V150LT20B Equivalent & Substitute Parts

Part Overview

The V150LT20B is a 229.5 V disc varistor manufactured by Littelfuse Inc., rated for 6.5 kA surge current with 80 J energy absorption capacity. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement. The part operates across a temperature range of -55°C to 85°C and is packaged as a through-hole disc measuring 20 mm. ROHS3 compliance and unlimited moisture sensitivity level (MSL 1) ensure compatibility with modern manufacturing standards.

Substitute Part Grouping Explanation

Substitution of the V150LT20B is determined by electrical and mechanical parameter equivalence. All substitute parts maintain identical specifications across the following critical parameters: varistor voltage range (216 V – 243 V typical 229.5 V), surge current rating (6.5 kA), energy absorption (80 J), maximum AC/DC voltage ratings (150 V AC / 200 V DC), operating temperature range (-55°C to 85°C), capacitance (1600 pF @ 1 MHz), mounting type (through hole), and package form factor (disc 20 mm). All substitutes are ROHS3 compliant with MSL 1 rating.

Substitutes are differentiated by series designation (LT, LS, LU) and packaging configuration (bulk or tape & reel with quantity multipliers). Series variations represent different manufacturing lines within Littelfuse's varistor portfolio, while packaging designations (BP, BPX10, BPX2855) indicate tape & reel configurations with different reel quantities. The primary substitute V150LT20BP differs from the main part only in packaging format (tape & reel versus bulk) and product status (active versus obsolete).

Engineering Selection Recommendations

All listed substitute parts maintain full electrical and mechanical equivalence to the V150LT20B. Selection among active alternatives should prioritize product status and long-term availability. The V150LT20BP represents the direct successor to the obsolete V150LT20B, sharing identical series designation (LT) and differing only in packaging format and active product status.

For applications requiring tape & reel packaging, V150LT20BPX10 and V150LT20BPX2855 provide the same LT series with different reel configurations. The LS series variants (V150LS20BP, V150LS20BPX10, V150LS20BPX2855) and LU series variants (V150LU20BP, V150LU20BPX10, V150LU20BPX2855) are parametrically equivalent and maintain ROHS3 compliance and REACH unaffected status. All substitutes carry unlimited moisture sensitivity level (MSL 1), ensuring compatibility with standard PCB assembly processes.

Frequently Asked Questions (FAQ)

Q: Can V150LT20BP directly replace V150LT20B in existing designs? A: Yes. V150LT20BP is electrically and mechanically identical to V150LT20B. The primary difference is packaging format (tape & reel versus bulk) and active product status. Through-hole mounting, disc 20 mm form factor, and all electrical parameters remain unchanged.

Q: What is the difference between LT, LS, and LU series variants? A: Series designations represent different manufacturing lines within Littelfuse's varistor portfolio. All three series maintain identical electrical specifications for the V150 229.5 V 6.5 kA rating. Selection between series is based on availability and packaging requirements rather than electrical performance.

Q: Are the BPX10 and BPX2855 packaging variants electrically equivalent? A: Yes. The X10 and X2855 suffixes indicate tape & reel packaging with different reel quantities. Electrical and mechanical specifications are identical across all packaging configurations. Selection depends on procurement volume and supply chain requirements.

Q: Do all substitutes meet the same compliance standards as the original part? A: All active substitute parts are ROHS3 compliant with MSL 1 (unlimited) rating. Substitute parts carry REACH unaffected status, confirming regulatory equivalence for modern manufacturing environments.

Q: Can I use LS or LU series parts in applications originally designed for LT series? A: Yes. All series variants maintain identical electrical parameters: 229.5 V typical varistor voltage, 6.5 kA surge current, 80 J energy absorption, and -55°C to 85°C operating temperature. Through-hole disc 20 mm packaging ensures mechanical compatibility.
