Key Parameters

Substitute Part Grouping Explanation

Substitution of the LCE10-B is determined by matching the following critical electrical and mechanical parameters:

• Voltage Rating: Reverse standoff voltage of 10V, breakdown voltage minimum of 11.1V, and clamping voltage maximum of 17V
• Current Handling: Peak pulse current of 88A at 10/1000µs pulse width
• Power Dissipation: Peak pulse power of 1500W
• Package Configuration: DO-201 axial through-hole format
• Device Type: Unidirectional Zener TVS diode with single channel
• Temperature Range: Operating range of -55°C to 175°C (TJ)

The LCE10A meets all these criteria and is therefore a direct electrical and mechanical substitute for the LCE10-B.

Parameter Comparison

Engineering Selection Recommendations

The LCE10A is the direct substitute for the LCE10-B. All electrical parameters, mechanical specifications, and environmental ratings are identical. The LCE10A offers the additional advantage of active product status, ensuring continued availability and supply chain support.

The LCE10A carries ROHS3 compliance, which represents an enhanced regulatory status compared to the LCE10-B's RoHS compliance. Both components maintain MSL Level 1 (Unlimited) moisture sensitivity classification and identical ECCN and HTSUS codes, confirming regulatory equivalence.

The LCE10A is supplied in Cut Tape (CT) packaging with through-hole mounting configuration, providing standard handling and assembly compatibility with existing production processes designed for the LCE10-B.

Frequently Asked Questions (FAQ)

Q: Can the LCE10A be used as a direct replacement for the LCE10-B in existing designs?

A: Yes. The LCE10A is electrically and mechanically identical to the LCE10-B across all specified parameters, including voltage ratings, current handling, power dissipation, operating temperature range, and package format. No design modifications are required.

Q: What is the primary difference between the LCE10-B and LCE10A?

A: The LCE10-B is classified as obsolete, while the LCE10A is an active product. The LCE10A also carries ROHS3 compliance versus RoHS compliance for the LCE10-B. All electrical and mechanical specifications remain identical.

Q: Are there any packaging differences between these parts?

A: Both components use the DO-201 axial package format. The LCE10A is supplied in Cut Tape (CT) packaging, which is standard for through-hole components. The LCE10-B packaging specification was not detailed in the original documentation.

Q: Do these components have the same regulatory certifications?

A: Both parts share identical ECCN (EAR99) and HTSUS (8541.10.0080) classifications. The LCE10A carries ROHS3 compliance, which is an enhanced regulatory status. Both maintain MSL Level 1 (Unlimited) moisture sensitivity classification.

Q: What is the operating temperature range for both components?

A: Both the LCE10-B and LCE10A operate across the identical temperature range of -55°C to 175°C (TJ).

Q: Are these components suitable for the same applications?

A: The LCE10-B was specified for telecom applications. The LCE10A is designated for general purpose applications. Both components possess identical electrical characteristics and can be used interchangeably in circuits requiring 10V reverse standoff TVS protection with 88A peak pulse current capability.
