Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the 3M 300-032-050 is determined by the following critical parameters:

• Position Count & Configuration: 32 positions in 1 x 32 arrangement
• Pitch Specifications: 0.100" (2.54mm) mating and post pitch
• Mounting Technology: Through-hole mounting requirement
• Contact Interface: Gold-plated mating surface for reliable electrical connection
• Physical Form Factor: SIP socket configuration

The Mill-Max 346-43-132-41-013000 satisfies all substitution criteria through matching position count, pitch specifications, mounting type, and mating contact finish. This part maintains functional and mechanical compatibility with the original 3M component.

Parameter Comparison

Engineering Selection Recommendations

The Mill-Max 346-43-132-41-013000 is the qualified substitute for the obsolete 3M 300-032-050. Selection is based on:

• Product Status: The Mill-Max part is active and currently available, addressing the obsolescence of the original 3M component
• Compliance: The substitute meets ROHS3 compliance requirements and maintains REACH unaffected status
• Functional Equivalence: Matching position count, pitch, mounting type, and mating contact finish ensure direct compatibility in existing applications
• Electrical Specifications: The substitute provides specified current rating (3 A) and operating temperature range (-55°C ~ 125°C), supporting standard through-hole socket applications

Frequently Asked Questions (FAQ)

Q: What makes the Mill-Max 346-43-132-41-013000 a suitable substitute for the 3M 300-032-050?

A: Both parts share identical position count (32), pitch specifications (0.100" / 2.54mm), mounting type (through-hole), and mating contact finish (gold). These parameters define functional and mechanical compatibility for SIP socket applications.

Q: Are there differences in contact finish thickness between the two parts?

A: Yes. The 3M part specifies 8.00µin (0.203µm) gold plating on mating contacts, while the Mill-Max substitute provides 30.0µin (0.76µm). The thicker plating on the substitute enhances durability and contact reliability.

Q: What is the packaging difference?

A: The 3M 300-032-050 packaging is not specified in available data. The Mill-Max 346-43-132-41-013000 is supplied in tube packaging.

Q: Does the Mill-Max part meet current regulatory requirements?

A: Yes. The Mill-Max 346-43-132-41-013000 is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: Can the Mill-Max substitute be used in applications requiring specific operating temperature ranges?

A: The Mill-Max part operates across -55°C ~ 125°C, suitable for standard industrial and commercial through-hole socket applications. Verify application temperature requirements against this specification.
