3M 500-032-050 SIP Socket - Equivalent & Substitute Parts

Part Overview

The 3M 500-032-050 is a 32-position single inline package (SIP) socket with gold-plated mating contacts, designed for through-hole mounting applications. This connector accommodates 32 pins in a 1 x 32 configuration with 0.100" (2.54mm) pitch spacing. The product is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

The Mill-Max Manufacturing Corp. part number 714-93-132-31-018000 qualifies as a direct substitute based on the following critical parameters:

• Position Count & Configuration: Both parts feature 32 positions in a 1 x 32 SIP arrangement
• Pitch Spacing: Both maintain 0.100" (2.54mm) mating pitch, ensuring mechanical and electrical compatibility with standard SIP pin headers
• Mounting Method: Both are through-hole mounted connectors
• Mating Contact Finish: Both provide gold-plated mating contacts for reliable electrical connection
• Moisture Sensitivity: Both are classified as MSL 1 (Unlimited), indicating equivalent environmental tolerance

The substitute part is currently in active production status with improved specifications including higher contact finish thickness on mating surfaces (30.0µin vs. 8.00µin) and defined operating temperature range (-55°C ~ 125°C).

Parameter Comparison

Engineering Selection Recommendations

The Mill-Max 714-93-132-31-018000 is the designated substitute for the obsolete 3M 500-032-050. Selection is based on:

• Product Status: The substitute is in active production, ensuring long-term availability and supply chain continuity
• Compliance: Both parts share identical ECCN (EAR99) and HTSUS classifications, maintaining regulatory consistency
• RoHS Compliance: The substitute is ROHS3 compliant, meeting current environmental standards
• Mechanical Compatibility: Identical pitch spacing and position count ensure direct mechanical fit in existing PCB designs
• Electrical Compatibility: Gold-plated mating contacts on both parts provide equivalent electrical performance for signal integrity

The substitute offers enhanced durability through increased contact finish thickness on mating surfaces, providing improved wear resistance and contact reliability over the original design.

Frequently Asked Questions (FAQ)

Q: Can the Mill-Max 714-93-132-31-018000 be used as a direct replacement in existing designs using the 3M 500-032-050?

A: Yes. Both parts share identical position count (32), pitch spacing (0.100"), mounting method (through-hole), and mating contact finish (gold). PCB footprints and mating connectors designed for the 3M part are mechanically and electrically compatible with the Mill-Max substitute.

Q: What is the difference in contact finish thickness between the two parts?

A: The Mill-Max substitute provides 30.0µin (0.76µm) gold plating on mating contacts compared to 8.00µin (0.203µm) on the original 3M part. This increased thickness enhances contact durability and wear resistance in high-cycle mating applications.

Q: Are there packaging differences between these parts?

A: The 3M 500-032-050 packaging is not specified in available documentation. The Mill-Max 714-93-132-31-018000 is supplied in tube packaging. Verify packaging requirements for your procurement and assembly processes.

Q: Does the operating temperature specification affect substitution suitability?

A: The Mill-Max substitute specifies an operating temperature range of -55°C ~ 125°C. The original 3M part does not provide this specification. If your application operates within this range, the substitute is suitable. For applications outside this range, verify compatibility with the original design requirements.

Q: Are both parts RoHS compliant?

A: The Mill-Max 714-93-132-31-018000 is ROHS3 compliant. RoHS status for the 3M 500-032-050 is not specified in available documentation. Verify RoHS requirements for your application and supply chain.
