Key Parameters

Substitute Part Grouping Explanation

Substitution of the V150LC20B is determined by strict equivalence across the following critical parameters:

• Varistor Voltage Rating: Nominal 229.5 V (216 V minimum to 243 V maximum range)
• Surge Current Capacity: 6.5 kA
• Energy Absorption: 80 J
• Mounting Configuration: Through Hole, Disc 20mm package
• Electrical Performance: Single circuit, 1600 pF capacitance at 1 MHz
• Environmental Compliance: ROHS3 Compliant, MSL 1 (Unlimited)

The V150LC20BP qualifies as a direct substitute based on identical electrical specifications and mechanical form factor. The primary distinction is product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The V150LC20BP is the direct equivalent for V150LC20B applications. Selection should be based on the following factors:

Product Status: The V150LC20B is obsolete. The V150LC20BP maintains active product status with Littelfuse Inc., ensuring continued availability and manufacturer support.

Compliance & Certification: Both parts are ROHS3 Compliant with MSL 1 (Unlimited) moisture sensitivity rating. The V150LC20BP includes REACH Unaffected status, providing additional regulatory documentation for supply chain compliance.

Electrical & Mechanical Equivalence: Identical varistor voltage rating (229.5 V typical), surge current capacity (6.5 kA), energy absorption (80 J), and through-hole disc 20mm package ensure direct functional substitution without circuit redesign.

Packaging Consideration: The V150LC20BP is supplied in bulk packaging, whereas the original part number designation suggests tape-and-reel or alternative packaging. Verify packaging requirements for automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can V150LC20BP be used as a direct replacement for V150LC20B in existing designs?

A: Yes. The V150LC20BP is electrically and mechanically equivalent. All critical parameters—varistor voltage (229.5 V typical), surge current (6.5 kA), energy (80 J), and through-hole disc 20mm package—are identical. No circuit modifications are required.

Q: Why is the V150LC20B listed as obsolete?

A: Product obsolescence is determined by the manufacturer. The V150LC20BP, with identical specifications and active status, is the recommended alternative for new procurement and ongoing system support.

Q: Are there differences in performance between V150LC20B and V150LC20BP?

A: No performance differences exist. Both parts operate within the same varistor voltage range (216 V to 243 V), handle identical surge current (6.5 kA), and absorb the same energy (80 J). Operating temperature range and environmental compliance are identical.

Q: What is the significance of the packaging difference?

A: The V150LC20BP is supplied in bulk packaging. If your assembly process requires tape-and-reel or alternative packaging formats, confirm packaging availability with your supplier. The electrical and mechanical specifications remain unchanged regardless of packaging format.

Q: Are both parts RoHS compliant?

A: Yes. Both V150LC20B and V150LC20BP are ROHS3 Compliant with MSL 1 (Unlimited) rating. The V150LC20BP additionally carries REACH Unaffected status.

Q: What is the varistor voltage tolerance range?

A: Both parts operate within a varistor voltage range of 216 V (minimum) to 243 V (maximum), with a typical rating of 229.5 V. This tolerance band ensures consistent transient suppression performance across the specified operating range.
