Substitute Part Grouping Explanation

Substitution of the V230LC4 is based on strict equivalence across all critical electrical and mechanical parameters. The substitute part V230LC4P maintains identical specifications for voltage suppression performance, surge current handling, energy absorption, and physical form factor. Both parts are Littelfuse LC series varistors with the same disc 7mm package configuration and through-hole mounting design.

The primary substitution criterion is the matching of varistor voltage range (324 V – 396 V typical 360 V), surge current capacity (1.2 kA), and energy rating (20 J). The packaging and mounting type remain constant across all equivalent parts. The key differentiator is product status: V230LC4P is active production, whereas V230LC4 is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The V230LC4P is the direct equivalent for V230LC4 applications. Both parts are ROHS3 compliant and carry identical electrical ratings, making V230LC4P the appropriate selection for new designs and ongoing production support. The V230LC4P maintains active product status with confirmed inventory availability, eliminating supply chain risk associated with the obsolete V230LC4.

Selection between these parts is determined by availability and procurement timeline. For applications currently using V230LC4, transition to V230LC4P requires no circuit redesign or validation, as all functional parameters are identical. The through-hole disc 7mm package ensures direct mechanical compatibility in existing PCB layouts.

Frequently Asked Questions (FAQ)

Q: Can V230LC4P be used as a direct replacement for V230LC4? A: Yes. V230LC4P is electrically and mechanically identical to V230LC4. All voltage ratings, surge current capacity, energy absorption, and physical dimensions match exactly. The parts are interchangeable in circuit design and PCB layout.

Q: What is the primary reason to substitute V230LC4 with V230LC4P? A: V230LC4 is obsolete. V230LC4P is the active production equivalent from Littelfuse Inc., ensuring long-term availability and supply chain continuity.

Q: Are there any compliance or certification differences between these parts? A: No. Both parts are ROHS3 compliant with identical moisture sensitivity levels (MSL 1 – Unlimited). Regulatory and environmental compliance is equivalent.

Q: Will V230LC4P fit the same PCB footprint as V230LC4? A: Yes. Both parts use the same through-hole disc 7mm package configuration. No PCB redesign is required.

Q: What are the critical parameters for varistor substitution? A: Varistor voltage range (324 V – 396 V), surge current rating (1.2 kA), energy absorption (20 J), and package type (disc 7mm through-hole) must remain constant for direct substitution.

Q: Is there any performance difference between V230LC4 and V230LC4P? A: No. Both parts have identical electrical performance specifications. The difference is product lifecycle status only.
