Substitute Part Grouping Explanation

Substitute parts for the CMPT3019 BK PBFREE are qualified based on the following criteria:

Electrical Compatibility Requirements:

• Transistor Type: NPN
• Voltage - Collector Emitter Breakdown (Max): 80 V minimum
• Current - Collector (Ic) (Max): 500 mA minimum
• Power - Max: 300 mW or greater
• DC Current Gain (hFE) (Min): 100 or greater
• Operating Temperature Range: -55°C to 150°C minimum

Mechanical Compatibility Requirements:

• Package / Case: SOT-23-3 (TO-236-3, SC-59)
• Mounting Type: Surface Mount

Compliance Requirements:

• RoHS Status: ROHS3 Compliant
• Product Status: Active

The three substitute parts identified—MMBTA06-7-F, MMBTA06Q-7-F, and MMBT8099LT1G—meet all electrical and mechanical compatibility criteria. Variations in transition frequency, power dissipation, and saturation voltage characteristics remain within acceptable ranges for general-purpose NPN switching applications.

Engineering Selection Recommendations

MMBTA06-7-F (Diodes Incorporated)

This substitute meets all core electrical and mechanical requirements. It provides 300 mW power dissipation, which is lower than the CMPT3019 BK PBFREE but sufficient for standard switching applications. The 100 MHz transition frequency is adequate for general-purpose use. ROHS3 compliance and Active product status confirm suitability for current designs. Operating temperature range of -55 to 150°C covers most industrial applications, with the exception of extended low-temperature operation below -55°C.

MMBTA06Q-7-F (Diodes Incorporated)

This automotive-grade substitute is qualified to AEC-Q101 standard and maintains 350 mW power dissipation matching the original part. It is suitable for applications requiring automotive-grade reliability and traceability. All electrical parameters meet or exceed minimum requirements. ROHS3 compliance and Active status are confirmed. Operating temperature range is -55 to 150°C.

MMBT8099LT1G (onsemi)

This manufacturer-recommended substitute provides 150 MHz transition frequency and 225 mW power dissipation. While power dissipation is lower, it remains within acceptable limits for general-purpose switching. ROHS3 compliance and Active product status are confirmed. Operating temperature range is -55 to 150°C. This part is supplied in Tape & Reel packaging format.

All three substitutes are Active products with ROHS3 compliance, REACH unaffected status, and EAR99 ECCN classification, matching the regulatory profile of the original part.

Frequently Asked Questions (FAQ)

Q: Can MMBTA06-7-F replace CMPT3019 BK PBFREE in all applications?

A: MMBTA06-7-F meets all core electrical specifications (80 V, 500 mA, 100 MHz) and uses identical SOT-23-3 packaging. The primary difference is 300 mW versus 350 mW power dissipation. Applications operating at maximum power levels may require thermal analysis to confirm suitability.

Q: What is the difference between MMBTA06-7-F and MMBTA06Q-7-F?

A: MMBTA06Q-7-F is automotive-grade (AEC-Q101 qualified) with 350 mW power dissipation, while MMBTA06-7-F is standard-grade with 300 mW. Both use SOT-23-3 packaging and meet 80 V, 500 mA specifications. Select MMBTA06Q-7-F for automotive or high-reliability applications.

Q: Why does MMBT8099LT1G have lower power dissipation (225 mW)?

A: MMBT8099LT1G is a different device variant with different internal characteristics. Despite lower power rating, it meets the 80 V, 500 mA core requirements and is suitable for general-purpose switching. Applications requiring sustained high power operation should use MMBTA06Q-7-F or verify thermal performance.

Q: Are all substitutes available in the same packaging format?

A: All substitutes use SOT-23-3 (TO-236-3, SC-59) Surface Mount packaging. MMBTA06-7-F and MMBTA06Q-7-F are supplied in Cut Tape (CT) & Digi-Reel® format. MMBT8099LT1G is supplied in Tape & Reel (TR) format. Packaging format does not affect electrical compatibility.

Q: What is the operating temperature difference between CMPT3019 BK PBFREE and the substitutes?

A: CMPT3019 BK PBFREE operates from -65°C to 150°C, while all three substitutes operate from -55°C to 150°C. Applications requiring operation below -55°C must use the original CMPT3019 BK PBFREE part.

Q: Are all substitutes RoHS3 compliant?

A: Yes. CMPT3019 BK PBFREE, MMBTA06-7-F, MMBTA06Q-7-F, and MMBT8099LT1G are all ROHS3 compliant with REACH unaffected status.
