Substitute Part Grouping Explanation

The V150LU10AP has two parametric equivalents: V150LS10AP and V150LT10AP. These substitutes are classified as direct electrical and mechanical equivalents based on the following criteria:

Substitution-Determining Parameters:

• Maximum AC Volts: 150 V (identical across all parts)
• Maximum DC Volts: 200 V (identical across all parts)
• Varistor Voltage Range: 216 V (Min) to 264 V (Max) with 240 V typical (identical across all parts)
• Current - Surge: 4.5 kA (identical across all parts)
• Energy Rating: 45 J (identical across all parts)
• Number of Circuits: 1 (identical across all parts)
• Capacitance @ 1 MHz: 800 pF (identical across all parts)
• Operating Temperature Range: -55°C to 85°C (identical across all parts)
• Mounting Type: Through Hole (identical across all parts)
• Package / Case: Disc 14mm (identical across all parts)

The only difference between these parts is the packaging format: V150LU10AP is supplied in Tape & Reel (TR), while V150LS10AP and V150LT10AP are supplied in Cut Tape (CT). All three parts belong to the Littelfuse LU, LS, and LT series respectively and maintain identical electrical performance and physical dimensions.

Parameter Comparison

Engineering Selection Recommendations

All three parts—V150LU10AP, V150LS10AP, and V150LT10AP—are direct substitutes for one another from an electrical and mechanical standpoint. Selection should be based on the following factors:

Packaging Requirements: Choose V150LU10AP (Tape & Reel) for automated assembly processes requiring continuous reel feeding. Select V150LS10AP or V150LT10AP (Cut Tape) for manual assembly, small-batch production, or applications where individual component handling is preferred.

Compliance and Certifications: All three parts maintain identical ROHS3 compliance, REACH unaffected status, and Moisture Sensitivity Level 1 (Unlimited), ensuring regulatory equivalence across all substitution scenarios.

Product Status and Availability: All parts are in active production status. V150LS10AP offers the highest current inventory (2,769 units), followed by V150LU10AP (1,038 units) and V150LT10AP (702 units). Inventory levels may influence sourcing decisions based on lead time and supply chain requirements.

Electrical Performance: No electrical performance differences exist between these parts. All maintain identical voltage ratings, surge current capacity, energy dissipation, and operating temperature specifications.

Frequently Asked Questions (FAQ)

Q: Can V150LS10AP or V150LT10AP be used as direct replacements for V150LU10AP in existing designs?

A: Yes. All three parts are parametric equivalents with identical electrical specifications, voltage ratings, surge current capacity, and physical dimensions. The only difference is packaging format (Tape & Reel versus Cut Tape). If your assembly process accommodates Cut Tape packaging, V150LS10AP and V150LT10AP are direct substitutes.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) packaging?

A: Tape & Reel packaging supplies components on a continuous reel suitable for automated pick-and-place assembly equipment. Cut Tape packaging provides components on tape segments, typically used for manual assembly or lower-volume production runs. Both formats contain the same component with identical specifications.

Q: Are there any thermal or electrical performance differences between V150LU10AP, V150LS10AP, and V150LT10AP?

A: No. All three parts operate identically across the full -55°C to 85°C temperature range and maintain the same 240 V typical varistor voltage, 4.5 kA surge current capacity, and 45 J energy rating.

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

A: Yes. V150LU10AP, V150LS10AP, and V150LT10AP are all ROHS3 compliant, REACH unaffected, and carry Moisture Sensitivity Level 1 (Unlimited). They share identical ECCN (EAR99) and HTSUS (8533.40.4000) classifications.

Q: Which part should I select based on current inventory?

A: V150LS10AP has the highest inventory availability (2,769 units), making it the preferred choice for applications requiring immediate or large-quantity sourcing. V150LU10AP (1,038 units) and V150LT10AP (702 units) are suitable for standard production volumes where packaging format aligns with assembly requirements.

Q: Can these parts be mixed in the same assembly?

A: Yes. Since all three parts are parametric equivalents with identical electrical and mechanical specifications, they can be used interchangeably within the same circuit or assembly without performance impact. Packaging format differences do not affect circuit functionality.
