Toggle Switch DPDT 7201SY4CQE Equivalent & Substitute Parts

Part Overview

The C&K 7201SY4CQE is an active-status toggle switch with DPDT (Double Pole Double Throw) configuration rated for 5A at 120V AC and 28V DC. This panel-mount switch features a standard round actuator with epoxy sealed terminals and is designed for general-purpose switching applications requiring reliable electrical performance across industrial and commercial environments. Equivalent and substitute parts are identified based on matching electrical ratings, mechanical compatibility, and functional circuit configuration to ensure direct replacement capability in existing designs.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 7201SY4CQE are grouped based on electrical and mechanical compatibility criteria. The primary substitution logic follows these parameters:

Critical Matching Parameters:

• Circuit configuration (DPDT)
• Switch function (On-On)
• Mounting type (Panel Mount)
• Panel cutout dimensions (Circular - 6.35mm Dia)
• Bushing thread (1/4-40)
• Termination style (PC Pin)
• Operating temperature range (-30°C to 85°C)

Electrical Rating Compatibility: Substitutes are classified into two groups based on current and voltage ratings:

Group 1 - Full Electrical Rating Match (5A @ 120V AC / 28V DC):

• E-Switch 100DP1T1B1M2QEH: Identical electrical specifications with 5A current rating and 120V AC / 28V DC voltage ratings

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

• E-Switch 100DP1T6B15M2RE
• TE Connectivity ALCOSWITCH 2-1825138-4

Group 2 parts share mechanical compatibility and circuit configuration but operate at lower electrical ratings. These are suitable only for applications where the reduced current and voltage specifications meet design requirements.

Parameter Comparison

Engineering Selection Recommendations

Direct Replacement (Electrical Rating Match): The E-Switch 100DP1T1B1M2QEH provides full electrical equivalence to the 7201SY4CQE with identical 5A current rating and 120V AC / 28V DC voltage specifications. Both parts are ROHS3 compliant and active-status products. This substitute is suitable for applications requiring the same electrical performance envelope. Note that the E-Switch part has a lower electrical life rating (40,000 cycles versus 100,000 cycles), which should be evaluated against application duty cycle requirements.

Conditional Substitution (Reduced Electrical Rating): The E-Switch 100DP1T6B15M2RE and TE Connectivity 2-1825138-4 are mechanically and functionally compatible but operate at reduced electrical ratings (0.4VA @ 20V AC/DC). These parts are suitable only for applications where the lower current and voltage specifications are acceptable. The TE Connectivity part exhibits significantly lower electrical life (6,000 cycles) and should be selected only when application duty cycles are minimal. Both reduced-rating substitutes are ROHS3 compliant and active-status products.

Compliance Considerations: All substitute parts maintain ROHS3 compliance and active product status. The E-Switch 100DP1T1B1M2QEH is REACH Unaffected, while the C&K original and TE Connectivity substitute are REACH Affected. The TE Connectivity part has Not Applicable MSL classification, whereas the C&K and E-Switch parts are MSL 1 (Unlimited).

Frequently Asked Questions (FAQ)

Q: Can the E-Switch 100DP1T1B1M2QEH be used as a direct replacement for the C&K 7201SY4CQE?

A: Yes. The E-Switch 100DP1T1B1M2QEH matches all critical electrical and mechanical parameters: 5A current rating, 120V AC / 28V DC voltage ratings, DPDT circuit configuration, panel mount with 1/4-40 bushing thread, and PC pin termination. Both parts operate across -30°C to 85°C. The primary difference is electrical life (40,000 cycles versus 100,000 cycles), which must be evaluated against application requirements.

Q: What is the difference between the full-rating and reduced-rating substitutes?

A: The E-Switch 100DP1T1B1M2QEH maintains the original 5A @ 120V AC / 28V DC electrical specifications. The E-Switch 100DP1T6B15M2RE and TE Connectivity 2-1825138-4 operate at 0.4VA @ 20V AC/DC. Reduced-rating parts are suitable only for low-power applications where these lower specifications are acceptable. All three maintain mechanical compatibility with the original part.

Q: Are all substitute parts panel-mount compatible with the original design?

A: Yes. All substitute parts share identical panel cutout dimensions (Circular - 6.35mm Dia) and bushing thread (1/4-40), ensuring mechanical compatibility with existing panel installations. PC pin termination is consistent across all parts.

Q: What is the electrical life difference, and does it matter?

A: The C&K 7201SY4CQE is rated for 100,000 electrical cycles. The E-Switch 100DP1T1B1M2QEH is rated for 40,000 cycles, and the TE Connectivity 2-1825138-4 is rated for only 6,000 cycles. Selection should be based on application duty cycle. High-frequency switching applications may require the original part or the E-Switch full-rating substitute with careful cycle analysis.

Q: Are all parts RoHS3 compliant?

A: Yes. All listed parts, including the original C&K 7201SY4CQE and all three substitutes, are ROHS3 compliant. REACH compliance status varies: E-Switch parts are REACH Unaffected, while C&K and TE Connectivity parts are REACH Affected.

Q: What packaging is available for each part?

A: The C&K 7201SY4CQE is supplied in Tray packaging. All E-Switch and TE Connectivity substitutes are supplied in Bulk packaging. Packaging format should be confirmed with procurement requirements.
