Key Parameters

Substitute Part Grouping Explanation

Substitution of the BY133-AP is determined by electrical and mechanical parameter equivalence within the rectifier diode category. The substitute part BY133GP-AP shares identical electrical specifications across all critical parameters: 1300 V reverse voltage rating, 1 A average rectified current, 1.1 V forward voltage drop at 1 A, 5 µA reverse leakage current at rated voltage, standard recovery speed characteristics, and identical junction temperature operating range. Both parts utilize the same DO-41 through-hole axial package configuration and are manufactured by Micro Commercial Co under the same base product number (BY133).

The primary distinction between these parts is product status and packaging format. The BY133-AP is classified as obsolete, while the BY133GP-AP maintains active product status. The BY133GP-AP is supplied in Tape & Box (TB) packaging, whereas the BY133-AP packaging format is not specified in the provided data. Both parts are ROHS3 compliant and carry identical export classification (EAR99) and tariff codes (HTSUS 8541.10.0080).

Parameter Comparison

Engineering Selection Recommendations

The BY133GP-AP is a direct electrical and mechanical equivalent to the BY133-AP. All electrical parameters, thermal characteristics, and physical package specifications are identical. The BY133GP-AP is the appropriate selection for new designs and procurement activities due to its active product status, ensuring long-term availability and manufacturer support.

For existing applications currently using the BY133-AP, transition to the BY133GP-AP is supported by complete parameter equivalence. No circuit redesign or validation is required from an electrical performance standpoint. The BY133GP-AP maintains ROHS3 compliance and carries the same export and tariff classifications as the original part.

The BY133GP-AP is supplied in Tape & Box (TB) packaging format, which is standard for high-volume production environments. Inventory availability for the BY133GP-AP is 742 pieces as new original stock.
