Key Parameters

Substitute Part Grouping Explanation

Substitution of the PBLS4005V,115 is determined by the following critical parameters:

Functional Requirements:

• Transistor configuration: 1 NPN pre-biased and 1 PNP transistor in single package
• Internal base resistor values: 47kOhms (R1 and R2)
• Maximum collector current ratings: 100mA (NPN), 500mA (PNP)
• Collector-emitter breakdown voltage: minimum 50V (NPN), 40V (PNP)

Electrical Performance:

• DC current gain (hFE) specifications at defined operating points
• Saturation voltage characteristics
• Collector cutoff current
• Transition frequency (where specified)
• Maximum power dissipation: 300mW or greater

Physical & Compliance Requirements:

• Surface mount technology
• RoHS3 compliance
• MSL rating of 1 (Unlimited)
• REACH unaffected status

Substitute parts must meet or exceed all specified electrical parameters and maintain compatibility with the original package footprint or accept an alternative surface mount package suitable for the application.

Engineering Selection Recommendations

PBLS4005Y,115 (Nexperia USA Inc.)

The PBLS4005Y,115 is the primary recommended substitute for the PBLS4005V,115. This part maintains identical electrical specifications including collector current ratings (100mA, 500mA), collector-emitter breakdown voltages (50V, 40V), internal resistor values (47kOhms), DC current gain characteristics, and saturation voltage performance. Both parts share the same base product number (PBLS4005) and are manufactured to the same electrical standards.

The PBLS4005Y,115 carries an active product status, ensuring ongoing availability and manufacturing support. It is packaged in 6-TSSOP format with tape and reel packaging, providing a direct functional equivalent. All compliance certifications match the original part: ROHS3 compliant, MSL 1 (Unlimited), and REACH unaffected. The package footprint differs (6-TSSOP versus SOT-666), requiring PCB layout verification but presenting no electrical incompatibility.

EMF5XV6T5G (onsemi)

The EMF5XV6T5G is a secondary substitute option manufactured by onsemi. This part maintains the same transistor configuration (1 NPN pre-biased, 1 PNP), collector current ratings (100mA, 500mA), and internal resistor values (47kOhms). The NPN collector-emitter breakdown voltage matches at 50V; however, the PNP breakdown voltage is specified at 12V compared to 40V in the original part, representing a reduced voltage rating for the PNP transistor.

The EMF5XV6T5G offers improved power dissipation capability (500mW versus 300mW) and superior collector cutoff current performance (500nA versus 1µA). The transition frequency specification is not provided for this part. The EMF5XV6T5G is packaged in SOT-563 format, differing from both the original SOT-666 and the PBLS4005Y,115 6-TSSOP package. This part carries obsolete product status. All compliance certifications are equivalent: ROHS3 compliant, MSL 1 (Unlimited), and REACH unaffected.

Selection between PBLS4005Y,115 and EMF5XV6T5G depends on application voltage requirements for the PNP transistor and package compatibility with existing PCB designs.

Frequently Asked Questions (FAQ)

Q: Can the PBLS4005Y,115 be used as a direct replacement for the PBLS4005V,115 without circuit modification?

A: The PBLS4005Y,115 is electrically equivalent to the PBLS4005V,115 across all specified parameters. However, the package format differs (6-TSSOP versus SOT-666). PCB layout and footprint must be verified for compatibility. If the original PCB is designed for SOT-666, the 6-TSSOP package requires a different footprint pattern. No circuit modifications are required if the package footprint is accommodated.

Q: What is the significance of the PNP collector-emitter breakdown voltage difference between the PBLS4005V,115 (40V) and EMF5XV6T5G (12V)?

A: The PNP breakdown voltage specification defines the maximum voltage that can be applied between the collector and emitter of the PNP transistor without risk of junction breakdown. The PBLS4005V,115 and PBLS4005Y,115 both support 40V on the PNP transistor. The EMF5XV6T5G limits this to 12V. Applications requiring PNP operation above 12V must use PBLS4005Y,115 or the original PBLS4005V,115. Applications operating the PNP transistor at 12V or below can use EMF5XV6T5G.

Q: Are all three parts RoHS3 compliant and suitable for lead-free assembly?

A: Yes. The PBLS4005V,115, PBLS4005Y,115, and EMF5XV6T5G are all ROHS3 compliant and suitable for lead-free soldering processes. All three parts carry MSL 1 (Unlimited) moisture sensitivity ratings, indicating no special moisture control requirements during storage or handling.

Q: Why is the PBLS4005Y,115 recommended over the EMF5XV6T5G despite both being substitutes?

A: The PBLS4005Y,115 maintains complete electrical equivalence with the original PBLS4005V,115, including identical PNP collector-emitter breakdown voltage (40V), transition frequency (300MHz), and saturation voltage characteristics. The PBLS4005Y,115 carries active product status, ensuring long-term availability. The EMF5XV6T5G reduces the PNP breakdown voltage to 12V and does not specify transition frequency, making it suitable only for applications where these reduced specifications are acceptable. The PBLS4005Y,115 is the preferred choice for direct replacement in existing designs.

Q: What package considerations apply when substituting these parts?

A: The original PBLS4005V,115 uses SOT-666 packaging. The PBLS4005Y,115 uses 6-TSSOP packaging, and the EMF5XV6T5G uses SOT-563 packaging. Each package has a different physical footprint and pin layout. PCB design files must be updated to accommodate the selected substitute package. Pin-to-pin electrical function remains consistent across all three parts (1 NPN pre-biased, 1 PNP configuration with 47kOhm internal resistors), but physical placement and soldering patterns differ.

Q: Can the EMF5XV6T5G be used in applications where the original part operates the PNP transistor above 12V?

A: No. The EMF5XV6T5G specifies a maximum PNP collector-emitter breakdown voltage of 12V. Using this part in applications requiring PNP operation above 12V violates the component's electrical ratings and risks junction breakdown. The PBLS4005Y,115 must be used for applications requiring PNP operation at voltages between 12V and 40V.
