Parameter Comparison

Engineering Selection Recommendations

The 1546350-2 serves as the direct active equivalent to the obsolete 1546350-1. Both parts maintain identical mechanical, material, and functional specifications, ensuring complete interchangeability in CPC connector assemblies.

Product Status Consideration: The 1546350-1 is classified as obsolete, while the 1546350-2 maintains active product status with higher inventory availability (1768 pcs versus 837 pcs). Selection of the active part ensures long-term supply chain reliability.

Regulatory Compliance: The 1546350-2 is ROHS3 compliant, whereas the 1546350-1 is RoHS non-compliant. For applications subject to RoHS regulations, the 1546350-2 is the required selection. Both parts carry identical ECCN (EAR99) and UL94 V-0 flammability ratings.

Packaging Consideration: The 1546350-2 is supplied in bulk packaging, while the 1546350-1 packaging specification is not defined. Bulk packaging typically accommodates higher-volume procurement requirements.

Frequently Asked Questions (FAQ)

Q: Can the 1546350-2 directly replace the 1546350-1 in existing CPC connector assemblies?

A: Yes. The 1546350-2 maintains identical specifications across all mechanical parameters (shell size 23, thread size 1 3/8-18 UNEF, cable opening 0.703", 90° cable exit), material composition (polyamide/nylon), and functional features (clamp screws, cover). Direct substitution is supported without modification.

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

A: The 1546350-1 is obsolete with RoHS non-compliant status, while the 1546350-2 is an active product with ROHS3 compliance. All technical specifications remain identical.

Q: Are there any compatibility issues when transitioning from 1546350-1 to 1546350-2?

A: No compatibility issues exist. Both parts are manufactured by TE Connectivity AMP Connectors within the CPC series and share identical dimensional, material, and functional characteristics.

Q: What does the cable opening specification of 0.703" (17.86mm) indicate?

A: This specification defines the maximum cable diameter that can be accommodated by the cable clamp assembly. Cables within this diameter range are compatible with both backshell variants.

Q: Why is RoHS compliance status different between these parts?

A: The 1546350-2 represents an updated version of the obsolete 1546350-1, incorporating ROHS3 compliance to meet current regulatory requirements. The material composition and functional performance remain unchanged.

Q: What is included with each backshell assembly?

A: Both parts include 7 pieces: 4 cable clamp pieces, 1 flat ring, and 2 screws. This complete assembly supports installation and strain relief functionality.

Q: Is the 1546350-2 available in different packaging options?

A: The 1546350-2 is supplied in bulk packaging. The 1546350-1 packaging specification is not defined in available documentation.
