Engineering Selection Recommendations
The MTA106F is the direct equivalent substitute for the obsolete 1571920-7. Both components are manufactured by TE Connectivity ALCOSWITCH and belong to the MTA Green series. All electrical specifications, mechanical dimensions, and environmental operating parameters are identical.
Selection Basis:
The MTA106F is recommended for new designs and production applications because it maintains active product status with TE Connectivity. The substitute part carries ROHS3 compliance certification and REACH regulatory status, providing assurance of ongoing manufacturing support and regulatory alignment with current environmental standards.
Both parts share identical electrical ratings (6A AC / 4A DC), mechanical mounting specifications (panel mount with 1/4-40 bushing thread and 6.40mm circular cutout), and operational characteristics (60,000 cycle electrical life, -20°C to 80°C operating range).
The only material difference between the parts is the actuator material composition: the main part uses Copper Alloy with Chrome Plating, while the substitute uses Brass with Nickel Plating. This material variation does not affect electrical or mechanical performance within the specified operating parameters.
Frequently Asked Questions (FAQ)
Q: Can MTA106F be used as a direct replacement for 1571920-7 in existing designs?
A: Yes. The MTA106F is electrically and mechanically equivalent to the 1571920-7. All electrical ratings, circuit configuration, mounting dimensions, and termination specifications are identical. The component can be substituted without circuit redesign or panel modification.
Q: What is the primary reason for substitution?
A: The 1571920-7 is classified as obsolete. The MTA106F is the active equivalent from the same manufacturer and series, ensuring continued component availability and manufacturing support.
Q: Are there differences in compliance certifications between the two parts?
A: Yes. The MTA106F carries ROHS3 compliance and REACH regulatory status, while the 1571920-7 is listed as REACH Unaffected. For applications requiring regulatory compliance documentation, the MTA106F provides current certification status.
Q: Do the actuator material differences affect performance?
A: No. The actuator material difference (Copper Alloy Chrome Plated versus Brass Nickel Plated) does not affect electrical performance, switching characteristics, or mechanical operation within the specified operating parameters of -20°C to 80°C and 60,000 electrical cycles.
Q: What are the packaging differences?
A: The 1571920-7 is supplied with packaging designation "-" (not specified), while the MTA106F is supplied in Bulk packaging. Both parts are identical in form, fit, and function.
