Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the V150ZC8P is determined by strict equivalence across the following critical parameters:

• Varistor voltage rating (typical value 150 V, range 135–165 V)
• Surge current capacity (4.5 kA minimum)
• Energy absorption capability (20 J minimum)
• Maximum AC and DC voltage ratings (95 V AC, 127 V DC)
• Mounting configuration (through-hole)
• Package form factor (disc 14mm)
• Operating temperature range (−55°C to +85°C)
• Compliance certifications (ROHS3, REACH Unaffected)

The V150ZA8P meets all substitution criteria as a parametric equivalent. Both parts are manufactured by Littelfuse Inc., share identical electrical specifications, and are housed in the same mechanical package. The primary difference is the series designation (ZC versus ZA), which reflects internal design or manufacturing process variations that do not affect functional performance or compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the V150ZC8P and V150ZA8P are Active products with full regulatory compliance (ROHS3 Compliant, REACH Unaffected). Selection between these parts should be based on availability and procurement lead time. The V150ZC8P currently has higher inventory (1125 pcs) compared to the V150ZA8P (903 pcs). Both parts carry identical electrical ratings, thermal specifications, and mechanical dimensions, ensuring direct interchangeability in circuit applications without design modification or re-qualification.

Frequently Asked Questions (FAQ)

Q: Can V150ZA8P be used as a direct replacement for V150ZC8P?

A: Yes. The V150ZA8P is a parametric equivalent with identical electrical specifications, voltage ratings, surge current capacity, energy absorption, operating temperature range, and package form factor. No circuit modifications are required.

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

A: The series designation reflects internal manufacturing or design variations within Littelfuse's product line. Both series meet the same electrical and mechanical specifications for this voltage and current rating.

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

A: No. Both parts are ROHS3 Compliant, REACH Unaffected, and carry identical moisture sensitivity levels (MSL 1 – Unlimited). They are functionally equivalent for regulatory purposes.

Q: Can these varistors be used in AC or DC circuits?

A: Both parts are rated for AC and DC applications. Maximum AC voltage is 95 V and maximum DC voltage is 127 V. Circuit design must ensure operating voltages remain within these limits.

Q: What is the operating temperature range for these parts?

A: Both the V150ZC8P and V150ZA8P operate across −55°C to +85°C ambient temperature range. Performance is maintained throughout this range.

Q: Are these parts suitable for high-frequency applications?

A: Both parts have a capacitance of 1910 pF at 1 MHz. Circuit designers should account for this capacitive behavior when selecting components for high-frequency transient suppression.
