Substitute Part Grouping Explanation

Substitution of the BSP149 E6327 is determined by strict electrical and mechanical parameter matching within the SIPMOS® N-Channel MOSFET family. The following parameters establish substitution eligibility:

Critical Matching Parameters:

• Drain-to-Source Voltage (Vdss): 200V
• Continuous Drain Current (Id): 660mA @ 25°C
• On-State Resistance (Rds On): 1.8Ohm @ 660mA, 10V
• Gate Threshold Voltage (Vgs(th)): 1V @ 400µA
• Gate Charge (Qg): 14nC @ 5V
• Input Capacitance (Ciss): 430pF @ 25V
• Power Dissipation: 1.8W
• Operating Temperature Range: -55°C to 150°C
• Package: PG-SOT223-4 (TO-261-4, TO-261AA)
• FET Feature: Depletion Mode

All identified substitute parts maintain identical electrical specifications and package configuration, ensuring direct functional equivalence in circuit applications.

Engineering Selection Recommendations

BSP149H6327XTSA1 is the primary recommended substitute for the obsolete BSP149 E6327. This part maintains complete electrical and mechanical equivalence while offering the following advantages:

• Active product status ensures long-term availability and manufacturing support
• ROHS3 compliance satisfies current environmental and regulatory requirements
• Identical electrical specifications enable direct pin-for-pin replacement
• Available in Cut Tape and Digi-Reel® packaging for production flexibility
• Current inventory of 7300 units supports immediate procurement

BSP149H6906XTSA1 is an alternative substitute that provides identical electrical performance and package configuration. However, this part is classified as obsolete, limiting its suitability for new designs or long-term production requirements. It may be considered only when BSP149H6327XTSA1 availability is constrained.

Both substitute parts are manufactured by Infineon Technologies and belong to the SIPMOS® family, ensuring consistency with the original design intent and performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can BSP149H6327XTSA1 be used as a direct replacement for BSP149 E6327?

A: Yes. BSP149H6327XTSA1 is a parametric equivalent with identical electrical specifications (Vdss, Id, Rds On, Vgs(th), Qg, Ciss, power dissipation, and operating temperature range) and the same PG-SOT223-4 package configuration. Pin-for-pin substitution is supported without circuit modification.

Q: What is the difference between BSP149H6327XTSA1 and BSP149H6906XTSA1?

A: Both parts are parametric equivalents with identical electrical and mechanical specifications. The primary difference is product status: BSP149H6327XTSA1 is active with higher inventory availability (7300 units), while BSP149H6906XTSA1 is obsolete with lower inventory (2100 units). For new designs, BSP149H6327XTSA1 is preferred.

Q: Does the packaging format affect substitution compatibility?

A: No. Both substitute parts are available in Cut Tape (CT) and Digi-Reel® packaging formats, which are standard production packaging options. The underlying component specifications and PG-SOT223-4 package remain unchanged. Packaging format selection depends on production assembly requirements, not electrical compatibility.

Q: Why is RoHS compliance important for this substitution?

A: The original BSP149 E6327 is RoHS non-compliant, while both substitute parts (BSP149H6327XTSA1 and BSP149H6906XTSA1) are ROHS3 compliant. For applications subject to environmental regulations or customer requirements, ROHS3-compliant substitutes ensure regulatory adherence without affecting electrical performance.

Q: Are there any thermal or performance differences between the main part and substitutes?

A: No. All three parts share identical thermal characteristics, including maximum power dissipation (1.8W) and operating temperature range (-55°C to 150°C). Thermal performance in circuit applications will be equivalent.

Q: What is the recommended substitute if BSP149H6327XTSA1 becomes unavailable?

A: BSP149H6906XTSA1 provides complete electrical and mechanical equivalence as a secondary option. However, due to its obsolete status, long-term availability cannot be guaranteed. For critical applications, BSP149H6327XTSA1 should be prioritized due to its active product status.
