Engineering Selection Recommendations

The 796381-2 serves as the direct functional equivalent to the 796381-1 across all mechanical, material, and environmental specifications. Selection of 796381-2 is supported by the following factors:

Product Status Transition: The 796381-1 is classified as obsolete, while 796381-2 maintains active product status, ensuring continued availability and manufacturer support.

Regulatory Compliance: The 796381-2 achieves RoHS compliance and REACH unaffected status, whereas the 796381-1 is RoHS non-compliant with vendor-undefined REACH status. This compliance differential is significant for applications subject to environmental and hazardous substance regulations.

Functional Equivalence: All critical mechanical parameters—shell size, thread specification, cable opening diameter, and cable exit angle—are identical between both parts. Material composition, flammability rating, and moisture sensitivity specifications remain unchanged.

Supply Chain Continuity: The 796381-2 maintains higher inventory availability (1368 pcs) compared to the 796381-1 (1045 pcs), supporting consistent procurement and production scheduling.

Frequently Asked Questions (FAQ)

Q: Are the 796381-1 and 796381-2 mechanically interchangeable?

A: Yes. Both parts share identical shell size (17), thread size (15/16-20 UNEF), cable opening (0.453"/11.51mm), and cable exit angle (90°). They are direct mechanical substitutes for CPC series connector applications.

Q: What is the primary difference between these two parts?

A: The 796381-2 is the active production equivalent of the obsolete 796381-1. The 796381-2 achieves RoHS compliance and REACH unaffected status, while the 796381-1 does not meet these regulatory requirements.

Q: Can I use 796381-2 in applications previously specified for 796381-1?

A: Yes. The 796381-2 maintains identical material composition (Polyamide/Nylon), flammability rating (UL94 V-0), and moisture sensitivity level (MSL 1). All functional and environmental characteristics are equivalent.

Q: What is included with each backshell assembly?

A: Both the 796381-1 and 796381-2 include 5 pieces total: 3 cable clamp pieces and 2 screws for assembly and installation.

Q: Does packaging differ between these parts?

A: The 796381-2 is supplied in bulk packaging, while packaging specification for the 796381-1 is not provided in the technical data.

Q: Are there any electrical performance differences?

A: No electrical performance differences exist. Both parts are passive mechanical backshell assemblies with identical material properties and flammability ratings.

Q: Which part should be selected for new designs?

A: The 796381-2 should be selected for new designs due to active product status, RoHS compliance, and REACH unaffected designation, ensuring long-term availability and regulatory alignment.
