Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CMF16-153131-B are identified within the Triad Magnetics CMF series based on the following allowable parameter variations:

Matching Parameters (Required for Substitution):

• Filter Type: Power Line
• Number of Lines: 2
• Mounting Type: Through Hole
• Package / Case: Vertical, 4 PC Pin
• Voltage Rating - AC: 300V
• Operating Temperature Range: -40°C to 105°C
• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected

Allowable Parameter Variations:

• Inductance @ Frequency: Higher inductance values (27 mH @ 10 kHz) are acceptable for applications requiring increased filtering performance
• Current Rating (Max): Higher current ratings (1.4A) provide additional design margin
• DC Resistance (Max): Slight increases in DCR (484 mOhm) are acceptable within the CMF series design envelope

The substitute parts CMF23H-273141-B and CMF23V-273141-B maintain all critical electrical and mechanical compatibility parameters while offering enhanced inductance and current handling characteristics.

Parameter Comparison

Engineering Selection Recommendations

All three parts—CMF16-153131-B, CMF23H-273141-B, and CMF23V-273141-B—are active products manufactured by Triad Magnetics and maintain full compliance with ROHS3 and REACH regulatory requirements. Selection between these parts is determined by application-specific inductance and current requirements:

CMF16-153131-B is the primary specification with 15 mH inductance and 1.3A current rating. This part provides the baseline filtering performance for standard two-line common mode choke applications.

CMF23H-273141-B and CMF23V-273141-B both provide 27 mH inductance and 1.4A current rating, offering enhanced filtering capability and increased current margin. These parts differ only in physical dimensions: CMF23H-273141-B measures 1.043" L × 0.976" W × 0.551" H, while CMF23V-273141-B measures 1.142" L × 0.591" W × 1.063" H. Physical space constraints in the application determine which substitute is appropriate.

All parts operate across the identical temperature range (-40°C to 105°C) and maintain 300V AC voltage rating, ensuring thermal and electrical compatibility in power line filtering circuits.

Frequently Asked Questions (FAQ)

Q: Can CMF23H-273141-B or CMF23V-273141-B be used as direct replacements for CMF16-153131-B?

A: Yes, both substitute parts maintain identical electrical interface parameters (2-line configuration, 300V AC rating, through-hole mounting, 4-pin vertical package) and regulatory compliance. The higher inductance (27 mH vs. 15 mH) and current rating (1.4A vs. 1.3A) provide enhanced performance characteristics suitable for the same application category.

Q: What is the primary difference between CMF23H-273141-B and CMF23V-273141-B?

A: Both parts have identical electrical specifications (27 mH @ 10 kHz, 1.4A, 484 mOhm DCR). The difference is physical form factor. CMF23H-273141-B is more compact horizontally (1.043" L × 0.976" W), while CMF23V-273141-B is taller (1.063" H vs. 0.551" H). Selection depends on available PCB space and mounting orientation requirements.

Q: Are there any compliance or certification differences between these parts?

A: No. All three parts carry identical ROHS3 compliance and REACH unaffected status. All are active products from Triad Magnetics with equivalent regulatory standing.

Q: What determines whether a higher inductance value is acceptable in my application?

A: Inductance selection is application-dependent. Higher inductance (27 mH) provides greater common mode noise attenuation but may affect circuit impedance and frequency response. Circuit design validation is required to confirm compatibility with the specific filtering requirements.

Q: Can these parts be used interchangeably on the same PCB layout?

A: CMF16-153131-B and CMF23H-273141-B share similar footprints and may be interchangeable on the same layout. CMF23V-273141-B has a significantly different height profile and requires layout verification before substitution.
