Engineering Selection Recommendations

The BC560BTA is an obsolete product. Direct substitution is available through two active equivalent parts: BC557BTA and BC557BTF, both manufactured by onsemi.

BC557BTA and BC557BTF are parametrically identical to the BC560BTA across all electrical and mechanical specifications. Both substitute parts are classified as Active products, ensuring continued availability and supply chain stability.

Both substitute parts carry ROHS3 compliance certification, meeting current environmental and regulatory requirements. The REACH Unaffected status is maintained across all three parts, confirming consistent regulatory standing.

The primary distinction between the two substitute options is packaging format: BC557BTA is supplied in Cut Tape (CT) format, while BC557BTF is also supplied in Cut Tape (CT) format. Both are compatible with Through Hole assembly processes and utilize identical TO-92-3 package geometry.

Selection between BC557BTA and BC557BTF should be based on procurement requirements, inventory availability, and supply chain preferences, as electrical and mechanical performance are equivalent.

Frequently Asked Questions (FAQ)

Q: Can BC557BTA or BC557BTF be used as direct replacements for BC560BTA?

A: Yes. BC557BTA and BC557BTF are direct functional equivalents. All electrical parameters, including collector current, breakdown voltage, saturation voltage, current gain, power rating, and transition frequency, are identical. Package configuration and Through Hole mounting type are also identical.

Q: What is the difference between BC557BTA and BC557BTF?

A: Both parts are electrically and mechanically identical. The difference is in packaging format: both are supplied in Cut Tape (CT) format. Selection should be based on procurement and assembly requirements.

Q: Why is the BC560BTA listed as obsolete?

A: The BC560BTA has been discontinued by the manufacturer. However, equivalent active products are available as direct replacements with no design modifications required.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both BC557BTA and BC557BTF are ROHS3 compliant, meeting current environmental standards. The original BC560BTA RoHS status was not specified in available documentation.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes. All three parts use identical TO-92-3 Through Hole package geometry with formed leads. No PCB layout modifications are required when substituting BC557BTA or BC557BTF for BC560BTA.

Q: What are the key electrical parameters that define substitution compatibility?

A: Substitution compatibility is determined by: PNP transistor type, 100 mA maximum collector current, 45 V collector-emitter breakdown voltage, 650 mV saturation voltage at specified conditions, 200 minimum DC current gain, 500 mW power rating, and 150 MHz transition frequency.

Q: Are there any regulatory or compliance differences between the parts?

A: All three parts maintain REACH Unaffected status and EAR99 export classification. BC557BTA and BC557BTF carry ROHS3 compliance certification, ensuring compliance with current environmental regulations.
