Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 13R152C is determined by the following critical parameters:

• Inductance Value: Must be 1.5 µH with ±20% tolerance to maintain circuit performance
• Current Rating: Substitute must support minimum 6.3 A; higher ratings are acceptable
• DC Resistance: Maximum 8 mOhm specification; lower values are acceptable
• Mounting Type: Through hole radial configuration required for PCB compatibility
• Package Form Factor: Radial, vertical cylinder geometry for mechanical fit
• Shielding Classification: Unshielded category maintained
• Compliance: ROHS3 compliance required

The RLB9012-1R5ML meets these substitution criteria with equivalent inductance and tolerance, higher current capacity (8.5 A), and compatible through-hole radial packaging.

Parameter Comparison

Engineering Selection Recommendations

Both the 13R152C and RLB9012-1R5ML are Active status products with ROHS3 compliance and REACH unaffected designation. Selection between these components should be based on application-specific requirements:

The 13R152C provides lower DC resistance (8 mOhm maximum) suitable for applications prioritizing minimal power dissipation. The RLB9012-1R5ML offers higher current capacity (8.5 A versus 6.3 A) and extended operating temperature range (-55°C to 125°C versus -40°C to 85°C), making it suitable for demanding thermal or high-current environments. The RLB9012-1R5ML exhibits higher DC resistance (16 mOhm maximum), which may increase heat generation in current-limited applications.

Frequently Asked Questions (FAQ)

Q: Can RLB9012-1R5ML replace 13R152C in all applications?

A: Electrical substitution is valid for inductance and tolerance matching. However, the higher DC resistance (16 mOhm vs 8 mOhm) will increase power dissipation. Verify thermal performance in your specific circuit before substitution.

Q: What is the significance of the current rating difference?

A: The RLB9012-1R5ML supports 8.5 A versus the 13R152C's 6.3 A rating. This provides design margin in current-limited applications but does not affect compatibility if your circuit operates below 6.3 A.

Q: Are the physical dimensions compatible?

A: Both components use radial, vertical cylinder packaging. The 13R152C measures 0.374" diameter × 0.531" height; the RLB9012-1R5ML measures 0.354" diameter × 0.480" height. Verify PCB footprint spacing and clearance requirements for your specific layout.

Q: Does operating temperature range affect substitution?

A: The RLB9012-1R5ML operates across -55°C to 125°C versus the 13R152C's -40°C to 85°C range. If your application requires the extended lower temperature limit (-55°C), the RLB9012-1R5ML is required. For standard -40°C to 85°C operation, both are equivalent.

Q: What packaging format differences exist?

A: The 13R152C is supplied in Bulk packaging; the RLB9012-1R5ML is supplied in Tray packaging. Verify your procurement and assembly process compatibility with the respective packaging format.
