Substitute Part Grouping Explanation

Substitution of the FDV304P-D87Z is determined by strict alignment of electrical and mechanical parameters within the P-Channel MOSFET category. The critical parameters governing substitution are:

Electrical Parameters:

Drain-to-Source Voltage (Vdss) must equal or exceed 25 V
Continuous Drain Current (Id) must equal or exceed 460 mA at 25°C
On-state resistance (Rds On) must not exceed 1.1 Ohm at specified conditions
Power dissipation capability must support 350 mW or greater
Operating temperature range must encompass -55°C to 150°C

Mechanical Parameters:

Package type must be SOT-23-3 (TO-236-3, SC-59) for direct board-level compatibility
Mounting type must be Surface Mount
Moisture Sensitivity Level must be 1 (Unlimited) or equivalent

Substitute parts are grouped into three categories:

Direct Equivalent (Parametric Match): FDV304P-F169 — Identical electrical specifications and package, different packaging format (Tape & Reel vs. Cut Tape)
Direct Successor (Active Status): FDV304P — Identical electrical specifications, active product status, improved availability
Similar Substitutes (Parameter Relaxation): BSH202,215 and BSH203,215 — Higher voltage rating (30 V), comparable or superior current handling, same package family, but with parameter variations in Rds On, gate charge, and input capacitance

Engineering Selection Recommendations

Primary Recommendation: FDV304P

The FDV304P is the preferred substitute for the FDV304P-D87Z. This part maintains identical electrical specifications (25 V, 460 mA, 1.1 Ohm Rds On, 350 mW) and package configuration (SOT-23-3). The FDV304P holds active product status, ensuring long-term availability and supply chain stability. It is ROHS3 compliant and carries the same REACH unaffected designation. Inventory availability is significantly higher (440,100 pieces) compared to the obsolete FDV304P-D87Z (932 pieces), supporting both immediate and sustained production requirements.

Secondary Recommendation: FDV304P-F169

The FDV304P-F169 provides parametric equivalence with identical electrical specifications and package type. However, this part is also classified as obsolete, limiting its suitability for new designs or long-term supply assurance. It is appropriate only for legacy system maintenance where the specific packaging format (Tape & Reel) is required and supply is confirmed available.

Tertiary Consideration: BSH202,215 and BSH203,215

The Nexperia BSH202,215 and BSH203,215 devices offer higher voltage ratings (30 V vs. 25 V) and comparable or superior current handling. Both parts are manufactured in the TO-236AB package, which is mechanically and electrically compatible with SOT-23-3 applications. However, both parts carry obsolete or restricted product status (Obsolete and Not For New Designs, respectively). The BSH202,215 exhibits lower on-state resistance (0.9 Ohm) but requires 10 V gate drive, whereas the BSH203,215 operates at 4.5 V gate drive with similar Rds On performance. These substitutes are suitable only when the higher voltage rating provides design margin and supply availability is confirmed.

Frequently Asked Questions (FAQ)

Q: Can FDV304P-F169 be used as a direct replacement for FDV304P-D87Z?

A: Yes, FDV304P-F169 is a parametric equivalent with identical electrical specifications and SOT-23-3 package. However, both parts are obsolete. The FDV304P is preferred due to active product status and superior availability.

Q: What is the difference between FDV304P and FDV304P-D87Z?

A: Both parts share identical electrical specifications (25 V, 460 mA, 1.1 Ohm Rds On, 350 mW) and package type (SOT-23-3). The primary difference is product status: FDV304P is active, while FDV304P-D87Z is obsolete. The suffix "-D87Z" indicates a specific packaging or distribution variant of the base FDV304P design.

Q: Can BSH202,215 or BSH203,215 replace FDV304P-D87Z?

A: BSH202,215 and BSH203,215 are mechanically compatible (TO-236AB package) and electrically capable substitutes with higher voltage ratings (30 V). However, both parts are obsolete or restricted from new designs. Substitution is acceptable only when the higher voltage rating provides design margin and supply is confirmed. Gate drive voltage requirements differ: BSH202,215 requires 10 V, while BSH203,215 operates at 4.5 V.

Q: Are there any package compatibility concerns when substituting these parts?

A: All substitute parts use SOT-23-3 or TO-236AB packages, which are mechanically and electrically equivalent in the TO-236-3, SC-59 family. Direct board-level substitution is supported without layout modification. Pin configuration and polarity are identical across all listed parts.

Q: What compliance certifications should I verify before selecting a substitute?

A: All listed substitute parts are ROHS3 compliant and carry REACH unaffected status, matching the regulatory requirements of the original FDV304P-D87Z. Verify ECCN classification (EAR99 for all listed parts) and HTSUS code (8541.21.0095) for export and procurement compliance.

Q: Why is FDV304P recommended over FDV304P-D87Z if they are electrically identical?

A: FDV304P is recommended because it maintains active product status, ensuring continued manufacturing, long-term availability, and supply chain support. The FDV304P-D87Z is obsolete, indicating discontinued production and limited remaining inventory. For new designs and sustained production, FDV304P provides superior lifecycle assurance.

Q: What are the gate drive voltage differences among these parts?

A: FDV304P-D87Z, FDV304P-F169, and FDV304P operate at -8 V maximum gate voltage. FDV304P (active variant) supports ±8 V. BSH202,215 supports ±20 V gate voltage with 10 V drive requirement. BSH203,215 supports ±8 V gate voltage with 4.5 V drive requirement. Verify gate drive circuit compatibility before substitution.

Q: How do on-state resistance specifications compare across these parts?

A: FDV304P-D87Z, FDV304P-F169, and FDV304P all specify 1.1 Ohm maximum Rds On at 500 mA, 4.5 V. BSH202,215 and BSH203,215 both specify 0.9 Ohm maximum Rds On, but at different test conditions (280 mA, 10 V and 280 mA, 4.5 V respectively). Lower Rds On values in Nexperia parts result in reduced power dissipation and improved thermal performance.
