TE Connectivity 350429-2 Rectangular Connector Header Equivalent & Substitute Parts

Part Overview

The TE Connectivity 350429-2 is a vertical rectangular connector header manufactured under the Universal MATE-N-LOK series. This through-hole mounted connector features a 3-position configuration with 0.250" (6.35mm) pitch spacing and is designed for board-to-cable/wire applications. The connector employs shrouded 4-wall construction with solder termination and locking ramp fastening. The part is currently active in production status. Substitute parts are identified when equivalent electrical and mechanical parameters are required but alternative packaging, compliance certifications, or inventory availability necessitate component selection from the qualified substitute list.

Key Parameters

Substitute Part Grouping Explanation

Substitution of rectangular connector headers is determined by equivalence across the following critical parameters: connector type, contact type, number of positions, pitch spacing, mounting method, shrouding configuration, termination type, fastening mechanism, insulation material, and contact finish specifications. The TE Connectivity 350429-2 and its identified substitute 350429-4 share identical electrical and mechanical characteristics across all these parameters. Both connectors are part of the Universal MATE-N-LOK series and maintain the same 3-position, 0.250" pitch configuration with through-hole solder termination and 4-wall shrouded design.

The primary distinction between these parts lies in packaging format and compliance certification status. The 350429-2 is supplied in standard packaging with RoHS non-compliant status, while the 350429-4 is supplied in bulk packaging with ROHS3 compliance. Both parts are active products with identical functional specifications, making them interchangeable for applications where the packaging format and compliance requirements align with system needs.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 350429-2 and 350429-4 are functionally equivalent rectangular connector headers with identical electrical and mechanical specifications. Selection between these parts is determined by compliance requirements and packaging format needs.

350429-2 is appropriate for applications where RoHS non-compliant components are acceptable and standard packaging is preferred. This part maintains active product status and is suitable for general-purpose board-to-cable/wire connection applications.

350429-4 is appropriate for applications requiring ROHS3 compliance certification. This part is supplied in bulk packaging and is suitable for high-volume production environments or applications with regulatory requirements mandating RoHS3 compliance. The bulk packaging format provides cost efficiency for large-scale deployments.

Both parts are active products manufactured by TE Connectivity and share identical connector architecture, contact configuration, and termination specifications. Selection should be based on compliance certification requirements and packaging format compatibility with procurement and assembly processes.

Frequently Asked Questions (FAQ)

Q: Are the 350429-2 and 350429-4 mechanically interchangeable?
