Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete TE Connectivity 1-794526-1 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Header
• Contact Type: Male Pin
• Number of Positions: 2
• Number of Rows: 2
• Row Spacing - Mating: 0.165" (4.20mm)
• Mounting Type: Through Hole, Right Angle
• Shrouding: Shrouded - 4 Wall
• Termination: Solder
• Fastening Type: Locking Ramp
• Voltage Rating: 600VAC
• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The substitute part TE Connectivity 1586042-2 satisfies all mandatory matching parameters. Variations in contact material (Copper Alloy versus Brass Alloy), contact finish thickness, insulation height, and operating temperature range are within acceptable engineering tolerances for this connector category and do not preclude functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 1586042-2 is the qualified substitute for the obsolete 1-794526-1. Selection of this substitute is supported by the following engineering criteria:

Product Status: The 1586042-2 maintains active product status with current manufacturing support, ensuring long-term availability and supply chain continuity compared to the obsolete 1-794526-1.

Compliance and Certifications: Both parts maintain identical compliance profiles: ROHS3 Compliant, REACH Unaffected, and UL94 V-0 material flammability rating. Moisture Sensitivity Level 1 (Unlimited) is consistent across both parts, eliminating handling and storage requirement changes.

Electrical and Mechanical Equivalence: The substitute part matches all critical electrical parameters (600VAC voltage rating) and mechanical specifications (2-position, 2-row configuration with 0.165" row spacing, through-hole right-angle mounting, shrouded 4-wall design, solder termination, and locking ramp fastening).

Contact Material Variation: The substitute employs Brass Alloy contacts in place of Copper Alloy. Both materials are standard in rectangular connector applications and provide equivalent electrical conductivity and reliability performance for this connector category.

Operating Temperature Range: The substitute operates across -40°C to 105°C, compared to the main part's -55°C to 105°C range. For applications requiring operation below -40°C, the original part specification must be retained.

Frequently Asked Questions (FAQ)

Q: Can the 1586042-2 be used as a direct replacement for the 1-794526-1 in existing designs?

A: The 1586042-2 is mechanically and electrically compatible with the 1-794526-1 for applications operating within the -40°C to 105°C temperature range. Both parts share identical connector type, position count, row spacing, mounting configuration, shrouding, termination method, and fastening mechanism. Designs requiring operation below -40°C must retain the original 1-794526-1 specification.

Q: What is the difference in contact material between these parts?

A: The 1-794526-1 uses Copper Alloy contacts, while the 1586042-2 uses Brass Alloy contacts. Both materials provide equivalent electrical performance and reliability in rectangular connector applications. The contact finish (Tin) is identical on both parts.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain identical compliance status: ROHS3 Compliant, REACH Unaffected, UL94 V-0 material flammability rating, and Moisture Sensitivity Level 1 (Unlimited). No additional handling, storage, or qualification procedures are required when transitioning from the main part to the substitute.

Q: What packaging differences exist between these parts?

A: The 1-794526-1 packaging specification is not provided in the technical data. The 1586042-2 is supplied in Tray packaging. Confirm packaging requirements with your procurement or supply chain department to ensure compatibility with assembly processes.

Q: Why is the 1-794526-1 listed as obsolete?

A: The 1-794526-1 is classified as obsolete by TE Connectivity. The 1586042-2, part of the active VAL-U-LOK series, is the current production equivalent and is recommended for new designs and ongoing production support.

Q: Are there any applications where the 1586042-2 cannot replace the 1-794526-1?

A: The 1586042-2 cannot be used in applications requiring operation below -40°C, as its minimum operating temperature is -40°C compared to the original part's -55°C minimum. For cryogenic or extreme cold-temperature applications, the original 1-794526-1 specification must be retained or alternative parts evaluated.
