Key Parameters

Substitute Part Grouping Explanation

Substitution of the MPS2907A-H-AP is determined by strict equivalence in the following electrical and mechanical parameters:

Critical Matching Parameters:

• Transistor Type: PNP (polarity must match)
• Voltage - Collector Emitter Breakdown (Max): 60 V (minimum requirement)
• Mounting Type: Through Hole (mechanical compatibility)
• Package / Case: TO-92-3 (physical form factor)
• Operating Temperature Range: -55°C to 150°C (thermal envelope)

Allowable Variation Parameters:

• Current - Collector (Ic) (Max): Substitute must equal or exceed 600 mA
• Power - Max: Substitute must equal or exceed 625 mW
• Frequency - Transition: Substitute must equal or exceed 200 MHz
• DC Current Gain (hFE): Substitute specifications may differ within design tolerance

The PN2907ATAR from onsemi meets all critical matching parameters and exceeds allowable variation thresholds, qualifying it as a direct substitute for the MPS2907A-H-AP.

Engineering Selection Recommendations

The PN2907ATAR is a qualified substitute for the MPS2907A-H-AP based on the following engineering criteria:

Product Status Advantage: The PN2907ATAR is classified as Active, ensuring continued availability and supply chain support. The MPS2907A-H-AP is Obsolete, making the PN2907ATAR the appropriate long-term solution for new designs and ongoing production.

Compliance Alignment: Both parts maintain RoHS compliance (MPS2907A-H-AP: RoHS Compliant; PN2907ATAR: ROHS3 Compliant), satisfying regulatory requirements. Both parts carry ECCN EAR99 classification and identical HTSUS codes (8541.21.0075).

Electrical Compatibility: The PN2907ATAR meets or exceeds all critical electrical parameters. Maximum collector current (800 mA vs. 600 mA) and collector-emitter breakdown voltage (60 V match) ensure functional compatibility. Transition frequency (200 MHz) and maximum power dissipation (625 mW) are identical.

Design Verification Required: Two parameters differ and require circuit-level verification:

• DC Current Gain (hFE): PN2907ATAR minimum is 100 versus MPS2907A-H-AP minimum of 200. Confirm that circuit biasing and gain requirements accommodate the lower hFE specification.
• Vce Saturation: PN2907ATAR maximum is 1.6V versus MPS2907A-H-AP maximum of 600mV. Verify that switching applications tolerate the higher saturation voltage.

Mechanical Compatibility: Both parts use identical TO-92-3 Through Hole packaging, ensuring direct PCB footprint compatibility without layout modification.

Frequently Asked Questions (FAQ)

Q: Can the PN2907ATAR be used as a direct pin-for-pin replacement for the MPS2907A-H-AP?

A: Yes. Both transistors use the TO-92-3 package with identical pin configuration (Collector, Base, Emitter). Physical and electrical pin assignments are compatible. However, circuit performance must be verified for the two differing electrical parameters (hFE and Vce Saturation) before production implementation.

Q: What is the primary reason the MPS2907A-H-AP is obsolete?

A: The MPS2907A-H-AP is classified as Obsolete by the manufacturer. The PN2907ATAR, manufactured by onsemi, is the active equivalent and recommended substitute for ongoing supply and new designs.

Q: Are there any packaging differences between these parts?

A: No. Both parts are supplied in TO-92-3 Through Hole packages with formed leads. The PN2907ATAR is available in Cut Tape (CT) packaging format, which is standard for active production components.

Q: What is the significance of the lower DC Current Gain (hFE) in the PN2907ATAR?

A: The PN2907ATAR has a minimum hFE of 100 compared to the MPS2907A-H-AP minimum of 200. In amplifier circuits, this requires higher base current to achieve the same collector current. In switching circuits, this may require circuit redesign to ensure adequate base drive. Verify your specific application requirements before substitution.

Q: Why is the Vce Saturation voltage higher in the PN2907ATAR?

A: The PN2907ATAR specifies a maximum Vce Saturation of 1.6V at 50mA base current and 500mA collector current, compared to 600mV for the MPS2907A-H-AP. In switching applications, this results in higher voltage drop across the transistor in the saturated state. Confirm that your circuit design tolerates this additional voltage drop without affecting system performance.

Q: Are both parts RoHS compliant?

A: Yes. The MPS2907A-H-AP is RoHS Compliant, and the PN2907ATAR is ROHS3 Compliant. Both meet current environmental and regulatory standards for electronic components.

Q: What is the inventory status of these parts?

A: The MPS2907A-H-AP has 817 pieces in stock as new original inventory. The PN2907ATAR has 27,888 pieces in stock as new original inventory, providing superior supply chain availability for ongoing production requirements.
