Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1-794528-1 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Number of Positions: 6
• Number of Rows: 2
• Pitch - Mating: 0.165" (4.20mm)
• Row Spacing - Mating: 0.165" (4.20mm)
• Connector Type: Header
• Contact Type: Male Pin
• Mounting Type: Through Hole, Right Angle
• Shrouding: Shrouded - 4 Wall
• Termination: Solder
• Fastening Type: Locking Ramp
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

All three substitute parts (1586042-6, 1586044-6, and 0353180620) satisfy these mandatory parameters. Variations in contact material composition, insulation height, contact post length, and operating temperature ranges remain within acceptable engineering tolerances for board-to-cable/wire applications. The substitute parts transition from the obsolete AMP-DUAC series to active VAL-U-LOK and Mini-Fit Jr series offerings, ensuring long-term component availability and supply chain continuity.

Parameter Comparison

Engineering Selection Recommendations

TE Connectivity 1586042-6 (VAL-U-LOK Series)

This substitute maintains full electrical and mechanical compatibility with the 1-794528-1. The part is active in production status with robust inventory availability. Both components share identical pitch spacing, position count, shrouding configuration, and fastening mechanism. The 1586042-6 operates across a -40°C to 105°C temperature range, which encompasses the majority of industrial applications. UL94 V-0 flammability rating and ROHS3 compliance ensure regulatory alignment. The brass alloy contact material and 9A current rating provide enhanced performance characteristics for general purpose, industrial, and lighting applications.

TE Connectivity 1586044-6 (VAL-U-LOK Series)

This alternative offers identical core specifications to the 1586042-6 with the addition of a mounting flange feature. The flange provides mechanical stability in board-mounted configurations. Active product status and highest inventory level (2060 units) ensure supply chain reliability. The 1586044-6 maintains UL94 V-0 compliance and operates within the same temperature and voltage parameters as the 1586042-6. Selection of this variant is appropriate when mechanical mounting reinforcement is required.

Molex 0353180620 (Mini-Fit Jr 35318 Series)

This cross-manufacturer substitute provides functional equivalence with extended contact post length (0.173" versus 0.138" on the original part). The Mini-Fit Jr series represents an industry-standard connector platform with broad application support. ROHS3 compliance and unlimited moisture sensitivity rating align with regulatory requirements. The UL94 V-2 flammability rating differs from the V-0 specification of the main part and TE alternatives. Selection of this part is appropriate for applications where cross-manufacturer standardization is beneficial and the V-2 rating is acceptable.

Frequently Asked Questions (FAQ)

Q: Can the 1586042-6 directly replace the 1-794528-1 in existing designs?

A: Yes. Both parts share identical pitch spacing (0.165" / 4.20mm), position count (6), row configuration (2), mounting type (through-hole right-angle), shrouding (4-wall), and fastening mechanism (locking ramp). The 1586042-6 is electrically and mechanically compatible for board-to-cable/wire applications.

Q: What is the primary difference between the 1586042-6 and 1586044-6?

A: The 1586044-6 includes a mounting flange feature for enhanced mechanical stability. Both parts are otherwise identical in electrical specifications, pitch, position count, and operating parameters. Selection depends on whether the mounting flange is required for the application.

Q: Why does the Molex 0353180620 have a different flammability rating?

A: The Molex part carries a UL94 V-2 rating compared to the UL94 V-0 rating of the TE Connectivity alternatives. This reflects different material formulations within the Mini-Fit Jr series. Applications requiring V-0 compliance should select the TE Connectivity options.

Q: Are there temperature range differences between substitutes?

A: The 1-794528-1 operates from -55°C to 105°C. The TE Connectivity substitutes (1586042-6 and 1586044-6) operate from -40°C to 105°C. The Molex part does not specify an operating temperature range. For applications requiring -55°C operation, the original part or equivalent specifications must be confirmed with the manufacturer.

Q: What packaging options are available?

A: The 1586042-6 and 1586044-6 are supplied in tray packaging. The Molex 0353180620 is supplied in bulk packaging. Packaging selection may impact handling, storage, and procurement workflows.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The 1-794528-1, 1586042-6, 1586044-6, and 0353180620 are all ROHS3 compliant. All parts carry unlimited moisture sensitivity level (MSL 1) classification.

Q: Which substitute offers the highest inventory availability?

A: The Molex 0353180620 has the highest inventory level at 2818 units in stock, followed by the 1586044-6 at 2060 units and the 1586042-6 at 1148 units.

Q: Can the contact post length variation affect board design?

A: The 1-794528-1 has a contact post length of 0.138" (3.50mm). The TE Connectivity substitutes have 0.142" (3.60mm) posts, and the Molex part has 0.173" (4.40mm) posts. These variations are within standard PCB design tolerances for through-hole solder applications but should be verified against specific board thickness and solder joint requirements.
