Substitute Part Grouping Explanation

Substitution of the 34154C is permissible with the Bourns SRR4018-151Y based on the following alignment of critical electrical parameters:

Matching Parameters:

• Inductance value: 150 µH (both parts)
• Shielding classification: Shielded (both parts)
• Operating temperature range: -40°C to 125°C (both parts)
• Mounting type: Surface Mount (both parts)
• RoHS3 compliance: Both parts meet ROHS3 Compliant status

Acceptable Parameter Variance:

• Current rating: SRR4018-151Y rated at 280 mA exceeds the 34154C requirement of 230 mA
• DC resistance: SRR4018-151Y maximum of 2.6Ohm is within acceptable tolerance relative to 34154C maximum of 2.4Ohm
• Inductance tolerance: SRR4018-151Y tolerance of ±30% encompasses the 34154C tolerance of ±20%

Mechanical Compatibility:

• Both components feature identical maximum seated height of 0.079" (2.00mm)
• Package footprints are comparable in surface mount configuration

Parameter Comparison

Engineering Selection Recommendations

Selection between the 34154C and SRR4018-151Y is determined by availability, lead time, and supply chain requirements. Both components maintain Active product status and satisfy ROHS3 compliance obligations. The SRR4018-151Y provides higher current rating headroom (280 mA versus 230 mA) and wider inductance tolerance specification, making it suitable for applications where component margin is prioritized. The 34154C remains the primary selection when original manufacturer specification and tighter tolerance control are required. Both parts are qualified for the full industrial temperature range and maintain identical mechanical form factor for PCB layout compatibility.

Frequently Asked Questions (FAQ)

Q: Can the SRR4018-151Y directly replace the 34154C in production?

A: Yes. Both components share identical inductance value, shielding classification, operating temperature range, mounting type, and seated height. The SRR4018-151Y exceeds the current rating requirement and maintains compatible DC resistance specification.

Q: What is the impact of the ±30% tolerance on the SRR4018-151Y versus ±20% on the 34154C?

A: The wider tolerance on the SRR4018-151Y does not prevent substitution when the application circuit design accommodates the specified tolerance band. Circuit performance must be verified within the tolerance envelope of either component.

Q: Are there mechanical footprint differences between these parts?

A: Both components are surface mount inductors with identical maximum seated height of 2.00mm. Footprint dimensions are comparable, though the 34154C measures 5.20mm x 5.20mm while the SRR4018-151Y measures 4.80mm x 4.80mm. PCB layout verification is required for final placement confirmation.

Q: Do both parts meet regulatory compliance requirements?

A: Yes. Both the 34154C and SRR4018-151Y are ROHS3 Compliant, REACH Unaffected, and classified under ECCN EAR99 with identical HTSUS code 8504.50.4000.

Q: What is the saturation current consideration for the SRR4018-151Y?

A: The SRR4018-151Y specifies a saturation current (Isat) of 260mA. This parameter is not provided for the 34154C. Applications operating near or above 230 mA should reference the SRR4018-151Y saturation specification to ensure adequate margin.
