MTF226N Equivalent & Substitute Parts

Part Overview

The MTF226N is a toggle switch manufactured by TE Connectivity ALCOSWITCH Switches, classified as a DPDT (Double Pole Double Throw) panel mount switch with a rated capacity of 6A at 125V AC and 4A at 28V DC. The switch features a flatted brass nickel-plated actuator with a 12.32mm length and non-illuminated design. This product is currently obsolete, making identification of equivalent substitute parts essential for system maintenance, repair, and component replacement in legacy applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MTF226N requires evaluation of electrical and mechanical compatibility based on the following critical parameters:

Electrical Compatibility Criteria:

• Circuit configuration must be DPDT
• Switch function must be On-On
• Current and voltage ratings must meet or exceed application requirements
• Termination style must be Solder Lug for circuit board integration

Mechanical Compatibility Criteria:

• Mounting type must be Panel Mount
• Panel cutout diameter must accommodate the 6.40mm circular opening
• Bushing thread must be 1/4-40 for panel fastening
• Actuator length must be compatible with panel thickness and operational clearance

Environmental and Operational Criteria:

• Operating temperature range must encompass the application environment
• Electrical life rating must support the intended duty cycle

The substitute part 100DP1T6B11M1REH from E-Switch shares the same circuit configuration (DPDT), switch function (On-On), mounting type (Panel Mount), termination style (Solder Lug), panel cutout dimensions (6.35mm circular), bushing thread (1/4-40), and actuator length (12.30mm). However, electrical ratings differ significantly, requiring application-specific evaluation.

Parameter Comparison

Engineering Selection Recommendations

The 100DP1T6B11M1REH from E-Switch provides mechanical and functional compatibility with the MTF226N in terms of circuit configuration, mounting interface, and actuator dimensions. However, electrical rating differences are substantial and must be evaluated against specific application requirements.

Electrical Considerations: The MTF226N is rated for 6A at 125V AC, while the 100DP1T6B11M1REH is rated for 0.4VA at 20V AC/DC. The substitute part operates at significantly lower power levels and voltage ratings. Selection of the 100DP1T6B11M1REH is appropriate only for applications where the actual operating current and voltage remain within its specified limits.

Compliance and Product Status: The MTF226N is obsolete and RoHS non-compliant. The 100DP1T6B11M1REH is an active product with RoHS3 compliance, making it suitable for new designs and applications subject to RoHS regulations. Both parts are REACH Unaffected and classified as EAR99.

Operational Life: The MTF226N provides 80,000 electrical cycles, while the 100DP1T6B11M1REH provides 40,000 cycles. Applications requiring extended operational life should account for this difference in cycle rating.

Temperature Range: The 100DP1T6B11M1REH operates across a wider temperature range (-30°C to 85°C) compared to the MTF226N (-20°C to 80°C), providing greater environmental flexibility.

Frequently Asked Questions (FAQ)

Q: Can the 100DP1T6B11M1REH directly replace the MTF226N in all applications?

A: Direct replacement is limited to applications where the operating current and voltage remain within the 100DP1T6B11M1REH specifications (0.4VA at 20V AC/DC). The substitute part cannot support the full 6A at 125V AC rating of the original MTF226N. Application-specific electrical requirements must be evaluated before substitution.

Q: What are the mechanical compatibility factors between these two parts?

A: Both parts share identical mounting configurations: Panel Mount type, 1/4-40 bushing thread, Solder Lug termination, and nearly identical actuator lengths (12.32mm vs. 12.30mm). Panel cutout diameters are also compatible (6.40mm vs. 6.35mm). Mechanical installation is compatible without modification.

Q: How do the electrical life ratings compare?

A: The MTF226N provides 80,000 electrical cycles, while the 100DP1T6B11M1REH provides 40,000 cycles. For applications with high switching frequency or extended operational life requirements, the reduced cycle rating of the substitute part must be considered in system design.

Q: Are there compliance differences between the MTF226N and 100DP1T6B11M1REH?

A: Yes. The MTF226N is RoHS non-compliant and obsolete. The 100DP1T6B11M1REH is RoHS3 compliant and an active product. For applications subject to RoHS regulations or requiring long-term component availability, the 100DP1T6B11M1REH is the appropriate choice.

Q: What is the impact of the different actuator types?

A: The MTF226N features a flatted actuator, while the 100DP1T6B11M1REH features a flat anti-rotation actuator. The anti-rotation design of the substitute part provides additional mechanical stability. Both actuator types are compatible with standard panel-mount toggle switch installations.

Q: How should voltage and current ratings be evaluated for substitution?

A: The application's actual operating voltage and current must be compared against the substitute part's ratings. The 100DP1T6B11M1REH is suitable only for applications operating at 20V or below with current draw not exceeding 0.4VA. Applications requiring the full 125V AC or 6A capacity of the MTF226N cannot use this substitute.
