Engineering Selection Recommendations

Direct TE Connectivity Equivalent:

The TE Connectivity 794313-3 is the primary direct equivalent to the obsolete 794313-1. Both components share identical mechanical and electrical specifications within the AMP-DUAC series. The 794313-3 maintains active product status and achieves ROHS3 compliance with REACH unaffected status, addressing regulatory requirements that the original part does not satisfy. The primary distinction is the contact finish specification: 794313-3 utilizes tin finish compared to the tin-lead finish of 794313-1. This transition aligns with industry-wide lead-free initiatives and does not compromise functional compatibility.

Molex Alternative Substitutes:

Molex rectangular connectors 0442060001, 0444722454, 0444722455, 0460152402, 0460152406, and 0469990137 provide functional equivalence across all critical mating and mounting parameters. All Molex alternatives maintain active product status and ROHS3 compliance. Selection among Molex options depends on specific application requirements:

0442060001 (Mini-Fit Jr 44206): Brass contact material, lowest contact finish thickness (35.4µin / 0.90µm), suitable for general purpose, industrial, and telecommunications applications.
0444722454 (Mini-Fit HCS 44472): Copper alloy contact material, UL94 V-2 flammability rating, moderate contact finish thickness (100.0µin / 2.54µm).
0444722455 (Mini-Fit HCS 44472): Copper alloy contact material, enhanced UL94 V-0 flammability rating, moderate contact finish thickness (100.0µin / 2.54µm), suitable for automotive, medical, and telecommunications applications.
0460152402 (Mini-Fit Plus HCS 46015): Copper alloy contact material, UL94 V-0 flammability rating, moderate contact finish thickness (100.0µin / 2.54µm), suitable for automotive, medical, and telecommunications applications.
0460152406 (Mini-Fit Plus HCS 46015): Copper alloy contact material, UL94 V-2 flammability rating, moderate contact finish thickness (100.0µin / 2.54µm), suitable for automotive, medical, and telecommunications applications.
0469990137 (Mini-Fit Jr 5566): Brass contact material, UL94 V-2 flammability rating, moderate contact finish thickness (100.0µin / 2.54µm), suitable for general purpose, industrial, and telecommunications applications.

All substitute parts are ROHS3 compliant and REACH unaffected, providing regulatory advantages over the original obsolete component.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 794313-3 be used as a direct replacement for the 794313-1?

A: Yes. The 794313-3 maintains identical mechanical and electrical specifications as the 794313-1 within the AMP-DUAC series. The primary difference is the contact finish specification (tin versus tin-lead) and improved regulatory compliance status. The 794313-3 is the recommended direct equivalent.

Q: What is the significance of the contact finish difference between the main part and substitutes?

A: The original 794313-1 uses tin-lead contact finish (118.1µin / 3.00µm thickness), while the 794313-3 and Molex alternatives use tin finish. Tin finish is compatible with lead-free solder processes and aligns with RoHS directives. Contact finish thickness variations among Molex options (35.4µin to 100.0µin) do not affect functional compatibility within the specified electrical parameters.

Q: Are Molex connectors mechanically compatible with TE Connectivity AMP-DUAC receptacles?

A: Molex rectangular connectors listed as substitutes maintain identical mating pitch (0.165" / 4.20mm), row spacing (0.165" / 4.20mm), contact shape (square), and locking ramp fastening type. These parameters ensure mechanical compatibility with corresponding receptacles designed for the original 794313-1 specification.

Q: What is the difference between the Mini-Fit Jr, Mini-Fit HCS, and Mini-Fit Plus HCS series from Molex?

A: These are distinct Molex connector series within the rectangular connector product line. All listed alternatives maintain the required 24-position, 2-row configuration with 0.165" (4.20mm) pitch and through-hole mounting. Series designation reflects internal design variations and feature sets but does not affect compatibility with the specified mating and mounting parameters.

Q: Does the UL94 V-0 flammability rating of some Molex alternatives provide an advantage over the UL94 V-2 rating of the original part?

A: UL94 V-0 represents a higher flammability performance classification than UL94 V-2. Components with UL94 V-0 rating (0444722455, 0460152402) are suitable for applications with enhanced fire safety requirements. Selection between V-0 and V-2 rated alternatives depends on specific application standards and regulatory requirements.

Q: What is the inventory status of these substitute parts?

A: All substitute parts are listed as new original in stock. The TE Connectivity 794313-3 has 967 pieces available. Molex alternatives range from 851 to 9638 pieces in inventory, with 0442060001 offering the highest availability at 9638 pieces.

Q: Are there any operating temperature or voltage rating differences among the substitutes?

A: The TE Connectivity 794313-3 maintains the original operating temperature range (-55°C ~ 105°C) and voltage rating (600VAC). Molex alternatives do not specify operating temperature or voltage ratings in the provided data. For applications requiring specific temperature or voltage performance, the TE Connectivity 794313-3 is the recommended choice.

Q: What is the significance of REACH and RoHS compliance status?

A: The original 794313-1 is RoHS non-compliant and REACH affected, indicating potential restrictions in certain markets and applications. All substitute parts are ROHS3 compliant and REACH unaffected, ensuring compliance with European Union regulations and facilitating use in regulated industries and geographic markets.

Q: Can the 794313-1 be used interchangeably with the listed Molex alternatives in existing designs?

A: Yes, within the constraints of the specified electrical and mechanical parameters. All listed substitutes maintain identical mating pitch, position count, row configuration, mounting type, shrouding, termination method, and fastening type. Existing PCB layouts and receptacle designs compatible with the 794313-1 will accommodate the listed alternatives without modification.
