MTA206T Equivalent & Substitute Parts

Part Overview

The MTA206T is a toggle switch manufactured by TE Connectivity ALCOSWITCH Switches, classified as a DPDT (Double Pole Double Throw) panel mount switch with a current rating of 6A AC and 4A DC. The switch features a standard round actuator, solder lug termination, and epoxy sealed terminals for environmental protection. The product is currently obsolete, which necessitates identification of equivalent substitute components that maintain functional compatibility for existing applications and new designs requiring equivalent switching capability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MTA206T is determined by strict alignment of the following critical parameters:

Circuit and Function Compatibility: The substitute part must maintain DPDT circuit configuration with On-Off-Mom switching function to preserve electrical behavior in the application.

Electrical Ratings: The substitute must support equivalent or higher current and voltage ratings. The MTA206T operates at 6A AC/125V and 4A DC/28V. Substitute parts must meet or exceed these specifications to ensure safe operation without derating.

Mechanical Interface: Panel mount configuration, standard round actuator type, solder lug termination, and 1/4-40 bushing thread are mandatory for physical compatibility with existing panel cutouts and circuit board layouts.

Environmental Sealing: Epoxy sealed terminals are required to maintain protection equivalent to the original component.

Dimensional Compatibility: Panel cutout diameter and actuator length must be within acceptable tolerances to ensure proper fit and operation.

The substitute part 100DP5T1B1M1QEH from E-Switch meets these criteria with equivalent DPDT configuration, compatible mechanical interface, and electrical ratings within acceptable parameters for this application category.

Engineering Selection Recommendations

Product Status Consideration: The MTA206T is obsolete and no longer manufactured by TE Connectivity. The 100DP5T1B1M1QEH is an active product from E-Switch with current manufacturing support and availability.

Compliance and Certification: The 100DP5T1B1M1QEH is ROHS3 compliant, meeting current regulatory requirements for electronic components. The original MTA206T is RoHS non-compliant, reflecting its legacy status. For new designs or applications subject to RoHS requirements, the E-Switch substitute is the appropriate selection.

Electrical Rating Differences: The substitute part is rated at 5A AC/120V compared to the original 6A AC/125V. Applications operating at or below 5A AC and 120V AC are directly compatible. Applications requiring the full 6A AC rating of the original component require evaluation of actual circuit current draw to determine if the 5A rating of the substitute is acceptable.

Electrical Life: The original component specifies 60,000 cycles while the substitute specifies 40,000 cycles. Applications with high cycle count requirements should account for this difference in component selection and maintenance planning.

Mechanical and Functional Compatibility: All mechanical parameters including panel cutout dimensions, bushing thread, actuator type, and termination style are compatible between the two components. Direct physical substitution is feasible without panel modification.

Frequently Asked Questions (FAQ)

Q: Can the 100DP5T1B1M1QEH directly replace the MTA206T in existing applications?

A: Direct physical replacement is possible due to compatible panel mount configuration, 1/4-40 bushing thread, and solder lug termination. Electrical compatibility depends on application current requirements. If the application draws 5A AC or less at 120V AC, the substitute is fully compatible. Applications requiring the full 6A AC rating require current draw verification.

Q: What is the significance of the lower electrical life rating (40,000 cycles vs. 60,000 cycles)?

A: The substitute part is rated for 40,000 electrical cycles compared to the original 60,000 cycles. For applications with frequent switching operations, this difference may impact component replacement intervals. Applications with lower cycle counts are unaffected by this specification difference.

Q: Why is RoHS compliance important for this substitution?

A: The original MTA206T is RoHS non-compliant, reflecting its legacy design. The substitute 100DP5T1B1M1QEH is ROHS3 compliant, meeting current environmental and regulatory standards. For new equipment designs, applications subject to RoHS requirements, or procurement policies requiring RoHS compliance, the substitute is the appropriate selection.

Q: Are the panel cutout dimensions identical between the two parts?

A: The panel cutout diameters differ by 0.05mm (MTA206T: 6.40mm vs. 100DP5T1B1M1QEH: 6.35mm). This difference is within standard mechanical tolerances for panel cutout drilling and does not require panel modification for substitution.

Q: What is the difference in operating temperature range?

A: The substitute part operates across a wider temperature range (-30°C to 85°C) compared to the original (-20°C to 80°C). This provides additional margin for applications in temperature-variable environments.

Q: Is the actuator length difference significant?

A: The actuator length differs by 0.08mm (MTA206T: 10.49mm vs. 100DP5T1B1M1QEH: 10.41mm). This difference is negligible for standard panel mount applications and does not affect operational compatibility.

Q: What packaging is available for the substitute part?

A: The 100DP5T1B1M1QEH is available in bulk packaging, compared to the original component's standard packaging. Procurement quantities and packaging requirements should be confirmed with the supplier.
