TE Connectivity 2-794630-2 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 2-794630-2 is a rectangular connector header classified as a Micro MATE-N-LOK series component. This through-hole mounted connector features 22 positions arranged in 2 rows with 0.118" (3.00mm) pitch spacing, designed for board-to-cable/wire applications. The connector utilizes shrouded 4-wall construction with press-fit and solder termination options, supporting a 250V voltage rating across an operating temperature range of -40°C to 105°C.

The 2-794630-2 carries an obsolete product status, necessitating identification of functionally equivalent alternatives for ongoing design support and procurement requirements. Direct substitutes maintain identical electrical and mechanical specifications while offering improved availability and compliance status.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2-794630-2 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part 5-794630-2 maintains identical specifications in the following key areas:

Electrical Parameters: Voltage rating (250V), current rating variability by wire gauge, and operating temperature range (-40°C to 105°C) are identical between the main part and substitute.

Mechanical Parameters: Both parts share identical connector type (Header), contact type (Male Pin), position count (22), row configuration (2 rows), mating pitch (0.118"/3.00mm), row spacing (0.118"/3.00mm), mounting method (Through Hole), shrouding style (Shrouded - 4 Wall), and termination options (Press-Fit, Solder).

Physical Dimensions: Contact post length (0.125"/3.18mm), insulation height (0.364"/9.25mm), contact shape (Square), and contact finish thickness (100.0µin/2.54µm) are identical.

Material Specifications: Both parts utilize brass contact material, polyamide (PA) nylon insulation, and UL94 V-0 flammability rating with black insulation color.

The primary distinction between parts is the contact finish composition and product status, with the substitute offering improved compliance and availability.
