Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SRU2016-101Y is determined by the following critical parameters:

• Inductance Value: Must be 100 µH (matched)
• Core Type & Shielding: Must be ferrite-based, shielded drum core construction
• Mounting: Must be surface mount compatible
• Current Handling: Substitute must support minimum 190 mA operation
• Temperature Range: Must cover -40°C to 125°C
• Compliance: Must maintain RoHS3 and REACH compliance status

The ASPI-3012S-101M-T from Abracon LLC meets these substitution criteria. While it exhibits improved electrical characteristics (higher current rating, lower DCR, tighter tolerance), it maintains functional equivalence within the specified parameter envelope.

Parameter Comparison

Engineering Selection Recommendations

The ASPI-3012S-101M-T is a direct functional substitute for the obsolete SRU2016-101Y. Both components are RoHS3 compliant and REACH unaffected, meeting regulatory requirements for current applications.

The substitute part offers superior electrical performance: 32% higher current rating (250 mA vs. 190 mA), 42% lower DC resistance (2.86Ohm vs. 4.9Ohm), and tighter inductance tolerance (±20% vs. ±30%). These improvements provide enhanced thermal performance and reduced power dissipation in the application circuit.

Physical dimensions differ slightly. The ASPI-3012S-101M-T is marginally larger in footprint (3.00mm vs. 2.80mm) but shorter in height (1.40mm vs. 1.80mm). PCB layout verification is necessary to confirm spatial compatibility within the target application.

The substitute part is currently in active production with confirmed inventory availability, ensuring long-term supply chain stability compared to the obsolete original part.

Frequently Asked Questions (FAQ)

Q: Can the ASPI-3012S-101M-T directly replace the SRU2016-101Y without circuit modification?

A: The substitute part maintains the same inductance value (100 µH), core type (ferrite shielded), and operating temperature range. However, the improved electrical characteristics (lower DCR, higher current rating) and dimensional differences require PCB layout verification to confirm mechanical fit and thermal performance alignment with the original design.

Q: What is the significance of the lower DC resistance in the substitute part?

A: The ASPI-3012S-101M-T exhibits 2.86Ohm DCR compared to 4.9Ohm in the original part. Lower DCR reduces resistive losses and heat generation during operation, improving overall circuit efficiency. This is a beneficial characteristic for applications sensitive to power dissipation.

Q: Are there packaging differences between these parts?

A: The SRU2016-101Y uses nonstandard packaging in tape & reel format. The ASPI-3012S-101M-T is supplied in tape & reel (TR) packaging. Both are surface mount components with similar handling requirements. Footprint dimensions differ slightly (2.80mm vs. 3.00mm length/width; 1.80mm vs. 1.40mm height), requiring PCB design verification.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the SRU2016-101Y and ASPI-3012S-101M-T are RoHS3 compliant, REACH unaffected, and carry MSL rating 1 (unlimited moisture sensitivity level). They share identical ECCN (EAR99) and HTSUS (8504.50.8000) classifications.

Q: What is the practical difference in inductance tolerance between ±30% and ±20%?

A: The ASPI-3012S-101M-T provides tighter tolerance control (±20% vs. ±30%), resulting in more consistent inductance values across production batches. For applications requiring precise inductance specifications, the substitute part offers improved predictability and reduced circuit performance variation.
