MPS2369RLRAG Equivalent & Substitute Parts

Part Overview

The MPS2369RLRAG is an NPN bipolar junction transistor (BJT) manufactured by onsemi, designed for general-purpose switching and amplification applications. This device features a maximum collector current of 200 mA, collector-emitter breakdown voltage of 15 V, and maximum power dissipation of 625 mW in a through-hole TO-92 package.

The MPS2369RLRAG is classified as obsolete. Locating equivalent or substitute components is necessary to support ongoing maintenance, repair, and production requirements for legacy systems utilizing this transistor. Substitute parts must maintain electrical compatibility across critical parameters including maximum collector current, breakdown voltage, saturation characteristics, and operating temperature range.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MPS2369RLRAG is determined by strict electrical and mechanical compatibility across the following parameters:

Electrical Compatibility Criteria:

• Transistor type must be NPN
• Maximum collector current (Ic) must be equal to or greater than 200 mA
• Collector-emitter breakdown voltage (Vce(BR)CEO) must be equal to or greater than 15 V
• Operating temperature range must encompass -55°C to 150°C
• Saturation voltage and cutoff current characteristics must be within acceptable limits for the application

Mechanical Compatibility Criteria:

• Package type may differ (through-hole or surface-mount variants are acceptable if electrical parameters are met)
• Moisture sensitivity level must be rated at MSL 1 or equivalent

The MMBT2369ALT1G meets all electrical compatibility requirements while offering a surface-mount alternative in SOT-23-3 packaging. This substitute maintains identical maximum collector current, breakdown voltage, and operating temperature range. The primary difference is the mounting technology and reduced maximum power dissipation due to the smaller package footprint.

Engineering Selection Recommendations

For Through-Hole Applications: The MPS2369RLRAG remains the specified component for legacy through-hole circuit designs. However, due to obsolete status, availability is limited to existing inventory. The 680 pieces currently in stock represent a finite supply.

For New Designs or Redesigns: The MMBT2369ALT1G is the recommended substitute for applications where surface-mount technology is acceptable. This part is manufactured by the same supplier (onsemi), maintains active product status, and offers superior availability (125,200 pieces in stock). The MMBT2369ALT1G is RoHS3 compliant, providing enhanced environmental and regulatory compliance compared to the obsolete through-hole variant.

Power Dissipation Consideration: The MMBT2369ALT1G has a maximum power dissipation of 225 mW compared to 625 mW for the MPS2369RLRAG. Applications requiring sustained power dissipation above 225 mW must retain the through-hole MPS2369RLRAG or implement thermal management modifications for the surface-mount substitute.

Compliance and Certifications: Both parts carry identical REACH and ECCN classifications (REACH Unaffected, EAR99). The MMBT2369ALT1G provides additional RoHS3 compliance certification, making it suitable for regulated markets and modern supply chain requirements.

Frequently Asked Questions (FAQ)

Q: Can the MMBT2369ALT1G directly replace the MPS2369RLRAG in existing through-hole PCB designs?

A: No. The MMBT2369ALT1G uses SOT-23-3 surface-mount packaging, while the MPS2369RLRAG uses TO-92-3 through-hole packaging. PCB layout and footprint modifications are required. However, the electrical characteristics are compatible for functional substitution in redesigned boards.

Q: What are the key electrical differences between these two parts?

A: The transistor type, maximum collector current (200 mA), collector-emitter breakdown voltage (15 V), and operating temperature range (-55°C to 150°C) are identical. The primary differences are maximum power dissipation (625 mW vs. 225 mW) and DC current gain specifications at different test conditions (40 @ 10 mA, 1 V vs. 20 @ 100 mA, 1 V).

Q: Is the MMBT2369ALT1G suitable for high-power applications?

A: The MMBT2369ALT1G is rated for maximum power dissipation of 225 mW. Applications requiring sustained power dissipation above this threshold must use the MPS2369RLRAG or implement external thermal management. Verify application power requirements before substitution.

Q: What is the availability status of each part?

A: The MPS2369RLRAG is obsolete with 680 pieces in current stock. The MMBT2369ALT1G is active with 125,200 pieces in stock, providing significantly greater long-term availability and supply chain reliability.

Q: Are there any compliance or regulatory differences?

A: Both parts are REACH Unaffected and classified as EAR99. The MMBT2369ALT1G carries additional RoHS3 compliance certification, making it preferable for applications subject to environmental or regulatory requirements.

Q: Can I use the MMBT2369ALT1G in a through-hole socket designed for the MPS2369RLRAG?

A: No. The MMBT2369ALT1G requires surface-mount assembly on a PCB. It cannot be inserted into through-hole sockets or breadboards designed for TO-92 packages.
