Engineering Selection Recommendations

B82462G4103M000 (EPCOS - TDK Electronics)

This substitute provides superior electrical performance with 1.5 A current rating and 62 mOhm maximum DC resistance, representing a 35% reduction in resistance compared to the main part. The component carries AEC-Q200 automotive qualification and operates across -55°C to 150°C, extending the thermal operating range. Product status is active with established supply availability. Footprint dimensions are comparable (6.30mm x 6.30mm vs. 6.40mm x 6.00mm), with a maximum seated height of 3.00mm. ROHS3 compliance and MSL 1 rating match the original specification.

SRR5028-100Y (Bourns Inc.)

This substitute delivers 1.5 A current rating and 70 mOhm maximum DC resistance, providing a 26% reduction in resistance. The component features a smaller footprint (5.80mm x 5.80mm) with identical maximum seated height of 3.00mm. Operating temperature range is -40°C to 125°C. Product status is active with established supply. Inductance tolerance is ±30%, which is wider than the main part's ±20%. ROHS3 compliance and MSL 1 rating are maintained. Additional performance data includes Q factor of 9 at 2.52 MHz and self-resonant frequency of 30 MHz.

Both substitutes are ROHS3 compliant, carry MSL 1 rating, and are actively manufactured, ensuring long-term availability and regulatory compliance for new designs and production continuity.

Frequently Asked Questions (FAQ)

Q: Can B82462G4103M000 or SRR5028-100Y be used as direct replacements for ELL-6RH100M?

A: Both parts meet the core electrical requirements: 10 µH inductance, shielded configuration, surface mount mounting, and current ratings exceeding 1.1 A. DC resistance values are lower than the original specification. Physical footprints differ slightly; verify PCB layout compatibility before implementation. Both are ROHS3 compliant with MSL 1 rating.

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

A: B82462G4103M000 offers tighter inductance tolerance (±20% vs. ±30%), lower DC resistance (62 mOhm vs. 70 mOhm), wider operating temperature range (-55°C to 150°C vs. -40°C to 125°C), and AEC-Q200 qualification. SRR5028-100Y features a smaller footprint (5.80mm x 5.80mm vs. 6.30mm x 6.30mm) and provides additional frequency performance data (Q factor and self-resonant frequency).

Q: Are there any package or footprint considerations?

A: All three parts use nonstandard surface mount packages. The main part measures 6.40mm x 6.00mm with 2.80mm maximum height. B82462G4103M000 measures 6.30mm x 6.30mm with 3.00mm height. SRR5028-100Y measures 5.80mm x 5.80mm with 3.00mm height. Verify PCB pad layout and clearance requirements before substitution.

Q: Why is the main part classified as obsolete?

A: ELL-6RH100M carries obsolete product status. Both substitute parts are actively manufactured and supported, providing supply chain continuity and access to current manufacturing processes and quality standards.

Q: Do the substitute parts maintain regulatory compliance?

A: Both B82462G4103M000 and SRR5028-100Y are ROHS3 compliant with MSL 1 (Unlimited) rating, matching the original part's compliance profile. B82462G4103M000 additionally carries AEC-Q200 automotive qualification.
