Substitute Part Grouping Explanation

Substitution of the 13R333C is permissible with parts meeting the following criteria:

• Inductance value of 33 µH with ±10% tolerance
• Current rating equal to or greater than 1.8 A
• DC resistance (DCR) equal to or less than 92mOhm
• Unshielded configuration
• Through-hole radial, vertical cylinder mounting
• ROHS3 compliance
• Operating temperature range that encompasses or exceeds -40°C to 85°C

The RLB9012-330KL from Bourns Inc. satisfies all substitution criteria, offering improved current handling capacity and extended temperature range while maintaining electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the 13R333C and RLB9012-330KL are active products with ROHS3 compliance and REACH unaffected status. The RLB9012-330KL provides enhanced performance margins through higher current rating (2.05 A versus 1.8 A), lower DC resistance (90mOhm versus 92mOhm), and extended operating temperature range (-55°C to 125°C versus -40°C to 85°C). Selection between these parts should be based on inventory availability, lead time requirements, and application-specific thermal or current margin considerations.

Frequently Asked Questions (FAQ)

Q: Can the RLB9012-330KL directly replace the 13R333C in existing designs?

A: Yes. Both parts share identical inductance (33 µH), tolerance (±10%), shielding (unshielded), mounting type (through-hole), and package configuration (radial, vertical cylinder). The RLB9012-330KL meets or exceeds all electrical specifications of the 13R333C.

Q: What are the physical dimension differences between these parts?

A: The 13R333C has a diameter of 0.374" (9.50mm) and seated height of 0.531" (14.60mm). The RLB9012-330KL has a diameter of 0.354" (9.00mm) and seated height of 0.480" (12.20mm). Both are radial, vertical cylinder configurations suitable for through-hole PCB mounting.

Q: Are there compliance or certification differences?

A: Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. No compliance barriers exist for substitution.

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

A: The RLB9012-330KL operates to 125°C maximum, compared to 85°C for the 13R333C. For applications requiring extended temperature performance, the RLB9012-330KL is the appropriate selection.

Q: What is the impact of lower DC resistance in the RLB9012-330KL?

A: Lower DC resistance (90mOhm versus 92mOhm) results in reduced resistive losses and lower heat generation at rated current, improving efficiency and thermal performance in the application circuit.
