Electrical Compatibility Criteria:

• FET Type: P-Channel topology
• Drain to Source Voltage (Vdss): 60V minimum rating
• Continuous Drain Current (Id): 3A or greater at 25°C
• On-State Resistance (Rds On): 105mOhm or lower @ 3A, 10V
• Gate Threshold Voltage (Vgs(th)): 3V or lower @ 250µA
• Gate Charge (Qg): 24nC or lower @ 10V
• Maximum Gate Voltage (Vgs): ±20V or greater
• Input Capacitance (Ciss): 759pF or lower @ 30V
• Power Dissipation: 1.6W or greater
• Operating Temperature Range: -55°C to 150°C (TJ) or wider

Mechanical Compatibility Criteria:

• Mounting Type: Surface Mount
• Package / Case: SOT-23-6 Thin or equivalent pinout-compatible package
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Substitute parts must satisfy all electrical parameters at or above the specified values and maintain mechanical compatibility with the original package footprint.

Engineering Selection Recommendations

FDC5614P (Direct Equivalent - onsemi)

The FDC5614P is the active production equivalent of the obsolete FDC5614P_D87Z. Both parts are manufactured by onsemi and share identical electrical specifications: 60V Vdss, 3A continuous drain current, 105mOhm Rds On @ 3A/10V, and 1.6W power dissipation. The FDC5614P is ROHS3 compliant and currently in active production with substantial inventory availability (24,972 pcs). This part is the primary replacement for the FDC5614P_D87Z and requires no circuit redesign.

ZXMP6A17E6TA (Similar Substitute - Diodes Incorporated)

The ZXMP6A17E6TA is a functionally compatible P-Channel MOSFET manufactured by Diodes Incorporated. It maintains the 60V Vdss rating and -55°C to 150°C operating temperature range. However, this part operates at 2.3A continuous drain current (versus 3A for the main part) and exhibits 125mOhm Rds On @ 2.3A/10V (versus 105mOhm). The ZXMP6A17E6TA is qualified to AEC-Q101 automotive standards and ROHS3 compliant. This substitute is suitable for applications where the 2.3A current rating and higher on-state resistance are acceptable within circuit design margins. The SOT-23-6 package is mechanically compatible with the original footprint.

Frequently Asked Questions (FAQ)

Q: Can the FDC5614P directly replace the FDC5614P_D87Z without circuit modification?

A: Yes. The FDC5614P is the active production equivalent with identical electrical specifications. Both parts share the same Vdss (60V), Id (3A), Rds On (105mOhm @ 3A/10V), gate charge (24nC @ 10V), and power dissipation (1.6W). The FDC5614P is a direct pin-for-pin and functional replacement.

Q: What are the limitations of using ZXMP6A17E6TA as a substitute?

A: The ZXMP6A17E6TA operates at 2.3A continuous drain current, which is 23% lower than the FDC5614P_D87Z specification of 3A. Additionally, its Rds On is 125mOhm @ 2.3A/10V, compared to 105mOhm for the main part. These differences result in higher on-state voltage drop and reduced current handling capacity. This substitute is applicable only when circuit design margins accommodate the reduced current rating and increased resistance.

Q: Are the package footprints compatible between all three parts?

A: The FDC5614P and FDC5614P_D87Z both use SOT-23-6 Thin (TSOT-23-6) packaging. The ZXMP6A17E6TA uses SOT-23-6 packaging. Both package designations are mechanically compatible and share the same pinout footprint for surface mount PCB assembly.

Q: What compliance certifications apply to each substitute?

A: The FDC5614P is ROHS3 compliant and REACH unaffected. The ZXMP6A17E6TA is ROHS3 compliant, REACH unaffected, and additionally qualified to AEC-Q101 automotive standards. Both parts maintain MSL 1 (Unlimited) moisture sensitivity rating.

Q: Which substitute should be selected for new designs?

A: The FDC5614P is the recommended selection for new designs. It is the active production equivalent with identical electrical performance, established supply chain availability, and no design trade-offs. The ZXMP6A17E6TA should be selected only when automotive qualification (AEC-Q101) is a design requirement and the reduced current rating is acceptable.

Q: Are there inventory considerations between the substitute options?

A: The FDC5614P has 24,972 pcs in stock. The ZXMP6A17E6TA has 95,200 pcs in stock. Both parts are available in Cut Tape (CT) and Digi-Reel® packaging formats. The ZXMP6A17E6TA offers higher inventory depth, though the FDC5614P inventory is substantial for most production requirements.
