MKP1V240RL Equivalent & Substitute Parts

Part Overview

The MKP1V240RL is a SIDAC thyristor manufactured by onsemi, rated for 220–250V breakover voltage with 900mA peak output current in an axial (DO-204AL/DO-41) package. This component is classified as obsolete, making equivalent substitutes necessary for new designs and ongoing production requirements. The part operates across the industrial temperature range of -40°C to 125°C and is suitable for applications requiring precise voltage triggering in thyristor circuits.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the MKP1V240RL is determined by matching the following critical electrical and mechanical parameters:

• Voltage - Breakover: 220–250V (exact match required)
• Current - Peak Output: 900mA minimum (equal or higher acceptable)
• Package Type: Axial configuration (DO-204AL/DO-41)
• Operating Temperature Range: -40°C to 125°C (minimum requirement)

Two substitute categories are identified:

Direct Substitute (Axial Package): MKP1V240RLG maintains identical electrical specifications and axial packaging, providing pin-for-pin compatibility.

Similar Substitute (Alternative Package): K2400E70 matches the voltage and temperature specifications but uses a TO-92 package with higher peak current (1A) and different breakover current characteristics (10µA vs. 35µA).

Parameter Comparison

Engineering Selection Recommendations

MKP1V240RLG is the primary substitute for the obsolete MKP1V240RL. It provides identical electrical performance and axial packaging, ensuring direct compatibility in existing circuit layouts. The part is manufactured by Littelfuse Inc., is in active production status, and meets ROHS3 compliance requirements. This substitute eliminates the obsolescence risk associated with the original onsemi component.

K2400E70 serves as an alternative when package form factor can be modified to accommodate TO-92 configuration. This part maintains the 220–250V breakover voltage and operating temperature range but introduces differences in breakover current (10µA vs. 35µA) and hold current (150mA vs. 100mA). The higher peak current rating (1A) provides additional margin for applications with variable load conditions. This substitute is suitable only when circuit design permits package substitution and the altered electrical characteristics are acceptable for the application.

Frequently Asked Questions (FAQ)

Q: Can MKP1V240RLG be used as a direct replacement for MKP1V240RL?

A: Yes. MKP1V240RLG matches all critical electrical parameters (220–250V breakover, 900mA peak output, 35µA breakover current, 100mA hold current) and uses identical axial packaging. No circuit modifications are required.

Q: What are the key differences between MKP1V240RLG and K2400E70?

A: The primary differences are package type (axial vs. TO-92) and breakover current specification (35µA vs. 10µA). K2400E70 also has higher hold current (150mA) and peak output current (1A). These differences require circuit evaluation before substitution.

Q: Is K2400E70 suitable for applications requiring the exact 35µA breakover current specification?

A: No. K2400E70 specifies 10µA breakover current, which differs from the original 35µA specification. Applications with tight triggering current tolerances must use MKP1V240RLG to maintain the original electrical behavior.

Q: What compliance advantages do the substitute parts offer?

A: Both MKP1V240RLG and K2400E70 are ROHS3 compliant, whereas the original MKP1V240RL is non-compliant. This compliance status is relevant for applications subject to RoHS regulations in the EU and other jurisdictions.

Q: Can the axial package MKP1V240RLG be used in applications designed for TO-92 packages?

A: No. Axial and TO-92 packages have different pin configurations and physical dimensions. Package substitution requires circuit board redesign and verification of mechanical fit and electrical routing.
