Key Parameters

Substitute Part Grouping Explanation

Substitution of the SCMS5D12-100 is determined by the following critical parameters:

• Inductance Value: 10 µH at 100 kHz test frequency with ±20% tolerance
• Current Rating: Minimum 1.04 A continuous current capability
• DC Resistance: Maximum 313mOhm to maintain circuit performance
• Shielding: Shielded construction required
• Mounting: Surface mount configuration with matching footprint dimensions (5.20mm x 5.20mm)
• Environmental Compliance: RoHS compliance and MSL rating of 1

The SD14-100-R from Eaton - Electronics Division meets these substitution criteria with equivalent inductance, superior current rating, lower DC resistance, and matching physical dimensions.

Parameter Comparison

Engineering Selection Recommendations

The SD14-100-R is a direct functional substitute for the SCMS5D12-100. The substitute part provides superior electrical performance with higher current rating (1.1 A vs. 1.04 A), lower DC resistance (205.8mOhm vs. 313mOhm), and higher saturation current (1.18A vs. 750mA). Both components maintain identical inductance values, tolerance specifications, and physical footprint dimensions.

The SD14-100-R is currently in active production status, ensuring long-term availability and supply chain continuity. Both parts meet RoHS compliance requirements and carry MSL rating of 1. The primary design consideration is the reduced upper operating temperature limit of the substitute (85°C vs. 125°C); applications requiring operation above 85°C require thermal analysis or alternative component selection.

Frequently Asked Questions (FAQ)

Q: Can the SD14-100-R be used as a direct replacement for SCMS5D12-100 in existing designs?

A: Yes, the SD14-100-R is electrically and mechanically compatible. Both components share identical inductance values, tolerance specifications, and footprint dimensions (5.20mm x 5.20mm). The substitute offers improved electrical characteristics with lower DC resistance and higher current rating.

Q: What is the impact of the height difference between these components?

A: The SD14-100-R has a maximum seated height of 0.057" (1.45mm) compared to 0.049" (1.25mm) for the SCMS5D12-100. This 0.008" (0.20mm) difference is within typical PCB assembly tolerances and should not impact board-level clearances in standard designs. Verify clearance in applications with height-constrained layouts.

Q: Are there temperature range limitations when substituting?

A: The SD14-100-R operates within -40°C to 85°C, compared to -40°C to 125°C for the SCMS5D12-100. Applications requiring sustained operation above 85°C must evaluate thermal performance or select alternative components rated for higher temperatures.

Q: Do both components meet the same compliance standards?

A: Both parts carry MSL rating of 1 (Unlimited) and meet RoHS compliance. The SCMS5D12-100 is ROHS3 compliant, while the SD14-100-R is RoHS compliant. Both are suitable for standard manufacturing and storage conditions.

Q: What packaging options are available for the SD14-100-R?

A: The SD14-100-R is supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes. Confirm packaging requirements with procurement specifications before ordering.
