Substitute Part Grouping Explanation

Substitution of the obsolete 146281-6 is based on strict electrical and mechanical parameter equivalence within the AMPMODU Mod II series. The substitute part 5-146281-6 maintains identical specifications across all critical dimensions and functional characteristics:

Key Parameters Determining Substitution:

• Connector type, contact type, and gender (Header, Breakaway; Male Pin)
• Number of positions and pitch (6 positions at 0.100" / 2.54mm)
• Mounting method and termination (Through Hole; Solder)
• Contact dimensions and materials (Copper Alloy with Gold mating finish)
• Insulation material and flammability rating (Liquid Crystal Polymer; UL94 V-0)
• Operating temperature range (-65°C ~ 105°C)
• Current rating (3A)
• Moisture sensitivity level (MSL 1)

The substitute part differs only in product status (Active versus Obsolete) and packaging configuration (Bulk), with minor variations in post-contact finish specification and regulatory compliance documentation.

Parameter Comparison

Engineering Selection Recommendations

The substitute part 5-146281-6 is the direct active equivalent for the obsolete 146281-6. Both parts are manufactured by TE Connectivity within the AMPMODU Mod II series and maintain identical electrical and mechanical specifications.

Selection Basis:

The 5-146281-6 is recommended for new designs and production applications due to its Active product status and current availability. The part maintains full compliance with RoHS3 standards and carries the same UL94 V-0 flammability rating and MSL 1 moisture sensitivity classification as the original part.

The primary distinction between the two parts is the post-contact finish specification: the original 146281-6 uses Tin-Lead plating, while the substitute 5-146281-6 uses Tin plating. This change reflects industry transition toward lead-free manufacturing practices and does not affect functional compatibility or performance within the specified operating parameters.

Both parts are suitable for applications requiring 3A current capacity across the -65°C to 105°C operating temperature range. The through-hole solder termination and push-pull fastening mechanism remain unchanged, ensuring direct mechanical and electrical interchangeability in existing PCB designs.

Frequently Asked Questions (FAQ)

Q: Can the 5-146281-6 be used as a direct replacement for the 146281-6 in existing designs?

A: Yes. The 5-146281-6 maintains identical electrical and mechanical specifications across all critical parameters including connector type, position count, pitch, mounting method, current rating, and operating temperature range. The parts are mechanically and electrically interchangeable.

Q: What is the difference between the Tin-Lead finish on the original part and the Tin finish on the substitute?

A: The original 146281-6 features Tin-Lead post-contact plating, while the 5-146281-6 uses Tin plating. Both finishes provide equivalent solderability and electrical performance. The Tin finish on the substitute reflects compliance with lead-free manufacturing standards (RoHS3) and does not impact functional compatibility.

Q: Are there any packaging differences between these parts?

A: The 146281-6 packaging specification is not provided in the available data. The 5-146281-6 is supplied in Bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: Do both parts meet the same regulatory and compliance standards?

A: Both parts carry UL94 V-0 flammability ratings and MSL 1 moisture sensitivity classifications. The 146281-6 is RoHS Compliant, while the 5-146281-6 is ROHS3 Compliant, representing an updated compliance standard. Both parts share identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications.

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

A: The 146281-6 is classified as Obsolete with 882 pieces reported in stock. The 5-146281-6 is Active with 8913 pieces in stock, providing superior long-term availability for ongoing production and field service requirements.

Q: Are the contact dimensions identical between the two parts?

A: Yes. Both parts feature identical contact dimensions: 0.230" (5.84mm) mating length, 0.120" (3.05mm) post length, and 0.440" (11.18mm) overall contact length. The insulation height of 0.090" (2.29mm) is also identical, ensuring direct mechanical compatibility.

Q: Can these parts be used interchangeably in new PCB designs?

A: Yes. The 5-146281-6 is the recommended choice for new designs due to its Active status and current availability. The identical specifications ensure that existing PCB layouts and mating connector designs require no modification.
