Substitute Part Grouping Explanation

Substitution of the 2N6387 is determined by electrical and mechanical parameter equivalence. The critical parameters governing substitution are:

• Transistor Type: NPN - Darlington configuration
• Current Rating: 10 A maximum collector current
• Voltage Rating: 60 V maximum collector-emitter breakdown voltage
• Power Dissipation: 2 W maximum
• DC Current Gain: 1000 minimum at specified conditions
• Package: TO-220-3 through-hole form factor
• Saturation Characteristics: 3 V maximum at specified base and collector currents

The 2N6387G is a direct electrical and mechanical equivalent that maintains all specified electrical parameters while offering improved product status and compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The 2N6387G is the direct substitute for the 2N6387. All electrical parameters, mechanical dimensions, and thermal characteristics are identical. The 2N6387G offers two significant advantages:

1. Product Status: The 2N6387G maintains active product status, ensuring long-term availability and supply chain continuity compared to the obsolete 2N6387.

2. Regulatory Compliance: The 2N6387G is ROHS3 compliant, meeting current environmental and regulatory requirements. The original 2N6387 is RoHS non-compliant, which may restrict use in regulated applications and markets.

Both parts maintain REACH Unaffected status and EAR99 export classification. The 2N6387G is supplied in tube packaging, whereas packaging information for the 2N6387 is not specified. For new designs and procurement, the 2N6387G is the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Can the 2N6387G be used as a direct replacement for the 2N6387?

A: Yes. The 2N6387G is electrically and mechanically identical to the 2N6387. All electrical parameters, including current rating, voltage rating, power dissipation, gain characteristics, and saturation voltage, are equivalent. The TO-220-3 package and through-hole mounting are identical.

Q: What is the primary reason to transition from 2N6387 to 2N6387G?

A: The 2N6387 is obsolete, while the 2N6387G is active. Additionally, the 2N6387G is ROHS3 compliant, whereas the 2N6387 is RoHS non-compliant. These factors make the 2N6387G the appropriate choice for current and future applications.

Q: Are there any differences in thermal performance between these parts?

A: No. Both parts operate across the same temperature range of -65°C to 150°C (TJ) and have identical power dissipation ratings of 2 W.

Q: Will the 2N6387G function in existing circuit designs using the 2N6387?

A: Yes. The 2N6387G maintains identical electrical characteristics and pin configuration. No circuit modifications are required.

Q: What is the difference in packaging between the 2N6387 and 2N6387G?

A: The 2N6387G is supplied in tube packaging. The original 2N6387 packaging format is not specified in available documentation. Both use the TO-220-3 package form factor for mounting.

Q: Are both parts compliant with REACH regulations?

A: Yes. Both the 2N6387 and 2N6387G are classified as REACH Unaffected.
