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

Part Overview

The C&K 7101MPHZQE is an active-status toggle switch with SPDT (Single Pole Double Throw) circuit configuration, rated for 5A at 120V AC and 28V DC. This panel-mount switch features an anti-rotation brass actuator with epoxy-sealed solder lug terminals and operates across -30°C to 85°C. The part maintains ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when inventory requirements necessitate qualified alternatives.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 7101MPHZQE are qualified based on electrical and mechanical parameter equivalence. The following parameters determine substitution eligibility:

Critical Matching Parameters:

• Circuit configuration: SPDT
• Switch function: On-On
• Current rating: 5A (AC/DC)
• Voltage ratings: 120V AC / 28V DC
• Mounting type: Panel Mount
• Termination style: Solder Lug
• Panel cutout dimensions: Circular - 6.35mm Dia
• Bushing thread: 1/4-40
• Operating temperature range: -30°C to 85°C
• Features: Epoxy sealed terminals

The E-Switch 100 series parts (100SP1T2B5M1QEH and 100SP1T2B9M1QEH) meet all critical electrical and mechanical parameters. Differences in actuator type (standard round vs. anti-rotation) and electrical life cycles do not affect functional substitution for applications within the specified electrical and environmental parameters.

Parameter Comparison

Engineering Selection Recommendations

Both E-Switch substitute parts maintain active product status and ROHS3 compliance, ensuring regulatory alignment with the primary C&K part. The 100SP1T2B5M1QEH and 100SP1T2B9M1QEH are electrically and mechanically equivalent for panel-mount SPDT toggle switch applications operating within 5A at 120V AC / 28V DC specifications.

Selection between substitute parts should be based on application-specific requirements regarding actuator geometry. The C&K 7101MPHZQE features an anti-rotation actuator design, while E-Switch alternatives employ standard round actuators. Both designs accommodate the identical 6.35mm circular panel cutout and 1/4-40 bushing thread, ensuring mechanical interchangeability in standard panel installations.

The reduced electrical life specification of E-Switch parts (40,000 cycles versus 100,000 cycles) does not affect substitution eligibility for applications within the stated electrical and environmental parameters. All three parts carry identical moisture sensitivity and temperature operating ranges.

Frequently Asked Questions (FAQ)

Q: Can the E-Switch 100SP1T2B5M1QEH or 100SP1T2B9M1QEH directly replace the C&K 7101MPHZQE in existing designs?

A: Yes. Both E-Switch parts are mechanically and electrically equivalent. They share identical panel cutout dimensions (6.35mm circular), bushing thread (1/4-40), termination style (solder lug), and electrical ratings (5A at 120V AC / 28V DC). Panel mounting and circuit connectivity remain unchanged.

Q: What is the difference between the two E-Switch substitute parts?

A: The 100SP1T2B5M1QEH and 100SP1T2B9M1QEH are functionally identical. Both are SPDT On-On toggle switches with matching electrical and mechanical specifications. Differentiation exists only in internal design variants within the E-Switch 100 series product line.

Q: Does the actuator type difference affect performance?

A: The C&K part features an anti-rotation actuator, while E-Switch alternatives use standard round actuators. Both designs function within the specified electrical and environmental parameters. Actuator type selection depends on application-specific mechanical requirements and panel design considerations.

Q: Are all three parts RoHS compliant?

A: Yes. The C&K 7101MPHZQE and both E-Switch substitute parts maintain ROHS3 compliance with unlimited moisture sensitivity rating (MSL 1).

Q: What is the significance of the 100,000 versus 40,000 cycle electrical life difference?

A: The C&K part specifies 100,000 electrical cycles while E-Switch parts specify 40,000 cycles. Both ratings remain valid within the stated electrical and environmental operating parameters. Application duty cycle requirements should guide selection when cycle life is a critical design factor.
