ISC1210BN5R6J Equivalent & Substitute Parts

Part Overview

The ISC1210BN5R6J is a 5.6 µH shielded drum core wirewound inductor manufactured by Vishay Dale, designed for surface mount applications in the 1210 (3225 Metric) package. This component operates across an industrial temperature range of -55°C to 125°C with a maximum DC resistance of 1.4Ohm and supports a current rating of 210 mA. The part is currently active in production and available in bulk packaging with 674 pieces in stock.

Substitute parts are necessary when the original component becomes unavailable, when alternative compliance certifications are required, or when design revisions call for different core material properties or packaging formats while maintaining equivalent electrical performance.

Substitute Part Grouping Explanation

Substitution eligibility for the ISC1210BN5R6J is determined by the following critical parameters:

Inductance Value: Must be 5.6 µH with ±5% tolerance
Package Footprint: Must be 1210 (3225 Metric) surface mount
Current Rating: Substitute must support minimum 200 mA (acceptable tolerance below the original 210 mA specification)
DC Resistance: Substitute DCR up to 1.6Ohm is acceptable within circuit design margins
Core Material: Iron powder or ferrite core materials are both acceptable for this inductance value
Shielding: Both shielded and unshielded variants are functionally equivalent for this application category
Frequency Characteristics: Q factor and self-resonant frequency must remain within acceptable operating ranges

The substitute parts NLV32T-5R6J-EF and NLV32T-5R6J-PF meet these substitution criteria despite differences in core material (ferrite vs. iron powder) and shielding configuration.

Engineering Selection Recommendations

NLV32T-5R6J-EF is the primary recommended substitute for new designs and ongoing production. This part maintains active product status with TDK Corporation and achieves ROHS3 compliance, addressing regulatory requirements that the original ISC1210BN5R6J does not meet. The ferrite core construction and unshielded design provide equivalent electrical performance within the specified tolerance bands. The 200 mA current rating is acceptable for applications designed within the 210 mA specification margin. Operating temperature range is reduced to -40°C ~ 105°C, which is suitable for commercial and industrial applications outside extreme low-temperature environments.

NLV32T-5R6J-PF is functionally equivalent to NLV32T-5R6J-EF but carries a "Not For New Designs" status. This part should be used only for legacy system maintenance or when existing inventory constraints require its use. Both TDK variants offer superior compliance posture compared to the original Vishay Dale component.

Frequently Asked Questions (FAQ)

Q: Can NLV32T-5R6J-EF and NLV32T-5R6J-PF be used interchangeably with ISC1210BN5R6J?

A: Yes, both TDK parts are electrically equivalent substitutes. They maintain the same 5.6 µH inductance, ±5% tolerance, and identical package footprint. The 10 mA reduction in current rating (200 mA vs. 210 mA) and 0.2Ohm increase in maximum DC resistance fall within acceptable design margins for most applications. For new designs, NLV32T-5R6J-EF is preferred due to active product status.

Q: What is the impact of switching from shielded (ISC1210BN5R6J) to unshielded (NLV32T-5R6J series) inductors?

A: Unshielded inductors exhibit greater magnetic field radiation. In applications where electromagnetic interference (EMI) control is critical, circuit layout and spacing must be evaluated. For most general-purpose filtering and energy storage applications, the unshielded ferrite core design performs equivalently. Shielding requirements should be determined by system-level EMI testing rather than component selection alone.

Q: Are there temperature range limitations when substituting?

A: The substitute parts operate from -40°C to 105°C, compared to the original -55°C to 125°C range. Applications requiring operation below -40°C or above 105°C must retain the ISC1210BN5R6J or identify alternative components with extended temperature specifications.

Q: What are the compliance differences?

A: NLV32T-5R6J-EF and NLV32T-5R6J-PF are ROHS3 compliant, while ISC1210BN5R6J is RoHS non-compliant. All three parts are REACH Affected and carry EAR99 ECCN classification. For applications subject to RoHS directives, the TDK substitutes are required.

Q: How do core material differences affect circuit performance?

A: Iron powder cores (ISC1210BN5R6J) and ferrite cores (NLV32T-5R6J series) both achieve the specified 5.6 µH inductance and 30 Q factor at 7.96MHz. Ferrite cores typically exhibit lower core loss at higher frequencies, while iron powder cores provide broader temperature stability. For the specified operating frequency range, both materials deliver equivalent performance.
