Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0473590001 is determined by the following critical parameters:

• Connector Type: Battery Contact (spring contact design)
• Number of Contacts: 4 positions
• Pitch: 0.079" (2.00mm)
• Number of Rows: 1
• Mounting Type: Surface Mount
• Material: Copper Alloy
• Contact Finish: Gold plating
• Contact Finish Thickness: 29.5µin (0.75µm)
• RoHS Compliance: ROHS3 Compliant
• MSL Rating: 1 (Unlimited)

The substitute part Molex 0472861001 meets all these critical parameters, making it functionally equivalent for direct replacement in surface mount battery contact applications.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0472861001 is the direct equivalent substitute for the obsolete Molex 0473590001. Both components share identical electrical and mechanical specifications across all critical parameters. The primary distinction is product status: the 0472861001 is active and currently in production, while the 0473590001 is obsolete.

For new designs or production continuity, the 0472861001 is the appropriate selection. Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment. The 0472861001 is available in Tape & Reel packaging, supporting automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0472861001 directly replace the 0473590001 in existing designs?

A: Yes. The 0472861001 is electrically and mechanically equivalent to the 0473590001. All critical parameters—contact count, pitch, mounting type, material, contact finish, and compliance ratings—are identical.

Q: What is the primary reason for substitution?

A: The 0473590001 is obsolete. The 0472861001 is the active equivalent, ensuring continued component availability and production support.

Q: Are there packaging differences between these parts?

A: The 0473590001 packaging is not specified in the available data. The 0472861001 is supplied in Tape & Reel (TR) packaging, which is standard for automated surface mount assembly.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the 0473590001 and 0472861001 are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) ratings.

Q: What is the contact pitch, and why is it important for substitution?

A: Both parts have a pitch of 0.079" (2.00mm). Pitch is critical for substitution because it determines PCB footprint compatibility and ensures proper mating with corresponding connector housings.
