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

Part Overview

The TE Connectivity ALCOSWITCH 1571920-6 is a panel-mounted toggle switch with Single Pole Double Throw (SPDT) configuration, rated for 6A at 125V AC and 4A at 28V DC. This component features an On-Off-On switch function with a standard round actuator and PC pin termination. The part is classified as obsolete, necessitating identification of active equivalent components to maintain design continuity and ensure ongoing component availability for new production and field service applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 1571920-6 is based on electrical and mechanical parameter equivalence within the TE Connectivity ALCOSWITCH product family. The substitute part MTA106EPC 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)
• Identical switch function (On-Off-On)
• Identical current and voltage ratings
• Identical mechanical mounting interface
• Identical termination style (PC Pin)
• Identical panel cutout and bushing specifications
• Identical actuator type and dimensions
• Identical operating temperature range
• Identical electrical life rating

Parameter Comparison

Engineering Selection Recommendations

The MTA106EPC serves as the direct active equivalent for the obsolete 1571920-6 based on complete electrical and mechanical parameter alignment. Both components are manufactured by TE Connectivity within the MTA Green series and provide identical functional performance across all specified electrical ratings and mechanical interfaces.

Selection of MTA106EPC for replacement applications is supported by:

• Active product status ensuring ongoing availability and supply chain continuity
• Identical electrical specifications eliminating circuit redesign requirements
• Identical mechanical mounting interface enabling direct panel retrofit without modification
• Identical termination and actuator specifications ensuring compatibility with existing wiring and mechanical assemblies

Designers should note that MTA106EPC exhibits different actuator material composition (brass with nickel plating versus copper alloy with chrome plating) and different regulatory compliance status (RoHS non-compliant, REACH affected versus REACH unaffected). These differences do not affect electrical or mechanical substitution compatibility but should be evaluated against specific application compliance requirements and material specification constraints.

Frequently Asked Questions (FAQ)

Q: Can MTA106EPC be used as a direct replacement for 1571920-6 in existing designs?

A: Yes. MTA106EPC provides complete electrical and mechanical compatibility with 1571920-6. All critical parameters including circuit configuration, current and voltage ratings, mounting interface, termination style, and actuator specifications are identical. No circuit modifications or mechanical redesign is required.

Q: What is the difference in actuator material between these parts?

A: The 1571920-6 features a copper alloy actuator with chrome plating, while the MTA106EPC features a brass actuator with nickel plating. Both materials provide equivalent electrical conductivity and mechanical durability for the specified 60,000 cycle electrical life. Material selection should be evaluated against application-specific corrosion resistance or material compatibility requirements.

Q: Are there compliance differences between these parts?

A: Yes. The 1571920-6 is listed as REACH Unaffected, while MTA106EPC is REACH Affected. Additionally, MTA106EPC is RoHS non-compliant. Applications subject to RoHS or REACH compliance requirements should evaluate these regulatory differences against applicable standards and procurement specifications.

Q: What is the panel cutout requirement for installation?

A: Both parts require an identical circular panel cutout of 6.40mm diameter with a 1/4-40 bushing thread. Existing panel preparations for 1571920-6 are compatible with MTA106EPC without modification.

Q: Are the electrical ratings identical?

A: Yes. Both parts are rated for 6A at 125V AC and 4A at 28V DC with identical SPDT circuit configuration and On-Off-On switch function. Operating temperature range (-20°C to 80°C) and electrical life (60,000 cycles) are also identical.

Q: What packaging is available for MTA106EPC?

A: MTA106EPC is supplied in bulk packaging. The original 1571920-6 packaging specification was not provided in the available documentation.
