Engineering Selection Recommendations

VC1206K201R030, ZV30K1206201NIR1, and ZV30K1206T201N are all active status products, ROHS3 compliant, REACH unaffected, and have the same moisture sensitivity level. The main part is qualified to AEC-Q200; for substitutes, qualification data should be aligned with supplied documentation. All listed substitutes match key environmental and compliance certifications as required for equivalent selection.

Frequently Asked Questions (FAQ)

Q1: What determines if a substitute varistor part is equivalent?
A: Substitution is determined by identical maximum AC and DC voltages, varistor voltage range, surge current, energy, and capacitance values, as well as matching operating temperature range, mounting type, package/case, and compliance status.

Q2: Are the mounting and package specifications identical between main and substitute parts?
A: All parts have a surface mount MLCV type and are in a 1206 (3216 Metric) package/case.

Q3: Is qualification level important for automotive applications?
A: Yes. The main part, VC1206K201R030, is AEC-Q200 qualified and designated for automotive grade; substitutes must be checked for equivalent qualification where required.

Q4: What compliance certifications do these varistors provide?
A: All listed parts are ROHS3 compliant, REACH unaffected, and have Moisture Sensitivity Level (MSL) 1 (Unlimited).
