T201MH9CBE Toggle Switch DPDT Equivalent & Substitute Parts

Part Overview

The T201MH9CBE is a through-hole mounted toggle switch manufactured by C&K, configured as a Double Pole Double Throw (DPDT) switch with On-On functionality. This switch is rated for 0.4VA at 20V AC/DC and features epoxy sealed terminals with a brass, chrome-plated actuator. The part is currently active in production status with 689 units in stock.

Equivalent and substitute parts are identified when applications require alternative sourcing due to inventory constraints, lead time considerations, or when design specifications allow for compatible alternatives meeting the same electrical and mechanical requirements.

Engineering Selection Recommendations

For Direct Replacement (Identical Electrical Specifications):

200MDP1T2B2M2RE and TT21NGPC1 are direct electrical equivalents to the T201MH9CBE, matching the 0.4VA current rating and 20V voltage specifications. Both parts maintain ROHS3 compliance and active production status. The 200MDP1T2B2M2RE offers lower electrical life (30,000 cycles versus 60,000), while TT21NGPC1 provides extended electrical life (80,000 cycles) but carries RoHS non-compliant status.

For Higher Voltage Applications:

B22JP is suitable for applications requiring 28V operation while maintaining the 0.4VA current rating and ROHS3 compliance. Actuator length is 6.30mm, which may require panel cutout verification.

For Higher Power Requirements:

200MDP1T2B2M2QE accommodates applications requiring 3A at 120V AC or 28V DC. This part is selected only when circuit design specifications exceed the 0.4VA/20V ratings of the primary part.

Frequently Asked Questions (FAQ)

Q: Can 200MDP1T2B2M2RE be used as a direct replacement for T201MH9CBE?

A: Yes. Both parts share identical electrical specifications (0.4VA, 20V AC/DC), DPDT On-On configuration, through-hole mounting, PC pin termination, and operating temperature range. Actuator length differs by 0.11mm (5.33mm versus 5.44mm), which is within typical mechanical tolerance for panel-mounted applications.

Q: What is the difference between TT21NGPC1 and T201MH9CBE?

A: Electrical specifications are identical. TT21NGPC1 provides superior electrical life (80,000 cycles versus 60,000 cycles) but is RoHS non-compliant, whereas T201MH9CBE is ROHS3 compliant. Selection depends on regulatory requirements and cycle life demands.

Q: When should 200MDP1T2B2M2QE be selected instead of T201MH9CBE?

A: 200MDP1T2B2M2QE is selected only when circuit requirements exceed 0.4VA or 20V specifications. This part supports 3A at 120V AC or 28V DC and is not a direct replacement for standard 0.4VA/20V applications.

Q: Is B22JP compatible with 20V circuits designed for T201MH9CBE?

A: Yes. B22JP is rated for 28V AC/DC, which exceeds the 20V requirement. The 0.4VA current rating matches the original specification. Mechanical compatibility requires verification of the 6.30mm actuator length against panel cutout dimensions.

Q: Are all substitute parts available in the same packaging as T201MH9CBE?

A: T201MH9CBE is supplied in Tray packaging. Substitute parts are supplied in Bulk packaging. Packaging format may affect procurement and handling procedures.
