SRN3010-100M Equivalent & Substitute Parts

Part Overview

The SRN3010-100M is a 10 µH semi-shielded drum core wirewound inductor manufactured by Bourns Inc., rated for 900 mA continuous current with a maximum DC resistance of 420 mOhm. This surface mount component in 1212 (3030 Metric) package is designed for applications requiring compact, high-frequency filtering and energy storage in power conversion circuits.

The SRN3010-100M is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for legacy systems or new designs requiring compatible performance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SRN3010-100M are qualified based on the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Inductance value: 10 µH ±20%
• Package / Case: 1212 (3030 Metric) or equivalent footprint
• Mounting Type: Surface Mount
• Current Rating: minimum 900 mA
• DC Resistance: acceptable range for application requirements
• Operating Temperature Range: minimum -40°C ~ 125°C coverage
• Core Material and Shielding: compatible with electromagnetic environment

Substitute Categories:

MFR Recommended Substitute (Direct Upgrade): SRN3010C-100M is the manufacturer-recommended successor from Bourns Inc. This part maintains identical inductance, package, and core material specifications while offering improved current handling (1.1 A vs. 900 mA) and higher saturation current (800 mA vs. 600 mA). Product status is Active, ensuring long-term availability.

Similar Manufacturer Substitute (Cross-Manufacturer Alternative): ASPI-0310FS-100M-T2 from Abracon LLC provides equivalent inductance and current rating with improved DC resistance (350 mOhm vs. 420 mOhm). This part uses Nickel Zinc Ferrite core material with full shielding instead of semi-shielding, suitable for applications requiring enhanced EMI suppression. Product status is Active.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Preferred): Select SRN3010C-100M when supply chain continuity and identical package specifications are required. This part is the manufacturer-recommended successor with Active product status, ensuring availability and long-term support. The improved current rating and saturation current provide additional design margin without requiring PCB layout modifications.

For Enhanced Performance: Select ASPI-0310FS-100M-T2 when lower DC resistance and improved EMI shielding are beneficial to circuit performance. This part is Active and ROHS3 compliant. Note that the operating temperature minimum is -25°C (versus -40°C for the main part) and the package is classified as nonstandard; verify PCB footprint compatibility before selection.

Compliance Considerations: All three parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. All parts carry MSL 1 (Unlimited) moisture sensitivity rating, requiring standard handling procedures.

Frequently Asked Questions (FAQ)

Q: Can SRN3010C-100M be used as a direct replacement for SRN3010-100M?

A: Yes. Both parts share identical inductance (10 µH), tolerance (±20%), package (1212 / 3030 Metric), mounting type (Surface Mount), operating temperature range (-40°C ~ 125°C), and core material (Ferrite). The SRN3010C-100M offers higher current rating (1.1 A vs. 900 mA) and saturation current (800 mA vs. 600 mA), making it a direct upgrade with no PCB modifications required.

Q: What are the key differences between SRN3010C-100M and ASPI-0310FS-100M-T2?

A: Both maintain 10 µH inductance and 900 mA current rating. Key differences are: (1) DC resistance is lower in ASPI-0310FS-100M-T2 (350 mOhm vs. 504 mOhm), (2) shielding is full versus semi-shielded, (3) core material differs (Nickel Zinc Ferrite vs. Ferrite), (4) operating temperature minimum is -25°C versus -40°C, and (5) package is nonstandard versus standard 1212 metric.

Q: Is the ASPI-0310FS-100M-T2 package footprint compatible with the original SRN3010-100M PCB?

A: The ASPI-0310FS-100M-T2 package is classified as nonstandard. Although physical dimensions are identical (0.118" L x 0.118" W, 3.00mm x 3.00mm), the nonstandard package designation requires verification of PCB footprint compatibility before implementation. Contact the component supplier or manufacturer for detailed package drawings.

Q: What is the impact of different core materials on circuit performance?

A: The SRN3010-100M and SRN3010C-100M use standard Ferrite core material. The ASPI-0310FS-100M-T2 uses Nickel Zinc Ferrite (NiZn), which typically exhibits different frequency response and temperature stability characteristics. Selection depends on specific circuit requirements; no universal performance advantage exists across all applications.

Q: Are all substitute parts RoHS and REACH compliant?

A: Yes. All three parts (SRN3010-100M, SRN3010C-100M, and ASPI-0310FS-100M-T2) are ROHS3 compliant and REACH unaffected, meeting environmental and regulatory requirements for commercial and industrial applications.
