• Voltage - Collector Emitter Breakdown: Minimum 120 V (equal or greater)
• Current - Collector (Ic) (Max): Minimum 200 mA (equal or greater)
• Power Dissipation: Minimum 625 mW (equal or greater)
• Operating Temperature Range: Must encompass -55°C to 150°C minimum

Mechanical Compatibility Criteria:

• Mounting Type: Through Hole required
• Package / Case: TO-92-3 compatible or E-Line (TO-92 compatible) form factor

All substitute parts listed are manufactured by Diodes Incorporated and maintain NPN configuration with through-hole mounting. Each substitute meets or exceeds the electrical specifications of the MPSL01_D26Z while offering active product status and RoHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: ZTX694BSTZ

The ZTX694BSTZ is the closest functional equivalent to the MPSL01_D26Z. It maintains the 120 V collector-emitter breakdown voltage specification and exceeds the 200 mA collector current requirement with 500 mA capability. The ZTX694BSTZ is manufactured by Diodes Incorporated with active product status and ROHS3 compliance. The E-Line (TO-92 compatible) package provides mechanical compatibility with through-hole mounting. Operating temperature range extends to 200°C, exceeding the MPSL01_D26Z requirement. This part is available in high inventory (25,200 pcs) in Cut Tape packaging.

Secondary Substitutes:

ZTX415STZ and ZTX453STZ are suitable for applications where 100 V collector-emitter breakdown voltage is acceptable. ZTX415STZ provides 500 mA current capability with avalanche mode operation. ZTX453STZ offers 1 A current capability with 150 MHz transition frequency. Both maintain through-hole mounting and active product status.

ZTX653STZ and ZTX853STZ are appropriate for high-current applications requiring collector currents of 2 A and 4 A respectively. These parts operate at 100 V breakdown voltage and are suitable only where voltage derating is acceptable.

All substitute parts carry ROHS3 compliance and REACH Unaffected status, meeting modern regulatory requirements. All are classified as EAR99 for export control purposes.

Frequently Asked Questions (FAQ)

Q: Can ZTX415STZ replace MPSL01_D26Z in all applications?

A: ZTX415STZ is suitable for applications where the 100 V collector-emitter breakdown voltage meets circuit requirements. The MPSL01_D26Z specifies 120 V breakdown, so ZTX415STZ represents a voltage derating. Current capability (500 mA) exceeds the MPSL01_D26Z requirement (200 mA). Verify circuit voltage margins before substitution.

Q: What is the difference between E-Line and TO-92-3 packaging?

A: E-Line (TO-92 compatible) and TO-92-3 are mechanically compatible three-lead through-hole packages with formed leads. Both mount identically on printed circuit boards. E-Line is the modern designation for this package form factor used by Diodes Incorporated.

Q: Why does ZTX694BSTZ have higher power dissipation than MPSL01_D26Z?

A: ZTX694BSTZ is rated for 1 W maximum power dissipation compared to 625 mW for MPSL01_D26Z. This reflects improved thermal design and higher current capability (500 mA vs. 200 mA). The higher rating does not require increased power consumption in equivalent circuit applications.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts listed carry ROHS3 Compliant status. The MPSL01_D26Z compliance status is not specified in available documentation.

Q: Which substitute part has the highest transition frequency?

A: ZTX653STZ offers the highest transition frequency at 175 MHz, followed by ZTX453STZ at 150 MHz. The MPSL01_D26Z operates at 60 MHz. Higher transition frequency provides improved high-frequency performance but is not required for direct substitution in DC or low-frequency applications.

Q: Can ZTX853STZ replace MPSL01_D26Z?

A: ZTX853STZ is electrically compatible for current and power requirements (4 A, 1.2 W) but operates at 100 V collector-emitter breakdown voltage. This represents a 20 V derating from the MPSL01_D26Z specification. Substitution is valid only where circuit design accommodates 100 V maximum voltage.

Q: What is the inventory status of substitute parts?

A: All substitute parts are in active production with substantial inventory availability. ZTX694BSTZ and ZTX453STZ have the highest inventory levels (25,200 pcs and 25,100 pcs respectively), ensuring supply continuity for production requirements.
