Toggle Switch DPDT 7201P4Y9ASE Equivalent & Substitute Parts

Part Overview

The 7201P4Y9ASE is an active-status toggle switch manufactured by C&K, classified as a DPDT (Double Pole Double Throw) switch with On-On functionality. This through-hole, right-angle mounted component is rated for 5A at 120V AC and 28V DC, making it suitable for general-purpose switching applications requiring dual-pole control. The part is currently in active production with 883 units in stock. Substitute parts are identified when equivalent electrical ratings, circuit configuration, and mechanical mounting compatibility are maintained across the allowed parameter set.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7201P4Y9ASE is determined by strict equivalence across the following critical parameters:

• Circuit configuration: DPDT only
• Switch function: On-On operation
• Current rating: 5A (AC/DC)
• Voltage ratings: 120V AC and 28V DC minimum
• Mounting type: Through hole, right angle
• Termination style: PC pin
• Operating temperature range: -30°C to 85°C or broader
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1 (Unlimited)

The substitute part 100DP1T2B4M6QE (E-Switch) meets all mandatory electrical and mechanical criteria. Variations in actuator type, actuator length, electrical life cycles, and packaging format do not disqualify substitution when core functional parameters remain equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the 7201P4Y9ASE and 100DP1T2B4M6QE are active-status products with ROHS3 compliance and MSL 1 rating, confirming regulatory and environmental suitability for equivalent applications. Selection between these parts should be based on:

• Actuator geometry requirements: The 7201P4Y9ASE features a flat anti-rotation actuator at 6.35mm length, while the 100DP1T2B4M6QE uses a standard round actuator at 5.08mm length. Panel cutout and operator interface specifications determine which actuator design is appropriate.
• Electrical life expectancy: The 7201P4Y9ASE is rated for 100,000 cycles versus 40,000 cycles for the 100DP1T2B4M6QE. Applications requiring extended operational life should prioritize the 7201P4Y9ASE.
• Packaging and inventory: The 7201P4Y9ASE is supplied in tray packaging with 883 units available, while the 100DP1T2B4M6QE is supplied in bulk packaging with 8223 units available. Procurement volume and handling requirements may influence selection.

Frequently Asked Questions (FAQ)

Q: Can the 100DP1T2B4M6QE replace the 7201P4Y9ASE in existing designs?

A: Yes, provided that the actuator geometry (flat anti-rotation versus standard round) and actuator length (6.35mm versus 5.08mm) do not conflict with panel cutout dimensions or mechanical constraints. The electrical and functional parameters are equivalent.

Q: What is the significance of the difference in electrical life ratings?

A: The 7201P4Y9ASE is rated for 100,000 switching cycles while the 100DP1T2B4M6QE is rated for 40,000 cycles. For applications with high switching frequency or extended service life requirements, the 7201P4Y9ASE provides greater operational durability.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the 7201P4Y9ASE and 100DP1T2B4M6QE are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, confirming compliance with current environmental and handling standards.

Q: Does packaging format affect electrical performance?

A: No. The tray packaging of the 7201P4Y9ASE and bulk packaging of the 100DP1T2B4M6QE do not affect electrical performance or functional characteristics. Packaging selection is based on procurement volume and logistics requirements.

Q: Are there any voltage or current limitations when substituting?

A: No. Both parts are rated identically at 5A (AC/DC), 120V AC, and 28V DC. Substitution does not introduce voltage or current derating.
