Key Parameters

Substitute Part Grouping Explanation

Substitution of the 5-146273-9 is determined by strict equivalence across the following critical parameters:

Mechanical Compatibility:

• Connector type (Header, Breakaway)
• Contact type (Male Pin)
• Position count (18 positions)
• Row configuration (2 rows)
• Pitch spacing (0.100" mating pitch, 0.100" row spacing)
• Mounting method (Through Hole)

Electrical & Environmental Compatibility:

• Contact finish specifications (Gold mating surface, Tin post finish)
• Insulation material (Liquid Crystal Polymer)
• Operating temperature range (-65°C ~ 105°C)
• Current rating (3A)
• Flammability rating (UL94 V-0)
• RoHS compliance status

Termination Consideration: The primary distinction between the main part and substitute parts lies in the termination method. The 5-146273-9 specifies kinked pin solder termination, while substitute parts may employ alternative solder termination configurations. This difference does not affect mechanical or electrical compatibility when both termination types are solder-based and compatible with standard PCB assembly processes.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 5-146261-9 serves as the direct substitute for the obsolete 5-146273-9. Both connectors are manufactured by TE Connectivity within the AMPMODU Mod II series and maintain identical mechanical, electrical, and environmental specifications across all critical parameters.

Compliance & Certification Alignment: Both parts carry RoHS Compliant status and UL94 V-0 flammability rating, ensuring regulatory equivalence for applications subject to environmental and safety standards. The substitute part maintains the same operating temperature range (-65°C ~ 105°C) and current rating (3A), confirming suitability for equivalent thermal and power delivery requirements.

Product Status Advantage: The 5-146261-9 carries Active product status, ensuring ongoing availability, supply chain support, and manufacturer technical documentation. Selection of the active substitute part eliminates obsolescence risk associated with the 5-146273-9.

Termination Compatibility: The termination difference (kinked pin solder versus standard solder) represents a compatible variation within solder-based assembly processes. Both termination configurations are compatible with standard PCB through-hole soldering methods and do not introduce mechanical or electrical incompatibility.

Frequently Asked Questions (FAQ)

Q: Are the 5-146273-9 and 5-146261-9 mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications including 18-position, 2-row configuration with 0.100" (2.54mm) pitch spacing, through-hole mounting, and contact dimensions. PCB footprints designed for either part are directly compatible.

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

A: Kinked pin termination features a bent contact post designed to enhance mechanical retention during PCB assembly. Standard solder termination uses a straight contact post. Both configurations are solder-compatible and produce equivalent electrical connections. The termination difference does not affect mating performance or electrical characteristics.

Q: Can I use the 5-146261-9 as a direct replacement in existing designs?

A: Yes. The 5-146261-9 is electrically and mechanically equivalent to the 5-146273-9 across all specified parameters. No design modifications are required for substitution.

Q: Why is the 5-146273-9 marked as obsolete?

A: Product obsolescence reflects manufacturer discontinuation decisions. The 5-146261-9 represents the active equivalent within the same product family, ensuring continued availability and support.

Q: Are there any environmental or compliance differences between these parts?

A: No. Both parts maintain identical RoHS Compliant status, UL94 V-0 flammability rating, and operating temperature specifications (-65°C ~ 105°C). Regulatory and environmental compliance requirements are equivalent.

Q: What is the current rating for both connectors?

A: Both the 5-146273-9 and 5-146261-9 are rated for 3A continuous current per contact, ensuring equivalent power delivery capability.

Q: Are the contact finishes identical?

A: Yes. Both connectors feature gold-plated mating surfaces (30.0µin thickness) and tin-plated posts (100.0µin thickness), providing identical electrical contact properties and corrosion resistance.

Q: Is the insulation material the same for both parts?

A: Yes. Both connectors use Liquid Crystal Polymer (LCP) insulation material with UL94 V-0 flammability rating and black color, ensuring identical mechanical and thermal properties.
