Equivalent & Substitute Parts for 34ASP47T7M1QT Toggle Switch SPDT

Part Overview

The 34ASP47T7M1QT is an active-status toggle switch manufactured by Grayhill Inc., configured as a Single Pole Double Throw (SPDT) momentary-off-momentary (Mom-Off-Mom) switch. This panel-mount component is rated for 5A at 125V AC and 28V DC, with a non-illuminated brass chrome-plated actuator. The part is ROHS3 compliant and maintains an electrical life of 40,000 cycles. Substitute parts are identified when equivalent electrical ratings, mechanical mounting specifications, and circuit configurations are available from alternative manufacturers, enabling procurement flexibility and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 34ASP47T7M1QT are identified based on strict electrical and mechanical compatibility criteria. The following parameters must align for substitution eligibility:

Critical Matching Parameters:

• Circuit configuration: SPDT
• Switch function: Mom-Off-Mom
• Current rating: 5A (AC/DC)
• Mounting type: Panel Mount
• Panel cutout dimensions: Circular - 11.91mm Dia
• Bushing thread: 15/32-32
• Termination style: Solder Lug
• Operating temperature range: -30°C ~ 85°C
• Electrical life: 40,000 Cycles

Allowable Variation Parameters:

• Voltage rating - AC: 120V to 125V (within operational tolerance)
• Voltage rating - DC: 28V (fixed requirement)
• Actuator length: Variation permitted within mechanical envelope
• Ingress protection: Enhanced ratings acceptable
• Additional features: Epoxy sealed terminals acceptable

The C&K 7105TCWZQE and 7105TZQE meet all critical matching parameters and operate within the specified electrical and mechanical constraints of the 34ASP47T7M1QT application space.

Parameter Comparison

Engineering Selection Recommendations

34ASP47T7M1QT (Grayhill Inc.) - Primary specification. Active product status with ROHS3 compliance and REACH unaffected status. Suitable for applications requiring standard environmental protection without enhanced sealing requirements.

7105TCWZQE (C&K) - Functionally equivalent substitute. Active product status with ROHS3 compliance. REACH affected status requires compliance verification in regulated markets. Provides enhanced IP67 ingress protection and epoxy sealed terminals for applications requiring moisture and dust resistance. Actuator length of 17.45mm versus 12.37mm requires panel envelope clearance verification.

7105TZQE (C&K) - Functionally equivalent substitute. Active product status with ROHS3 compliance. REACH affected status requires compliance verification in regulated markets. Provides epoxy sealed terminals without specified ingress protection rating. Actuator length of 17.45mm versus 12.37mm requires panel envelope clearance verification.

Selection between these parts depends on environmental exposure requirements, panel depth constraints, and regulatory compliance obligations in the end-use market.

Frequently Asked Questions (FAQ)

Q: Can the 7105TCWZQE or 7105TZQE be used as direct replacements for the 34ASP47T7M1QT?

A: Yes, both C&K parts meet the critical electrical and mechanical specifications: SPDT circuit, Mom-Off-Mom function, 5A rating at 125V AC / 28V DC, panel mount configuration with identical cutout and thread specifications, solder lug termination, and 40,000-cycle electrical life. The primary consideration is actuator length: the C&K parts measure 17.45mm versus the Grayhill 12.37mm, requiring verification that panel depth accommodates the longer actuator.

Q: What is the difference between the 7105TCWZQE and 7105TZQE?

A: Both parts are electrically and mechanically identical. The 7105TCWZQE includes IP67 ingress protection (dust tight, waterproof), while the 7105TZQE does not specify an ingress protection rating. Both include epoxy sealed terminals. Selection depends on environmental exposure requirements.

Q: Are there voltage compatibility concerns with the 120V AC rating on the C&K substitutes versus the 125V AC rating on the Grayhill part?

A: No. The 120V AC rating on the C&K parts is within the operational tolerance for applications designed for 125V AC. The parts are electrically compatible for this voltage range.

Q: What compliance considerations apply to the C&K substitute parts?

A: Both 7105TCWZQE and 7105TZQE are ROHS3 compliant. However, both carry REACH affected status, whereas the 34ASP47T7M1QT is REACH unaffected. Applications subject to REACH regulations require compliance verification before substitution.

Q: Does the longer actuator on the C&K parts affect electrical performance?

A: No. Actuator length is a mechanical dimension that does not affect electrical performance, circuit function, or electrical ratings. The longer actuator (17.45mm versus 12.37mm) is a mechanical consideration only, requiring panel envelope clearance verification.

Q: Are all three parts suitable for the same operating temperature range?

A: Yes. All three parts operate across -30°C to 85°C, ensuring thermal compatibility across the specified range.
