Surface mount technology

Electrical Compatibility Criteria:

On-state resistance maximum of 15Ohm (allows equal or lower values)
Supply voltage compatibility with 3.3V operation
Bandwidth minimum of 213MHz (-3dB)
Operating temperature range encompassing or exceeding -40°C ~ 85°C

Engineering Selection Recommendations

Primary Substitutes (Active Product Status):

TS3L100PW and TS3L100PWR are the preferred substitutes for the PI3L100LE. Both parts maintain identical package geometry (16-TSSOP, 0.173" width), supply voltage compatibility (3.3V within 3V ~ 3.6V range), and on-state resistance specification (15Ohm). These Texas Instruments parts are in active production status with unlimited moisture sensitivity rating (MSL 1), ensuring long-term availability and handling flexibility. The expanded bandwidth (350MHz vs. 213MHz) provides performance margin without affecting functional compatibility.

TS3L100DGVR offers equivalent electrical performance with MSL 1 rating but uses a 16-TFSOP package (0.173" width). This variant is suitable for designs where package footprint dimensions are verified as compatible.

Secondary Substitute (Limited Availability):

TS3L100DBQR is an active Texas Instruments product with compatible electrical specifications but uses a 16-SSOP package (0.154" width), requiring PCB layout verification before implementation. MSL 2 rating requires controlled storage conditions (1-year shelf life).

Not Recommended:

TS5L100DBQR operates at 6V ~ 6.5V supply voltage, incompatible with the 3.3V design requirement of the PI3L100LE. This part is in Last Time Buy status and should not be selected for new designs.

All recommended substitutes maintain ROHS3 compliance, EAR99 classification, and REACH unaffected status consistent with the original part.

Frequently Asked Questions (FAQ)

Q: Can TS3L100PW directly replace PI3L100LE without PCB modifications?

A: Yes. TS3L100PW maintains identical 16-TSSOP package dimensions (0.173", 4.40mm width), pin configuration, and electrical specifications. Direct footprint compatibility is confirmed. Supply voltage (3.3V) falls within the TS3L100PW operating range (3V ~ 3.6V).

Q: What is the difference between TS3L100PWR and TS3L100PW?

A: Both parts are electrically and functionally identical. The difference is packaging format: TS3L100PWR is supplied in Tape & Reel (TR) format for automated assembly, while TS3L100PW is supplied in Tube format for manual handling. Select based on assembly process requirements.

Q: Why is TS3L100DBQR not recommended as a primary substitute?

A: TS3L100DBQR uses a 16-SSOP package (0.154", 3.90mm width), which differs from the original 16-TSSOP specification (0.173", 4.40mm width). PCB layout verification is required to confirm footprint compatibility. Additionally, MSL 2 rating requires 1-year shelf life management.

Q: Can TS3L100DGVR be used in place of PI3L100LE?

A: TS3L100DGVR is electrically compatible and maintains MSL 1 rating. However, it uses a 16-TFSOP package. While the width dimension (0.173") matches the original, the TFSOP variant has different pin spacing characteristics. Verify PCB layout compatibility before implementation.

Q: Is TS5L100DBQR a suitable substitute?

A: No. TS5L100DBQR operates at 6V ~ 6.5V supply voltage, which is incompatible with the PI3L100LE design requirement of 3.3V. Additionally, this part is in Last Time Buy status. Do not select for new designs.

Q: What are the key electrical differences between PI3L100LE and its substitutes?

A: The primary difference is bandwidth: PI3L100LE operates at 213MHz, while all Texas Instruments substitutes (TS3L100 series) operate at 350MHz. This represents improved performance margin. On-state resistance remains constant at 15Ohm across all recommended substitutes. Operating temperature range narrows from -40°C ~ 85°C to 0°C ~ 70°C in the TS3L100 series.

Q: Are all recommended substitutes ROHS3 compliant?

A: Yes. All recommended substitute parts (TS3L100PW, TS3L100PWR, TS3L100DGVR, TS3L100DBQR) are ROHS3 compliant with EAR99 classification and REACH unaffected status, matching the original PI3L100LE compliance profile.

Q: What is the moisture sensitivity level (MSL) impact on component handling?

A: PI3L100LE and most recommended substitutes (TS3L100PW, TS3L100PWR, TS3L100DGVR) have MSL 1 rating, allowing unlimited shelf life without special storage conditions. TS3L100DBQR and TS5L100DBQR have MSL 2 rating, requiring storage at controlled humidity and a 1-year shelf life limit from manufacturing date.
