Substitute Part Grouping Explanation

Substitution eligibility for the CML0306-8N2-JNH is determined by the following critical parameters:

• Inductance value: 8.2 nH with ±5% tolerance
• Package / Case: 0201 (0603 Metric) surface mount
• Current Rating: minimum 180 mA
• DC Resistance: maximum 1.2Ohm
• Operating Temperature Range: minimum -40°C to 85°C coverage
• RoHS Compliance: required for regulatory alignment

The LQP03TG8N2J02D from Murata Electronics meets the core electrical and mechanical requirements for substitution. While this part exhibits differences in construction type (unshielded thick film versus shielded thin film) and certain performance characteristics, it maintains electrical equivalence within the specified tolerance bands and package constraints.

Parameter Comparison

Engineering Selection Recommendations

The LQP03TG8N2J02D is an active product with current manufacturing support and enhanced regulatory compliance (ROHS3). The substitute part exceeds the original specifications in current rating (200 mA versus 180 mA) and operating temperature range (-55°C to 125°C versus -40°C to 85°C), providing design margin for thermal and electrical stress conditions.

The primary design consideration is the transition from shielded to unshielded construction. This difference affects electromagnetic coupling characteristics and may impact performance in noise-sensitive applications. The substitute's higher DC resistance (1.4Ohm Max versus 1.2Ohm Max) represents a 16.7% increase, which may introduce measurable power dissipation changes in high-frequency or high-current circuit paths.

Selection of the LQP03TG8N2J02D is appropriate for applications where the unshielded construction and increased DCR are compatible with circuit design requirements. Verification of electromagnetic compatibility and thermal performance within the specific application context is necessary prior to production implementation.

Frequently Asked Questions (FAQ)

Q: Can the LQP03TG8N2J02D directly replace the CML0306-8N2-JNH in all applications?

A: Both parts share identical inductance values (8.2 nH ±5%), package dimensions (0201/0603 Metric), and mounting type. However, the substitute is unshielded while the original is shielded. Applications requiring shielding for EMI suppression or noise isolation may require circuit-level evaluation before substitution.

Q: What is the impact of the higher DC resistance in the substitute part?

A: The LQP03TG8N2J02D has a maximum DCR of 1.4Ohm compared to 1.2Ohm in the original. This 0.2Ohm difference increases resistive losses proportionally to current flow. In circuits carrying sustained current near the 180 mA rating, this may result in measurable additional power dissipation and heat generation.

Q: Are both parts compatible with the same PCB footprint?

A: Yes. Both components use the 0201 (0603 Metric) package with identical physical dimensions (0.024" L x 0.012" W, 0.61mm x 0.31mm length and 0.31mm width) and maximum seated height (0.013" / 0.33mm). PCB footprints are directly compatible.

Q: What are the compliance differences between these parts?

A: The CML0306-8N2-JNH carries RoHS Compliant status. The LQP03TG8N2J02D carries ROHS3 Compliant status, representing enhanced regulatory alignment. Both parts are REACH Unaffected and carry MSL 1 (Unlimited) moisture sensitivity ratings.

Q: Is the substitute part currently available?

A: The LQP03TG8N2J02D is an active product with 25,398 pieces in current inventory. The original CML0306-8N2-JNH is obsolete with limited remaining stock (1,134 pieces).

Q: How do the frequency characteristics compare?

A: The original part is specified at 100 MHz with a self-resonant frequency of 5GHz. The substitute is specified at 500 MHz with a self-resonant frequency of 4.8GHz. These differences reflect the construction method (thin film versus thick film) and may affect performance in high-frequency applications above 1GHz.
