Part Overview

The ISC1210EB1R5J is a 1.5 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 370 mA current rating with a maximum DC resistance of 750mOhm and is rated for operating temperatures from -55°C to 125°C. The part is currently active and ROHS3 compliant. Equivalent and substitute parts are identified based on matching electrical specifications including inductance value, current rating, tolerance, and mechanical compatibility within the 1210 package footprint.

Substitute Part Grouping Explanation

Substitute parts for the ISC1210EB1R5J are qualified based on the following electrical and mechanical parameters:

Inductance value: 1.5 µH (exact match required)
Tolerance: ±5% (exact match required)
Current rating: 370 mA (exact match required)
Package / Case: 1210 (3225 Metric) (exact match required)
Mounting type: Surface Mount (exact match required)
DC Resistance: Maximum 850mOhm (allowable variance from 750mOhm specification)

The substitute parts identified are from TDK Corporation's NLV series. These parts maintain electrical equivalence in inductance, tolerance, and current handling capability while operating within the same physical footprint. Differences in core material (ferrite vs. iron powder), shielding configuration, and operating temperature range are noted as design trade-offs that may affect circuit performance in specific applications.

Engineering Selection Recommendations

NLV32T-1R5J-EF and NLV32T-1R5J-EFD are both active products suitable for new designs. NLV32T-1R5J-EFD carries AEC-Q200 automotive qualification, making it appropriate for applications requiring automotive-grade reliability. NLV32T-1R5J-PF is marked as "Not For New Designs" and should be avoided in new development projects.

All substitute parts are ROHS3 compliant. The primary electrical differences are increased DC resistance (850mOhm vs. 750mOhm) and reduced self-resonant frequency (85MHz vs. 90MHz). The operating temperature range of substitute parts is narrower (-40°C to 105°C vs. -55°C to 125°C). Substitute parts use ferrite core material and are unshielded, contrasting with the shielded iron powder core of the original part.

Frequently Asked Questions (FAQ)

Q: Can NLV32T-1R5J-EF, NLV32T-1R5J-EFD, and NLV32T-1R5J-PF be used interchangeably with ISC1210EB1R5J?

A: These parts share identical inductance (1.5 µH), tolerance (±5%), current rating (370 mA), and package footprint (1210). They are electrically equivalent for basic inductance function. However, differences in DC resistance, core material, shielding, and operating temperature range may affect performance in specific circuit applications. Circuit validation is necessary to confirm suitability.

Q: What are the key differences between the substitute parts?

A: NLV32T-1R5J-EF and NLV32T-1R5J-EFD are functionally identical; the primary distinction is that NLV32T-1R5J-EFD includes AEC-Q200 automotive qualification. NLV32T-1R5J-PF is functionally similar but is designated "Not For New Designs" and should not be selected for new development.

Q: Why does the ISC1210EB1R5J have lower DC resistance than the TDK substitutes?

A: The ISC1210EB1R5J uses an iron powder core with shielding, while the TDK NLV series uses ferrite cores without shielding. These design differences result in different resistance characteristics. The 100mOhm difference (750mOhm vs. 850mOhm) may impact power dissipation in high-current applications.

Q: Are the substitute parts suitable for extended temperature range applications?

A: The ISC1210EB1R5J operates from -55°C to 125°C, while all TDK substitutes operate from -40°C to 105°C. If your application requires operation below -40°C or above 105°C, the ISC1210EB1R5J is the appropriate choice.

Q: Does the shielding difference affect circuit performance?

A: The ISC1210EB1R5J is shielded while the TDK substitutes are unshielded. Shielding reduces electromagnetic interference emission and susceptibility. In noise-sensitive circuits, the shielded design may provide superior performance. Unshielded designs are suitable for applications where EMI is not a primary concern.
