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

Part Overview

The C&K 7201SPHCQE is an active production toggle switch with DPDT (Double Pole Double Throw) configuration rated for 5A at 120V AC and 28V DC. This panel-mount switch features anti-rotation actuator design with epoxy sealed terminals and operates across -30°C to 85°C. The part is RoHS3 compliant and REACH affected. Substitute parts may be required due to inventory constraints, end-of-life considerations, or application-specific parameter requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by matching the following critical parameters: circuit configuration (DPDT), switch function (On-On), mounting type (panel mount), panel cutout dimensions (6.35mm circular), bushing thread (1/4-40), termination style (PC pin), and operating temperature range (-30°C to 85°C).

The substitute parts are grouped into two categories based on electrical ratings:

Category A - Full Electrical Rating Match (5A @ 120V AC): E-Switch 100DP1T1B1M2QEH matches the primary electrical specifications of the main part with identical current and voltage ratings.

Category B - Reduced Electrical Rating (0.4VA @ 20V AC/DC): E-Switch 100DP1T6B15M2RE and TE Connectivity 2-1825138-4 operate at lower voltage and current levels. These parts are mechanically compatible but have different electrical performance envelopes.

Parameter Comparison

Engineering Selection Recommendations

E-Switch 100DP1T1B1M2QEH is the direct electrical equivalent to the C&K 7201SPHCQE. Both parts share identical current (5A AC/DC) and voltage ratings (120V AC / 28V DC), mechanical mounting specifications, and operating temperature range. This part is RoHS3 compliant and active in production. Selection of this substitute requires no circuit redesign or electrical parameter adjustment.

E-Switch 100DP1T6B15M2RE and TE Connectivity 2-1825138-4 are mechanically compatible but operate at reduced electrical ratings (0.4VA @ 20V AC/DC). These parts are suitable only for applications where the lower voltage and current specifications meet system requirements. Both are RoHS3 compliant and active in production. The TE Connectivity part has REACH affected status matching the main part.

All substitute parts maintain identical mechanical interfaces (panel cutout, bushing thread, termination style) and operating temperature specifications, ensuring direct physical installation compatibility.

Frequently Asked Questions (FAQ)

Q: Can the E-Switch 100DP1T1B1M2QEH directly replace the C&K 7201SPHCQE without circuit modification?

A: Yes. The E-Switch 100DP1T1B1M2QEH has identical electrical ratings (5A @ 120V AC, 28V DC), circuit configuration (DPDT On-On), and mechanical specifications. No circuit redesign is required.

Q: What is the key difference between the E-Switch 100DP1T1B1M2QEH and the other E-Switch substitute?

A: The 100DP1T1B1M2QEH maintains the full 5A @ 120V AC electrical rating. The 100DP1T6B15M2RE operates at reduced ratings (0.4VA @ 20V AC/DC) and is suitable only for low-voltage, low-current applications.

Q: Are all substitute parts mechanically interchangeable with the main part?

A: Yes. All substitute parts share the same panel cutout dimensions (6.35mm circular), bushing thread (1/4-40), and PC pin termination. Physical installation is identical across all parts.

Q: What compliance certifications apply to these parts?

A: All parts are RoHS3 compliant and rated for -30°C to 85°C operation. The C&K 7201SPHCQE and TE Connectivity 2-1825138-4 are REACH affected. The E-Switch parts are REACH unaffected.

Q: Can the reduced-rating parts (0.4VA @ 20V) be used in applications designed for 5A @ 120V?

A: No. The reduced-rating parts are not suitable for applications requiring 5A @ 120V operation. Use only in applications where the lower electrical specifications are compatible with system requirements.

Q: What is the electrical life difference between these parts?

A: The C&K 7201SPHCQE is rated for 100,000 cycles. The E-Switch parts are rated for 40,000 cycles. The TE Connectivity part is rated for 6,000 cycles. Select based on application duty cycle requirements.
