Key Parameters

Substitute Part Grouping Explanation

Substitution of the 6-146273-9 is determined by strict equivalence across the following critical parameters:

Mechanical Compatibility:

• Connector type (Header, Breakaway)
• Number of positions (38)
• Number of rows (2)
• Pitch spacing (0.100" / 2.54mm mating and row spacing)
• Mounting type (Through Hole)
• Contact shape (Square)
• Insulation material (Liquid Crystal Polymer)

Electrical Compatibility:

• Contact type (Male Pin)
• Current rating (3A)
• Operating temperature range (-65°C ~ 105°C)
• Contact finish specifications (Gold mating surface, Tin post)
• Material flammability rating (UL94 V-0)

Environmental & Regulatory Compliance:

• RoHS compliance status
• Moisture sensitivity level (MSL 1)

The substitute part 6-146261-9 maintains equivalence across all critical parameters with one functional difference: termination method. The main part features kinked pin and solder termination, while the substitute features solder termination only. This difference does not affect mechanical or electrical compatibility in applications where solder termination is acceptable.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 6-146261-9 is the direct substitute for the obsolete 6-146273-9. Both connectors are manufactured by TE Connectivity within the AMPMODU Mod II series and maintain identical mechanical and electrical specifications across all critical parameters.

The 6-146261-9 holds active product status, ensuring continued availability and supply chain support. Both parts carry RoHS compliance certification and identical regulatory classifications (ECCN EAR99, HTSUS 8536.69.4040), confirming regulatory equivalence.

The primary functional difference is termination method. The 6-146273-9 features kinked pin and solder termination, while the 6-146261-9 features solder termination only. This distinction does not affect mechanical fit, electrical performance, or contact integrity in applications where solder termination is the intended assembly method.

Selection of the 6-146261-9 is appropriate for new designs, production restocking, and legacy system maintenance where the obsolete 6-146273-9 is no longer available through standard distribution channels.

Frequently Asked Questions (FAQ)

Q: Are the 6-146273-9 and 6-146261-9 mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications including 38 positions, 2-row configuration, 0.100" (2.54mm) pitch spacing, through-hole mounting, and contact dimensions. Physical fit and board layout compatibility are equivalent.

Q: What is the difference between kinked pin and solder termination?

A: The 6-146273-9 features kinked pin termination in addition to solder termination, providing mechanical retention during assembly. The 6-146261-9 features solder termination only. Both methods provide equivalent electrical connection when properly soldered. Selection depends on assembly process requirements and mechanical retention preferences.

Q: Can the 6-146261-9 be used in applications originally designed for the 6-146273-9?

A: Yes, provided the application does not require kinked pin mechanical retention during assembly. Electrical performance, current capacity (3A), operating temperature range (-65°C ~ 105°C), and contact specifications are identical. Verify assembly process compatibility with solder-only termination.

Q: Are both parts RoHS compliant?

A: Yes. Both the 6-146273-9 and 6-146261-9 carry RoHS compliance certification and are suitable for applications requiring RoHS-compliant components.

Q: What is the moisture sensitivity level for these connectors?

A: Both connectors carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity restrictions during storage or handling.

Q: Why is the 6-146273-9 listed as obsolete?

A: The 6-146273-9 has been discontinued by TE Connectivity. The 6-146261-9 serves as the active replacement within the AMPMODU Mod II series, maintaining full specification equivalence while ensuring ongoing availability and supply chain support.

Q: Are there any electrical performance differences between these parts?

A: No. Both connectors maintain identical electrical specifications: 3A current rating, gold-plated mating contacts (30.0µin thickness), tin-plated posts (100.0µin thickness), copper alloy contact material, and UL94 V-0 flammability rating.
