Key Parameters

Substitute Part Grouping Explanation

Substitution of the ERZ-E10A201CS is determined by strict equivalence across the following critical parameters:

• Varistor voltage rating (typical value and tolerance band)
• Surge current capacity
• Maximum AC and DC voltage ratings
• Energy absorption capability
• Physical package dimensions and mounting type
• Operating temperature range
• Compliance certifications (ROHS3, REACH status)

The ERZ-E10A201 qualifies as a parametric equivalent because all electrical characteristics, mechanical specifications, and compliance attributes match the main part exactly. Both parts share the same base product number (ERZ-E10), series designation (ZNR®), and manufacturing standards.

Parameter Comparison

Engineering Selection Recommendations

Both the ERZ-E10A201CS and ERZ-E10A201 are active production parts with identical electrical and mechanical specifications. Selection between these parts may be based on packaging format (bulk vs. alternative packaging) and inventory availability. Both parts maintain ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component procurement. The ERZ-E10A201 currently has higher inventory availability (3992 pcs) compared to the ERZ-E10A201CS (707 pcs), which may influence supply chain decisions.

Frequently Asked Questions (FAQ)

Q: Can ERZ-E10A201 be used as a direct replacement for ERZ-E10A201CS?

A: Yes. Both parts are parametric equivalents with identical varistor voltage ratings (200 V typical, 185–225 V range), surge current capacity (4.5 kA), energy absorption (47 J), and physical package specifications (Disc 11.5mm through-hole). All electrical and mechanical parameters match exactly.

Q: What determines if a varistor can substitute for the ERZ-E10A201CS?

A: Substitution requires matching the varistor voltage rating (including tolerance band), surge current capacity, maximum AC/DC voltage ratings, energy absorption capability, package dimensions, mounting type, and operating temperature range. Compliance certifications (ROHS3, REACH) must also align.

Q: Are there differences in packaging between ERZ-E10A201CS and ERZ-E10A201?

A: Both parts use identical Disc 11.5mm through-hole packages. The designation difference (CS suffix) relates to packaging format or distribution channel, not physical or electrical specifications.

Q: Do both parts meet the same compliance standards?

A: Yes. Both ERZ-E10A201CS and ERZ-E10A201 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component use.

Q: What is the operating temperature range for these parts?

A: Both parts operate across −40°C to +85°C (TA), suitable for industrial and commercial temperature environments.
