Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the V20E175PL4B are identified based on strict electrical and mechanical parameter matching. The following key parameters determine substitution eligibility:

• Maximum AC Volts: 175 V
• Maximum DC Volts: 225 V
• Varistor Voltage (Typical): 270 V
• Current - Surge: 10 kA
• Energy: 135 J
• Number of Circuits: 1
• Capacitance @ 1 MHz: 1400 pF
• Operating Temperature Range: -55°C to 85°C
• Mounting Type: Through Hole
• Package / Case: Disc 20mm
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected

All identified substitute parts match these parameters exactly. Substitutes are grouped as parametric equivalents, meaning they provide identical electrical performance and mechanical compatibility within the same product category.

Parameter Comparison

Engineering Selection Recommendations

All three parts—V20E175PL4B, V20E175P, and TMOV20RP175E—are Active products manufactured by Littelfuse Inc. and meet identical electrical and mechanical specifications. Selection between these parts may be based on:

• Inventory availability: V20E175P has 2225 units in stock, TMOV20RP175E has 1146 units, and V20E175PL4B has 856 units.
• Series preference: V20E175PL4B and V20E175P belong to the UltraMOV™ series, while TMOV20RP175E belongs to the TMOV® series.
• Compliance requirements: All parts are ROHS3 Compliant, REACH Unaffected, and carry identical regulatory certifications.

Any of these parts may be selected for direct substitution in applications requiring a 270 V, 10 kA through-hole disc varistor with the specified electrical and thermal characteristics.

Frequently Asked Questions (FAQ)

Q: Can V20E175P be used as a direct substitute for V20E175PL4B?

A: Yes. V20E175P is a parametric equivalent with identical electrical ratings (175 V AC, 225 V DC, 270 V typical varistor voltage, 10 kA surge current), energy rating (135 J), capacitance (1400 pF @ 1 MHz), operating temperature range (-55°C to 85°C), and through-hole disc 20mm package. Both are UltraMOV™ series parts and meet the same compliance standards.

Q: What is the difference between TMOV20RP175E and V20E175PL4B?

A: TMOV20RP175E and V20E175PL4B are parametric equivalents with identical electrical and mechanical specifications. The primary difference is the product series: TMOV20RP175E belongs to the TMOV® series and includes thermal protection features, while V20E175PL4B belongs to the UltraMOV™ series. Both are Active products from Littelfuse Inc. with ROHS3 compliance and identical voltage, current, and package specifications.

Q: Are all three parts compatible with the same PCB footprint?

A: Yes. All three parts use identical through-hole disc 20mm packaging and are mechanically compatible with the same PCB layout and mounting configuration.

Q: Do these parts have the same regulatory compliance?

A: Yes. V20E175PL4B, V20E175P, and TMOV20RP175E are all ROHS3 Compliant, REACH Unaffected, with MSL 1 (Unlimited) moisture sensitivity level and identical ECCN and HTSUS classifications.

Q: Can I mix these part numbers in the same design or assembly?

A: Yes. Since all three parts are parametric equivalents with identical electrical performance, thermal characteristics, and mechanical compatibility, they may be used interchangeably in the same circuit design or assembly process.
