Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ISC1210SY1R5K are qualified based on the following electrical and mechanical parameters:

• Inductance value: 1.5 µH (matching specification)
• Inductance tolerance: ±10% (matching specification)
• Current rating: 370 mA (matching specification)
• Package / Case: 1210 (3225 Metric) (matching mechanical footprint)
• Mounting type: Surface Mount (matching assembly method)
• DC Resistance: Maximum allowable variance within component design limits

The substitute part 744764015 (Würth Elektronik WE-GF series) meets these core electrical and mechanical requirements. Differences in core material (ferrite vs. iron powder), shielding configuration, and operating temperature range represent design variations within the allowed parameter space for this inductance and current rating category.

Parameter Comparison

Engineering Selection Recommendations

The ISC1210SY1R5K (Vishay Dale) maintains active product status with RoHS non-compliant classification. The substitute part 744764015 (Würth Elektronik WE-GF series) is ROHS3 compliant and also maintains active product status.

Selection between these parts depends on application-specific requirements:

• The ISC1210SY1R5K provides shielded construction with lower maximum DC resistance (750mOhm) and extended low-temperature operation (-55°C minimum).
• The 744764015 provides unshielded construction with higher maximum DC resistance (850mOhm), higher self-resonant frequency (250MHz vs. 90MHz), and ROHS3 compliance with a narrower operating temperature range (-40°C minimum).

Both parts share identical inductance, tolerance, current rating, and package specifications. The choice between shielded and unshielded configurations, core material differences, and compliance requirements should be determined by circuit design constraints and regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can 744764015 directly replace ISC1210SY1R5K in all applications?

A: Both parts meet the core electrical specifications (1.5 µH inductance, 370 mA current rating, ±10% tolerance) and share the same 1210 (3225 Metric) surface mount package. However, differences in shielding (shielded vs. unshielded), core material (iron powder vs. ferrite), DC resistance (750mOhm vs. 850mOhm maximum), and operating temperature range (-55°C to 125°C vs. -40°C to 105°C) must be evaluated against specific circuit requirements.

Q: What is the impact of shielding differences?

A: The ISC1210SY1R5K features shielded construction, while 744764015 is unshielded. Shielding reduces electromagnetic interference coupling to surrounding circuits. Application requirements for EMI performance determine whether the unshielded substitute is acceptable.

Q: How do core material differences affect performance?

A: The ISC1210SY1R5K uses iron powder core material; 744764015 uses ferrite core material. These materials exhibit different frequency response characteristics, temperature coefficients, and saturation behavior. The self-resonant frequency differs (90MHz vs. 250MHz), which affects high-frequency performance.

Q: Are there compliance differences?

A: The ISC1210SY1R5K is RoHS non-compliant. The 744764015 is ROHS3 compliant. Applications subject to RoHS regulations require the compliant substitute part.

Q: Do the parts have identical mechanical dimensions?

A: Both parts use the 1210 (3225 Metric) package with matching length (0.126" / 3.20mm) and width (0.098" / 2.49-2.50mm). Height specifications are nearly identical (0.095" vs. 0.094" maximum seated height), ensuring PCB footprint compatibility.
