Equivalent & Substitute Parts for 13R155C

Part Overview

The 13R155C is a 1.5 mH unshielded wirewound inductor manufactured by Murata Power Solutions Inc., rated for 280 mA maximum current with 3.1 Ohm DC resistance. This through-hole radial component operates across -40°C to 85°C and is ROHS3 compliant. The part remains in active production status with substantial inventory availability. Substitute parts are identified when equivalent inductance values, tolerance specifications, and mounting configurations align with application requirements while accommodating variations in current ratings and thermal operating ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 13R155C is determined by the following critical parameters:

• Inductance Value: Must be 1.5 mH with ±10% tolerance
• Mounting Configuration: Through-hole radial, vertical cylinder package required
• Shielding Type: Unshielded construction
• Compliance: ROHS3 compliance mandatory

The RLB9012-152KL qualifies as a substitute based on matching inductance (1.5 mH ±10%), identical mounting type (through-hole radial), unshielded construction, and equivalent ROHS3 compliance. Variations in current rating (430 mA vs. 280 mA), DC resistance (3.8 Ohm vs. 3.1 Ohm), and operating temperature range (-55°C ~ 125°C vs. -40°C ~ 85°C) represent parameter differences that must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the 13R155C and RLB9012-152KL maintain active production status with ROHS3 compliance and REACH unaffected designation. Selection between these parts depends on application-specific current and thermal requirements. The RLB9012-152KL supports higher current operation (430 mA vs. 280 mA) and extended temperature range (-55°C ~ 125°C vs. -40°C ~ 85°C), making it suitable for applications requiring enhanced thermal or current margin. The 13R155C offers lower DC resistance (3.1 Ohm vs. 3.8 Ohm), which may be advantageous in applications sensitive to resistive losses. Both components satisfy identical inductance, tolerance, mounting, and compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can RLB9012-152KL directly replace 13R155C in all applications?

A: Direct replacement is valid when application current requirements do not exceed 280 mA and operating temperature remains within -40°C to 85°C. The RLB9012-152KL's higher current rating (430 mA) and extended temperature range provide additional operational margin but do not restrict use in lower-demand applications. DC resistance difference (3.8 Ohm vs. 3.1 Ohm) must be evaluated for circuits sensitive to resistive losses.

Q: What are the critical matching parameters for substitution?

A: Inductance value (1.5 mH ±10%), mounting type (through-hole radial vertical cylinder), shielding configuration (unshielded), and compliance certification (ROHS3) must match exactly. These parameters define functional equivalence in circuit applications.

Q: How do the physical dimensions compare?

A: 13R155C measures 0.374" diameter (9.50 mm) with 0.531" maximum seated height (14.60 mm). RLB9012-152KL measures 0.354" diameter (9.00 mm) with 0.480" maximum seated height (12.20 mm). Both fit standard through-hole radial footprints, though dimensional differences may affect PCB layout spacing.

Q: Are there temperature range limitations for substitution?

A: The 13R155C operates -40°C to 85°C. Applications requiring operation below -40°C or above 85°C must use RLB9012-152KL (-55°C ~ 125°C). Verify application temperature requirements before selection.

Q: What packaging differences exist?

A: 13R155C ships in bulk packaging; RLB9012-152KL ships in tray packaging. This affects procurement and handling but does not impact electrical performance or circuit compatibility.
