Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the VDRS14T175BSE is determined by the following critical parameters:

• Maximum AC Volts: 175 V (must match)
• Maximum DC Volts: 225 V (must match)
• Varistor Voltage Range: 247.5 V to 302.5 V (minimum to maximum tolerance band)
• Current - Surge: minimum 4.5 kA (equal or greater)
• Mounting Type: Through Hole (must match)
• Operating Temperature Range: -40°C to 85°C (must match or exceed)
• RoHS Compliance: ROHS3 Compliant (must match)

The ERZ-V14D271 (Panasonic Electronic Components) meets these substitution criteria with a varistor voltage of 270 V (within the acceptable range), surge current of 6 kA (exceeds minimum requirement), and identical environmental and compliance specifications.

Parameter Comparison

Engineering Selection Recommendations

The ERZ-V14D271 is qualified as a direct substitute for the VDRS14T175BSE based on the following factors:

• Both parts maintain identical maximum AC and DC voltage ratings (175 V AC, 225 V DC)
• Varistor voltage specifications fall within the acceptable tolerance band for this application
• The ERZ-V14D271 provides higher surge current capacity (6 kA versus 4.5 kA), offering improved transient protection margin
• Energy absorption capability is increased (99 J versus 67 J), providing enhanced overvoltage suppression performance
• Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements
• Operating temperature ranges are identical (-40°C to 85°C)
• Both parts are active products with confirmed inventory availability

Frequently Asked Questions (FAQ)

Q: Can the ERZ-V14D271 be used as a direct replacement for the VDRS14T175BSE?

A: Yes. The ERZ-V14D271 meets all critical electrical and mechanical parameters required for substitution. Varistor voltage, maximum AC/DC ratings, surge current capacity, and environmental specifications are compatible.

Q: What is the difference in package size between these parts?

A: The VDRS14T175BSE uses a 16mm disc package, while the ERZ-V14D271 uses a 15.5mm disc package. Both are through-hole mounted and compatible with standard PCB layouts designed for 16mm disc varistors.

Q: Does the higher surge current rating of the ERZ-V14D271 affect circuit performance?

A: No. The 6 kA surge rating of the ERZ-V14D271 exceeds the 4.5 kA minimum requirement. This provides additional protection margin without affecting normal circuit operation.

Q: Are there any compliance or certification differences?

A: Both parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. No compliance differences exist.

Q: What is the capacitance difference between these parts?

A: The VDRS14T175BSE has 750 pF capacitance at 1 kHz, while the ERZ-V14D271 has 640 pF at 1 kHz. This difference is within acceptable ranges for transient voltage suppression applications.
