Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELL-ATV820M is determined by the following critical parameters:

• Inductance Value: Must be 82 µH (±20% tolerance acceptable)
• Current Rating: Minimum 1.1 A required; higher ratings acceptable
• DC Resistance: Target range 149–150 mOhm; minor variance acceptable
• Core Type & Shielding: Ferrite core with shielding required
• Mounting Configuration: Surface mount, nonstandard package
• Physical Footprint: 10.00mm x 10.00mm base dimensions; height variance within assembly constraints acceptable
• Compliance: ROHS3 compliance required

The SRU1048-820Y from Bourns Inc. meets all substitution criteria within these parameters.

Parameter Comparison

Engineering Selection Recommendations

The SRU1048-820Y is a direct functional equivalent for the ELL-ATV820M based on the following criteria:

• Electrical Equivalence: Identical inductance value (82 µH) and DC resistance (149–150 mOhm range) ensure equivalent circuit performance.
• Current Capacity: The 1.3 A rating of the SRU1048-820Y exceeds the 1.1 A requirement, providing operational margin.
• Physical Compatibility: Matching 10.00mm x 10.00mm footprint with 0.60mm height variance is acceptable for most PCB layouts.
• Compliance Status: Both components meet ROHS3 requirements; the substitute is actively manufactured and available.
• Availability: The SRU1048-820Y is in active production with 3600 units in stock, ensuring procurement continuity.

Selection of the SRU1048-820Y eliminates obsolescence risk while maintaining electrical and mechanical compatibility with the original design.

Frequently Asked Questions (FAQ)

Q: Can the SRU1048-820Y be used as a direct replacement for the ELL-ATV820M?

A: Yes. Both components share identical inductance (82 µH), matching DC resistance (149–150 mOhm), ferrite core construction, shielding, and 10.00mm x 10.00mm footprint. The SRU1048-820Y's higher current rating (1.3 A vs. 1.1 A) and active product status make it a suitable substitute.

Q: What is the significance of the height difference (4.50mm vs. 5.10mm)?

A: The 0.60mm height variance is typically acceptable in surface mount assembly. Verify clearance in your specific PCB layout, particularly if components are densely packed or if height-constrained applications are involved.

Q: Does the wider tolerance of the SRU1048-820Y (±30% vs. ±20%) affect circuit performance?

A: The ±30% tolerance of the SRU1048-820Y is wider but remains within acceptable ranges for most inductor applications. If your circuit requires tighter inductance tolerance, verify the specific design requirements before substitution.

Q: Are there packaging differences between these parts?

A: The ELL-ATV820M uses nonstandard packaging, while the SRU1048-820Y is supplied in Tape & Reel (TR) format. This affects procurement and handling but does not impact electrical or mechanical compatibility on the PCB.

Q: Is the SRU1048-820Y RoHS compliant?

A: Yes. The SRU1048-820Y is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.
