Engineering Selection Recommendations

Primary Recommendation: TE Connectivity 1586039-2

The TE Connectivity 1586039-2 is the preferred direct substitute for the obsolete 1-794302-1. Both components are manufactured by TE Connectivity and share identical mechanical and electrical specifications. The 1586039-2 maintains the same connector geometry, contact configuration, and voltage rating (600VAC). The operating temperature range of -40°C to 105°C is compatible with the original specification of -55°C to 105°C for applications not requiring the extended low-temperature performance. The 1586039-2 is classified as active product status with substantial inventory availability (7269 pieces). Both parts are ROHS3 compliant and carry MSL rating of 1 (Unlimited).

Secondary Recommendations: Molex Mini-Fit Jr 5566 Series

The Molex part numbers 0469990335, 0039306025, and 0469990621 from the Mini-Fit Jr 5566 series provide functional equivalence through identical mechanical dimensions and contact configuration. These parts maintain the 2-position, 2-row header configuration with 0.165" (4.20mm) row spacing, through-hole mounting, and locking ramp fastening. All three Molex alternatives are active products with high inventory levels. The material flammability rating of UL94 V-0 exceeds the original UL94 V-2 specification, providing enhanced performance. These parts are suitable for applications where cross-manufacturer compatibility is acceptable.

Alternative Recommendation: Molex 0444720251

The Molex 0444720251 from the Mini-Fit HCS 44472 series offers functional compatibility with identical mechanical specifications. This part is classified as active with 872 pieces in inventory. The UL94 V-0 flammability rating provides superior performance compared to the original UL94 V-2 specification. This connector is suitable for automotive, industrial, medical, and telecommunications applications.

All substitute parts are ROHS3 compliant and carry MSL rating of 1 (Unlimited), meeting regulatory and environmental requirements equivalent to the original component.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1586039-2 be used as a direct replacement for the 1-794302-1?

A: Yes. The 1586039-2 is a direct substitute with identical connector type, contact configuration, row spacing, mounting method, and fastening mechanism. Both components feature 2-position, 2-row headers with 0.165" (4.20mm) row spacing, through-hole solder termination, and locking ramp fastening. The 1586039-2 is manufactured by the same company and maintains full mechanical and electrical compatibility.

Q: What is the difference between the TE Connectivity 1586039-2 and the Molex alternatives?

A: The primary differences are manufacturer and contact material composition. The TE Connectivity 1586039-2 uses brass alloy contacts, while Molex Mini-Fit Jr 5566 series parts use brass contacts, and the Molex Mini-Fit HCS 44472 uses copper alloy contacts. All parts maintain identical mechanical dimensions, row spacing, and fastening characteristics. The Molex alternatives carry UL94 V-0 flammability rating compared to UL94 V-2 for the TE Connectivity parts.

Q: Are there operating temperature differences between the main part and substitutes?

A: The original 1-794302-1 operates from -55°C to 105°C. The TE Connectivity 1586039-2 operates from -40°C to 105°C, providing a narrower low-temperature range. For applications requiring operation below -40°C, the original specification must be verified. The Molex alternatives do not specify operating temperature ranges in the provided data.

Q: What packaging options are available for these substitute parts?

A: The TE Connectivity 1586039-2 is supplied in bulk packaging. Molex alternatives are available in both bulk and tray packaging: 0469990335 and 0039306025 are supplied in trays, while 0444720251 and 0469990621 are supplied in bulk. Packaging selection depends on assembly process requirements and inventory management practices.

Q: Do all substitute parts meet RoHS and environmental compliance requirements?

A: Yes. All identified substitute parts are ROHS3 compliant and carry Moisture Sensitivity Level (MSL) rating of 1 (Unlimited), matching the compliance profile of the original 1-794302-1. The TE Connectivity 1586039-2 carries REACH Unaffected status, while Molex parts carry REACH Unaffected status, ensuring regulatory compliance across multiple jurisdictions.

Q: What is the significance of the contact material differences between substitutes?

A: Contact material variations (copper alloy, brass alloy, or brass) do not affect functional compatibility for this connector category. All materials provide adequate electrical conductivity and mechanical durability for the specified 600VAC voltage rating and solder termination method. Material selection is driven by manufacturing process and cost considerations rather than performance requirements.

Q: Can these connectors be used interchangeably in existing PCB designs?

A: Yes. All substitute parts maintain identical mechanical dimensions, including insulation height (0.504"), contact post length (0.138"), and row spacing (0.165"). PCB footprints designed for the 1-794302-1 accommodate all identified substitutes without modification. The through-hole mounting configuration and solder termination method are identical across all parts.
