ACM-31-222M-T Equivalent & Substitute Parts

Part Overview

The ACM-31-222M-T is a 2-line common mode choke (CMC) surface mount component manufactured by Abracon LLC. This signal line filter is designed for applications requiring 2.2 kOhms impedance at 100 MHz with a maximum current rating of 200mA and 1.2Ohm DC resistance. The component is Active in product status and widely used in signal conditioning and EMI suppression applications. Substitute parts are identified when equivalent electrical and mechanical parameters are required due to inventory constraints, manufacturing discontinuation, or design flexibility needs.

Substitute Part Grouping Explanation

The DLW31SN222SQ2L manufactured by Murata Electronics is identified as a parametric equivalent to the ACM-31-222M-T. Substitution is valid based on the following criteria:

Electrical Parameters (Identical):

• Filter Type: Signal Line
• Number of Lines: 2
• Impedance @ Frequency: 2.2 kOhms @ 100 MHz
• Current Rating (Max): 200mA
• DC Resistance (DCR) (Max): 1.2Ohm
• Voltage Rating - DC: 50V
• Operating Temperature: -40°C ~ 85°C

Mechanical Parameters (Compatible):

• Mounting Type: Surface Mount
• Package / Case: Horizontal, 4 PC Pad
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Physical Dimensions (Minor Variation):

• ACM-31-222M-T: 0.118" L x 0.063" W x 0.079" H (3.00mm x 1.60mm x 2.00mm)
• DLW31SN222SQ2L: 0.126" L x 0.063" W x 0.083" H (3.20mm x 1.60mm x 2.10mm)

The dimensional differences are within acceptable tolerances for standard PCB footprint compatibility in horizontal 4-pad configurations.

Parameter Comparison

Engineering Selection Recommendations

Both the ACM-31-222M-T and DLW31SN222SQ2L are Active product status components with identical electrical specifications and compatible mechanical configurations. Selection between these parts is based on:

Compliance & Certifications: Both components are ROHS3 Compliant and REACH Unaffected, meeting equivalent regulatory requirements for industrial and commercial applications.

Packaging Availability: The ACM-31-222M-T is supplied in Tape & Reel (TR) format, while the DLW31SN222SQ2L is available in Cut Tape (CT) & Digi-Reel® format. Packaging selection depends on assembly line requirements and volume specifications.

Physical Footprint: The dimensional variation (0.20mm length and 0.10mm height difference) is within standard PCB design tolerances for horizontal 4-pad surface mount configurations and does not affect electrical performance or circuit board layout compatibility.

Frequently Asked Questions (FAQ)

Q: Can the DLW31SN222SQ2L replace the ACM-31-222M-T in existing designs?

A: Yes. The DLW31SN222SQ2L is electrically and mechanically equivalent. All critical parameters including impedance, current rating, DC resistance, voltage rating, and operating temperature are identical. The minor dimensional differences are within acceptable PCB footprint tolerances.

Q: What is the significance of the packaging format difference?

A: The ACM-31-222M-T uses Tape & Reel (TR) packaging, while the DLW31SN222SQ2L uses Cut Tape (CT) & Digi-Reel® packaging. Both formats are standard for surface mount assembly. Selection depends on your manufacturing process and volume requirements. Tape & Reel is typical for high-volume automated assembly, while Cut Tape is suitable for lower volumes or mixed component sourcing.

Q: Are there any compliance or certification differences?

A: No. Both components are ROHS3 Compliant and REACH Unaffected, meeting identical regulatory standards for environmental and hazardous substance restrictions.

Q: How do the physical dimensions affect PCB design?

A: The ACM-31-222M-T measures 3.00mm x 1.60mm x 2.00mm, while the DLW31SN222SQ2L measures 3.20mm x 1.60mm x 2.10mm. These differences are minor and compatible with standard horizontal 4-pad surface mount footprints. PCB layout modifications are not required for substitution.

Q: What is the Moisture Sensitivity Level (MSL) for both parts?

A: Both components have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard storage and handling procedures apply without special desiccant or humidity control requirements.
