ASPI-2510-1R0N-T2 Equivalent & Substitute Parts

Part Overview

The ASPI-2510-1R0N-T2 is a 1 µH shielded drum core wirewound inductor manufactured by Abracon LLC, rated for 1.9 A continuous current with 70mOhm DC resistance in a compact 1008 (2520 Metric) surface mount package. This part is classified as obsolete, necessitating identification of active equivalent components that maintain functional compatibility within the same package footprint and electrical performance envelope.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ASPI-2510-1R0N-T2 is determined by the following critical parameters:

• Inductance Value: Must be 1 µH (exact match required)
• Package / Case: Must be 1008 (2520 Metric) for PCB footprint compatibility
• Shielding Type: Must be shielded to maintain electromagnetic isolation
• Core Material: Must be ferrite to preserve frequency response characteristics
• Mounting Type: Must be surface mount for assembly compatibility
• Operating Temperature Range: Must support -40°C ~ 125°C minimum
• Current Rating: Must meet or exceed 1.9 A requirement
• DC Resistance: Must not exceed 70mOhm to maintain power efficiency

The ASPI-2510-1R0M-T2 qualifies as a direct substitute based on these parameters, with allowable variations in tolerance and saturation current within the electrical performance envelope.

Parameter Comparison

Engineering Selection Recommendations

The ASPI-2510-1R0M-T2 is the recommended substitute for the obsolete ASPI-2510-1R0N-T2. Both components are manufactured by Abracon LLC and maintain identical package geometry, shielding configuration, and operating temperature specifications. The substitute part carries active product status, ensuring continued availability and supply chain reliability.

Compliance certifications are equivalent: both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. The substitute exhibits improved inductance tolerance (±20% versus ±30%), which enhances circuit performance predictability. The 1.8 A current rating of the substitute is marginally lower than the 1.9 A rating of the original part; however, the higher saturation current (2.05 A versus 1.75 A) provides superior headroom in transient conditions. The DC resistance increase from 70mOhm to 80mOhm maximum represents a 14% increase in power dissipation, which must be evaluated within the specific application thermal budget.

Frequently Asked Questions (FAQ)

Q: Can the ASPI-2510-1R0M-T2 be used as a direct replacement for the ASPI-2510-1R0N-T2 on existing PCBs?

A: Yes. Both parts share identical package dimensions (1008 / 2520 Metric), footprint, and mounting type. No PCB redesign is required.

Q: What is the significance of the current rating difference (1.9 A vs. 1.8 A)?

A: The substitute part has a 0.1 A lower continuous current rating. Applications operating at or above 1.8 A must verify that the substitute's saturation current (2.05 A) and thermal characteristics remain acceptable for the intended duty cycle.

Q: How does the DC resistance increase from 70mOhm to 80mOhm affect circuit performance?

A: The 10mOhm increase results in approximately 14% higher resistive losses. At 1.9 A, this represents an additional 36 mW of power dissipation. Thermal analysis of the application is required to confirm acceptability.

Q: Are there compliance or regulatory differences between these parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical ECCN and HTSUS classifications.

Q: Why is the inductance tolerance tighter on the substitute part?

A: The ASPI-2510-1R0M-T2 specifies ±20% tolerance compared to ±30% for the original. This represents improved manufacturing control and provides better circuit performance predictability.
