• Voltage rating: 20V AC and 20V DC
• Mounting type: Panel Mount
• Panel cutout dimensions: Circular - 6.35mm Dia
• Bushing thread: 1/4-40
• Termination style: Solder Lug
• Operating temperature range: -30°C to 85°C
• Electrical life: 40,000 Cycles

The E-Switch 100SP3T1B1M1REH meets all critical electrical and mechanical parameters, providing direct functional equivalence. The E-Switch 100SP3T1B1M1QEH shares the same mechanical interface and circuit configuration but operates at higher electrical ratings (5A, 120V AC/28V DC), making it suitable for applications with lower electrical stress requirements.

Parameter Comparison

Engineering Selection Recommendations

100SP3T1B1M1REH (E-Switch): This substitute provides direct electrical and mechanical equivalence to the 7103P3DZBES. Both components are rated for 0.4VA at 20V, operate across the same temperature range, and share identical mechanical interfaces. Both are ROHS3 compliant and maintain 40,000 cycle electrical life ratings. This part is the primary substitute for direct replacement applications.

100SP3T1B1M1QEH (E-Switch): This substitute shares the same mechanical interface and circuit configuration as the primary part but operates at higher electrical ratings (5A, 120V AC/28V DC). This component is suitable for applications where the 7103P3DZBES is specified but the actual circuit operates at lower electrical stress levels. Both parts are ROHS3 compliant with identical mechanical mounting characteristics and operating temperature ranges.

Frequently Asked Questions (FAQ)

Q: Can the 100SP3T1B1M1REH directly replace the 7103P3DZBES? A: Yes. The 100SP3T1B1M1REH matches all critical electrical parameters (0.4VA, 20V AC/DC), circuit configuration (SPDT), switch function (On-Off-On), and mechanical specifications (panel mount, 6.35mm cutout, 1/4-40 bushing, solder lug termination). Both components operate across -30°C to 85°C and provide 40,000 cycle electrical life.

Q: When should the 100SP3T1B1M1QEH be used instead of the 100SP3T1B1M1REH? A: The 100SP3T1B1M1QEH is selected when higher electrical ratings are required or when sourcing the exact 0.4VA rated component is not feasible. It provides the same mechanical interface and circuit topology but operates at 5A and 120V AC, offering greater electrical capacity for applications with lower actual circuit stress.

Q: Are all substitute parts panel mount compatible with the original specification? A: Yes. All listed substitutes share identical panel mount specifications: circular 6.35mm diameter cutout and 1/4-40 bushing thread. All use solder lug termination and are suitable for the same mechanical installation.

Q: What compliance certifications apply to these substitutes? A: All parts listed are ROHS3 compliant. The 100SP3T1B1M1REH is REACH Unaffected, while the 7103P3DZBES is REACH Affected. Both E-Switch substitutes carry EAR99 ECCN classification.

Q: Do the substitute parts maintain the same electrical life rating? A: Yes. All listed parts provide 40,000 cycle electrical life, ensuring equivalent durability and reliability across the substitution group.
