K2400F2 Equivalent & Substitute Parts

Part Overview

The K2400F2 is a SIDAC thyristor manufactured by Littelfuse, rated for 220–250V breakover voltage with 1A peak output current in a TO-202 Long Tab package. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. The K2400F2 maintains full ROHS3 compliance and operates across the industrial temperature range of –40°C to 125°C.

Key Parameters

Substitute Part Grouping Explanation

The K2400GRP qualifies as a direct manufacturer-recommended substitute for the K2400F2 based on electrical parameter equivalence. Both components share identical electrical specifications: 220–250V breakover voltage, 10 µA breakover current, 150 mA maximum hold current, and 1A peak output current. Both operate across the same temperature range (–40°C to 125°C) and maintain ROHS3 compliance.

The primary difference is packaging: the K2400F2 uses TO-202 Long Tab, while the K2400GRP uses DO-15 (DO-204AC, Axial). This packaging change does not affect electrical performance but requires mechanical redesign of the circuit board layout and component mounting strategy. The K2400GRP is classified as active product status, ensuring long-term availability and supply chain continuity compared to the obsolete K2400F2.

Parameter Comparison

Engineering Selection Recommendations

The K2400GRP is the manufacturer-recommended substitute for the K2400F2. Both components are ROHS3 compliant and share identical electrical performance specifications. Selection of the K2400GRP is appropriate for applications requiring the K2400F2 electrical characteristics, with the understanding that circuit board layout and mechanical mounting must accommodate the DO-15 axial package format instead of the TO-202 Long Tab package.

The active product status of the K2400GRP ensures availability and supply chain stability for ongoing production and new designs, eliminating obsolescence risk associated with the K2400F2.

Frequently Asked Questions (FAQ)

Q: Can the K2400GRP directly replace the K2400F2 without circuit modification?

A: The K2400GRP provides electrical equivalence to the K2400F2. However, the package change from TO-202 Long Tab to DO-15 axial requires mechanical redesign of component mounting and circuit board layout. Electrical circuit modifications are not required.

Q: Are the electrical specifications identical between K2400F2 and K2400GRP?

A: Yes. Both components share identical breakover voltage (220–250V), breakover current (10 µA), maximum hold current (150 mA), peak output current (1 A), and operating temperature range (–40°C to 125°C).

Q: What is the primary reason to transition from K2400F2 to K2400GRP?

A: The K2400F2 is classified as obsolete. The K2400GRP is an active product with guaranteed long-term availability, making it the appropriate choice for new designs and sustained production.

Q: Do both parts maintain the same compliance certifications?

A: Yes. Both the K2400F2 and K2400GRP are ROHS3 compliant and carry the same ECCN (EAR99) and HTSUS (8541.30.0080) classifications.

Q: What packaging considerations apply when using the K2400GRP?

A: The K2400GRP uses DO-15 axial packaging, which differs from the TO-202 Long Tab package of the K2400F2. Circuit board design must accommodate axial lead spacing and mounting orientation appropriate for the DO-15 form factor.
