Toggle Switch DPDT 34CMDP11B2M6RT Equivalent & Substitute Parts

Part Overview

The 34CMDP11B2M6RT is a toggle switch manufactured by Grayhill Inc., classified as a DPDT (Double Pole Double Throw) through-hole, right-angle mounted component. This switch operates at 0.4VA with voltage ratings of 20V AC/DC and features epoxy sealed terminals with a non-illuminated standard round actuator. The product is currently active in production with 762 units in stock.

Alternative equivalent parts are necessary when the primary component experiences supply constraints, extended lead times, or when design requirements permit substitution within the defined electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 34CMDP11B2M6RT is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Circuit configuration: DPDT
• Switch function: On-On
• Current rating: 0.4VA (AC/DC)
• Voltage rating: 20V AC and 20V DC
• Mounting type: Through Hole, Right Angle
• Termination style: PC Pin
• Actuator type: Standard Round
• Operating temperature range: -30°C to 85°C minimum

Allowable Variations:

• Actuator length (9.40mm primary vs. alternative dimensions)
• Electrical life cycle rating (30,000 cycles primary vs. higher ratings in substitutes)
• Ingress protection rating (additional protection in substitutes acceptable)
• Manufacturer identity and series designation

The substitute part ET21MD1ABE from C&K meets all mandatory matching parameters and qualifies as a direct electrical and mechanical equivalent.

Engineering Selection Recommendations

Primary Part: 34CMDP11B2M6RT

Selection criteria: Use when Grayhill Inc. supply chain is preferred, when the 9.40mm actuator length is specifically required for mechanical fit, or when the 30,000-cycle electrical life rating is sufficient for the application.

Substitute Part: ET21MD1ABE

Selection criteria: Use when C&K component availability is advantageous, when the 6.10mm actuator length accommodates the mechanical design, or when extended electrical life (60,000 cycles) provides additional operational margin. The IP57 ingress protection rating offers enhanced environmental sealing compared to the primary part.

Both parts maintain identical electrical performance across voltage, current, and circuit configuration parameters. Both are ROHS3 compliant with EAR99 export classification and unlimited moisture sensitivity rating. Selection between these parts is based on supply availability, mechanical fit requirements, and environmental protection needs rather than electrical performance differences.

Frequently Asked Questions (FAQ)

Q: Can ET21MD1ABE replace 34CMDP11B2M6RT in all applications?

A: ET21MD1ABE qualifies as an electrical and mechanical equivalent. The primary difference is actuator length (6.10mm vs. 9.40mm). Verify that the shorter actuator length accommodates your panel cutout and mechanical assembly before substitution.

Q: What is the significance of the different electrical life ratings?

A: The primary part (34CMDP11B2M6RT) is rated for 30,000 cycles, while the substitute (ET21MD1ABE) is rated for 60,000 cycles. Both ratings are based on manufacturer testing. Select based on your application's expected cycle count over the product lifetime.

Q: Does the IP57 rating on ET21MD1ABE affect compatibility?

A: No. The IP57 ingress protection rating on ET21MD1ABE represents enhanced environmental sealing. This additional protection does not create incompatibility; it provides superior performance in dusty or wet environments compared to the primary part.

Q: Are there any compliance differences between these parts?

A: Both parts are ROHS3 compliant, carry EAR99 export classification, and share identical HTSUS codes (8536.50.9065). The ET21MD1ABE is REACH Affected while the primary part is REACH Unaffected. Verify REACH compliance requirements for your specific application and region.

Q: What is the impact of different actuator lengths on PCB layout?

A: Actuator length affects the vertical clearance required above the PCB. The 34CMDP11B2M6RT requires 9.40mm clearance, while ET21MD1ABE requires 6.10mm. Verify your mechanical design accommodates the substitute's dimensions before implementation.

Q: Can these parts be used interchangeably in existing designs?

A: Electrical interchangeability is confirmed. Mechanical interchangeability depends on panel cutout dimensions and actuator clearance. Conduct mechanical verification before substituting in production designs.
