Substitute Part Grouping Explanation

Substitution eligibility for the 2SA1887(F) is determined by the following critical parameters:

Mandatory Matching Criteria:

Transistor polarity: PNP
Collector-emitter breakdown voltage: 50V (maximum rating)
Package type: TO-220-3 through-hole configuration
Operating temperature range: 150°C (maximum junction temperature)

Allowable Parameter Variations:

Collector current rating: Equal to or greater than 10A
Power dissipation: Equal to or greater than 2W
Transition frequency: May vary from specified 45MHz
DC current gain (hFE): May vary from specified 120
Vce saturation: May vary within acceptable operating margins

The substitute parts 2SA1567 and 2SA2222SG satisfy the mandatory matching criteria while meeting or exceeding the allowable parameter variations. Both alternatives maintain PNP polarity, 50V breakdown voltage rating, TO-220-3 package configuration, and 150°C maximum operating temperature.

Engineering Selection Recommendations

2SA1567 (Sanken Electric USA Inc.): This substitute provides active product status with enhanced current handling capability (12A versus 10A) and significantly improved power dissipation rating (35W versus 2W). The device maintains identical voltage and temperature specifications. RoHS compliance certification is provided. This part is suitable for applications requiring higher thermal performance or increased current capacity within the same voltage and package envelope.

2SA2222SG (onsemi): This substitute maintains the 10A collector current specification and provides active product status with enhanced power dissipation (25W versus 2W) and substantially higher transition frequency (230MHz versus 45MHz). ROHS3 compliance and REACH unaffected status are documented. This part is suitable for applications requiring higher frequency operation or improved thermal management while maintaining the original current rating.

Both substitutes are available in active product status, addressing the obsolescence of the original 2SA1887(F). Selection between alternatives depends on application-specific requirements for current capacity, power dissipation, and frequency response within the fixed voltage and package constraints.

Frequently Asked Questions (FAQ)

Q: Can the 2SA1567 directly replace the 2SA1887(F) in existing designs?

A: The 2SA1567 maintains identical voltage rating (50V), package type (TO-220-3), and operating temperature (150°C). The higher collector current rating (12A versus 10A) and power dissipation (35W versus 2W) provide enhanced capability. Direct substitution is permissible where the application does not require the specific electrical characteristics of the original part.

Q: What is the primary difference between the 2SA2222SG and 2SA1567 substitutes?

A: The 2SA2222SG provides significantly higher transition frequency (230MHz versus 40MHz) and maintains the original 10A collector current specification. The 2SA1567 offers higher power dissipation capability (35W versus 25W) and increased collector current (12A). Selection depends on whether the application prioritizes frequency response or thermal performance.

Q: Are both substitute parts available in the same package configuration?

A: Both 2SA1567 and 2SA2222SG utilize the TO-220-3 through-hole package, maintaining mechanical and thermal interface compatibility with the original 2SA1887(F). Supplier device packages differ (TO-220F and TO-220ML respectively), but both conform to the standard TO-220-3 case outline.

Q: What compliance certifications apply to the substitute parts?

A: The 2SA1567 carries RoHS compliance certification. The 2SA2222SG carries ROHS3 compliance certification and REACH unaffected status. Both parts maintain EAR99 export classification and identical HTSUS commodity codes as the original part.

Q: Can the 2SA2222SG be used in low-frequency applications originally designed for the 2SA1887(F)?

A: The 2SA2222SG operates at 230MHz transition frequency, substantially higher than the original 45MHz specification. In low-frequency applications, this enhanced frequency capability does not create incompatibility. The part maintains all voltage, current, and temperature specifications required for direct substitution.

Q: What is the moisture sensitivity level for the substitute parts?

A: The 2SA1567 maintains MSL 1 (Unlimited) classification, identical to the original part. The 2SA2222SG carries MSL Not Applicable designation, indicating no moisture sensitivity constraints during storage or handling.
