Key Parameters

Substitute Part Grouping Explanation

Substitution of the ACM2520-301-2P is determined by strict equivalence across the following critical parameters:

• Electrical Performance: Impedance of 300 ohms at 100 MHz, current rating of 400mA maximum, and DC resistance not exceeding 350mOhm
• Physical Compatibility: Surface mount package with identical footprint dimensions (2.50mm x 2.00mm) and height (1.30mm), maintaining 4-pad horizontal configuration
• Functional Classification: 2-line common mode choke for signal line filtering applications
• Environmental Ratings: Operating temperature range and moisture sensitivity level

The ACM2520-301-2P-T002 meets all these criteria and is classified as an active product, providing continuity for designs currently using the obsolete ACM2520-301-2P.

Parameter Comparison

Engineering Selection Recommendations

The ACM2520-301-2P-T002 is the direct substitute for the obsolete ACM2520-301-2P. Both components share identical electrical specifications, physical dimensions, and functional characteristics. The substitute part offers the advantage of active product status, ensuring ongoing availability and supply chain continuity.

The ACM2520-301-2P-T002 provides an extended operating temperature range (-40°C to 85°C versus -25°C to 85°C) and carries ROHS3 compliance certification, meeting current regulatory requirements for electronic component manufacturing and distribution.

For applications currently specified with ACM2520-301-2P, direct substitution with ACM2520-301-2P-T002 is appropriate without circuit redesign or performance degradation.

Frequently Asked Questions (FAQ)

Q: Can ACM2520-301-2P-T002 be used as a direct replacement for ACM2520-301-2P?

A: Yes. Both parts are manufactured by TDK Corporation and share identical electrical performance (300 ohms @ 100 MHz, 400mA current rating, 350mOhm DCR), physical dimensions (2.50mm x 2.00mm), and package configuration (Horizontal, 4 PC Pad). The substitute part is actively produced and available.

Q: What is the difference in operating temperature range between these parts?

A: The ACM2520-301-2P operates from -25°C to 85°C, while the ACM2520-301-2P-T002 operates from -40°C to 85°C. The substitute part supports a wider low-temperature range, making it suitable for applications requiring extended cold-temperature performance.

Q: Does the substitute part meet current compliance standards?

A: The ACM2520-301-2P-T002 is ROHS3 compliant and carries REACH Unaffected status, meeting current regulatory requirements for electronic components in most markets.

Q: Are there packaging differences between these parts?

A: The ACM2520-301-2P is supplied in standard packaging, while the ACM2520-301-2P-T002 is available in Cut Tape (CT) and Digi-Reel® packaging options, providing flexibility for different procurement and assembly workflows.

Q: What is the footprint compatibility for PCB design?

A: Both parts use identical surface mount footprints with 4-pad horizontal configuration and matching dimensions of 2.50mm length by 2.00mm width by 1.30mm maximum height. No PCB layout modifications are required for substitution.
