TE Connectivity ALCOSWITCH 1571920-9 Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The TE Connectivity ALCOSWITCH 1571920-9 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 momentary-off-momentary (Mom-Off-Mom) switch function with a standard round actuator and solder lug termination. The 1571920-9 is classified as obsolete, necessitating identification of active equivalent parts 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 1571920-9 is based on electrical and mechanical parameter equivalence within the TE Connectivity ALCOSWITCH MTA Green series. The substitute part MTA106G maintains identical electrical specifications including SPDT circuit configuration, 6A AC / 4A DC current ratings, 125V AC / 28V DC voltage ratings, and Mom-Off-Mom switch function. Mechanical compatibility is preserved through matching panel mount configuration, standard round actuator type, 10.49mm actuator length, circular 6.40mm diameter panel cutout, and 1/4-40 bushing thread. Both components feature solder lug termination, epoxy sealed terminals, and identical operating temperature range of -20°C to 80°C with 60,000 cycle electrical life.

The primary distinction between the main part and substitute is product status: 1571920-9 is obsolete while MTA106G is active. Secondary differences include actuator material composition (copper alloy chrome plated versus brass nickel plated), packaging format (unspecified versus bulk), and regulatory compliance status (REACH unaffected versus REACH affected, RoHS3 compliant).

Parameter Comparison

Engineering Selection Recommendations

The MTA106G substitute part is functionally and mechanically equivalent to the obsolete 1571920-9 across all critical electrical and dimensional parameters. Selection of MTA106G is appropriate for applications requiring direct replacement of the 1571920-9 in existing designs.

The MTA106G offers the advantage of active product status, ensuring ongoing availability and manufacturer support. The component is RoHS3 compliant, meeting current environmental and regulatory requirements for new production applications. The REACH affected status of MTA106G indicates compliance with European chemical regulations, whereas the 1571920-9 is REACH unaffected due to its obsolete status.

The difference in actuator material composition (brass nickel plated in MTA106G versus copper alloy chrome plated in 1571920-9) does not affect electrical performance or mechanical compatibility. Both material systems provide equivalent corrosion resistance and contact reliability within the specified operating temperature range of -20°C to 80°C.

Frequently Asked Questions (FAQ)

Q: Can MTA106G be used as a direct replacement for 1571920-9 in existing circuit designs?

A: Yes. The MTA106G maintains identical electrical specifications (SPDT circuit, 6A AC / 4A DC ratings, 125V AC / 28V DC voltage ratings, Mom-Off-Mom function) and mechanical dimensions (panel mount, 10.49mm actuator length, 6.40mm panel cutout, 1/4-40 bushing thread, solder lug termination). Direct substitution is supported without circuit modification.

Q: What is the difference in actuator material between 1571920-9 and MTA106G?

A: The 1571920-9 features a copper alloy actuator with chrome plating. The MTA106G features a brass actuator with nickel plating. Both material systems provide equivalent performance within the specified operating temperature range and do not affect electrical or mechanical compatibility.

Q: Why is the 1571920-9 classified as obsolete?

A: The 1571920-9 is no longer in active production. The MTA106G serves as the current active equivalent within the TE Connectivity ALCOSWITCH MTA Green series and is recommended for new designs and ongoing production requirements.

Q: Does MTA106G meet current regulatory compliance requirements?

A: Yes. The MTA106G is RoHS3 compliant and REACH affected, meeting current environmental and chemical regulatory standards applicable to electronic components in the European Union and other regulated markets.

Q: Are the electrical life specifications identical between 1571920-9 and MTA106G?

A: Yes. Both components are rated for 60,000 electrical cycles, providing equivalent operational longevity and reliability performance.

Q: What is the packaging difference between 1571920-9 and MTA106G?

A: The 1571920-9 packaging format is not specified in available documentation. The MTA106G is supplied in bulk packaging. Confirm packaging requirements with the component supplier for procurement planning.

Q: Are both components suitable for the same operating temperature range?

A: Yes. Both 1571920-9 and MTA106G operate across the identical temperature range of -20°C to 80°C, supporting equivalent thermal performance in field applications.
