ERZ-V09V511CS Equivalent & Substitute Parts

Part Overview

The ERZ-V09V511CS is a 510 V, 3.5 kA disc varistor manufactured by Panasonic Electronic Components within the ZNR® series. This transient voltage suppressor is designed for through-hole mounting applications requiring single-circuit overvoltage protection. The part is currently active in production with 961 units in stock. Equivalent substitute parts are identified to provide design flexibility, inventory alternatives, and continuity of supply for applications where the primary part number may be unavailable or where design specifications permit functional interchange.

Substitute Part Grouping Explanation

Substitution of the ERZ-V09V511CS is determined by equivalence across the following critical parameters:

• Varistor Voltage Rating: Minimum 459 V, Typical 510 V, Maximum 561 V
• Surge Current Capacity: 3.5 kA
• Maximum AC/DC Operating Voltages: 320 V AC, 410 V DC
• Energy Absorption: 92 J
• Mounting Configuration: Through Hole
• Package Geometry: Disc 10mm
• Number of Circuits: Single circuit (1)
• Capacitance Specification: 210 pF @ 1 kHz
• Temperature Operating Range: -40°C to 85°C

The substitute part ERZ-V10D511 maintains identical electrical performance across all specified parameters and is mechanically compatible with the same mounting footprint and package dimensions. Both parts are manufactured by Panasonic Electronic Components within the ZNR® series and comply with ROHS3 and REACH requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the ERZ-V09V511CS and ERZ-V10D511 are active production parts manufactured by Panasonic Electronic Components and are fully compliant with ROHS3 and REACH regulations. The parts are classified under ECCN EAR99 and share identical HTSUS commodity codes.

Selection between these parts should be based on inventory availability and supply chain considerations. The ERZ-V10D511 currently maintains higher inventory levels (3527 units) compared to the ERZ-V09V511CS (961 units), which may influence procurement decisions for high-volume applications or extended lead-time mitigation strategies.

Both parts satisfy identical electrical and mechanical requirements for 510 V, 3.5 kA transient voltage suppression applications with through-hole disc mounting in 10mm package geometry. No performance trade-offs exist between the two part numbers.

Frequently Asked Questions (FAQ)

Q: Are ERZ-V09V511CS and ERZ-V10D511 electrically interchangeable?

A: Yes. Both parts are specified with identical varistor voltage ratings (459 V minimum, 510 V typical, 561 V maximum), surge current capacity (3.5 kA), energy absorption (92 J), and capacitance (210 pF @ 1 kHz). All electrical parameters match across the full operating temperature range of -40°C to 85°C.

Q: Can these parts be used interchangeably in PCB designs?

A: Yes. Both parts feature identical through-hole mounting configuration and disc 10mm package geometry. No PCB layout modifications are required when substituting between ERZ-V09V511CS and ERZ-V10D511.

Q: What are the key parameters that define substitution eligibility?

A: Substitution is determined by matching varistor voltage rating (510 V typical), surge current capacity (3.5 kA), maximum AC/DC operating voltages (320 V AC / 410 V DC), energy absorption (92 J), mounting type (through hole), package dimensions (disc 10mm), and single-circuit configuration. All these parameters are identical between the two parts.

Q: Are both parts compliant with environmental and trade regulations?

A: Yes. Both ERZ-V09V511CS and ERZ-V10D511 are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Both share the same HTSUS commodity code (8533.40.4000).

Q: What is the difference between the ERZ-V09 and ERZ-V10 base product numbers?

A: The base product numbers (ERZ-V09 and ERZ-V10) represent different internal design variants within the Panasonic ZNR® varistor series. Despite different base designations, the ERZ-V09V511CS and ERZ-V10D511 are electrically and mechanically equivalent for the 510 V, 3.5 kA specification.

Q: Which part should be selected for new designs?

A: Both parts are active production items suitable for new designs. Selection may be influenced by current inventory availability, supplier stock levels, or established supply chain relationships. The ERZ-V10D511 currently maintains higher inventory (3527 units) compared to ERZ-V09V511CS (961 units).
