Engineering Selection Recommendations

ECH8654-TL-H as Primary Substitute:

The ECH8654-TL-H is the recommended substitute for the obsolete ECH8675-TL-H. Both components are manufactured by onsemi and share identical mechanical packaging, electrical voltage ratings, and thermal specifications.

The ECH8654-TL-H provides superior electrical performance across multiple parameters: continuous drain current is increased to 5A (versus 4.5A), and on-resistance is reduced to 38mOhm (versus 46mOhm). These improvements ensure the substitute component can handle equivalent or higher current loads with reduced power dissipation.

The ECH8654-TL-H is classified as an active product with current manufacturing status and full availability. This ensures long-term supply chain continuity and eliminates obsolescence risk associated with the ECH8675-TL-H.

Both components maintain identical compliance certifications: REACH Unaffected status, EAR99 export classification, and MSL Level 1 moisture sensitivity rating. The ECH8654-TL-H additionally carries RoHS3 compliance certification.

Gate charge and input capacitance parameters of the ECH8654-TL-H are slightly elevated (11nC and 960pF respectively, compared to 7.3nC and 670pF), but remain within acceptable ranges for logic level gate-driven applications and do not impose additional circuit design constraints.

Frequently Asked Questions (FAQ)

Q: Can the ECH8654-TL-H directly replace the ECH8675-TL-H in existing designs?

A: Yes. Both components share identical package geometry (8-SMD, Flat Lead), pinout configuration (2 P-Channel dual MOSFET array), voltage ratings (20V Vdss), and thermal specifications (150°C TJ). The ECH8654-TL-H provides equal or superior electrical performance and requires no circuit modifications.

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

A: The ECH8654-TL-H offers improved continuous drain current (5A versus 4.5A) and lower on-resistance (38mOhm versus 46mOhm). Gate charge and input capacitance are slightly higher but remain within acceptable operating ranges. The ECH8654-TL-H is an active product, while the ECH8675-TL-H is obsolete.

Q: Are there any compatibility concerns with packaging or mounting?

A: No. Both components use identical surface mount packaging: 8-SMD with flat leads in the 8-ECH supplier device package. PCB footprints, reflow soldering profiles, and handling procedures are identical.

Q: Does the ECH8654-TL-H meet the same compliance requirements?

A: Yes. Both components are REACH Unaffected and carry EAR99 export classification. The ECH8654-TL-H additionally carries RoHS3 compliance certification. Moisture sensitivity level is identical at MSL Level 1 (Unlimited).

Q: Will the higher gate charge of the ECH8654-TL-H affect circuit performance?

A: The gate charge increase from 7.3nC to 11nC is within acceptable tolerances for logic level gate-driven applications. This parameter affects gate drive timing and power dissipation in the gate driver circuit but does not require design changes for standard switching applications.

Q: Is the ECH8654-TL-H available in the same packaging format?

A: The ECH8654-TL-H is supplied in Tape & Reel (TR) packaging, while the ECH8675-TL-H packaging format is not specified. Both use identical component packaging (8-SMD, Flat Lead). Tape & Reel format is standard for high-volume surface mount assembly and is compatible with automated pick-and-place equipment.
