Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PMC0805-152 is determined by the following critical parameters:

• Impedance value: 1.5 kOhms (measured at operating frequency)
• Package type: 0805 (2012 Metric) surface mount
• Current rating: 100mA minimum
• DC resistance: Must not exceed 1 Ohm significantly
• Number of lines: Single line configuration
• Operating temperature range: -55°C to 125°C minimum

The MG2029-152Y qualifies as a direct substitute based on matching impedance (1.5 kOhms), identical package format, equivalent current rating (100mA), compatible operating temperature range, and single-line configuration. The substitute exhibits improved DC resistance (550mOhm versus 1 Ohm) and operates at a higher frequency reference point (100 MHz versus 50 MHz), both favorable characteristics for EMI suppression applications.

Engineering Selection Recommendations

The MG2029-152Y is the qualified substitute for the obsolete PMC0805-152. Selection of this substitute is supported by the following factors:

• Active product status ensures long-term availability and supply chain continuity
• ROHS3 compliance satisfies current regulatory requirements, whereas the original part is non-compliant
• Electrical parameters remain within acceptable tolerance: impedance value matches at 1.5 kOhms, current rating is equivalent at 100mA, and DC resistance is improved at 550mOhm
• Physical package dimensions are compatible with 0805 (2012 Metric) footprints, with height variation (1.10mm versus 0.90mm) remaining within standard PCB assembly tolerances
• Operating temperature range is identical, ensuring thermal performance equivalence

Frequently Asked Questions (FAQ)

Q: Can the MG2029-152Y be used as a direct replacement for PMC0805-152 in existing designs?

A: Yes. Both components share identical impedance values (1.5 kOhms), package format (0805), current ratings (100mA), and operating temperature ranges (-55°C to 125°C). The substitute exhibits lower DC resistance and higher frequency reference, both favorable for EMI suppression performance.

Q: What is the significance of the impedance frequency difference (50 MHz versus 100 MHz)?

A: Impedance frequency indicates the reference point at which the specified impedance value is measured. The MG2029-152Y's higher reference frequency (100 MHz) reflects improved performance characteristics across a broader frequency spectrum, making it suitable for applications requiring EMI suppression across extended frequency ranges.

Q: Does the height difference between parts affect PCB assembly compatibility?

A: The height difference (0.90mm versus 1.10mm) is within standard surface mount assembly tolerances for 0805 packages. Both components are compatible with standard pick-and-place equipment and reflow processes.

Q: Why is RoHS compliance important for this substitution?

A: The original PMC0805-152 is RoHS non-compliant, while the MG2029-152Y is ROHS3 compliant. Current manufacturing and distribution standards require RoHS compliance for new component procurement. The substitute meets these regulatory requirements.

Q: Are there any electrical performance trade-offs when using the substitute?

A: No trade-offs exist. The MG2029-152Y provides equivalent or improved electrical performance: impedance remains at 1.5 kOhms, current rating is maintained at 100mA, and DC resistance is reduced from 1 Ohm to 550mOhm, resulting in lower insertion loss.
