7201SH3CQE Toggle Switch DPDT Equivalent & Substitute Parts

Part Overview

The 7201SH3CQE is an active production toggle switch manufactured by C&K, classified as a DPDT (Double Pole Double Throw) panel mount switch rated for 5A at 120V AC and 28V DC. This component features a standard round actuator with epoxy sealed terminals and is designed for applications requiring reliable switching in industrial and commercial environments. Substitute parts may be required due to inventory constraints, supply chain considerations, or specific application requirements where alternative electrical or mechanical parameters are acceptable.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7201SH3CQE is determined by the following critical parameters: circuit configuration (DPDT), switch function (On-On), mounting type (Panel Mount), termination style (PC Pin), panel cutout dimensions (Circular - 6.35mm Dia), bushing thread (1/4-40), and operating temperature range (-30°C ~ 85°C).

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

Category 1 - Full Electrical Rating Match (5A @ 120V AC):

• 100DP1T1B1M2QEH (E-Switch): Maintains identical AC/DC current and voltage ratings as the main part. Mechanical parameters including actuator type, length, and panel dimensions are compatible.

Category 2 - Reduced Electrical Rating (0.4VA @ 20V AC/DC):

• 100DP1T6B15M2RE (E-Switch): Features reduced current and voltage ratings with a flat anti-rotation actuator and longer actuator length (12.30mm).
• 2-1825138-4 (TE Connectivity ALCOSWITCH Switches): Features reduced current and voltage ratings with standard round actuator and lower electrical life (6,000 cycles).

All substitute parts maintain DPDT circuit configuration, On-On switch function, panel mount design, PC pin termination, and compatible panel cutout and bushing specifications.

Parameter Comparison

Engineering Selection Recommendations

For applications requiring 5A @ 120V AC operation: The 100DP1T1B1M2QEH from E-Switch is the direct electrical equivalent to the 7201SH3CQE. Both parts maintain identical current and voltage ratings, operating temperature range, and mechanical compatibility. The E-Switch part is ROHS3 compliant and active in production. The primary difference is reduced electrical life (40,000 cycles versus 100,000 cycles) and REACH compliance status variation.

For applications with reduced electrical requirements (0.4VA @ 20V AC/DC): Both the 100DP1T6B15M2RE and 2-1825138-4 are suitable only for circuits operating at 20V or lower with current demands not exceeding 0.4VA. The 100DP1T6B15M2RE features a flat anti-rotation actuator and longer actuator length (12.30mm), which may affect panel cutout clearance. The 2-1825138-4 maintains a standard round actuator but exhibits significantly lower electrical life (6,000 cycles) and is not applicable for MSL rating.

All substitute parts maintain ROHS3 compliance and active production status, ensuring regulatory alignment and supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can the 100DP1T1B1M2QEH directly replace the 7201SH3CQE in all applications? A: The 100DP1T1B1M2QEH is electrically and mechanically compatible with the 7201SH3CQE for applications operating at 5A and 120V AC. The primary consideration is reduced electrical life (40,000 cycles versus 100,000 cycles), which may impact applications requiring extended cycle counts.

Q: What are the limitations of the 100DP1T6B15M2RE and 2-1825138-4 substitutes? A: Both parts are rated for 0.4VA at 20V maximum, making them unsuitable for the 7201SH3CQE's 5A @ 120V AC specification. These parts are only applicable for low-voltage, low-current applications. Additionally, the 100DP1T6B15M2RE features a flat anti-rotation actuator with 12.30mm length, requiring verification of panel cutout clearance.

Q: Are all substitute parts RoHS compliant? A: Yes, all substitute parts listed (100DP1T1B1M2QEH, 100DP1T6B15M2RE, and 2-1825138-4) are ROHS3 compliant, matching the compliance status of the 7201SH3CQE.

Q: What is the impact of different actuator types on mechanical compatibility? A: The 7201SH3CQE and most substitutes use a standard round actuator. The 100DP1T6B15M2RE uses a flat anti-rotation actuator with a longer length (12.30mm versus 10.16mm). Panel cutout dimensions remain compatible (Circular - 6.35mm Dia), but the increased actuator length may require clearance verification in confined panel spaces.

Q: How do electrical life ratings affect part selection? A: The 7201SH3CQE is rated for 100,000 electrical cycles. The E-Switch alternatives (100DP1T1B1M2QEH and 100DP1T6B15M2RE) are rated for 40,000 cycles, while the TE Connectivity part (2-1825138-4) is rated for only 6,000 cycles. Applications with high switching frequency should prioritize parts with higher electrical life ratings.

Q: What packaging options are available? A: The 7201SH3CQE is supplied in Tray packaging. The substitute parts are supplied in Bulk packaging. Packaging format should be confirmed with procurement requirements.
