Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the V22ZC2P is determined by strict equivalence across all critical electrical and mechanical parameters. The V22ZA2P qualifies as a direct substitute based on the following criteria:

Electrical Parameters: Identical varistor voltage range (19.8V minimum to 24.2V maximum, 22V typical), surge current rating (500A), maximum AC/DC voltage ratings (14V AC, 18V DC), energy absorption capacity (2J), and capacitance specification (4500 pF @ 1 MHz).

Mechanical Parameters: Identical mounting configuration (through hole), package form factor (disc 10mm), and circuit count (1 circuit).

Environmental & Compliance: Matching operating temperature range (-55°C to 85°C), RoHS3 compliance status, moisture sensitivity level (MSL 1 - Unlimited), and REACH unaffected classification.

The primary distinction between V22ZC2P and V22ZA2P lies in the series designation (ZC versus ZA), reflecting internal manufacturing or design revision differences that do not affect functional performance or compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both V22ZC2P and V22ZA2P are active production components from Littelfuse Inc. with full ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on availability and supply chain considerations. The V22ZA2P currently maintains higher inventory levels (41,277 units) compared to the V22ZC2P (756 units), making it the preferred choice for applications requiring immediate procurement or bulk quantities. Both parts satisfy identical electrical and mechanical requirements for 22V transient voltage suppression circuits with 500A surge capacity and through-hole disc 10mm packaging.

Frequently Asked Questions (FAQ)

Q: Can V22ZA2P be used as a direct replacement for V22ZC2P?

A: Yes. Both parts are manufactured by Littelfuse Inc. and share identical electrical specifications (22V varistor voltage, 500A surge current, 2J energy), mechanical configuration (through-hole disc 10mm), and environmental ratings (-55°C to 85°C operating range). The series designation difference (ZA versus ZC) does not affect functional compatibility.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by equivalence in varistor voltage range (19.8V to 24.2V), surge current rating (500A), maximum AC/DC voltage ratings (14V AC, 18V DC), energy absorption (2J), capacitance (4500 pF @ 1 MHz), mounting type (through hole), package form factor (disc 10mm), and operating temperature range (-55°C to 85°C).

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

A: No. Both V22ZC2P and V22ZA2P carry identical compliance certifications: ROHS3 compliant, REACH unaffected, MSL 1 (Unlimited), and EAR99 ECCN classification.

Q: What is the primary reason to consider V22ZA2P as an alternative?

A: Supply availability. The V22ZA2P maintains significantly higher inventory levels, making it suitable for applications requiring immediate delivery or large-volume procurement without performance or compatibility compromise.

Q: Are these parts suitable for both AC and DC circuit applications?

A: Yes. Both parts are rated for maximum 14V AC and 18V DC operation, with a typical varistor voltage of 22V, making them suitable for transient suppression in mixed AC/DC circuit environments within these voltage specifications.
