Equivalent & Substitute Parts for 34ASP12B1M1RT

Part Overview

The 34ASP12B1M1RT is an SPDT toggle switch manufactured by Grayhill Inc., rated for 0.4VA at 20V AC/DC. This panel-mount switch features a standard round actuator with solder lug termination and operates across -30°C to 85°C. The product is Active status and ROHS3 compliant with unlimited moisture sensitivity rating.

Substitute parts are identified when equivalent electrical ratings, mechanical interfaces, and circuit configurations are available from alternative manufacturers. This ensures design flexibility and supply chain continuity while maintaining functional compatibility within specified operating parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 34ASP12B1M1RT is determined by the following critical parameters:

Mandatory Matching Criteria:

• Circuit configuration: SPDT
• Switch function: On-On
• Mounting type: Panel Mount
• Panel cutout dimensions: Circular 6.35mm diameter
• Bushing thread: 1/4-40
• Termination style: Solder Lug
• Operating temperature range: -30°C ~ 85°C

Electrical Compatibility Criteria:

• Current rating must equal or exceed 0.4VA
• Voltage rating (AC and DC) must equal or exceed 20V

Compliance Criteria:

• RoHS3 compliance required
• MSL rating of 1 (Unlimited) preferred

Two substitute parts meet these criteria with varying electrical performance levels and feature sets.

Engineering Selection Recommendations

100SP1T2B3M1QEH (E-Switch) - Higher Power Rating Substitute

This substitute provides elevated electrical performance with 5A current capacity and 120V AC rating, exceeding the 34ASP12B1M1RT specifications. Mechanical and thermal compatibility is maintained through identical panel cutout dimensions, bushing thread, and operating temperature range. The part is ROHS3 compliant with MSL 1 rating. Selection of this substitute is appropriate when circuit requirements demand higher current handling or voltage margins. Epoxy sealed terminals provide enhanced environmental protection.

7101P4YZBE22 (C&K) - Equivalent Rating Substitute

This substitute maintains electrical parity with the 34ASP12B1M1RT at 0.4VA and 20V ratings while offering extended electrical life of 100,000 cycles versus 40,000 cycles. Mechanical interfaces are identical. ROHS3 compliance is confirmed. The actuator design differs (flat anti-rotation versus standard round) and actuator length is 6.35mm versus 5.08mm. This substitute is suitable for applications requiring extended cycle life within equivalent electrical parameters. Packaging is supplied in Tray format rather than Bulk.

Both substitutes maintain Active product status and full regulatory compliance. Selection depends on electrical performance requirements and mechanical actuator preferences.

Frequently Asked Questions (FAQ)

Q: Can the 100SP1T2B3M1QEH be used in place of the 34ASP12B1M1RT?

A: Yes. The 100SP1T2B3M1QEH maintains identical mechanical interfaces (panel cutout, bushing thread, termination) and circuit configuration (SPDT On-On). Its electrical ratings of 5A and 120V AC exceed the 34ASP12B1M1RT requirements of 0.4VA and 20V, providing operational margin. Both parts are ROHS3 compliant and operate across -30°C to 85°C.

Q: What is the difference between the 7101P4YZBE22 and the 34ASP12B1M1RT?

A: Electrical ratings are equivalent (0.4VA, 20V AC/DC). The 7101P4YZBE22 offers extended electrical life of 100,000 cycles compared to 40,000 cycles. The actuator design differs: the 7101P4YZBE22 features a flat anti-rotation actuator at 6.35mm length, while the 34ASP12B1M1RT uses a standard round actuator at 5.08mm length. Packaging differs (Tray versus Bulk). Mechanical panel interfaces remain identical.

Q: Are there packaging differences between these substitutes?

A: Yes. The 34ASP12B1M1RT and 100SP1T2B3M1QEH are supplied in Bulk packaging. The 7101P4YZBE22 is supplied in Tray packaging. This affects handling and storage but does not impact electrical or mechanical compatibility.

Q: Do all three parts meet RoHS compliance?

A: Yes. The 34ASP12B1M1RT, 100SP1T2B3M1QEH, and 7101P4YZBE22 are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: Which substitute should be selected for maximum cycle life?

A: The 7101P4YZBE22 provides 100,000 electrical cycles compared to 40,000 cycles for the 34ASP12B1M1RT. This extended life is achieved within equivalent electrical ratings.

Q: Can the 34ASP12B1M1RT be used in high-voltage applications?

A: No. The 34ASP12B1M1RT is rated for 20V maximum. For applications requiring 120V AC operation, the 100SP1T2B3M1QEH is the appropriate substitute with its 120V AC rating.
