Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the C&K 7101MPD9ABE is determined by the following critical parameters:

• Circuit and Function Match: SPDT configuration with On-On switching function
• Electrical Ratings: 0.4VA current capacity at 20V AC/DC
• Mechanical Compatibility: Through-hole, right-angle mounting with PC pin termination
• Environmental Compliance: RoHS3 compliance and MSL 1 rating
• Operating Conditions: Temperature range -30°C to 85°C

The E-Switch 100SP1T2B4M6RE meets all mandatory electrical and mechanical parameters. Differences in actuator type (anti-rotation versus standard round) and actuator length (6.86mm versus 5.08mm) represent design variations that do not affect core substitution eligibility but may influence physical fit and user interface characteristics. The reduced electrical life specification (40,000 cycles versus 100,000 cycles) represents a functional difference that must be evaluated against application duty cycle requirements.

Parameter Comparison

Engineering Selection Recommendations

Both components are active products with RoHS3 compliance and MSL 1 ratings, meeting regulatory requirements for industrial and commercial applications. The C&K 7101MPD9ABE provides extended electrical life at 100,000 cycles, suitable for high-cycle-count applications. The E-Switch 100SP1T2B4M6RE offers equivalent electrical performance with a 40,000-cycle rating, appropriate for moderate-duty applications. Selection between these parts should be based on application duty cycle requirements and physical space constraints related to actuator length and type differences.

Frequently Asked Questions (FAQ)

Q: Can the E-Switch 100SP1T2B4M6RE directly replace the C&K 7101MPD9ABE in all applications?

A: Both parts share identical electrical ratings (0.4VA, 20V AC/DC), circuit configuration (SPDT), and mounting specifications (through-hole, right-angle, PC pin termination). The primary consideration is electrical life: the E-Switch part is rated for 40,000 cycles versus 100,000 cycles for the C&K part. Applications with lower cycle counts are compatible; high-cycle applications require verification against the E-Switch specification.

Q: What is the significance of the actuator type difference?

A: The C&K 7101MPD9ABE features an anti-rotation actuator, while the E-Switch 100SP1T2B4M6RE uses a standard round actuator. This affects physical handling and panel mounting characteristics but does not impact electrical function. Panel cutout compatibility and user interface feel may differ.

Q: Are both parts compliant with environmental regulations?

A: Yes. Both components are RoHS3 compliant with MSL 1 (unlimited moisture sensitivity level), suitable for standard industrial and commercial environments. The C&K part carries REACH Affected status, while the E-Switch part is REACH Unaffected; verify regional regulatory requirements for your application.

Q: Does the 1.78mm actuator length difference affect PCB layout?

A: The C&K part has a 6.86mm actuator length versus 5.08mm for the E-Switch part. This 1.78mm difference may impact clearance in space-constrained designs. Verify panel cutout dimensions and surrounding component placement before substitution.

Q: What inventory considerations apply to these parts?

A: The C&K 7101MPD9ABE has 826 pieces in stock, while the E-Switch 100SP1T2B4M6RE has 3,426 pieces available. Supply chain planning should account for these inventory levels when selecting between equivalent parts.
