V8ZC05P Equivalent & Substitute Parts

Part Overview

The V8ZC05P is an 8.5 V, 50 A Transient Voltage Suppressor (TVS) varistor manufactured by Littelfuse Inc. in a through-hole disc 5mm package. This component is designed for transient voltage protection in electronic circuits and is currently in active production status. Finding equivalent substitute parts is necessary to ensure supply chain flexibility, optimize inventory management, and maintain design continuity when the primary part becomes unavailable or when alternative sourcing is required.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the V8ZC05P are identified based on strict parametric equivalence within the Littelfuse varistor product line. The substitution criteria are limited to the following electrical and mechanical parameters:

• Varistor Voltage Range: 6 V (Min) to 11 V (Max), with 8.5 V typical
• Current - Surge Rating: 50 A
• Maximum DC Volts: 5.5 V
• Maximum AC Volts: 4 V
• Energy Dissipation: 0.1 J
• Mounting Type: Through Hole
• Package / Case: Disc 5mm
• Operating Temperature Range: -55°C ~ 85°C (TA)
• Number of Circuits: 1
• Capacitance @ 1 MHz: 2000 pF

Parts meeting all these parameters are classified as parametric equivalents and may be substituted in applications where the V8ZC05P is specified.

Parameter Comparison

Engineering Selection Recommendations

The V8ZA05P is a direct parametric equivalent to the V8ZC05P. Both parts are manufactured by Littelfuse Inc., share identical electrical specifications, and are housed in the same through-hole disc 5mm package. Both parts maintain active product status and comply with ROHS3 and REACH requirements. The primary distinction between these parts is the series designation (ZC versus ZA), which reflects internal product line organization within Littelfuse but does not affect functional performance or compatibility in circuit applications.

Selection between V8ZC05P and V8ZA05P should be based on availability, lead time, and inventory considerations. Both parts are suitable for direct substitution in applications requiring 8.5 V, 50 A transient voltage suppression with the specified electrical and thermal characteristics.

Frequently Asked Questions (FAQ)

Q: Can the V8ZA05P be used as a direct replacement for the V8ZC05P?

A: Yes. The V8ZA05P meets all parametric requirements for substitution, including varistor voltage range, surge current rating, voltage ratings, energy dissipation, operating temperature range, and package specifications. Both parts are manufactured by Littelfuse Inc. and comply with the same regulatory standards.

Q: What is the difference between the ZC and ZA series designations?

A: The series designation reflects Littelfuse's internal product line organization. From an engineering perspective, both series share identical electrical and mechanical specifications for this voltage and current rating. The series designation does not impact functional performance or circuit compatibility.

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

A: No. Both the V8ZC05P and V8ZA05P carry identical compliance certifications: ROHS3 Compliant, REACH Unaffected, and the same ECCN and HTSUS classifications. Both parts are suitable for applications with equivalent regulatory requirements.

Q: Can these parts be used interchangeably in PCB designs?

A: Yes. Both parts feature identical through-hole disc 5mm packaging and mounting specifications. No PCB layout modifications are required when substituting between V8ZC05P and V8ZA05P.

Q: What parameters must remain constant when selecting a substitute varistor?

A: The critical parameters for substitution are varistor voltage range (6 V to 11 V with 8.5 V typical), surge current rating (50 A), maximum DC and AC voltage ratings (5.5 V DC, 4 V AC), energy dissipation (0.1 J), operating temperature range (-55°C to 85°C), and package type (through-hole disc 5mm). Any deviation from these specifications requires re-evaluation of circuit compatibility.
