TE Connectivity 643228-2 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 643228-2 is a 3-position header connector from the Universal MATE-N-LOK series, designed for board-to-cable/wire applications. This rectangular connector features a 0.250" (6.35mm) pitch, right-angle through-hole mounting, and gold-plated mating contacts. The connector is classified as Active product status and is currently in stock with 743 pieces available.

Substitute parts are identified to provide alternative sourcing options when the primary part number is unavailable or when packaging requirements differ. The substitute maintains functional equivalence through matching electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

The substitute part 3-643228-0 is functionally equivalent to the main part 643228-2 based on the following critical parameters:

Matching Specifications:

• Connector type, contact type, and style (Header, Female Socket, Board to Cable/Wire)
• Number of positions and pitch (3 positions, 0.250" mating pitch)
• Mounting configuration (Through Hole, Right Angle)
• Termination method (Solder)
• Contact finish material and thickness at mating interface (Gold, 30.0µin)
• Insulation material and height (Polyamide/Nylon, 0.360")
• Contact geometry and material (Circular, Phosphor Bronze)
• Fastening type (Locking Ramp)
• Flammability rating (UL94 V-0)
• Series designation (Universal MATE-N-LOK)

The primary distinction between these parts is packaging format and post-contact finish specification, which do not affect functional compatibility in the application circuit.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (643228-2): The 643228-2 is the original specification part with Active product status. This part number is suitable for applications where the original design specification must be maintained exactly as documented.

Substitute Part Selection (3-643228-0): The 3-643228-0 is a direct functional equivalent with Active product status and RoHS Compliant certification. This part is suitable for applications requiring RoHS compliance or when bulk packaging is preferred. The post-contact finish differs (Tin versus Tin-Lead), which is functionally equivalent for solder termination applications. The substitute provides higher inventory availability (1702 pieces versus 743 pieces).

Both parts share identical mating interface specifications, mechanical dimensions, and electrical characteristics. Selection between these parts should be based on regulatory compliance requirements, packaging format needs, and inventory availability for the specific application.

Frequently Asked Questions (FAQ)

Q: Can 3-643228-0 be used as a direct replacement for 643228-2 in existing designs?

A: Yes. Both parts are functionally equivalent in all critical parameters including connector type, position count, pitch, mounting configuration, and mating contact specifications. The parts are mechanically and electrically interchangeable in board-to-cable/wire applications.

Q: What is the difference between the post-contact finishes (Tin-Lead versus Tin)?

A: The post-contact finish does not affect mating interface performance. Both finishes are suitable for solder termination. The Tin finish on 3-643228-0 reflects RoHS compliance, while the Tin-Lead finish on 643228-2 is non-compliant. Selection depends on regulatory requirements for the end application.

Q: Does the RoHS compliance difference affect compatibility?

A: RoHS compliance is a regulatory and supply chain consideration, not a functional compatibility issue. Both parts perform identically in the circuit. Selection should be based on whether the application or end-market requires RoHS-compliant components.

Q: What is the significance of the different packaging formats?

A: The 643228-2 uses standard packaging while 3-643228-0 uses bulk packaging. This affects order quantities and handling but does not impact the connector's electrical or mechanical performance. Bulk packaging typically offers cost advantages for high-volume production.

Q: Are there any operating temperature or current rating specifications provided?

A: Operating temperature and current rating specifications are not provided in the available technical data for either part. Refer to the complete TE Connectivity datasheet for the Universal MATE-N-LOK series for these parameters.

Q: Can these connectors be used interchangeably with other MATE-N-LOK series connectors?

A: Compatibility within the MATE-N-LOK series depends on matching the specific position count, pitch, and contact type. The 643228-2 and 3-643228-0 are both 3-position, 0.250" pitch connectors with female socket contacts. They are compatible with corresponding male connector plugs designed for this configuration within the Universal MATE-N-LOK series.
