Frequently Asked Questions (FAQ)

Q: Can the 2347330-1 directly replace the 204975 in existing applications?

A: The 2347330-1 matches the 40-position configuration, 0.079" (2.00mm) pitch, through-hole right-angle mounting, and electrical ratings (1.5 A, 500VAC) of the original part. Physical form factor and PCB footprint compatibility must be verified for your specific application.

Q: What is the difference between the Erni and AMP Connectors product lines?

A: Both are TE Connectivity brands. The Erni ERMB08 40 F L1 is obsolete, while the AMP Connectors 2347330-1 is an active product in the Z-PACK series. The substitute maintains equivalent electrical and mechanical specifications.

Q: Are there any compliance differences between the original and substitute parts?

A: The substitute part 2347330-1 is certified ROHS3 Compliant. The original part's compliance status is not documented. For applications requiring specific environmental certifications, verify that ROHS3 compliance meets your requirements.

Q: What is the pitch specification, and why does it matter?

A: Both parts use 0.079" (2.00mm) pitch, which defines the center-to-center spacing between connector positions. This parameter is critical for PCB layout compatibility and must match exactly for direct substitution.

Q: Can I use the 204975 and 2347330-1 interchangeably in inventory?

A: While electrically and mechanically equivalent, the parts are from different product lines. Maintain separate inventory tracking and verify PCB footprint compatibility before mixing parts in production.
