Substitute Part Grouping Explanation

Substitution of the obsolete 146261-6 with the active equivalent 5-146261-6 is based on strict electrical and mechanical parameter matching within the AMPMODU Mod II series. Both parts maintain identical specifications across all critical parameters that determine functional compatibility:

Key Substitution Parameters:

• Connector type, contact type, and pin configuration (12-position, 2-row header)
• Mating pitch and row spacing (0.100" / 2.54mm)
• Mounting method and termination type (through-hole solder)
• Contact geometry and mating contact length (0.230" / 5.84mm)
• Operating temperature range (-65°C ~ 105°C)
• Current rating (3A)
• Insulation material and flammability rating (LCP, UL94 V-0)
• Compliance certifications (RoHS Compliant, REACH Affected, EAR99)

The primary distinction between these parts is product status (obsolete versus active) and contact finish on the post (Tin-Lead versus Tin). The substitute part 5-146261-6 is the direct active replacement within the same connector series.

Parameter Comparison

Engineering Selection Recommendations

The substitute part 5-146261-6 is the direct active equivalent for the obsolete 146261-6. Selection of the substitute is based on the following engineering criteria:

Product Status: The main part 146261-6 is classified as obsolete. The substitute 5-146261-6 maintains active product status, ensuring availability for current and future production requirements.

Electrical and Mechanical Compatibility: All critical electrical and mechanical parameters are identical between the main part and substitute, including connector type, pin configuration, pitch spacing, contact geometry, current rating, and operating temperature range.

Compliance and Certifications: Both parts maintain identical compliance status across RoHS, REACH, and export control classifications (EAR99). Both parts carry UL94 V-0 flammability rating and MSL 1 moisture sensitivity level.

Contact Finish Difference: The substitute part uses Tin finish on the post, whereas the main part uses Tin-Lead finish. This change reflects industry-wide transition toward lead-free manufacturing practices while maintaining equivalent electrical and mechanical performance.

Packaging Consideration: The substitute part is supplied in Bulk packaging, whereas the main part packaging is not specified. This distinction does not affect functional compatibility but may influence procurement and inventory management processes.

Frequently Asked Questions (FAQ)

Q: Can the 5-146261-6 be used as a direct replacement for the 146261-6 in existing designs?

A: Yes. The 5-146261-6 is functionally equivalent to the 146261-6 across all critical electrical and mechanical parameters. Both parts are 12-position, 2-row headers with 2.54mm pitch, identical contact geometry, and matching operating specifications. The substitute is suitable for direct replacement in board-to-board and cable connection applications.

Q: What is the difference between the Tin-Lead finish on the 146261-6 and the Tin finish on the 5-146261-6?

A: The contact finish on the post differs between these parts. The 146261-6 uses Tin-Lead, while the 5-146261-6 uses Tin. Both finishes provide equivalent electrical performance and solder joint reliability. The change to Tin reflects industry transition toward lead-free manufacturing. Both parts maintain identical gold plating on the mating contact surface.

Q: Are there any compatibility issues with PCB footprints or mating connectors?

A: No. Both parts maintain identical physical dimensions, pitch spacing (0.100" / 2.54mm), contact geometry, and mounting specifications. PCB footprints designed for the 146261-6 are directly compatible with the 5-146261-6 without modification.

Q: What is the significance of the product status difference between these parts?

A: The 146261-6 is classified as obsolete, indicating it is no longer in active production and may have limited availability. The 5-146261-6 is classified as active, ensuring continued manufacturing and supply chain availability. For new designs and ongoing production, the active substitute is the appropriate selection.

Q: Do both parts meet the same compliance and certification requirements?

A: Yes. Both the 146261-6 and 5-146261-6 are RoHS Compliant, REACH Affected, and classified under ECCN EAR99. Both carry UL94 V-0 flammability rating and MSL 1 moisture sensitivity level. Compliance certifications are identical across both parts.

Q: What is the current rating for these connectors?

A: Both parts are rated for 3A continuous current. This rating applies to each individual contact within the 12-position header configuration.

Q: Are these connectors suitable for high-temperature applications?

A: Yes. Both parts maintain an operating temperature range of -65°C to 105°C, suitable for industrial and commercial applications requiring extended temperature performance. The Liquid Crystal Polymer (LCP) insulation material supports this temperature range.
