DSA5002R0L Equivalent & Substitute Parts

Part Overview

The DSA5002R0L is a PNP bipolar junction transistor manufactured by Panasonic Electronic Components, rated for 50 V collector-emitter breakdown voltage and 500 mA maximum collector current. This surface mount device in SC-85 package (SMini3-F2-B supplier package) is designed for general-purpose switching and amplification applications operating at frequencies up to 130 MHz with a maximum power dissipation of 150 mW.

The DSA5002R0L has been discontinued at DiGi Electronics. Equivalent and substitute parts are available from active manufacturers including Rohm Semiconductor and onsemi, providing continued design support and component availability for applications requiring PNP transistor functionality within specified electrical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DSA5002R0L is determined by the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Transistor type must be PNP
• Collector current rating must be equal to or greater than 500 mA
• Collector-emitter breakdown voltage must be equal to or greater than 50 V
• Operating temperature range must support 150°C (TJ)
• Surface mount mounting type required

Mechanical Compatibility Criteria:

• Package form factor must be compatible with SC-85 or equivalent surface mount footprint
• Moisture sensitivity level must be 1 (Unlimited) or equivalent

Substitute parts are grouped into two categories based on voltage rating alignment:

Category A - Voltage-Matched Substitutes (50 V Rating): Parts maintaining the original 50 V collector-emitter breakdown voltage specification, providing direct electrical equivalence for applications with higher voltage requirements.

Category B - Voltage-Reduced Substitutes (30 V Rating): Parts with 30 V collector-emitter breakdown voltage, suitable for applications where the circuit operates at voltages not exceeding 30 V. These parts offer enhanced performance characteristics in frequency response and power dissipation within their voltage envelope.

Engineering Selection Recommendations

For Direct Voltage-Matched Replacement (50 V Applications):

The 50A02MH-TL-E from onsemi is the primary substitute for applications requiring the full 50 V collector-emitter breakdown voltage specification. This part maintains voltage equivalence with the original DSA5002R0L while offering superior performance characteristics: 600 mW maximum power dissipation (versus 150 mW), 690 MHz transition frequency (versus 130 MHz), and improved saturation voltage characteristics. The 50A02MH-TL-E is currently in active production status with ROHS3 compliance and REACH unaffected status, ensuring long-term availability and regulatory compliance.

For Voltage-Reduced Applications (≤30 V Operation):

The Rohm Semiconductor 2SAR502 series (2SAR502U3HZGT106, 2SAR502U3T106, and 2SAR502UBTL) provides active alternatives for circuits operating at 30 V or below. All three variants are currently in active production with ROHS3 compliance and REACH unaffected status. These parts deliver enhanced performance within their voltage envelope: 200 mW power dissipation and 520 MHz transition frequency. The 2SAR502UBTL variant is recommended for direct package compatibility, as it maintains the SC-85 package form factor identical to the original DSA5002R0L. The 2SAR502U3HZGT106 and 2SAR502U3T106 variants use SC-70/SOT-323 packages and require PCB layout modification.

All substitute parts maintain PNP transistor type, 500 mA collector current rating, 150°C operating temperature capability, and MSL 1 moisture sensitivity level, ensuring functional compatibility within their respective voltage ratings.

Frequently Asked Questions (FAQ)

Q: Can the 2SAR502 series parts replace the DSA5002R0L in all applications?

A: The 2SAR502 series parts are suitable substitutes only for applications where the circuit operates at voltages not exceeding 30 V. The original DSA5002R0L is rated for 50 V collector-emitter breakdown voltage. If your application requires the full 50 V rating, use the 50A02MH-TL-E from onsemi instead.

Q: What is the difference between 2SAR502U3HZGT106, 2SAR502U3T106, and 2SAR502UBTL?

A: All three are PNP transistors from Rohm Semiconductor with identical electrical specifications (30 V, 500 mA, 520 MHz). The primary difference is package form factor: 2SAR502U3HZGT106 and 2SAR502U3T106 use SC-70/SOT-323 packages, while 2SAR502UBTL uses SC-85 package. The SC-85 package (2SAR502UBTL) provides direct footprint compatibility with the original DSA5002R0L.

Q: Does the 50A02MH-TL-E require PCB layout changes?

A: The 50A02MH-TL-E uses a 3-MCPH package (3-SMD, Flat Lead), which differs from the original SC-85 package. PCB layout modification is required to accommodate the different package footprint and pin configuration.

Q: Are all substitute parts RoHS compliant?

A: Yes. The original DSA5002R0L is RoHS Compliant. All substitute parts (2SAR502U3HZGT106, 2SAR502U3T106, 2SAR502UBTL, and 50A02MH-TL-E) are ROHS3 Compliant, meeting current regulatory requirements.

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

A: All parts, including the original DSA5002R0L and all substitutes, have MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage and handling.

Q: Which substitute offers the best performance improvement?

A: The 50A02MH-TL-E provides the most significant performance enhancement: 600 mW maximum power dissipation (4× the original 150 mW), 690 MHz transition frequency (5.3× the original 130 MHz), and superior saturation voltage characteristics (120 mV at 10 mA, 100 mA versus 600 mV at 30 mA, 300 mA). This part maintains the original 50 V voltage rating while delivering substantially improved electrical performance.

Q: Can I use the 2SAR502UBTL as a direct drop-in replacement?

A: The 2SAR502UBTL provides package footprint compatibility (SC-85) with the original DSA5002R0L. However, it is electrically suitable only for applications operating at 30 V or below. Verify your circuit voltage requirements before substitution.
