TE Connectivity ALCOSWITCH 1571920-5 Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The TE Connectivity ALCOSWITCH 1571920-5 is a panel-mount toggle switch with SPDT (Single Pole Double Throw) circuit configuration, rated for 6A at 125V AC and 4A at 28V DC. This component features a standard round actuator with epoxy sealed terminals and operates across a temperature range of -20°C to 80°C. The 1571920-5 is classified as obsolete, necessitating identification of active equivalent parts to ensure continued availability and supply chain continuity for new designs and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 1571920-5 is based on electrical and mechanical parameter equivalence within the TE Connectivity ALCOSWITCH product family. The substitute part MTA106E maintains identical electrical specifications including SPDT circuit configuration, 6A AC / 4A DC current ratings, 125V AC / 28V DC voltage ratings, and mechanical compatibility through matching panel cutout dimensions (6.40mm circular), bushing thread specification (1/4-40), and actuator geometry (standard round, 10.49mm length).

The substitution is valid based on the following critical parameters:

• Identical circuit topology (SPDT On-Off-On)
• Matching current and voltage ratings
• Equivalent mechanical mounting interface
• Identical termination style (solder lug)
• Matching operating temperature range
• Equivalent electrical life specification
• Same series family (MTA Green)

Parameter Comparison

Engineering Selection Recommendations

The MTA106E serves as the direct active equivalent for the obsolete 1571920-5. Selection of MTA106E is supported by the following engineering considerations:

Product Status: The 1571920-5 is classified as obsolete, while MTA106E maintains active product status with current manufacturing and supply availability.

Electrical Equivalence: Both parts maintain identical electrical specifications across all critical parameters including circuit configuration, current ratings, voltage ratings, and electrical life cycles.

Mechanical Compatibility: Panel mounting interfaces are identical, including cutout dimensions, bushing thread specification, and actuator geometry, enabling direct mechanical substitution without enclosure redesign.

Compliance Enhancement: MTA106E provides ROHS3 compliance certification, representing an improvement over the original part specification. Both parts share the same ECCN and HTSUS classifications.

Regulatory Alignment: While the original part is REACH Unaffected, MTA106E is REACH Affected, reflecting current regulatory requirements for active components in the market.

Actuator Material Difference: The original 1571920-5 features a copper alloy chrome-plated actuator, while MTA106E uses brass with nickel plating. Both materials provide equivalent electrical and mechanical performance within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can MTA106E be used as a direct replacement for 1571920-5 in existing designs?
