LC7.0A Equivalent & Substitute Parts

Part Overview

The LC7.0A is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Microchip Technology, designed for general-purpose overvoltage protection applications. This through-hole component features a 7V reverse standoff voltage with a 12V maximum clamping voltage at peak pulse current, capable of handling 100A peak pulse current with 1500W peak pulse power dissipation. The part is currently active in production and available in bulk packaging with RoHS non-compliant status. Equivalent and substitute parts are identified to provide alternative sourcing options, accommodate packaging preferences, or address supply chain requirements while maintaining functional compatibility within specified electrical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LC7.0A are identified based on strict electrical parameter compatibility within the TVS diode category. The primary substitution criteria are:

Critical Matching Parameters:

• Voltage - Reverse Standoff (Typ): 7V
• Voltage - Clamping (Max) @ Ipp: 12V
• Current - Peak Pulse (10/1000µs): 100A
• Power - Peak Pulse: 1500W
• Type: Zener, Unidirectional
• Mounting Type: Through Hole
• Applications: General Purpose

Secondary Compatibility Factors:

• Package / Case format (through-hole variants acceptable)
• Operating temperature range (minimum -55°C acceptable; maximum 175°C required)
• Product Status: Active

The LCE7.0A from Littelfuse Inc. is a direct electrical equivalent with identical voltage and current ratings. The LCE6.5A represents a lower voltage standoff alternative suitable for applications with reduced voltage thresholds, maintaining the same peak pulse current and power dissipation capabilities.

Parameter Comparison

Engineering Selection Recommendations

LCE7.0A (Littelfuse Inc.) is the primary direct substitute for LC7.0A. Both parts maintain identical electrical specifications: 7V reverse standoff voltage, 12V clamping voltage, and 100A peak pulse current. The LCE7.0A is ROHS3 compliant, whereas the LC7.0A is RoHS non-compliant. Both parts are active products with through-hole mounting. The LCE7.0A is supplied in Cut Tape packaging and available in DO-201AA, DO-27, and Axial package formats, compared to the LC7.0A's DO-13 (DO-202AA) package. The operating temperature minimum for LCE7.0A is -55°C versus -65°C for LC7.0A; both maintain the 175°C maximum junction temperature.

LCE6.5A (Littelfuse Inc.) is a lower voltage alternative with 6.5V reverse standoff and 11.2V clamping voltage. This substitute is applicable only in applications where the reduced voltage threshold is acceptable. Peak pulse current and power dissipation remain equivalent at 100A and 1500W. LCE6.5A is ROHS3 compliant and available in Cut Tape packaging with DO-201AA, DO-27, and Axial package options.

Selection between these substitutes depends on application voltage requirements, RoHS compliance mandates, packaging format availability, and operating temperature range specifications.

Frequently Asked Questions (FAQ)

Q: Can LCE7.0A directly replace LC7.0A in all applications?

A: LCE7.0A is electrically equivalent to LC7.0A with identical voltage ratings (7V standoff, 12V clamping) and current handling (100A peak pulse). Both are through-hole mounted Zener TVS diodes. Physical package differences exist: LC7.0A uses DO-13 (DO-202AA) while LCE7.0A uses DO-201AA, DO-27, or Axial formats. Verify PCB footprint compatibility before substitution. Operating temperature minimum differs: LCE7.0A operates to -55°C versus LC7.0A's -65°C.

Q: When is LCE6.5A an acceptable substitute?

A: LCE6.5A is suitable only when the application circuit can tolerate a lower voltage threshold. The 6.5V reverse standoff and 11.2V clamping voltage are lower than LC7.0A's 7V and 12V specifications. Peak pulse current and power dissipation remain at 100A and 1500W. Use LCE6.5A only if circuit design permits reduced clamping voltage.

Q: What are the package compatibility considerations?

A: LC7.0A is supplied in DO-13 (DO-202AA) through-hole package. LCE7.0A and LCE6.5A are available in DO-201AA, DO-27, and Axial through-hole packages. These packages have different physical dimensions and lead spacing. PCB footprint verification is required before substitution. Consult package datasheets for exact dimensional specifications.

Q: Are there RoHS compliance differences?

A: LC7.0A is RoHS non-compliant. Both LCE7.0A and LCE6.5A are ROHS3 compliant. If RoHS compliance is a design requirement, select LCE7.0A or LCE6.5A over LC7.0A.

Q: What is the operating temperature range difference?

A: LC7.0A operates from -65°C to 175°C junction temperature. LCE7.0A and LCE6.5A operate from -55°C to 175°C. If the application requires operation below -55°C, LC7.0A is required. For applications within -55°C to 175°C range, both substitute parts are acceptable.

Q: How do packaging formats affect component sourcing?

A: LC7.0A is supplied in Bulk packaging. LCE7.0A and LCE6.5A are supplied in Cut Tape (CT) packaging. Bulk packaging typically suits high-volume manufacturing, while Cut Tape is standard for automated pick-and-place assembly. Verify your procurement and assembly processes support the available packaging format.

Q: Are all three parts suitable for general-purpose applications?

A: Yes. LC7.0A, LCE7.0A, and LCE6.5A are all classified for general-purpose TVS applications. None are designated for power line protection. All three are unidirectional Zener TVS diodes with 1500W peak pulse power rating and 100A peak pulse current capability.
