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

Part Overview

The C&K 7201SPDCQE 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 is suitable for general-purpose switching applications requiring robust electrical performance. Substitute parts may be required due to inventory constraints, end-of-life considerations, or specific application requirements where alternative electrical or mechanical specifications are acceptable.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment with the following core 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), operating temperature range (-30°C to 85°C), and RoHS3 compliance status.

The substitute parts listed fall into two distinct electrical performance categories:

Category A - Full Electrical Equivalence: Parts maintaining the 5A/120V AC rating with identical core mechanical specifications. These parts are direct functional replacements for applications requiring the full current and voltage capacity of the main part.

Category B - Reduced Electrical Rating: Parts with reduced current (0.4VA) and voltage (20V AC/DC) ratings. These parts are suitable only for applications where the lower electrical specifications are acceptable and do not exceed the substitute part's rated capacity.

All substitute parts maintain DPDT configuration, On-On function, panel mount design, identical panel cutout and bushing specifications, PC pin termination, and the required operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

E-Switch 100DP1T1B1M2QEH is the primary substitute for the C&K 7201SPDCQE. This part maintains full electrical equivalence with identical 5A/120V AC and 28V DC ratings, matching all mechanical specifications including panel cutout, bushing thread, and termination style. Both parts are ROHS3 compliant and active production items. The primary difference is the standard round actuator versus the anti-rotation design of the main part; however, the mechanical interface and electrical performance are fully compatible.

E-Switch 100DP1T6B15M2RE and TE Connectivity 2-1825138-4 are substitutes only for applications where reduced electrical specifications are acceptable. Both parts are rated for 0.4VA at 20V AC/DC, representing a significant reduction from the main part's 5A/120V AC capability. These parts maintain identical mechanical specifications and panel mount compatibility but must not be used in applications requiring the higher current or voltage capacity of the main part. Both substitute parts are ROHS3 compliant and active production items.

All substitute parts maintain the required operating temperature range of -30°C to 85°C and are suitable for direct panel mount installation with no mechanical modification required.

Frequently Asked Questions (FAQ)

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

A: Yes. The E-Switch 100DP1T1B1M2QEH maintains full electrical equivalence with 5A/120V AC and 28V DC ratings. All mechanical specifications including panel cutout diameter (6.35mm), bushing thread (1/4-40), and PC pin termination are identical. The actuator design differs (standard round versus anti-rotation), but the electrical and mechanical interface compatibility is complete.

Q: What is the difference between the substitute parts?

A: E-Switch 100DP1T1B1M2QEH provides full electrical equivalence to the main part (5A/120V AC). E-Switch 100DP1T6B15M2RE and TE Connectivity 2-1825138-4 both feature reduced electrical ratings (0.4VA/20V AC/DC) and are suitable only for low-power applications. All three maintain identical mechanical specifications and panel mount compatibility.

Q: Can I use the E-Switch 100DP1T6B15M2RE or TE Connectivity 2-1825138-4 in place of the C&K 7201SPDCQE?

A: Only if your application does not exceed 0.4VA at 20V AC/DC. These parts have significantly lower electrical ratings and must not be used in applications requiring the 5A/120V AC capability of the main part. Verify your circuit requirements before substitution.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. The C&K 7201SPDCQE and all three substitute parts are ROHS3 compliant. The TE Connectivity 2-1825138-4 has Not Applicable moisture sensitivity level, while the C&K and E-Switch parts are rated MSL 1 (Unlimited).

Q: Do the substitute parts require any panel modification?

A: No. All substitute parts maintain the identical 6.35mm circular panel cutout dimension and 1/4-40 bushing thread specification. No mechanical modification to the panel or mounting hardware is required.

Q: What is the electrical life difference between the main part and substitutes?

A: The C&K 7201SPDCQE is rated for 100,000 electrical cycles. The E-Switch parts are rated for 40,000 cycles, and the TE Connectivity part is rated for 6,000 cycles. Select based on your application's cycle life requirements.
