Key Parameters

Substitute Part Grouping Explanation

Substitution of the DLW5ATH501TQ2L is determined by the following critical parameters:

Functional Requirements:

• 2-line common mode choke configuration
• Surface mount technology
• AEC-Q200 automotive qualification
• Operating temperature range: -40°C ~ 125°C
• ROHS3 compliance

Electrical Compatibility Criteria:

• Impedance at 100 MHz: minimum 500 Ohms (equal or higher acceptable for filtering applications)
• Current rating: minimum 1.5A (equal or higher acceptable)
• DC voltage rating: minimum 50V (equal or higher acceptable)
• DC resistance: lower values preferred for reduced power dissipation

Mechanical Compatibility Criteria:

• Surface mount package with 4-pad configuration
• Physical dimensions and height must accommodate existing PCB layouts

The substitute part ACM70V-701-2PL-TL00 meets these criteria with enhanced electrical performance characteristics while maintaining functional equivalence for the intended application.

Engineering Selection Recommendations

The ACM70V-701-2PL-TL00 serves as a functional substitute for the discontinued DLW5ATH501TQ2L based on the following engineering criteria:

Compliance & Certification: Both components maintain AEC-Q200 automotive qualification and ROHS3 compliance, ensuring regulatory requirements are met for automotive and industrial applications.

Electrical Performance: The substitute provides superior electrical characteristics: higher impedance (700 Ohms vs. 500 Ohms), increased current capacity (4A vs. 1.5A), higher voltage rating (80V vs. 50V), and significantly lower DC resistance (15mOhm vs. 56mOhm). These enhancements result in improved filtering performance and reduced power dissipation.

Physical Considerations: The substitute component is larger in footprint (7.00mm x 6.00mm vs. 5.00mm x 3.60mm) and height (4.60mm vs. 2.35mm). PCB layout verification is required to confirm accommodation of the increased dimensions. The package configuration changes from 4 PC Pad to 4 J-Lead, requiring footprint redesign.

Availability: The substitute is currently active in production with 21,707 pieces in stock, providing reliable long-term procurement availability compared to the discontinued main part.

Frequently Asked Questions (FAQ)

Q: Can the ACM70V-701-2PL-TL00 directly replace the DLW5ATH501TQ2L without circuit modifications?

A: The substitute meets all functional requirements for 2-line common mode choke filtering. However, PCB layout modifications are necessary due to increased component dimensions (7.00mm x 6.00mm footprint vs. 5.00mm x 3.60mm) and different pad configuration (4 J-Lead vs. 4 PC Pad). Electrical circuit operation remains compatible.

Q: What are the key differences in electrical performance?

A: The substitute provides higher impedance (700 Ohms vs. 500 Ohms at 100 MHz), greater current handling capacity (4A vs. 1.5A), higher voltage rating (80V vs. 50V), and lower DC resistance (15mOhm vs. 56mOhm). These characteristics enhance filtering effectiveness and reduce thermal dissipation.

Q: Are both components suitable for automotive applications?

A: Both the DLW5ATH501TQ2L and ACM70V-701-2PL-TL00 carry AEC-Q200 qualification, confirming suitability for automotive-grade applications. Both maintain ROHS3 compliance and unlimited moisture sensitivity level (MSL 1).

Q: What is the impact of the different package configurations?

A: The main part uses a 4 PC Pad horizontal package, while the substitute uses a 4 J-Lead horizontal package. This requires footprint redesign on the PCB. The J-Lead configuration may provide improved mechanical reliability in high-vibration environments typical of automotive applications.

Q: Is the substitute available for immediate procurement?

A: The ACM70V-701-2PL-TL00 is currently active in production status with 21,707 pieces in stock, providing immediate availability. The original DLW5ATH501TQ2L is discontinued at DiGi Electronics, making the substitute the recommended solution for new procurement.
