Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 11R104C is determined by the following critical parameters:

Electrical Equivalence Criteria:

• Inductance value of 100 µH within ±10% tolerance
• Current rating sufficient to support 350 mA operation
• DC resistance compatible with circuit design requirements

Mechanical Compatibility Criteria:

• Through-hole mounting configuration
• Radial, vertical cylinder package geometry
• Physical dimensions: 5.00 mm diameter, 7.50 mm maximum height
• Unshielded construction

Environmental & Compliance Criteria:

• Operating temperature range encompassing -40°C to 85°C minimum
• ROHS3 compliance
• REACH unaffected status

The RLB0608-101KL from Bourns Inc. meets all mechanical and compliance requirements. Electrical parameters show variations in current rating (305 mA vs. 350 mA) and DC resistance (1.7 Ohm vs. 1.1 Ohm), which must be evaluated against specific circuit requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the 11R104C and RLB0608-101KL maintain active product status and full regulatory compliance under ROHS3 and REACH requirements. Selection between these components depends on circuit-specific electrical requirements:

The 11R104C provides a lower DC resistance specification (1.1 Ohm maximum) and higher current rating (350 mA), making it suitable for applications where power dissipation and current capacity are primary design constraints.

The RLB0608-101KL offers an extended operating temperature range to 105°C and is available in higher inventory quantity (2069 units), providing thermal margin for elevated ambient conditions and supply chain flexibility.

Both components share identical mechanical form factors and inductance values, ensuring direct PCB compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can RLB0608-101KL replace 11R104C in all applications?

A: Mechanical and inductance compatibility is confirmed. Electrical compatibility requires verification that the 305 mA current rating and 1.7 Ohm DC resistance are acceptable for the specific circuit. If the application requires the full 350 mA rating or lower resistance, the 11R104C is the appropriate choice.

Q: What is the impact of the 0.6 Ohm DC resistance difference?

A: The RLB0608-101KL exhibits 0.6 Ohm higher DC resistance. In circuits where inductor losses contribute significantly to thermal budget or efficiency calculations, this difference must be evaluated against design margins.

Q: Are the physical packages identical?

A: Yes. Both components are specified as radial, vertical cylinder packages with 5.00 mm diameter and 7.50 mm maximum height, ensuring identical PCB footprint and mounting compatibility.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the 11R104C and RLB0608-101KL are ROHS3 compliant and REACH unaffected, meeting equivalent environmental and regulatory standards.

Q: Which part should be selected for high-temperature applications?

A: The RLB0608-101KL supports operation to 105°C, providing 20°C additional thermal margin compared to the 11R104C specification of 85°C maximum.
