MPS6560G Equivalent & Substitute Parts

Part Overview

The MPS6560G is an NPN bipolar junction transistor manufactured by onsemi, designed for general-purpose switching and amplification applications. This device features a maximum collector current of 500 mA, collector-emitter breakdown voltage of 25 V, and a power dissipation rating of 625 mW in a through-hole TO-92 package. The MPS6560G is classified as obsolete, making identification of functionally equivalent substitute components necessary for ongoing design support, maintenance, and production continuity.

Substitute Part Grouping Explanation

Substitution of the MPS6560G is determined by electrical and mechanical compatibility within the NPN bipolar transistor category. The primary substitution candidate is the MMBT489LT1G, which maintains NPN polarity and operates within the same temperature range (-55°C to 150°C).

Substitution eligibility is based on the following criteria:

• Transistor Polarity: NPN configuration required
• Collector Current Rating: Substitute must equal or exceed 500 mA maximum
• Collector-Emitter Breakdown Voltage: Substitute must equal or exceed 25 V
• Power Dissipation: Substitute must equal or exceed 625 mW
• Operating Temperature Range: Substitute must support -55°C to 150°C
• Saturation Characteristics: Substitute Vce(sat) must be compatible with circuit requirements

The MMBT489LT1G exceeds all electrical parameters of the MPS6560G while offering enhanced performance specifications. The primary difference is packaging: the MPS6560G uses through-hole TO-92 mounting, while the MMBT489LT1G uses surface-mount SOT-23-3 packaging. This substitution requires circuit board redesign and assembly process modification.

Parameter Comparison

Engineering Selection Recommendations

The MPS6560G is classified as obsolete. The MMBT489LT1G is the identified substitute and carries active product status with RoHS3 compliance certification. Selection of the MMBT489LT1G is appropriate for new designs and production continuity where surface-mount technology is feasible.

The MMBT489LT1G provides superior electrical performance across all measured parameters: collector current capacity is doubled (1 A versus 500 mA), breakdown voltage is increased (30 V versus 25 V), saturation voltage is reduced (200 mV versus 500 mV), and transition frequency is elevated (100 MHz versus 60 MHz). Power dissipation capability is marginally increased (710 mW versus 625 mW).

Both devices maintain identical operating temperature ranges and moisture sensitivity classifications. The MMBT489LT1G meets REACH compliance requirements, whereas the MPS6560G is REACH unaffected due to its obsolete status.

Substitution requires verification that circuit board layout and assembly processes support SOT-23-3 surface-mount packaging. Pin configuration and functional connectivity must be validated against specific application schematics.

Frequently Asked Questions (FAQ)

Q: Can the MMBT489LT1G directly replace the MPS6560G in existing through-hole circuit boards?

A: No. The MMBT489LT1G uses SOT-23-3 surface-mount packaging, while the MPS6560G uses TO-92-3 through-hole packaging. Direct board-level substitution is not possible without circuit board redesign and assembly process modification. Adapter solutions or board rework may be required for prototype or low-volume applications.

Q: Are the electrical characteristics of the MMBT489LT1G compatible with circuits designed for the MPS6560G?

A: Yes. The MMBT489LT1G exceeds all maximum electrical ratings of the MPS6560G. Collector current capacity, breakdown voltage, power dissipation, and frequency response are all superior. Circuits designed within the MPS6560G specifications will operate within the MMBT489LT1G envelope. However, saturation voltage is significantly lower (200 mV versus 500 mV), which may affect switching speed and power dissipation in saturation-mode applications.

Q: What is the significance of the reduced Vce saturation voltage in the MMBT489LT1G?

A: Lower saturation voltage indicates improved switching efficiency and reduced power dissipation during saturation. In switching applications, this results in lower heat generation and faster switching transitions. In linear amplification applications, this may alter biasing characteristics and require circuit adjustment.

Q: Are moisture sensitivity levels identical between these devices?

A: Yes. Both the MPS6560G and MMBT489LT1G carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity restrictions for storage, handling, or assembly.

Q: Does the MMBT489LT1G meet current environmental compliance standards?

A: Yes. The MMBT489LT1G is RoHS3 compliant and REACH unaffected. The MPS6560G, being obsolete, carries REACH unaffected status. Both devices meet current environmental regulatory requirements for their respective product statuses.

Q: What is the impact of increased transition frequency on circuit performance?

A: The MMBT489LT1G transition frequency of 100 MHz versus the MPS6560G at 60 MHz indicates faster switching capability and higher-frequency operation potential. This allows the substitute to function in higher-frequency applications without performance degradation. Existing circuits will experience no negative impact from this enhanced specification.

Q: Are there pin-to-pin compatibility considerations between TO-92-3 and SOT-23-3 packages?

A: Both packages use three-pin configurations with identical functional pin assignments: Base, Collector, and Emitter. Pin numbering and functional connectivity are equivalent. Physical pin spacing and lead geometry differ significantly, requiring board-level redesign for substitution.
