Engineering Selection Recommendations
All substitute parts listed are active products with current manufacturing status, providing design continuity for applications currently using the obsolete TE Connectivity 788753-1.
HARTING Series (09681635812, 09681635813, 09681637813): These connectors provide enhanced current capacity (6.5A versus 2A) and extended operating temperature range (-55°C to 125°C). All three variants are ROHS3 compliant and feature UL94 V-0 flammability rating. The primary distinction among these parts is the flange feature configuration: 09681635812 uses housing/shell mounting, while 09681635813 and 09681637813 feature mating side female screwlock (4-40) configurations. Selection between these variants depends on specific mounting requirements.
NorComp Series 182 (182-009-113R161, 182-009-113R171, 182-009-113R181, 182-009-113R531, 182-009-113R561): These connectors maintain the original operating temperature range (-55°C to 105°C) and offer 5A current capacity. All variants are ROHS3 compliant with UL94 V-0 flammability rating. The series includes panel mount capability in addition to through-hole mounting. Variants differ in flange feature configuration (housing/shell unthreaded, housing/shell 4-40, or mating side female screwlock 4-40) and feature set (ground strap with grounding indents or board lock with grounding indents). Selection depends on mounting interface and grounding requirements.
Mercury United Electronics Series 621 (621-009-260-033, 621-009-260-042): These connectors feature board edge mounting capability with 3A per contact current rating and reduced operating temperature range (-55°C to 85°C). Both variants are ROHS3 compliant with UL94 V-0 flammability rating and include shielding and mounting brackets. The primary distinction is flange feature: 621-009-260-033 uses mating side female screwlock (4-40), while 621-009-260-042 uses housing/shell (4-40) configuration. These parts are suitable for applications requiring board edge mounting and shielded signal integrity.
All substitute parts satisfy the mandatory matching parameters and are suitable for direct replacement in applications where the TE Connectivity 788753-1 is currently specified. Selection among substitute options should be based on specific mounting interface requirements, current capacity needs, and environmental operating conditions.
Frequently Asked Questions (FAQ)
Q: Can the HARTING 09681635813 directly replace the TE Connectivity 788753-1?
A: Yes. Both connectors share identical core specifications: 9-position D-Sub plug configuration, male pins, shell size 1 (DE, E), through-hole right-angle solder termination, 0.318" backset spacing, and UL94 V-0 flammability rating. The HARTING part provides enhanced current capacity (6.5A versus 2A) and extended operating temperature range (-55°C to 125°C). The mating side female screwlock (4-40) flange feature matches the original part configuration.
Q: What is the difference between the NorComp 182-009-113R531 and 182-009-113R561?
A: Both parts are functionally equivalent with identical electrical and mechanical specifications. The primary difference is the flange feature: 182-009-113R531 uses housing/shell (4-40) mounting, while 182-009-113R561 uses mating side female screwlock (4-40) mounting. Selection depends on the specific mounting interface available on the target printed circuit board or panel.
Q: Are the Mercury United Electronics 621-009-260-033 and 621-009-260-042 suitable for all applications using the TE Connectivity 788753-1?
A: These parts are suitable for applications where board edge mounting is available and the reduced operating temperature range (-55°C to 85°C) is acceptable. The 3A per contact current rating is lower than the original 2A specification, but this represents a per-contact rating rather than a total connector rating. The shielded design provides additional signal integrity protection. Confirm mounting interface compatibility before selection.
Q: What does ROHS3 compliance mean for these substitute parts?
A: ROHS3 compliance indicates conformance to the Restriction of Hazardous Substances Directive 2011/65/EU as amended by Directive (EU) 2015/863. All listed substitute parts are ROHS3 compliant, whereas the original TE Connectivity 788753-1 is RoHS non-compliant. This compliance status is relevant for applications subject to European Union regulations or equivalent environmental standards.
Q: Can I use a substitute part with a higher current rating than the original specification?
A: Yes. All substitute parts listed have current ratings equal to or greater than the original 2A specification. Using a connector with higher current capacity does not create compatibility issues and provides design margin for future application modifications. The connector's current rating represents its maximum safe operating capacity; operating at lower currents is always acceptable.
Q: What is the significance of the backset spacing parameter?
A: Backset spacing (0.318" or 8.08mm) defines the distance from the rear of the connector shell to the solder contact termination points. This parameter is critical for printed circuit board layout and component placement. All substitute parts maintain identical backset spacing to the original part, ensuring direct compatibility with existing PCB designs without layout modifications.
Q: Are there differences in contact material between the substitute parts?
A: Yes. The original TE Connectivity 788753-1 uses brass contacts, while HARTING and NorComp variants use copper alloy contacts. Mercury United Electronics parts also use copper alloy contacts. Copper alloy contacts provide equivalent electrical performance and corrosion resistance for signal applications. Contact finish (gold or gold-palladium) is consistent across all parts and provides equivalent protection.
Q: Which substitute part should I select for new designs?
A: For new designs, select from the HARTING series (09681635812, 09681635813, or 09681637813) or NorComp series (182-009-113R variants) based on mounting interface requirements. Both manufacturers offer ROHS3 compliance, extended operating temperature ranges, and higher current capacity. The HARTING series provides the highest current rating (6.5A) and widest operating temperature range (-55°C to 125°C). NorComp variants offer panel mount capability and are available in higher quantities.
