Toggle Switch SPDT 7101SYCGE Equivalent & Substitute Parts

Part Overview

The C&K 7101SYCGE is an active-status toggle switch with SPDT (Single Pole Double Throw) configuration, rated for 5A at 120V AC and 28V DC. This panel-mount switch features a standard round actuator with PC pin termination and epoxy sealed terminals. The part is currently in stock with 1,020 units available. Substitute parts are necessary when the original manufacturer part is unavailable, when alternative compliance certifications are required, or when application-specific electrical ratings differ from the primary specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for toggle switch SPDT parts is determined by strict alignment of the following critical parameters:

Primary Compatibility Criteria:

• Circuit configuration (SPDT required)
• Switch function (On-On required)
• Mounting type (Panel Mount required)
• Actuator type (Standard Round required)
• Panel cutout dimensions (Circular - 6.35mm Dia required)
• Bushing thread (1/4-40 required)
• Termination style (PC Pin required)

Electrical Compatibility Criteria:

• Current rating must meet or exceed application requirements
• Voltage ratings (AC and DC) must meet or exceed application requirements
• Operating temperature range must encompass application environment

Mechanical Compatibility Criteria:

• Actuator length variance within acceptable mechanical envelope
• Actuator material consistency (Brass, Chrome Plated)
• Epoxy sealed terminals feature maintained

The two E-Switch parts listed (100SP1T1B1M2QEH and 100SP1T1B1M2REH) share identical mechanical and mounting specifications with the primary part. However, electrical ratings differ and must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

100SP1T1B1M2QEH (E-Switch) - Full Electrical Equivalent

This part maintains identical electrical ratings (5A at 120V AC / 28V DC) and all mechanical specifications as the primary part. The actuator length is 0.26mm shorter (10.41mm vs. 10.67mm), which remains within acceptable mechanical tolerance for panel-mount applications. This substitute achieves ROHS3 compliance and REACH unaffected status, providing regulatory advantages over the primary part. Electrical life is rated at 40,000 cycles compared to 100,000 cycles for the primary part. Current inventory is 4,017 units.

100SP1T1B1M2REH (E-Switch) - Reduced Electrical Rating

This part shares identical mechanical and mounting specifications but operates at reduced electrical ratings (0.4VA at 20V AC/DC). This substitute is applicable only for applications with electrical requirements not exceeding 0.4VA at 20V. Like the QEH variant, this part achieves ROHS3 compliance and REACH unaffected status. Electrical life is 40,000 cycles. Current inventory is 1,254 units.

Frequently Asked Questions (FAQ)

Q: Can 100SP1T1B1M2QEH directly replace 7101SYCGE in all applications?

A: Yes, for applications requiring 5A at 120V AC or 28V DC. The electrical ratings are identical. The 0.26mm difference in actuator length does not affect panel-mount compatibility. The primary consideration is the reduced electrical life specification (40,000 cycles vs. 100,000 cycles).

Q: When should 100SP1T1B1M2REH be used instead of the primary part?

A: Only when application electrical requirements do not exceed 0.4VA at 20V AC/DC. This part is not suitable for applications requiring the full 5A at 120V AC rating of the primary part.

Q: What are the compliance differences between these parts?

A: The primary part (7101SYCGE) is RoHS non-compliant and REACH Affected. Both E-Switch substitutes (100SP1T1B1M2QEH and 100SP1T1B1M2REH) are ROHS3 Compliant and REACH Unaffected, providing regulatory advantages for applications subject to these requirements.

Q: Are the panel cutout dimensions identical across all three parts?

A: Yes. All three parts require a circular panel cutout of 6.35mm diameter with 1/4-40 bushing thread, ensuring mechanical interchangeability in panel-mount applications.

Q: How do electrical life ratings affect part selection?

A: The primary part is rated for 100,000 electrical cycles, while both E-Switch substitutes are rated for 40,000 cycles. Applications with high switching frequency should account for this difference in expected service life.
