SC5022C-102 Equivalent & Substitute Parts

Part Overview

The SC5022C-102 is a 1 mH shielded inductor manufactured by Signal Transformer, designed for surface mount applications requiring fixed inductance in compact form factors. This component is rated for 540 mA continuous current with a maximum DC resistance of 2.01 Ohm and operates across the temperature range of -40°C to 125°C. The part maintains Active product status and is RoHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when equivalent electrical performance can be maintained across critical parameters including inductance value, current rating, DC resistance, shielding characteristics, and operating temperature specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the SC5022C-102 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Inductance value: 1 mH (±20% tolerance maintained)
• DC Resistance: 2.01 Ohm maximum
• Current Rating: minimum 530 mA (acceptable variance within design margin)
• Saturation Current: 800 mA minimum
• Shielding: Shielded construction required

Environmental & Compliance Requirements:

• Operating Temperature: minimum -40°C to 85°C (acceptable if upper limit meets or exceeds application requirements)
• Mounting: Surface Mount only
• RoHS Status: RoHS3 Compliant
• MSL Rating: 1 (Unlimited)

Physical Requirements:

• Package Type: Nonstandard (dimensional compatibility required)
• Height - Seated: 0.300" (7.62mm) maximum

The ASPI-1306S-102M-T from Abracon LLC meets all substitution criteria within these defined parameters.

Engineering Selection Recommendations

Both the SC5022C-102 and ASPI-1306S-102M-T maintain Active product status and full RoHS3 compliance with unlimited moisture sensitivity ratings, supporting long-term supply chain stability and regulatory adherence.

The primary consideration for component selection is the operating temperature upper limit. The SC5022C-102 operates to 125°C, while the ASPI-1306S-102M-T operates to 85°C. Applications requiring sustained operation above 85°C must retain the original SC5022C-102 specification. For applications with maximum operating temperatures at or below 85°C, the ASPI-1306S-102M-T provides functional equivalence.

Current rating variance of 10 mA (540 mA versus 530 mA) falls within acceptable design margins for most applications, with both parts sharing identical saturation current and DC resistance specifications.

Physical dimensions show minor variation (approximately 1% difference in length and width), with both parts maintaining the same seated height of 0.300 inches, ensuring compatibility with standard PCB layouts and assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the ASPI-1306S-102M-T replace the SC5022C-102 in all applications?

A: Substitution is valid for applications where the maximum operating temperature does not exceed 85°C. The SC5022C-102 supports operation to 125°C. Verify your application's thermal requirements before substitution.

Q: What is the significance of the 10 mA current rating difference?

A: The SC5022C-102 is rated for 540 mA continuous current, while the ASPI-1306S-102M-T is rated for 530 mA. Both parts share the same 800 mA saturation current. This 1.9% variance is within typical design margins for inductor applications and does not affect functional equivalence for standard circuit designs.

Q: Are the physical dimensions compatible with existing PCB layouts?

A: Both parts maintain identical seated height (0.300 inches / 7.62mm) and nonstandard package types. Length and width dimensions differ by approximately 1%, with the ASPI-1306S-102M-T being slightly smaller. Verify PCB footprint clearances and mounting area constraints for your specific layout before substitution.

Q: Do both parts meet the same compliance and regulatory standards?

A: Yes. Both the SC5022C-102 and ASPI-1306S-102M-T are RoHS3 compliant, REACH unaffected, classified under ECCN EAR99, and carry MSL 1 (Unlimited) ratings. Regulatory and environmental compliance requirements are equivalent.

Q: What is the core material difference between these inductors?

A: The SC5022C-102 core material is not specified in the available data. The ASPI-1306S-102M-T uses a ferrite drum core with wirewound construction. Both achieve identical inductance, tolerance, and DC resistance specifications at the 100 kHz test frequency.

Q: Is the self-resonant frequency specification important for substitution?

A: The ASPI-1306S-102M-T specifies a self-resonant frequency of 800 kHz. The SC5022C-102 self-resonant frequency is not provided in the available data. For applications sensitive to high-frequency behavior, obtain complete frequency response characteristics before substitution.
