300-032-000 SIP Socket Equivalent & Substitute Parts

Part Overview

The 3M 300-032-000 is a 32-position SIP (Single In-line Package) socket with gold-plated contacts designed for through-hole mounting on printed circuit boards. This component functions as an IC socket for 32-pin DIP packages, providing a removable connection interface between integrated circuits and PCB traces.

The 300-032-000 is currently available with 785 pieces in new original stock. Due to the discontinuation of certain connector families and evolving manufacturing standards, equivalent substitute parts may be required for new designs or when original inventory becomes unavailable.

Key Parameters

Substitute Part Grouping Explanation

The Mill-Max Manufacturing Corp. part number 310-93-132-41-001000 qualifies as a substitute based on the following critical parameters:

• Number of Positions: Both parts accommodate 32 positions
• Contact Finish: Both feature gold-plated mating contacts
• Pitch Specification: Both use 0.100" (2.54mm) standard pitch for DIP package compatibility
• Mounting Configuration: Both are through-hole mounted on PCBs
• Contact Type: Both provide female socket receptacles for IC pin insertion
• Electrical Rating: Both support 3A current and 100V–150VDC voltage specifications
• Operating Temperature Range: Both operate across -55°C to 125°C
• Compliance: Both meet UL94 V-0 flammability and RoHS3 requirements

The 310-93-132-41-001000 is classified as a receptacle connector rather than a dedicated IC socket, but its electrical and mechanical specifications align with the functional requirements of the 300-032-000 for 32-pin DIP applications.

Parameter Comparison

Engineering Selection Recommendations

The Mill-Max 310-93-132-41-001000 is suitable as a substitute for the 3M 300-032-000 in applications requiring a 32-position, 0.100" pitch through-hole connector with gold-plated contacts. Both parts meet UL94 V-0 flammability requirements and RoHS3 compliance standards.

The Mill-Max part is currently discontinued at DiGi Electronics. Designers should verify long-term availability through alternative distributors before committing to this substitute in production designs. The 3M 300-032-000 remains available with adequate stock levels (785 pieces) and should be prioritized for new designs when supply permits.

Frequently Asked Questions (FAQ)

Q: Can the Mill-Max 310-93-132-41-001000 directly replace the 3M 300-032-000 in existing PCB designs?

A: Yes, provided the PCB footprint accommodates the 0.100" (2.54mm) pitch and through-hole solder termination. Both parts use identical pitch specifications and mounting methods. Physical dimensions should be verified against the original design specifications.

Q: What is the primary functional difference between these parts?

A: The 3M 300-032-000 is a dedicated IC socket designed for removable IC insertion and removal cycles. The Mill-Max 310-93-132-41-001000 is a receptacle connector intended for board-to-board or permanent connections. Both provide equivalent electrical and mechanical connectivity for 32-pin DIP packages.

Q: Are there compliance or certification differences between these parts?

A: Both parts meet UL94 V-0 flammability standards and RoHS3 compliance. The Mill-Max part specifies MSL 1 (Unlimited) moisture sensitivity, indicating no moisture precautions are required during storage or handling.

Q: What electrical parameters should be verified for substitution?

A: Confirm that the application does not exceed 3A current or 150VDC voltage ratings. Both parts support these specifications. Operating temperature range (-55°C to 125°C) must also align with application requirements.

Q: Is the gold contact finish thickness critical for substitution?

A: The Mill-Max part specifies 30.0µin (0.76µm) mating contact finish thickness. This thickness is standard for gold-plated connectors and provides adequate wear resistance for typical IC socket applications. The 3M part does not specify this parameter, but both are functionally equivalent for standard DIP package use.
