Substitute Part Grouping Explanation

The UP1B-150-R qualifies as a direct substitute for the SC2506-150 based on the following critical parameters:

• Inductance Match: Both parts specify 15 µH at 100 kHz test frequency with ±20% tolerance
• Shielding Configuration: Both are unshielded inductors
• Mounting Technology: Both use surface mount assembly
• Regulatory Compliance: Both are ROHS3 compliant and REACH unaffected
• Moisture Sensitivity: Both rated MSL 1 (Unlimited)

The UP1B-150-R provides enhanced performance characteristics including higher current rating (1.2 A vs. 900 mA), lower DC resistance (174.7 mOhm vs. 300 mOhm), and active product status with defined operating temperature range (-40°C to 85°C).

Parameter Comparison

Engineering Selection Recommendations

The UP1B-150-R is the qualified substitute for SC2506-150 applications. Selection is supported by:

• Regulatory Alignment: Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory continuity
• Product Lifecycle: The UP1B-150-R carries active product status with defined operating temperature specifications, providing long-term supply assurance compared to the obsolete SC2506-150
• Performance Enhancement: The substitute delivers superior electrical characteristics with 33% higher current rating and 42% lower DC resistance, providing design margin in current-limited applications
• Certification Consistency: Identical moisture sensitivity rating and compliance certifications ensure drop-in compatibility in existing manufacturing processes

Frequently Asked Questions (FAQ)

Q: Can UP1B-150-R directly replace SC2506-150 in existing designs?

A: Yes. Both inductors share identical inductance (15 µH), tolerance (±20%), shielding configuration (unshielded), and test frequency (100 kHz). Surface mount mounting type and regulatory compliance are equivalent. Physical package dimensions differ; mechanical fit verification is required.

Q: What are the key differences between these inductors?

A: The UP1B-150-R provides higher current rating (1.2 A vs. 900 mA), lower DC resistance (174.7 mOhm vs. 300 mOhm), and active product status. The substitute uses ferrite drum core wirewound construction versus the SC2506-150's unspecified core material. Operating temperature range is defined for UP1B-150-R (-40°C to 85°C) but not specified for SC2506-150.

Q: Are there physical compatibility concerns?

A: Physical dimensions differ. SC2506-150 measures 9.25mm L × 7.87mm W × 1.65mm H (seated). UP1B-150-R measures 8.89mm L × 6.10mm W × 5.00mm H (seated). PCB layout and clearance verification is necessary before substitution.

Q: Does the substitute meet the same compliance requirements?

A: Yes. Both components are ROHS3 compliant, REACH unaffected, and rated MSL 1 (Unlimited). Regulatory and environmental compliance are equivalent.

Q: Why is UP1B-150-R recommended over SC2506-150?

A: SC2506-150 is obsolete. UP1B-150-R is active with defined specifications, ensuring supply continuity and long-term availability. The substitute also provides enhanced electrical performance with lower resistance and higher current capacity.
