Key Parameters

Substitute Part Grouping Explanation

Substitution of the CWL0306-3N3-BNH is determined by the following critical parameters:

• Inductance Value: 3.3 nH (primary electrical requirement)
• Package Format: 0201 (0603 Metric) surface mount (physical compatibility)
• Current Rating: Minimum 800 mA (electrical performance requirement)
• DC Resistance: Maximum 90mOhm (electrical performance requirement)
• Operating Temperature Range: Minimum -40°C ~ 125°C (environmental requirement)

The LQP03PN3N3C02D from Murata Electronics meets these substitution criteria. While this part differs in construction type (unshielded thick film versus shielded thin film) and has a lower Q factor at 500MHz, it maintains electrical compatibility through equivalent inductance value, current rating, DC resistance specification, package format, and operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

The LQP03PN3N3C02D is an active product with current manufacturing support and improved compliance status (ROHS3 Compliant with REACH Unaffected designation). The substitute part maintains all critical electrical parameters required for functional equivalence: identical inductance value, equivalent current rating, superior DC resistance specification, and compatible operating temperature range.

The primary design consideration is the difference in shielding architecture. The main part employs shielded construction while the substitute uses unshielded design. Applications requiring electromagnetic shielding characteristics specific to the thin film shielded construction may require circuit-level evaluation. The substitute part's lower Q factor (10 versus 25 at 500MHz) and reduced self-resonant frequency (5.5GHz versus 7GHz) should be assessed within the context of the specific application frequency range and performance requirements.

Frequently Asked Questions (FAQ)

Q: Can the LQP03PN3N3C02D directly replace the CWL0306-3N3-BNH in all applications?

A: The LQP03PN3N3C02D meets the core electrical substitution criteria: 3.3 nH inductance, 800 mA current rating, 80mOhm DC resistance, and 0201 package format. However, applications sensitive to shielding characteristics or operating at frequencies near the self-resonant point should evaluate the differences in construction type and frequency response.

Q: What are the key differences between these parts?

A: The main differences are construction type (shielded thin film versus unshielded thick film), Q factor at 500MHz (25 versus 10), self-resonant frequency (7GHz versus 5.5GHz), and inductance tolerance (±0.1nH versus ±0.2nH). Both parts share identical package format, current rating, and operating temperature range.

Q: Is the substitute part available in the same packaging format?

A: Yes. Both parts use the 0201 (0603 Metric) surface mount package with identical physical dimensions of 0.024" L x 0.012" W (0.60mm x 0.30mm). The substitute part is available in Tape & Reel (TR) packaging with significantly higher inventory availability.

Q: What compliance certifications apply to the substitute part?

A: The LQP03PN3N3C02D is ROHS3 Compliant and REACH Unaffected, providing enhanced regulatory compliance compared to the obsolete main part.
