Key Parameters

Substitute Part Grouping Explanation

Substitution of the BC184LC_D27Z is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Transistor Type: NPN configuration
• Current - Collector (Ic) (Max): 200 mA or greater
• Voltage - Collector Emitter Breakdown (Max): 30 V or greater
• Mounting Type: Through Hole
• Package / Case: TO-92-3 or equivalent TO-226 variant

Performance Considerations:

• Power dissipation rating of 625 mW or greater
• Transition frequency of 150 MHz or greater
• Vce saturation characteristics suitable for switching applications
• DC current gain (hFE) sufficient for intended circuit operation

Substitute parts must meet or exceed the electrical specifications of the BC184LC_D27Z while maintaining physical and functional compatibility. The 500-00001 from Parallax Inc. satisfies these criteria with enhanced electrical performance across multiple parameters.

Engineering Selection Recommendations

BC184LC_D27Z (onsemi) — Obsolete Status: The BC184LC_D27Z is classified as obsolete, indicating that onsemi has discontinued manufacturing and support for this component. While inventory remains available (788 Pcs in stock), long-term supply cannot be guaranteed. This status necessitates evaluation of active substitute parts for new designs or ongoing production support.

500-00001 (Parallax Inc.) — Active Status: The 500-00001 is an active product with confirmed ongoing manufacturing and support. This part meets all mandatory electrical and mechanical compatibility requirements for the BC184LC_D27Z while providing enhanced performance specifications. The 500-00001 offers:

• Increased collector-emitter breakdown voltage (40 V vs. 30 V)
• Improved power dissipation capability (1.5 W vs. 625 mW)
• Higher transition frequency (300 MHz vs. 150 MHz)
• Lower saturation voltage (300 mV vs. 600 mV at specified conditions)
• Confirmed operating temperature range (-55°C to 150°C vs. 150°C maximum)

Both parts carry ECCN EAR99 classification and are REACH compliant. The 500-00001 is suitable for direct substitution in applications where the BC184LC_D27Z was previously specified, with the additional benefit of enhanced electrical performance and active product status.

Frequently Asked Questions (FAQ)

Q: Can the 500-00001 directly replace the BC184LC_D27Z in existing circuits?

A: Yes. The 500-00001 meets all mandatory electrical and mechanical compatibility criteria. Both devices are NPN transistors with identical maximum collector current (200 mA), compatible TO-92 packaging, and Through Hole mounting. The 500-00001 provides equal or superior performance across all specified parameters.

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

A: The primary differences are product status and enhanced electrical performance of the 500-00001. The 500-00001 features higher collector-emitter breakdown voltage (40 V vs. 30 V), greater power dissipation capability (1.5 W vs. 625 mW), higher transition frequency (300 MHz vs. 150 MHz), and lower saturation voltage. The BC184LC_D27Z is obsolete; the 500-00001 is active.

Q: Are the TO-92-3 and TO-92 packages physically identical?

A: Both packages are variants of the TO-226 standard and are physically compatible for Through Hole mounting applications. Pin configuration and lead spacing are equivalent, allowing direct mechanical substitution on printed circuit boards designed for TO-92-3 components.

Q: What is the significance of the lower saturation voltage in the 500-00001?

A: Lower saturation voltage (300 mV vs. 600 mV) indicates reduced voltage drop across the transistor when operating in saturation mode. This characteristic results in lower power dissipation in the transistor itself and improved efficiency in switching applications.

Q: Does the higher transition frequency of the 500-00001 affect circuit compatibility?

A: Higher transition frequency (300 MHz vs. 150 MHz) indicates faster switching capability. This enhancement does not negatively impact circuits designed for the BC184LC_D27Z. The 500-00001 remains compatible with applications operating at or below 150 MHz and provides additional performance margin for higher-frequency applications.

Q: Are there compliance or regulatory differences between these parts?

A: Both parts carry identical ECCN EAR99 classification and are REACH compliant. No regulatory or compliance barriers exist to substitution.

Q: Why is the BC184LC_D27Z obsolete?

A: Obsolescence is a manufacturer decision reflecting end-of-life status for the product line. onsemi has discontinued production and support. The 500-00001 from Parallax Inc. provides an active alternative with equivalent or superior functionality.
