Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 7101MYCBE2 are grouped based on strict electrical and mechanical compatibility criteria. The primary substitution parameters are:

Critical Matching Parameters:

• Circuit configuration: SPDT (Single Pole Double Throw)
• Switch function: On-On
• Mounting type: Panel Mount
• Termination style: PC Pin
• Panel cutout dimensions: Circular - 6.35mm Dia
• Bushing thread: 1/4-40
• Operating temperature range: -30°C ~ 85°C

Electrical Rating Considerations: Substitute parts are classified into two groups based on current and voltage ratings relative to the original 0.4VA at 20V specification. Group 1 maintains identical electrical ratings (0.4VA at 20V), while Group 2 provides higher electrical ratings (5A at 120V AC / 28V DC) suitable for applications requiring increased power handling capacity.

Actuator Length Variation: Actuator length differences (5.08mm vs. 10.41mm) are noted as mechanical variations that may affect panel aesthetics and operator feel but do not prevent functional substitution when other parameters align.

Parameter Comparison

Engineering Selection Recommendations

Group 1 - Equivalent Electrical Rating (0.4VA at 20V):

The E-Switch 100SP1T1B1M2REH provides direct electrical equivalence to the 7101MYCBE2 with matching 0.4VA at 20V ratings and identical mechanical mounting parameters. This substitute is ROHS3 compliant and REACH unaffected, offering improved regulatory compliance compared to the original non-compliant part. The primary trade-off is reduced electrical life (40,000 cycles vs. 100,000 cycles) and increased actuator length (10.41mm vs. 5.08mm). This substitute is suitable for applications where regulatory compliance is prioritized and electrical life requirements do not exceed 40,000 cycles.

Group 2 - Higher Electrical Rating (5A at 120V AC / 28V DC):

The E-Switch 100SP1T1B3M2QEH and 100SP1T2B3M2QEH provide elevated electrical ratings suitable for applications requiring higher current and voltage handling. Both parts maintain identical mechanical mounting compatibility and operating temperature range. The 100SP1T2B3M2QEH preserves the original 5.08mm actuator length, while the 100SP1T1B3M2QEH features a 10.41mm actuator. Both are ROHS3 compliant and REACH unaffected. These substitutes are applicable when circuit requirements exceed the original 0.4VA specification and regulatory compliance is required.

Compliance Consideration:

All E-Switch substitutes are ROHS3 compliant and REACH unaffected, whereas the original C&K 7101MYCBE2 is RoHS non-compliant and REACH affected. Selection of substitute parts should align with end-application regulatory requirements and supply chain compliance mandates.

Frequently Asked Questions (FAQ)

Q: Can the E-Switch 100SP1T1B1M2REH directly replace the C&K 7101MYCBE2 in existing designs?

A: The 100SP1T1B1M2REH maintains electrical equivalence (0.4VA at 20V) and identical mechanical mounting parameters (panel cutout, bushing thread, termination style). The primary differences are increased actuator length (10.41mm vs. 5.08mm), reduced electrical life (40,000 vs. 100,000 cycles), and improved RoHS compliance. Direct substitution is possible when panel space accommodates the longer actuator and electrical life requirements do not exceed 40,000 cycles.

Q: What is the difference between the two E-Switch 5A variants?

A: Both 100SP1T1B3M2QEH and 100SP1T2B3M2QEH provide identical electrical ratings (5A at 120V AC / 28V DC) and mechanical compatibility. The distinction is actuator length: 100SP1T1B3M2QEH has 10.41mm length, while 100SP1T2B3M2QEH has 5.08mm length matching the original part. Selection depends on panel design and operator interface requirements.

Q: Are the E-Switch substitutes suitable for applications originally designed for 0.4VA at 20V?

A: Yes. The 100SP1T1B1M2REH is electrically equivalent at 0.4VA at 20V. The higher-rated variants (100SP1T1B3M2QEH and 100SP1T2B3M2QEH) are also suitable as they provide superior electrical ratings and are backward compatible with lower-voltage, lower-current applications. However, application-specific validation is required to confirm compatibility with existing circuit designs.

Q: What are the RoHS compliance implications of substitution?

A: The original C&K 7101MYCBE2 is RoHS non-compliant. All E-Switch substitutes are ROHS3 compliant. If the end application or supply chain requires RoHS compliance, E-Switch substitutes provide regulatory alignment. If RoHS compliance is not required, the original part remains viable.

Q: How does the reduced electrical life of E-Switch parts affect component selection?

A: The C&K 7101MYCBE2 is rated for 100,000 electrical cycles, while E-Switch substitutes are rated for 40,000 cycles. For applications with high switching frequency or extended operational life requirements, the reduced cycle rating must be evaluated against application duty cycles. If the application requires fewer than 40,000 switching events over the product lifetime, the E-Switch substitutes are suitable.

Q: Are there mechanical compatibility concerns with different actuator lengths?

A: Panel cutout dimensions (6.35mm circular) and bushing thread (1/4-40) are identical across all parts. Actuator length variation (5.08mm vs. 10.41mm) affects panel aesthetics and operator reach but does not prevent mechanical installation. Panel design must accommodate the selected actuator length to ensure proper operator interface and clearance.
