ERZ-V09D330CS Equivalent & Substitute Parts

Part Overview

The ERZ-V09D330CS is a 33 V, 1 kA Transient Voltage Suppressor (TVS) varistor manufactured by Panasonic Electronic Components in the ZNR® series. This through-hole disc varistor is designed for transient voltage protection in electronic circuits. The part is currently Active in product status with 759 pieces available in new original inventory. Substitute parts are identified when equivalent electrical and mechanical parameters are required due to inventory constraints, supply chain considerations, or design flexibility within the allowed specification range.

• Varistor Voltage (Typical): 33 V
• Varistor Voltage Range: 30 - 36 V
• Current - Surge: 1 kA
• Maximum AC Volts: 20 V
• Maximum DC Volts: 26 V
• Energy Absorption: 4.8 J
• Capacitance @ 1 kHz: 6300 pF

Mechanical Parameters (Must Match):

• Mounting Type: Through Hole
• Package / Case: Disc 10mm
• Number of Circuits: 1

Compliance Parameters (Must Match):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• Operating Temperature Range: -40°C to 85°C

The substitute part ERZ-V09V330CS meets all specified electrical, mechanical, and compliance requirements and is therefore classified as a parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

The ERZ-V09V330CS is a direct parametric equivalent to the ERZ-V09D330CS. Both parts are manufactured by Panasonic Electronic Components within the ZNR® series and maintain identical electrical specifications, mechanical dimensions, and compliance certifications.

Selection Basis:

Both parts are Active in product status and ROHS3 Compliant. The substitute part ERZ-V09V330CS carries higher inventory availability (7022 pieces) compared to the main part (759 pieces), making it suitable for applications requiring extended supply assurance. The identical operating temperature range (-40°C to 85°C), moisture sensitivity level (MSL 1), and all electrical parameters ensure direct functional interchangeability in circuit applications.

No performance degradation or functional compromise occurs when substituting ERZ-V09V330CS for ERZ-V09D330CS in designs requiring 33 V, 1 kA transient voltage suppression with through-hole disc mounting.

Frequently Asked Questions (FAQ)

Q: Can ERZ-V09V330CS be used as a direct replacement for ERZ-V09D330CS?

A: Yes. The ERZ-V09V330CS is a parametric equivalent with identical electrical specifications, mechanical package dimensions, and compliance certifications. All key parameters including varistor voltage (33 V typical), surge current (1 kA), energy absorption (4.8 J), and operating temperature range (-40°C to 85°C) are equivalent.

Q: Are there any differences in the physical package between these two parts?

A: No. Both parts use identical through-hole disc 10mm packaging. PCB footprint and mounting requirements are identical.

Q: What is the difference between the part numbers ERZ-V09D330CS and ERZ-V09V330CS?

A: The parts share the same base product number (ERZ-V09) and identical electrical specifications. The difference in the middle character (D versus V) indicates a variation code assigned by Panasonic Electronic Components. Both are active products within the ZNR® series with equivalent performance characteristics.

Q: Are both parts RoHS compliant?

A: Yes. Both ERZ-V09D330CS and ERZ-V09V330CS are ROHS3 Compliant with Moisture Sensitivity Level 1 (Unlimited).

Q: Which part should be selected for new designs?

A: Either part is suitable for new designs. Selection may be based on inventory availability, supply chain considerations, or procurement lead times. The ERZ-V09V330CS currently has higher inventory availability (7022 pieces versus 759 pieces).

Q: Do these parts have the same capacitance characteristics?

A: Yes. Both parts have identical capacitance of 6300 pF measured at 1 kHz, which is a critical parameter for transient suppression performance.

Q: What is the maximum continuous voltage rating for these varistors?

A: The maximum DC voltage is 26 V and maximum AC voltage is 20 V for both parts. These ratings must not be exceeded in circuit design.
