Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BC559C,116 is determined by strict electrical and mechanical parameter matching within the PNP bipolar junction transistor category. The following parameters establish the substitution criteria:

Critical Matching Parameters:

• Transistor Type: PNP
• Current - Collector (Ic) (Max): 100 mA
• Voltage - Collector Emitter Breakdown (Max): 30 V
• Vce Saturation (Max) @ Ib, Ic: 650 mV @ 5 mA, 100 mA
• Current - Collector Cutoff (Max): 15 nA
• Power - Max: 500 mW
• Operating Temperature (TJ): 150 °C
• Mounting Type: Through Hole
• Package / Case: TO-92-3

Allowable Parameter Variations:

• Frequency - Transition: Equal to or greater than 100 MHz
• DC Current Gain (hFE) (Min) @ Ic, Vce: Equal to or greater than 200 @ 2 mA, 5 V
• Product Status: Active status preferred for ongoing availability

Substitute parts must maintain electrical compatibility across all critical parameters while meeting or exceeding performance specifications in frequency and current gain characteristics.

Engineering Selection Recommendations

BC559CTA (onsemi) - Direct Equivalent

The BC559CTA is a direct electrical and mechanical equivalent to the BC559C,116. This substitute maintains all critical electrical parameters including collector current, breakdown voltage, saturation voltage, and power dissipation. The BC559CTA offers improved frequency performance at 150 MHz compared to the original 100 MHz specification, providing enhanced capability for high-frequency applications. The part carries Active product status, ensuring long-term availability and supply chain continuity. Full RoHS3 compliance and REACH Unaffected status align with the original part's regulatory requirements.

BC559BTA (onsemi) - Manufacturer Recommended Substitute

The BC559BTA is designated as the manufacturer-recommended substitute for the BC559C,116. This part maintains all critical electrical parameters with the exception of DC Current Gain (hFE), which specifies a minimum of 200 @ 2 mA, 5 V compared to the original 420 specification. This reduced gain specification remains within acceptable operating parameters for general-purpose switching and amplification applications. The BC559BTA provides 150 MHz transition frequency, exceeding the original specification. Active product status and full regulatory compliance (RoHS3, REACH Unaffected) support production continuity.

Both substitute parts are suitable for direct replacement in applications where the BC559C,116 was originally specified, provided that circuit design accommodates the specified electrical parameters.

Frequently Asked Questions (FAQ)

Q: Can the BC559CTA and BC559BTA be used interchangeably with the BC559C,116?

A: Both parts are electrically and mechanically compatible with the BC559C,116 within the specified parameter ranges. The BC559CTA provides identical DC Current Gain specifications, while the BC559BTA operates with a reduced minimum gain of 200 versus 420. Selection depends on circuit gain requirements.

Q: What is the primary difference between the BC559CTA and BC559BTA?

A: The primary difference is DC Current Gain (hFE) specification. The BC559CTA maintains the original minimum gain of 420 @ 2 mA, 5 V, while the BC559BTA specifies a minimum gain of 200 @ 2 mA, 5 V. Both parts share identical maximum ratings and frequency performance.

Q: Are the substitute parts available in the same package as the original BC559C,116?

A: Yes. Both BC559CTA and BC559BTA are supplied in the TO-92-3 Through Hole package with formed leads, matching the original part's mechanical specifications.

Q: Do the substitute parts meet the same regulatory requirements as the BC559C,116?

A: Yes. Both BC559CTA and BC559BTA are ROHS3 Compliant and REACH Unaffected, matching the regulatory status of the original part.

Q: Why is the BC559C,116 listed as Obsolete?

A: The BC559C,116 carries Obsolete product status from the original manufacturer. The substitute parts BC559CTA and BC559BTA, both manufactured by onsemi with Active status, provide equivalent functionality with assured long-term availability.

Q: Can I use the BC559BTA if my circuit requires the higher gain specification of the BC559C,116?

A: The BC559BTA's minimum gain of 200 @ 2 mA, 5 V is lower than the original 420 specification. Circuit performance depends on specific gain requirements. If the application requires the higher gain, the BC559CTA is the appropriate selection.

Q: Are there any frequency limitations when substituting these parts?

A: Both substitute parts operate at 150 MHz transition frequency, exceeding the original 100 MHz specification. This enhanced frequency performance supports applications requiring higher switching speeds without limitation.
