V20H175PL2B Equivalent & Substitute Parts

Part Overview

The V20H175PL2B is a 270V 10kA disc varistor manufactured by Littelfuse Inc. in the HMOV™ series. This transient voltage suppressor is designed for through-hole mounting applications requiring surge current protection up to 10kA with an energy rating of 180J. The part is currently active in production with 720 units in stock. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, supply chain considerations, or design flexibility needs.

Key Parameters

Substitute Part Grouping Explanation

The V20H175P is identified as a parametric equivalent to the V20H175PL2B based on the following substitution criteria:

All critical electrical parameters are identical: Maximum AC voltage (175V), Maximum DC voltage (225V), varistor voltage range (243V minimum to 297V maximum with 270V typical), surge current capacity (10kA), and energy dissipation (180J). The capacitance specification (1400pF @ 1MHz) and operating temperature range (-55°C to 125°C) are also matched.

Mechanical compatibility is confirmed through identical mounting type (through hole) and package form factor (disc 20mm). Both parts are manufactured by Littelfuse Inc. within the HMOV™ series and maintain the same compliance certifications (ROHS3 Compliant, REACH Unaffected, MSL 1).

Parameter Comparison

Engineering Selection Recommendations

Both the V20H175PL2B and V20H175P are active production parts from Littelfuse Inc. with full compliance to ROHS3 and REACH requirements. Selection between these parts is based on availability and supply chain requirements rather than electrical or mechanical differentiation. The V20H175P offers higher current inventory (1069 units) compared to the V20H175PL2B (720 units), making it suitable for high-volume procurement scenarios. Both parts maintain identical performance specifications and certifications, ensuring direct functional interchangeability in circuit applications.

Frequently Asked Questions (FAQ)

Q: Can V20H175P be used as a direct replacement for V20H175PL2B?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters. They share the same varistor voltage range (243V to 297V typical 270V), surge current rating (10kA), energy dissipation (180J), and disc 20mm through-hole package form factor.

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

A: No. Both parts carry identical certifications: ROHS3 Compliant, REACH Unaffected status, and Moisture Sensitivity Level 1 (Unlimited). They are both active production parts from Littelfuse Inc.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by matching: maximum AC/DC voltage ratings, varistor voltage specifications (minimum, typical, and maximum values), surge current capacity, energy rating, number of circuits, operating temperature range, mounting type, and package form factor. All these parameters are identical between the V20H175PL2B and V20H175P.

Q: Does the package designation affect interchangeability?

A: No. Both parts use the identical disc 20mm through-hole package, ensuring mechanical compatibility in PCB layouts and circuit board designs without modification.

Q: Are there any temperature or environmental operating differences?

A: No. Both parts operate across the identical temperature range of -55°C to 125°C and maintain the same moisture sensitivity classification (MSL 1 - Unlimited).
