Key Parameters

Substitute Part Grouping Explanation

Substitution is defined strictly by parameters that impact electrical and mechanical compatibility in the category of surface-mount varistors. The qualifying parameters are: Maximum AC Volts, Maximum DC Volts, Varistor Voltage (Min/Typ/Max), Current - Surge, Energy rating, Number of Circuits, Operating Temperature, Mounting Type, and Package / Case. Parts selected as substitutes match these critical values, providing equivalent circuit protection and form factor.

Parameter Comparison

Engineering Selection Recommendations

When replacing ERZ-CF2MK151, preference is given to substitute parts with active product status. For compliance requirements, the substitutes ERZ-VF2M151 and B72650M0950K072 are documented as ROHS3 compliant with REACH unaffected status, supporting the selection in regulated environments. The ERZ-VF2M151 offers increased surge current and energy handling compared to the original, while B72650M0950K072 provides a similar energy rating and form factor within the defined parameters.

Frequently Asked Questions (FAQ)

Q1: What defines compatibility when substituting ERZ-CF2MK151?
A1: Compatibility is determined strictly by matching Maximum AC Volts, Maximum DC Volts, Varistor Voltage range, Current - Surge, Energy rating, Number of Circuits, Operating Temperature, Mounting Type, and Package / Case.

Q2: Are the substitute parts compliant with environmental standards?
A2: Both ERZ-VF2M151 and B72650M0950K072 are noted as ROHS3 compliant, with REACH unaffected status.

Q3: Does the substitute selection consider package form factor?
A3: ERZ-VF2M151 matches the 2-SMD, J-Lead type. B72650M0950K072 uses the 3225 (8063 Metric) case; verify mechanical fit within the specified form factor parameters.

Q4: Why should the obsolete status of ERZ-CF2MK151 prompt a substitution?
A4: Obsolete status limits availability and future support, prompting the selection of active models that match the key electrical and mechanical parameters.

Q5: Can substitutes with higher surge current or energy ratings be used?
A5: Substitute parts with equal or greater surge current and energy ratings are acceptable, contingent on all other parameters matching exactly.

Q6: Is moisture sensitivity level relevant for these substitutions?
A6: ERZ-CF2MK151 and B72650M0950K072 are assigned MSL 1 (unlimited), confirming suitability for standard soldering processes.

Q7: Do the electrical specifications differ between main and substitute parts?
A7: Substitutes ERZ-VF2M151 and B72650M0950K072 match core electrical values; Refer to the parameter comparison table for specific values.
