DSA710100L Equivalent & Substitute Parts

Part Overview

The DSA710100L is a PNP bipolar junction transistor manufactured by Panasonic Electronic Components, designed for surface mount applications in the MiniP3-F2-B package. This component is rated for 80 V collector-emitter breakdown voltage with a maximum collector current of 500 mA and 1 W power dissipation. The part is currently discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives from active manufacturers to maintain design continuity and support ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DSA710100L is determined by strict adherence to the following electrical and mechanical parameters:

Critical Matching Parameters:

• Transistor polarity: PNP
• Voltage rating: 80 V collector-emitter breakdown (minimum)
• Current rating: Collector current capacity sufficient for 500 mA operation
• Package type: TO-243AA surface mount configuration
• Compliance: ROHS3 compliant

Allowable Parameter Variations: Substitute parts may exceed the original specifications in the following areas without compromising circuit compatibility:

• Maximum collector current (higher ratings acceptable)
• Power dissipation (higher ratings acceptable)
• Transition frequency (higher ratings acceptable)
• DC current gain (hFE) variations within normal manufacturing tolerances

The identified substitute parts (2SAR514P5T100 and 2SAR514PHZGT100) meet or exceed all critical parameters while maintaining electrical and mechanical compatibility with the original DSA710100L design.

Parameter Comparison

Engineering Selection Recommendations

2SAR514P5T100 (Rohm Semiconductor)

This substitute part is supplied in Cut Tape (CT) and Digi-Reel packaging. It maintains full electrical compatibility with the DSA710100L across all critical parameters. The part is currently in active production status with 6100 units in stock. The higher collector current rating (700 mA versus 500 mA) and increased transition frequency (380 MHz versus 120 MHz) provide design margin without introducing compatibility issues. ROHS3 compliance and MSL 1 rating match the original specification.

2SAR514PHZGT100 (Rohm Semiconductor)

This substitute part is supplied in Tape & Reel (TR) packaging and includes automotive-grade qualification (AEC-Q101). It provides identical electrical performance to the 2SAR514P5T100 with the addition of automotive qualification. This part is suitable for applications requiring automotive-grade components. The part is currently in active production status with 919 units in stock. ROHS3 compliance, REACH unaffected status, and MSL 1 rating are maintained.

Selection Criteria:

Choose 2SAR514P5T100 for standard industrial applications requiring standard packaging formats. Choose 2SAR514PHZGT100 for automotive applications or when AEC-Q101 qualification is required by design specifications.

Frequently Asked Questions (FAQ)

Q: Can the 2SAR514P5T100 or 2SAR514PHZGT100 be used as direct replacements for the DSA710100L?

A: Both Rohm parts are electrically and mechanically compatible with the DSA710100L. They share the same TO-243AA package configuration and meet or exceed all critical electrical parameters including voltage rating, collector current capacity, and operating temperature range.

Q: What is the difference between the two Rohm substitute parts?

A: The primary difference is packaging format and automotive qualification. The 2SAR514P5T100 is supplied in Cut Tape and Digi-Reel format, while the 2SAR514PHZGT100 is supplied in Tape & Reel format and includes AEC-Q101 automotive qualification. Electrical performance is identical between the two parts.

Q: Why do the substitute parts have higher power ratings than the original DSA710100L?

A: The substitute parts are rated for 500 mW maximum power dissipation compared to the original 1 W rating. This difference does not affect substitution compatibility. The original design should be evaluated to confirm that actual power dissipation in the application does not exceed 500 mW. If the application requires the full 1 W capability, alternative parts should be considered.

Q: Are there any package compatibility concerns when substituting these parts?

A: All three parts use the TO-243AA package configuration. The supplier device packages differ (MiniP3-F2-B for the original, MPT3 for the 2SAR514P5T100, and SOT-89 for the 2SAR514PHZGT100), but these are equivalent package designations for the same physical TO-243AA form factor. PCB footprints and land patterns are compatible.

Q: What is the significance of the higher transition frequency in the substitute parts?

A: The substitute parts have a transition frequency of 380 MHz compared to 120 MHz for the original. This higher frequency capability provides additional design margin for high-frequency applications and does not introduce compatibility issues in circuits designed for the lower frequency specification.

Q: Are both substitute parts currently available?

A: Yes. The 2SAR514P5T100 has 6100 units in stock, and the 2SAR514PHZGT100 has 919 units in stock. Both parts are in active production status.

Q: Do the substitute parts meet the same compliance requirements as the original?

A: Yes. Both substitute parts are ROHS3 compliant and have MSL 1 (Unlimited) moisture sensitivity rating, matching the original DSA710100L specification. The 2SAR514PHZGT100 additionally carries REACH unaffected status.
