Equivalent & Substitute Parts for 34DWMSP42B4M7RT

Part Overview

The 34DWMSP42B4M7RT is an SPDT toggle switch manufactured by Grayhill Inc., designed for through-hole, right-angle vertical mounting applications. This switch operates at 0.4VA with voltage ratings of 20V AC/DC and features momentary-off-momentary (Mom-Off-Mom) switching functionality. The component is classified as Active product status with full RoHS3 compliance and REACH unaffected designation. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling direct functional replacement in circuit designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 34DWMSP42B4M7RT is determined by strict alignment of the following critical parameters:

Electrical Equivalence Requirements:

• Circuit configuration must be SPDT
• Switch function must be Mom-Off-Mom
• Current rating must be 0.4VA (AC/DC)
• Voltage ratings must be 20V AC and 20V DC minimum

Mechanical Equivalence Requirements:

• Mounting type must be Through Hole, Right Angle, Vertical
• Actuator type must be Standard Round
• Termination style must be PC Pin
• Operating temperature range must encompass -30°C to 85°C

Environmental & Compliance Requirements:

• Electrical life must be 30,000 cycles minimum
• RoHS3 compliance required
• Moisture Sensitivity Level must be 1 (Unlimited)

The substitute part T105MH9AVBE from C&K satisfies all electrical and mechanical equivalence criteria, with the exception of ingress protection specification variance and REACH status difference. These differences do not affect functional substitution in applications where the original IP67 rating is not a design requirement.

Engineering Selection Recommendations

Primary Selection (34DWMSP42B4M7RT - Grayhill Inc.): Select the original Grayhill part when IP67 ingress protection is a design requirement or when REACH unaffected status is mandated by supply chain compliance protocols. This part maintains Active product status with established manufacturing continuity.

Substitute Selection (T105MH9AVBE - C&K): The C&K T105MH9AVBE toggle switch functions as an electrical and mechanical equivalent for applications where IP67 rating is not specified as a design requirement. This substitute maintains ROHS3 compliance and identical electrical performance characteristics. The actuator length variation (5.33mm versus 6.10mm) requires mechanical clearance verification in panel-mounted applications. REACH affected status requires evaluation against supply chain documentation requirements.

Both parts maintain Active product status, ensuring continued manufacturing availability and supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can T105MH9AVBE replace 34DWMSP42B4M7RT in all applications?

A: Functional electrical replacement is supported for applications where IP67 ingress protection is not a design specification. The 0.77mm actuator length difference requires verification of mechanical clearance in the panel cutout and actuator travel space.

Q: What is the significance of the actuator length difference?

A: The 34DWMSP42B4M7RT features a 6.10mm actuator length while the T105MH9AVBE has a 5.33mm actuator length. This 0.77mm variation may affect tactile feedback characteristics and panel mounting geometry. Mechanical fit verification is required before substitution.

Q: Are both parts RoHS3 compliant?

A: Yes, both 34DWMSP42B4M7RT and T105MH9AVBE are ROHS3 compliant. However, the C&K part carries REACH affected status while the Grayhill part is REACH unaffected. Supply chain compliance requirements must be evaluated.

Q: What is the difference between IP67 and unspecified ingress protection?

A: The 34DWMSP42B4M7RT is rated IP67 (dust tight and waterproof to 1 meter for 30 minutes). The T105MH9AVBE does not specify an ingress protection rating. Applications requiring environmental sealing must retain the original Grayhill part.

Q: Do both switches support the same electrical life?

A: Yes, both parts are rated for 30,000 electrical cycles, ensuring equivalent operational longevity in Mom-Off-Mom switching applications.

Q: What packaging differences exist between these parts?

A: The 34DWMSP42B4M7RT is supplied in Bulk packaging, while the T105MH9AVBE is supplied in Tray packaging. Inventory management and handling procedures may differ accordingly.
