Key Parameters

Substitute Part Grouping Explanation

Substitution of the 794421-1 is based on the following critical parameters that must align for functional compatibility:

Primary Substitution Criteria:

• Socket contact type (pin or socket configuration)
• Crimp termination method
• Wire gauge compatibility (16-18 AWG range)
• RoHS3 compliance
• MSL rating of 1 (Unlimited)

The substitute part 1586841-2 shares the core functional characteristics of the main part: socket contact configuration, crimp termination, and RoHS3 compliance. However, the substitute operates within a narrower wire gauge specification (16 AWG only, versus 16-18 AWG) and features a gold contact finish with specified thickness (30.0µin / 0.76µm) instead of tin. The substitute is classified as active product status, ensuring ongoing availability and support.

Parameter Comparison

Engineering Selection Recommendations

For 794421-1 Replacement:

The substitute part 1586841-2 is suitable for applications requiring socket contact connectors with crimp termination. Both parts maintain ROHS3 compliance and MSL rating of 1, ensuring compatibility with standard manufacturing and storage environments.

Considerations for Selection:

The primary difference between the main part and substitute is the wire gauge specification. The 794421-1 accommodates 16-18 AWG wire, while the 1586841-2 is specified for 16 AWG only. Applications utilizing 18 AWG wire require confirmation that the substitute contact geometry accommodates this wire gauge, or alternative solutions must be evaluated.

The contact finish differs between parts: tin on the main part versus gold on the substitute. Gold plating provides enhanced corrosion resistance and contact reliability in certain environmental conditions. The substitute's gold finish is specified at 30.0µin (0.76µm) thickness.

The substitute part is classified as active product status, ensuring continued availability, technical support, and manufacturing consistency. The main part's obsolete status necessitates transition planning for long-term supply chain management.

Frequently Asked Questions (FAQ)

Q: Can 1586841-2 directly replace 794421-1 in all applications?

A: Direct replacement depends on wire gauge requirements. The 1586841-2 is specified for 16 AWG wire only, while the 794421-1 accommodates both 16-18 AWG. Applications using 18 AWG wire require evaluation of the substitute's contact geometry or identification of alternative solutions.

Q: What is the significance of the contact finish difference (tin versus gold)?

A: Contact finish affects electrical performance and environmental resistance. Tin provides cost-effective performance in standard applications. Gold plating, specified at 30.0µin (0.76µm) on the substitute, offers superior corrosion resistance and contact reliability in demanding environments. Selection depends on application requirements.

Q: Why is product status important in component selection?

A: The 794421-1 is classified as obsolete, indicating discontinued manufacturing and limited availability. The substitute 1586841-2 is active, ensuring ongoing production, consistent quality, and technical support. Active status is preferred for new designs and long-term supply chain stability.

Q: Are both parts RoHS3 compliant?

A: Yes, both 794421-1 and 1586841-2 are ROHS3 compliant and carry MSL rating of 1 (Unlimited), meeting standard environmental and moisture sensitivity requirements.

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

A: The 1586841-2 is supplied in Tape & Reel (TR) packaging format, suitable for automated assembly processes. The main part packaging format is not specified in available documentation.

Q: How do the series designations affect compatibility?

A: The 794421-1 belongs to the AMP-DUAC series, while the 1586841-2 belongs to the VAL-U-LOK series. Series designation indicates different connector families with distinct mechanical and electrical characteristics. Compatibility must be verified based on mating connector specifications and application requirements.
