Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERZ-E08B201CS is determined by strict equivalence across the following critical parameters:

• Varistor voltage rating (200 V typical, 185–225 V range)
• Surge current capacity (4.6 kA)
• Energy absorption (35 J)
• Maximum AC and DC voltage ratings (130 V AC, 170 V DC)
• Physical package (Disc 10.5mm through-hole)
• Number of circuits (1)
• Capacitance at 1 kHz (390 pF)
• Operating temperature range (-40°C to 85°C)

The identified substitute ERZ-E08A201 meets all these parameters without deviation, qualifying it as a parametric equivalent within the ZNR® series.

Parameter Comparison

Engineering Selection Recommendations

Both ERZ-E08B201CS and ERZ-E08A201 are active production parts manufactured by Panasonic Electronic Components within the ZNR® varistor series. Both parts carry identical ROHS3 compliance, REACH unaffected status, and EAR99 export classification. Selection between these parts may be based on inventory availability, procurement lead time, or supply chain preference, as electrical performance and mechanical compatibility are fully equivalent. Both parts maintain MSL Level 1 (unlimited moisture sensitivity), indicating no special storage or handling requirements.

Frequently Asked Questions (FAQ)

Q: Can ERZ-E08A201 be used as a direct replacement for ERZ-E08B201CS?

A: Yes. ERZ-E08A201 is a parametric equivalent with identical varistor voltage (200 V typical), surge current (4.6 kA), energy absorption (35 J), physical package (Disc 10.5mm), and all electrical specifications. No circuit redesign or board layout modification is required.

Q: Are there any differences in compliance or certifications between these parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry the same ECCN and HTSUS classifications. Moisture sensitivity level and operating temperature ranges are identical.

Q: What determines whether a varistor can substitute for the ERZ-E08B201CS?

A: A substitute must match all critical parameters: 200 V typical varistor voltage (185–225 V range), 4.6 kA surge current, 35 J energy absorption, 130 V maximum AC rating, 170 V maximum DC rating, 390 pF capacitance at 1 kHz, Disc 10.5mm through-hole package, and -40°C to 85°C operating temperature range.

Q: Can I use a varistor with a different package size?

A: No. Package compatibility is a mandatory substitution criterion. The Disc 10.5mm through-hole package is specific to board layout and mounting requirements. Alternative package sizes are not interchangeable.

Q: Is there any performance difference between these parts in transient suppression applications?

A: No. Both parts provide identical transient voltage suppression performance with the same voltage clamping characteristics, surge current handling, and energy absorption capacity.
