MPS2907A-BP Equivalent & Substitute Parts

Part Overview

The MPS2907A-BP is a PNP bipolar junction transistor manufactured by Micro Commercial Co, designed for small-signal switching and amplification applications. It features a 60 V collector-emitter breakdown voltage, 600 mA maximum collector current, and 625 mW power dissipation in a Through Hole TO-92 package. The device operates across a temperature range of -55°C to 150°C and is RoHS compliant with MSL Level 1 rating.

The MPS2907A-BP is classified as obsolete. Identifying equivalent substitute parts ensures design continuity and maintains supply chain reliability for applications requiring PNP transistor functionality within the specified electrical and mechanical parameters.

Substitute Part Grouping Explanation

Substitution of the MPS2907A-BP is determined by strict equivalence across the following critical parameters:

Mandatory Matching Criteria:

• Transistor polarity: PNP
• Package type: TO-92-3 (Through Hole)
• Voltage rating: Collector-Emitter breakdown voltage ≥ 60 V
• Current rating: Maximum collector current ≥ 600 mA
• Power dissipation: Maximum power ≥ 625 mW
• Operating temperature range: Minimum -55°C to maximum 150°C

The KSA708YBU meets all mandatory substitution criteria. It maintains PNP polarity, identical TO-92-3 package configuration, and exceeds the voltage, current, and power requirements of the MPS2907A-BP. Both devices are RoHS compliant and suitable for Through Hole mounting applications.

Parameter Comparison

Engineering Selection Recommendations

The KSA708YBU is a direct substitute for the MPS2907A-BP based on electrical and mechanical compatibility. The substitute part exceeds the original specifications in collector current (700 mA vs. 600 mA) and power dissipation (800 mW vs. 625 mW), providing design margin for the same voltage class and package footprint.

The KSA708YBU is classified as Active product status, ensuring ongoing availability and supply chain continuity compared to the obsolete MPS2907A-BP. Both devices are housed in identical TO-92-3 Through Hole packages, permitting direct board-level substitution without layout modifications.

The transition frequency of the KSA708YBU (50 MHz) is lower than the MPS2907A-BP (200 MHz). Applications requiring high-frequency switching performance above 50 MHz must evaluate this parameter against circuit requirements.

Frequently Asked Questions (FAQ)

Q: Can the KSA708YBU replace the MPS2907A-BP in existing designs?

A: Yes. The KSA708YBU meets all mandatory electrical parameters (voltage, current, power) and uses the identical TO-92-3 Through Hole package. Direct substitution is possible without PCB modifications.

Q: What is the primary reason for substitution?

A: The MPS2907A-BP is obsolete. The KSA708YBU is an active product with equivalent electrical specifications and identical packaging, ensuring long-term supply availability.

Q: Are there differences in performance between these parts?

A: The KSA708YBU provides higher current capacity (700 mA vs. 600 mA) and power rating (800 mW vs. 625 mW). The transition frequency is lower (50 MHz vs. 200 MHz). Applications operating below 50 MHz encounter no frequency-related limitations.

Q: Do both parts use the same package?
