SC5022C-151 Equivalent & Substitute Parts

Part Overview

The SC5022C-151 is a 150 µH shielded inductor manufactured by Signal Transformer, designed for surface mount applications requiring fixed inductance in compact form factors. This component is rated for 1.5 A continuous current with a maximum DC resistance of 293 mOhm and operates across the temperature range of -40°C to 125°C. The part maintains Active product status and is RoHS3 compliant. Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the specified parameter tolerances for this inductance category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SC5022C-151 is determined by the following critical parameters:

• Inductance Value: 150 µH ±20% tolerance
• Current Rating: Minimum 1.3 A (substitute must support primary application current requirements)
• DC Resistance: 293 mOhm maximum (electrical performance equivalence)
• Saturation Current: 2.1 A (magnetic performance threshold)
• Shielding: Shielded configuration (electromagnetic containment requirement)
• Mounting Type: Surface Mount (PCB integration compatibility)
• Operating Temperature: Minimum -40°C to 85°C overlap (thermal operating window)
• Compliance: RoHS3 and REACH status alignment

The ASPI-1306S-151M-T from Abracon LLC meets these substitution criteria with matching inductance, saturation current, DC resistance, shielding, and compliance certifications. The 1.3 A current rating of the substitute is lower than the primary part's 1.5 A rating; therefore, application current requirements must not exceed 1.3 A for direct substitution.

Parameter Comparison

Engineering Selection Recommendations

The ASPI-1306S-151M-T qualifies as a direct substitute for the SC5022C-151 when application requirements align with the following conditions:

• Circuit current draw does not exceed 1.3 A continuous operation
• Operating temperature environment remains within -40°C to 85°C
• RoHS3 and REACH compliance requirements are maintained
• Shielded inductor configuration is required for electromagnetic performance

Both parts maintain Active product status, identical inductance specifications, matching saturation current thresholds, and equivalent DC resistance characteristics. The substitute part is available in higher inventory quantity (887 Pcs versus 670 Pcs), supporting supply chain continuity. Mechanical dimensions differ slightly (SC5022C-151: 19.04mm × 15.74mm; ASPI-1306S-151M-T: 18.54mm × 15.24mm), with both maintaining 7.62mm maximum seated height for PCB clearance compatibility.

Frequently Asked Questions (FAQ)

Q: Can the ASPI-1306S-151M-T replace the SC5022C-151 in all applications?

A: Substitution is valid when application current requirements do not exceed 1.3 A and operating temperature remains within -40°C to 85°C. If the primary application requires sustained current above 1.3 A or operates above 85°C, the SC5022C-151 must be retained.

Q: What is the significance of the 1.5 A versus 1.3 A current rating difference?

A: The current rating indicates the maximum continuous current the inductor can handle without exceeding thermal limits. The SC5022C-151 supports higher current applications. For circuits operating below 1.3 A, both parts perform identically.

Q: Are the physical dimensions compatible for PCB layout?

A: Both parts are surface mount with identical maximum seated height (7.62mm). Footprint dimensions differ slightly but remain within nonstandard package classifications. PCB layout verification is required to confirm clearance compatibility with specific board designs.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the SC5022C-151 and ASPI-1306S-151M-T are RoHS3 compliant and REACH unaffected, meeting equivalent regulatory requirements for industrial and commercial applications.

Q: What is the operating temperature consideration for substitution?

A: The SC5022C-151 operates to 125°C maximum, while the ASPI-1306S-151M-T operates to 85°C maximum. Applications requiring operation above 85°C require the primary part. Applications within -40°C to 85°C can use either part.
