Substitute Part Grouping Explanation

Substitution of the ACM2520-102-2P is determined by strict equivalence across the following critical parameters:

• Electrical Performance: Impedance of 1 kOhms @ 100 MHz, current rating of 200mA, and DC resistance maximum of 900mOhm
• Physical Compatibility: Surface mount package with identical dimensions (2.50mm x 2.00mm) and height (1.30mm), horizontal 4-pad configuration
• Functional Specification: 2-line common mode choke for signal line filtering
• Environmental Ratings: DC voltage rating of 20V and operating temperature range support
• Packaging Format: Cut Tape (CT) and Digi-Reel® availability for production environments

The ACM2520-102-2P-T002 meets all substitution criteria as a direct equivalent with identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The ACM2520-102-2P-T002 is the direct substitute for the obsolete ACM2520-102-2P. Selection of the substitute part is based on the following factors:

• Product Status: The main part is obsolete, while the substitute maintains active product status with ongoing manufacturer support
• Compliance: The substitute is ROHS3 compliant, meeting current regulatory requirements for electronic components
• Electrical Equivalence: All critical electrical parameters are identical, ensuring functional compatibility in existing circuit designs
• Physical Compatibility: Identical package dimensions and pad configuration enable direct PCB layout compatibility without redesign
• Environmental Performance: The substitute offers an extended lower operating temperature limit (-40°C versus -25°C), providing broader environmental coverage
• Procurement: The substitute is available in standard production packaging formats (Cut Tape and Digi-Reel®), supporting volume manufacturing workflows

Frequently Asked Questions (FAQ)

Q: Can the ACM2520-102-2P-T002 be used as a direct replacement for the ACM2520-102-2P?

A: Yes. The substitute part is electrically and mechanically equivalent. All critical parameters including impedance, current rating, DC resistance, voltage rating, and physical dimensions are identical. PCB layout modifications are not required.

Q: What is the difference between the main part and the substitute?

A: The primary differences are product status (obsolete versus active), compliance certification (ROHS3 for the substitute), packaging format availability (Cut Tape and Digi-Reel® for the substitute), and operating temperature range (-40°C to 85°C for the substitute versus -25°C to 85°C for the main part).

Q: Are there any compatibility concerns with the substitute part?

A: No compatibility concerns exist. The substitute maintains identical electrical performance and physical form factor. The extended lower temperature rating of the substitute provides additional environmental margin.

Q: What packaging formats are available for the substitute part?

A: The ACM2520-102-2P-T002 is available in Cut Tape (CT) and Digi-Reel® packaging formats, suitable for both manual and automated assembly processes.

Q: Is the substitute part RoHS compliant?

A: Yes. The ACM2520-102-2P-T002 is ROHS3 compliant, meeting current environmental and regulatory standards for electronic components.
