Equivalent & Substitute Parts for 2SD09660R

Part Overview

The 2SD09660R is an NPN bipolar junction transistor manufactured by Panasonic Electronic Components, designed for general-purpose switching and amplification applications. This device features a maximum collector current of 5 A, collector-emitter breakdown voltage of 20 V, and a maximum power dissipation of 1 W in a Through Hole TO-92L-A1 package.

The 2SD09660R is classified as an obsolete product. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or repair requirements for legacy systems utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2SD09660R requires evaluation against the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Transistor Type: Must be NPN
• Frequency - Transition: Must equal or exceed 150 MHz
• Power - Max: Must equal or exceed 1 W
• Current - Collector (Ic) (Max): Must equal or exceed 5 A
• Voltage - Collector Emitter Breakdown (Max): Must equal or exceed 20 V

Mechanical Compatibility Criteria:

• Mounting Type: Must be Through Hole
• Package / Case: Must be compatible with TO-92 form factor or equivalent

The ZTX692B does not meet the electrical substitution criteria for the 2SD09660R. The ZTX692B has a maximum collector current of 1 A, which is insufficient for applications requiring the 5 A capability of the 2SD09660R. Although the ZTX692B exceeds the voltage and frequency specifications, the current rating deficiency makes it unsuitable as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The ZTX692B is not recommended as a direct substitute for the 2SD09660R in applications requiring the full 5 A collector current specification. The ZTX692B maximum collector current rating of 1 A represents a 80% reduction in current-handling capability compared to the 2SD09660R.

The ZTX692B is suitable only for applications where the circuit design can operate within a 1 A maximum collector current envelope. In such cases, the ZTX692B offers the advantage of active product status and ROHS3 compliance, compared to the obsolete and RoHS non-compliant status of the 2SD09660R.

For applications requiring the full 5 A current capability of the 2SD09660R, alternative NPN transistors with equivalent or superior current ratings, voltage ratings, and frequency response must be evaluated against the specified electrical and mechanical parameters.

Frequently Asked Questions (FAQ)

Q: Can the ZTX692B replace the 2SD09660R in all applications?

A: No. The ZTX692B has a maximum collector current of 1 A, while the 2SD09660R is rated for 5 A. The ZTX692B is suitable only for circuits designed to operate within 1 A maximum collector current limits.

Q: What is the primary limitation of using ZTX692B as a substitute?

A: The collector current rating. The ZTX692B maximum Ic of 1 A is insufficient for applications requiring the 5 A capability specified for the 2SD09660R.

Q: Are the packages physically compatible?

A: Both devices use Through Hole mounting in TO-92 form factor packages. The 2SD09660R uses TO-92L-A1 (Long Body), while the ZTX692B uses E-Line-3 (TO-92 compatible). Physical compatibility exists, but electrical specifications must be verified for the specific application.

Q: What are the compliance differences between these parts?

A: The 2SD09660R is RoHS non-compliant and obsolete. The ZTX692B is ROHS3 compliant and has active product status, making it preferable for new designs subject to RoHS requirements.

Q: Do both transistors have the same frequency response?

A: Yes. Both devices have a transition frequency of 150 MHz, meeting this specification equally.

Q: What should be done if a 5 A collector current is required?

A: Alternative NPN transistors with maximum collector current ratings of 5 A or greater must be evaluated. The ZTX692B does not meet this requirement and cannot be used as a substitute in such applications.
