Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PBLS4005Y,115 is determined by the following critical parameters:

Primary Substitution Criteria:

• Transistor configuration: 1 NPN and 1 PNP pre-biased dual transistor
• Package compatibility: 6-TSSOP, SC-88, or SOT-363 surface mount packages
• Collector current rating: Minimum 100mA for NPN, 500mA for PNP
• Collector-emitter breakdown voltage: Minimum 50V for NPN, 40V for PNP
• Base bias resistor values: 47kOhms for both R1 and R2
• Transition frequency: Minimum 300MHz
• Power dissipation: Minimum 300mW
• Compliance: ROHS3 compliant, MSL 1

Substitute Parts Identified:

1. DCX123JU-7-F (Diodes Incorporated): Meets primary substitution criteria with equivalent NPN/PNP configuration, 50V breakdown voltage, 100mA collector current, and SOT-363 package compatibility. Transition frequency of 250MHz is below the main part specification.

2. EMF5XV6T5G (onsemi): Meets primary substitution criteria with equivalent NPN/PNP configuration, 50V NPN breakdown voltage, 100mA NPN and 500mA PNP collector current ratings, and SOT-563 package. Product status is obsolete. Transition frequency specification not provided.

Parameter Comparison

Engineering Selection Recommendations

DCX123JU-7-F (Diodes Incorporated): This part is suitable for direct substitution in applications where the transition frequency requirement can be met at 250MHz instead of 300MHz, and where the NPN collector current of 100mA is sufficient. The base resistor R1 differs at 2.2kOhms versus 47kOhms on the main part, which affects bias characteristics. Package compatibility is confirmed across 6-TSSOP, SC-88, and SOT-363 options. The part is in active production with high inventory availability (188100 units). ROHS3 compliance and MSL 1 rating match the main part specifications.

EMF5XV6T5G (onsemi): This part is not recommended for new designs due to obsolete product status. While electrical parameters align closely with the main part (50V NPN breakdown, 100mA NPN and 500mA PNP collector current, 47kOhms base resistors), the transition frequency is not specified and the part is no longer in active production. Package options differ (SOT-563, SOT-666 versus 6-TSSOP/SOT-363), requiring PCB layout modifications. ROHS3 compliance and MSL 1 rating are maintained.

Frequently Asked Questions (FAQ)

Q: Can DCX123JU-7-F replace PBLS4005Y,115 in all applications?

A: DCX123JU-7-F is electrically compatible for most applications but has two key differences: transition frequency is 250MHz versus 300MHz on the main part, and the base resistor R1 is 2.2kOhms instead of 47kOhms. Applications operating above 250MHz or requiring specific bias characteristics tied to the 47kOhms base resistor value require evaluation.

Q: What is the package compatibility between these parts?

A: PBLS4005Y,115 and DCX123JU-7-F both support 6-TSSOP, SC-88, and SOT-363 packages, enabling direct PCB footprint compatibility. EMF5XV6T5G uses SOT-563 and SOT-666 packages, which require different PCB layouts.

Q: Why is EMF5XV6T5G listed as a substitute if it is obsolete?

A: EMF5XV6T5G is documented as a historical substitute based on electrical parameter alignment. Obsolete status indicates the part is no longer manufactured and should not be selected for new designs. Existing inventory may be available through secondary sources, but long-term supply cannot be assured.

Q: How do the base resistor differences affect circuit operation?

A: The base resistor R1 determines the bias current and switching characteristics of the pre-biased transistor. DCX123JU-7-F uses 2.2kOhms (lower impedance, higher bias current) versus 47kOhms on PBLS4005Y,115 (higher impedance, lower bias current). This affects saturation voltage, switching speed, and power consumption. Circuit-level evaluation is required if bias point specifications are critical.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. PBLS4005Y,115, DCX123JU-7-F, and EMF5XV6T5G are all ROHS3 compliant with MSL 1 (unlimited moisture sensitivity level), meeting environmental and regulatory requirements for commercial and industrial applications.

Q: What is the primary reason to select a substitute part?

A: Substitute selection is driven by inventory availability, supply chain continuity, or sourcing cost optimization. DCX123JU-7-F offers significantly higher inventory (188100 units versus 3657 units for the main part). EMF5XV6T5G should be avoided for new designs due to obsolete status, though it may be considered only if existing stock is available and application requirements align with its specifications.
