C&K 7101MPYZBE Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The C&K 7101MPYZBE is an active-status toggle switch with SPDT (Single Pole Double Throw) circuit configuration, rated for 0.4VA at 20V AC/DC. This panel-mount switch features anti-rotation actuator design with epoxy-sealed solder lug termination, suitable for applications requiring reliable switching in the 20V operating range. Substitute parts are identified for applications where higher voltage or current ratings are required, or where alternative manufacturer sourcing is necessary.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the C&K 7101MPYZBE are qualified based on the following substitution criteria:

Mechanical Compatibility:

• Panel mount configuration with identical panel cutout dimensions (Circular - 6.35mm Dia)
• Matching bushing thread specification (1/4-40)
• Identical actuator length (5.08mm)
• Solder lug termination style

Electrical Compatibility:

• SPDT circuit configuration with On-On switch function
• Operating temperature range of -30°C ~ 85°C or broader
• Epoxy-sealed terminal construction

Compliance Requirements:

• ROHS3 compliance maintained
• EAR99 ECCN classification
• HTSUS code 8536.50.9065

The E-Switch 100SP1T2B1M1QEH and 100SP1T2B3M1QEH parts meet these mechanical and electrical compatibility criteria. These substitutes provide higher current ratings (5A) and voltage ratings (120V AC / 28V DC) compared to the original part, making them suitable for applications requiring increased electrical capacity within the same mechanical footprint.

Parameter Comparison

Engineering Selection Recommendations

C&K 7101MPYZBE Selection Criteria:

• Applications operating at 20V AC/DC with current requirements up to 0.4VA
• Extended electrical life requirement (100,000 cycles)
• Anti-rotation actuator requirement for specific mounting applications
• REACH-affected component sourcing acceptable

E-Switch 100SP1T2B1M1QEH / 100SP1T2B3M1QEH Selection Criteria:

• Applications requiring higher voltage ratings (120V AC / 28V DC)
• Higher current capacity (5A AC/DC)
• REACH-unaffected component sourcing requirement
• Mechanical footprint compatibility with existing panel designs
• Standard round actuator configuration acceptable

Both substitute parts maintain ROHS3 compliance and EAR99 classification. The primary trade-off between the C&K original and E-Switch substitutes is electrical life rating: the original part provides 100,000 cycles versus 40,000 cycles for the substitutes. Component selection should be based on specific application voltage, current, and cycle-life requirements.

Frequently Asked Questions (FAQ)

Q: Can the E-Switch 100SP1T2B1M1QEH or 100SP1T2B3M1QEH be used as direct replacements for the C&K 7101MPYZBE?

A: These parts are mechanically compatible due to identical panel cutout dimensions (6.35mm circular), bushing thread (1/4-40), and actuator length (5.08mm). Both maintain SPDT On-On configuration with solder lug termination. However, the E-Switch parts provide higher electrical ratings (5A at 120V AC / 28V DC) compared to the original (0.4VA at 20V). Substitution is appropriate only when the application voltage and current requirements are within the E-Switch specifications.

Q: What are the key differences between the C&K 7101MPYZBE and E-Switch substitutes?

A: The primary differences are: (1) Current rating: 0.4VA versus 5A; (2) AC voltage rating: 20V versus 120V; (3) DC voltage rating: 20V versus 28V; (4) Electrical life: 100,000 cycles versus 40,000 cycles; (5) Actuator type: anti-rotation versus standard round; (6) REACH status: affected versus unaffected.

Q: Are the E-Switch 100SP1T2B1M1QEH and 100SP1T2B3M1QEH interchangeable with each other?

A: Yes. Both parts share identical electrical specifications (5A at 120V AC / 28V DC), mechanical dimensions, and termination style. The primary difference is inventory availability (832 pcs versus 5890 pcs).

Q: What compliance certifications apply to these parts?

A: All three parts are ROHS3 compliant and classified as EAR99 for export control purposes. The C&K 7101MPYZBE is REACH-affected, while the E-Switch substitutes are REACH-unaffected.

Q: Does the difference in electrical life (100,000 versus 40,000 cycles) affect substitution suitability?

A: Electrical life rating should be evaluated against specific application duty cycle requirements. Applications with cycle counts exceeding 40,000 cycles should retain the C&K original part. Applications with lower cycle requirements can use E-Switch substitutes.
