TE Connectivity 1-794429-1 Rectangular Connector Header Equivalent & Substitute Parts

Part Overview

The TE Connectivity 1-794429-1 is a shrouded rectangular connector header designed for through-hole mounting in board-to-board or cable applications. This 16-position, 2-row connector operates across a temperature range of -55°C to 105°C and features a 0.165" (4.20mm) pitch configuration with tin-plated copper alloy contacts. The part is classified as obsolete, necessitating identification of active equivalent components that maintain electrical and mechanical compatibility for continued system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 1-794429-1 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Header
• Contact Type: Male Pin
• Number of Positions: 16
• Number of Rows: 2
• Pitch - Mating: 0.165" (4.20mm)
• Row Spacing - Mating: 0.165" (4.20mm)
• Shrouding: Shrouded - 4 Wall
• Mounting Type: Through Hole
• Termination: Solder
• Fastening Type: Locking Ramp
• Insulation Height: 0.504" (12.80mm)
• Contact Shape: Square
• Contact Finish - Mating: Tin
• Operating Temperature: -55°C ~ 105°C

The identified substitute parts maintain full compatibility across all mandatory parameters. Variations in secondary attributes such as contact material composition, contact finish thickness, flammability rating, and manufacturer series do not preclude functional substitution when the primary electrical and mechanical specifications remain constant.

Engineering Selection Recommendations

TE Connectivity 1-1586489-6 (Primary Substitute)

The 1-1586489-6 represents the direct equivalent within the TE Connectivity AMP-DUAC series. This part maintains active product status and carries full RoHS compliance certification. All electrical and mechanical parameters align precisely with the original 1-794429-1 specification. The material flammability rating differs at UL94 V-2 versus the original V-0 classification; however, this represents an acceptable trade-off given the active availability and identical functional performance across all critical mating and mounting parameters. This substitute is suitable for direct replacement in existing designs and new implementations.

Molex 0039299162 (Secondary Substitute)

The 0039299162 from the Molex Mini-Fit Jr 5566 series provides functional equivalence across all mandatory electrical and mechanical parameters. This part maintains active product status and ROHS3 compliance. The contact material composition differs (brass versus copper alloy) and the contact finish thickness is reduced (35.4µin versus 118.1µin). The operating temperature and voltage rating specifications are not provided for this component. Selection of this substitute requires confirmation that the reduced contact finish thickness and unspecified thermal/voltage parameters are acceptable for the intended application. This part is available in higher inventory quantity (4152 units) compared to the TE Connectivity alternative.

Frequently Asked Questions (FAQ)

Q: Can the 1-1586489-6 be used as a direct replacement for the 1-794429-1?

A: Yes. The 1-1586489-6 maintains identical electrical and mechanical specifications across all critical parameters including pitch, row spacing, contact configuration, mounting type, and termination method. The primary difference is product status (active versus obsolete) and flammability rating (UL94 V-2 versus V-0). Both parts are TE Connectivity AMP-DUAC series components with full RoHS compliance.

Q: What are the key differences between the TE Connectivity and Molex substitutes?

A: Both substitutes maintain identical pitch (0.165"), position count (16), row configuration (2), and mounting specifications. Differences include: manufacturer series (AMP-DUAC versus Mini-Fit Jr 5566), contact material (copper alloy versus brass), contact finish thickness (118.1µin versus 35.4µin), and insulation material specification (PA/Nylon versus PA66/Nylon 6/6). The Molex part does not specify operating temperature or voltage rating parameters.

Q: Are there packaging differences between these parts?

A: The TE Connectivity 1-794429-1 and 1-1586489-6 do not specify packaging format. The Molex 0039299162 is supplied in tray packaging. Packaging format does not affect electrical or mechanical compatibility.

Q: Can the Molex 0039299162 be used in applications requiring the original 600VAC voltage rating?

A: The Molex 0039299162 does not specify a voltage rating in the provided data. Confirmation of voltage capability is required before selection for applications with defined voltage requirements such as the original 600VAC specification.

Q: Does the reduced contact finish thickness on the Molex part affect reliability?

A: The Molex 0039299162 specifies 35.4µin (0.90µm) contact finish thickness compared to 118.1µin (3.00µm) on the TE Connectivity parts. Both finishes are tin-plated. The functional impact of this difference depends on application-specific requirements for contact durability and mating cycle life. Engineering evaluation is necessary for applications with high mating cycle requirements.

Q: Are all three parts RoHS compliant?

A: The 1-794429-1 and 0039299162 are ROHS3 compliant. The 1-1586489-6 carries RoHS compliance certification. All three parts are REACH unaffected and classified under ECCN EAR99.

Q: What is the inventory status for each substitute?

A: The 1-794429-1 (obsolete) has 1098 units in stock. The 1-1586489-6 (active) has 727 units available. The 0039299162 (active) has 4152 units in stock, representing the highest availability option.
