Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CW252016-R39G is determined by the following critical parameters:

Electrical Equivalence Requirements:

• Inductance value: 390 nH (±2% tolerance maintained)
• DC Resistance: 1.12Ohm maximum
• Q Factor: 45 @ 100MHz
• Self Resonant Frequency: 500 MHz
• Current Rating: minimum 400 mA

Mechanical Compatibility Requirements:

• Package / Case: 1008 (2520 Metric)
• Mounting Type: Surface Mount
• Shielding: Unshielded

Compliance & Environmental Requirements:

• RoHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• Operating Temperature Range: -40°C ~ 125°C minimum

The LQW2UASR39G00L from Murata Electronics meets all electrical equivalence criteria and mechanical compatibility requirements. The substitute part maintains identical inductance, tolerance, DC resistance, Q factor, and self resonant frequency specifications. Current rating of 470 mA exceeds the minimum 400 mA requirement. Both parts are packaged in 1008 (2520 Metric) format, are unshielded wirewound inductors, and comply with ROHS3 and MSL 1 standards.

Parameter Comparison

Engineering Selection Recommendations

The LQW2UASR39G00L qualifies as a direct substitute for the CW252016-R39G based on matching electrical specifications and mechanical compatibility. Both components are active products with ROHS3 compliance and MSL 1 rating. The substitute part provides a higher current rating (470 mA versus 400 mA), which represents an operational margin advantage. The extended lower temperature operating range of the Murata part (-55°C versus -40°C) provides additional environmental flexibility. Selection between these parts should be based on availability, lead time, and supply chain requirements, as electrical and mechanical performance are equivalent.

Frequently Asked Questions (FAQ)

Q: Can the LQW2UASR39G00L replace the CW252016-R39G in all applications?

A: Yes, the LQW2UASR39G00L meets all electrical and mechanical requirements for direct substitution. Identical inductance (390 nH), tolerance (±2%), DC resistance (1.12Ohm max), Q factor (45 @ 100MHz), and self resonant frequency (500 MHz) specifications ensure functional equivalence. Both parts use the same 1008 (2520 Metric) package and surface mount configuration.

Q: What are the key differences between these two parts?

A: The primary differences are manufacturer (Bourns versus Murata), current rating (400 mA versus 470 mA), and operating temperature range (-40°C ~ 125°C versus -55°C ~ 125°C). The Murata part offers higher current capacity and lower temperature operation. Physical dimensions vary slightly (CW252016-R39G: 2.50mm x 2.00mm x 1.80mm height; LQW2UASR39G00L: 2.62mm x 2.45mm x 2.03mm height).

Q: Are both parts RoHS compliant?

A: Yes, both the CW252016-R39G and LQW2UASR39G00L are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: What inductance frequency test value applies to both parts?

A: Both parts use 25 MHz as the inductance frequency test specification.

Q: Can I use the substitute part in high-temperature applications?

A: Both parts operate to 125°C maximum. The Murata LQW2UASR39G00L extends operation to -55°C minimum, providing broader low-temperature capability than the Bourns part at -40°C minimum.
