V150LC5 Equivalent & Substitute Parts

Part Overview

The V150LC5 is a 240 V, 2.5 kA varistor manufactured by Littelfuse Inc., designed for transient voltage suppression in through-hole applications. This component features a disc form factor (10mm) and is rated for surge currents up to 2.5 kA with 25 J energy absorption capability. The V150LC5 is classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing system maintenance and new design implementations where this specification is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the V150LC5 is determined by electrical and mechanical parameter equivalence within the Littelfuse LC series varistor family. The primary substitute, V150LC5P, maintains identical electrical specifications across all critical parameters: maximum AC/DC voltage ratings, varistor voltage range (216 V minimum to 264 V maximum), surge current capacity (2.5 kA), energy absorption (25 J), capacitance characteristics, and operating temperature range. The distinction between V150LC5 and V150LC5P is packaging format: the original part uses standard packaging while the substitute uses bulk packaging. Both components share identical through-hole disc form factor (10mm), circuit count (1), and compliance certifications (ROHS3). The V150LC5P is currently in active production status, providing supply continuity for the obsolete V150LC5 specification.

Parameter Comparison

Engineering Selection Recommendations

The V150LC5P is the direct functional equivalent for V150LC5 applications. Selection of V150LC5P is supported by complete electrical parameter equivalence, identical mechanical form factor, and active production status. The V150LC5P maintains ROHS3 compliance and carries the same ECCN (EAR99) and HTSUS (8533.40.4000) classifications as the original part. For new designs or system replacements requiring 240 V varistor protection with 2.5 kA surge capacity in through-hole disc configuration, V150LC5P provides direct substitution with supply availability assurance.

Frequently Asked Questions (FAQ)

Q: Can V150LC5P be used as a direct replacement for V150LC5? A: Yes. V150LC5P is electrically and mechanically equivalent to V150LC5 across all specified parameters. The parts differ only in packaging format (bulk versus standard), with no impact on circuit performance or physical installation.

Q: What is the primary reason for substitution? A: V150LC5 is classified as obsolete. V150LC5P, an active production equivalent, ensures supply continuity and long-term component availability for maintenance and new implementations.

Q: Are there any compliance or certification differences? A: No. Both V150LC5 and V150LC5P carry identical ROHS3 compliance status, ECCN classification (EAR99), and HTSUS code (8533.40.4000).

Q: Does the disc 10mm form factor remain unchanged? A: Yes. Both parts use identical through-hole disc packaging (10mm), ensuring compatibility with existing PCB layouts and mounting hardware.

Q: What electrical parameters must remain constant for substitution? A: Varistor voltage range (216 V to 264 V typical 240 V), maximum AC/DC ratings (150 V AC, 200 V DC), surge current (2.5 kA), energy absorption (25 J), and operating temperature range (-55°C to 85°C) must all match for functional equivalence.

Q: Is inventory availability a consideration? A: V150LC5P is currently in active production with 758 pcs in stock, providing reliable supply compared to the obsolete V150LC5 status.
