TE Connectivity AMP Connectors 6-146252-1 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 6-146252-1 is an active rectangular connector header designed for through-hole mounting applications. This 22-position, 2-row connector operates within the AMPMODU Mod II series and provides board-to-board or cable interconnection with push-pull fastening. The connector is manufactured from liquid crystal polymer insulation with gold-plated mating contacts and tin-plated posts, rated for 3A current at operating temperatures between -65°C and 105°C. Identification of equivalent substitute parts becomes necessary when managing component availability, supply chain optimization, or design flexibility across manufacturing batches while maintaining electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

TE Connectivity 6-146252-1 is the primary specification component with active product status and RoHS compliance. This connector is suitable for applications requiring the extended lower operating temperature limit of -65°C and liquid crystal polymer insulation properties.

Würth Elektronik 61302221121 qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. This connector maintains active product status with ROHS3 compliance, which is equivalent to RoHS Compliant designation. The operating temperature range of -40°C to 105°C is acceptable for applications not requiring sub-zero operation below -40°C. The polyamide insulation material provides equivalent performance characteristics for standard board-to-board and cable interconnection applications. Contact length variations are within acceptable mechanical envelope tolerances for standard through-hole PCB mounting.

Selection between these two connectors depends on application-specific temperature requirements and insulation material preferences. Both connectors carry UL94 V-0 flammability certification and maintain 3A current rating with identical pitch, position count, and contact configuration.

Frequently Asked Questions (FAQ)

Q: Can the Würth Elektronik 61302221121 be used as a direct replacement for the TE Connectivity 6-146252-1 in all applications?

A: The Würth Elektronik 61302221121 is a direct substitute for applications operating within the -40°C to 105°C temperature range. Applications requiring operation below -40°C must use the TE Connectivity 6-146252-1 due to its extended lower temperature limit of -65°C.

Q: Are there differences in contact length between these two connectors?

A: Yes. The TE Connectivity 6-146252-1 has a mating contact length of 0.318" (8.08mm), while the Würth Elektronik 61302221121 has a mating contact length of 0.236" (6.00mm). These variations are within acceptable mechanical envelope tolerances for standard through-hole PCB mounting and do not affect electrical compatibility.

Q: What is the difference between RoHS Compliant and ROHS3 Compliant?

A: ROHS3 Compliant refers to compliance with the Restriction of Hazardous Substances Directive 2011/65/EU (recast), which is the current regulatory standard. RoHS Compliant typically refers to the original 2002/95/EC directive. Both designations indicate equivalent restriction of hazardous substances and are acceptable for substitution purposes.

Q: Do both connectors have the same insulation material?

A: No. The TE Connectivity 6-146252-1 uses Liquid Crystal Polymer (LCP) insulation, while the Würth Elektronik 61302221121 uses Polyamide (PA6T), Nylon 6T insulation. Both materials provide UL94 V-0 flammability rating and are suitable for board-to-board and cable interconnection applications.

Q: Are the current ratings identical?

A: Yes. Both connectors are rated for 3A continuous current and are suitable for equivalent power distribution applications.

Q: What is the pitch specification for these connectors?

A: Both connectors feature a 0.100" (2.54mm) pitch for mating contacts and 0.100" (2.54mm) row spacing, ensuring mechanical and electrical compatibility with standard 2.54mm pitch connector systems.

Q: Can these connectors be used interchangeably on the same PCB?

A: Yes, both connectors share identical mounting specifications (through-hole, 22 positions, 2 rows, 2.54mm pitch) and can be used interchangeably on PCBs designed for standard 2.54mm pitch headers, provided application temperature requirements are met.
