2SD10300RL Equivalent & Substitute Parts

Part Overview

The 2SD10300RL is an NPN bipolar junction transistor manufactured by Panasonic Electronic Components, designed for surface mount applications in the Mini3-G1 package. This device operates at a maximum collector voltage of 40 V with a collector current rating of 50 mA and a transition frequency of 200 MHz. The part is classified as obsolete, necessitating identification of equivalent substitute components that maintain functional compatibility within target circuit applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2SD10300RL is determined by electrical and mechanical parameter compatibility. The primary substitution criteria are:

Electrical Parameters:

• Transistor type must be NPN
• Collector current rating must equal or exceed 50 mA
• Collector-emitter breakdown voltage must equal or exceed 40 V
• DC current gain (hFE) must support circuit biasing requirements
• Transition frequency must support intended switching or amplification frequency
• Power dissipation capability must accommodate thermal requirements

Mechanical Parameters:

• Surface mount packaging in SOT-23-3 or equivalent footprint
• Pin configuration compatible with TO-236-3 standard
• Moisture sensitivity level of 1 or better

The substitute parts CMPT5088 TR PBFREE and MMBT5088LT1G share identical collector current ratings (50 mA) and compatible package geometries. However, both substitutes operate at a maximum collector-emitter breakdown voltage of 30 V, which is lower than the 2SD10300RL specification of 40 V. These substitutes are suitable only for applications where the circuit design operates below 30 V collector-emitter voltage.

Engineering Selection Recommendations

CMPT5088 TR PBFREE (Central Semiconductor Corp)

This substitute is active in production with RoHS3 compliance and REACH unaffected status. The device is available in high inventory quantities (11,801 pcs). The SOT-23 package provides mechanical compatibility with the original 2SD10300RL footprint. Selection of this part is appropriate for applications where the circuit design operates at collector-emitter voltages not exceeding 30 V. The higher power dissipation rating (350 mW) and saturation voltage specification (500 mV) must be evaluated against circuit requirements.

MMBT5088LT1G (onsemi)

This substitute is active in production with RoHS3 compliance and REACH unaffected status. Inventory availability is substantial (17,400 pcs). The SOT-23-3 (TO-236) package provides direct mechanical compatibility. This part is suitable for applications operating below 30 V collector-emitter voltage. The power dissipation rating (300 mW) and saturation voltage (500 mV) require circuit-level evaluation.

Both substitutes operate at reduced maximum collector-emitter breakdown voltage (30 V versus 40 V) and reduced transition frequency (50 MHz versus 200 MHz). Circuit designs must accommodate these parameter reductions. Both substitutes are currently in active production status, ensuring long-term availability compared to the obsolete 2SD10300RL.

Frequently Asked Questions (FAQ)

Q: Can CMPT5088 TR PBFREE or MMBT5088LT1G be used as direct replacements for 2SD10300RL?

A: Direct replacement is possible only if the circuit design operates at collector-emitter voltages not exceeding 30 V. Both substitutes have a maximum collector-emitter breakdown voltage of 30 V, compared to the 2SD10300RL specification of 40 V. If the original design requires 40 V operation, these substitutes are not compatible.

Q: What are the key electrical differences between the 2SD10300RL and the substitute parts?

A: The primary differences are: (1) Collector-emitter breakdown voltage is 30 V for substitutes versus 40 V for the original; (2) Transition frequency is 50 MHz for substitutes versus 200 MHz for the original; (3) Vce saturation is 500 mV for substitutes versus 200 mV for the original; (4) DC current gain is specified at different test conditions (100 µA, 5 V for substitutes versus 2 mA, 10 V for the original).

Q: Are the package dimensions identical between 2SD10300RL and the substitute parts?

A: All three parts use the SOT-23-3 (TO-236-3, SC-59) surface mount package. The physical footprint and pin configuration are compatible, allowing direct PCB placement without layout modifications.

Q: What is the difference between CMPT5088 TR PBFREE and MMBT5088LT1G?

A: Both parts have identical electrical specifications. The primary differences are manufacturer (Central Semiconductor versus onsemi), packaging format (Tape & Reel designation), power dissipation rating (350 mW versus 300 mW), and operating temperature range (-65°C to 150°C versus -55°C to 150°C). Selection between these parts depends on supply chain availability and thermal requirements.

Q: Why is the transition frequency lower in the substitute parts?

A: The CMPT5088 and MMBT5088 are specified at 50 MHz transition frequency, compared to 200 MHz for the 2SD10300RL. Applications requiring high-frequency switching or amplification above 50 MHz must evaluate whether the reduced transition frequency affects circuit performance.

Q: Are both substitute parts RoHS compliant?

A: Yes, both CMPT5088 TR PBFREE and MMBT5088LT1G are RoHS3 compliant. Both are REACH unaffected. These certifications support use in applications with environmental and regulatory compliance requirements.

Q: What inventory status should be considered when selecting a substitute?

A: Both substitute parts are in active production with substantial inventory availability (CMPT5088: 11,801 pcs; MMBT5088LT1G: 17,400 pcs). The 2SD10300RL is obsolete with limited remaining inventory (998 pcs). Active production status ensures long-term supply continuity for the substitute parts.
