Substitute Part Grouping Explanation

Substitute parts for the CSBX1809-100M are identified through parametric equivalence matching. The substitution logic is based on the following critical parameters that must align for direct interchangeability:

Electrical Parameters (Must Match):

• Inductance value: 10 µH
• Inductance tolerance: ±20%
• Current rating: 16 A minimum
• Saturation current (Isat): 26 A minimum
• DC resistance (DCR): 6.9 mOhm maximum

Mechanical Parameters (Must Match):

• Core material: Metal Composite
• Shielding: Shielded configuration
• Mounting type: Surface Mount
• Physical dimensions: 19.30mm L × 18.20mm W × 9.20mm H maximum

Compliance Parameters (Must Match):

• RoHS3 compliance
• AEC-Q200 automotive qualification
• Operating temperature range: -55°C to 150°C minimum

Parts meeting all specified parameters within stated tolerances are classified as parametric equivalents and direct substitutes.

Frequently Asked Questions (FAQ)

Q: What defines a direct substitute for the CSBX1809-100M?

A: A direct substitute must match all electrical parameters (10 µH inductance, ±20% tolerance, 16 A current rating, 26 A saturation current, 6.9 mOhm maximum DCR), mechanical specifications (19.30 × 18.20 × 9.20 mm dimensions, metal composite core, shielded configuration), and compliance certifications (AEC-Q200, ROHS3, -55°C to 150°C operating range).

Q: Can inductors with higher current ratings substitute for the CSBX1809-100M?

A: Higher current ratings are acceptable provided all other electrical parameters remain within specification. The 16 A current rating and 26 A saturation current establish minimum performance thresholds; components exceeding these values maintain compatibility if inductance, tolerance, DCR, and mechanical dimensions remain unchanged.

Q: Are mechanical dimensions critical for substitution?

A: Yes. The nonstandard package dimensions of 19.30mm length, 18.20mm width, and 9.20mm maximum height are critical for PCB layout compatibility. Substitute parts must conform to these exact dimensions to ensure proper mounting and thermal performance.

Q: What is the significance of the metal composite core material?

A: Metal composite cores provide controlled saturation characteristics and electromagnetic shielding essential for high-current applications. Substitutes must use identical core material to maintain inductance stability under saturation conditions and preserve shielding effectiveness.

Q: Does AEC-Q200 certification affect substitute selection?

A: AEC-Q200 certification indicates automotive-grade reliability and qualification testing. Substitute parts should maintain equivalent or superior automotive qualification to ensure consistent performance in regulated applications.

Q: Is the ±20% inductance tolerance acceptable for all applications?

A: The ±20% tolerance is specified for the CSBX1809-100M. Applications requiring tighter tolerance control must verify that substitute components meet the same tolerance specification or tighter limits.

Q: What role does the shielded configuration play in substitution?

A: Shielding reduces electromagnetic interference and cross-coupling in multi-inductor circuits. Substitute parts must maintain shielded configuration to preserve EMI performance and circuit stability.
