MPS2907A-L-AP Equivalent & Substitute Parts

Part Overview

The MPS2907A-L-AP is a PNP bipolar junction transistor manufactured by Micro Commercial Co, designed for general-purpose switching and amplification applications. This device features a 60 V collector-emitter breakdown voltage rating and supports collector currents up to 600 mA with a maximum power dissipation of 625 mW. The component is housed in a TO-92 through-hole package with formed leads.

The MPS2907A-L-AP is classified as obsolete, making it necessary to identify functionally equivalent substitute components for new designs and ongoing production requirements. Equivalent parts must maintain compatibility with existing circuit designs while meeting or exceeding the electrical and mechanical specifications of the original device.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MPS2907A-L-AP is determined by strict adherence to the following electrical and mechanical parameters:

Critical Matching Parameters:

• Transistor polarity type (PNP)
• Collector-emitter breakdown voltage rating (60 V minimum)
• Through-hole mounting configuration
• TO-92-3 package form factor with formed leads
• RoHS3 compliance certification

Allowable Parameter Variations: Substitute parts may exceed the following specifications without compromising circuit compatibility:

• Maximum collector current (Ic): 600 mA baseline; higher ratings are acceptable
• Maximum power dissipation: 625 mW baseline; higher ratings are acceptable
• DC current gain (hFE): 100 minimum baseline; higher values are acceptable
• Transition frequency: 200 MHz baseline; lower frequencies are acceptable for non-critical switching applications

The KSA708CYTA meets all critical matching parameters and represents a valid substitute for the MPS2907A-L-AP in applications where the specified electrical characteristics are compatible with circuit requirements.

Parameter Comparison

Engineering Selection Recommendations

MPS2907A-L-AP Status Consideration: The MPS2907A-L-AP is classified as obsolete, indicating discontinued production and limited availability. This status necessitates transition to equivalent alternatives for ongoing production and new design implementations.

KSA708CYTA Suitability: The KSA708CYTA is classified as Last Time Buy, indicating controlled availability with a defined end-of-life date. This part maintains full electrical and mechanical compatibility with the MPS2907A-L-AP across all critical parameters:

• Identical PNP polarity and TO-92-3 package configuration
• Matching 60 V collector-emitter breakdown voltage rating
• Equivalent or superior current handling and power dissipation capabilities
• ROHS3 compliance certification maintained

Compliance and Certification: Both devices maintain ROHS3 compliance, ensuring regulatory compatibility in applications subject to hazardous substance restrictions. The KSA708CYTA carries REACH Unaffected status, providing additional regulatory clarity for European market applications.

Selection Basis: The KSA708CYTA is the appropriate substitute for the MPS2907A-L-AP based on product status alignment, compliance certifications, and electrical parameter compatibility. Circuit designs utilizing the MPS2907A-L-AP may transition to the KSA708CYTA without modification to PCB layouts or circuit topology.

Frequently Asked Questions (FAQ)

Q: Can the KSA708CYTA directly replace the MPS2907A-L-AP in existing circuit designs?

A: Yes. The KSA708CYTA maintains identical package form factor (TO-92-3), polarity (PNP), and critical voltage ratings (60 V). Pin configuration and lead spacing are compatible with existing PCB layouts designed for the MPS2907A-L-AP. No circuit modifications are required.

Q: What are the key differences between these two transistors?

A: The KSA708CYTA provides higher maximum collector current (700 mA versus 600 mA) and greater power dissipation capability (800 mW versus 625 mW). The transition frequency is lower (50 MHz versus 200 MHz). These differences do not prevent substitution in standard switching applications; however, high-frequency circuit designs operating near 200 MHz may require evaluation.

Q: Is the lower transition frequency of the KSA708CYTA a limitation?

A: The 50 MHz transition frequency of the KSA708CYTA is suitable for general-purpose switching and audio-frequency amplification applications. Applications requiring switching speeds above 50 MHz or operating at frequencies approaching 200 MHz require circuit-specific evaluation to confirm compatibility.

Q: Are there temperature range differences between these parts?

A: The MPS2907A-L-AP specifies an operating range of -55°C to 150°C. The KSA708CYTA specifies operation up to 150°C without explicit lower temperature specification. For applications requiring operation below 0°C, the MPS2907A-L-AP specification should be verified against actual circuit requirements.

Q: What is the significance of the "Last Time Buy" status for the KSA708CYTA?

A: Last Time Buy status indicates that onsemi has announced a defined end-of-life date for the KSA708CYTA. Customers requiring this component should verify current availability and plan procurement accordingly. This status does not affect the electrical performance or reliability of existing inventory.

Q: Are both devices RoHS compliant?

A: Yes. Both the MPS2907A-L-AP and KSA708CYTA are ROHS3 compliant, meeting restrictions on hazardous substances in electrical and electronic equipment. The KSA708CYTA additionally carries REACH Unaffected status, confirming compliance with European chemical regulations.

Q: Can the KSA708CYTA be used in high-current applications?

A: The KSA708CYTA supports collector currents up to 700 mA, exceeding the MPS2907A-L-AP baseline of 600 mA. Applications requiring sustained currents in the 600-700 mA range are within the KSA708CYTA specification. Thermal management and power dissipation calculations should account for the 800 mW maximum power rating.
