ISC1210EB1R5K Equivalent & Substitute Parts

Part Overview

The ISC1210EB1R5K 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 actively produced. Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the specified parameter tolerances for this inductance value and current rating category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ISC1210EB1R5K is determined by the following critical parameters:

• Inductance Value: Must be 1.5 µH with ±10% tolerance
• Current Rating: Must support minimum 370 mA
• Package / Case: Must be 1210 (3225 Metric) surface mount
• DC Resistance: Must not exceed 750mOhm maximum
• Compliance: Must maintain ROHS3 compliance and EAR99 classification

The Würth Elektronik 744764015 qualifies as a substitute based on matching inductance, current rating, package dimensions, and compliance certifications. Differences in core material (ferrite vs. iron powder) and shielding configuration do not preclude substitution when electrical parameters remain within specification.

Engineering Selection Recommendations

Both the ISC1210EB1R5K and 744764015 maintain active product status and full compliance with ROHS3 and REACH regulations. Selection between these parts should be based on:

• DC Resistance Tolerance: The ISC1210EB1R5K specifies 750mOhm maximum, while the 744764015 specifies 850mOhm maximum. Applications with strict power dissipation requirements should prioritize the lower resistance specification.
• Operating Temperature Range: The ISC1210EB1R5K supports -55°C to 125°C, while the 744764015 supports -40°C to 105°C. High-temperature or low-temperature applications may require the Vishay Dale component.
• Packaging Format: The ISC1210EB1R5K is supplied in Bulk packaging, while the 744764015 is supplied in Tape & Reel format. Procurement and assembly processes should align with available packaging options.
• Regulatory Classification: Both components carry EAR99 classification and are suitable for equivalent export compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can the 744764015 be used as a direct replacement for the ISC1210EB1R5K?

A: The 744764015 is electrically compatible for applications requiring 1.5 µH inductance at 370 mA current rating in the 1210 package. The 100mOhm increase in maximum DC resistance and narrower operating temperature range must be evaluated against circuit requirements.

Q: What is the difference between shielded and unshielded configurations?

A: The ISC1210EB1R5K features shielding with an iron powder core, while the 744764015 is unshielded with a ferrite core. Shielding reduces electromagnetic interference coupling to adjacent components. Circuit layout and EMI sensitivity determine whether shielding is necessary.

Q: Are the physical dimensions identical?

A: Dimensions are nearly identical within manufacturing tolerance. The ISC1210EB1R5K measures 3.20mm x 2.49mm x 2.41mm (max height), while the 744764015 measures 3.20mm x 2.50mm x 2.40mm (max height). Both fit the 1210 (3225 Metric) footprint.

Q: Which part should be selected for high-temperature applications?

A: The ISC1210EB1R5K supports operation to 125°C, exceeding the 744764015 maximum of 105°C. For applications requiring the full -55°C to 125°C range, the ISC1210EB1R5K is the appropriate selection.

Q: What packaging formats are available?

A: The ISC1210EB1R5K is supplied in Bulk packaging, while the 744764015 is supplied in Tape & Reel format. Procurement specifications and assembly equipment compatibility should guide packaging selection.
