C&K 7201P3HCGE2 Toggle Switch DPDT Equivalent & Substitute Parts

Part Overview

The C&K 7201P3HCGE2 is a panel-mount toggle switch with DPDT (Double Pole Double Throw) configuration rated for 5A at 120V AC and 28V DC. This switch is part of the active 7000 series and features a flat anti-rotation actuator with PC pin termination. The product is ROHS3 compliant and maintains an electrical life of 100,000 cycles under standard operating conditions.

Substitute parts become necessary when the primary component experiences supply constraints, extended lead times, or when design requirements permit operation within alternative electrical specifications. The parts listed below share core mechanical compatibility while varying in electrical performance characteristics and lifecycle ratings.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by mechanical and electrical compatibility within the following constraints:

Mechanical Compatibility Requirements:

• Panel mount configuration with identical 6.35mm circular cutout
• 1/4-40 bushing thread specification
• PC pin termination style
• DPDT circuit with On-On function
• Operating temperature range of -30°C to 85°C

Electrical Compatibility Tiers:

Tier 1 - Full Electrical Equivalence: Parts maintaining 5A current rating at 120V AC and 28V DC specifications. These substitutes operate within the original design envelope without circuit modification.

Tier 2 - Reduced Electrical Rating: Parts with lower current ratings (0.4VA) and reduced voltage specifications (20V AC/DC). These substitutes require circuit analysis to confirm application compatibility and are suitable only for low-power switching applications.

The three substitute parts listed below meet mechanical compatibility requirements but differ in electrical performance and lifecycle characteristics.

Parameter Comparison

Engineering Selection Recommendations

E-Switch 100DP1T1B1M2QEH maintains full electrical equivalence to the C&K 7201P3HCGE2 with identical 5A current rating at 120V AC and 28V DC. This substitute is suitable for direct replacement in applications where the original specification is required. The reduced electrical life of 40,000 cycles versus 100,000 cycles must be evaluated against application duty cycle requirements. Both parts are ROHS3 compliant and active products.

E-Switch 100DP1T6B15M2RE and TE Connectivity 2-1825138-4 operate at reduced electrical ratings of 0.4VA at 20V AC/DC. These parts are mechanically compatible but electrically limited to low-power switching applications. Selection of these substitutes requires confirmation that circuit voltage and current demands do not exceed 0.4VA at 20V. The TE Connectivity part exhibits the lowest electrical life at 6,000 cycles and is suitable only for infrequent switching operations.

All substitute parts maintain ROHS3 compliance and active product status, ensuring regulatory alignment and ongoing manufacturer support.

Frequently Asked Questions (FAQ)

Q: Can the E-Switch 100DP1T1B1M2QEH directly replace the C&K 7201P3HCGE2?

A: Yes. The E-Switch 100DP1T1B1M2QEH maintains identical electrical specifications (5A at 120V AC and 28V DC) and mechanical compatibility (panel mount, DPDT, PC pin termination, 6.35mm cutout, 1/4-40 bushing). The primary difference is reduced electrical life (40,000 cycles versus 100,000 cycles). Substitution is valid for applications where this lifecycle rating is acceptable.

Q: What are the limitations of the E-Switch 100DP1T6B15M2RE and TE Connectivity 2-1825138-4?

A: Both parts operate at 0.4VA maximum at 20V AC/DC, compared to the original 5A at 120V AC and 28V DC. These substitutes are restricted to low-power signal switching applications and cannot handle the current or voltage levels of the original design. Circuit redesign or application verification is required before selection.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All three substitute parts listed are ROHS3 compliant and maintain active product status, ensuring regulatory compliance and manufacturer availability.

Q: How do actuator differences affect substitution?

A: The C&K 7201P3HCGE2 features a flat anti-rotation actuator at 11.43mm length. The E-Switch 100DP1T1B1M2QEH uses a standard round actuator at 10.41mm, while the E-Switch 100DP1T6B15M2RE retains the flat anti-rotation design at 12.30mm. Actuator geometry differences may affect panel aesthetics and operator feel but do not impact electrical function or mechanical mounting compatibility.

Q: What is the significance of electrical life ratings?

A: Electrical life indicates the number of switching cycles a component can perform before degradation. The C&K 7201P3HCGE2 is rated for 100,000 cycles, while E-Switch substitutes are rated for 40,000 cycles, and the TE Connectivity part for 6,000 cycles. Applications requiring frequent switching should prioritize parts with higher cycle ratings to ensure long-term reliability.

Q: Can packaging differences affect substitution?

A: The C&K 7201P3HCGE2 is supplied in tray packaging, while all substitute parts are supplied in bulk packaging. This difference affects inventory management and handling but does not impact component function or compatibility. Packaging selection should align with procurement and assembly requirements.
