AHES4293 General Purpose Relay 3PST 35A 48VDC

Part Overview

The AHES4293 is a general purpose relay manufactured by Panasonic Electric Works, configured as a 3PST relay with 2 Form A and 1 Form B contact arrangement. The relay operates on a 48VDC coil with a contact rating of 35A at 277VAC nominal switching voltage. This through-hole mounted component is designed for applications requiring sealed, flux-protected switching in industrial and control circuits. The part is currently active in production with RoHS compliance and unlimited moisture sensitivity rating (MSL 1).

Equivalent substitute parts may be required due to inventory availability, supply chain considerations, or design revision updates while maintaining identical electrical and mechanical performance characteristics.

Key Parameters

Substitute Part Grouping Explanation

The AHES4193 qualifies as a parametric equivalent to the AHES4293 based on strict alignment of all critical electrical and mechanical parameters. Substitution eligibility is determined by the following key parameters:

• Coil voltage specification (48VDC)
• Contact form configuration (3PST-2NO/1NC)
• Contact current rating (35A)
• Switching voltage rating (277VAC nominal)
• Mounting type (Through Hole)
• Termination style (PC Pin)
• Operating temperature range (-40°C to 55°C)
• Contact material composition (Silver Tin Oxide)
• Seal rating (Sealed - Flux Protection)
• Coil insulation class (Class F)
• RoHS compliance status

Both parts belong to the Panasonic Electric Works HE-S relay series and maintain identical functional specifications, enabling direct substitution in circuit designs without modification to PCB layouts or control logic.

Parameter Comparison
