ERZ-E07A511CS Equivalent & Substitute Parts

Part Overview

The ERZ-E07A511CS is a 510 V, 2.5 kA Panasonic ZNR® varistor designed for transient voltage suppression applications. This through-hole disc component (9mm) provides single-circuit overvoltage protection with 70 J energy absorption capability. The part is Active status and widely stocked, making it suitable for immediate deployment in protective circuit designs. Substitute parts may be required due to inventory constraints, regional availability, or specific procurement requirements while maintaining identical electrical and mechanical performance.

Substitute Part Grouping Explanation

Substitution eligibility for the ERZ-E07A511CS is determined by strict equivalence across the following critical parameters:

• Varistor Voltage (Typ): 510 V
• Current - Surge: 2.5 kA
• Maximum AC Volts: 320 V
• Maximum DC Volts: 410 V
• Energy: 70 J
• Mounting Type: Through Hole
• Package / Case: Disc 9mm
• Number of Circuits: 1
• Operating Temperature Range: -40°C to 85°C

Parts meeting all these specifications are classified as parametric equivalents and direct substitutes. The ERZ-E07A511 qualifies as a substitute based on complete parameter alignment with the main part.

Parameter Comparison

Engineering Selection Recommendations

Both the ERZ-E07A511CS and ERZ-E07A511 are Active status components manufactured by Panasonic Electronic Components within the ZNR® varistor series. Both parts carry identical ROHS3 compliance, REACH unaffected status, and MSL 1 rating, confirming regulatory and environmental equivalence. The ERZ-E07A511 offers higher current inventory availability (3702 pcs vs. 1088 pcs), making it suitable for high-volume procurement scenarios. Selection between these parts should be based on supply chain requirements and lead time considerations, as electrical and mechanical performance are identical.

Frequently Asked Questions (FAQ)

Q: Can ERZ-E07A511 be used as a direct replacement for ERZ-E07A511CS?

A: Yes. Both parts are parametric equivalents with identical electrical specifications (510 V typical varistor voltage, 2.5 kA surge current, 70 J energy), mechanical configuration (through-hole disc 9mm), and compliance certifications (ROHS3, REACH unaffected). They are interchangeable in circuit design.

Q: What determines substitution eligibility for this varistor?

A: Substitution is based on exact matching of varistor voltage (510 V typ), surge current rating (2.5 kA), maximum AC/DC voltage limits (320 V / 410 V), energy absorption (70 J), mounting type (through-hole), package form (disc 9mm), and operating temperature range (-40°C to 85°C). Deviation in any of these parameters disqualifies a part as a substitute.

Q: Are there differences in packaging or handling between these parts?

A: Both parts share identical packaging specifications (disc 9mm through-hole) and moisture sensitivity level (MSL 1, unlimited shelf life). No special handling differences apply between the two parts.

Q: Why would I choose one part over the other?

A: Selection is driven by procurement availability. The ERZ-E07A511 maintains higher stock levels, making it preferable for immediate or high-volume orders. The ERZ-E07A511CS may be selected based on specific supplier relationships or regional inventory access. Electrical performance and reliability are equivalent.
