2N3809 Equivalent & Substitute Parts

Part Overview

The 2N3809 is a dual PNP bipolar junction transistor (BJT) array manufactured by Central Semiconductor Corp, housed in a TO-78-6 metal can package. This component is rated for 60V collector-emitter breakdown voltage and 50mA maximum collector current, with a maximum power dissipation of 600mW. The 2N3809 is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement.

Substitute Part Grouping Explanation

Substitution of the 2N3809 is based on strict electrical and mechanical parameter matching within the dual PNP BJT category. The substitute parts 2N3810, 2N3810L, and 2N3810U are qualified as direct equivalents based on the following criteria:

Critical Matching Parameters:

• Transistor configuration: 2 PNP (Dual) array
• Maximum collector current: 50mA
• Maximum collector-emitter breakdown voltage: 60V
• Package type: TO-78-6 Metal Can
• Mounting method: Through Hole

All substitute parts maintain identical mechanical compatibility and core electrical ratings. The 2N3810 series parts are manufactured by Microchip Technology and carry active product status, ensuring long-term availability and supply chain continuity.

Parameter Comparison

Engineering Selection Recommendations

The 2N3810, 2N3810L, and 2N3810U are direct substitutes for the obsolete 2N3809 dual PNP BJT array. Selection among these three variants is based on product availability and procurement requirements:

2N3810: Base variant with 1595 units in stock. Suitable for standard applications requiring dual PNP functionality within the specified electrical parameters.

2N3810L: Low-gain variant with 846 units in stock. Functionally equivalent to 2N3810 with identical electrical specifications.

2N3810U: Upper-grade variant with 942 units in stock. Functionally equivalent to 2N3810 with identical electrical specifications.

All three substitute parts maintain the same TO-78-6 through-hole package, ensuring direct mechanical compatibility with existing PCB designs. The transition from the obsolete 2N3809 to any of these active Microchip Technology parts ensures continued supply chain access and long-term component availability.

All substitute parts carry identical RoHS non-compliance status and REACH unaffected classification as the original 2N3809, maintaining regulatory consistency in legacy system designs.

Frequently Asked Questions (FAQ)

Q: Can the 2N3810 series directly replace the 2N3809 in existing designs?

A: Yes. The 2N3810, 2N3810L, and 2N3810U are direct mechanical and electrical substitutes. Both the original and substitute parts use the TO-78-6 metal can package with identical pinout and footprint. Maximum collector current (50mA) and collector-emitter breakdown voltage (60V) are identical across all parts.

Q: What is the difference between 2N3810, 2N3810L, and 2N3810U?

A: All three variants are functionally equivalent with identical electrical ratings for collector current, voltage, saturation characteristics, and operating temperature range. Differences are designated by suffix letters (L and U) but do not affect substitution compatibility. Selection is based on inventory availability and procurement preference.

Q: Are there electrical differences between the 2N3809 and 2N3810 series?

A: The substitute parts have lower maximum power dissipation (350mW versus 600mW for the 2N3809) and lower minimum DC current gain (150 versus 300 at 1mA, 5V). However, both ratings remain within acceptable ranges for dual PNP BJT applications. The substitute parts provide additional specification data including saturation voltage and collector cutoff current, which were not specified for the original 2N3809.

Q: Is the package compatibility guaranteed?

A: Yes. Both the 2N3809 and all substitute parts use the TO-78-6 metal can package for through-hole mounting. Pin configuration and mechanical dimensions are identical, ensuring direct PCB compatibility without layout modifications.

Q: What is the product status difference, and does it affect substitution?

A: The 2N3809 is classified as obsolete, while the 2N3810 series parts are active products. This difference makes substitution necessary for new procurement and ensures long-term supply chain continuity. Active product status guarantees ongoing manufacturing and availability from Microchip Technology.

Q: Are compliance certifications identical between the original and substitute parts?

A: Yes. Both the 2N3809 and 2N3810 series carry identical RoHS non-compliance status and REACH unaffected classification. Regulatory compliance profiles are consistent across all parts, maintaining design compliance in legacy systems.
