Substitute Part Grouping Explanation

Substitute parts for the V20H35PL2B are identified based on strict parametric equivalence within the Transient Voltage Suppressors (TVS) category. The substitution criteria are:

• Varistor voltage specification: 56 V (typical), with tolerance range 50.4 V – 61.6 V
• Surge current rating: 5 kA
• Energy dissipation: 115 J
• Maximum AC/DC voltage ratings: 35 V AC, 45 V DC
• Operating temperature range: -55°C to 125°C
• Mounting configuration: Through hole
• Package form factor: Disc 20mm
• Number of circuits: 1

Only parts meeting all these electrical and mechanical parameters are classified as direct substitutes. No performance optimization, feature enhancement, or alternative specifications are considered in this substitution relationship.

Parameter Comparison

Engineering Selection Recommendations

Both the V20H35PL2B and V20H35P are active production components from Littelfuse Inc. with identical electrical specifications and mechanical form factors. Selection between these parts may be based on inventory availability: V20H35PL2B has 811 units in stock, while V20H35P has 2478 units available. Both parts maintain ROHS3 compliance, REACH unaffected status, and MSL 1 rating, ensuring compatibility with standard manufacturing and storage conditions. The parts are functionally interchangeable for all 56 V, 5 kA transient voltage suppression applications within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can V20H35P be used as a direct replacement for V20H35PL2B?

A: Yes. Both parts are electrically and mechanically identical, with matching varistor voltage (56 V), surge current (5 kA), energy rating (115 J), and through-hole disc 20mm package configuration. All electrical parameters, temperature range, and compliance certifications are equivalent.

Q: What are the key parameters that define substitutability for this varistor?

A: Substitutability is determined by: varistor voltage specification (56 V ±10%), surge current rating (5 kA), energy dissipation (115 J), maximum AC/DC voltage ratings (35 V / 45 V), operating temperature range (-55°C to 125°C), and physical package form (through-hole disc 20mm). Deviation in any of these parameters disqualifies a part as a direct substitute.

Q: Are there any compliance or certification differences between these parts?

A: No. Both V20H35PL2B and V20H35P carry identical certifications: ROHS3 compliance, REACH unaffected status, MSL 1 (unlimited moisture sensitivity level), and EAR99 export classification. They are equivalent from a regulatory and environmental standpoint.

Q: What is the difference between V20H35PL2B and V20H35P part numbers?

A: The part numbers differ in their suffix designation, which typically indicates packaging or distribution channel variation within Littelfuse's product line. The electrical and mechanical specifications remain identical, making them functionally interchangeable.

Q: Can these parts be used in both AC and DC circuits?

A: Yes. Both parts are rated for maximum AC voltage of 35 V and maximum DC voltage of 45 V, with operating temperature range from -55°C to 125°C. They are suitable for transient voltage suppression in both AC and DC applications within these voltage limits.
