Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RL0809-152-R is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 1.5 mH (±10% tolerance band)
• Core type: Ferrite drum core, unshielded
• Mounting configuration: Through-hole, radial vertical cylinder package
• Current handling capability: Minimum 255 mA rating

Secondary Compatibility Factors:

• DC resistance within acceptable circuit performance limits
• Operating temperature range encompassing -40°C to 125°C
• Self-resonant frequency suitable for intended frequency band of operation

The RLB0913-152K from Bourns Inc. meets these substitution criteria with matching inductance, core material, package configuration, and mounting type. The substitute part demonstrates enhanced current rating (285 mA) and extended low-temperature operation (-55°C), providing improved performance margins in the same physical form factor.

Parameter Comparison

Engineering Selection Recommendations

The RLB0913-152K represents a direct functional substitute for the obsolete RL0809-152-R. Both components share identical inductance specifications, ferrite core construction, and through-hole radial package geometry, enabling direct circuit board layout compatibility.

Product Status Consideration: The RL0809-152-R is classified as obsolete, while the RLB0913-152K maintains active production status with confirmed inventory availability. This status differential supports transition to the Bourns component for new designs and ongoing production requirements.

Compliance and Certification: The RLB0913-152K carries ROHS3 compliance certification and REACH unaffected status, meeting current regulatory requirements for electronic component procurement. These certifications support long-term supply chain reliability and regulatory compliance in manufacturing environments subject to environmental directives.

Performance Characteristics: The substitute part demonstrates superior current handling (285 mA versus 255 mA) and extended low-temperature operation (-55°C versus -40°C minimum), providing enhanced performance margins. The increased DC resistance (6.1 Ohm versus 4 Ohm maximum) requires circuit-level evaluation to confirm acceptable power dissipation and voltage drop characteristics within the specific application context.

Frequently Asked Questions (FAQ)

Q: Can the RLB0913-152K be used as a direct replacement for the RL0809-152-R in existing circuit designs?

A: The RLB0913-152K is mechanically and electrically compatible for through-hole mounting in PCB layouts designed for the RL0809-152-R. Both components feature identical 1.5 mH inductance, ±10% tolerance, ferrite core construction, and radial vertical cylinder package configuration. Circuit performance validation is required to confirm acceptable operation with the increased DC resistance of the substitute part.

Q: What is the impact of the higher DC resistance in the RLB0913-152K?

A: The RLB0913-152K exhibits 6.1 Ohm DC resistance compared to 4 Ohm maximum for the RL0809-152-R. This 2.1 Ohm difference increases power dissipation proportionally to the square of the circuit current. Applications operating near the 255 mA rating require thermal analysis to confirm that increased resistive losses remain within acceptable limits for the operating environment.

Q: Are there physical dimension differences between these components?

A: Both parts utilize radial vertical cylinder packages with minor dimensional variations. The RL0809-152-R measures 0.311" diameter (7.90 mm) with 0.354" maximum seated height (9.00 mm). The RLB0913-152K measures 0.335" diameter (8.50 mm) with 0.492" maximum seated height (12.50 mm). PCB layout verification is necessary to confirm clearance compatibility in space-constrained applications.

Q: What are the frequency response differences between these inductors?

A: The RL0809-152-R exhibits a self-resonant frequency of 2 MHz, while the RLB0913-152K operates at 1 MHz self-resonance. Applications utilizing these components in frequency-dependent circuits require evaluation of this parameter difference to confirm suitable performance across the intended operating frequency band.

Q: Does the RLB0913-152K meet current regulatory compliance requirements?

A: The RLB0913-152K carries ROHS3 compliance certification and REACH unaffected status, meeting current environmental and regulatory requirements for electronic component procurement in regulated manufacturing environments. The RL0809-152-R compliance status is not specified in available documentation.
