Substitute Part Grouping Explanation

Substitution is strictly based on identical or matching electrical and mechanical parameters, specifically: BJT type (PNP), collector-emitter breakdown voltage (45 V), maximum collector current (200 mA), Vce saturation (250mV @ 1mA, 10mA), DC current gain (hFE min 60 @ 10µA, 1V), maximum power dissipation (350 mW), mounting type (surface mount), and package/case (die). Compliance parameters including RoHS and MSL are also matched. Only substitute parts with values precisely matching these parameters are included.

Engineering Selection Recommendations

The CP588-BCY70-WN is obsolete, while the substitute part CP788X-BCY70-WN is active. Both parts are ROHS3 compliant and have moisture sensitivity level (MSL) 1 (unlimited), supporting direct compatibility in compliant systems. They share all listed electrical and mechanical characteristics. Selection based on lifecycle status favors CP788X-BCY70-WN due to its active status.

Frequently Asked Questions (FAQ)

Q1: What criteria are used to qualify an equivalent BJT substitute for CP588-BCY70-WN?
A1: Only electrical and mechanical parameters explicitly provided (type, voltage, current, saturation voltage, current gain, power, mounting type, package/case), and compliance characteristics (RoHS, MSL) are used for substitution.

Q2: Is CP788X-BCY70-WN cross-compatible with CP588-BCY70-WN in existing designs?
A2: CP788X-BCY70-WN matches all provided parameters and compliance attributes, supporting direct replacement in layouts and applications using surface mount die form factor.

Q3: Do compliance certifications differ between the main and substitute part numbers?
A3: Both CP588-BCY70-WN and CP788X-BCY70-WN are ROHS3 compliant and have MSL 1 (unlimited).

Q4: Are differences in inventory or product status relevant for substitution?
A4: Product status identifies the lifecycle stage; CP588-BCY70-WN is obsolete, while CP788X-BCY70-WN is active, supporting longer-term availability.

Q5: Are there any package or mounting variations to consider when selecting a substitute?
A5: Both part numbers are supplied as die format for surface mount applications, maintaining package and mounting compatibility.
