Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ELL-6RH470M are selected based on the following critical parameters:

• Inductance Value: Must be 47 µH to maintain circuit functionality
• Current Rating: Minimum 500 mA required; higher ratings are acceptable
• DC Resistance: Must not exceed design limits; lower DCR values improve efficiency
• Shielding: Shielded construction required to prevent electromagnetic interference
• Mounting Type: Surface mount configuration mandatory for PCB compatibility
• Package Dimensions: Physical footprint must fit within design constraints
• Compliance: RoHS3 compliance and MSL 1 rating required

Two substitute parts meet these criteria: CDRH62BNP-470MC-B (Sumida America Components Inc.) and SRR5028-470Y (Bourns Inc.). Both maintain the 47 µH inductance, shielded construction, and surface mount configuration while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

CDRH62BNP-470MC-B is suitable for applications where the original ELL-6RH470M specifications are maintained. This substitute offers active product status with 53,170 units in stock, ensuring long-term availability. The ferrite core construction and slightly higher DCR (690mOhm max) are acceptable for most circuit designs. The operating temperature range of -40°C to 100°C covers standard industrial applications. RoHS3 compliance and MSL 1 rating match the original part requirements.

SRR5028-470Y provides enhanced performance characteristics with a lower DC resistance (250mOhm max) and higher current rating (820 mA), making it suitable for applications requiring improved efficiency and thermal performance. The smaller footprint (5.80mm x 5.80mm) offers space savings in compact designs. The extended operating temperature range (-40°C to 125°C) and active product status support demanding applications. RoHS3 compliance and MSL 1 rating are maintained. The ±30% tolerance is wider than the original specification and must be evaluated against circuit requirements.

Both substitutes maintain RoHS3 compliance, MSL 1 rating, and shielded surface mount construction. Selection between them depends on PCB space constraints, thermal requirements, and tolerance specifications for the target application.

Frequently Asked Questions (FAQ)

Q: Can CDRH62BNP-470MC-B directly replace ELL-6RH470M? A: Yes, for applications where the 500 mA current rating and ±20% tolerance are sufficient. The slightly higher DCR (690mOhm max vs. 480mOhm) must be verified against circuit performance requirements. Physical dimensions are comparable (6.60mm x 6.20mm vs. 6.40mm x 6.00mm), with maximum height of 3.00mm vs. 2.80mm.

Q: What are the advantages of SRR5028-470Y as a substitute? A: The SRR5028-470Y offers lower DC resistance (250mOhm max), higher current rating (820 mA), and a smaller footprint (5.80mm x 5.80mm). These characteristics reduce power dissipation and enable compact PCB layouts. The extended operating temperature range (-40°C to 125°C) supports wider environmental conditions.

Q: Does the ±30% tolerance of SRR5028-470Y affect circuit compatibility? A: The wider tolerance must be evaluated against circuit design margins. If the original design relied on the ±20% tolerance of ELL-6RH470M, circuit simulation or testing is necessary to confirm acceptable performance with the ±30% tolerance of SRR5028-470Y.

Q: Are all substitutes RoHS3 compliant? A: Yes, both CDRH62BNP-470MC-B and SRR5028-470Y are RoHS3 compliant with MSL 1 rating, matching the original ELL-6RH470M specifications.

Q: What is the impact of different inductance test frequencies? A: ELL-6RH470M and SRR5028-470Y are tested at 100 kHz, while CDRH62BNP-470MC-B is tested at 1 kHz. This difference reflects measurement methodology and does not affect substitution validity, as all parts are specified at 47 µH nominal inductance.

Q: Can I use these substitutes in high-temperature applications? A: CDRH62BNP-470MC-B operates to 100°C, while SRR5028-470Y operates to 125°C. If the original application did not specify operating temperature limits, verify that the substitute's temperature range meets your design requirements.
