Key Parameters

Substitute Part Grouping Explanation

The V20H320PL2T has one parametric equivalent: V20H320PL3T1. Substitution is valid based on the following criteria:

Electrical Parameters (Identical):

• Varistor voltage range: 459 V (Min) to 561 V (Max), 510 V (Typical)
• Surge current rating: 10 kA
• Energy dissipation: 320 J
• Maximum AC/DC voltage ratings: 320 V AC / 420 V DC
• Operating temperature: -55°C to 125°C
• Capacitance: 750 pF @ 1 MHz

Mechanical Parameters (Identical):

• Mounting type: Through Hole
• Package form: Disc 20mm
• Number of circuits: 1

Difference:

• Packaging format: V20H320PL2T supplied in Tape & Reel (TR); V20H320PL3T1 supplied in Cut Tape (CT)

Both parts belong to the HMOV™ series and maintain active product status with full RoHS3 compliance and REACH unaffected status.

Parameter Comparison

Engineering Selection Recommendations

Both V20H320PL2T and V20H320PL3T1 are active production parts with identical electrical and mechanical specifications. Selection between these parts is determined by packaging and supply chain requirements:

V20H320PL2T (Tape & Reel): Suitable for high-volume automated assembly operations where continuous reel feeding is required. Current inventory: 691 pcs.

V20H320PL3T1 (Cut Tape): Suitable for lower-volume applications, manual assembly, or when smaller quantity dispensing is preferred. Current inventory: 1782 pcs.

Both parts maintain full RoHS3 compliance and REACH unaffected status, meeting regulatory requirements for industrial and commercial applications. No functional or performance differences exist between the two variants.

Frequently Asked Questions (FAQ)

Q: Can V20H320PL3T1 be used as a direct replacement for V20H320PL2T?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format: V20H320PL2T is supplied in Tape & Reel format, while V20H320PL3T1 is supplied in Cut Tape format. Substitution is valid for any application where the V20H320PL2T is specified.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging supplies components on continuous reels suitable for automated pick-and-place assembly equipment. Cut Tape (CT) packaging supplies components on tape segments, typically used for manual assembly or lower-volume production runs. The component itself is identical.

Q: Are there any electrical performance differences between these parts?

A: No. Both parts have identical varistor voltage ratings (510 V typical), surge current capacity (10 kA), energy dissipation (320 J), and all other electrical parameters. Performance in circuit is equivalent.

Q: Do both parts meet the same compliance standards?

A: Yes. Both V20H320PL2T and V20H320PL3T1 are RoHS3 compliant, REACH unaffected, and carry MSL rating 1 (unlimited moisture sensitivity). They meet identical regulatory requirements.

Q: Which part should I select for my application?

A: Selection depends on your assembly process. For automated high-volume production, use V20H320PL2T (Tape & Reel). For manual assembly or lower volumes, use V20H320PL3T1 (Cut Tape). Both are functionally equivalent.
