TE Connectivity 146225-3 Rectangular Connector: Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 146225-3 is a vertical header connector with 3 positions at 2.54mm pitch, designed for through-hole board-to-board or cable applications. This connector features male pins with gold-plated mating contacts and tin-lead plated posts, operating across a temperature range of -65°C to 105°C with a 3A current rating at 30VAC.

The 146225-3 carries an obsolete product status, making identification of active equivalent components essential for ongoing design support, maintenance, and new production requirements. Substitute parts must maintain electrical and mechanical compatibility while offering active product availability and improved compliance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 146225-3 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

• Pitch spacing: 0.100" (2.54mm) — determines mating compatibility with existing receptacles and PCB layouts
• Contact type: Male pin configuration — ensures proper mating with standard female receptacles
• Number of positions: 3-position single-row configuration — maintains circuit connectivity requirements
• Operating temperature range: -65°C to 105°C — ensures thermal performance across application environments
• Current and voltage ratings: 3A at 30VAC — validates power handling capacity

Mechanical Compatibility Parameters:

• Mounting type: Through-hole solder termination — ensures PCB assembly compatibility
• Contact dimensions: Mating length 0.230" (5.84mm), post length 0.090" (2.29mm), overall length 0.410" (10.41mm) — guarantees physical fit and engagement depth
• Insulation height: 0.090" (2.29mm) — maintains board clearance and stacking compatibility
• Contact shape: Square — ensures proper contact alignment and retention
• Connector type: Header, breakaway — preserves functional form factor

Compliance and Availability Parameters:

• Series: AMPMODU Mod II — maintains design family consistency
• Contact finish: Gold mating surface — preserves electrical performance and corrosion resistance

The substitute part 5-146283-3 meets all critical electrical and mechanical parameters while offering active product status and improved material specifications.

Engineering Selection Recommendations

Primary Substitute: TE Connectivity 5-146283-3

The 5-146283-3 is the direct active equivalent for the obsolete 146225-3. This substitute maintains full electrical and mechanical compatibility across all critical parameters including pitch spacing, contact configuration, dimensions, and operating temperature range.

Material Enhancement: The substitute incorporates Liquid Crystal Polymer (LCP) insulation material in place of thermoplastic, providing improved dimensional stability and thermal performance characteristics. The post finish transitions from tin-lead to tin, which is compatible with modern RoHS-compliant soldering processes and eliminates lead content.

Compliance Status: The 5-146283-3 carries active product status, ensuring long-term availability and supply chain continuity. Both parts share identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications, maintaining regulatory consistency.

Availability: The substitute part maintains higher inventory levels (1130 pcs vs. 884 pcs), supporting both immediate requirements and future production needs.

Frequently Asked Questions (FAQ)

Q: Can the 5-146283-3 directly replace the 146225-3 in existing designs?

A: Yes. The 5-146283-3 maintains identical electrical and mechanical specifications across all critical parameters including pitch, contact configuration, dimensions, and operating temperature range. Direct substitution is supported without design modification.

Q: What is the difference between the insulation materials used in these connectors?

A: The 146225-3 uses thermoplastic insulation, while the 5-146283-3 uses Liquid Crystal Polymer (LCP). LCP provides superior dimensional stability and thermal performance. Both materials are compatible with the specified operating temperature range of -65°C to 105°C.

Q: Does the change from tin-lead to tin post finish affect soldering compatibility?

A: No. Tin post finish is compatible with standard solder reflow processes and is the current industry standard. Tin-lead finish is no longer preferred due to RoHS compliance requirements. The transition to tin improves environmental compliance without affecting electrical performance.

Q: Are the contact dimensions identical between these parts?

A: Yes. Both connectors maintain identical mating contact length (0.230"), post length (0.090"), overall contact length (0.410"), and insulation height (0.090"). Physical fit and engagement depth are fully compatible.

Q: What is the significance of the product status change from obsolete to active?

A: Active product status ensures continued manufacturing, supply availability, and technical support. The 146225-3 obsolete status creates supply risk and limits future sourcing options. The 5-146283-3 active status provides long-term design security and production continuity.

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

A: No. Both connectors maintain identical current rating (3A), voltage rating (30VAC), operating temperature range (-65°C to 105°C), and contact finish specifications (gold mating surface). Electrical performance is fully equivalent.

Q: Can these connectors be used interchangeably with existing receptacles?

A: Yes. The identical 0.100" (2.54mm) pitch and 3-position single-row configuration ensure compatibility with all standard AMPMODU Mod II receptacles and existing PCB layouts designed for the 146225-3.
