Murata 13R335C Equivalent & Substitute Parts

Part Overview

The Murata 13R335C is a 3.3 mH unshielded wirewound inductor rated for 190 mA maximum current with 7 Ohm DC resistance. This through-hole radial component operates across -40°C to 85°C and is part of the 1300R series. The part maintains active product status and is ROHS3 compliant. Substitute parts are identified when equivalent inductance values, current ratings, and mounting configurations are required for design flexibility, inventory management, or supply chain continuity.

Substitute Part Grouping Explanation

Substitution eligibility for the Murata 13R335C is determined by the following criteria:

• Inductance value must be 3.3 mH with ±10% tolerance
• Current rating must meet or exceed 190 mA
• DC resistance must be compatible with circuit requirements
• Mounting type must be through-hole with radial, vertical cylinder configuration
• Shielding classification must be unshielded
• Component type must be wirewound construction
• RoHS3 compliance is required

The Bourns RLB9012-332KL satisfies these substitution parameters while offering enhanced current handling (290 mA) and extended operating temperature range (-55°C ~ 125°C).

Parameter Comparison

Engineering Selection Recommendations

Both the Murata 13R335C and Bourns RLB9012-332KL are active products with ROHS3 compliance and REACH unaffected status. The Bourns substitute provides higher current capacity (290 mA versus 190 mA) and wider operating temperature range (-55°C ~ 125°C versus -40°C ~ 85°C). DC resistance increases from 7 Ohm to 9.1 Ohm maximum, which must be evaluated against circuit power dissipation requirements. Both components maintain identical inductance values and tolerance specifications at 1 kHz test frequency. Selection between these parts depends on thermal environment requirements and current margin specifications for the application.

Frequently Asked Questions (FAQ)

Q: Can the Bourns RLB9012-332KL directly replace the Murata 13R335C?

A: Yes, provided that the increased DC resistance (9.1 Ohm versus 7 Ohm) and higher current rating (290 mA versus 190 mA) are compatible with circuit design parameters. Both components share identical inductance values, tolerance, mounting type, and package configuration.

Q: What is the impact of the higher DC resistance in the Bourns substitute?

A: The 2.1 Ohm increase in maximum DC resistance will result in higher power dissipation at equivalent current levels. Circuit thermal analysis must confirm that this additional dissipation remains within acceptable limits for the application.

Q: Are there physical dimension differences between these parts?

A: Yes. The Murata 13R335C has a diameter of 0.374" (9.50 mm) and height of 0.531" (14.60 mm). The Bourns RLB9012-332KL has a diameter of 0.354" (9.00 mm) and height of 0.480" (12.20 mm). PCB layout and clearance requirements must be verified before substitution.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the Murata 13R335C and Bourns RLB9012-332KL are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99.

Q: What is the difference in operating temperature ranges?

A: The Murata 13R335C operates from -40°C to 85°C, while the Bourns RLB9012-332KL operates from -55°C to 125°C. The Bourns part provides extended temperature capability for applications requiring wider thermal operating windows.
