Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SCMS5D14-2R0 is determined by the following critical parameters:

• Inductance value: 2 µH (exact match required)
• Current rating: minimum 2.37 A continuous
• DC resistance: maximum 49 mOhm
• Saturation current: minimum 2.56 A
• Shielding: shielded configuration required
• Operating temperature range: -40°C to 125°C minimum
• Mounting type: surface mount
• Package footprint: 5.20mm x 5.20mm maximum
• Regulatory compliance: ROHS3 compliant

The SD53-2R0-R meets all substitution criteria with improved electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The SD53-2R0-R is a qualified substitute for the SCMS5D14-2R0 based on the following engineering criteria:

• Both components meet identical inductance specifications at 2 µH
• The SD53-2R0-R exceeds minimum current rating requirements (2.64 A vs. 2.37 A required)
• DC resistance of the substitute is lower (27 mOhm vs. 49 mOhm maximum), resulting in reduced power dissipation
• Saturation current margin is improved with the substitute (3.3 A vs. 2.56 A)
• Both components maintain identical operating temperature range and shielding configuration
• The SD53-2R0-R is actively manufactured by Eaton, ensuring long-term supply availability
• Both components carry ROHS3 compliance certification
• Physical footprint is compatible; the substitute has increased height (3.00mm vs. 1.50mm), requiring PCB layout verification

Frequently Asked Questions (FAQ)

Q: Can the SD53-2R0-R be used as a direct replacement for the SCMS5D14-2R0?

A: Yes, the SD53-2R0-R meets all electrical substitution criteria. The primary consideration is the increased height dimension (3.00mm vs. 1.50mm), which must be verified against PCB clearance and assembly constraints.

Q: What are the key differences between these two inductors?

A: The SD53-2R0-R provides superior electrical performance with lower DC resistance (27 mOhm vs. 49 mOhm), higher current rating (2.64 A vs. 2.37 A), and tighter inductance tolerance (±20% vs. ±30%). Both maintain identical inductance value, operating temperature range, and shielding characteristics.

Q: Is the packaging compatible between these parts?

A: Both components use identical footprint dimensions (5.20mm x 5.20mm). The SD53-2R0-R has a greater seated height (3.00mm vs. 1.50mm), which may affect PCB layout and component clearance. Verify available vertical space in your assembly before implementation.

Q: Are both parts RoHS compliant?

A: Yes, both the SCMS5D14-2R0 and SD53-2R0-R are ROHS3 compliant and REACH unaffected.

Q: Why is the original part obsolete?

A: The SCMS5D14-2R0 is no longer manufactured by Signal Transformer. The SD53-2R0-R from Eaton provides equivalent functionality with active production status and improved electrical specifications.

Q: What is the inductance tolerance difference, and does it matter?

A: The SCMS5D14-2R0 has ±30% tolerance, while the SD53-2R0-R has ±20% tolerance. The tighter tolerance of the substitute provides better circuit performance consistency and reduced variation across production batches.
