Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ASMPH-0805-3R3M-T is determined by the following critical parameters:

• Inductance Value: 3.3 µH (±20% tolerance)
• Package / Case: 0805 (2012 Metric) form factor
• Shielding Type: Shielded construction
• Core Material: Ferrite
• Mounting Type: Surface Mount
• Current Rating: Minimum 800 mA (design margin consideration)
• DC Resistance: Maximum 207mOhm (acceptable variance within application tolerance)
• Self Resonant Frequency: 30MHz
• Compliance: ROHS3 compliant, REACH unaffected

The LQM21PN3R3MG0D from Murata Electronics meets all substitution criteria within these defined parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the ASMPH-0805-3R3M-T and LQM21PN3R3MG0D maintain Active product status and satisfy ROHS3 compliance and REACH unaffected certifications. The Murata LQM21PN3R3MG0D provides an extended operating temperature range (-55°C to 125°C) compared to the Abracon part (-40°C to 85°C), supporting applications requiring broader thermal performance. The current rating differential (900 mA vs. 800 mA) and DC resistance variance (200mOhm vs. 207mOhm Max) remain within acceptable engineering tolerances for equivalent substitution. Component selection should be based on application-specific thermal requirements, supply availability, and design margin specifications.

Frequently Asked Questions (FAQ)

Q: Can the LQM21PN3R3MG0D replace the ASMPH-0805-3R3M-T in all applications?

A: The LQM21PN3R3MG0D is electrically and mechanically compatible as a substitute. Both components share identical inductance values (3.3 µH), package dimensions (0805 / 2012 Metric), and core material (ferrite). The Murata part operates at 800 mA versus 900 mA for the Abracon part. Applications operating below 800 mA continuous current experience no functional difference. Applications requiring the full 900 mA rating should evaluate the design margin impact.

Q: Are there package compatibility concerns?

A: No. Both parts use the 0805 (2012 Metric) surface mount package with identical footprint dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm) and maximum seated height (0.039" / 1.00mm). PCB layout and assembly processes require no modification.

Q: How do the DC resistance values compare?

A: The ASMPH-0805-3R3M-T specifies 200mOhm, while the LQM21PN3R3MG0D specifies 207mOhm maximum. This 7mOhm variance represents a 4.6% difference and remains within typical circuit design tolerances for inductor applications.

Q: What is the temperature operating range difference?

A: The Abracon part operates from -40°C to 85°C. The Murata part extends this range to -55°C to 125°C. Applications operating within the Abracon temperature window experience identical thermal performance. Applications requiring extended low-temperature operation (-55°C) or high-temperature operation (above 85°C) benefit from the Murata part's broader range.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the ASMPH-0805-3R3M-T and LQM21PN3R3MG0D are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.
