Key Parameters

Substitute Part Grouping Explanation

Substitution of the ACM2520-451-2P is determined by strict equivalence across the following critical parameters:

• Electrical Performance: Impedance of 450 Ohms @ 100 MHz, current rating of 350mA maximum, and DC resistance of 400mOhm maximum
• Mechanical Compatibility: Surface mount configuration with identical footprint dimensions (2.50mm x 2.00mm) and height (1.30mm), package type Horizontal 4 PC Pad
• Functional Classification: 2-line common mode choke for signal line filtering applications
• Environmental Ratings: DC voltage rating of 20V, operating temperature range, and moisture sensitivity level

The ACM2520-451-2P-T002 meets all substitution criteria as a direct equivalent from the same manufacturer and series, with identical electrical and mechanical specifications. The primary distinction is packaging format and product status.

Frequently Asked Questions (FAQ)

Q: Can the ACM2520-451-2P-T002 be used as a direct replacement for the ACM2520-451-2P?

A: Yes. The ACM2520-451-2P-T002 is electrically and mechanically equivalent to the ACM2520-451-2P. Both components have identical impedance (450 Ohms @ 100 MHz), current rating (350mA), DC resistance (400mOhm), footprint dimensions (2.50mm x 2.00mm), and package configuration. The substitute is suitable for direct PCB replacement.

Q: What is the difference between the ACM2520-451-2P and ACM2520-451-2P-T002?

A: The primary differences are product status and packaging format. The ACM2520-451-2P is obsolete and supplied in bulk packaging, while the ACM2520-451-2P-T002 is active and supplied in Tape & Reel format. The ACM2520-451-2P-T002 also features an extended operating temperature range (-40°C to 85°C versus -25°C to 85°C) and carries ROHS3 compliance certification.

Q: Are there any compatibility concerns when substituting the ACM2520-451-2P with the ACM2520-451-2P-T002?

A: No compatibility concerns exist. The components share identical electrical specifications and mechanical dimensions. The Tape & Reel packaging of the substitute is a standard format compatible with automated assembly processes.

Q: Does the extended temperature range of the ACM2520-451-2P-T002 affect its performance in standard applications?

A: No. The extended lower temperature limit of the ACM2520-451-2P-T002 (-40°C) provides additional operational margin compared to the original part (-25°C). This enhancement does not affect performance in applications within the original temperature range.

Q: Is the ACM2520-451-2P-T002 RoHS compliant?

A: Yes. The ACM2520-451-2P-T002 is ROHS3 compliant, meeting current regulatory requirements for restricted substances in electrical and electronic equipment.
