BY133-TP Equivalent & Substitute Parts

Part Overview

The BY133-TP is a general-purpose rectifier diode manufactured by Micro Commercial Co, rated for 1300 V DC reverse voltage and 1 A average rectified current in a DO-41 through-hole axial package. This component is classified as obsolete, which necessitates identification of active equivalent parts for continued system support and procurement.

The BY133-TP operates across a junction temperature range of -55°C to 150°C and exhibits standard recovery characteristics with forward voltage of 1.1 V maximum at 1 A. The part is RoHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BY133-TP is determined by electrical and mechanical parameter equivalence across the following criteria:

Electrical Parameters:

• Voltage - DC Reverse (Vr) (Max): 1300 V
• Current - Average Rectified (Io): 1 A
• Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 1 A
• Current - Reverse Leakage @ Vr: 5 µA @ 1300 V
• Speed: Standard Recovery >500ns, > 200mA (Io)
• Capacitance @ Vr, F: 15 pF @ 4V, 1MHz
• Operating Temperature - Junction: -55°C to 150°C

Mechanical Parameters:

• Package / Case: DO-204AL, DO-41, Axial
• Mounting Type: Through Hole

Compliance Parameters:

• RoHS Status: ROHS3 Compliant

The BY133GP-TP meets all electrical and mechanical requirements for direct substitution. The primary distinction is product status (active versus obsolete) and packaging format (Tape & Reel versus bulk).

Parameter Comparison

Engineering Selection Recommendations

The BY133GP-TP is a direct electrical and mechanical equivalent to the BY133-TP. Both parts share identical electrical specifications, operating temperature range, package designation, and RoHS3 compliance status.

The BY133GP-TP is classified as active product status, ensuring continued availability and manufacturer support. The BY133-TP is obsolete and subject to discontinuation.

The primary difference between the two parts is packaging format: the BY133-TP is supplied in bulk configuration, while the BY133GP-TP is supplied in Tape & Reel (TR) format. This distinction affects procurement logistics and automated assembly compatibility but does not alter electrical or mechanical performance.

For new designs and system replacements, the BY133GP-TP is the appropriate selection due to active product status and compliance certifications. Existing systems using the BY133-TP may be directly retrofitted with the BY133GP-TP without circuit modification or performance degradation.
