CML0306-22N-JNH Equivalent & Substitute Parts

Part Overview

The CML0306-22N-JNH is a 22 nH shielded thin film inductor manufactured by Delta Electronics/Cyntec, rated for 120 mA maximum current with a DC resistance of 2.55Ohm maximum. This component is designed for surface mount applications in the 0201 (0603 Metric) package format. The product is currently obsolete, making identification of equivalent substitute parts essential for ongoing design support, production continuity, and component sourcing.

Substitute Part Grouping Explanation

Substitution eligibility for the CML0306-22N-JNH is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 22 nH (exact match required)
• Package / Case: 0201 (0603 Metric) (exact match required)
• Mounting Type: Surface Mount (exact match required)

Secondary Compatibility Parameters:

• Current Rating: Substitute must meet or exceed 120 mA
• DC Resistance: Lower DCR values are acceptable; higher values require circuit validation
• Operating Temperature Range: Substitute must support the application's thermal requirements
• RoHS / REACH Compliance: Substitute must maintain regulatory compliance status

The LQP03TN22NH02D from Murata Electronics qualifies as a direct substitute based on matching inductance value, package format, and mounting type. While the substitute exhibits different shielding characteristics (unshielded vs. shielded) and material composition (thick film vs. thin film), these differences do not preclude substitution when circuit design accounts for electromagnetic coupling and frequency response variations.

Parameter Comparison

Engineering Selection Recommendations

The LQP03TN22NH02D is an active product with current manufacturing support and improved regulatory compliance (ROHS3 vs. RoHS). The substitute provides superior electrical performance in current rating (150 mA vs. 120 mA) and lower DC resistance (1.9Ohm vs. 2.55Ohm), reducing power dissipation in the application circuit.

Design consideration: The transition from shielded to unshielded construction and from thin film to thick film technology introduces differences in electromagnetic coupling behavior and frequency response. Circuit validation is required to confirm performance equivalence in applications sensitive to these characteristics, particularly in high-frequency or magnetically coupled environments.

The substitute maintains identical package dimensions and mounting compatibility, enabling direct PCB footprint reuse without layout modification.

Frequently Asked Questions (FAQ)

Q: Can the LQP03TN22NH02D directly replace the CML0306-22N-JNH without circuit modification?

A: Physical and electrical compatibility exists for the 22 nH inductance value and 0201 package format. However, the shift from shielded thin film to unshielded thick film construction may affect circuit performance in applications with tight electromagnetic coupling requirements or specific frequency response specifications. Circuit validation is necessary.

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

A: The LQP03TN22NH02D exhibits 1.9Ohm maximum DCR compared to 2.55Ohm maximum in the original part. This reduction decreases resistive losses and power dissipation, generally providing a performance improvement. No circuit modification is required to accommodate this change.

Q: Does the unshielded design of the substitute affect EMI performance?

A: The unshielded construction of the LQP03TN22NH02D may result in increased electromagnetic radiation and susceptibility compared to the shielded CML0306-22N-JNH. Applications requiring controlled EMI characteristics should evaluate the substitute's performance through circuit testing or electromagnetic simulation.

Q: Are the operating temperature ranges compatible?

A: The substitute supports an extended temperature range (-55°C ~ 125°C) compared to the original part (-40°C ~ 85°C). This provides greater thermal margin for applications operating at elevated or reduced temperatures.

Q: What are the compliance and availability advantages of the substitute?

A: The LQP03TN22NH02D is an active product with 95,400 pieces in stock, compared to the obsolete CML0306-22N-JNH with limited remaining inventory. The substitute meets ROHS3 compliance, representing current regulatory standards. Long-term design support and component availability are assured with the active product.
