Key Parameters

Substitute Part Grouping Explanation

The V27ZA2P qualifies as a parametric equivalent to the V27ZC2P based on the following criteria:

All electrical parameters are identical: 27V typical varistor voltage, 500A surge current, 2.5J energy rating, and 3850 pF capacitance at 1 MHz. Both parts share identical voltage specifications (24.3V minimum, 29.7V maximum), maximum AC/DC voltage ratings (17V AC, 22V DC), and operating temperature range (-55°C to 85°C). Both components use identical through-hole disc 10mm packaging and maintain the same compliance certifications (ROHS3, REACH Unaffected). The substitution is valid across the ZC and ZA series designations within the Littelfuse varistor product line.

Parameter Comparison

Engineering Selection Recommendations

Both the V27ZC2P and V27ZA2P are active production components from Littelfuse Inc. with identical electrical and mechanical specifications. Selection between these parts is based on availability and supply chain considerations. The V27ZA2P currently has higher inventory availability (4976 units) compared to the V27ZC2P (911 units). Both parts maintain ROHS3 compliance and REACH unaffected status, making them suitable for applications requiring regulatory compliance. The series designation difference (ZC versus ZA) does not affect functional performance or compatibility within the specified application parameters.

Frequently Asked Questions (FAQ)

Q: Can V27ZA2P replace V27ZC2P in existing designs? A: Yes. Both parts are electrically and mechanically identical across all specified parameters, including varistor voltage, surge current rating, energy dissipation, package type, and operating temperature range.

Q: Are there any differences in compliance or certifications? A: No. Both parts carry identical ROHS3 compliance, REACH unaffected status, and moisture sensitivity level (MSL 1 - Unlimited).

Q: What determines the substitution validity? A: Substitution is valid when all electrical parameters (voltage ratings, surge current, energy), mechanical specifications (package, mounting type), and compliance certifications are identical between parts.

Q: Does the series designation (ZC vs ZA) affect performance? A: No. The series designation reflects internal Littelfuse product line organization but does not impact electrical performance or mechanical compatibility.

Q: Are both parts suitable for the same PCB footprint? A: Yes. Both components use identical through-hole disc 10mm packaging and are mechanically interchangeable.
