Key Parameters

Substitute Part Grouping Explanation

Substitution of the DSA900100L is determined by strict equivalence across the following critical electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Transistor polarity: PNP type
• Maximum collector current: 100mA
• Maximum collector-emitter breakdown voltage: 50V
• Maximum power dissipation: 125mW or greater
• Operating temperature range: 150°C or higher

Mechanical Equivalence Criteria:

• Mounting type: Surface Mount
• Package classification: SC-89 / SOT-490 family
• Moisture sensitivity: MSL 1 (Unlimited)

Compliance Criteria:

• RoHS compliance status
• ECCN classification: EAR99

The 2SAR523EBTL manufactured by Rohm Semiconductor meets all substitution criteria. This part maintains identical electrical ratings for collector current and breakdown voltage, exceeds power dissipation requirements, and operates within the specified temperature range. The device is classified within the same package family and maintains equivalent moisture sensitivity characteristics.

Engineering Selection Recommendations

DSA900100L (Panasonic): This part is discontinued at DiGi Electronics. Existing inventory of 59,200 pieces is available through current stock channels. Selection of this part is limited to applications where existing supply is accessible and component obsolescence risk is acceptable.

2SAR523EBTL (Rohm Semiconductor): This part carries Active product status with 42,100 pieces in current inventory. The device is ROHS3 compliant and REACH unaffected, providing enhanced regulatory compliance documentation. The substitute part exceeds the original specification in power dissipation (150mW versus 125mW) and transition frequency (300MHz versus 150MHz), making it suitable for direct substitution in all applications where the DSA900100L is specified. The active product status ensures long-term availability and supply chain continuity.

For new designs and production requiring component continuity, the 2SAR523EBTL is the appropriate selection. For legacy system maintenance where the original part number is specified, the DSA900100L remains available through existing inventory channels while supplies persist.

Frequently Asked Questions (FAQ)

Q: Can the 2SAR523EBTL directly replace the DSA900100L in existing circuit designs?

A: Yes. Both devices are PNP transistors with identical maximum collector current (100mA) and collector-emitter breakdown voltage (50V) ratings. Both operate at 150°C maximum junction temperature and are classified within the SC-89/SOT-490 package family. The 2SAR523EBTL exceeds the original power dissipation and frequency specifications, making it functionally compatible for all applications where the DSA900100L is specified.

Q: Are there package compatibility concerns between these parts?

A: Both the DSA900100L and 2SAR523EBTL are surface mount devices classified within the SC-89 and SOT-490 package standards. The DSA900100L uses the SSMini3-F3-B supplier package format, while the 2SAR523EBTL uses the EMT3F (SOT-416FL) format. Both packages are mechanically and electrically compatible within the SC-89/SOT-490 classification, supporting direct PCB footprint compatibility.

Q: What is the difference in DC current gain between these parts?

A: The DSA900100L specifies a minimum DC current gain (hFE) of 210 at 2mA collector current and 10V collector-emitter voltage. The 2SAR523EBTL specifies a minimum DC current gain of 120 at 1mA collector current and 6V collector-emitter voltage. These measurements are taken at different operating points and do not prevent functional substitution in circuit applications.

Q: What are the saturation voltage differences?

A: The DSA900100L specifies a maximum saturation voltage of 500mV at 10mA base current and 100mA collector current. The 2SAR523EBTL specifies a maximum saturation voltage of 400mV at 5mA base current and 50mA collector current. The 2SAR523EBTL demonstrates lower saturation voltage at its specified test conditions, which is advantageous for switching applications.

Q: Are both parts RoHS compliant?

A: Yes. The DSA900100L is RoHS Compliant. The 2SAR523EBTL is ROHS3 Compliant, representing an enhanced compliance standard. Both parts meet RoHS requirements for hazardous substance restrictions.

Q: What is the moisture sensitivity rating for these parts?

A: Both the DSA900100L and 2SAR523EBTL carry Moisture Sensitivity Level (MSL) 1 (Unlimited), indicating no moisture sensitivity restrictions during storage, handling, or assembly processes.

Q: Is the 2SAR523EBTL available in the same packaging options as the DSA900100L?

A: The DSA900100L is supplied in SSMini3-F3-B package format. The 2SAR523EBTL is supplied in EMT3F (SOT-416FL) package format. Both packages conform to the SC-89 and SOT-490 standards and are mechanically compatible for surface mount assembly on standard PCB footprints designed for these package classifications.
