DSC5002S0L Equivalent & Substitute Parts

Part Overview

The DSC5002S0L is a Panasonic Electronic Components NPN bipolar junction transistor (BJT) designed for general-purpose switching and amplification applications. This surface mount device operates at 50V collector-emitter breakdown voltage with a maximum collector current of 500mA and 150mW power dissipation. The part is currently discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives for ongoing design support and production requirements.

Substitute Part Grouping Explanation

Substitution of the DSC5002S0L is determined by strict equivalence across the following critical parameters:

Mandatory Matching Criteria:

Transistor Type: NPN configuration
Current Rating: 500mA maximum collector current
Mounting Type: Surface Mount
Environmental Compliance: RoHS compliance status

Voltage Consideration: The DSC5002S0L operates at 50V maximum collector-emitter breakdown voltage. Substitute parts must maintain voltage ratings sufficient for the application circuit. The identified substitute, 2SCR502U3T106, operates at 30V maximum breakdown voltage, which represents a reduced voltage capability and is suitable only for applications where circuit voltage does not exceed 30V.

Performance Parameters: Frequency response, power dissipation, and saturation characteristics vary between the main part and substitutes. These variations must be evaluated against specific application requirements.

Engineering Selection Recommendations

DSC5002S0L Status: The DSC5002S0L is discontinued at DiGi Electronics. Current inventory of 4200 pieces is available through existing stock channels. This part maintains RoHS compliance and MSL Level 1 rating, indicating no moisture sensitivity constraints during storage and handling.

2SCR502U3T106 Availability: The 2SCR502U3T106 from Rohm Semiconductor is an active product with 811 pieces in current inventory. This part carries ROHS3 compliance and REACH Unaffected status, meeting current environmental and regulatory requirements.

Selection Basis: Both parts share identical collector current ratings (500mA) and operating temperature limits (150°C). The primary differentiation is voltage rating: the DSC5002S0L supports 50V operation, while the 2SCR502U3T106 is rated for 30V maximum. Selection between these parts depends on circuit voltage requirements. Applications operating below 30V can utilize the 2SCR502U3T106. Applications requiring 30V to 50V operation require the DSC5002S0L or alternative parts rated for higher voltages.

Package differences exist: DSC5002S0L uses SC-85 (SMini3-F2-B), while 2SCR502U3T106 uses SC-70/SOT-323 (UMT3). PCB layout and footprint modifications are necessary when transitioning between these packages.

Frequently Asked Questions (FAQ)

Q: Can the 2SCR502U3T106 directly replace the DSC5002S0L in all applications?

A: No. The 2SCR502U3T106 has a maximum collector-emitter breakdown voltage of 30V, compared to 50V for the DSC5002S0L. Direct substitution is valid only for circuits operating at 30V or below. Applications requiring voltages between 30V and 50V cannot use this substitute without circuit redesign.

Q: What are the package differences between these parts?

A: The DSC5002S0L uses SC-85 package (SMini3-F2-B), while the 2SCR502U3T106 uses SC-70/SOT-323 package (UMT3). These are different physical packages requiring different PCB footprints. Mechanical compatibility cannot be assumed; PCB layout verification is necessary.

Q: Are both parts RoHS compliant?

A: Yes. The DSC5002S0L is RoHS Compliant, and the 2SCR502U3T106 is ROHS3 Compliant. Both meet current environmental regulations. The 2SCR502U3T106 additionally carries REACH Unaffected status.

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

A: Both the DSC5002S0L and 2SCR502U3T106 are rated MSL Level 1 (Unlimited), indicating no moisture sensitivity constraints. Standard handling and storage practices apply.

Q: How do the frequency characteristics compare?

A: The DSC5002S0L has a transition frequency of 160MHz, while the 2SCR502U3T106 operates at 360MHz. The higher frequency capability of the 2SCR502U3T106 may provide improved performance in high-frequency switching applications but is not required for lower-frequency designs.

Q: What are the saturation voltage differences?

A: The DSC5002S0L exhibits 600mV saturation voltage at 30mA base current and 300mA collector current. The 2SCR502U3T106 shows 300mV saturation at 10mA base current and 200mA collector current. Lower saturation voltage in the 2SCR502U3T106 may reduce power dissipation in saturated switching applications.

Q: Are there inventory considerations for part selection?

A: The DSC5002S0L is discontinued but has 4200 pieces available in existing stock. The 2SCR502U3T106 is an active product with 811 pieces in inventory. Long-term availability favors the 2SCR502U3T106 for new designs, while the DSC5002S0L remains available for legacy system support through existing stock channels.
