MTA106HPC Equivalent & Substitute Parts

Part Overview

The MTA106HPC is a toggle switch manufactured by TE Connectivity ALCOSWITCH Switches, classified as a Single Pole Double Throw (SPDT) panel mount switch with a current rating of 6A AC and 4A DC. The switch features a standard round actuator with PC pin termination and is designed for on-off-momentary applications. This product is currently obsolete, making identification of equivalent substitute components necessary for ongoing maintenance, repair, and new design applications where legacy compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MTA106HPC toggle switch is determined by strict alignment of the following electrical and mechanical parameters:

Circuit Configuration: Both the main part and substitute must maintain SPDT (Single Pole Double Throw) circuit topology to preserve switching logic in the application.

Switch Function: On-Off-Mom functionality must be preserved to ensure identical operational behavior.

Mounting Type: Panel mount configuration with matching bushing thread (1/4-40) and panel cutout dimensions (Circular - 6.40mm Dia) ensures mechanical compatibility without panel modification.

Termination Style: PC pin termination must be maintained for direct PCB connection compatibility.

Actuator Type: Standard round actuator ensures consistent user interface and mechanical fit within the application enclosure.

Current and Voltage Ratings: Substitute parts must meet or exceed the AC current rating (6A) and AC voltage rating (125V) of the original component. DC ratings must support 28V operation.

Operating Temperature Range: The substitute must operate within the specified temperature envelope to ensure reliability across the intended application environment.

The E-Switch model 100SP5T1B1M2QEH qualifies as a substitute based on these criteria, with noted variations in specific electrical ratings and compliance status documented in the parameter comparison table.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The MTA106HPC is obsolete and no longer manufactured by TE Connectivity. The E-Switch 100SP5T1B1M2QEH is an active product with current manufacturing support and availability.

Compliance Status: The MTA106HPC is RoHS non-compliant, reflecting its legacy status. The 100SP5T1B1M2QEH is ROHS3 compliant, meeting current environmental and regulatory requirements for new designs and applications subject to RoHS directives.

Electrical Rating Variance: The substitute part carries a 5A AC current rating compared to the original 6A AC rating. Applications operating at or below 5A AC are directly compatible. Applications requiring the full 6A AC capacity of the original part require evaluation of actual circuit current draw to determine substitutability.

Mechanical Compatibility: Panel cutout dimensions differ by 0.05mm (6.40mm vs 6.35mm), and actuator length differs by 0.08mm. These dimensional variations are within typical manufacturing tolerances for panel mount switches and do not preclude mechanical substitution in standard applications.

Electrical Life: The original part is rated for 60,000 cycles compared to 40,000 cycles for the substitute. Applications with high cycle count requirements should account for this 33% reduction in rated electrical life.

Temperature Range: The substitute operates across a wider temperature range (-30°C to 85°C versus -20°C to 80°C), providing enhanced performance in extreme temperature environments.

Frequently Asked Questions (FAQ)

Q: Can the 100SP5T1B1M2QEH directly replace the MTA106HPC in all applications?

A: Direct substitution is possible for applications where the AC current requirement does not exceed 5A. The 100SP5T1B1M2QEH is rated for 5A AC, compared to the original 6A AC rating. Circuit current draw must be evaluated to confirm compatibility. All other electrical and mechanical parameters support direct substitution.

Q: What is the significance of the RoHS compliance difference?

A: The MTA106HPC is RoHS non-compliant, indicating it was manufactured before or outside current RoHS requirements. The 100SP5T1B1M2QEH is ROHS3 compliant, meeting current environmental regulations. For new designs or applications subject to RoHS directives, the substitute is the appropriate choice.

Q: Are the dimensional differences between the two parts significant?

A: The panel cutout diameter differs by 0.05mm (6.40mm versus 6.35mm), and the actuator length differs by 0.08mm (10.49mm versus 10.41mm). These variations fall within standard manufacturing tolerances for toggle switches and do not typically require panel modification or mechanical redesign.

Q: How does the electrical life rating difference affect component selection?

A: The MTA106HPC is rated for 60,000 electrical cycles, while the 100SP5T1B1M2QEH is rated for 40,000 cycles. Applications with cycle counts approaching or exceeding 40,000 should account for the reduced rated life of the substitute. For typical on-off applications with moderate cycle counts, this difference is not operationally significant.

Q: What is the impact of the wider operating temperature range of the substitute?

A: The 100SP5T1B1M2QEH operates from -30°C to 85°C, compared to the original -20°C to 80°C range. The substitute provides enhanced performance in cold environments (down to -30°C) and maintains operation at slightly higher temperatures (up to 85°C). This represents an improvement over the original specification.

Q: Is the DC current rating difference between the parts relevant?

A: The MTA106HPC is rated for 4A DC, while the 100SP5T1B1M2QEH is rated for 5A DC. The substitute exceeds the original DC rating, making it suitable for DC applications up to 5A at 28V. This represents an improvement over the original specification.

Q: What packaging format is available for the substitute part?

A: The 100SP5T1B1M2QEH is supplied in bulk packaging. The original MTA106HPC packaging format is not specified in the available data.
