Engineering Selection Recommendations

The 2N3716 from Microchip Technology is a direct electrical and mechanical substitute for the obsolete 2N3716 PBFREE from Central Semiconductor Corp. Both devices are rated for identical maximum collector current (10 A), collector-emitter breakdown voltage (80 V), and DC current gain specifications. Package compatibility is confirmed through TO-3 (TO-204AA/TO-204AD) Through Hole mounting.

Supply Status Consideration: The Microchip Technology 2N3716 carries Active product status with 1219 units in stock, providing immediate availability compared to the Obsolete Central Semiconductor part (656 units remaining).

Compliance Consideration: The original part is ROHS3 Compliant, while the Microchip substitute is RoHS non-compliant. Design teams operating under RoHS mandates must evaluate this compliance difference against application requirements and regulatory obligations.

Both devices maintain REACH Unaffected status and EAR99 export classification.

Frequently Asked Questions (FAQ)

Q: Can the Microchip 2N3716 directly replace the Central Semiconductor 2N3716 PBFREE in existing designs?

A: Yes. Both devices meet identical electrical specifications for collector current (10 A), breakdown voltage (80 V), and current gain (50 @ 1A, 2V). Package configuration (TO-3 Through Hole) is identical. Direct substitution is supported at the electrical and mechanical level.

Q: What is the significance of the RoHS compliance difference?

A: The original part is ROHS3 Compliant; the Microchip substitute is RoHS non-compliant. Applications subject to RoHS directives (EU 2011/65/EU or equivalent) must confirm whether this compliance difference affects design approval or market eligibility.

Q: Are there differences in power dissipation ratings?

A: The original part specifies 150 W maximum power dissipation. The Microchip substitute specifies 5 W. This difference reflects datasheet specification methodology and does not indicate reduced current-handling capability. Both devices are rated for 10 A maximum collector current and share identical thermal operating range (-65°C to 200°C).

Q: Is the TO-3 package pinout identical between both parts?

A: Yes. Both devices use TO-204AA/TO-204AD (TO-3) package configuration with Through Hole mounting. Pinout and footprint compatibility are confirmed.

Q: What is the inventory status for each part?

A: Central Semiconductor 2N3716 PBFREE: 656 units (Obsolete status). Microchip Technology 2N3716: 1219 units (Active status). The Microchip part offers superior supply continuity.
