Equivalent & Substitute Parts for V07E320

Part Overview

The V07E320 is a 510 V, 1.75 kA Transient Voltage Suppressor (TVS) varistor manufactured by Littelfuse Inc. in the UltraMOV™ series. This component is designed for single-circuit through-hole applications in a 7mm disc package format. The V07E320 is classified as obsolete, making identification of active equivalent parts essential for ongoing design support and procurement continuity.

Engineering Selection Recommendations

V07E320P (Littelfuse Inc.): This part is the direct active equivalent to the obsolete V07E320. It maintains identical electrical specifications, operating temperature range, and package dimensions. V07E320P carries Active product status and ROHS3 compliance. The packaging format is Bulk, providing standard procurement options. This part is the primary recommendation for direct replacement in existing designs.

ERZ-V07D511 (Panasonic Electronic Components): This part meets all core electrical substitution criteria with matching varistor voltage, surge current, and maximum voltage ratings. The ERZ-V07D511 offers higher energy absorption (45 J versus 32 J) and increased capacitance (90 pF versus 65 pF). The package is a through-hole disc format with a larger 8.5mm diameter compared to the 7mm specification of the original part. The operating temperature minimum is -40°C, which is 15°C higher than the V07E320. This part is suitable for applications where PCB layout accommodates the larger package footprint and the reduced low-temperature operating range is acceptable.

Frequently Asked Questions (FAQ)

Q: Can V07E320P be used as a direct replacement for V07E320? A: Yes. V07E320P is the active equivalent part from the same manufacturer with identical electrical and mechanical specifications. The only difference is product status (Active versus Obsolete) and packaging format (Bulk).

Q: What are the key differences between V07E320P and ERZ-V07D511? A: Both parts share identical varistor voltage (510 V typical) and surge current (1.75 kA) ratings. The ERZ-V07D511 provides higher energy absorption (45 J versus 32 J) and higher capacitance (90 pF versus 65 pF). The package diameter is larger (8.5mm versus 7mm), and the minimum operating temperature is -40°C instead of -55°C.

Q: Is the larger 8.5mm package of ERZ-V07D511 compatible with existing PCB layouts designed for 7mm components? A: The larger package diameter may not fit existing through-hole footprints designed for 7mm disc components. PCB layout verification is required before substitution.

Q: Are all substitute parts RoHS3 compliant? A: Yes. V07E320P and ERZ-V07D511 are both ROHS3 compliant, matching the compliance status of the original V07E320.

Q: What is the significance of the higher energy rating in ERZ-V07D511? A: The ERZ-V07D511 is rated for 45 J energy absorption compared to 32 J for the V07E320. This indicates the Panasonic part can dissipate higher transient energy levels within its operating parameters.

Q: Can ERZ-V07D511 be used in applications requiring -55°C minimum operating temperature? A: No. The ERZ-V07D511 minimum operating temperature is -40°C. Applications requiring -55°C operation must use V07E320P or equivalent parts with matching temperature specifications.
