ECH8653-TL-H MOSFET Equivalent & Substitute Parts

Part Overview

The ECH8653-TL-H is a dual N-channel MOSFET array manufactured by onsemi, rated for 20V drain-to-source voltage and 7.5A continuous drain current. This component is classified as obsolete, necessitating identification of active equivalent parts for new designs and ongoing production requirements. The part features logic level gate drive capability and is packaged in an 8-SMD flat lead surface mount configuration with 1.5W maximum power dissipation.

Due to its obsolete status, sourcing alternatives with compatible electrical and mechanical characteristics is essential for design continuity and supply chain management.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ECH8653-TL-H is determined by the following critical parameters:

Electrical Compatibility Criteria:

• Configuration: Dual N-channel MOSFET array
• Drain-to-source voltage rating must equal or exceed 20V
• Continuous drain current must equal or exceed 7.5A
• On-state resistance (Rds On) must not exceed 20mOhm at specified gate-source voltage
• Gate charge and input capacitance characteristics must support equivalent switching performance
• Maximum power dissipation of 1.5W must be maintained

Mechanical Compatibility Criteria:

• Surface mount packaging with 8-SMD flat lead configuration
• Logic level gate drive capability
• Operating temperature range to 150°C (TJ)
• Moisture sensitivity level MSL 1 (Unlimited)

Regulatory and Compliance Criteria:

• REACH compliance status
• RoHS compliance status where applicable

The ECH8697R-TL-W qualifies as a substitute based on superior electrical ratings (24V Vdss, 10A Id) that encompass the original part's requirements, maintained surface mount packaging, logic level gate drive with 2.5V drive capability, and active product status with full regulatory compliance.

Engineering Selection Recommendations

ECH8697R-TL-W as Primary Substitute:

The ECH8697R-TL-W is the qualified substitute for the obsolete ECH8653-TL-H based on the following engineering criteria:

1. Electrical Performance: The ECH8697R-TL-W provides superior voltage and current ratings (24V/10A versus 20V/7.5A), ensuring full compatibility with applications designed for the original part. The lower on-state resistance (11.6mOhm versus 20mOhm) and reduced gate charge (6nC versus 18.5nC) deliver improved switching efficiency and reduced power dissipation.

2. Package Compatibility: Both parts utilize identical 8-SMD flat lead surface mount packaging, enabling direct board-level substitution without layout modifications.

3. Regulatory Compliance: The ECH8697R-TL-W maintains REACH compliance and achieves RoHS3 compliance, meeting current regulatory requirements. The original ECH8653-TL-H carries REACH Unaffected status.

4. Product Status: The ECH8697R-TL-W is active in production with 62,300 pieces in stock, providing supply continuity and long-term availability compared to the obsolete ECH8653-TL-H.

5. Functional Equivalence: Both parts feature dual N-channel configuration with logic level gate drive, maintaining functional equivalence in circuit applications.

Frequently Asked Questions (FAQ)

Q: Can the ECH8697R-TL-W directly replace the ECH8653-TL-H on existing PCBs?

A: Yes. Both parts share identical 8-SMD flat lead surface mount packaging and pinout configuration. Direct substitution is possible without PCB layout modifications.

Q: What are the key electrical differences between these parts?

A: The ECH8697R-TL-W provides higher voltage rating (24V versus 20V), higher current rating (10A versus 7.5A), lower on-state resistance (11.6mOhm versus 20mOhm), and lower gate charge (6nC versus 18.5nC). These represent performance improvements that maintain backward compatibility.

Q: Is the ECH8697R-TL-W suitable for applications originally designed for the ECH8653-TL-H?

A: Yes. The superior electrical ratings of the ECH8697R-TL-W encompass all operating parameters of the original part, making it suitable for all applications within the original design envelope.

Q: What is the significance of the "Common Drain" configuration noted for the ECH8697R-TL-W?

A: The common drain configuration indicates the internal circuit topology of the dual N-channel array. This does not affect substitution compatibility and is a standard feature of dual MOSFET arrays in this package class.

Q: Are there any compliance differences between the two parts?

A: The ECH8697R-TL-W achieves RoHS3 compliance, while the ECH8653-TL-H is REACH Unaffected. Both parts maintain REACH compliance status. The ECH8697R-TL-W meets current regulatory requirements for new designs.

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

A: Both designations refer to the same 8-SMD flat lead surface mount package. The SOT-28FL/ECH8 is the supplier device package designation for the ECH8697R-TL-W, while 8-ECH is the designation for the ECH8653-TL-H. They are mechanically and electrically compatible.

Q: Why is the ECH8653-TL-H classified as obsolete?

A: Obsolete status indicates the part is no longer in active production. The ECH8697R-TL-W represents the active equivalent with superior performance characteristics and current regulatory compliance.
