ISC1210BN6R8J Equivalent & Substitute Parts

Part Overview

The ISC1210BN6R8J is a 6.8 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 205 mA maximum current with 1.6Ohm maximum DC resistance and is rated for -55°C to 125°C operating temperature. The part is currently active in production. Equivalent and substitute parts are identified when design requirements necessitate alternative sourcing, compliance updates, or inventory availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ISC1210BN6R8J is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 6.8 µH with ±5% tolerance
• Package form factor: 1210 (3225 Metric) surface mount
• Q factor at test frequency: 30 @ 7.96MHz
• Self resonant frequency: 40MHz

Secondary Compatibility Parameters:

• Current rating must meet or exceed 205 mA minimum requirement
• DC resistance must not exceed 1.6Ohm maximum
• Operating temperature range must encompass application requirements
• Mounting type: Surface mount

The identified substitute NLV32T-6R8J-PF meets the primary inductance, package, and frequency specifications. Variations in core material (ferrite vs. iron powder), shielding configuration (unshielded vs. shielded), current rating (180 mA vs. 205 mA), and DC resistance (1.8Ohm vs. 1.6Ohm) represent trade-offs that must be evaluated against specific circuit requirements.

Parameter Comparison

Engineering Selection Recommendations

ISC1210BN6R8J (Primary Selection): The ISC1210BN6R8J remains the preferred choice for applications requiring the full 205 mA current rating, extended temperature range (-55°C to 125°C), and shielded configuration. This part is active in production and suitable for new designs. RoHS non-compliance must be evaluated against application regulatory requirements.

NLV32T-6R8J-PF (Substitute Consideration): The NLV32T-6R8J-PF is designated "Not For New Designs" and should be used only for legacy system support or when ROHS3 compliance is mandatory. This substitute is applicable only when circuit current requirements do not exceed 180 mA and operating temperature range remains within -40°C to 105°C. The unshielded configuration and ferrite core material may introduce different EMI characteristics compared to the shielded iron powder core of the main part.

Frequently Asked Questions (FAQ)

Q: Can NLV32T-6R8J-PF be used as a direct replacement in all applications?

A: No. The substitute has a lower current rating (180 mA vs. 205 mA) and narrower operating temperature range (-40°C to 105°C vs. -55°C to 125°C). Use only when circuit requirements fall within these reduced specifications.

Q: What is the impact of switching from shielded to unshielded core?

A: The unshielded ferrite core of the substitute may exhibit different electromagnetic coupling and EMI performance compared to the shielded iron powder core of the main part. Circuit-level EMI testing is necessary if shielding was specified for noise mitigation.

Q: Does the higher DC resistance of the substitute affect circuit performance?

A: The substitute has 1.8Ohm maximum DC resistance versus 1.6Ohm for the main part. This 0.2Ohm increase results in higher resistive losses and heat dissipation. Thermal and efficiency analysis is required for current-sensitive applications.

Q: Why is NLV32T-6R8J-PF marked "Not For New Designs"?

A: This designation indicates the manufacturer has discontinued active development and recommends alternative parts for new product development. Use is limited to legacy system maintenance and repair.

Q: Are both parts available in the same packaging format?

A: Yes. Both parts use 1210 (3225 Metric) surface mount package with identical footprint dimensions (0.126" L x 0.098" W / 3.20mm x 2.49mm). PCB layout compatibility is maintained.
