ISC1210EB4R7J Equivalent & Substitute Parts

Part Overview

The ISC1210EB4R7J is a 4.7 µH shielded drum core wirewound inductor manufactured by Vishay Dale, rated for 220 mA continuous current with a maximum DC resistance of 1.25Ohm. This surface mount component operates across the industrial temperature range of -55°C to 125°C and is designed for applications requiring electromagnetic shielding in compact 1210 (3225 Metric) form factor packages.

The part is currently in active production status. Substitute parts are identified when equivalent electrical performance can be maintained across critical parameters including inductance value, current rating, frequency characteristics, and physical dimensions, while accounting for differences in core material, shielding configuration, and operating temperature ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ISC1210EB4R7J are qualified based on the following critical parameters:

Electrical Equivalence Criteria:

• Inductance value: 4.7 µH (±5% tolerance maintained)
• Current rating: 220 mA minimum
• Q factor: 30 @ 7.96MHz
• Inductance test frequency: 7.96 MHz
• Package / Case: 1210 (3225 Metric)
• Mounting type: Surface Mount

Acceptable Variations:

• DC resistance: Substitute parts may have higher maximum DCR (1.5Ohm vs. 1.25Ohm) provided circuit design accommodates increased resistive losses
• Core material: Ferrite core substitutes are acceptable where shielding requirements can be met through circuit layout or external shielding
• Operating temperature: Substitute parts with narrower temperature ranges (-40°C ~ 105°C) are acceptable for applications not requiring full -55°C ~ 125°C coverage
• Self resonant frequency: Minor variations (50MHz vs. 52MHz) remain within acceptable operating margins

The identified substitutes NLV32T-4R7J-EF and NLV32T-4R7J-EFD from TDK Corporation meet these electrical equivalence criteria while differing in core shielding configuration and temperature operating range.

Parameter Comparison

Engineering Selection Recommendations

ISC1210EB4R7J (Primary Part):

• Shielded iron powder core construction provides electromagnetic interference mitigation
• Extended operating temperature range (-55°C ~ 125°C) supports automotive and industrial applications
• Lower DC resistance (1.25Ohm max) minimizes resistive losses in current-limited circuits
• Active production status with established supply chain

NLV32T-4R7J-EF (TDK Substitute):

• Unshielded ferrite core design reduces component cost and footprint
• Standard commercial temperature range (-40°C ~ 105°C) suitable for consumer and industrial applications
• Higher DC resistance (1.5Ohm max) requires circuit design verification for power dissipation tolerance
• ROHS3 compliant with unlimited moisture sensitivity rating
• Tape & Reel packaging supports high-volume manufacturing

NLV32T-4R7J-EFD (TDK Substitute with AEC-Q200):

• Identical electrical specifications to NLV32T-4R7J-EF
• AEC-Q200 automotive qualification provides additional reliability assurance for automotive applications
• Unshielded ferrite core configuration
• Tape & Reel packaging
• Recommended for automotive and mission-critical applications requiring automotive-grade component certification

Frequently Asked Questions (FAQ)

Q: Can NLV32T-4R7J-EF or NLV32T-4R7J-EFD replace ISC1210EB4R7J in all applications?

A: Electrical substitution is valid for inductance, current rating, and frequency response. However, the unshielded ferrite core differs from the shielded iron powder core. Applications requiring electromagnetic shielding must evaluate whether external shielding or circuit layout modifications can compensate for the loss of integrated shielding.

Q: What is the impact of increased DC resistance in the TDK substitutes?

A: The TDK parts specify 1.5Ohm maximum DCR compared to 1.25Ohm for the ISC1210EB4R7J. This 0.25Ohm increase results in higher resistive losses. At 220 mA, this represents approximately 60 mW additional power dissipation. Circuit designs must accommodate this increased loss or operate at reduced current levels.

Q: Are the TDK substitutes suitable for extended temperature applications?

A: The TDK substitutes operate from -40°C to 105°C, which is narrower than the ISC1210EB4R7J range of -55°C to 125°C. Applications requiring operation below -40°C or above 105°C must use the original ISC1210EB4R7J or identify alternative parts with extended temperature ratings.

Q: What is the difference between NLV32T-4R7J-EF and NLV32T-4R7J-EFD?

A: Both parts are electrically identical with matching inductance, current rating, and frequency characteristics. The primary difference is that NLV32T-4R7J-EFD carries AEC-Q200 automotive qualification, making it suitable for automotive applications requiring automotive-grade component certification. The NLV32T-4R7J-EF is the standard commercial version.

Q: Are physical dimensions compatible between the main part and substitutes?

A: All three parts use the 1210 (3225 Metric) package with identical length and width (0.126" L x 0.098" W / 3.20mm x 2.49mm to 2.50mm). Height differences are negligible (0.095" vs. 0.094" seated height), ensuring PCB layout compatibility.

Q: What packaging formats are available?

A: The ISC1210EB4R7J is supplied in Bulk packaging. The TDK substitutes (NLV32T-4R7J-EF and NLV32T-4R7J-EFD) are supplied in Tape & Reel (TR) format, which is standard for high-volume surface mount assembly operations.
