ERZ-E11B751CS Equivalent & Substitute Parts

Part Overview

The ERZ-E11B751CS is a 750 V, 5 kA Panasonic ZNR® varistor designed for transient voltage suppression applications. This through-hole disc component (14mm) provides single-circuit overvoltage protection with 210 J energy absorption capability. The part is Active status and widely used in industrial and consumer electronics for surge protection. Substitute parts are identified when identical electrical and mechanical parameters are maintained across the same product series, ensuring direct interchangeability without circuit redesign.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERZ-E11B751CS is determined by strict equivalence across the following critical parameters:

• Varistor voltage rating (675 V minimum, 750 V typical, 825 V maximum)
• Surge current capacity (5 kA)
• Energy absorption (210 J)
• Package configuration (Disc 14mm, through-hole mounting)
• Number of circuits (1)
• Operating temperature range (-40°C to 85°C)
• Compliance certifications (RoHS3, REACH Unaffected)

Parts meeting all these criteria are classified as parametric equivalents within the ZNR® series and are suitable for direct replacement in existing designs.

Parameter Comparison

Engineering Selection Recommendations

Both ERZ-E11B751CS and ERZ-E11A751 are Active status components manufactured by Panasonic and fully compliant with RoHS3 and REACH regulations. The parts are electrically and mechanically identical across all specified parameters. Selection between these parts may be based on inventory availability: ERZ-E11B751CS has 923 pcs in stock, while ERZ-E11A751 has 1900 pcs available. Both are suitable for direct substitution in 750 V transient voltage suppression applications requiring 5 kA surge capacity and 210 J energy absorption.

Frequently Asked Questions (FAQ)

Q: Can ERZ-E11A751 replace ERZ-E11B751CS in existing designs? A: Yes. Both parts are parametric equivalents with identical electrical ratings (750 V typical, 5 kA surge), energy absorption (210 J), and physical package (Disc 14mm through-hole). No circuit modifications are required.

Q: Are there any compliance differences between these parts? A: No. Both parts carry identical RoHS3 Compliant and REACH Unaffected certifications, with matching ECCN (EAR99) and HTSUS (8533.40.4000) classifications.

Q: What determines substitution eligibility for ZNR® varistors? A: Substitution requires matching varistor voltage rating, surge current capacity, energy absorption, package type, mounting configuration, and operating temperature range. All these parameters must be identical for direct replacement.

Q: Does package size affect interchangeability? A: Yes. Both substitute parts use the same Disc 14mm through-hole package. Any deviation in package type or mounting method would disqualify a part from substitution.

Q: Can these parts be used in AC and DC circuits? A: Yes. Both parts are rated for maximum AC voltage of 460 V and maximum DC voltage of 615 V, making them suitable for mixed-mode protection applications within these voltage limits.
