CSBX1275-1R5M Equivalent & Substitute Parts

Part Overview

The CSBX1275-1R5M is a high saturation power inductor manufactured by CODACA. This shielded wirewound inductor is designed for surface mount applications requiring 1.5 µH inductance with a 28 A current rating and enhanced saturation performance at 54 A. The component features a metal composite core with low DC resistance of 1.61 mOhm maximum, operating across an extended temperature range of -55°C to 150°C. The part maintains Active product status and is ROHS3 compliant with unlimited moisture sensitivity rating. Equivalent and substitute parts are identified based on matching electrical specifications, mechanical dimensions, and performance characteristics within the CSBX1275 series.

Substitute Part Grouping Explanation

Substitution for the CSBX1275-1R5M is determined by strict equivalence across the following critical parameters:

Electrical Specifications:

• Inductance value of 1.5 µH with ±20% tolerance
• Current rating of 28 A minimum
• Saturation current (Isat) of 54 A
• DC resistance not exceeding 1.61 mOhm

Mechanical & Physical Specifications:

• Shielded wirewound construction with metal composite core
• Surface mount configuration
• Nonstandard package dimensions: 0.543" L x 0.504" W x 0.299" H maximum seated height
• Tape & Reel packaging format

Environmental & Compliance:

• Operating temperature range of -55°C to 150°C
• ROHS3 compliance
• Moisture sensitivity level 1 (unlimited)

Parts meeting all these parameters within the CSBX1275 series are classified as direct equivalents. No parameter relaxation or derating is applied in this substitution analysis.

Engineering Selection Recommendations

The CSBX1275-1R5M maintains Active product status with full ROHS3 compliance and REACH unaffected classification. Selection of equivalent parts from the CSBX1275 series requires verification of identical electrical parameters: 1.5 µH inductance, 28 A current rating, and 54 A saturation current. Mechanical compatibility is ensured through matching nonstandard package dimensions and surface mount configuration. The extended operating temperature range of -55°C to 150°C and unlimited moisture sensitivity rating (MSL 1) support deployment across industrial and commercial applications. All substitute parts must maintain identical DC resistance specifications not exceeding 1.61 mOhm maximum to preserve circuit performance characteristics. Compliance certifications including ROHS3 status and REACH unaffected designation must be confirmed for each substitute part prior to procurement.

Frequently Asked Questions (FAQ)

Q: What defines an equivalent part for the CSBX1275-1R5M?

A: An equivalent part must match all electrical specifications (1.5 µH inductance, 28 A current rating, 54 A saturation current, 1.61 mOhm maximum DC resistance), mechanical dimensions (0.543" L x 0.504" W x 0.299" H), core material (metal composite), shielding configuration, and environmental ratings (-55°C to 150°C operating range). The part must be manufactured by CODACA within the CSBX1275 series and maintain ROHS3 compliance.

Q: Can parts with different inductance values substitute for the CSBX1275-1R5M?

A: No. The inductance value of 1.5 µH is a critical electrical parameter. Parts with different inductance values do not qualify as substitutes and will not function identically in the circuit.

Q: Are there current rating variations within acceptable substitution limits?

A: No. The 28 A current rating and 54 A saturation current are fixed specifications for substitution. Parts with lower current ratings or saturation currents do not meet the substitution criteria.

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

A: The metal composite core material directly affects the inductor's saturation characteristics and DC resistance. Substitutes must use identical metal composite core construction to maintain the specified high saturation performance and 1.61 mOhm maximum DC resistance.

Q: Does the shielded configuration affect substitution compatibility?

A: Yes. The shielded wirewound design is essential for EMI performance and circuit integration. Unshielded or differently shielded inductors are not acceptable substitutes.

Q: What packaging format is required for the CSBX1275-1R5M?

A: The part is supplied in Tape & Reel (TR) packaging format for automated assembly. Substitute parts must maintain identical packaging to ensure compatibility with pick-and-place equipment and assembly processes.

Q: Are there compliance considerations for substitute part selection?

A: Yes. All substitute parts must maintain ROHS3 compliance and REACH unaffected status. These certifications are mandatory for applications subject to environmental and regulatory requirements.

Q: What is the moisture sensitivity level, and why does it matter?

A: The CSBX1275-1R5M carries MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. Substitute parts must maintain this same MSL 1 classification to eliminate moisture-related handling and storage constraints.

Q: Can the CSBX1275-1R5M be used in applications requiring different operating temperatures?

A: The part is rated for -55°C to 150°C operation. Applications requiring operation outside this range require alternative components with extended temperature specifications.

Q: What is the test frequency, and does it affect substitution?

A: The inductance value is measured at 100 kHz test frequency. Substitute parts must be characterized at the same test frequency to ensure accurate inductance matching and circuit performance.
