Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the V14H385PL2B is determined by strict equivalence across the following critical parameters:

• Varistor Voltage range: 558V (Min) to 682V (Max), with 620V typical
• Surge Current rating: 6.5 kA
• Maximum AC/DC voltage ratings: 385V AC / 505V DC
• Energy dissipation: 175J
• Package configuration: Disc 14mm, Through Hole mounting
• Operating temperature range: -55°C to 125°C
• Number of circuits: 1

The V14H385P meets all substitution criteria as a parametric equivalent within the HMOV™ series.

Parameter Comparison

Engineering Selection Recommendations

Both the V14H385PL2B and V14H385P are Active products from Littelfuse with identical electrical and mechanical specifications. Selection between these parts may be based on inventory availability: V14H385PL2B has 728 units in stock, while V14H385P has 3016 units available. Both parts maintain ROHS3 compliance, REACH unaffected status, and identical regulatory classifications (EAR99, HTSUS 8533.40.4000). The parts are functionally interchangeable for through-hole PCB applications requiring 620V transient voltage suppression at 6.5kA surge current capacity.

Frequently Asked Questions (FAQ)

Q: Can V14H385P be used as a direct replacement for V14H385PL2B?

A: Yes. Both parts are parametric equivalents with identical electrical ratings (620V typical varistor voltage, 6.5kA surge current), identical package configuration (Disc 14mm through-hole), and identical compliance certifications. No circuit redesign is required.

Q: What are the critical parameters that define substitution eligibility?

A: Substitution is valid when the following parameters match: varistor voltage range (558-682V), surge current (6.5kA), maximum AC/DC ratings (385V/505V), energy dissipation (175J), package type (Disc 14mm), mounting method (through-hole), and operating temperature range (-55°C to 125°C).

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

A: No. Both parts are ROHS3 compliant, REACH unaffected, and classified under identical regulatory codes (EAR99, HTSUS 8533.40.4000).

Q: What is the difference between V14H385PL2B and V14H385P?

A: The parts are electrically and mechanically identical. The designation difference reflects packaging or distribution variants within the HMOV™ series, but no functional or performance distinction exists.

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

A: Yes. The identical electrical specifications, package dimensions, and pin configuration allow direct substitution without PCB layout modifications or circuit parameter adjustments.
