ELL-6RH3R3M Equivalent & Substitute Parts

Part Overview

The ELL-6RH3R3M is a 3.3 µH shielded wirewound inductor manufactured by Panasonic Electronic Components, rated for 1.6 A with a DC resistance of 44mOhm. This component is classified as obsolete, making equivalent substitutes necessary for new designs and ongoing production requirements. The part operates at 100 kHz inductance test frequency and is mounted as a surface mount device in a nonstandard package measuring 6.40mm × 6.00mm × 2.80mm (max height).

Key Parameters

Substitute Part Grouping Explanation

Substitution for the ELL-6RH3R3M is determined by the following critical parameters:

• Inductance Value: Must be 3.3 µH with ±20% tolerance
• Current Rating: Minimum 1.6 A; higher ratings provide design margin
• DC Resistance: Lower DCR values reduce power dissipation and heat generation
• Shielding Configuration: Shielded construction minimizes electromagnetic interference
• Mounting Type: Surface mount compatibility required
• Inductance Test Frequency: 100 kHz reference standard
• Compliance: ROHS3 compliance and MSL 1 rating required

The two substitute parts listed below maintain the core inductance specification and mounting compatibility while offering improved current ratings and reduced DC resistance compared to the obsolete ELL-6RH3R3M.

Parameter Comparison

Engineering Selection Recommendations

B82462G4332M000 is the primary substitute for the ELL-6RH3R3M. This part maintains shielded construction matching the original design, offers superior current rating (2.3 A vs. 1.6 A), and provides lower DC resistance (31mOhm Max vs. 44mOhm). The part is manufactured by EPCOS - TDK Electronics with active product status, AEC-Q200 rating, and full ROHS3 compliance. Operating temperature range of -55°C to 150°C exceeds typical industrial requirements.

B82462A4332M000 serves as an alternative substitute with higher current rating (2 A) and active product status. However, this part features unshielded construction, which differs from the original shielded design. Selection of this part requires verification that electromagnetic shielding is not critical to circuit performance. The 60mOhm Max DC resistance is higher than both the original part and the B82462G4332M000 alternative.

Both substitute parts are available in Tape & Reel packaging with unlimited moisture sensitivity level rating, suitable for automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can B82462A4332M000 replace ELL-6RH3R3M directly?

A: B82462A4332M000 meets the inductance, tolerance, and current rating requirements. However, it is unshielded while the original is shielded. Direct substitution is valid only if electromagnetic shielding is not required for circuit operation. The higher DC resistance (60mOhm Max) may increase power dissipation compared to the original 44mOhm specification.

Q: Why is B82462G4332M000 preferred over B82462A4332M000?

A: B82462G4332M000 maintains shielded construction identical to the original ELL-6RH3R3M, provides superior current rating (2.3 A), and offers lower DC resistance (31mOhm Max). These characteristics make it the closest functional equivalent for designs requiring electromagnetic isolation.

Q: Are there package compatibility concerns?

A: All three parts use surface mount technology with nonstandard packages. Physical dimensions vary slightly: ELL-6RH3R3M measures 6.40mm × 6.00mm × 2.80mm (max height), B82462A4332M000 measures 6.00mm × 6.00mm × 3.00mm (max height), and B82462G4332M000 measures 6.30mm × 6.30mm × 3.00mm (max height). PCB layout verification is required to confirm fit within available space.

Q: What compliance certifications apply to substitute parts?

A: Both B82462A4332M000 and B82462G4332M000 are ROHS3 compliant, AEC-Q200 rated, and REACH unaffected. MSL rating is 1 (Unlimited) for both parts, matching the original specification.

Q: Can these parts be used interchangeably in production?

A: B82462G4332M000 is the direct equivalent for production use. B82462A4332M000 requires circuit-level evaluation due to shielding differences. Both parts are available in Tape & Reel packaging suitable for automated assembly.
