Substitute Part Grouping Explanation

Substitution of the PBLS4004V,115 is determined by strict equivalence across the following electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Identical transistor configuration: 1 NPN pre-biased and 1 PNP transistor
• Matching maximum collector currents: 100mA (NPN) and 500mA (PNP)
• Matching collector-emitter breakdown voltages: 50V (NPN) and 40V (PNP)
• Identical integrated base and emitter-base resistor values: 22kOhms each
• Matching DC current gain specifications at specified test conditions
• Identical transition frequency: 300MHz
• Matching maximum power dissipation: 300mW
• Matching collector cutoff current: 1µA maximum

Mechanical Equivalence Criteria:

• Surface mount mounting type
• Compatible package footprint and pin configuration
• Matching moisture sensitivity level: MSL 1

Compliance Equivalence Criteria:

• RoHS3 compliance maintained
• REACH unaffected status maintained

Substitute parts must satisfy all listed criteria to ensure functional and physical compatibility without circuit redesign or board layout modification.

Parameter Comparison

Engineering Selection Recommendations

The PBLS4004Y,115 is the manufacturer-recommended substitute for the obsolete PBLS4004V,115. Both components are manufactured by NXP and share identical electrical specifications, integrated resistor values, and performance characteristics across all critical parameters.

Key Considerations:

The primary difference between these components is the package type: PBLS4004V,115 uses SOT-666 packaging, while PBLS4004Y,115 uses SOT-363 packaging. This package difference requires PCB layout modification and component footprint redesign. Pin configuration and electrical function remain equivalent.

The PBLS4004Y,115 carries active product status, ensuring ongoing availability and manufacturing support. The PBLS4004V,115 is obsolete, making the substitute the appropriate choice for new production and long-term supply chain continuity.

Both components maintain identical RoHS3 compliance and REACH unaffected status, satisfying regulatory requirements without modification.

Frequently Asked Questions (FAQ)

Q: Can PBLS4004Y,115 be used as a direct replacement for PBLS4004V,115 without circuit modification?

A: The electrical specifications are identical, but the package type differs (SOT-363 versus SOT-666). Direct PCB substitution without layout modification is not possible. Circuit function remains unchanged; only the physical footprint requires redesign.

Q: Are the integrated resistor values identical between these parts?

A: Yes. Both components contain identical base resistor (R1) and emitter-base resistor (R2) values of 22kOhms each. No external biasing network adjustment is required.

Q: Do both parts meet the same compliance standards?

A: Yes. Both PBLS4004V,115 and PBLS4004Y,115 are RoHS3 compliant and REACH unaffected. Regulatory requirements are satisfied by either component.

Q: What is the significance of the product status difference?

A: PBLS4004V,115 is obsolete, indicating discontinued manufacturing and limited availability. PBLS4004Y,115 is active, ensuring reliable supply, ongoing manufacturing support, and long-term component availability for production and maintenance applications.

Q: Are the electrical performance characteristics identical?

A: Yes. Maximum collector currents, breakdown voltages, DC current gain, transition frequency, power dissipation, and saturation characteristics are identical across both components. Performance in circuit operation is equivalent.

Q: What packaging considerations apply to substitution?

A: PBLS4004V,115 uses SOT-666 (6-pin) packaging, while PBLS4004Y,115 uses SOT-363 (6-pin) packaging. Although both are 6-pin packages, the physical dimensions and pin spacing differ. PCB footprint modification is required for component substitution.
