ESDLC5V0T5-TP Equivalent & Substitute Parts

Part Overview

The ESDLC5V0T5-TP is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Micro Commercial Co, designed for general-purpose overvoltage protection applications. This component features a 5V reverse standoff voltage with a 20V maximum clamping voltage and 5A peak pulse current rating in an SOT-523 surface mount package. The part is currently listed as obsolete, necessitating identification of functionally equivalent alternatives to maintain design continuity and ensure component availability for production and repair applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ESDLC5V0T5-TP is determined by electrical and mechanical compatibility across the following critical parameters:

Electrical compatibility requires matching of the reverse standoff voltage (5V maximum), breakdown voltage range (minimum 5.6V), clamping voltage (20V maximum at peak pulse current), and peak pulse current rating (5A at 8/20µs waveform). The substitute part must maintain the same unidirectional channel configuration (2 channels) and zener diode type classification.

Mechanical compatibility is established through surface mount mounting type and package compatibility. While the ESDLC5V0T5-TP uses SOT-523 packaging, substitute parts may utilize alternative surface mount packages provided they maintain electrical equivalence and are compatible with the application's PCB layout and assembly process.

Compliance requirements include ROHS3 compliance and unlimited moisture sensitivity level (MSL 1), which are met by the identified substitute.

Parameter Comparison

Engineering Selection Recommendations

The ESDSLC5V0T2-TP is the identified direct substitute for the obsolete ESDLC5V0T5-TP. Both components are manufactured by Micro Commercial Co and share identical electrical specifications for reverse standoff voltage, clamping voltage, and peak pulse current. The substitute part maintains ROHS3 compliance and unlimited moisture sensitivity level, meeting the same regulatory and environmental requirements as the original part.

The ESDSLC5V0T2-TP is currently in active production status, ensuring long-term component availability and supply chain continuity. The substitute operates across the same temperature range with a minimum operating temperature of -55°C and maximum of 125°C, compared to the original part's 150°C maximum. Peak pulse power dissipation is rated at 100W versus the original 125W, representing a 20% reduction in power handling capacity.

Package differences exist between the two parts: the original ESDLC5V0T5-TP uses SOT-523 packaging, while the substitute ESDSLC5V0T2-TP uses SOT-23 packaging. This package change requires PCB layout modification and assembly process adjustment but does not affect electrical performance or functional compatibility.

Frequently Asked Questions (FAQ)

Q: What are the key electrical differences between ESDLC5V0T5-TP and ESDSLC5V0T2-TP?

A: The primary electrical difference is the minimum breakdown voltage specification: ESDLC5V0T5-TP specifies 5.6V minimum, while ESDSLC5V0T2-TP specifies 6V minimum. Both parts maintain identical reverse standoff voltage (5V maximum), clamping voltage (20V maximum), and peak pulse current (5A at 8/20µs). Peak pulse power dissipation differs at 125W versus 100W respectively.

Q: Can ESDSLC5V0T2-TP be used as a direct replacement without PCB modification?

A: No. The package change from SOT-523 to SOT-23 requires PCB layout modification. The footprint, pin spacing, and mounting area differ between these packages. Assembly process parameters must be adjusted accordingly.

Q: Are there temperature range limitations when substituting ESDSLC5V0T2-TP?

A: The substitute part operates from -55°C to 125°C, compared to the original part's -55°C to 150°C range. Applications requiring operation above 125°C junction temperature cannot use this substitute without thermal management reassessment.

Q: Do both parts meet the same compliance standards?

A: Yes. Both ESDLC5V0T5-TP and ESDSLC5V0T2-TP are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity level). Both carry REACH unaffected status and EAR99 ECCN classification.

Q: What is the impact of the 25W reduction in peak pulse power rating?

A: The ESDSLC5V0T2-TP's 100W peak pulse power rating versus the original 125W represents a 20% reduction in transient energy dissipation capacity. Applications with peak pulse energy requirements exceeding 100W require alternative component selection or circuit redesign.
