TE Connectivity 2-146257-5 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 2-146257-5 is a rectangular connector header manufactured under the AMPMODU Mod II series. This through-hole connector features 50 positions arranged in 2 rows with 0.100" (2.54mm) pitch spacing, designed for board-to-board or cable applications. The connector utilizes male pin contacts with gold-plated mating surfaces and tin-lead post finishes, rated for 3A current at operating temperatures between -65°C and 105°C.

The 2-146257-5 carries an obsolete product status. Identification of equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support legacy system maintenance where this connector type remains in active use.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 2-146257-5 is determined by strict equivalence across the following critical parameters:

Mechanical Compatibility:

• Connector type (Header, Breakaway)
• Contact type (Male Pin)
• Number of positions (50)
• Number of rows (2)
• Pitch spacing (0.100" / 2.54mm mating and row spacing)
• Mounting type (Through Hole)
• Termination method (Solder)

Electrical Performance:

• Current rating (3A minimum)
• Operating temperature range (-65°C to 105°C)
• Contact material (Copper Alloy)

Regulatory & Environmental:

• RoHS Compliance status
• Flammability rating (UL94 V-0)
• Insulation material (Liquid Crystal Polymer)

The substitute part 7-146257-5 maintains identical specifications across all mechanical, electrical, and regulatory parameters. The primary distinction is product status (Active versus Obsolete) and packaging configuration (Bulk versus standard packaging).

Parameter Comparison

Engineering Selection Recommendations

The 7-146257-5 serves as the direct functional equivalent to the obsolete 2-146257-5. Both parts are manufactured by TE Connectivity under the AMPMODU Mod II series and maintain identical electrical, mechanical, and regulatory specifications.

Product Status Consideration: The 2-146257-5 carries obsolete status, indicating discontinued manufacturing and limited availability. The 7-146257-5 maintains active product status with confirmed inventory availability (2182 pieces in stock), ensuring reliable supply for new designs and legacy system support.

Compliance & Certification: Both parts maintain RoHS Compliance and UL94 V-0 flammability certification. The contact finish difference (Tin-Lead versus Tin) does not affect functional compatibility, as both finishes provide equivalent electrical performance and solder joint reliability within the specified operating parameters.

Packaging Consideration: The 7-146257-5 is supplied in Bulk packaging, which may differ from the original packaging configuration of the 2-146257-5. Bulk packaging does not affect connector performance or mechanical compatibility; it reflects only the distribution format.

For applications requiring the 50-position, 2-row, 0.100" pitch header connector with through-hole solder termination, the 7-146257-5 provides complete functional substitution with the advantage of active product status and current manufacturing support.

Frequently Asked Questions (FAQ)
