Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PI5L200LE is determined by the following critical parameters:

• Channel Configuration: 4-channel switch architecture
• Circuit Type: 2:1 multiplexer/demultiplexer topology
• On-State Resistance: Maximum 12Ohm specification
• Supply Voltage Compatibility: Single supply operation at 3.3V or 5V
• Bandwidth Performance: Minimum 137MHz -3dB bandwidth for 10/100 Base-T operation
• Package Compatibility: 16-pin TSSOP or equivalent surface-mount package
• Operating Temperature Range: -40°C to 85°C minimum
• Compliance: ROHS3 and REACH compliance required

The two qualified substitutes (FSAL200MTCX and TS5L100DBQR) meet these core requirements with variations in specific electrical characteristics that remain within acceptable operating parameters for Ethernet switching applications.

Parameter Comparison

Engineering Selection Recommendations

FSAL200MTCX (onsemi) provides the closest electrical match to the PI5L200LE with identical on-state resistance (12Ohm), matching -3dB bandwidth (137MHz), and identical operating temperature range (-40°C to 85°C). Supply voltage range (3V to 5.5V) encompasses the original 3.3V and 5V specifications. Package format is 16-TSSOP, maintaining PCB layout compatibility. Current product status is Obsolete, requiring inventory verification before design commitment.

TS5L100DBQR (Texas Instruments) offers higher bandwidth performance (350MHz) and meets the 2:1 multiplexer topology requirement. On-state resistance is elevated to 19Ohm, which remains acceptable for Ethernet switching but represents a 58% increase from the original specification. Supply voltage range (6V to 6.5V) does not overlap with the original 3.3V or 5V specifications, requiring circuit redesign for voltage compatibility. Operating temperature range is reduced to 0°C to 70°C. Package format is 16-SSOP, requiring PCB layout modification. Current product status is Last Time Buy, indicating limited availability window.

Both substitutes maintain ROHS3 compliance and REACH unaffected status. Selection depends on supply voltage requirements, operating temperature range, and PCB layout constraints specific to the application.

Frequently Asked Questions (FAQ)

Q: Can FSAL200MTCX directly replace PI5L200LE in existing designs?

A: FSAL200MTCX is electrically compatible with PI5L200LE in applications using 3.3V or 5V supply voltages. Both parts feature identical 12Ohm on-state resistance, 137MHz bandwidth, and -40°C to 85°C operating temperature range. Package format is identical (16-TSSOP), allowing direct PCB substitution without layout modification. Verify component availability before design commitment due to Obsolete product status.

Q: What are the limitations of TS5L100DBQR as a substitute?

A: TS5L100DBQR requires circuit redesign for voltage compatibility, as its 6V to 6.5V supply range does not support the original 3.3V or 5V operation. On-state resistance increases to 19Ohm, affecting signal path impedance. Operating temperature range is limited to 0°C to 70°C, excluding low-temperature operation below 0°C. Package format is 16-SSOP rather than 16-TSSOP, requiring PCB layout modification. Use only when higher bandwidth (350MHz) justifies these trade-offs.

Q: Are package differences between 16-TSSOP and 16-SSOP significant?

A: Yes. 16-TSSOP has 0.173" width (4.40mm), while 16-SSOP has 0.154" width (3.90mm). These are distinct package outlines requiring different PCB footprints. Direct physical substitution is not possible without PCB redesign. Verify footprint compatibility before selecting TS5L100DBQR.

Q: Do all substitutes maintain the same compliance certifications?

A: Yes. PI5L200LE, FSAL200MTCX, and TS5L100DBQR are all ROHS3 compliant and REACH unaffected. Moisture Sensitivity Level (MSL) differs: PI5L200LE and FSAL200MTCX are MSL 1 (Unlimited), while TS5L100DBQR is MSL 2 (1 Year). This affects storage and handling requirements.

Q: Which substitute is recommended for new designs?

A: Selection depends on application requirements. For voltage compatibility with existing 3.3V or 5V supplies and full temperature range operation, FSAL200MTCX is the primary choice. For applications requiring higher bandwidth and able to accommodate 6V to 6.5V supply redesign, TS5L100DBQR offers superior performance. Verify current inventory status with suppliers before committing to production.
