TE Connectivity ALCOSWITCH 2-1571920-6 Toggle Switch DPDT Equivalent & Substitute Parts

Part Overview

The TE Connectivity ALCOSWITCH 2-1571920-6 is a panel-mounted toggle switch with DPDT (Double Pole Double Throw) circuit configuration, rated for 6A AC at 125V and 4A DC at 28V. This component operates in a Mom-Off-Mom (momentary-off-momentary) switch function with non-illuminated standard round actuator. The part is classified as obsolete, necessitating identification of active equivalent components that maintain identical electrical and mechanical specifications for continued system integration and maintenance applications.

Substitute Part Grouping Explanation

Substitution of the obsolete 2-1571920-6 with the active MTA206SPC is based on strict equivalence across all critical electrical and mechanical parameters. Both components share identical circuit configuration (DPDT), switch function (Mom-Off-Mom), current ratings (6A AC / 4A DC), voltage ratings (125V AC / 28V DC), mounting methodology (panel mount), termination style (PC pin), actuator specifications (standard round, 10.49mm length), bushing thread size (1/4-40), operating temperature range (-20°C to 80°C), and terminal sealing features (epoxy sealed). The MTA206SPC maintains full functional and physical compatibility while offering active product status and current manufacturing support.

Parameter Comparison

Engineering Selection Recommendations

The MTA206SPC serves as the direct active equivalent for the obsolete 2-1571920-6. Selection of the MTA206SPC is supported by complete electrical and mechanical parameter equivalence across all critical specifications. The substitute component offers enhanced product status as an active manufactured part with current supply chain availability. The MTA206SPC provides ROHS3 compliance, representing improved environmental and regulatory alignment compared to the original obsolete component. Both components maintain identical performance characteristics within the specified operating envelope of -20°C to 80°C and deliver equivalent electrical performance at rated current and voltage levels. The MTA206SPC is suitable for direct replacement in applications requiring DPDT momentary switching functionality at 6A AC / 4A DC ratings with panel-mount configuration.
