Key Parameters

Substitute Part Grouping Explanation

Substitution is based solely on strict equivalence of all listed electrical, mechanical, and compliance parameters. The following parameters were used to determine substitutability: Maximum AC Volts, Maximum DC Volts, Varistor Voltage (Min/Typ/Max), Surge Current Rating, Energy Rating, Capacitance, Number of Circuits, Operating Temperature, Mounting Type, and Package. Compliance parameters, including RoHS and REACH status, must also match. Only those parts that exactly match all provided parameters are grouped as valid substitutes.

Parameter Comparison

Engineering Selection Recommendations

Both ERZ-E14A751SC and ERZ-E14A751S1 are designated as active parts and are ROHS3 compliant and REACH unaffected according to the provided data. For compliance-driven selection, both options fully meet standard environmental and import/export requirements.

Frequently Asked Questions (FAQ)

Q1: What key parameters must match for varistor equivalency?
A1: Maximum AC and DC voltage, varistor voltage range (min/typ/max), surge current rating, energy rating, capacitance, number of circuits, operating temperature, mounting type, package size, and regulatory statuses.

Q2: Are ERZ-E14A751SC and ERZ-E14A751S1 mechanically and electrically compatible?
A2: Yes. Both parts provide full equivalency across all provided electrical and mechanical parameters, including voltage ratings, energy dissipation, capacitance, and footprint.

Q3: Is the package/case form factor identical between these substitute varistors?
A3: Yes. Both are 14mm disc through-hole packages.

Q4: Does the substitute part have the same compliance characteristics?
A4: Yes. Both replacements are ROHS3 compliant and REACH unaffected.

Q5: Can either variant be used in applications requiring the same surge handling and voltage requirements?
A5: Yes. Both meet provided requirements for surge current, voltage, and energy ratings.

Q6: Is there a difference in the number of circuits supported?
A6: No. Both support a single circuit.

Q7: Are there inventory differences provided?
A7: Yes. Availability is as stated in the input, but this does not affect technical substitution.
