Toggle Switch DPDT 7201MD9ASE Equivalent & Substitute Parts

Part Overview

The C&K 7201MD9ASE is an active-status toggle switch with DPDT (Double Pole Double Throw) configuration, rated for 5A at 120V AC and 28V DC. This through-hole, right-angle mounted component features epoxy sealed terminals and operates across -30°C to 85°C. The part is ROHS3 compliant and REACH affected. Substitute parts are identified when equivalent electrical ratings, circuit configuration, mounting type, and termination style align with the original specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7201MD9ASE is determined by the following critical parameters:

• Circuit configuration must be DPDT
• Switch function must be On-On
• Current rating must be 5A (AC/DC)
• Voltage ratings must meet or exceed 120V AC and 28V DC
• Mounting type must be Through Hole, Right Angle
• Termination style must be PC Pin
• Actuator type must be Standard Round
• Operating temperature range must encompass -30°C to 85°C
• RoHS3 compliance required

The E-Switch 100DP1T2B4M6QE meets all critical substitution criteria. Variations in actuator length (6.86mm vs. 5.08mm) and electrical life cycles (100,000 vs. 40,000) do not disqualify substitution when the primary electrical and mechanical parameters align.

Parameter Comparison

Engineering Selection Recommendations

The E-Switch 100DP1T2B4M6QE qualifies as a direct substitute for the C&K 7201MD9ASE based on matching electrical specifications, circuit topology, and mechanical mounting requirements. Both parts are ROHS3 compliant and carry identical ECCN and HTSUS classifications.

Selection between the two parts should account for:

• Actuator length difference: The 7201MD9ASE has a 6.86mm actuator length versus 5.08mm for the 100DP1T2B4M6QE. Panel cutout and mechanical clearance must be verified for the application.
• Electrical life rating: The 7201MD9ASE is rated for 100,000 cycles compared to 40,000 cycles for the 100DP1T2B4M6QE. Applications requiring extended cycle life should prioritize the C&K part.
• REACH compliance: The 100DP1T2B4M6QE is REACH unaffected, while the 7201MD9ASE is REACH affected. Supply chain and regulatory requirements may influence selection.
• Packaging: The 7201MD9ASE is supplied in trays; the 100DP1T2B4M6QE is supplied in bulk.

Frequently Asked Questions (FAQ)

Q: Can the E-Switch 100DP1T2B4M6QE replace the C&K 7201MD9ASE in all applications?

A: The 100DP1T2B4M6QE meets all critical electrical and mechanical parameters. However, the shorter actuator length (5.08mm vs. 6.86mm) requires verification of panel cutout dimensions and mechanical clearance in the specific application.

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

A: The 7201MD9ASE is rated for 100,000 cycles while the 100DP1T2B4M6QE is rated for 40,000 cycles. For applications with high switching frequency or extended operational life requirements, the C&K part provides greater cycle durability.

Q: Are both parts RoHS compliant?

A: Yes, both the 7201MD9ASE and 100DP1T2B4M6QE are ROHS3 compliant. The 7201MD9ASE is REACH affected; the 100DP1T2B4M6QE is REACH unaffected.

Q: What are the packaging differences?

A: The C&K 7201MD9ASE is packaged in trays with 942 pieces in stock. The E-Switch 100DP1T2B4M6QE is packaged in bulk with 8223 pieces in stock. Packaging selection depends on procurement volume and inventory management requirements.

Q: Do both parts have identical termination and mounting specifications?

A: Yes, both parts feature PC Pin termination, through-hole mounting, and right-angle configuration. Mechanical and electrical interface compatibility is confirmed.
