VEC2315-TL-H Equivalent & Substitute Parts

Part Overview

The VEC2315-TL-H is a dual P-channel MOSFET array manufactured by onsemi, rated for 60V drain-to-source voltage with 2.5A continuous drain current at 25°C. This component is packaged in an 8-SMD flat lead SOT-28FL/VEC8 surface mount configuration and is designed for logic-level gate switching applications.

The VEC2315-TL-H has been discontinued at DiGi Electronics. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for applications utilizing this MOSFET array.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the VEC2315-TL-H must satisfy the following electrical and mechanical criteria:

Electrical Parameters (Required Match or Exceed):

• Drain to Source Voltage (Vdss): 60V minimum
• Configuration: 2 P-Channel (Dual) MOSFET array
• Continuous Drain Current (Id): Must support 2.5A or greater at 25°C
• Operating Temperature: 150°C (TJ) or higher
• On-state Resistance (Rds On): Lower or equivalent values preferred for thermal performance

Mechanical Parameters (Required Match):

• Mounting Type: Surface Mount
• Package Configuration: 8-SMD, Flat Lead format
• Pin count and footprint compatibility with SOT-28FL/VEC8 or equivalent TSMT8 package

Compliance Parameters (Required Match):

• RoHS3 Compliance
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

The QH8JC5TCR from Rohm Semiconductor meets all substitution criteria. This part exceeds the continuous drain current specification (3.5A versus 2.5A), maintains the 60V Vdss rating, and is packaged in a compatible 8-SMD flat lead surface mount configuration (TSMT8). Both parts are RoHS3 compliant with MSL-1 moisture sensitivity ratings.

Parameter Comparison

Engineering Selection Recommendations

The QH8JC5TCR is the qualified substitute for the VEC2315-TL-H based on the following engineering criteria:

Electrical Compatibility: The QH8JC5TCR meets or exceeds all critical electrical specifications. The 60V Vdss rating is identical, and the 3.5A continuous drain current exceeds the original 2.5A specification, providing additional design margin. The on-state resistance of 91 mOhm at 3.5A, 10V is lower than the VEC2315-TL-H specification of 137 mOhm at 1.5A, 10V, resulting in improved thermal performance and reduced power dissipation.

Mechanical Compatibility: Both parts utilize 8-SMD flat lead surface mount packaging. The TSMT8 package used by the QH8JC5TCR is mechanically and electrically compatible with the SOT-28FL/VEC8 package of the original part, supporting direct footprint substitution on existing printed circuit boards.

Compliance and Availability: The QH8JC5TCR is RoHS3 compliant and carries MSL-1 moisture sensitivity rating, matching the original part's environmental compliance profile. The substitute part is currently in active production status with 9,066 units in stock, ensuring supply chain continuity compared to the discontinued VEC2315-TL-H.

Product Status: The discontinuation of the VEC2315-TL-H at DiGi Electronics necessitates transition to an active alternative. The QH8JC5TCR from Rohm Semiconductor provides a direct functional replacement with enhanced electrical performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can the QH8JC5TCR be used as a direct replacement for the VEC2315-TL-H in existing designs?

A: Yes. Both parts are dual P-channel MOSFET arrays with identical 60V Vdss ratings, compatible 8-SMD flat lead surface mount packaging, and matching operating temperature ranges. The QH8JC5TCR exceeds the continuous drain current specification and provides lower on-state resistance, making it functionally superior for the same application space.

Q: What are the key differences between the VEC2315-TL-H and QH8JC5TCR?

A: The primary differences are continuous drain current (3.5A versus 2.5A), on-state resistance (91 mOhm versus 137 mOhm), gate charge (17.3 nC versus 11 nC), and input capacitance (850 pF versus 420 pF). The QH8JC5TCR also features a slightly higher maximum power rating (1.1W versus 1W). These differences represent performance enhancements rather than incompatibilities.

Q: Are the package footprints identical between SOT-28FL/VEC8 and TSMT8?

A: Both packages are 8-SMD flat lead surface mount configurations with compatible pin layouts and footprints. The TSMT8 designation used by Rohm Semiconductor is mechanically equivalent to the SOT-28FL/VEC8 package, supporting direct PCB substitution without layout modifications.

Q: What compliance certifications apply to the QH8JC5TCR?

A: The QH8JC5TCR is RoHS3 compliant and carries MSL-1 (Unlimited) moisture sensitivity level rating, matching the environmental and regulatory compliance profile of the original VEC2315-TL-H.

Q: Why is the gate charge specification higher for the QH8JC5TCR?

A: The QH8JC5TCR exhibits higher gate charge (17.3 nC versus 11 nC) due to its enhanced current-handling capability (3.5A versus 2.5A). Higher gate charge is a characteristic trade-off associated with increased current capacity in MOSFET array designs. This parameter does not prevent substitution and is typical for higher-rated alternatives.

Q: Is the QH8JC5TCR available in the same packaging format as the original part?

A: Yes. The QH8JC5TCR is supplied in Tape & Reel (TR) format in the TSMT8 package, which is mechanically and electrically compatible with the SOT-28FL/VEC8 package of the VEC2315-TL-H. Both are 8-SMD flat lead surface mount configurations suitable for automated assembly processes.
