Substitute Part Grouping Explanation

Substitution of the CMPT5401 BK PBFREE is determined by electrical and mechanical parameter equivalence. The following criteria establish valid substitution:

Electrical Equivalence Requirements:

• Transistor type must be PNP
• Collector current rating (Ic Max) must be 600 mA
• Collector-emitter breakdown voltage (VCEO) must be 150 V
• Vce saturation characteristics must match: 500mV @ 5mA, 50mA
• Collector cutoff current (ICBO) must be 50 nA
• DC current gain (hFE) minimum must be 60 @ 10mA, 5V
• Transition frequency must be 300 MHz

Mechanical Equivalence Requirements:

• Package type must be SOT-23-3 (TO-236-3, SC-59)
• Mounting type must be Surface Mount

Compliance Requirements:

• RoHS3 compliance required
• Moisture Sensitivity Level 1 (Unlimited)

The identified substitute parts MMBT5401-7-F and MMBT5401Q-7-F from Diodes Incorporated meet all electrical and mechanical equivalence criteria. Differences in packaging format (Cut Tape vs. Tape & Reel) and operating temperature range do not affect functional substitution.

Engineering Selection Recommendations

CMPT5401 BK PBFREE (Primary Part) Select this part when Central Semiconductor Corp sourcing is preferred and bulk packaging is acceptable. This part is Active status and meets all ROHS3 compliance requirements.

MMBT5401-7-F (Substitute - Cut Tape Format) This substitute is suitable for applications requiring Automotive grade qualification and AEC-Q101 certification. The Cut Tape packaging format accommodates moderate volume requirements. Maximum power rating is 300 mW, which is lower than the primary part. Select this part when automotive-grade components are specified and cut tape packaging is compatible with assembly processes.

MMBT5401Q-7-F (Substitute - Tape & Reel Format) This substitute provides Automotive grade qualification and AEC-Q101 certification with Tape & Reel packaging suitable for high-volume production. Maximum power rating matches the primary part at 350 mW. Select this part for high-volume manufacturing environments requiring automotive-grade components and tape & reel delivery format.

All three parts are Active status and ROHS3 compliant. Operating temperature range differences (-65°C to 150°C for CMPT5401 versus -55°C to 150°C for MMBT5401 variants) must be evaluated against specific application requirements.

Frequently Asked Questions (FAQ)

Q: Can MMBT5401-7-F be used in place of CMPT5401 BK PBFREE? A: Yes. Both parts share identical electrical specifications including collector current (600 mA), breakdown voltage (150 V), saturation voltage (500mV @ 5mA, 50mA), current gain (60 @ 10mA, 5V), and transition frequency (300 MHz). Both use SOT-23-3 surface mount packaging. The primary difference is packaging format (Cut Tape vs. Bulk) and automotive qualification. The lower maximum power rating (300 mW vs. 350 mW) must be verified against circuit requirements.

Q: What is the difference between MMBT5401-7-F and MMBT5401Q-7-F? A: Both parts are electrically identical and manufactured by Diodes Incorporated with AEC-Q101 automotive qualification. The primary difference is packaging format: MMBT5401-7-F is supplied in Cut Tape format, while MMBT5401Q-7-F is supplied in Tape & Reel format. MMBT5401Q-7-F has a maximum power rating of 350 mW matching the primary part, while MMBT5401-7-F is rated at 300 mW.

Q: Are the operating temperature ranges compatible? A: The CMPT5401 BK PBFREE operates from -65°C to 150°C, while both MMBT5401 variants operate from -55°C to 150°C. If the application requires operation below -55°C, the CMPT5401 BK PBFREE is required. For applications within the -55°C to 150°C range, all three parts are compatible.

Q: Do all parts meet RoHS compliance? A: Yes. CMPT5401 BK PBFREE, MMBT5401-7-F, and MMBT5401Q-7-F are all ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited).

Q: Which part should be selected for high-volume production? A: MMBT5401Q-7-F in Tape & Reel format is optimized for high-volume manufacturing. It provides automotive-grade qualification, AEC-Q101 certification, and 350 mW power rating in a format compatible with automated assembly equipment.

Q: Can these parts be used interchangeably in existing designs? A: Yes, provided the design does not require operation below -55°C and the power dissipation does not exceed 300 mW for MMBT5401-7-F applications. All three parts are pin-compatible in SOT-23-3 packages and share identical electrical characteristics within the specified operating ranges.
