• Current - Surge Capability: 10 kA
• Energy Absorption: 220 J
• Maximum AC Volts: 175 V
• Number of Circuits: 1
• Mounting Type: Through Hole
• Package / Case: Disc 20mm
• Operating Temperature Range: -55°C to +85°C
• Capacitance @ 1 MHz: 1400 pF

The V175LT20CP is a direct electrical and mechanical equivalent of the V175LT20C. Both parts share identical electrical specifications and physical form factor. The primary difference is packaging format and product status.

Parameter Comparison

Engineering Selection Recommendations

The V175LT20CP is the direct substitute for the V175LT20C. Both parts are manufactured by Littelfuse within the C-III series and maintain identical electrical and mechanical specifications across all critical parameters including varistor voltage, surge current rating, energy absorption, and physical form factor.

The V175LT20C is obsolete; the V175LT20CP is active production. Both parts are ROHS3 compliant and carry identical regulatory classifications (ECCN: EAR99, HTSUS: 8533.40.4000).

The only functional difference is packaging format: the V175LT20C is supplied in bulk packaging, while the V175LT20CP is supplied in cut tape format. This distinction affects procurement and assembly processes but does not alter component performance or electrical characteristics.

Frequently Asked Questions (FAQ)

Q: Can the V175LT20CP be used as a direct replacement for the V175LT20C?

A: Yes. The V175LT20CP is electrically and mechanically identical to the V175LT20C. All electrical parameters, physical dimensions, and performance characteristics are equivalent. The parts are interchangeable in circuit design and application.

Q: What is the difference between bulk packaging and cut tape packaging?

A: Bulk packaging supplies components loose or in bulk form, typically for manual assembly or small-volume applications. Cut tape packaging supplies components on continuous tape in individual pockets, suitable for automated pick-and-place assembly equipment. The component itself is identical; only the delivery format differs.

Q: Why is the V175LT20C listed as obsolete?

A: The V175LT20C has been discontinued by the manufacturer. The V175LT20CP remains in active production and serves as the current production equivalent. For new designs and ongoing support, the V175LT20CP should be specified.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts carry identical RoHS3 compliance status, moisture sensitivity level (MSL 1), and regulatory classifications (ECCN: EAR99, HTSUS: 8533.40.4000).

Q: What is the capacitance specification, and why is it relevant?

A: The capacitance at 1 MHz is 1400 pF for both parts. This parameter is relevant for high-frequency circuit applications where varistor capacitance may affect circuit performance or signal integrity. Both parts are identical in this specification.
