ASPI-2012-2R2M-T Equivalent & Substitute Parts

Part Overview

The ASPI-2012-2R2M-T is a 2.2 µH shielded drum core wirewound inductor manufactured by Abracon LLC, designed for surface mount applications in the 2.00mm x 2.00mm nonstandard package format. This component is rated for 1.2 A continuous current with a maximum DC resistance of 127mOhm and operates across the -40°C to 125°C temperature range. The part maintains Active product status and is ROHS3 compliant with unlimited moisture sensitivity rating.

Substitute parts become necessary when the primary component experiences supply constraints, extended lead times, or when design requirements permit operation within the electrical and mechanical tolerances of alternative manufacturers' offerings.

Substitute Part Grouping Explanation

The VLS2012ET-2R2M from TDK Corporation qualifies as a substitute based on the following alignment of critical electrical and mechanical parameters:

Matching Parameters:

• Inductance value: 2.2 µH with ±20% tolerance
• Inductance test frequency: 1 MHz
• Shielding: Shielded construction
• Package footprint: 2.00mm x 2.00mm
• Height - Seated (Max): 1.20mm
• Mounting type: Surface Mount
• RoHS Status: ROHS3 Compliant
• MSL Rating: 1 (Unlimited)
• Packaging: Tape & Reel (TR)

Variance Parameters:

• Current Rating: 1.0 A (substitute) versus 1.2 A (main part)
• Current - Saturation (Isat): 1.0 A (substitute) versus 1.4 A (main part)
• DC Resistance (DCR): 153mOhm Max (substitute) versus 127mOhm Max (main part)
• Operating Temperature Range: -40°C to 105°C (substitute) versus -40°C to 125°C (main part)

The substitute part operates within the same inductance specification and physical envelope. Variance in current ratings, saturation current, and DC resistance must be evaluated against specific circuit requirements.

Parameter Comparison

Engineering Selection Recommendations

The ASPI-2012-2R2M-T maintains Active product status and is recommended for new designs. The VLS2012ET-2R2M carries a "Not For New Designs" designation and should be considered only for legacy system support or when supply of the primary part is unavailable.

Selection between these parts depends on circuit-level current requirements. The ASPI-2012-2R2M-T supports higher continuous current (1.2 A) and saturation current (1.4 A) with lower DC resistance (127mOhm Max). The VLS2012ET-2R2M is rated for 1.0 A continuous current with 1.0 A saturation current and 153mOhm Max DC resistance.

Both parts meet ROHS3 compliance and unlimited moisture sensitivity requirements. The ASPI-2012-2R2M-T operates to 125°C maximum, while the VLS2012ET-2R2M is limited to 105°C. Applications requiring operation above 105°C must use the primary part.

Frequently Asked Questions (FAQ)

Q: Can VLS2012ET-2R2M replace ASPI-2012-2R2M-T in all applications?

A: Substitution is valid only when circuit current requirements do not exceed 1.0 A continuous and 1.0 A saturation, and when maximum operating temperature does not exceed 105°C. The higher DC resistance of the substitute part (153mOhm versus 127mOhm) results in increased power dissipation and must be evaluated for thermal impact.

Q: What is the significance of the "Not For New Designs" status on the TDK part?

A: This designation indicates the manufacturer does not recommend the VLS2012ET-2R2M for new product development. It may have limited future availability or ongoing support. New designs should prioritize the ASPI-2012-2R2M-T.

Q: Are the physical packages identical?

A: Both parts share identical footprint dimensions (2.00mm x 2.00mm) and seated height (1.20mm maximum). Both are surface mount components in nonstandard package format with Tape & Reel packaging. PCB layout compatibility is confirmed.

Q: How do the inductance tolerances compare?

A: Both parts specify ±20% inductance tolerance at 1 MHz test frequency. Inductance matching between the two parts is equivalent within this tolerance band.

Q: What compliance certifications apply to both parts?

A: Both the ASPI-2012-2R2M-T and VLS2012ET-2R2M are ROHS3 compliant, REACH unaffected, and carry MSL rating 1 (unlimited moisture sensitivity). Both are classified under ECCN EAR99.
