, and shielding. Both maintain ROHS3 compliance and UL94 V-0 flammability rating. Operating temperature range is -55°C to 85°C, which is suitable for applications not requiring the full 105°C upper limit of the original part.
Compliance Considerations: All substitute parts listed are ROHS3 compliant, addressing the RoHS non-compliance status of the obsolete 786143-1. Applications subject to RoHS regulations must transition to one of the listed alternatives.
Frequently Asked Questions (FAQ)
Q: Can 5786143-1 be used as a direct replacement for 786143-1?
A: Yes. Part 5786143-1 maintains identical electrical and mechanical specifications, connector layout, mounting type, and termination method. The primary differences are active product status and improved RoHS compliance. No design modifications are required.
Q: What is the difference between press-fit and solder termination options?
A: The main part 786143-1 uses press-fit termination, which requires specialized press-fit tooling and is suitable for automated assembly. Solder termination alternatives (1757828-1, 1757830-1, 09641127215, 628-009-220-046, 628-009-220-047) require wave or reflow soldering processes. Selection depends on available assembly equipment and manufacturing processes.
Q: Are the Mercury 628 series connectors compatible with the original 786143-1?
A: Mercury 628-009-220-046 and 628-009-220-047 maintain the same 9-position D-Sub shell size and layout. However, they feature board-side mounting flanges instead of mating-side flanges, and solder termination instead of press-fit. These differences require PCB layout modifications. Electrical compatibility is maintained through identical connector layout and contact materials.
Q: What is the operating temperature limitation of the Mercury 628 series substitutes?
A: Mercury parts 628-009-220-046 and 628-009-220-047 operate from -55°C to 85°C, which is 20°C lower than the original 786143-1 specification of -55°C to 105°C. Applications requiring operation above 85°C must use 5786143-1, 09641127215, 1757828-1, or 1757830-1.
Q: Are all substitute parts RoHS compliant?
A: Yes. All listed substitute parts are ROHS3 compliant. The original 786143-1 is RoHS non-compliant due to tin-lead plating. Transition to any substitute part addresses RoHS regulatory requirements.
Q: What packaging options are available for the substitute parts?
A: Part 5786143-1 is supplied in Tray packaging. HARTING 09641127215 is supplied in Bulk packaging. Mercury parts 628-009-220-046 and 628-009-220-047 are supplied in Tray packaging. TE Connectivity military parts 1757828-1 and 1757830-1 are supplied in Bulk packaging. Packaging selection should align with procurement and inventory management requirements.
Q: Can the TE Connectivity military-grade connectors (1757828-1, 1757830-1) be used in commercial applications?
A: Yes. Military-specification connectors exceed commercial requirements and are suitable for commercial applications. These parts offer extended operating temperature range to 125°C and comply with MIL-DTL-24308 standards, providing additional design margin and reliability assurance.
Q: What is the difference between the two TE Connectivity military parts 1757828-1 and 1757830-1?
A: Both parts maintain identical electrical and mechanical specifications, connector layout, and operating parameters. The primary difference is REACH status: 1757828-1 is REACH Affected, while 1757830-1 is Vendor Undefined. For applications subject to REACH regulations, 1757828-1 is the appropriate selection.
