ELL-ATP471MB Equivalent & Substitute Parts

Part Overview

The ELL-ATP471MB is a 470 µH shielded wirewound inductor manufactured by Panasonic Electronic Components, rated for 500 mA continuous current with 780mOhm DC resistance. This component is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. The part features surface mount technology with nonstandard corner terminals and is RoHS3 compliant with MSL Level 1 rating.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the ELL-ATP471MB is determined by strict equivalence across the following critical parameters:

• Inductance value: 470 µH at 100 kHz test frequency
• Inductance tolerance: ±20%
• Current rating: 500 mA minimum
• Shielding requirement: Shielded construction
• Mounting technology: Surface mount
• RoHS3 compliance and MSL Level 1 rating

The B82464G4474M000 qualifies as a direct substitute based on matching inductance, tolerance, current rating, and shielding specifications. Variations in DC resistance (930mOhm maximum versus 780mOhm) and core material (ferrite drum core versus standard wirewound) remain within acceptable substitution parameters for this product category, provided circuit design accommodates the higher DCR specification.

Engineering Selection Recommendations

The B82464G4474M000 is the qualified substitute for the obsolete ELL-ATP471MB. Selection is based on the following engineering criteria:

Compliance & Availability: The substitute maintains ROHS3 compliance and MSL Level 1 rating, matching the original specification. The substitute is currently in active production status with 3034 units in stock, ensuring supply chain continuity for the obsolete original part.

Electrical Equivalence: Both parts meet the 470 µH inductance requirement at ±20% tolerance and support 500 mA continuous current operation. The substitute's higher saturation current (550mA versus 470mA) provides additional margin in saturation performance.

Thermal & Environmental: The substitute specifies an operating temperature range of -55°C to 150°C and includes AEC-Q200 automotive qualification, exceeding the original part's environmental specifications.

Physical Considerations: Dimensional differences are minimal (10.40mm x 10.40mm versus 10.00mm x 10.00mm footprint; 4.80mm versus 4.50mm height). PCB layout verification is required to confirm clearance compatibility with the slightly larger substitute package.

Frequently Asked Questions (FAQ)

Q: Can the B82464G4474M000 directly replace the ELL-ATP471MB in existing designs?

A: Yes, provided the following conditions are met: (1) PCB layout accommodates the slightly larger footprint (10.40mm x 10.40mm versus 10.00mm x 10.00mm) and increased height (4.80mm versus 4.50mm); (2) circuit design tolerates the higher DC resistance specification (930mOhm maximum versus 780mOhm); (3) thermal management accounts for increased power dissipation from the higher DCR value.

Q: What is the impact of the higher DC resistance in the substitute part?

A: The B82464G4474M000 exhibits 930mOhm maximum DCR compared to 780mOhm in the original part. At 500 mA operation, this results in approximately 0.465 watts additional power dissipation in the substitute versus 0.390 watts in the original. Circuit thermal design must accommodate this 19% increase in power loss.

Q: Are there packaging differences between these parts?

A: Both parts use surface mount technology with nonstandard package configurations. The substitute is supplied in Tape & Reel (TR) packaging, while the original part packaging format is not specified. Verify reel compatibility with assembly equipment before production implementation.

Q: What certifications does the substitute part carry?

A: The B82464G4474M000 carries AEC-Q200 automotive qualification in addition to ROHS3 compliance and MSL Level 1 rating, matching or exceeding the original part's compliance profile.

Q: Is the substitute part suitable for high-frequency applications?

A: The substitute specifies a self-resonant frequency of 2.6MHz. Both parts are tested at 100 kHz inductance measurement frequency. Applications requiring operation significantly above 100 kHz should evaluate the self-resonant frequency specification to ensure adequate inductive behavior in the target frequency band.
