Substitute Part Grouping Explanation

Substitute parts for the V150LC20APX10 are qualified based on the following critical parameters:

Maximum AC and DC voltage ratings (150 V AC / 200 V DC)
Varistor voltage specification (240 V typical, 216–264 V range)
Surge current capacity (6.5 kA)
Energy absorption capability (80 J)
Physical package format (Disc 20mm through-hole)
Operating temperature range (-55°C to 85°C)
Compliance certifications (ROHS3, REACH Unaffected)

Parts meeting all these parameters are electrically and mechanically interchangeable. Series variations (LC and LA) within the Littelfuse product line maintain identical performance specifications for this voltage and current class.

Engineering Selection Recommendations

All three parts—V150LC20APX10, V150LA20AP, and V150LC20AP—are qualified substitutes with identical electrical and mechanical specifications. Selection among these parts may be based on:

Inventory availability and lead time requirements
Packaging preferences (bulk packaging is standard for all three)
Series preference within the Littelfuse LC and LA product lines
Supply chain considerations

All parts maintain ROHS3 compliance and REACH Unaffected status, meeting environmental and regulatory requirements. No performance degradation occurs when substituting between these parts in applications requiring 240 V varistor protection with 6.5 kA surge capacity.

Frequently Asked Questions (FAQ)

Q: Can V150LA20AP be used as a direct replacement for V150LC20APX10?

A: Yes. Both parts share identical electrical parameters (240 V typical varistor voltage, 6.5 kA surge current, 80 J energy absorption) and physical package specifications (Disc 20mm through-hole). The series designation (LA vs. LC) does not affect functional compatibility.

Q: Are there any differences in operating temperature range between substitute parts?

A: No. All substitute parts operate across the same temperature range of -55°C to 85°C.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. V150LC20APX10, V150LA20AP, and V150LC20AP are all ROHS3 compliant and REACH Unaffected.

Q: What is the significance of the packaging designation "Bulk"?

A: Bulk packaging indicates standard industrial packaging without special protective measures. All three parts use identical bulk packaging, ensuring consistent handling and storage requirements.

Q: Can these parts be used interchangeably in PCB designs?

A: Yes. The identical through-hole disc 20mm package format ensures mechanical and electrical compatibility on printed circuit boards without layout modifications.

Q: What determines substitution eligibility for this varistor category?

A: Substitution is determined by matching voltage ratings (AC/DC maximums and varistor voltage range), surge current capacity, energy absorption, package type, and operating temperature range. All three parts meet these criteria identically.
