ISC1210EB3R3J Equivalent & Substitute Parts

Part Overview

The ISC1210EB3R3J is a 3.3 µH shielded drum core wirewound inductor manufactured by Vishay Dale, designed for surface mount applications in the 1210 (3225 Metric) package. This component operates at 270 mA maximum current with 1.1 Ohm maximum DC resistance and maintains active product status. Substitute parts become necessary when addressing supply chain constraints, packaging format requirements, or specific thermal operating range needs while maintaining electrical and mechanical compatibility within the 1210 package footprint.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ISC1210EB3R3J is determined by the following critical parameters:

• Inductance Value: 3.3 µH (exact match required)
• Tolerance: ±5% (exact match required)
• Package / Case: 1210 (3225 Metric) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Current Rating: Minimum 260 mA acceptable (substitute may operate at lower current than primary part)
• DC Resistance: Up to 1.2 Ohm acceptable (substitute may have slightly higher resistance)
• Operating Temperature Range: Substitute must support minimum -40°C ~ 105°C
• RoHS Compliance: ROHS3 Compliant (required)

The substitute parts NLV32T-3R3J-EF and NLV32T-3R3J-PF meet these criteria despite differences in core material (ferrite vs. iron powder) and shielding configuration (unshielded vs. shielded), as these variations remain within acceptable electrical performance parameters for the specified inductance and frequency characteristics.

Parameter Comparison

Engineering Selection Recommendations

ISC1210EB3R3J (Primary Part): Select this part for applications requiring extended operating temperature range (-55°C ~ 125°C), shielded core construction, or when iron powder core characteristics are specified. Product status is Active, ensuring long-term availability and continued manufacturing support.

NLV32T-3R3J-EF (Substitute - Recommended): This TDK part is suitable for applications operating within -40°C ~ 105°C temperature range and tolerating unshielded ferrite core construction. Product status is Active. Packaging format is Tape & Reel (TR), appropriate for automated assembly processes. REACH status is Affected; verify compliance requirements for your application jurisdiction.

NLV32T-3R3J-PF (Substitute - Legacy): This TDK part carries "Not For New Designs" product status and should be used only for replacement or maintenance of existing assemblies. Packaging format is Cut Tape (CT) & Digi-Reel®. REACH status is Affected. Avoid selection for new product development.

Frequently Asked Questions (FAQ)

Q: Can NLV32T-3R3J-EF or NLV32T-3R3J-PF be used as direct replacements for ISC1210EB3R3J?

A: Both TDK parts meet the core electrical specifications (3.3 µH inductance, ±5% tolerance, 1210 package, surface mount) and maintain equivalent Q factor and self-resonant frequency. However, the operating temperature range is narrower (-40°C ~ 105°C vs. -55°C ~ 125°C), and the core material differs (ferrite vs. iron powder). Substitution is valid only if your application operates within the TDK temperature range and does not require shielded core characteristics.

Q: What is the difference between shielded and unshielded configurations?

A: The ISC1210EB3R3J features a shielded drum core (iron powder), while NLV32T-3R3J-EF and NLV32T-3R3J-PF use unshielded ferrite cores. Shielding reduces electromagnetic interference emission and susceptibility. Select shielded parts for noise-sensitive applications; unshielded parts are acceptable for general-purpose filtering and impedance matching.

Q: Why do the substitute parts have lower current ratings (260 mA vs. 270 mA)?

A: The 10 mA difference reflects different core material saturation characteristics and thermal design margins between manufacturers. If your circuit operates below 260 mA, this difference is not limiting. If your design requires the full 270 mA rating, the ISC1210EB3R3J is the appropriate selection.

Q: What is the significance of "Not For New Designs" status on NLV32T-3R3J-PF?

A: This designation indicates TDK is transitioning this part to end-of-life. While current inventory exists, future availability is not guaranteed. For new product development, select NLV32T-3R3J-EF (Active status) or ISC1210EB3R3J.

Q: Are there packaging format differences between the substitute parts?

A: Yes. NLV32T-3R3J-EF is supplied in Tape & Reel (TR) format, standard for high-volume automated assembly. NLV32T-3R3J-PF is supplied in Cut Tape (CT) & Digi-Reel® format, suitable for lower-volume or manual assembly processes. Verify your assembly equipment compatibility before selection.

Q: How do the DC resistance values affect circuit performance?

A: ISC1210EB3R3J specifies 1.1 Ohm maximum; substitutes specify 1.2 Ohm maximum. This 0.1 Ohm difference increases power dissipation by approximately 9% at rated current. For applications with tight thermal budgets or high current density, measure actual resistance values before substitution.
