MKP9V160RL Equivalent & Substitute Parts

Part Overview

The MKP9V160RL is a SIDAC (Silicon Diode for Alternating Current) thyristor manufactured by onsemi, designed for applications requiring bidirectional thyristor switching in the 150–170V breakover voltage range. This component is classified as obsolete, making identification of active equivalent parts essential for new designs and production continuity. The MKP9V160RL operates with a peak output current of 900 mA and is packaged in the DO-204AL/DO-41 axial format, suitable for through-hole circuit board assembly.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MKP9V160RL is determined by strict equivalence across the following electrical and mechanical parameters:

• Voltage - Breakover: 150–170V (bidirectional symmetry required)
• Current - Breakover: 200 µA maximum
• Current - Hold (Ih): 100 mA maximum
• Current - Peak Output: 900 mA minimum
• Operating Temperature Range: -40°C to 125°C (TJ)
• Package / Case: DO-204AL/DO-41 axial configuration
• Moisture Sensitivity Level: 1 (Unlimited)

The substitute part MKP9V160RLG meets all specified electrical parameters and maintains identical packaging. The primary distinction is product status: MKP9V160RLG is active and manufactured by Littelfuse Inc., whereas the original MKP9V160RL is obsolete.

Engineering Selection Recommendations

The MKP9V160RLG is a direct electrical and mechanical equivalent to the MKP9V160RL. Selection of MKP9V160RLG is justified on the following grounds:

• All electrical parameters (breakover voltage, breakover current, hold current, peak output current, and operating temperature range) are identical.
• Package and case specifications are identical, ensuring direct board-level compatibility.
• MKP9V160RLG maintains active product status with established supply chain availability.
• MKP9V160RLG achieves ROHS3 compliance, whereas the original part is RoHS non-compliant. This distinction is relevant for applications subject to RoHS regulatory requirements.
• Both parts share identical moisture sensitivity classification and ECCN/HTSUS codes.

For applications where RoHS compliance is not a requirement, either part is electrically and mechanically interchangeable. For new designs or production requiring regulatory compliance, MKP9V160RLG is the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Can MKP9V160RLG be used as a direct replacement for MKP9V160RL in existing designs?

A: Yes. MKP9V160RLG is electrically and mechanically equivalent across all specified parameters. The axial DO-204AL/DO-41 package allows direct board-level substitution without circuit modification.

Q: What is the difference between MKP9V160RL and MKP9V160RLG?

A: The primary differences are manufacturer (onsemi vs. Littelfuse Inc.), product status (obsolete vs. active), and RoHS compliance (non-compliant vs. ROHS3 compliant). Electrical and mechanical specifications are identical.

Q: Why is the original MKP9V160RL listed as obsolete?

A: Obsolescence indicates the part is no longer in active production. MKP9V160RLG, manufactured by Littelfuse Inc., is the active equivalent and recommended for new designs and ongoing production.

Q: Are there any package or pinout differences between these parts?

A: No. Both parts use the DO-204AL/DO-41 axial package with identical pinout and mechanical dimensions. No board layout or assembly changes are required.

Q: Does RoHS compliance affect electrical performance?

A: No. RoHS compliance relates to material composition and environmental regulations, not electrical performance. Both parts meet identical electrical specifications.

Q: What is the breakover voltage tolerance for these parts?

A: The specified breakover voltage range is 150–170V for both parts. This range defines the voltage at which the SIDAC transitions to the conducting state.
