Substitute Part Grouping Explanation

Substitute parts for Littelfuse V27ZC4P are grouped strictly by matching critical electrical and mechanical characteristics within the TVS varistor product category. The substitute part listed matches the following criteria: maximum AC/DC voltage ratings, varistor voltage minimum/typical/maximum, peak surge current, joule energy rating, capacitance at 1 MHz, number of circuits, operating temperature, mounting type, package/case dimensions, as well as compliance status including RoHS and REACH. Only parts that meet all these parameters without deviation are included as suitable substitutes.

Parameter Comparison

Engineering Selection Recommendations

Both V27ZC4P and V27ZA4P are active products with ROHS3 compliance and REACH unaffected status. Moisture Sensitivity Level (MSL) is rated at 1 (Unlimited) for both, and ECCN and HTSUS classifications are matched. Selection should be based on product status and compliance fields as provided.

Frequently Asked Questions (FAQ)

Q1: What are the key criteria for substituting transient voltage suppressor (TVS) varistors in this category?
A1: Key criteria include matching maximum AC and DC voltage, varistor voltage range, surge current capability, energy rating, capacitance at specified frequency, number of circuits, operating temperature range, mounting type, and package/case dimensions, as well as compliance status.

Q2: Is the package size and mounting type critical for substitution?
A2: Yes, the substitute part must use the same Disc 14mm through-hole package to ensure mechanical and application compatibility.

Q3: Does the substitute part meet all relevant compliance requirements?
A3: Both the main and substitute parts are ROHS3 compliant, REACH unaffected, and rated MSL 1 (Unlimited).

Q4: Are there any differences in electrical characteristics that affect substitution?
A4: No differences are present; the electrical parameters provided match exactly between V27ZC4P and V27ZA4P.

Q5: Should ECCN and HTSUS codes be considered during selection?
A5: Both parts share the same ECCN (EAR99) and HTSUS (8533.40.4000) codes, ensuring regulatory alignment within this product category.
