Equivalent & Substitute Parts for AISC-1812H-1R5N-T

Part Overview

The Abracon LLC AISC-1812H-1R5N-T is a fixed inductor with a 1.5 µH inductance, 1 A current rating, and 90 mOhm maximum DC resistance, housed in a surface mount 1812 (4532 Metric) package. The component features an unshielded drum core wirewound ferrite construction and is rated for operation between -25°C to 85°C. This part is classified as obsolete, making it necessary to identify direct substitute models with identical or stricter key parameters to ensure electrical and mechanical compatibility for ongoing designs or replacement inventory.

Key Parameters

Substitute Part Grouping Explanation

Substitution is established exclusively on key electrical and mechanical parameters: inductance, tolerance, current rating, DC resistance (DCR), drum core wirewound ferrite construction, unshielded design, identical surface mount 1812 (4532 Metric) package, and matching physical size. Compliance status (RoHS, MSL, REACH) and matching or stricter operating temperature ranges are also required for substitution.

Key parameters for equivalence:

• Inductance: 1.5 µH
• Tolerance: up to ±30%
• Current Rating: 1 A minimum
• DC Resistance: 90 mOhm maximum
• Surface Mount Type, 1812 package, identical dimensions
• Unshielded drum core, ferrite-based wirewound construction
• RoHS, MSL, REACH compliance
• Operating Temperature: within or exceeding -25°C ~ 85°C

Only substitute parts verified with these matched values are included.

Parameter Comparison

Engineering Selection Recommendations

Both AISC-1812H-1R5N-T and the substitute LQH43CN1R5M03L are ROHS3 compliant, have an MSL of 1 (Unlimited), and hold REACH Unaffected status. AISC-1812H-1R5N-T is obsolete. LQH43CN1R5M03L is discontinued at Digi-Key, but retains specification conformance. Selection is determined strictly by supplied certification and compliance information in conjunction with parameter equivalence.

Frequently Asked Questions (FAQ)

Q1: What parameters must match to substitute AISC-1812H-1R5N-T?
A1: Inductance, tolerance, current rating, DC resistance, package/case size, mounting type, core type, shielding, and compliance statuses must match.

Q2: Is the LQH43CN1R5M03L an identical drop-in replacement?
A2: LQH43CN1R5M03L matches all specified key parameters, including package and compliance statuses, qualifying it as a direct substitute based on provided data.

Q3: Are there differences in package mounting or dimensions?
A3: No differences; both parts share the 1812 (4532 Metric) package and identical physical dimensions.

Q4: Does tolerance variation affect substitution?
A4: LQH43CN1R5M03L provides a tighter tolerance (±20%) compared to the main part’s ±30%, which is compatible within the specified criteria.

Q5: Are there differences in environmental compliance?
A5: Both parts are ROHS3 compliant, with MSL 1 (Unlimited) and REACH Unaffected status.

Q6: What is the importance of the product status in substitution?
A6: AISC-1812H-1R5N-T is obsolete, necessitating substitutes for continued design and maintenance; LQH43CN1R5M03L is discontinued at one distributor but matches required specifications.
