TE Connectivity AMP Connectors 794354-1 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 794354-1 is a rectangular connector header designed for through-hole mounting applications. This connector features a vertical orientation with 12 positions arranged in 2 rows, utilizing a 4.2mm (0.165") pitch configuration. The connector is classified as a shrouded 4-wall header with male pin contacts and solder termination, suitable for board-to-board or cable interconnection.

The original 794354-1 carries an obsolete product status, which necessitates identification of active equivalent alternatives to ensure continued availability and supply chain reliability for new designs and production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of rectangular connector headers is determined by strict equivalence across mechanical and electrical parameters. The following criteria establish valid substitution relationships for the 794354-1:

Critical Matching Parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (12)
• Number of rows (2)
• Pitch - mating (0.165" / 4.20mm)
• Row spacing - mating (0.165" / 4.20mm)
• Shrouding configuration (Shrouded - 4 Wall)
• Mounting type (Through Hole)
• Termination method (Solder)
• Fastening type (Locking Ramp)
• Insulation height (0.504" / 12.80mm)
• Contact shape (Square)
• Contact material (Copper Alloy)
• Insulation material (Polyamide / Nylon)
• Operating temperature range (-55°C ~ 105°C)
• Voltage rating (600VAC)
• Flammability rating (UL94 V-2)

Parts meeting all these criteria are electrically and mechanically interchangeable. Variations in contact finish composition (tin-lead versus tin) do not affect substitution eligibility when all other parameters remain constant.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 1-794354-1 serves as the direct active equivalent to the obsolete 794354-1. Both parts share identical mechanical and electrical specifications across all critical parameters, including connector configuration, pitch, mounting type, and operating characteristics.

The primary distinction between these parts is product status and regulatory compliance. The 794354-1 is classified as obsolete with RoHS non-compliant status, while the 1-794354-1 maintains active product status with RoHS compliance. The 1-794354-1 also carries defined REACH status (REACH Unaffected) compared to the vendor-undefined status of the original part.

Contact finish composition differs between the two parts: the 794354-1 uses tin-lead plating, while the 1-794354-1 uses tin plating. Both finishes maintain identical thickness specifications (118.1µin / 3.00µm) and provide equivalent electrical and mechanical performance.

For new designs and ongoing production, the 1-794354-1 is the appropriate selection due to its active availability, RoHS compliance, and defined regulatory status. Existing designs utilizing the 794354-1 can transition to the 1-794354-1 without modification to PCB layouts, mating connectors, or assembly procedures.
