Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 794682-4 is determined by strict alignment with the following critical parameters: connector type (Header), contact type (Male Pin), number of positions (4), number of rows (2), mating pitch (0.118" / 3.00mm), row spacing (0.118" / 3.00mm), mounting type (Through Hole), shrouding configuration (Shrouded - 4 Wall), style (Board to Cable/Wire), termination method (Solder), fastening type (Locking Ramp), contact shape (Square), contact material (Brass), and insulation material composition.

Substitute parts are grouped into two categories:

Direct Equivalent: Part 3-794682-4 from TE Connectivity AMP Connectors maintains identical electrical and mechanical specifications to the main part, with the primary distinction being Active product status and ROHS3 compliance. This part represents a direct replacement with enhanced regulatory compliance.

Similar Substitutes: Parts 0430450414, 0440670401, 0440670402, and 0440670403 from Molex maintain core functional parameters including connector type, contact type, position count, row configuration, mating pitch, row spacing, mounting type, shrouding, style, termination, fastening type, contact shape, and contact material. These parts introduce variations in insulation material (Liquid Crystal Polymer with glass fill versus Polyamide/Nylon), contact post length (0.158" / 4.01mm versus 0.125" / 3.18mm), insulation height (0.390" / 9.91mm versus 0.364" / 9.25mm), and contact finish specifications. All substitute parts maintain UL94 V-0 flammability rating and MSL 1 classification.

The 3-794682-4 holds Active product status, ensuring ongoing availability and supply chain continuity. This part achieves ROHS3 compliance and REACH Unaffected status, meeting current regulatory requirements. The primary distinction from the main part is the elimination of tin-lead contact finish on the post, replaced with tin finish, and enhanced regulatory compliance documentation. Inventory availability of 21,530 pieces supports production requirements.

Secondary Selection: 0430450414 (Molex Micro-Fit 3.0 43045)

The Molex 0430450414 provides functional substitution with documented parameter variations. This part maintains core connector architecture, position count, pitch, and mounting characteristics. The insulation material differs, utilizing Liquid Crystal Polymer with glass fill instead of Polyamide/Nylon, providing enhanced thermal and mechanical properties. The contact post length remains at 0.125" (3.18mm), matching the main part specification. The voltage rating increases to 600V, exceeding the 250V specification of the main part. Current rating is specified at 8A. This part is suitable for applications requiring enhanced material performance and higher voltage margins. Active product status and ROHS3 compliance are confirmed.

Tertiary Selection: 0440670401, 0440670402, 0440670403 (Molex Micro-Fit 3.0 44067)

The Molex 0440670401, 0440670402, and 0440670403 parts provide functional substitution with extended contact post length of 0.158" (4.01mm), representing a 0.033" (0.83mm) increase from the main part specification. These parts utilize Liquid Crystal Polymer insulation material with glass fill. Mated stacking height is specified at 17.27mm. Contact finish variations exist: 0440670401 features tin mating finish, while 0440670402 and 0440670403 feature gold mating finish with differing thickness specifications (15.0µin and 30.0µin respectively).
