Substitute Part Grouping Explanation

Substitution of the TE Connectivity 794486-1 is determined by strict equivalence across the following critical parameters: connector type (header), contact type (male pin), number of positions (8), number of rows (2), mating pitch (0.165" / 4.20mm), row spacing (0.165" / 4.20mm), mounting type (through hole), termination method (solder), shrouding configuration (shrouded 4-wall), fastening type (locking ramp), contact post length (0.138" / 3.50mm), insulation height (0.504" / 12.80mm), contact shape (square), and insulation material (polyamide/nylon).

Substitute parts are grouped into two categories:

Direct Equivalent: TE Connectivity 1-794486-1 maintains identical electrical and mechanical specifications to the original part, with the primary distinction being active product status and RoHS3 compliance.

Functional Equivalents: Molex Mini-Fit Plus HCS 46015 series (0460150802, 0460150806) and Molex Mini-Fit Jr 5566 series (0469990141, 0469990567) provide equivalent connector functionality across all critical mating and mounting parameters. These parts differ in contact material composition, insulation material specification, and flammability ratings while maintaining full mechanical and electrical interchangeability.

Engineering Selection Recommendations

Direct Equivalent Selection: The TE Connectivity 1-794486-1 is the primary recommended substitute for the obsolete 794486-1. This part maintains identical mechanical and electrical specifications while offering active product status and ROHS3 compliance. The transition from tin-lead to tin contact finish aligns with current RoHS requirements and does not compromise electrical performance or mechanical interchangeability.

Functional Equivalent Selection: Molex Mini-Fit Plus HCS 46015 series connectors (0460150802, 0460150806) and Molex Mini-Fit Jr 5566 series connectors (0469990141, 0469990567) provide full mechanical and electrical interchangeability across all critical mating and mounting parameters. These parts are suitable for applications where the original TE Connectivity specification is not mandated by design documentation.

Compliance Considerations: All substitute parts listed are ROHS3 compliant and REACH unaffected, addressing regulatory requirements for new designs and procurement. The original 794486-1 is RoHS non-compliant and carries vendor-undefined REACH status, making transition to compliant alternatives necessary for ongoing production.

Flammability Rating Variance: Part 0460150806 carries a UL94 V-2 flammability rating compared to the UL94 V-0 rating of the original part and other substitutes. Applications requiring UL94 V-0 certification should select 0460150802, 0469990141, or 0469990567.

Contact Material Variance: Molex Mini-Fit Jr 5566 series parts (0469990141, 0469990567) utilize brass contact material compared to copper alloy in the original and other substitutes. This material difference does not affect electrical performance or mechanical compatibility for standard applications.

Insulation Color Variance: Part 0469990567 features black insulation compared to natural insulation in all other parts. This is a cosmetic distinction with no impact on electrical or mechanical function.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1-794486-1 be used as a direct replacement for the obsolete 794486-1?

A: Yes. The 1-794486-1 maintains identical electrical and mechanical specifications across all critical parameters including connector type, position count, pitch, mounting configuration, and termination method. The primary differences are active product status and RoHS3 compliance. The contact finish transition from tin-lead to tin does not affect electrical performance or mechanical interchangeability.

Q: Are Molex Mini-Fit Plus HCS 46015 and Mini-Fit Jr 5566 series connectors mechanically compatible with the original TE Connectivity 794486-1?

A: Yes. All Molex substitute parts listed maintain identical mating pitch (0.165" / 4.20mm), row spacing (0.165" / 4.20mm), contact post length (0.138" / 3.50mm), insulation height (0.504" / 12.80mm), shrouding configuration (shrouded 4-wall), and fastening type (locking ramp). These parameters determine mechanical interchangeability with mating connectors and PCB layouts designed for the original part.

Q: What is the difference between the Molex Mini-Fit Plus HCS 46015 and Mini-Fit Jr 5566 series?

A: The primary differences are contact material composition and series designation. Mini-Fit Plus HCS 46015 parts (0460150802, 0460150806) utilize copper alloy contacts, while Mini-Fit Jr 5566 parts (0469990141, 0469990567) utilize brass contacts. Both series maintain identical mating and mounting specifications. Part 0460150806 carries a UL94 V-2 flammability rating compared to UL94 V-0 for other parts.

Q: Does the contact finish change from tin-lead to tin affect electrical performance?

A: No. The transition from tin-lead to tin contact finish does not affect electrical conductivity, contact resistance, or signal integrity. This change reflects current RoHS compliance requirements and is standard across modern connector manufacturing.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed (1-794486-1, 0460150802, 0460150806, 0469990141, 0469990567) are ROHS3 compliant. The original 794486-1 is RoHS non-compliant, making transition to compliant alternatives necessary for new designs and ongoing procurement.

Q: What is the significance of the UL94 V-0 versus UL94 V-2 flammability rating?

A: UL94 V-0 represents a higher flammability performance standard than UL94 V-2. Applications requiring UL94 V-0 certification should select parts 1-794486-1, 0460150802, 0469990141, or 0469990567. Part 0460150806 carries UL94 V-2 rating and is suitable for applications with less stringent flammability requirements.

Q: Does insulation color affect connector function?

A: No. Insulation color is a cosmetic specification with no impact on electrical performance or mechanical function. Part 0469990567 features black insulation while all other parts feature natural insulation. Selection based on color is a design preference consideration only.

Q: What is the Moisture Sensitivity Level (MSL) rating and why is it relevant?

A: All parts listed carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage, handling, or assembly. This specification is identical across all parts and does not differentiate substitute selection.

Q: Are operating temperature specifications available for all substitute parts?

A: The original 794486-1 and direct equivalent 1-794486-1 specify operating temperature range of -55°C to 105°C. Molex substitute parts do not provide operating temperature specifications in the available data. Applications with specific temperature requirements should reference detailed manufacturer datasheets or contact suppliers for complete thermal specifications.

Q: Are voltage ratings specified for all substitute parts?

A: The original 794486-1 and direct equivalent 1-794486-1 specify 600VAC voltage rating. Molex substitute parts do not provide voltage rating specifications in the available data. Applications with specific voltage requirements should reference detailed manufacturer datasheets or contact suppliers for complete electrical specifications.
