Parameter Comparison

Engineering Selection Recommendations

The BC184LC_J35Z is classified as obsolete, which restricts long-term availability and supply chain reliability. The substitute part 500-00001 is classified as active, ensuring continued availability and manufacturing support.

Substitution Basis:

The 500-00001 meets or exceeds all electrical specifications of the BC184LC_J35Z:

• Collector current rating is equal (200 mA)
• Collector-emitter breakdown voltage exceeds the original specification (40 V vs. 30 V)
• Power dissipation rating exceeds the original specification (1.5 W vs. 625 mW)
• Transition frequency exceeds the original specification (300 MHz vs. 150 MHz)
• Through-hole mounting type is identical
• TO-92 package is mechanically compatible with TO-92-3 footprints

Both parts carry ECCN classification EAR99 and are subject to REACH compliance requirements. The 500-00001 operates across an extended temperature range (−55°C to 150°C) compared to the BC184LC_J35Z operating temperature maximum of 150°C.

For applications requiring the exact electrical characteristics of the BC184LC_J35Z, the 500-00001 provides enhanced performance margins and active product status, making it suitable for direct substitution in existing designs.

Frequently Asked Questions (FAQ)

Q: Can the 500-00001 be used as a direct replacement for the BC184LC_J35Z?

A: Yes. The 500-00001 meets all electrical and mechanical requirements for substitution. Both devices are NPN transistors with identical collector current ratings (200 mA), compatible through-hole TO-92 packaging, and the 500-00001 exceeds the voltage and power specifications of the BC184LC_J35Z.

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

A: The 500-00001 provides enhanced specifications: 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 active product status versus obsolete status. The 500-00001 also features lower saturation voltage (300 mV vs. 600 mV) at specified test conditions.

Q: Are the packages physically compatible?

A: Yes. Both devices use through-hole TO-92 package configurations with formed leads. The TO-92-3 (TO-226AA) package of the BC184LC_J35Z and the TO-92 (TO-226) package of the 500-00001 are mechanically compatible with standard through-hole PCB layouts designed for TO-92 transistors.

Q: What is the impact of the higher transition frequency in the 500-00001?

A: The 500-00001 operates at 300 MHz compared to the BC184LC_J35Z at 150 MHz. This higher transition frequency provides improved high-frequency performance and faster switching characteristics, making the 500-00001 suitable for applications requiring higher-speed operation without compromising compatibility with designs originally specified for the BC184LC_J35Z.

Q: Does the lower saturation voltage of the 500-00001 affect circuit operation?

A: The 500-00001 exhibits lower saturation voltage (300 mV at 5 mA, 50 mA) compared to the BC184LC_J35Z (600 mV at 5 mA, 100 mA). This lower saturation voltage reduces power dissipation in switching applications and improves switching efficiency, representing an enhancement over the original specification.

Q: Is the 500-00001 available for long-term supply?

A: Yes. The 500-00001 is classified as active product status, ensuring ongoing manufacturing and availability. The BC184LC_J35Z is classified as obsolete, making the 500-00001 the recommended choice for new designs and ongoing production support.

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

A: Both parts carry ECCN classification EAR99 and are subject to REACH compliance. The 500-00001 provides extended operating temperature range (−55°C to 150°C) compared to the BC184LC_J35Z maximum of 150°C, offering greater flexibility for temperature-sensitive applications.
