Key Parameters

Substitute Part Grouping Explanation

Substitution for the ERZ-E11A241CS is determined by strict equivalence across the following critical parameters:

• Varistor voltage rating (216 V minimum, 240 V typical, 264 V maximum)
• Surge current capacity (6 kA)
• Energy absorption (84 J)
• Maximum AC and DC voltage ratings (150 V AC, 200 V DC)
• Physical form factor (Through Hole, Disc 13mm)
• Single-circuit configuration
• Operating temperature range (-40°C to 85°C)
• Capacitance specification (620 pF @ 1 kHz)

The ERZ-E11A241 meets all these criteria and is classified as a parametric equivalent. Both parts share the same ZNR® series designation, base product number (ERZ-E11), and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both the ERZ-E11A241CS and ERZ-E11A241 are active production parts from Panasonic Electronic Components with identical electrical and mechanical specifications. Selection between these parts is based on packaging designation and inventory availability rather than functional differences. Both parts carry ROHS3 compliance, REACH unaffected status, and EAR99 export classification, making them suitable for equivalent circuit protection applications across industrial and commercial voltage suppression requirements.

Frequently Asked Questions (FAQ)

Q: Can ERZ-E11A241 directly replace ERZ-E11A241CS in existing designs?

A: Yes. Both parts are parametric equivalents with identical electrical ratings, surge current capacity, energy absorption, and physical dimensions. The difference in part number designation reflects packaging or distribution channel variation only.

Q: What determines if a varistor can substitute for the ERZ-E11A241CS?

A: A substitute must match all critical parameters: 240 V typical varistor voltage (216-264 V range), 6 kA surge current, 84 J energy absorption, 150 V maximum AC, 200 V maximum DC, through-hole mounting, and 13mm disc form factor.

Q: Are there any compliance differences between ERZ-E11A241CS and ERZ-E11A241?

A: No. Both parts share identical RoHS3 compliance, REACH unaffected status, MSL rating of 1 (Unlimited), and EAR99 export classification.

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

A: Both parts operate across -40°C to 85°C ambient temperature range, suitable for standard industrial and commercial applications.

Q: Does capacitance specification affect substitution?

A: Capacitance (620 pF @ 1 kHz) is a measured characteristic of these varistor designs. Equivalent parts must maintain this specification for consistent circuit behavior in high-frequency transient suppression applications.
