Key Parameters

Substitute Part Grouping Explanation

Substitution is determined strictly by the following key parameters, which must match between the SCHURTER Inc. 0070.1421.T2 and any potential replacements:

• Maximum AC Volts (14 V)
• Maximum DC Volts (18 V)
• Varistor Voltage Range (20 V min, 22 V typ, 24 V max)
• Current - Surge (500 A)
• Energy (1.3J)
• Number of Circuits (1)
• Mounting Type (Through Hole)
• Package / Case dimensions
• Capacitance at Frequency
• Operating Temperature Range
• Lead-free/RoHS and REACH compliance where specified

A qualifying substitute must fully conform to these parameters.

Parameter Comparison

Engineering Selection Recommendations

The SCHURTER Inc. 0070.1421.T2 is obsolete and no longer in production, which requires a substitute for applications demanding long-term availability and support. Direct substitute ERZ-V07D220 from Panasonic Electronic Components is in active production, holds the same RoHS3 and REACH status, and matches all critical electrical parameters. Both parts share the same ECCN and HTSUS classifications. The substitute is compliant with relevant environmental directives as indicated.

Frequently Asked Questions (FAQ)

Q1: What substitution criteria are used for SCHURTER Inc. 0070.1421.T2 equivalents?
A1: Substitution is determined by matching maximum AC/DC voltage ratings, varistor voltage range, surge current, energy rating, number of circuits, mounting type, package/case size, operating temperature, and environmental compliance.

Q2: Is the capacitance difference between 0070.1421.T2 and ERZ-V07D220 relevant for substitution?
A2: Capacitance at 1 kHz is provided for both; differences are noted, but key substitution is governed by the main voltage, current, and package parameters as specified.

Q3: Are the package or case details critical for replacement?
A3: The original part specifies a Disc 7mm package, while the substitute is listed as Disc 8.5mm. Both have through-hole mounting. Mechanical compatibility must be confirmed according to the specified package/case information.

Q4: Are both parts compliant with RoHS3 and REACH regulations?
A4: Both 0070.1421.T2 and ERZ-V07D220 are marked as ROHS3 Compliant and REACH Unaffected.

Q5: Is temperature range a limiting factor for substitution?
A5: 0070.1421.T2 supports -40°C ~ 125°C; ERZ-V07D220 supports -40°C ~ 85°C. The application must be within the substitute's maximum operating temperature for correct functionality, as specified.
