Substitute Part Grouping Explanation

Substitution eligibility for the V420LS10PX2855 is determined by the following critical parameters:

• Maximum AC Volts: 420 V
• Maximum DC Volts: 560 V
• Varistor Voltage (Typical): 680 V
• Current - Surge: 2.5 kA
• Energy: 55 J
• Number of Circuits: 1
• Operating Temperature Range: -55°C to 85°C
• Mounting Type: Through Hole
• Package / Case: Disc 10mm
• Series: LS

The V420LS10P qualifies as a parametric equivalent because it maintains identical electrical specifications and mechanical form factor. The only difference is packaging format: the main part is supplied in Tape & Reel (TR) configuration, while the substitute is supplied in Cut Tape (CT) configuration. Both parts are manufactured by Littelfuse Inc. within the same LS series and carry identical performance ratings.

Parameter Comparison

Engineering Selection Recommendations

Both the V420LS10PX2855 and V420LS10P are active production components from Littelfuse Inc. with full ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on procurement and assembly requirements:

The V420LS10PX2855 in Tape & Reel format is suitable for high-volume automated assembly operations. The V420LS10P in Cut Tape format accommodates lower-volume applications or manual assembly processes. Both parts deliver identical electrical performance and thermal characteristics across the specified operating range. Inventory availability may influence selection, with 5657 units of V420LS10P currently in stock compared to 661 units of the main part.

Frequently Asked Questions (FAQ)

Q: Can V420LS10P be used as a direct replacement for V420LS10PX2855?

A: Yes. Both parts are electrically and mechanically identical. The difference is packaging format only: Tape & Reel versus Cut Tape. Electrical performance, voltage ratings, surge current capacity, and thermal characteristics are identical.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging is optimized for automated pick-and-place assembly on production lines. Cut Tape (CT) packaging provides individual component strips suitable for manual assembly or lower-volume applications. The component itself is unchanged.

Q: Are both parts ROHS3 compliant?

A: Yes. Both V420LS10PX2855 and V420LS10P carry ROHS3 compliance certification and are REACH unaffected.

Q: What is the operating temperature range for these varistors?

A: Both parts operate across -55°C to 85°C ambient temperature range.

Q: Can these varistors be used in applications requiring different voltage ratings?

A: No. These parts are rated for 420 V maximum AC and 560 V maximum DC. Applications requiring different voltage ratings require alternative varistor models with corresponding voltage specifications.

Q: What is the surge current capacity?

A: Both parts are rated for 2.5 kA surge current with 55 J energy absorption capability.
