C&K 7201P3YZBES Toggle Switch DPDT Equivalent & Substitute Parts

Part Overview

The C&K 7201P3YZBES is an active production toggle switch with DPDT (Double Pole Double Throw) configuration, rated for 0.4VA at 20V AC/DC. This panel-mount switch features a flat anti-rotation actuator with satin chrome finish and solder lug termination. The part is ROHS3 compliant and maintains an electrical life rating of 100,000 cycles. Substitute parts are identified when equivalent electrical ratings, mechanical mounting specifications, and circuit configurations are maintained across alternative manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7201P3YZBES is determined by strict equivalence in the following parameters:

• Circuit configuration (DPDT required)
• Switch function (On-On required)
• Current rating (0.4VA AC/DC required)
• Voltage rating (20V AC/DC required)
• Mounting type (Panel Mount required)
• Panel cutout dimensions (Circular 6.35mm Dia required)
• Bushing thread (1/4-40 required)
• Termination style (Solder Lug required)
• Operating temperature range (-30°C ~ 85°C minimum required)

Substitute parts are grouped into two categories based on electrical equivalence:

Category A - Full Electrical Equivalents: Parts maintaining identical current and voltage ratings (0.4VA at 20V AC/DC). These parts are direct functional replacements.

Category B - Higher Rated Alternatives: Parts with elevated current or voltage ratings. These parts exceed the electrical requirements of the main part and are suitable for applications requiring higher performance margins.

Parameter Comparison

Engineering Selection Recommendations

100DP1T1B1M1REH and 100DP1T6B11M1REH (E-Switch): These parts maintain electrical equivalence to the 7201P3YZBES with identical current and voltage ratings (0.4VA at 20V AC/DC). Both are ROHS3 compliant and active production parts. The primary difference is actuator geometry: 100DP1T1B1M1REH features a standard round actuator at 10.41mm length, while 100DP1T6B11M1REH maintains the flat anti-rotation actuator design at 12.30mm length. Electrical life is reduced to 40,000 cycles compared to the original part's 100,000 cycles. Selection between these two depends on actuator preference and mechanical clearance requirements.

100DP1T6B11M1QEH (E-Switch): This part exceeds the electrical specifications of the 7201P3YZBES with a 5A current rating at 120V AC and 28V DC. It maintains DPDT configuration, panel mount specifications, and ROHS3 compliance. This part is suitable for applications requiring higher electrical performance margins. Electrical life is 40,000 cycles.

All substitute parts maintain mechanical compatibility through identical panel cutout dimensions (6.35mm circular) and bushing thread (1/4-40), ensuring direct mechanical interchange in panel-mount applications.

Frequently Asked Questions (FAQ)

Q: Can 100DP1T6B11M1QEH be used as a direct replacement for 7201P3YZBES?

A: Yes, mechanically and functionally. The 100DP1T6B11M1QEH maintains identical DPDT configuration, panel mount specifications, and solder lug termination. However, it is rated for 5A at 120V AC, exceeding the original part's 0.4VA at 20V specification. This higher rating does not prevent substitution in applications designed for the lower-rated part.

Q: What is the difference between 100DP1T1B1M1REH and 100DP1T6B11M1REH?

A: Both parts are electrically equivalent to the 7201P3YZBES at 0.4VA 20V. The primary differences are actuator type and length. 100DP1T1B1M1REH uses a standard round actuator at 10.41mm, while 100DP1T6B11M1REH uses a flat anti-rotation actuator at 12.30mm. Selection depends on panel design and actuator preference.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. The 7201P3YZBES and all listed substitute parts (100DP1T1B1M1REH, 100DP1T6B11M1REH, 100DP1T6B11M1QEH) are ROHS3 compliant.

Q: What is the impact of reduced electrical life in substitute parts?

A: The 7201P3YZBES is rated for 100,000 electrical cycles, while E-Switch substitutes are rated for 40,000 cycles. This difference should be evaluated against application duty cycle requirements. Applications with lower switching frequency may not be affected by this specification difference.

Q: Do all parts use the same panel cutout and bushing specifications?

A: Yes. All parts listed use a circular 6.35mm diameter panel cutout with 1/4-40 bushing thread, ensuring mechanical interchangeability in panel-mount applications.

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

A: The 7201P3YZBES is supplied in Tray packaging, while E-Switch substitutes are supplied in Bulk packaging. This affects handling and storage but does not impact electrical or mechanical function.
