Substitute Part Grouping Explanation

Substitution of the 1-966443-0 is determined by strict equivalence across the following critical parameters:

Mechanical Compatibility Parameters:

  • Connector type classification (Header, Breakaway)
  • Contact type (Male Pin)
  • Position count (10 positions)
  • Row configuration (1 row)
  • Mating pitch (0.100" / 2.54mm)
  • Mounting method (Through Hole)
  • Termination method (Solder)
  • Contact dimensions (mating length, post length, overall length)
  • Insulation height and material (PBT)

Electrical Compatibility Parameters:

  • Contact finish specifications (Gold mating surface, Tin or Tin-Lead post)
  • Contact material (Copper Alloy)

Regulatory Compliance Parameters:

  • RoHS compliance status
  • Moisture Sensitivity Level (MSL 1)

The substitute part 6-966443-0 maintains identical mechanical and electrical specifications across all critical parameters. The primary distinction is product status: the 1-966443-0 is obsolete, while the 6-966443-0 is active. The 6-966443-0 is supplied in bulk packaging and features tin-plated posts rather than tin-lead plated posts, representing a modern RoHS-compliant alternative.

Engineering Selection Recommendations

The 6-966443-0 is the direct substitute for the obsolete 1-966443-0. Both parts share identical mechanical dimensions, contact specifications, and electrical characteristics within the AMPMODU Mod II series.

Product Status Consideration: The 1-966443-0 is classified as obsolete. The 6-966443-0 maintains active product status, ensuring ongoing availability and manufacturer support.

Compliance Status: Both parts meet RoHS compliance requirements. The 1-966443-0 carries ROHS3 compliance designation, while the 6-966443-0 carries RoHS compliance designation. Both are suitable for applications requiring lead-free solder compatibility.

Contact Finish Distinction: The primary technical difference is the post contact finish. The 1-966443-0 features tin-lead plating, while the 6-966443-0 features tin plating. Both finishes are compatible with standard solder processes and provide equivalent electrical performance for through-hole solder termination applications.

Packaging: The 6-966443-0 is supplied in bulk packaging, compared to the original part's unspecified packaging. This distinction affects inventory management and procurement logistics but does not impact functional compatibility.

For new designs and ongoing production requiring this connector type, the 6-966443-0 is the appropriate selection due to its active status and modern RoHS compliance profile.

Frequently Asked Questions (FAQ)

Q: Can the 6-966443-0 be used as a direct replacement for the 1-966443-0 in existing designs?

A: Yes. The 6-966443-0 is mechanically and electrically equivalent to the 1-966443-0. All critical dimensions, contact specifications, and electrical characteristics are identical. The connector will function identically in board-to-board or cable applications requiring a 10-position, 0.100" pitch header with through-hole solder termination.

Q: What is the significance of the different contact finish specifications (tin-lead versus tin)?

A: Both tin-lead and tin post finishes are compatible with standard solder reflow and wave soldering processes. The tin finish on the 6-966443-0 represents a modern, lead-free alternative that aligns with current RoHS compliance requirements. Both finishes provide equivalent electrical conductivity and solder joint reliability for this connector application.

Q: Are there any compatibility issues with PCB footprints designed for the 1-966443-0?

A: No. The 6-966443-0 maintains identical through-hole post dimensions (0.126" length) and overall contact length (0.465"). PCB footprints designed for the 1-966443-0 will accommodate the 6-966443-0 without modification.

Q: What is the difference between ROHS3 and RoHS compliance designations?

A: Both designations indicate compliance with lead-free and restricted substance requirements. ROHS3 represents the third iteration of the RoHS directive with updated restricted substance lists. Both the 1-966443-0 and 6-966443-0 meet current RoHS compliance standards for lead-free solder applications.

Q: Does the bulk packaging of the 6-966443-0 affect its electrical or mechanical performance?

A: No. Packaging designation refers only to the quantity and presentation format of the parts during distribution and storage. It does not affect the connector's electrical characteristics, mechanical dimensions, or functional performance in the application.

Q: Are both parts suitable for high-reliability applications?

A: Both parts carry Moisture Sensitivity Level 1 (Unlimited), indicating they do not require special moisture control during storage or handling. The gold-plated mating contacts and copper alloy base material provide reliable electrical performance for standard industrial and commercial applications.

Q: What is the mating pitch, and why is it critical for substitution?

A: The mating pitch is 0.100" (2.54mm), representing the center-to-center distance between adjacent contact positions. This specification is critical for substitution because it determines compatibility with mating connectors, cable assemblies, and PCB footprints. Both the 1-966443-0 and 6-966443-0 share identical 0.100" pitch specifications.
