Engineering Selection Recommendations

Primary Substitutes (HARTING 09681635812 and 09681635813):

The HARTING 09681635812 and 09681635813 connectors are direct functional equivalents to the TE Connectivity 788754-1. Both parts maintain identical mechanical specifications including 9-position D-Sub plug configuration, right-angle through-hole mounting, and 0.318" backset spacing. The HARTING parts provide enhanced electrical performance with 6.5A current rating compared to the original 2A specification, and extended operating temperature range to 125°C. Both parts are ROHS3 compliant and carry active product status, ensuring long-term availability. The primary distinction between these two models is the flange feature: 09681635812 features Housing/Shell (4-40) threading, while 09681635813 includes Mating Side Female Screwlock (4-40) for enhanced connector retention.

Secondary Substitutes (HARTING 09681635811, 09681637811, 09681637813):

The HARTING 09681635811, 09681637811, and 09681637813 connectors provide equivalent mechanical compatibility with identical shell size, position count, and mounting configuration. These parts offer the same performance enhancements as the primary HARTING substitutes with 6.5A current rating and -55°C to 125°C operating range. Selection among these variants depends on specific flange requirements: 09681635811 and 09681637811 feature Housing/Shell (M3) threading, while 09681637813 includes Mating Side Female Screwlock (4-40).

Tertiary Substitutes (NorComp 182-009 Series):

The NorComp 182-009-113R161, 182-009-113R171, 182-009-113R181, 182-009-113R431, and 182-009-113R451 connectors maintain full mechanical and electrical compatibility with the original TE Connectivity part. These connectors feature identical 9-position D-Sub plug configuration, right-angle solder termination, and 0.318" backset spacing. The NorComp parts are rated for 5A current capacity and operate across the same -55°C to 105°C temperature range as the original part. All NorComp variants are ROHS3 compliant with active product status. Flange feature variations include Housing/Shell (Unthreaded), Housing/Shell (4-40), and Mating Side Female Screwlock (4-40) options. NorComp parts include either Ground Strap or Grounding Indents features depending on variant selection.

Compliance Considerations:

All identified substitute parts are ROHS3 compliant, addressing the RoHS non-compliance status of the obsolete TE Connectivity 788754-1. This compliance upgrade is critical for new designs and applications subject to RoHS regulations. All substitute parts maintain UL94 V-0 flammability rating and are classified as EAR99 for export control purposes.

Frequently Asked Questions (FAQ)

Q: Can HARTING 09681635812 directly replace TE Connectivity 788754-1 in existing designs?

A: Yes. The HARTING 09681635812 maintains identical mechanical specifications including 9-position D-Sub plug configuration, right-angle through-hole mounting, 0.318" backset spacing, and UL94 V-0 flammability rating. The connector will mate with existing D-Sub receptacles designed for DE/E shell size. The enhanced 6.5A current rating and extended -55°C to 125°C operating temperature provide improved performance margins over the original 2A, 250V specification.

Q: What is the difference between HARTING 09681635812 and 09681635813?

A: Both connectors are mechanically and electrically identical with the same 9-position D-Sub plug configuration, 6.5A current rating, and -55°C to 125°C operating range. The primary difference is the flange feature: 09681635812 includes Housing/Shell (4-40) threading for board-level mounting, while 09681635813 includes Mating Side Female Screwlock (4-40) for enhanced connector retention during mating operations. Selection depends on the specific mounting and retention requirements of the application.

Q: Are NorComp 182-009 series connectors compatible with HARTING substitutes?

A: Yes. All NorComp 182-009 series connectors and HARTING substitutes maintain identical D-Sub 9-position plug configuration, right-angle solder termination, and 0.318" backset spacing. These connectors are mechanically and electrically interchangeable and will mate with the same D-Sub receptacle connectors. Selection between manufacturers depends on flange feature requirements, current rating needs (NorComp 5A versus HARTING 6.5A), and operating temperature range specifications.

Q: Does the NorComp 182-009-113R431 include Ground Strap features?

A: No. The NorComp 182-009-113R431 includes Grounding Indents only. The NorComp 182-009-113R161, 182-009-113R171, and 182-009-113R181 variants include both Ground Strap and Grounding Indents features. Selection of the appropriate variant depends on whether ground strap functionality is required for the application.

Q: What is the significance of the flange feature variations in substitute parts?

A: Flange features determine the mounting and retention method for the connector on the circuit board. Housing/Shell (Unthreaded) provides basic board-level mounting. Housing/Shell (4-40) includes threaded mounting holes for secure fastening. Mating Side Female Screwlock (4-40) provides threaded retention on the mating connector interface for enhanced mechanical stability during repeated mating cycles. Selection depends on the specific mechanical requirements and retention specifications of the application.

Q: Are all substitute parts RoHS compliant?

A: Yes. All identified HARTING and NorComp substitute parts are ROHS3 compliant, addressing the RoHS non-compliance status of the obsolete TE Connectivity 788754-1. This compliance upgrade is essential for applications subject to RoHS regulations and for new product designs.

Q: What is the packaging difference between HARTING and NorComp substitutes?

A: HARTING substitute parts are supplied in Bulk packaging, while NorComp substitute parts are supplied in Tray packaging. Packaging selection may affect inventory management and component handling procedures but does not impact electrical or mechanical performance.

Q: Can substitute parts with higher current ratings be used in applications rated for 2A?

A: Yes. Substitute parts with higher current ratings (HARTING 6.5A or NorComp 5A) are suitable for applications originally rated for 2A. The higher current rating provides additional performance margin and does not negatively impact circuit operation. The connector will safely handle the lower current requirements of the original application.
