Engineering Selection Recommendations

BZT52-C30S_R1_00001 (Panjit International Inc.)

This part provides direct electrical and mechanical compatibility with the DZ2J30000L. Both components share identical 30 V nominal voltage, 200 mW power rating, ±5% tolerance, and SC-90/SOD-323F packaging. The BZT52-C30S_R1_00001 is in active product status with ROHS3 compliance and unlimited moisture sensitivity rating. The lower impedance specification (80 Ω versus 160 Ω) represents improved dynamic performance characteristics. This part is suitable for direct substitution in applications requiring equivalent electrical performance.

UDZSTE-1730B (Rohm Semiconductor)

This part matches the DZ2J30000L in voltage, power rating, and package specifications. The UDZSTE-1730B offers superior tolerance specification (±3% versus ±5%), providing tighter voltage regulation. Operating temperature range is specified as -55°C to 150°C. This part is in active status with ROHS3 compliance. The higher impedance specification (200 Ω) may affect transient response characteristics in applications sensitive to dynamic impedance. This part is suitable for applications requiring improved voltage accuracy.

UDZVTE-1730B (Rohm Semiconductor)

This part provides electrical and mechanical equivalence to the DZ2J30000L with 30 V nominal voltage, 200 mW power rating, and SC-90/SOD-323F packaging. The UDZVTE-1730B is in active product status with the highest inventory availability (95,300 pieces). Operating temperature range is -55°C to 150°C. ROHS3 compliance and unlimited moisture sensitivity rating are confirmed. Tolerance specification is not provided in the data. This part is suitable for high-volume procurement scenarios.
