Substitute Part Grouping Explanation

Substitution of the TMOV20R115M is determined by strict equivalence across the following electrical and mechanical parameters:

• Varistor Voltage (Typical): 180 V
• Varistor Voltage Range: 162–198 V (Min–Max)
• Maximum AC Volts: 115 V
• Maximum DC Volts: 150 V
• Current - Surge: 10 kA
• Energy Absorption: 52 J
• Number of Circuits: 1
• Capacitance @ 1 MHz: 2400 pF
• Operating Temperature Range: −55 to +85°C
• Mounting Type: Through Hole
• Package / Case: Disc 20mm 3-Lead
• Features: Thermally Protected

The TMOV20RP115M meets all these criteria and is classified as a direct manufacturer substitute. The primary distinction is product status and compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The TMOV20RP115M is the direct functional equivalent of the TMOV20R115M. Both components are manufactured by Littelfuse Inc. within the iTMOV® series and share identical electrical and mechanical specifications across all critical parameters.

The TMOV20RP115M is the preferred selection for new designs and ongoing procurement due to its active product status. Additionally, the TMOV20RP115M carries ROHS3 compliance certification, whereas the TMOV20R115M is RoHS non-compliant. For applications subject to RoHS regulatory requirements, the TMOV20RP115M is the appropriate choice.

Both parts are supplied in bulk packaging and are available in production quantities.

Frequently Asked Questions (FAQ)
