TE Connectivity 7-146273-6 Rectangular Connector Header Equivalent & Substitute Parts

Part Overview

The TE Connectivity 7-146273-6 is a vertical rectangular connector header manufactured under the AMPMODU Mod II series. This through-hole mounted connector features 52 positions arranged in 2 rows with 0.100" (2.54mm) pitch spacing. The connector is designed for board-to-board or cable applications with male pin contacts and push-pull fastening.

The 7-146273-6 carries an obsolete product status. Identification of equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support ongoing production and maintenance requirements for systems utilizing this connector type.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for rectangular connector headers is determined by strict equivalence across critical mechanical and electrical parameters. The following parameters establish the substitution basis:

Critical Matching Parameters:

• Connector type classification (Header, Breakaway)
• Position count (52 positions)
• Row configuration (2 rows)
• Mating pitch (0.100" / 2.54mm)
• Row spacing (0.100" / 2.54mm)
• Contact type (Male Pin)
• Mounting method (Through Hole)
• Fastening mechanism (Push-Pull)
• Current rating (3A)
• Operating temperature range (-65°C ~ 105°C)
• Insulation material (Liquid Crystal Polymer)
• Contact material (Copper Alloy)
• Contact finish specifications (Gold mating, Tin post)
• Flammability rating (UL94 V-0)
• RoHS compliance status

Substitute parts must maintain identical values across all critical parameters. Variations in termination method (kinked pin versus standard solder) represent acceptable substitution differences when all other parameters remain equivalent, as termination method does not affect mating compatibility or electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 7-146261-6 is the manufacturer-recommended substitute for the obsolete 7-146273-6. Both connectors are manufactured by TE Connectivity within the AMPMODU Mod II series and maintain complete electrical and mechanical equivalence across all critical parameters.

The 7-146261-6 carries active product status, ensuring ongoing availability and manufacturing support. This part maintains identical specifications for connector geometry, contact configuration, pitch spacing, current rating, and operating temperature range. The termination method differs only in that the 7-146261-6 uses standard solder termination without the kinked pin feature present in the 7-146273-6; this variation does not affect mating compatibility or electrical performance.

Both parts are RoHS compliant and carry UL94 V-0 flammability certification. The 7-146261-6 is suitable for direct substitution in applications currently utilizing the 7-146273-6, with no design modifications required to PCB layouts or mating connector specifications.

Frequently Asked Questions (FAQ)

Q: Can the 7-146261-6 be used as a direct replacement for the 7-146273-6 in existing designs?

A: Yes. The 7-146261-6 is electrically and mechanically equivalent to the 7-146273-6 across all critical parameters including position count, pitch spacing, contact configuration, current rating, and operating temperature range. No design modifications are required.

Q: What is the difference between the kinked pin termination of the 7-146273-6 and the standard solder termination of the 7-146261-6?

A: The termination method affects only the manufacturing and assembly process. Both termination types provide equivalent electrical connection and mechanical retention when soldered to PCB pads. The kinked pin design provides additional mechanical support during assembly; standard solder termination relies on solder joint strength alone. Both methods are suitable for the specified current rating and operating conditions.

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

A: No. Both the 7-146273-6 and 7-146261-6 are RoHS compliant and carry UL94 V-0 flammability certification. Both maintain identical moisture sensitivity levels and contact finish specifications.

Q: Why is the 7-146273-6 listed as obsolete?

A: The 7-146273-6 has been superseded by the 7-146261-6 within the manufacturer's product line. The 7-146261-6 provides equivalent functionality with active product status and ongoing manufacturing support.

Q: What are the critical parameters that determine substitution eligibility for this connector type?

A: Substitution eligibility is determined by equivalence in connector type, position count, row configuration, mating pitch, row spacing, contact type, mounting method, fastening mechanism, current rating, operating temperature range, insulation material, contact material, contact finish specifications, and flammability rating. All these parameters must match between the original and substitute part.

Q: Is the 7-146261-6 available in the same packaging as the 7-146273-6?

A: Both parts are manufactured by TE Connectivity and are part of the same AMPMODU Mod II series. Standard packaging for both parts is consistent with TE Connectivity's connector header product line specifications.

Q: Can the 7-146261-6 handle the same current and voltage specifications as the 7-146273-6?

A: Yes. The 7-146261-6 maintains the same 3A current rating and operating temperature range of -65°C ~ 105°C as the 7-146273-6. Both parts are rated for identical electrical performance in their respective applications.
