ISC1210ER6R8J Equivalent & Substitute Parts

Part Overview

The ISC1210ER6R8J 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 actively supported by the manufacturer. Finding equivalent or substitute parts becomes necessary when addressing supply chain constraints, design revisions, or specific application requirements that may benefit from alternative core materials or electrical characteristics within the same inductance and package specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the ISC1210ER6R8J is determined by the following critical parameters:

• Inductance Value: Must be 6.8 µH with ±5% tolerance
• Package / Case: Must be 1210 (3225 Metric) for mechanical and electrical compatibility
• Mounting Type: Must be Surface Mount
• Current Rating: Substitute must support minimum 205 mA operation
• DC Resistance: Substitute DCR must not exceed application thermal and efficiency requirements
• Core Material & Shielding: May vary (iron powder shielded vs. ferrite unshielded) based on EMI performance and frequency response needs
• Operating Temperature: Substitute range must encompass or exceed -55°C ~ 125°C for full compatibility
• RoHS & Compliance: Must maintain ROHS3 compliance for regulatory alignment

The substitute part NLV32T-6R8J-PF meets the core electrical and mechanical criteria but introduces variations in core material (ferrite vs. iron powder), shielding (unshielded vs. shielded), current rating (180 mA vs. 205 mA), and operating temperature range (-40°C ~ 105°C vs. -55°C ~ 125°C).

Parameter Comparison

Engineering Selection Recommendations

The ISC1210ER6R8J remains the preferred choice for new designs due to its Active product status, extended operating temperature range (-55°C ~ 125°C), higher current rating (205 mA), and shielded construction. The NLV32T-6R8J-PF substitute from TDK Corporation carries a "Not For New Designs" status, indicating manufacturer discontinuation trajectory and reduced long-term availability assurance.

Selection of NLV32T-6R8J-PF should be limited to legacy design support or supply chain contingency scenarios where the following conditions are met:

• Application current requirement does not exceed 180 mA
• Operating temperature range remains within -40°C ~ 105°C
• EMI performance requirements can tolerate unshielded ferrite core construction
• DC resistance increase from 1.6Ohm to 1.8Ohm does not compromise thermal or efficiency specifications
• Packaging format (Cut Tape vs. Tape & Reel) aligns with assembly process capabilities

Both parts maintain ROHS3 compliance and identical inductance, tolerance, and frequency characteristics at the test frequency of 7.96 MHz.

Frequently Asked Questions (FAQ)

Q: Can NLV32T-6R8J-PF be used as a direct drop-in replacement for ISC1210ER6R8J?

A: Mechanical compatibility is confirmed (identical 1210 package), but electrical performance differs. The substitute has lower current rating (180 mA vs. 205 mA), higher DC resistance (1.8Ohm vs. 1.6Ohm), narrower temperature range (-40°C ~ 105°C vs. -55°C ~ 125°C), and unshielded construction. Substitution is valid only when application parameters fall within these reduced specifications.

Q: What is the impact of switching from shielded (iron powder) to unshielded (ferrite) construction?

A: Shielded iron powder cores provide superior EMI containment and are preferred in noise-sensitive applications. Unshielded ferrite cores exhibit different frequency response characteristics and may introduce coupling effects in densely populated PCB layouts. Core material selection depends on specific circuit requirements and EMI performance criteria.

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

A: This designation indicates the manufacturer is transitioning away from this product line. While currently available, long-term supply continuity is not guaranteed. New designs should prioritize ISC1210ER6R8J or equivalent parts with Active status.

Q: Are there differences in packaging that affect assembly?

A: ISC1210ER6R8J is supplied in Tape & Reel (TR) format, while NLV32T-6R8J-PF is available in Cut Tape (CT) & Digi-Reel® format. Assembly equipment compatibility and tape specifications may differ; verify with your procurement and manufacturing teams.

Q: Do both parts meet the same compliance standards?

A: Both parts are ROHS3 compliant and carry identical ECCN (EAR99) and HTSUS (8504.50.8000) classifications. Moisture Sensitivity Level is 1 (Unlimited) for both, indicating no special handling requirements.
