3M 929957-08 Equivalent & Substitute Parts

Part Overview

The 3M 929957-08 is a 2-position shunt connector (1 x 2 grid) with gold-plated contacts, designed for standard 0.100" (2.54mm) pitch applications. This component features an open-top design with female sockets and is constructed from glass-filled polybutylene terephthalate (PBT) housing. The part maintains Active product status and is RoHS compliant with unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling direct functional replacement in PCB applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3M 929957-08 is determined by the following critical parameters:

• Grid Configuration: 2 positions (1 x 2) arrangement
• Pitch Spacing: 0.100" (2.54mm) standard spacing
• Connector Type: Open-top shunt connector with female sockets
• Contact Finish: Gold plating at 30.0µin (0.76µm) thickness
• Flammability Compliance: UL94 V-0 rating
• RoHS Compliance: Compliant status
• MSL Rating: Level 1 (Unlimited)

The TE Connectivity AMP Connectors 390088-1 qualifies as a substitute based on matching grid configuration, pitch, connector type, contact finish specification, flammability rating, RoHS compliance, and MSL rating. Mechanical height variation and housing material differences do not preclude substitution when PCB layout accommodates the dimensional change.

Parameter Comparison

Engineering Selection Recommendations

Both the 3M 929957-08 and TE Connectivity 390088-1 maintain Active product status with full RoHS compliance and UL94 V-0 flammability certification. Selection between these parts should be based on:

• PCB Clearance: The TE Connectivity 390088-1 has a lower profile (0.247" vs. 0.298"), which may be advantageous in space-constrained designs.
• Housing Material Compatibility: The 3M part uses PBT while the TE part uses polyester; both are glass-filled and meet flammability requirements.
• Availability and Lead Time: Verify current inventory status with your supplier, as availability may influence selection timing.
• Cost Considerations: Compare unit pricing and volume discounts from respective manufacturers or authorized distributors.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 390088-1 directly replace the 3M 929957-08 on existing PCBs?

A: Yes, provided the PCB layout accommodates the height difference (0.051" / 1.30mm lower profile). The matching grid configuration, pitch, contact finish, and electrical ratings ensure functional compatibility.

Q: Are there any electrical performance differences between these parts?

A: Both parts feature identical contact finish specifications (gold, 30.0µin) and matching pitch. The 3M part specifies 1A current rating; the TE part does not specify current rating in the provided data. Verify TE Connectivity specifications for current handling requirements in your application.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are RoHS compliant, carry UL94 V-0 flammability ratings, and have MSL 1 (Unlimited) moisture sensitivity levels.

Q: What is the significance of the housing material difference?

A: The 3M part uses glass-filled PBT while the TE part uses glass-filled polyester. Both materials meet UL94 V-0 requirements. Material selection may affect thermal properties and long-term environmental resistance; consult material datasheets for specific application requirements.

Q: Are these parts suitable for high-frequency applications?

A: The provided specifications do not include frequency ratings or impedance characteristics. Consult manufacturer datasheets for high-frequency performance data if required for your application.
