V33ZS5P Equivalent & Substitute Parts

Part Overview

The V33ZS5P is a 33V 1kA disc varistor manufactured by Littelfuse, designed for transient voltage suppression applications. This through-hole component operates across a temperature range of -55°C to 85°C and is ROHS3 compliant. The part is currently active in production with 838 units in stock. Substitute parts are identified when electrical parameters, mechanical form factor, and compliance certifications remain equivalent across different packaging configurations.

Key Parameters

Substitute Part Grouping Explanation

The V33ZT5P is identified as a parametric equivalent to the V33ZS5P based on the following criteria:

Electrical Parameters Match:

• Varistor voltage range: 29.7 V (Min) – 36.3 V (Max)
• Surge current rating: 1 kA
• Energy rating: 6 J
• Maximum AC/DC voltage ratings: 20 V AC / 26 V DC
• Capacitance: 9290 pF @ 1 MHz
• Operating temperature: -55°C to 85°C

Mechanical Compatibility:

• Mounting type: Through Hole
• Package form factor: Disc 14mm
• Number of circuits: 1

Compliance & Certification:

• RoHS3 compliant
• Moisture Sensitivity Level 1
• REACH unaffected
• ECCN: EAR99
• HTSUS: 8533.40.4000

The only difference between these parts is the packaging configuration: V33ZS5P is supplied in Tape & Reel (TR) format, while V33ZT5P is supplied in Cut Tape (CT) format. Both are manufactured by Littelfuse and maintain active product status.

Parameter Comparison

Engineering Selection Recommendations

Both V33ZS5P and V33ZT5P are active Littelfuse products with identical electrical and mechanical specifications. Selection between these parts depends on packaging requirements and supply chain considerations:

V33ZS5P (Tape & Reel): Suitable for high-volume automated assembly processes requiring continuous reel feeding.

V33ZT5P (Cut Tape): Suitable for lower-volume applications, manual assembly, or situations where individual component handling is preferred.

Both parts maintain ROHS3 compliance, unlimited moisture sensitivity rating, and equivalent performance across all specified electrical parameters. Component selection should be based on assembly methodology and inventory availability rather than functional performance differences.

Frequently Asked Questions (FAQ)

Q: Can V33ZT5P replace V33ZS5P in production? A: Yes. Both parts are electrically and mechanically identical. The difference is packaging format: V33ZS5P uses Tape & Reel while V33ZT5P uses Cut Tape. Substitution is valid if your assembly process accommodates the different packaging format.

Q: Are the electrical specifications identical between these parts? A: Yes. Both parts share identical varistor voltage ratings (29.7 V – 36.3 V), surge current (1 kA), energy rating (6 J), and all other electrical parameters listed in the specification table.

Q: Do both parts have the same physical form factor? A: Yes. Both are through-hole mounted disc varistors with 14mm package dimensions and single-circuit configuration.

Q: Are there compliance differences between these parts? A: No. Both parts are ROHS3 compliant, have Moisture Sensitivity Level 1, and share identical REACH and ECCN classifications.

Q: Which part should I select for my application? A: Selection depends on your assembly process. Choose V33ZS5P for automated reel-fed assembly lines. Choose V33ZT5P for manual assembly or lower-volume production runs. Both deliver identical circuit performance.
