ECH8651R-TL-H MOSFET Equivalent & Substitute Parts

Part Overview

The ECH8651R-TL-H is an active, production-status dual N-channel MOSFET array manufactured by onsemi, designed for surface mount applications requiring 24V drain-to-source voltage capability and 10A continuous drain current. This component operates at logic level gate drive and is ROHS3 compliant with unlimited moisture sensitivity rating.

Substitute parts are identified when equivalent electrical performance parameters are maintained across the critical specifications: drain-to-source voltage (Vdss), continuous drain current (Id), maximum power dissipation, operating temperature range, and gate drive compatibility. Alternative packaging configurations may be selected based on application layout and assembly process requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ECH8651R-TL-H is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Drain-to-source voltage (Vdss) must equal or exceed 24V
• Continuous drain current (Id) must equal or exceed 10A at 25°C
• Maximum power dissipation must equal or exceed 1.5W
• Operating temperature range must support 150°C junction temperature
• Configuration must be dual N-channel with logic level gate drive capability

Mechanical & Compliance Criteria:

• Surface mount technology required
• ROHS3 compliance mandatory
• Moisture sensitivity level MSL 1 or better
• REACH unaffected status required

The ECH8697R-TL-W qualifies as a direct substitute based on full parameter equivalence across all electrical specifications and compliance certifications. The primary distinction is packaging configuration: ECH8651R-TL-H uses 8-ECH cut tape format, while ECH8697R-TL-W uses SOT-28FL/ECH8 tape and reel format.

Parameter Comparison

Engineering Selection Recommendations

Both the ECH8651R-TL-H and ECH8697R-TL-W are active production components manufactured by onsemi with identical ROHS3 compliance and REACH unaffected status. Selection between these parts is determined by packaging and supply chain requirements rather than electrical performance.

ECH8651R-TL-H (Primary Part):

• Supplied in cut tape (CT) and Digi-Reel® format
• Current inventory: 176,300 pieces
• Suitable for applications requiring standard tape packaging

ECH8697R-TL-W (Substitute Part):

• Supplied in tape and reel (TR) format with SOT-28FL/ECH8 package designation
• Current inventory: 62,300 pieces
• Suitable for high-volume automated assembly processes
• Offers improved electrical performance: lower Rds On (11.6 mOhm vs. 14 mOhm) and lower gate charge (6 nC vs. 24 nC)

Both parts maintain identical voltage, current, power, and temperature specifications. The ECH8697R-TL-W demonstrates superior switching characteristics due to reduced gate charge and on-resistance, making it the preferred selection when tape and reel packaging is compatible with assembly equipment.

Frequently Asked Questions (FAQ)

Q: Can ECH8697R-TL-W be used as a direct replacement for ECH8651R-TL-H?

A: Yes. Both parts are manufactured by onsemi with identical electrical specifications: 24V Vdss, 10A continuous drain current, 1.5W maximum power, and 150°C operating temperature. The primary difference is packaging format (cut tape vs. tape and reel). Pinout and electrical performance are equivalent.

Q: What is the difference between 8-ECH and SOT-28FL/ECH8 packaging?

A: Both are 8-SMD flat lead surface mount packages with identical physical dimensions and pinout. The designation difference reflects supplier packaging format: 8-ECH indicates cut tape and Digi-Reel® supply, while SOT-28FL/ECH8 indicates standard tape and reel format. The actual component package is identical.

Q: Why does ECH8697R-TL-W have lower gate charge (6 nC vs. 24 nC)?

A: Gate charge is measured at different gate-source voltage levels: ECH8651R-TL-H at 10V versus ECH8697R-TL-W at 4.5V. The lower measurement voltage for the substitute part results in lower reported gate charge. Both parts are logic level gate devices suitable for standard gate drive circuits.

Q: Are there any thermal or reliability differences between these parts?

A: No. Both parts specify identical maximum junction temperature (150°C), moisture sensitivity level (MSL 1 - Unlimited), and RoHS3 compliance. Thermal and reliability characteristics are equivalent.

Q: Which part should be selected for new designs?

A: Selection depends on assembly process requirements. For high-volume automated assembly with tape and reel equipment, ECH8697R-TL-W is appropriate. For applications using cut tape or Digi-Reel® format, ECH8651R-TL-H is suitable. Electrical performance is equivalent; packaging format is the determining factor.

Q: Is there a lead time or availability advantage to selecting one part over the other?

A: Current inventory shows ECH8651R-TL-H at 176,300 pieces and ECH8697R-TL-W at 62,300 pieces. Availability should be confirmed with the supplier for specific delivery requirements, as inventory levels change based on demand and production schedules.
