Substitute Part Grouping Explanation

The TE Connectivity AMP Connectors part 345807-1 is identified as a manufacturer-recommended substitute for the Molex 0845900024. Substitution eligibility is determined by the following critical parameters:

Wire gauge compatibility: The substitute supports 14-20 AWG, which encompasses the original 14-18 AWG range, ensuring proper conductor accommodation and termination integrity.

Contact termination method: Both parts utilize crimp termination, maintaining mechanical and electrical connection consistency.

Contact finish: The substitute features tin plating, which differs from the original nickel finish. This represents a material change that must be evaluated for application-specific corrosion resistance and electrical performance requirements.

Regulatory compliance: Both parts meet ROHS3 requirements and carry MSL 1 ratings, confirming environmental and moisture sensitivity equivalence.

Connector category transition: The substitute operates within rectangular connectors rather than circular connectors, indicating a form factor change that may require mechanical redesign of mating interfaces.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 345807-1 is an active product with confirmed ROHS3 compliance and MSL 1 rating, providing regulatory and environmental equivalence to the obsolete Molex 0845900024. The substitute accommodates the original wire gauge specification within its expanded 14-20 AWG range.

Critical design considerations include the contact type transition from socket to pin, which necessitates corresponding changes to mating connector interfaces. The contact finish change from nickel to tin affects corrosion resistance characteristics and must be evaluated against application environment specifications. The termination method change from compression and crimp to crimp-only may impact installation procedures and tooling requirements.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 345807-1 directly replace the Molex 0845900024 in existing assemblies?

A: Direct replacement requires mechanical redesign of the mating connector interface due to the socket-to-pin contact type change and the transition from circular to rectangular connector categories. Electrical compatibility exists within the specified wire gauge range.

Q: What is the significance of the contact finish change from nickel to tin?

A: Contact finish affects corrosion resistance, electrical conductivity, and long-term reliability in specific environmental conditions. Nickel provides superior corrosion resistance in harsh environments, while tin offers cost advantages. Application environment assessment is required to determine suitability.

Q: Are both parts suitable for the same wire gauge applications?

A: The substitute 345807-1 supports 14-20 AWG, which fully encompasses the original 14-18 AWG specification. Wire gauges within the 14-18 AWG range are compatible with both parts.

Q: What packaging format is available for the substitute part?

A: The TE Connectivity 345807-1 is supplied in Cut Tape (CT) packaging, suitable for automated assembly processes.

Q: Do both parts meet the same regulatory and environmental standards?

A: Both parts are ROHS3 compliant and carry MSL 1 (Unlimited) ratings, confirming equivalent regulatory status and moisture sensitivity performance.
