ISC1210SY6R8J Equivalent & Substitute Parts

Part Overview

The ISC1210SY6R8J 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. Substitute parts may be required due to inventory availability, packaging format preferences, or design revision requirements while maintaining equivalent electrical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ISC1210SY6R8J is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 6.8 µH ±5%
• Package type: 1210 (3225 Metric) surface mount
• Mounting type: Surface mount
• Frequency test point: 7.96 MHz

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 the application requirements
• Self resonant frequency: 40MHz

The identified substitute NLV32T-6R8J-PF meets the primary matching criteria with equivalent inductance, package, and frequency characteristics. Differences 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

The NLV32T-6R8J-PF presents a viable substitute for the ISC1210SY6R8J when circuit current requirements do not exceed 180 mA. The substitute maintains equivalent inductance, tolerance, Q factor, and self resonant frequency specifications. However, the following factors require evaluation:

Compliance Considerations: The NLV32T-6R8J-PF is ROHS3 compliant, whereas the ISC1210SY6R8J is RoHS non-compliant. This distinction is significant for applications subject to RoHS regulations.

Product Status: The substitute is designated "Not For New Designs," indicating TDK Corporation does not recommend this part for new product development. The main part ISC1210SY6R8J maintains active production status.

Thermal Operating Range: The main part supports -55°C to 125°C operation, while the substitute operates within -40°C to 105°C. Applications requiring extended low-temperature performance below -40°C or high-temperature operation above 105°C are incompatible with the substitute.

Current Margin: The 25 mA reduction in current rating (205 mA to 180 mA) requires confirmation that circuit peak and RMS current demands remain within the substitute's specification.

Electromagnetic Characteristics: The transition from shielded iron powder core to unshielded ferrite core may alter EMI performance and frequency response in sensitive applications.

Frequently Asked Questions (FAQ)

Q: Can NLV32T-6R8J-PF be used as a direct replacement for ISC1210SY6R8J?

A: Substitution is possible only when circuit current requirements do not exceed 180 mA, operating temperature remains within -40°C to 105°C, and EMI shielding is not critical to circuit function. The unshielded ferrite core may introduce different coupling characteristics compared to the shielded iron powder core.

Q: What is the significance of the shielding difference?

A: The ISC1210SY6R8J features shielding that reduces electromagnetic radiation and susceptibility to external fields. The NLV32T-6R8J-PF is unshielded, which may increase EMI emissions and susceptibility in high-frequency or noise-sensitive applications.

Q: Why does the substitute have a lower current rating?

A: The NLV32T-6R8J-PF is rated for 180 mA maximum current versus 205 mA for the main part. This reflects differences in core material (ferrite vs. iron powder) and thermal design. Applications operating near the 205 mA limit cannot use the substitute without risk of exceeding its current specification.

Q: Are the packages physically identical?

A: Both parts use the 1210 (3225 Metric) package with identical length (0.126" / 3.20mm) and width (0.098" / 3.20mm or 2.50mm). Height differs slightly: ISC1210SY6R8J maximum 0.095" (2.41mm) versus NLV32T-6R8J-PF maximum 0.094" (2.40mm). This 0.01mm difference is negligible for standard PCB assembly.

Q: What is the impact of the RoHS compliance difference?

A: The NLV32T-6R8J-PF is ROHS3 compliant, while the ISC1210SY6R8J is RoHS non-compliant. For applications subject to RoHS regulations or customer requirements, the substitute provides compliance advantage. For unrestricted applications, this difference is not a technical constraint.

Q: Can the substitute be used in new product designs?

A: The NLV32T-6R8J-PF carries "Not For New Designs" status from TDK Corporation. While technically functional as a substitute, this designation indicates the manufacturer does not support this part for new development. The ISC1210SY6R8J (Active status) is the preferred choice for new designs.

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

A: The ISC1210SY6R8J specifies 1.6Ohm maximum DC resistance, while the NLV32T-6R8J-PF specifies 1.8Ohm maximum. The 0.2Ohm difference increases power dissipation and may affect circuit Q factor and efficiency. In low-current or high-impedance circuits, this difference is typically negligible. In high-current applications, the additional resistance generates measurable heat.
