Substitute Categories:

Direct Equivalent (Active Status): TE Connectivity 1776138-8 maintains identical electrical specifications and mechanical form factor with active product status and RoHS compliance.

Compatible Alternatives (Pitch Variation 5.08mm): Phoenix Contact 1753550 and 1758076, Amphenol PCD ELFH08250 and ELFH08280, and Amphenol Anytek OQ0853500000G provide functional equivalence with minor pitch tolerance variations (0.200" vs. 0.197") and differing shrouding configurations. These parts meet or exceed the electrical requirements of the original component.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: TE Connectivity 1776138-8

The TE Connectivity 1776138-8 is the direct equivalent replacement for the obsolete 796697-8. This part maintains identical pitch (0.197" / 5.00mm), electrical ratings (15 A UL, 300 V UL), operating temperature range (-40°C to 110°C), and mechanical configuration. The 1776138-8 carries active product status and RoHS compliance, making it suitable for new designs and legacy system updates. The primary distinction is housing color (black versus blue) and contact material (copper alloy versus brass), which do not affect electrical or mechanical compatibility.

Secondary Recommendations: Phoenix Contact and Amphenol PCD Parts

Phoenix Contact 1753550 and 1758076, along with Amphenol PCD ELFH08250 and ELFH08280, provide functional alternatives with pitch variations of 0.200" (5.08mm). These parts meet the minimum electrical requirements (12 A UL minimum, 300 V UL) and carry active product status with RoHS3 compliance. The 1758076 and ELFH08250/ELFH08280 feature 4-side shrouding, providing enhanced mechanical protection compared to the 2-side shrouded original design. These alternatives are suitable for applications where pitch tolerance of ±0.08mm is acceptable within the PCB layout constraints.

Tertiary Recommendation: Amphenol Anytek OQ0853500000G

The Amphenol Anytek OQ0853500000G provides a 2-side shrouded configuration matching the original design with a 0.200" (5.08mm) pitch. This part carries active status, ROHS3 compliance, and an extended operating temperature range (-40°C to 115°C). The 12 A UL current rating meets minimum requirements for most applications. This option is suitable when pitch tolerance and shrouding configuration alignment with the original design are prioritized.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1776138-8 be used as a direct replacement for the 796697-8?

A: Yes. The 1776138-8 is a direct equivalent with identical pitch (5.00mm), electrical ratings (15 A UL, 300 V UL), operating temperature range (-40°C to 110°C), and through-hole solder termination. The primary differences are housing color and contact material composition, which do not affect electrical or mechanical compatibility. The 1776138-8 carries active product status and RoHS compliance.

Q: What is the difference between the 0.197" (5.00mm) pitch of the original part and the 0.200" (5.08mm) pitch of some substitute parts?

A: The pitch difference of 0.08mm per position accumulates across the 8-position header, resulting in a total dimensional variance of approximately 0.64mm across the connector. This variation requires PCB layout verification to confirm compatibility with existing footprints. Parts with 5.08mm pitch include Phoenix Contact 1753550, 1758076, Amphenol PCD ELFH08250, ELFH08280, and Amphenol Anytek OQ0853500000G.

Q: Are the 4-side shrouded alternatives (ELFH08250 and ELFH08280) compatible with designs specified for 2-side shrouded connectors?

A: The 4-side shrouded configuration provides additional mechanical protection and may alter the connector's footprint profile. Compatibility depends on available PCB space and mating connector design. The electrical and solder termination characteristics remain equivalent. Physical verification of the mating interface is required before implementation.

Q: What are the RoHS compliance differences among the substitute parts?

A: The original 796697-8 carries "Not applicable" RoHS status due to its obsolete classification. All active substitute parts carry either RoHS Compliant or ROHS3 Compliant status, indicating compliance with current environmental regulations. This compliance is beneficial for new designs and systems subject to RoHS requirements.

Q: Which substitute part has the highest current rating?

A: The TE Connectivity 1776138-8, Amphenol PCD ELFH08250, and ELFH08280 all carry a 15 A UL current rating, matching the original 796697-8. The Phoenix Contact 1753550, 1758076, and Amphenol Anytek OQ0853500000G are rated at 12 A UL, which is suitable for applications requiring 12 A or less.

Q: Can I use parts with different operating temperature ranges as substitutes?

A: Substitution is permissible only when the substitute part's operating temperature range encompasses the application's requirements. The original 796697-8 operates from -40°C to 110°C. The Amphenol PCD parts (ELFH08250, ELFH08280) operate to 105°C, which is within the lower end of the original range. The Amphenol Anytek OQ0853500000G extends to 115°C, exceeding the original specification. Application-specific thermal requirements must be verified.

Q: What is the significance of the contact material differences (brass versus copper alloy)?

A: Both brass and copper alloy contacts provide adequate electrical conductivity and mating durability for terminal block applications. The material composition affects contact resistance characteristics and long-term reliability under specific environmental conditions. Both materials are tin-plated for corrosion resistance. Selection between these materials should be based on application-specific environmental exposure and reliability requirements.

Q: Are there packaging differences among the substitute parts that affect procurement?

A: Yes. The original 796697-8 is listed as obsolete with no current packaging specification. Substitute parts are available in different packaging formats: TE Connectivity 1776138-8 (unspecified), Phoenix Contact 1753550 and 1758076 (Bulk), Amphenol PCD ELFH08250 (Bulk), ELFH08280 (Tray), and Amphenol Anytek OQ0853500000G (Bulk). Packaging selection affects handling, storage, and procurement logistics but does not influence electrical or mechanical performance.
