KSP2907ACBU Equivalent & Substitute Parts

Part Overview

The KSP2907ACBU is a PNP bipolar junction transistor manufactured by onsemi, rated for 60 V collector-emitter breakdown voltage and 600 mA maximum collector current in a TO-92-3 through-hole package. This component is classified as obsolete, necessitating identification of active equivalent and substitute parts for ongoing design requirements and procurement needs. Substitute parts maintain electrical and mechanical compatibility while offering active product status and improved availability.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the KSP2907ACBU are classified into two categories based on electrical parameter alignment:

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

Enhanced Current Capability Substitute (PN2907ABU) provides 800 mA maximum collector current while maintaining all other electrical parameters at or above the KSP2907ACBU specification. This part is suitable for applications requiring higher current capacity within the same voltage and power envelope.

All substitute parts share the following critical parameters with the main part:

• PNP transistor type
• 60 V collector-emitter breakdown voltage
• 625 mW maximum power dissipation
• 200 MHz transition frequency
• TO-92-3 through-hole package
• 1.6 V maximum saturation voltage

Engineering Selection Recommendations

For Direct Replacement (Parametric Equivalents):

KSP2907ABU (Fairchild Semiconductor) and PN2907A PBFREE (Central Semiconductor Corp) are parametric equivalents with identical electrical specifications to the KSP2907ACBU. Both parts are active products with full compliance certifications. KSP2907ABU maintains the same manufacturer lineage as the original part. PN2907A PBFREE offers extended operating temperature range (-65°C to 150°C) and RoHS3 compliance, providing additional environmental robustness for applications requiring wider temperature operation.

For Enhanced Current Capability:

PN2907ABU (onsemi) provides 800 mA maximum collector current, a 33% increase over the KSP2907ACBU specification, while maintaining all other electrical parameters. This part is suitable for applications where the original 600 mA rating is marginal. PN2907ABU is an active product with RoHS3 compliance and extended operating temperature range (-55°C to 150°C).

Selection Criteria:

All substitute parts are pin-compatible with the KSP2907ACBU in TO-92-3 through-hole packages. Selection should prioritize active product status and compliance certifications. PN2907ABU is recommended for new designs requiring higher current capacity. KSP2907ABU or PN2907A PBFREE are recommended for direct replacement in existing applications. PN2907A PBFREE is recommended for applications requiring extended low-temperature operation.

Frequently Asked Questions (FAQ)

Q: Can PN2907ABU be used as a direct replacement for KSP2907ACBU?

A: PN2907ABU is electrically compatible with KSP2907ACBU for all critical parameters except maximum collector current. PN2907ABU provides 800 mA versus 600 mA for the KSP2907ACBU. In applications operating below 600 mA, PN2907ABU functions as a direct replacement with enhanced current margin. Pin configuration and package are identical.

Q: What is the difference between KSP2907ABU and PN2907A PBFREE?

A: Both parts are parametric equivalents with identical electrical specifications. KSP2907ABU is manufactured by Fairchild Semiconductor, while PN2907A PBFREE is manufactured by Central Semiconductor Corp. PN2907A PBFREE offers extended minimum operating temperature (-65°C versus unspecified for KSP2907ABU) and explicit RoHS3 compliance certification. Selection depends on supply chain preference and temperature range requirements.

Q: Are all substitute parts available in the same TO-92-3 package?

A: All substitute parts listed are supplied in TO-92-3 through-hole packages with identical pin configuration. No package conversion or PCB modification is required for substitution.

Q: Why is the KSP2907ACBU classified as obsolete?

A: The KSP2907ACBU is listed as obsolete by the manufacturer. Active equivalent parts are available from multiple manufacturers with identical or enhanced specifications, ensuring continued design support and procurement availability.

Q: What is the significance of RoHS3 compliance for substitute parts?

A: RoHS3 compliance indicates conformance to Restriction of Hazardous Substances regulations. PN2907ABU and PN2907A PBFREE carry explicit RoHS3 certification, meeting environmental and regulatory requirements for applications subject to these standards.

Q: Can PN2907A PBFREE operate at lower temperatures than the original KSP2907ACBU?

A: PN2907A PBFREE is rated for -65°C minimum operating temperature, compared to the KSP2907ACBU with unspecified minimum temperature. This extended range supports applications requiring operation in cold environments or wide temperature cycling.

Q: What does "PBFREE" designation indicate in PN2907A PBFREE?

A: PBFREE indicates lead-free manufacturing, confirming compliance with RoHS directives that restrict lead and other hazardous substances in electronic components.
