Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3M 929953-30 is determined by the following critical parameters:

• Position Count & Grid Configuration: Must be 2 (1 x 2) positions
• Pitch Spacing: Must be 0.100" (2.54mm) to ensure mechanical compatibility with standard 0.100" header pins
• Connector Type: Must be Open Top shunt connector with Female Socket gender
• Contact Finish: Must be Gold to maintain electrical performance and corrosion resistance
• Flammability Rating: Must meet UL94 V-0 standard
• Current Rating: Must support minimum 1A current capacity
• RoHS Compliance: Must be RoHS compliant for regulatory alignment

The TE Connectivity AMP Connectors part number 382811-2 meets all critical substitution criteria within these parameters.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity AMP Connectors 382811-2 is a qualified substitute for the 3M 929953-30 based on the following engineering criteria:

Electrical Compatibility: Both parts feature gold-plated contacts, matching pitch spacing (0.100"), and identical position configuration (2 x 1 x 2). The substitute part maintains electrical performance requirements for standard shunt connector applications.

Mechanical Compatibility: The 0.100" pitch ensures direct mechanical interchangeability with standard 0.100" header pin spacing. Height difference of 0.010" (0.25mm) is within typical PCB assembly tolerances and does not affect functional performance.

Regulatory Compliance: Both parts are RoHS compliant and carry UL94 V-0 flammability ratings, meeting current regulatory requirements for electronic component applications.

Product Status: Both parts maintain Active product status, ensuring continued availability and manufacturing support.

Material Consideration: The substitute uses polyester glass-filled housing versus polybutylene terephthalate in the original. Both materials meet UL94 V-0 requirements and are suitable for standard operating environments.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 382811-2 be used as a direct replacement for the 3M 929953-30?

A: Yes. Both parts share identical electrical and mechanical specifications for the critical substitution parameters: 2-position configuration, 0.100" pitch, open top design, female socket gender, and gold contact finish. The parts are mechanically and electrically interchangeable in standard shunt connector applications.

Q: What is the significance of the 0.010" height difference between the two parts?

A: The height difference (3M: 0.240", TE: 0.250") is within standard PCB assembly tolerances and does not affect functional performance or mechanical fit on 0.100" pitch headers. Both heights accommodate standard connector pin engagement depths.

Q: Does the difference in contact finish thickness affect performance?

A: The substitute part features 15.0µin (0.38µm) gold plating versus 30.0µin (0.76µm) on the original. Both thicknesses provide adequate corrosion resistance and electrical conductivity for standard shunt connector applications. The thinner plating on the substitute remains within industry-standard specifications for this connector class.

Q: Are there any material compatibility concerns with the polyester housing versus polybutylene terephthalate?

A: No. Both materials are glass-filled thermoplastics meeting UL94 V-0 flammability requirements. Polyester and polybutylene terephthalate exhibit similar mechanical and thermal properties suitable for standard operating environments. Material selection does not affect electrical performance or mechanical compatibility.

Q: What packaging differences exist between these parts?

A: The 3M 929953-30 is supplied in Strip packaging (20 pieces per strip), while the TE Connectivity 382811-2 is supplied in Bulk packaging. Packaging format does not affect component performance or compatibility; selection depends on procurement and assembly requirements.

Q: Are both parts currently available?

A: Yes. Both parts maintain Active product status. The 3M 929953-30 has 1114 pieces in stock, and the TE Connectivity 382811-2 has 3100 pieces in stock, indicating current manufacturing and distribution support.
