Substitute Part Grouping Explanation

Substitute parts for the CSBX1275-5R6M are identified through parametric equivalence matching. The substitution logic is based on the following critical parameters that must align with the main part specification:

Electrical Parameters (Must Match):

• Inductance value: 5.6 µH
• Inductance tolerance: ±20%
• Current rating: 17 A minimum
• Saturation current: 27 A minimum
• DC resistance: 5.3 mOhm maximum

Mechanical Parameters (Must Match):

• Core material: Metal Composite
• Shielding: Shielded configuration
• Mounting type: Surface Mount
• Package dimensions: 13.80 mm L × 12.80 mm W × 7.60 mm H maximum

Environmental & Compliance Parameters (Must Match):

• Operating temperature range: -55°C to 150°C minimum
• RoHS status: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

Parts meeting all specified parameters within stated tolerances are classified as direct parametric equivalents and may be substituted without circuit redesign.

Parameter Comparison

Engineering Selection Recommendations

The CSBX1275-5R6M is an Active product with full ROHS3 compliance and REACH unaffected status, confirming its suitability for current and future production environments. The component carries Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements during storage or assembly.

When selecting substitute inductors, prioritize parts with identical Active product status to ensure long-term availability and consistent manufacturing processes. Verify that substitute candidates maintain ROHS3 compliance and equivalent environmental certifications to meet regulatory requirements in target markets.

The shielded metal composite core construction with specified DC resistance characteristics is critical for applications requiring controlled electromagnetic interference and thermal performance. Substitute parts must maintain these core material and shielding specifications to preserve circuit performance and EMI characteristics.

Surface mount packaging with nonstandard dimensions (13.80 × 12.80 × 7.60 mm) requires physical footprint verification during PCB layout. Substitute parts must match these exact dimensions to ensure mechanical compatibility with existing board designs and assembly processes.

Frequently Asked Questions (FAQ)

Q: What makes a part a valid substitute for the CSBX1275-5R6M?

A: A valid substitute must match all specified electrical parameters (5.6 µH inductance, 17 A current rating, 27 A saturation current, 5.3 mOhm maximum DCR), mechanical specifications (metal composite core, shielded configuration, 13.80 × 12.80 × 7.60 mm dimensions), and compliance certifications (ROHS3, MSL 1). The part must also maintain Active product status.

Q: Can I use a different inductance value if it falls within the ±20% tolerance?

A: No. The ±20% tolerance specification defines the acceptable manufacturing variation for the 5.6 µH nominal value. Substitute parts must be specified as 5.6 µH inductors. Parts with different nominal inductance values (such as 4.7 µH or 6.8 µH) are not substitutes, regardless of tolerance overlap.

Q: Are there any current rating considerations for substitution?

A: Substitute parts must maintain a minimum 17 A current rating and 27 A saturation current. Parts with lower current ratings cannot be substituted. Parts with higher current ratings are acceptable from an electrical standpoint but must be evaluated for physical fit and cost implications.

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

A: The metal composite core material directly affects inductor performance characteristics including saturation behavior, temperature stability, and electromagnetic shielding effectiveness. Substitute parts must use identical metal composite core construction. Alternative core materials (ferrite, iron powder) produce different electrical characteristics and are not acceptable substitutes.

Q: Does the shielded configuration affect substitution?

A: Yes. The shielded configuration is essential for EMI control and circuit performance. Only shielded inductors with equivalent shielding effectiveness are acceptable substitutes. Unshielded or partially shielded inductors will not provide equivalent electromagnetic performance.

Q: What is the importance of the nonstandard package dimensions?

A: The 13.80 × 12.80 × 7.60 mm nonstandard package dimensions are fixed by the PCB footprint design. Substitute parts must match these exact dimensions for mechanical compatibility. Dimensional variations will result in assembly fit issues or require PCB redesign.

Q: How does Moisture Sensitivity Level 1 affect handling and storage?

A: MSL 1 (Unlimited) indicates the component has no moisture sensitivity restrictions. Standard dry storage conditions are sufficient. No special moisture-barrier packaging, baking procedures, or time-limited shelf life constraints apply to this component or its substitutes.

Q: Why is ROHS3 compliance important for substitution?

A: ROHS3 compliance ensures the component meets current environmental regulations for restricted substances. Substitute parts must maintain ROHS3 compliance to satisfy regulatory requirements in target markets and ensure consistency with other components in the assembly.

Q: Can I substitute with a part from a different manufacturer?

A: Substitution is based on parametric equivalence. Parts from other manufacturers meeting all specified electrical, mechanical, and compliance parameters are technically equivalent. However, verify that alternative manufacturer parts maintain identical specifications, certifications, and long-term availability before implementation.

Q: What should I verify before implementing a substitute part?

A: Confirm that the substitute part matches all parameters listed in the Key Parameters table, maintains Active product status, carries ROHS3 compliance, and fits the specified package dimensions. Review the substitute part's datasheet to verify DC resistance, saturation characteristics, and operating temperature range align with the original specification.
