Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the V20E320PL2T are qualified based on the following critical parameters that determine functional equivalence:

• Varistor voltage rating (typical value 510 V within tolerance range 459 V – 561 V)
• Surge current capacity (10 kA minimum)
• Energy absorption capability (270 J – 273 J)
• Voltage specifications (320 V AC / 420 V DC maximum)
• Thermal operating range (-55°C to 85°C)
• Through-hole mounting configuration with 20mm disc package
• Single circuit configuration
• Capacitance characteristics (750 pF @ 1 MHz)
• Regulatory compliance (ROHS3, REACH Unaffected, EAR99)

All identified substitutes maintain these core electrical and mechanical parameters, ensuring direct replacement capability in existing circuit designs without performance degradation.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain active product status with full ROHS3 compliance and REACH Unaffected certification. Selection between the main part (V20E320PL2T) and substitutes should be based on packaging format availability and inventory requirements:

• V20E320PL2T: Tape & Reel (TR) packaging format
• TMOV20RP320EL2T7: Cut Tape (CT) packaging with thermal protection feature; TMOV® series alternative
• V20E320PL1T: Cut Tape (CT) packaging; UltraMOV™ series variant
• V20E320PL1TX2855: Cut Tape (CT) packaging; UltraMOV™ series variant

All parts are electrically and mechanically equivalent for direct circuit substitution. Energy absorption variance between 270 J and 273 J falls within acceptable tolerance for this component category and does not affect functional performance in specified applications.

Frequently Asked Questions (FAQ)

Q: Can TMOV20RP320EL2T7 replace V20E320PL2T in existing designs?

A: Yes. TMOV20RP320EL2T7 is a parametric equivalent with identical electrical specifications (510 V typical, 10 kA surge current, 320 V AC / 420 V DC maximum). The primary difference is packaging format (Cut Tape vs. Tape & Reel) and series designation (TMOV® vs. UltraMOV™). Both are ROHS3 compliant and suitable for direct replacement.

Q: What is the difference between V20E320PL1T and V20E320PL1TX2855?

A: Both parts are UltraMOV™ series equivalents with identical electrical and mechanical specifications. The difference is in the part number suffix designation (X2855), which typically indicates a specific manufacturing lot or internal tracking code. Electrical performance and compatibility are equivalent.

Q: Does packaging format (Tape & Reel vs. Cut Tape) affect circuit performance?

A: No. Packaging format affects only handling, storage, and assembly processes. Once soldered or mounted, the component performance is identical regardless of original packaging format. Selection should be based on assembly equipment compatibility and inventory management requirements.

Q: Are all substitutes suitable for the same operating temperature range?

A: Yes. All listed substitutes operate across the identical temperature range of -55°C to 85°C. No thermal performance differences exist between the main part and substitutes.

Q: What does the energy rating difference (273 J vs. 270 J) mean for substitution?

A: The 3 J variance between TMOV20RP320EL2T7 (270 J) and other parts (273 J) is within normal manufacturing tolerance for this component category and does not affect functional equivalence or circuit protection capability.
