Substitute Part Grouping Explanation

Substitute parts for the ELL-8TP470MB must satisfy the following criteria:

• Inductance Value: 47 µH (exact match required)
• Shielding: Shielded construction
• Mounting Type: Surface mount
• Current Capability: Minimum 1.5 A rating
• DC Resistance: Within acceptable operating parameters for the application
• Operating Temperature: Minimum -40°C to 105°C range
• Compliance: ROHS3 compliant, MSL 1 rating

The SRU1038-470Y from Bourns Inc. meets these substitution criteria with compatible electrical and mechanical characteristics suitable for direct replacement in surface mount applications.

Parameter Comparison

Engineering Selection Recommendations

The SRU1038-470Y is suitable as a substitute for the ELL-8TP470MB based on the following factors:

• Both components are ROHS3 compliant and carry MSL 1 rating, ensuring equivalent environmental and regulatory compliance
• The SRU1038-470Y maintains the required 47 µH inductance value with compatible current ratings (1.65 A vs. 1.5 A)
• The substitute part is currently active in production, providing reliable supply chain availability compared to the obsolete ELL-8TP470MB
• Operating temperature range of the substitute (-40°C to 125°C) exceeds the original specification (-40°C to 105°C)
• Physical footprint differences (10.00mm × 10.00mm vs. 8.00mm × 8.00mm) and height variation (4.10mm vs. 5.00mm) require PCB layout verification before implementation

Frequently Asked Questions (FAQ)

Q: Can the SRU1038-470Y be used as a direct replacement for the ELL-8TP470MB?

A: The SRU1038-470Y is electrically compatible as a substitute. However, the larger footprint (10.00mm × 10.00mm vs. 8.00mm × 8.00mm) and different terminal configuration require PCB layout modification. Physical space availability on the circuit board must be confirmed before substitution.

Q: What is the impact of the increased DC resistance in the SRU1038-470Y?

A: The SRU1038-470Y has 121 mOhm DCR compared to 100 mOhm in the ELL-8TP470MB. This 21 mOhm increase results in higher power dissipation. Thermal performance and circuit behavior must be evaluated for applications sensitive to inductor losses.

Q: Are there compliance differences between these parts?

A: Both components are ROHS3 compliant with MSL 1 rating. No compliance barriers exist for substitution from a regulatory standpoint.

Q: Why is the inductance tolerance different?

A: The ELL-8TP470MB specifies ±20% tolerance while the SRU1038-470Y specifies ±30%. Circuit designs must accommodate the wider tolerance range of the substitute part to ensure performance specifications are maintained.

Q: What is the significance of the product status difference?

A: The ELL-8TP470MB is obsolete, making future procurement difficult. The SRU1038-470Y is active in production, ensuring long-term availability and supply chain stability for new designs or ongoing production requirements.
