ISC1210ER3R3J Equivalent & Substitute Parts

Part Overview

The ISC1210ER3R3J 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 performance within acceptable tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ISC1210ER3R3J is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Inductance value: 3.3 µH (±5% tolerance maintained)
• Current rating: minimum 260 mA (substitute parts rated at 260 mA are acceptable for applications not requiring the full 270 mA specification)
• DC resistance: maximum 1.2 Ohm (0.1 Ohm variance acceptable within circuit design margins)
• Q factor and self-resonant frequency: 30 @ 7.96 MHz and 60 MHz respectively

Mechanical & Package Compatibility:

• Package format: 1210 (3225 Metric) surface mount
• Physical dimensions: 0.126" L x 0.098" W (3.20mm x 2.49mm nominal)
• Height seated: maximum 0.095" (2.41mm)

Environmental & Compliance Parameters:

• Operating temperature range: -40°C ~ 105°C (narrower than main part but acceptable for most applications)
• RoHS3 compliance required
• Moisture sensitivity level: 1 (Unlimited)

Packaging Format Variations:

• Tape & Reel (TR) primary format
• Cut Tape (CT) & Digi-Reel® alternative format

The substitute parts NLV32T-3R3J-EF and NLV32T-3R3J-PF meet all electrical parameters within acceptable engineering tolerances. The primary difference is core material (ferrite vs. iron powder) and shielding configuration, which do not affect substitutability for this inductance value and frequency range.

Parameter Comparison

Engineering Selection Recommendations

NLV32T-3R3J-EF (Primary Substitute)

This part is the preferred substitute for the ISC1210ER3R3J. It maintains active product status and meets all electrical specifications within acceptable tolerances. The 10 mA reduction in current rating (260 mA vs. 270 mA) is acceptable for applications operating below 260 mA. The 0.1 Ohm increase in maximum DC resistance falls within standard circuit design margins. Tape & Reel packaging ensures compatibility with standard assembly processes. RoHS3 compliance and unlimited moisture sensitivity level match the main part requirements.

NLV32T-3R3J-PF (Secondary Substitute)

This part is electrically equivalent to NLV32T-3R3J-EF but carries "Not For New Designs" product status. It is suitable only for legacy system maintenance, repair, or continuation of existing production runs. The Cut Tape & Digi-Reel® packaging format may require process adjustments in automated assembly environments. Selection of this part should be limited to applications where design continuity with existing inventory is required.

Operating Temperature Consideration

Both substitute parts operate within -40°C ~ 105°C, which is narrower than the main part's -55°C ~ 125°C range. Applications requiring operation below -40°C or above 105°C must retain the ISC1210ER3R3J.

Frequently Asked Questions (FAQ)

Q: Can NLV32T-3R3J-EF replace ISC1210ER3R3J in all applications?

A: NLV32T-3R3J-EF is electrically compatible for applications where circuit current does not exceed 260 mA and operating temperature remains within -40°C ~ 105°C. Applications requiring the full 270 mA rating or extended temperature range (-55°C) must use the ISC1210ER3R3J.

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

A: The ISC1210ER3R3J uses a shielded iron powder core, while NLV32T-3R3J-EF and NLV32T-3R3J-PF use unshielded ferrite cores. Both configurations maintain identical inductance and Q factor specifications at 7.96 MHz. Shielding reduces electromagnetic interference emission; unshielded designs may be suitable for applications with lower EMI sensitivity requirements.

Q: Are there packaging format restrictions?

A: NLV32T-3R3J-EF is supplied in Tape & Reel (TR) format, compatible with standard pick-and-place assembly equipment. NLV32T-3R3J-PF uses Cut Tape (CT) & Digi-Reel® format, which may require manual handling or specialized feeder compatibility. Verify assembly equipment compatibility before selecting the Cut Tape format.

Q: Why is NLV32T-3R3J-PF marked "Not For New Designs"?

A: This designation indicates the part is in mature or declining production phase. It remains available for existing applications but should not be selected for new product development. NLV32T-3R3J-EF is the recommended choice for new designs.

Q: What is the impact of the 0.1 Ohm DC resistance increase?

A: The increase from 1.1 Ohm to 1.2 Ohm maximum represents approximately 9% higher resistive loss. For most applications, this variance is absorbed within circuit design margins. High-current or precision applications should evaluate power dissipation impact using actual measured values.

Q: Do all parts meet RoHS3 compliance?

A: Yes. ISC1210ER3R3J, NLV32T-3R3J-EF, and NLV32T-3R3J-PF are all ROHS3 compliant with unlimited moisture sensitivity level (MSL 1), ensuring compatibility with standard manufacturing and storage requirements.
