V150LC5P Equivalent & Substitute Parts

Part Overview

The V150LC5P is a 240 V, 2.5 kA disc varistor manufactured by Littelfuse Inc., designed for transient voltage suppression applications. This through-hole component operates across a temperature range of -55°C to 85°C and is ROHS3 compliant. The part is currently in active production status with 758 units in stock. Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and supply chain continuity when the primary part becomes unavailable or when design requirements permit parametric alternatives.

Substitute Part Grouping Explanation

Substitute parts for the V150LC5P are identified based on strict parametric equivalence across electrical and mechanical specifications. The substitution criteria are:

Maximum AC Volts: 150 V
Maximum DC Volts: 200 V
Varistor Voltage (Typical): 240 V
Current - Surge: 2.5 kA
Energy: 25 J
Number of Circuits: 1
Capacitance @ 1 MHz: 360 pF
Operating Temperature Range: -55°C to 85°C
Mounting Type: Through Hole
Package / Case: Disc 10mm

Two substitute parts meet these criteria: V150LA5P (Littelfuse Inc.) and V150LA5 (Harris Corporation). Both maintain identical electrical performance and mechanical form factor specifications.

Engineering Selection Recommendations

V150LA5P is the primary substitute for V150LC5P. Both parts are manufactured by Littelfuse Inc., maintain identical electrical and mechanical specifications, and carry ROHS3 compliance with MSL 1 rating. The V150LA5P differs only in series designation (LA vs. LC) and offers significantly higher inventory availability (5893 units vs. 758 units).

V150LA5 (Harris Corporation) is a parametric equivalent that meets all electrical and mechanical requirements. However, this part carries RoHS non-compliance status and MSL 3 rating (168-hour moisture sensitivity), requiring controlled storage and handling conditions. REACH status is vendor-undefined. Selection of V150LA5 should be limited to applications where RoHS compliance is not mandated and moisture sensitivity can be managed within manufacturing processes.

Frequently Asked Questions (FAQ)

Q: Can V150LA5P be used as a direct replacement for V150LC5P?

A: Yes. V150LA5P is a parametric equivalent with identical electrical performance (240 V typical varistor voltage, 2.5 kA surge current, 25 J energy rating) and mechanical specifications (Disc 10mm, through-hole mounting). Both parts are ROHS3 compliant with MSL 1 rating and operate across -55°C to 85°C.

Q: What is the difference between V150LC5P and V150LA5P?

A: The parts differ only in series designation (LC vs. LA). All electrical parameters, mechanical form factor, compliance certifications, and operating characteristics are identical. The primary distinction is inventory availability and manufacturer series classification.

Q: Can V150LA5 (Harris Corporation) replace V150LC5P?

A: V150LA5 meets all electrical and mechanical parametric requirements. However, it is RoHS non-compliant and carries MSL 3 rating (168-hour moisture sensitivity), requiring controlled storage and handling. Use only in applications where RoHS compliance is not required and moisture management is feasible.

Q: What are the key parameters that determine substitutability?

A: Substitutability is determined by: maximum AC/DC voltage ratings, varistor voltage range (216-264 V), surge current (2.5 kA), energy rating (25 J), capacitance (360 pF @ 1 MHz), operating temperature range (-55°C to 85°C), mounting type (through-hole), and package form factor (Disc 10mm).

Q: Are there inventory considerations for these substitutes?

A: V150LA5P has 5893 units in stock compared to 758 units for V150LC5P. V150LA5 has the highest availability at 15479 units. Inventory levels should be evaluated against procurement timelines and supply chain requirements.
