Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2N4036 W/GOLD is determined by the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Transistor Type: PNP configuration
• Voltage Rating: Collector-Emitter breakdown voltage must equal or exceed 65V
• Current Rating: Maximum collector current must equal or exceed 1A
• Power Dissipation: Maximum power rating must support 800mW operation

Mechanical Compatibility Criteria:

• Package Type: TO-39 metal can (TO-205AD) through-hole configuration
• Pin Configuration: Standard three-pin BJT arrangement (Base, Collector, Emitter)

The 2N4033 qualifies as a direct substitute because it maintains identical package specifications (TO-39), exceeds the voltage rating (80V vs. 65V), matches the current rating (1A), and provides equivalent power dissipation (800mW). The PNP transistor type and through-hole mounting are preserved.

Engineering Selection Recommendations

The 2N4033 manufactured by Microchip Technology is the qualified substitute for the obsolete 2N4036 W/GOLD. Selection is based on the following factors:

Product Status: The 2N4036 W/GOLD is obsolete with no active manufacturing. The 2N4033 is actively produced, ensuring long-term availability and supply chain continuity.

Electrical Specifications: The 2N4033 meets or exceeds all critical electrical parameters. The 80V breakdown voltage rating provides a 15V margin above the 2N4036's 65V specification. Current and power ratings are identical at 1A and 800mW respectively.

Package Compatibility: Both devices use the TO-39 metal can package (TO-205AD designation) with through-hole mounting, ensuring direct physical and electrical compatibility in existing PCB layouts without modification.

Regulatory Compliance: Both parts maintain identical REACH and MSL classifications, with no additional compliance burden introduced by substitution.

Inventory Status: The 2N4033 has 9,672 pieces in stock, providing immediate availability compared to the limited 649 pieces of the obsolete 2N4036 W/GOLD.

Frequently Asked Questions (FAQ)

Q: Can the 2N4033 be used as a direct replacement for the 2N4036 W/GOLD without circuit modification?

A: Yes. The 2N4033 is a direct substitute. Both devices are PNP transistors in TO-39 packages with identical pin configurations. The 2N4033's higher voltage rating (80V vs. 65V) and matching current/power specifications ensure functional equivalence in circuits designed for the 2N4036 W/GOLD.

Q: What is the significance of the higher 80V rating on the 2N4033?

A: The 2N4033's 80V collector-emitter breakdown voltage exceeds the 2N4036 W/GOLD's 65V rating by 15V. This provides additional voltage margin and does not create incompatibility. The device will operate safely in any circuit designed for 65V operation.

Q: Are there any differences in DC current gain between these devices?

A: The 2N4033 specifies a minimum DC current gain (hFE) of 100 at 100mA collector current and 5V collector-emitter voltage. The 2N4036 W/GOLD specifications do not include hFE data in the provided parameters. Circuit designs should verify that the 2N4033's gain characteristics are acceptable for the intended application.

Q: What is the operating temperature range for the 2N4033?

A: The 2N4033 operates from -55°C to 200°C junction temperature. The 2N4036 W/GOLD operating temperature range is not specified in the provided data. Designs requiring operation outside the -55°C to 200°C range should be evaluated separately.

Q: Is the 2N4033 RoHS compliant?

A: The 2N4033 is RoHS non-compliant. Both the 2N4036 W/GOLD and 2N4033 maintain REACH Unaffected status and MSL 1 (Unlimited) classification, indicating no moisture sensitivity concerns for either device.

Q: What is the saturation voltage of the 2N4033?

A: The 2N4033 has a maximum saturation voltage (Vce sat) of 1V when operating at 100mA base current and 1A collector current. This specification is not provided for the 2N4036 W/GOLD.

Q: Are there any package or pinout differences between the 2N4036 W/GOLD and 2N4033?

A: No. Both devices use the TO-39 metal can package (TO-205AD) with identical three-pin through-hole configuration. No PCB layout modifications are required for substitution.
