Key Parameters

Substitute Part Grouping Explanation

The V47ZC3P has one parametric equivalent: V47ZA3P. Substitution eligibility is determined by the following critical parameters:

• Varistor Voltage (Typical): 47 V
• Current - Surge: 500 A
• Varistor Voltage Range: 42.3 V (Min) to 51.7 V (Max)
• Maximum AC Volts: 30 V
• Maximum DC Volts: 38 V
• Energy Rating: 4.5 J
• Mounting Type: Through Hole
• Package / Case: Disc 10mm
• Operating Temperature Range: -55°C ~ 85°C
• Number of Circuits: 1

The V47ZA3P meets all these specifications identically, differing only in the series designation (ZA vs. ZC). Both parts are manufactured by Littelfuse Inc. and maintain identical electrical and mechanical characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both the V47ZC3P and V47ZA3P are active production components from Littelfuse Inc. with identical electrical performance and mechanical specifications. Selection between these parts should be based on inventory availability and supply chain considerations. The V47ZA3P currently has higher inventory (17935 units) compared to the V47ZC3P (1123 units). Both parts maintain ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for industrial and commercial applications. The series designation difference (ZC vs. ZA) does not affect functional performance or interchangeability.

Frequently Asked Questions (FAQ)

Q: Can V47ZA3P directly replace V47ZC3P in existing designs? A: Yes. Both parts are electrically and mechanically identical, with matching varistor voltage ratings (47V typical), surge current capacity (500A), energy dissipation (4.5J), and through-hole disc 10mm packaging. Direct substitution is supported without circuit modification.

Q: What determines substitution eligibility for these varistors? A: Substitution is valid when the following parameters match: varistor voltage range (42.3V to 51.7V), surge current rating (500A), maximum AC/DC voltage ratings, energy rating (4.5J), mounting type (through hole), package form (disc 10mm), and operating temperature range (-55°C to 85°C).

Q: Are there compliance differences between V47ZC3P and V47ZA3P? A: No. Both parts carry identical ROHS3 compliance, REACH unaffected status, and moisture sensitivity level (MSL 1 - Unlimited). Regulatory and environmental certifications are equivalent.

Q: What is the significance of the series designation (ZC vs. ZA)? A: The series designation indicates internal manufacturing or design revision within Littelfuse's product line. It does not affect electrical performance, mechanical compatibility, or functional characteristics. Both series meet identical specifications for this voltage and current rating.

Q: Should supply availability influence part selection? A: Supply availability is a valid consideration for procurement planning. The V47ZA3P has significantly higher current inventory (17935 units) versus the V47ZC3P (1123 units), which may impact lead times and delivery schedules for high-volume applications.
