Substitute Part Grouping Explanation

Substitution between TE Connectivity 643230-2 and 3-643230-0 is based on strict equivalence of the following critical parameters:

Functional Equivalence Parameters:

• Connector type, contact type, and style (Header, Female Socket, Board to Cable/Wire)
• Number of positions and pitch (4 positions, 0.250" mating pitch)
• Mounting configuration (Through Hole, Right Angle)
• Termination method (Solder)
• Insulation material and flammability rating (Polyamide/Nylon, UL94 V-0)
• Contact material and mating finish (Phosphor Bronze, Gold plated)

Differentiating Parameters:

• Packaging format (standard vs. bulk)
• Contact finish on posts (Tin-Lead vs. Tin)
• RoHS compliance status
• REACH compliance documentation

Both parts share the same base product number (643230) and series designation, confirming their functional interchangeability within the MATE-N-LOK connector family.

Parameter Comparison

Engineering Selection Recommendations

643230-2 Selection Criteria:

• Applications requiring tin-lead post finish for legacy solder processes
• Non-RoHS compliant system designs
• Standard packaging requirements
• REACH-affected supply chain documentation

3-643230-0 Selection Criteria:

• RoHS-compliant applications and regulatory environments
• Tin post finish compatibility with lead-free solder processes
• Bulk packaging for high-volume production runs
• Applications where RoHS compliance is mandatory

Both parts maintain identical mechanical and electrical interface specifications, ensuring direct substitution capability within the MATE-N-LOK connector ecosystem. Selection between these parts is determined by compliance requirements, post-finish specifications, and packaging format rather than functional performance differences.

Frequently Asked Questions (FAQ)

Q: Are 643230-2 and 3-643230-0 mechanically interchangeable?

A: Yes. Both connectors share identical mating pitch (0.250"), mounting configuration (through-hole right-angle), insulation dimensions (0.360" height), and contact geometry (circular, phosphor bronze). They are mechanically interchangeable in all board-level applications.

Q: What is the difference in post finish between these parts?

A: The 643230-2 features tin-lead plated posts, while the 3-643230-0 features tin-plated posts. This distinction affects solder compatibility and thermal cycling performance in different manufacturing processes.

Q: Can I use 3-643230-0 in a design originally specified for 643230-2?

A: Substitution is possible when RoHS compliance is required or when lead-free solder processes are employed. The tin post finish of 3-643230-0 is compatible with lead-free solder systems, whereas the tin-lead finish of 643230-2 is optimized for traditional solder processes.

Q: What does the packaging difference mean?

A: 643230-2 is supplied in standard packaging, while 3-643230-0 is supplied in bulk packaging. This affects order quantities, handling, and storage but does not impact connector performance or compatibility.

Q: Are both parts currently in production?

A: Yes. Both parts maintain active product status with TE Connectivity and have current inventory availability (1102 and 1106 pieces respectively).

Q: Which part should I specify for new designs?

A: Selection depends on regulatory requirements and manufacturing process specifications. For RoHS-compliant designs or lead-free solder environments, specify 3-643230-0. For legacy systems or tin-lead solder processes, 643230-2 remains appropriate.

Q: Do these connectors have voltage or current ratings?

A: Voltage and current ratings are not specified in the provided technical documentation for either part. Consult the complete datasheet for electrical performance specifications.
