Engineering Selection Recommendations

CPH5520-TL-E (MFR Recommended Substitute)

The CPH5520-TL-E is the manufacturer-recommended substitute for the obsolete CPH5506-TL-E. This onsemi device maintains identical package configuration (SOT-23-5 Thin, TSOT-23-5) and mounting type (Surface Mount). The CPH5520-TL-E exceeds the electrical specifications of the main part with 2A maximum collector current (versus 1.5A), higher voltage ratings (80V, 50V versus 30V), and equivalent power dissipation (1.2W). Both devices share identical DC current gain specifications (200 @ 100mA, 2V) and operating temperature range (150°C TJ). The CPH5520-TL-E is currently in active production status with 12,400 units in stock. This part is ROHS3 compliant with MSL 1 (Unlimited) rating, matching the compliance profile of the original device.

QSZ2TR (Cross-Manufacturer Substitute)

The QSZ2TR manufactured by Rohm Semiconductor provides functional equivalence with identical voltage (30V) and current (1.5A) specifications to the CPH5506-TL-E. This device maintains the same SOT-23-5 Thin package configuration and surface mount mounting type. The QSZ2TR features superior DC current gain (270 @ 100mA, 2V versus 200), marginally higher power rating (1.25W versus 1.2W), and equivalent operating temperature (150°C TJ). The device is currently in active production with 3,011 units in stock. ROHS3 compliance and MSL 1 (Unlimited) rating align with the original part specifications. Transition frequency is lower (300MHz, 280MHz versus 500MHz, 450MHz), which may impact high-frequency applications.

Frequently Asked Questions (FAQ)

Q: Can the CPH5520-TL-E directly replace the CPH5506-TL-E in all applications?

A: The CPH5520-TL-E meets or exceeds all electrical and mechanical specifications of the CPH5506-TL-E. The higher voltage ratings (80V, 50V versus 30V) and increased current capacity (2A versus 1.5A) provide enhanced performance margins. Identical package configuration (SOT-23-5 Thin, TSOT-23-5) and mounting type (Surface Mount) ensure mechanical compatibility. The lower transition frequency (420MHz versus 500MHz, 450MHz) may affect applications requiring maximum high-frequency performance.

Q: What are the key differences between CPH5520-TL-E and QSZ2TR substitutes?

A: Both devices provide functional equivalence to the CPH5506-TL-E with identical voltage (30V) and current (1.5A) ratings. The CPH5520-TL-E is manufactured by onsemi (original manufacturer) with higher transition frequency (420MHz) and is the MFR-recommended substitute. The QSZ2TR is manufactured by Rohm Semiconductor with lower transition frequency (300MHz, 280MHz) but superior DC current gain (270 versus 200). Both maintain identical package and mounting specifications.

Q: Are there packaging differences between the main part and substitutes?

A: All three devices utilize identical package configuration: SOT-23-5 Thin (TSOT-23-5) with surface mount mounting type. The CPH5506-TL-E and CPH5520-TL-E are supplied in Cut Tape (CT) and Tape & Reel (TR) packaging respectively, but the physical component package remains identical. The QSZ2TR is supplied in Cut Tape (CT) and Digi-Reel® packaging. These packaging differences affect supply chain logistics but do not impact electrical or mechanical compatibility.

Q: What compliance certifications apply to all substitute parts?

A: All three devices (CPH5506-TL-E, CPH5520-TL-E, and QSZ2TR) are ROHS3 compliant, REACH unaffected, and carry Moisture Sensitivity Level 1 (Unlimited) rating. These certifications ensure environmental compliance and handling compatibility across all substitute options.

Q: Why is the CPH5506-TL-E classified as obsolete?

A: The CPH5506-TL-E is listed as obsolete by the manufacturer. The CPH5520-TL-E is the active replacement part from onsemi, offering enhanced electrical specifications while maintaining form factor and functional compatibility. New designs should incorporate the CPH5520-TL-E or QSZ2TR to ensure long-term supply availability and production support.
