Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 6-146281-0 serves as the direct functional equivalent to the obsolete 104344-8. Selection of the substitute part is based on the following engineering criteria:

Product Status Alignment: The 104344-8 is classified as obsolete, while the 6-146281-0 maintains active product status. This transition ensures continued availability and manufacturing support for new designs and production continuity.

Electrical & Mechanical Equivalence: Both parts maintain identical specifications across all critical electrical parameters (10-position, 0.100" pitch, 3A current rating, -65°C to 105°C operating range) and mechanical dimensions (contact lengths, insulation height, overall form factor). This equivalence ensures direct interchangeability in existing circuit board layouts and connector mating interfaces.

Material & Environmental Compliance: Both connectors meet UL94 V-0 flammability requirements and maintain MSL 1 (Unlimited) moisture sensitivity ratings. The substitute part features Liquid Crystal Polymer (LCP) insulation material in place of thermoplastic, providing enhanced thermal and chemical resistance while maintaining mechanical compatibility.

Regulatory Compliance Enhancement: The 6-146281-0 achieves RoHS compliance status, whereas the 104344-8 is RoHS non-compliant. This compliance improvement aligns with current regulatory requirements for electronic component procurement and end-product certification.

Contact Finish Compatibility: The substitute part utilizes tin contact finish on the post termination, compared to tin-lead on the main part. Both finishes are compatible with standard solder reflow processes and provide equivalent electrical performance.

Frequently Asked Questions (FAQ)

Q: Can the 6-146281-0 be used as a direct replacement for the 104344-8 in existing designs?

A: Yes. The 6-146281-0 maintains identical electrical and mechanical specifications across all critical parameters, including connector type, contact configuration, pitch spacing, current rating, and operating temperature range. Direct substitution is supported without circuit board redesign or connector interface modifications.

Q: What is the difference in insulation material between the two parts?

A: The 104344-8 uses thermoplastic insulation material, while the 6-146281-0 uses Liquid Crystal Polymer (LCP). LCP provides superior thermal stability and chemical resistance while maintaining mechanical compatibility and identical insulation height specifications.

Q: Are there differences in contact finish specifications?

A: The mating contact finish (gold) is identical on both parts. The post contact finish differs: the 104344-8 uses tin-lead, while the 6-146281-0 uses tin. Both finishes are compatible with standard solder reflow processes and provide equivalent electrical performance.

Q: Does the substitute part meet RoHS compliance requirements?

A: Yes. The 6-146281-0 is RoHS compliant, whereas the 104344-8 is RoHS non-compliant. This compliance improvement is beneficial for applications subject to RoHS regulatory requirements.

Q: Are the packaging formats different between the two parts?

A: The 104344-8 packaging format is not specified in the available data. The 6-146281-0 is supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: What is the current availability status of each part?

A: The 104344-8 is classified as obsolete with 927 pieces in stock. The 6-146281-0 is an active product with 4,665 pieces in stock, ensuring continued availability for production requirements.

Q: Are both parts from the same manufacturer and series?

A: Yes. Both connectors are manufactured by TE Connectivity AMP Connectors and are part of the AMPMODU Mod II series, ensuring design consistency and interchangeability.

Q: What are the moisture sensitivity level ratings for both parts?

A: Both the 104344-8 and 6-146281-0 maintain MSL 1 (Unlimited) moisture sensitivity ratings, indicating no special moisture control requirements during storage, handling, or assembly.
