Substitute Part Grouping Explanation

Substitution of the 7105SY4CQE is permissible when the alternative component maintains the following critical parameters:

• Circuit configuration: SPDT
• Switch function: Mom-Off-Mom
• Current rating: 5A (AC/DC)
• Voltage rating: 120V AC / 28V DC minimum
• Mounting type: Panel Mount
• Panel cutout dimensions: Circular - 6.35mm Dia
• Bushing thread: 1/4-40
• Termination style: PC Pin
• Operating temperature range: -30°C ~ 85°C or wider
• Electrical life: 40,000 cycles minimum

The substitute part 100SP4T6B11M2QEH (E-Switch) satisfies all critical electrical and mechanical parameters required for direct substitution. Both parts feature identical circuit topology, current and voltage ratings, panel mounting specifications, and environmental operating conditions.

Parameter Comparison

Engineering Selection Recommendations

Both the 7105SY4CQE and 100SP4T6B11M2QEH are active production components with ROHS3 compliance and equivalent electrical performance. Selection between these parts should be based on:

• Availability and lead time requirements
• Actuator geometry compatibility with panel design (standard round vs. flat anti-rotation; 10.67mm vs. 12.30mm length)
• Manufacturer preference or qualification requirements
• Supply chain considerations

The 100SP4T6B11M2QEH offers higher current inventory availability (1315 units vs. 1096 units) while maintaining full electrical and mechanical compatibility for SPDT Mom-Off-Mom switching applications at 5A/120V AC and 5A/28V DC.

Frequently Asked Questions (FAQ)

Q: Can the 100SP4T6B11M2QEH directly replace the 7105SY4CQE in existing designs?

A: Yes, provided the actuator geometry difference is accommodated. The 100SP4T6B11M2QEH features a flat anti-rotation actuator at 12.30mm length versus the 7105SY4CQE standard round actuator at 10.67mm. Panel cutout dimensions and bushing threads are identical (6.35mm circular, 1/4-40), ensuring mechanical compatibility. Verify actuator clearance and user interface requirements in your specific application.

Q: Are the electrical ratings identical between these parts?

A: Yes. Both parts are rated for 5A at 120V AC and 28V DC with SPDT Mom-Off-Mom switching function and 40,000 cycle electrical life. Operating temperature range is identical at -30°C to 85°C.

Q: What is the difference in actuator design?

A: The 7105SY4CQE uses a standard round actuator, while the 100SP4T6B11M2QEH uses a flat anti-rotation design. The flat anti-rotation actuator prevents unintended rotation during operation. The 100SP4T6B11M2QEH actuator is 1.63mm longer (12.30mm vs. 10.67mm).

Q: Are both parts RoHS compliant?

A: Yes. Both the 7105SY4CQE and 100SP4T6B11M2QEH are ROHS3 compliant.

Q: What termination style do these parts use?

A: Both parts use PC pin termination, suitable for direct PCB mounting or wire harness connection via standard pin headers.
