E201MD9ABE Toggle Switch DPDT Equivalent & Substitute Parts

Part Overview

The E201MD9ABE is an active-status toggle switch manufactured by C&K, configured as a Double Pole Double Throw (DPDT) switch with On-On functionality. This through-hole, right-angle mounted component is rated for 0.4VA at 20V AC/DC operation and features epoxy sealed terminals with IP57 ingress protection. The part is ROHS3 compliant and carries unlimited moisture sensitivity level (MSL 1) classification.

Substitute parts are identified when equivalent circuit configurations, mounting types, and termination styles are available from alternative manufacturers, enabling procurement flexibility and supply chain continuity.

Substitute Part Grouping Explanation

The E-Switch model 100DP1T2B4M6QE qualifies as a substitute based on the following alignment criteria:

Matching Parameters:

• Circuit configuration: DPDT
• Switch function: On-On
• Mounting type: Through Hole, Right Angle
• Termination style: PC Pin
• Actuator type: Standard Round
• Actuator material: Brass, Chrome Plated
• Operating temperature range: -30°C ~ 85°C
• Electrical life: 40,000 Cycles
• Epoxy sealed terminals feature
• RoHS3 compliance
• MSL 1 (Unlimited) rating

Substitution Basis: The 100DP1T2B4M6QE maintains functional equivalence through identical circuit topology and mechanical interface specifications. Both parts employ DPDT switching logic with On-On operation, identical mounting geometry, and PC pin termination suitable for PCB assembly. The substitute part exceeds the electrical performance envelope of the E201MD9ABE, supporting higher current (5A vs. 0.4VA) and voltage ratings (120V AC / 28V DC vs. 20V AC/DC), making it suitable for applications within the original part's operational limits.

Parameter Comparison

Engineering Selection Recommendations

Both the E201MD9ABE and 100DP1T2B4M6QE maintain active product status with ROHS3 compliance and equivalent environmental certifications. The E201MD9ABE is suitable for applications requiring 20V maximum operation with 0.4VA current capacity. The 100DP1T2B4M6QE provides expanded electrical performance headroom, supporting up to 120V AC and 5A current, while maintaining identical mechanical and functional switching characteristics.

Selection between these parts should be based on application voltage and current requirements. The substitute part's higher ratings do not compromise compatibility with circuits designed for the original part's specifications. Both components satisfy identical ingress protection, temperature operating range, and electrical life cycle requirements.

Frequently Asked Questions (FAQ)

Q: Can the 100DP1T2B4M6QE directly replace the E201MD9ABE in existing designs?

A: Yes. Both parts share identical DPDT circuit topology, On-On switching function, through-hole right-angle mounting, and PC pin termination. The substitute part's higher voltage and current ratings are backward-compatible with applications designed for the E201MD9ABE's 20V / 0.4VA specifications.

Q: What is the primary difference between these two parts?

A: The 100DP1T2B4M6QE supports higher electrical performance: 120V AC / 28V DC and 5A current versus the E201MD9ABE's 20V AC/DC and 0.4VA rating. Both maintain identical switching logic, mechanical interface, and environmental specifications.

Q: Are there mechanical compatibility concerns due to actuator length differences?

A: The actuator length difference (6.86mm vs. 5.08mm) reflects design variations between manufacturers. Both parts employ standard round actuators with identical mounting geometry. Panel cutout and bushing specifications remain compatible for through-hole right-angle installation.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both the E201MD9ABE and 100DP1T2B4M6QE are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity ratings. Both carry EAR99 ECCN classification and identical HTSUS commodity codes.

Q: Which part should be selected for new designs?

A: Selection depends on application electrical requirements. For circuits operating at or below 20V with 0.4VA current, either part is suitable. For applications requiring higher voltage or current capacity, the 100DP1T2B4M6QE provides expanded operational margin while maintaining functional equivalence.
