Key Parameters

Substitute Part Grouping Explanation

Substitution of the SSM3K15CT(TPL3) is determined by electrical and mechanical compatibility across the following critical parameters:

Electrical Compatibility Criteria:

• Drain-to-Source Voltage (Vdss) must equal or exceed 30V
• Continuous Drain Current (Id) must equal or exceed 100mA
• Power Dissipation (Max) must equal or exceed 100mW
• Rds On (Max) must not exceed 4Ohm at specified conditions
• Gate-Source Voltage (Vgs) rating must accommodate ±20V or greater
• Threshold Voltage (Vgs(th)) must not exceed 1.5V

Mechanical Compatibility Criteria:

• Package / Case must be SC-101 or SOT-883
• Mounting Type must be Surface Mount
• Supplier Device Package must be CST3 or equivalent

Compliance Criteria:

• RoHS compliance status (RoHS3 preferred for active parts)
• Moisture Sensitivity Level (MSL) must be 1 or equivalent

Substitute parts are grouped into two categories: Direct Substitutes (identical electrical and mechanical specifications with active product status) and Similar Substitutes (compatible electrical parameters with minor deviations).

Parameter Comparison

Engineering Selection Recommendations

Direct Substitute (Preferred):

SSM3K15ACT,L3F is the primary direct substitute for SSM3K15CT(TPL3). This part maintains identical electrical specifications (30V Vdss, 100mA Id, 100mW power dissipation) and mechanical compatibility (SC-101/SOT-883 package, surface mount). The SSM3K15ACT,L3F offers improved Rds On performance (3.6Ohm versus 4Ohm) and carries active product status with ROHS3 compliance, ensuring long-term availability and regulatory alignment.

Secondary Substitute (Identical Electrical Characteristics):

SSM3K15CT,L3F provides electrical equivalence to the original part with matching Vdss (30V), Id (100mA), and Rds On (4Ohm) specifications. This part maintains the same package and mounting configuration. Active product status supports continued procurement. This option is suitable when the specific series designation or packaging format of SSM3K15ACT,L3F is not available.

Alternative Substitute (Reduced Voltage Rating):

CEDM7001 TR PBFREE is a compatible alternative from Central Semiconductor Corp with a reduced Vdss rating of 20V. This part meets or exceeds all other electrical requirements: 100mA continuous drain current, 100mW power dissipation, and superior Rds On performance (3Ohm). The CEDM7001 is suitable for applications where the 30V Vdss specification is not a limiting constraint. This part carries ROHS3 compliance and extended operating temperature range (-65°C to 150°C).

Compliance Considerations:

All substitute parts maintain MSL 1 (Unlimited) moisture sensitivity rating. SSM3K15ACT,L3F and CEDM7001 TR PBFREE carry ROHS3 compliance with REACH Unaffected status, providing regulatory assurance for new designs. SSM3K15CT,L3F compliance status is not specified in available documentation.

Frequently Asked Questions (FAQ)

Q: Can SSM3K15ACT,L3F be used as a direct replacement for SSM3K15CT(TPL3)?

A: Yes. SSM3K15ACT,L3F is a direct substitute. Both parts share identical electrical specifications (30V Vdss, 100mA Id, 100mW power dissipation), the same package (SC-101/SOT-883), and surface mount configuration. SSM3K15ACT,L3F offers improved Rds On performance and active product status.

Q: What is the difference between SSM3K15ACT,L3F and SSM3K15CT,L3F?

A: Both parts are Toshiba N-Channel MOSFETs with identical electrical specifications and packaging. The primary difference is packaging format: SSM3K15ACT,L3F is supplied in Tape & Reel (TR), while SSM3K15CT,L3F packaging format is not specified. Both are active products suitable for new designs.

Q: Can CEDM7001 TR PBFREE replace SSM3K15CT(TPL3) in all applications?

A: CEDM7001 TR PBFREE is compatible for applications where the 30V Vdss specification is not a design requirement. This part operates at 20V Vdss and meets all other electrical parameters (100mA Id, 100mW power dissipation, superior Rds On). Applications requiring 30V operation must use SSM3K15ACT,L3F or SSM3K15CT,L3F.

Q: Are all substitute parts RoHS compliant?

A: SSM3K15ACT,L3F and CEDM7001 TR PBFREE carry ROHS3 compliance. SSM3K15CT,L3F RoHS status is not specified in available documentation. For regulatory-sensitive applications, SSM3K15ACT,L3F is the recommended choice.

Q: What is the input capacitance difference between substitute parts?

A: Input capacitance (Ciss) at 3V varies: SSM3K15CT(TPL3) and SSM3K15CT,L3F are 7.8pF, SSM3K15ACT,L3F is 13.5pF, and CEDM7001 TR PBFREE is 9pF. Higher capacitance may affect switching speed in high-frequency applications. For timing-critical circuits, verify capacitance requirements against application specifications.

Q: What is the operating temperature range for each substitute?

A: SSM3K15CT(TPL3), SSM3K15ACT,L3F, and SSM3K15CT,L3F all operate to 150°C junction temperature. CEDM7001 TR PBFREE extends the lower operating limit to -65°C, providing a wider operating temperature range (-65°C to 150°C). Select based on application thermal requirements.

Q: Are all parts available in the same package?

A: Yes. All parts use SC-101 or SOT-883 package designations and are configured for surface mount assembly. Mechanical compatibility is maintained across all substitutes.
