TE Connectivity 2-146256-0 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 2-146256-0 is a rectangular connector header manufactured under the AMPMODU Mod II series. This through-hole connector features 40 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, suitable for applications requiring 3A current capacity across an operating temperature range of -65°C to 105°C.

The 2-146256-0 carries an obsolete product status. Locating equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or repair requirements for legacy systems utilizing this connector specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2-146256-0 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications in the following categories:

Connector Architecture: Connector type (Header, Breakaway), contact type (Male Pin), number of positions (40), number of rows (2), and pitch spacing (0.100" / 2.54mm mating pitch and row spacing).

Physical Dimensions: Contact length specifications (mating: 0.230", post: 0.120", overall: 0.440"), insulation height (0.090"), and contact shape (Square) must be identical.

Electrical Performance: Current rating (3A), operating temperature range (-65°C to 105°C), and contact material (Copper Alloy) must match exactly.

Material & Finish Specifications: Insulation material (Liquid Crystal Polymer), contact finish on mating surface (Gold), contact shape (Square), and material flammability rating (UL94 V-0) must be preserved.

Compliance & Environmental: RoHS compliance status and Moisture Sensitivity Level (MSL 1) must be maintained.

The substitute part 7-146256-0 meets all these criteria and is therefore a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The 7-146256-0 is the direct substitute for the obsolete 2-146256-0. Both parts are manufactured by TE Connectivity under the AMPMODU Mod II series and share identical electrical, mechanical, and dimensional specifications across all critical parameters.

The primary distinction between these parts is product status: the 2-146256-0 is obsolete, while the 7-146256-0 maintains active production status. This status difference, combined with the 7-146256-0's significantly higher inventory availability (6549 pieces versus 711 pieces), establishes it as the recommended substitute for new designs and ongoing production requirements.

Both parts maintain RoHS compliance and carry identical compliance certifications (EAR99, HTSUS 8536.69.4040). The contact finish on the post differs slightly (Tin-Lead versus Tin); however, this difference does not affect functional compatibility or electrical performance within the specified operating parameters.

The 7-146256-0 is supplied in bulk packaging, whereas the 2-146256-0 packaging specification is not provided. For applications requiring the original packaging format, this distinction should be evaluated against supply chain and inventory management requirements.

Frequently Asked Questions (FAQ)

Q: Can the 7-146256-0 be used as a direct replacement for the 2-146256-0 in existing designs?

A: Yes. The 7-146256-0 is electrically and mechanically equivalent to the 2-146256-0. All critical parameters including connector type, position count, pitch spacing, contact dimensions, current rating, and operating temperature range are identical. The parts are interchangeable at the board level.

Q: What is the difference between the contact finishes on these two parts?

A: The 2-146256-0 features tin-lead post finish, while the 7-146256-0 features tin post finish. Both finishes provide equivalent solderability and electrical performance. The tin finish on the 7-146256-0 reflects modern RoHS-compliant manufacturing practices.

Q: Why is the 2-146256-0 listed as obsolete?

A: The 2-146256-0 has been discontinued by TE Connectivity. The 7-146256-0 represents the current production equivalent within the AMPMODU Mod II series and is the recommended part for new procurement.

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

A: Both parts maintain identical RoHS compliance status, UL94 V-0 flammability rating, and export classification (EAR99). Compliance certifications are equivalent.

Q: What packaging differences exist between these parts?

A: The 7-146256-0 is supplied in bulk packaging. The original packaging specification for the 2-146256-0 is not documented. Bulk packaging is standard for active production parts and supports high-volume assembly operations.

Q: Can the 7-146256-0 be used in applications originally designed for the 2-146256-0?

A: Yes. The 7-146256-0 maintains full compatibility with applications designed for the 2-146256-0. All mating dimensions, electrical ratings, and environmental specifications are preserved.

Q: What is the inventory status of the 7-146256-0?

A: The 7-146256-0 is in active production with 6549 pieces currently in stock, providing reliable supply availability for both new designs and replacement requirements.
