Key Parameters

Substitute Part Grouping Explanation

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

Critical Matching Parameters:

• Transistor polarity: PNP
• Package type: TO-92-3 (Through Hole)
• Collector-emitter breakdown voltage: 60 V (minimum requirement)
• Maximum collector current: Equal to or greater than 600 mA
• Operating temperature range: Must encompass or exceed -55°C to 150°C
• RoHS compliance status

Allowable Variation Parameters:

• Maximum power dissipation: Equal to or greater than 625 mW
• DC current gain (hFE): May differ from the original specification
• Transition frequency: May differ from the original specification
• Collector cutoff current: May differ from the original specification
• Vce saturation voltage: May differ from the original specification

The KSA708YBU meets all critical matching parameters and is classified as an active product with superior electrical performance in several categories, making it a valid substitute for the obsolete MPS2907A-H-BP.

Engineering Selection Recommendations

MPS2907A-H-BP (Original Part): The MPS2907A-H-BP is obsolete and no longer in active production. However, 1086 pieces remain available as new original stock. Selection of the original part is appropriate only when existing inventory is accessible and when the specific electrical characteristics (200 MHz transition frequency, 200 hFE minimum gain) are critical to circuit performance.

KSA708YBU (Substitute Part): The KSA708YBU is an active product manufactured by Fairchild Semiconductor with 91001 pieces in stock. It is RoHS compliant and meets all critical electrical and mechanical substitution criteria. The KSA708YBU provides superior maximum collector current (700 mA vs. 600 mA) and power dissipation (800 mW vs. 625 mW), making it suitable for applications requiring equal or greater current handling capacity.

The KSA708YBU operates at a lower transition frequency (50 MHz vs. 200 MHz) and exhibits different DC current gain characteristics. These differences are acceptable for low-frequency switching applications and general-purpose amplification circuits where the original 200 MHz specification is not a functional requirement.

The KSA708YBU's maximum operating temperature is specified as 150°C (junction temperature), which matches the upper limit of the MPS2907A-H-BP but does not explicitly specify the lower temperature limit. For applications requiring operation below 0°C, verification of the KSA708YBU's low-temperature performance is necessary.

Frequently Asked Questions (FAQ)

Q: Can the KSA708YBU directly replace the MPS2907A-H-BP in all applications?

A: The KSA708YBU is mechanically and electrically compatible for most applications. Both devices are PNP transistors in TO-92-3 packages with identical 60 V collector-emitter breakdown voltage. The KSA708YBU provides higher current and power ratings. However, applications specifically designed around the MPS2907A-H-BP's 200 MHz transition frequency or 200 hFE minimum gain may require circuit evaluation. Low-temperature operation below -55°C requires confirmation of KSA708YBU specifications.

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

A: The primary differences are: (1) Product status—MPS2907A-H-BP is obsolete; KSA708YBU is active; (2) Transition frequency—MPS2907A-H-BP operates at 200 MHz; KSA708YBU at 50 MHz; (3) Maximum ratings—KSA708YBU exceeds the original in collector current (700 mA vs. 600 mA) and power dissipation (800 mW vs. 625 mW); (4) DC current gain—measured at different test conditions; (5) Collector cutoff current—KSA708YBU is higher (100 nA vs. 50 nA).

Q: Are both parts RoHS compliant?

A: Yes. The MPS2907A-H-BP is RoHS compliant. The KSA708YBU is also RoHS compliant. Both parts meet environmental compliance requirements for restricted substance use.

Q: What is the moisture sensitivity level (MSL) of the KSA708YBU?

A: The moisture sensitivity level for the KSA708YBU is not provided in the available technical data. Contact the manufacturer or authorized distributor for MSL classification if moisture-sensitive handling procedures are required for your manufacturing process.

Q: Can I use the KSA708YBU in high-frequency switching applications?

A: The KSA708YBU's 50 MHz transition frequency is suitable for audio-frequency and low-frequency RF applications. Applications requiring switching speeds above 50 MHz should use the original MPS2907A-H-BP (200 MHz) or identify alternative parts with higher transition frequency specifications.

Q: What is the minimum operating temperature for the KSA708YBU?

A: The KSA708YBU datasheet specifies a maximum operating temperature of 150°C but does not explicitly state the minimum temperature limit in the provided technical parameters. The MPS2907A-H-BP operates from -55°C to 150°C. For applications requiring low-temperature operation, obtain the complete KSA708YBU datasheet or contact the manufacturer for confirmation of minimum operating temperature.
