Equivalent & Substitute Parts for 34ASP17T7M1RT Toggle Switch SPDT

Part Overview

The Grayhill Inc. 34ASP17T7M1RT is an SPDT toggle switch rated for 0.4VA at 20V with panel mount configuration and solder lug termination. This Active product features a standard round actuator with brass chrome-plated construction and non-illuminated design. The switch is suitable for low-power control applications requiring reliable on-on switching functionality across the operating temperature range of -30°C to 85°C.

Substitute parts are identified when equivalent electrical ratings, mechanical compatibility, and circuit configuration align with the original specification, enabling direct replacement in applications where component availability or procurement requirements necessitate alternative sourcing.

Key Parameters

Substitute Part Grouping Explanation

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

Mechanical Compatibility Requirements:

• Panel cutout dimensions (Circular - 11.91mm Dia)
• Bushing thread specification (15/32-32)
• Mounting type (Panel Mount)
• Termination style (Solder Lug)

Electrical Compatibility Requirements:

• Circuit configuration (SPDT)
• Switch function (On-On)
• Operating temperature range (-30°C to 85°C)

Substitution Categories:

Category 1 - Direct Electrical Equivalents (0.4VA @ 20V): Parts with identical current and voltage ratings, maintaining the same electrical performance envelope. These parts are suitable for direct replacement in applications with the original electrical specifications.

Category 2 - Higher-Rated Substitutes (5A @ 120V AC / 28V DC): Parts with elevated current and voltage ratings that exceed the original specification. These parts are mechanically and functionally compatible but operate at higher electrical capacity. Substitution is valid when the application circuit can accommodate the higher-rated component without adverse effects.

All substitute parts maintain identical mechanical interfaces, panel mounting compatibility, and SPDT on-on switching function.

Parameter Comparison

Engineering Selection Recommendations

Direct Electrical Equivalent - 7101T1ZBE (C&K):

The C&K 7101T1ZBE provides identical electrical ratings (0.4VA @ 20V AC/DC) with matching mechanical interface specifications. This part maintains the same actuator length (12.37mm) and standard round actuator type as the original 34ASP17T7M1RT. The 7101T1ZBE is ROHS3 Compliant and Active status. Electrical life is rated at 100,000 cycles, exceeding the original specification. This part is suitable for direct substitution in applications requiring equivalent electrical performance.

Higher-Rated Substitutes - 100SP1T8B13M1QEH (E-Switch), 7101T2PZQE (C&K), 7101TZQE (C&K):

These three parts provide elevated electrical ratings (5A @ 120V AC / 28V DC) while maintaining identical mechanical compatibility through matching panel cutout dimensions and bushing thread specifications. All three parts are SPDT on-on configuration with solder lug termination and Active product status.

• 100SP1T8B13M1QEH features a standard round actuator with 18.00mm length and ROHS3 Compliance.
• 7101T2PZQE features a flat anti-rotation actuator with 15.49mm length and ROHS3 Compliance.
• 7101TZQE features a standard round actuator with 17.45mm length and ROHS3 Compliance.

Higher-rated substitutes are applicable when the application circuit design permits operation at elevated electrical capacity without functional degradation. Actuator length variation must be evaluated against panel geometry and user interface requirements.

All substitute parts maintain Active product status and environmental compliance certifications suitable for continued procurement and deployment.

Frequently Asked Questions (FAQ)

Q: Can the 7101T1ZBE directly replace the 34ASP17T7M1RT in my application?

A: Yes. The 7101T1ZBE provides identical electrical ratings (0.4VA @ 20V AC/DC), matching mechanical interface (11.91mm panel cutout, 15/32-32 bushing thread), identical actuator length (12.37mm), and equivalent SPDT on-on switching function. Both parts operate across -30°C to 85°C. The 7101T1ZBE is suitable for direct substitution.

Q: What is the difference between the direct equivalent and higher-rated substitutes?

A: The 7101T1ZBE maintains the original 0.4VA @ 20V electrical specification. The 100SP1T8B13M1QEH, 7101T2PZQE, and 7101TZQE provide higher electrical capacity (5A @ 120V AC / 28V DC). All four parts share identical mechanical interfaces and SPDT on-on function. Higher-rated parts are substitutable when circuit design accommodates elevated electrical ratings.

Q: Do actuator length differences affect mechanical compatibility?

A: Actuator length variations must be evaluated against panel geometry and user interface design. The original 34ASP17T7M1RT has 12.37mm actuator length. The 7101T1ZBE matches this length exactly. Higher-rated substitutes have longer actuators (15.49mm to 18.00mm). Panel cutout dimensions and bushing thread remain identical across all parts. Verify actuator protrusion clearance in your specific panel assembly.

Q: Are all substitute parts RoHS compliant?

A: The original 34ASP17T7M1RT is RoHS Compliant. All four substitute parts are ROHS3 Compliant, which represents an updated RoHS standard. ROHS3 Compliance is compatible with RoHS Compliant applications.

Q: What is the electrical life difference between the original and substitutes?

A: The 34ASP17T7M1RT is rated for 40,000 electrical cycles. The 7101T1ZBE, 7101T2PZQE, and 7101TZQE are each rated for 100,000 electrical cycles. The 100SP1T8B13M1QEH matches the original 40,000 cycle rating. Higher electrical life ratings provide extended operational durability.

Q: Can I use a higher-rated substitute in a low-power application?

A: Yes. Higher-rated parts (5A @ 120V) are mechanically and functionally compatible with applications designed for lower ratings (0.4VA @ 20V). The higher electrical capacity does not create incompatibility in lower-power circuits. Mechanical interface compatibility and SPDT on-on function remain the determining factors for substitution validity.

Q: What packaging options are available?

A: The original 34ASP17T7M1RT is supplied in standard packaging. Substitute parts are available in Bulk (7101T1ZBE, 100SP1T8B13M1QEH, 7101TZQE) or Tray (7101T2PZQE) packaging. Packaging selection depends on procurement volume and handling requirements.

Q: Are all parts suitable for solder lug termination in my PCB assembly?

A: Yes. All substitute parts feature solder lug termination matching the original 34ASP17T7M1RT specification. Solder lug compatibility is consistent across all listed parts.
