MPS2369G Equivalent & Substitute Parts

Part Overview

The MPS2369G is an NPN bipolar junction transistor (BJT) manufactured by onsemi, rated for 15 V collector-emitter breakdown voltage and 200 mA maximum collector current in a through-hole TO-92 package. This device is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. The MPS2369G remains available in inventory, but designers and procurement teams require active alternatives to ensure long-term component availability and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MPS2369G is determined by electrical parameter equivalence across the following criteria:

Electrical Equivalence Requirements:

• Transistor type: NPN
• Maximum collector current (Ic): 200 mA
• Maximum collector-emitter breakdown voltage (Vce(br)ceo): 15 V
• Operating temperature range: −55°C to 150°C (TJ)

Mechanical Compatibility Considerations:

• The MPS2369G uses through-hole TO-92 packaging
• Substitute parts may use alternative packaging (surface mount) provided electrical parameters remain equivalent
• Package differences require circuit board redesign and assembly process modification

The MMBT2369ALT1G meets all electrical equivalence requirements and is manufactured by the same supplier (onsemi), ensuring consistent device characteristics and performance within the specified operating envelope.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The MPS2369G is classified as obsolete. The MMBT2369ALT1G is an active product from the same manufacturer, providing assured long-term availability and supply chain stability for new designs and production continuity.

Compliance and Certification: Both devices carry identical regulatory compliance status: REACH Unaffected and Moisture Sensitivity Level 1 (Unlimited). The MMBT2369ALT1G additionally carries RoHS3 Compliance certification, meeting current environmental and hazardous substance restrictions.

Electrical Equivalence: The MMBT2369ALT1G maintains electrical equivalence across all critical parameters: NPN type, 200 mA maximum collector current, 15 V breakdown voltage, and −55°C to 150°C operating temperature range. The reduced maximum power rating (225 mW versus 625 mW) reflects the smaller physical footprint of the SOT-23-3 package and does not affect functional equivalence in typical low-power switching applications.

Packaging and Integration: Selection between through-hole (TO-92) and surface-mount (SOT-23) packaging depends on circuit board design and assembly capabilities. Through-hole mounting is suitable for manual assembly and prototyping; surface-mount packaging is standard for automated production environments.

Frequently Asked Questions (FAQ)

Q: Can the MMBT2369ALT1G directly replace the MPS2369G in existing circuit boards?

A: Electrical substitution is valid; however, mechanical substitution requires circuit board redesign. The MPS2369G uses through-hole TO-92 packaging, while the MMBT2369ALT1G uses surface-mount SOT-23-3 packaging. Pin-to-pin electrical function is equivalent, but physical mounting and board layout differ.

Q: What is the significance of the different power ratings (625 mW versus 225 mW)?

A: Power rating reflects the thermal dissipation capability of each package. The TO-92 through-hole package dissipates 625 mW; the SOT-23-3 surface-mount package dissipates 225 mW. For applications operating below 225 mW, both devices are equivalent. Applications requiring power dissipation between 225 mW and 625 mW require thermal analysis to confirm SOT-23-3 suitability.

Q: Are there differences in DC current gain (hFE) between these devices?

A: Yes. The MPS2369G specifies hFE (Min) of 40 @ 10 mA, 1 V. The MMBT2369ALT1G specifies hFE (Min) of 20 @ 100 mA, 1 V. These measurements occur at different operating points. For applications sensitive to current gain at specific collector currents, circuit performance must be evaluated against the actual operating conditions.

Q: Why is the MPS2369G classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The MMBT2369ALT1G is the active equivalent, ensuring continued availability for new designs and production orders.

Q: What compliance certifications apply to both devices?

A: Both devices are REACH Unaffected and carry Moisture Sensitivity Level 1 (Unlimited). The MMBT2369ALT1G additionally carries RoHS3 Compliance certification, meeting current environmental regulations for hazardous substance restrictions.

Q: Can the MMBT2369ALT1G be used in high-temperature applications?

A: Both devices operate across the same temperature range: −55°C to 150°C (TJ). Temperature capability is equivalent between the two devices.
