• Power Dissipation: Equal to or greater than 100mW
• On-State Resistance (Rds On): Equal to or less than 3Ohm @ specified conditions
• Gate Threshold Voltage (Vgs(th)): Within acceptable switching range
• Maximum Gate Voltage (Vgs): ±10V or greater

Mechanical Compatibility Requirements:

• Package / Case: SC-101 or SOT-883 (surface mount)
• Mounting Type: Surface Mount
• Supplier Device Package: CST3 or SOT-883

Compliance Requirements:

• RoHS Status: RoHS Compliant or ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Parts meeting these criteria are classified as direct substitutes or similar alternatives based on their electrical performance and product status.

Engineering Selection Recommendations

SSM3K37CT,L3F (Toshiba) — Direct Upgrade Path

The SSM3K37CT,L3F is the recommended primary substitute for the SSM3K16CT(TPL3). This part maintains identical voltage ratings (20V Vdss) and package compatibility (SC-101, SOT-883) while providing enhanced electrical performance. The continuous drain current is doubled to 200mA, and on-state resistance is reduced to 2.2 Ohm @ 100mA, 4.5V, delivering superior current handling and reduced power dissipation in switching applications. The SSM3K37CT,L3F carries Active product status and ROHS3 compliance, ensuring long-term availability and regulatory alignment. This part is suitable for direct replacement in applications where the increased current rating does not create thermal or circuit design conflicts.

CEDM7001 TR PBFREE (Central Semiconductor Corp) — Electrical Equivalent

The CEDM7001 TR PBFREE provides electrical equivalence to the SSM3K16CT(TPL3) with matched drain current (100mA), on-state resistance (3 Ohm @ 10mA, 4V), and power dissipation (100mW). This part is manufactured by Central Semiconductor Corp and maintains identical package compatibility (SC-101, SOT-883). The CEDM7001 TR PBFREE carries Active product status and ROHS3 compliance. The extended operating temperature range (-65°C to 150°C) provides additional thermal margin compared to the main part. This substitute is appropriate for applications requiring direct electrical equivalence without performance enhancement.

Product Status Consideration

The SSM3K16CT(TPL3) is designated "Not For New Designs," indicating discontinued development support from Toshiba. Both substitute parts carry Active status, ensuring ongoing manufacturing support, technical documentation availability, and supply chain continuity. Selection between SSM3K37CT,L3F and CEDM7001 TR PBFREE depends on application requirements: choose SSM3K37CT,L3F for enhanced performance and single-source continuity; choose CEDM7001 TR PBFREE for electrical equivalence and multi-source supply resilience.

Frequently Asked Questions (FAQ)

Q: Can the SSM3K37CT,L3F be used as a direct replacement for the SSM3K16CT(TPL3)?

A: Yes. The SSM3K37CT,L3F is electrically and mechanically compatible. Both devices share identical 20V Vdss rating, SC-101/SOT-883 package, and surface mount configuration. The SSM3K37CT,L3F provides higher continuous drain current (200mA vs. 100mA) and lower on-state resistance (2.2 Ohm vs. 3 Ohm), making it suitable for direct substitution in existing designs. No circuit modifications are required.

Q: What is the difference between SSM3K37CT,L3F and CEDM7001 TR PBFREE?

A: Both parts are compatible substitutes, but differ in manufacturer and performance characteristics. SSM3K37CT,L3F (Toshiba) offers enhanced current handling (200mA) and reduced on-state resistance (2.2 Ohm @ 100mA, 4.5V). CEDM7001 TR PBFREE (Central Semiconductor Corp) matches the original part's electrical specifications (100mA, 3 Ohm @ 10mA, 4V) and provides extended temperature range (-65°C to 150°C). Choose SSM3K37CT,L3F for performance upgrade; choose CEDM7001 TR PBFREE for electrical equivalence.

Q: Are the packages identical between all three parts?

A: Yes. All three parts use SC-101 or SOT-883 surface mount packages. Physical dimensions and PCB footprints are compatible, allowing direct board-level substitution without layout modifications.

Q: Why is the SSM3K16CT(TPL3) marked "Not For New Designs"?

A: This designation indicates that Toshiba has discontinued active development and support for this component. Existing inventory remains available, but the manufacturer recommends using alternative parts for new designs. Both substitute parts carry Active status, ensuring long-term support and supply availability.

Q: What compliance certifications apply to these substitute parts?

A: SSM3K16CT(TPL3) is RoHS Compliant. SSM3K37CT,L3F and CEDM7001 TR PBFREE are both ROHS3 Compliant and REACH Unaffected. All three parts have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Can I use CEDM7001 TR PBFREE in applications requiring higher current than 100mA?

A: No. The CEDM7001 TR PBFREE is rated for 100mA continuous drain current, matching the original SSM3K16CT(TPL3). For applications requiring current above 100mA, use the SSM3K37CT,L3F, which is rated for 200mA continuous drain current.

Q: What is the difference in gate threshold voltage between these parts?

A: SSM3K16CT(TPL3) has Vgs(th) of 1.1V @ 100µA. SSM3K37CT,L3F has Vgs(th) of 1V @ 1mA. CEDM7001 TR PBFREE has Vgs(th) of 900mV @ 250µA. These variations are within acceptable switching ranges for typical applications and do not prevent substitution.

Q: Are there supply chain advantages to using CEDM7001 TR PBFREE?

A: Yes. CEDM7001 TR PBFREE is manufactured by Central Semiconductor Corp, providing a second-source alternative to Toshiba parts. Multi-source availability reduces supply chain risk and may provide cost or lead-time advantages depending on market conditions.
