MPS2907ARLRM Equivalent & Substitute Parts

Part Overview

The MPS2907ARLRM is a PNP bipolar junction transistor manufactured by onsemi, rated for 60 V collector-emitter breakdown voltage and 600 mA maximum collector current. This device is packaged in a TO-92 through-hole configuration and is classified as obsolete. Due to its obsolete status, equivalent and substitute parts from active product lines are necessary for new designs and ongoing production requirements. Substitute parts maintain electrical compatibility while offering improved availability and compliance with current regulatory standards.

Substitute Part Grouping Explanation

Substitute parts are classified into two categories based on electrical parameter alignment with the MPS2907ARLRM:

Direct Equivalents maintain identical electrical specifications across all critical parameters: 60 V collector-emitter breakdown voltage, 600 mA maximum collector current, 1.6 V Vce saturation, 10 nA collector cutoff current, 100 minimum DC current gain, 625 mW power dissipation, and 200 MHz transition frequency. These parts are pin-compatible and functionally interchangeable in all applications.

Similar Alternatives share the same voltage and frequency ratings but differ in maximum collector current (800 mA versus 600 mA) and collector cutoff current (20 nA versus 10 nA). These parts are suitable for applications where the higher current capability does not create design conflicts and where the increased cutoff current is acceptable.

All substitute parts maintain the TO-92-3 through-hole package configuration and are compatible with existing PCB layouts designed for the MPS2907ARLRM.

Engineering Selection Recommendations

For Direct Replacement (Identical Electrical Specifications):

KSP2907ACTA, KSP2907ATA, and KSP2907ATF are direct electrical equivalents to the MPS2907ARLRM. These parts maintain 600 mA maximum collector current and 10 nA collector cutoff current specifications. KSP2907ACTA is manufactured by onsemi and carries ROHS3 compliance certification, making it the preferred choice for new designs requiring regulatory compliance. KSP2907ATA and KSP2907ATF are manufactured by Fairchild Semiconductor and are available in active production status with high inventory levels.

For Applications Tolerating Higher Current Capability:

PN2907ATA, PN2907ATAR, PN2907ATF, and PN2907ATFR are suitable alternatives where the increased maximum collector current (800 mA) and collector cutoff current (20 nA) do not conflict with circuit design requirements. All onsemi variants (PN2907ATA, PN2907ATAR, PN2907ATFR) carry ROHS3 compliance certification. These parts are available in active production with substantial inventory levels.

Compliance Considerations:

The original MPS2907ARLRM is RoHS non-compliant. For applications subject to RoHS regulations, KSP2907ACTA, PN2907ATA, PN2907ATAR, and PN2907ATFR provide ROHS3-compliant alternatives. Fairchild Semiconductor variants do not specify RoHS status in the provided data.

Packaging and Availability:

All substitute parts are packaged in TO-92-3 through-hole configuration, compatible with existing PCB designs. Inventory availability is highest for PN2907ATF (56,113 units) and KSP2907ATF (40,379 units), followed by PN2907ATAR (27,888 units).

Frequently Asked Questions (FAQ)

Q: Can KSP2907ACTA be used as a direct replacement for MPS2907ARLRM?

A: Yes. KSP2907ACTA maintains identical electrical specifications: 600 mA maximum collector current, 60 V collector-emitter breakdown voltage, 1.6 V Vce saturation, 10 nA collector cutoff current, 100 minimum DC current gain, 625 mW power dissipation, and 200 MHz transition frequency. The TO-92-3 package is pin-compatible with the original part.

Q: What is the difference between KSP2907 and PN2907 series parts?

A: Both series share identical voltage, power, and frequency ratings. The primary difference is maximum collector current: KSP2907 variants are rated for 600 mA, while PN2907 variants are rated for 800 mA. PN2907 parts also specify 20 nA maximum collector cutoff current compared to 10 nA for KSP2907 parts. Both series are suitable for the MPS2907ARLRM application if the higher current capability is acceptable.

Q: Are all substitute parts RoHS compliant?

A: onsemi-manufactured substitutes (KSP2907ACTA, PN2907ATA, PN2907ATAR, PN2907ATFR) carry ROHS3 compliance certification. Fairchild Semiconductor variants (KSP2907ATA, KSP2907ATF, PN2907ATF) do not specify RoHS status in available documentation.

Q: Can PN2907 parts be used in applications designed for 600 mA maximum current?

A: Yes. PN2907 parts are rated for 800 mA maximum collector current, which exceeds the 600 mA requirement. The higher current rating does not create incompatibility; the circuit will operate within the part's safe operating area. However, if the application circuit is designed with current-limiting components based on 600 mA assumptions, no circuit modification is required.

Q: What is the difference between Cut Tape and Bulk packaging?

A: Cut Tape (CT) packaging provides components on continuous tape suitable for automated pick-and-place assembly. Bulk packaging provides loose components. Both packaging types contain identical electrical components; the difference is in handling and assembly method. Select based on manufacturing process requirements.

Q: Are there temperature range differences between substitute parts?

A: All substitute parts maintain the -55°C to 150°C operating temperature range specified for the MPS2907ARLRM. No temperature derating is required when substituting between these parts.

Q: Which substitute part offers the best inventory availability?

A: PN2907ATF (Fairchild Semiconductor) offers the highest inventory level at 56,113 units, followed by KSP2907ATF at 40,379 units. Both parts are in active production status.
