Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CML0510-8N2-CNH is determined by the following critical parameters:

Mandatory Matching Criteria:

• Inductance value: 8.2 nH (exact match required)
• Package / Case: 0402 (1005 Metric) (physical compatibility)
• Operating temperature range: -40°C ~ 125°C (minimum requirement)
• Mounting type: Surface Mount (assembly compatibility)

Allowable Variation Parameters:

• Inductance tolerance: ±0.2nH or tighter acceptable
• Current rating: 220 mA or higher acceptable
• DC resistance: Values up to 1.1Ohm acceptable for applications where DCR is not critical
• Shielding: Both shielded and unshielded configurations acceptable depending on EMI requirements

The substitute part 744901082 (Würth Elektronik WE-TCI series) meets all mandatory matching criteria and falls within allowable variation parameters for current rating and DC resistance.

Parameter Comparison

Engineering Selection Recommendations

The CML0510-8N2-CNH is classified as obsolete, necessitating transition to active production alternatives. The Würth Elektronik 744901082 is an active product with current inventory availability (9084 Pcs in stock versus 930 Pcs for the original part).

Both components satisfy RoHS and REACH compliance requirements. The substitute part carries ROHS3 certification, meeting current regulatory standards. Both components maintain identical moisture sensitivity levels and operating temperature specifications.

Selection between the main part and substitute should be based on application-specific requirements regarding shielding and DC resistance characteristics. The substitute part exhibits higher DC resistance (1.1Ohm versus 850mOhm) and lacks shielding, which may impact performance in noise-sensitive or high-frequency applications. Current rating difference (220 mA versus 230 mA) is marginal and acceptable for most applications.

Frequently Asked Questions (FAQ)

Q: Can the 744901082 be used as a direct replacement for the CML0510-8N2-CNH?

A: Physical and electrical compatibility exists for the 0402 package footprint and 8.2 nH inductance value. However, the substitute part is unshielded with higher DC resistance. Application requirements regarding EMI shielding and power dissipation must be evaluated before substitution.

Q: What is the significance of the shielding difference?

A: The main part features shielding, which reduces electromagnetic interference coupling to adjacent components. The unshielded substitute part may introduce or be susceptible to EMI in densely populated circuit boards. Circuit layout and application frequency bands determine whether this difference is critical.

Q: How does the DC resistance difference affect circuit performance?

A: The substitute part exhibits 1.1Ohm maximum DCR compared to 850mOhm for the original. This 250mOhm increase results in higher power dissipation at rated current (230 mA × 0.001Ohm = 0.23mW for original; 230 mA × 0.0011Ohm = 0.253mW for substitute). Impact is negligible in most applications but should be verified in power-critical designs.

Q: Are both parts suitable for high-frequency applications?

A: Both components operate at frequencies up to their self-resonant frequency (5GHz for main part, 5.5GHz for substitute). The substitute part demonstrates higher Q factor at 500MHz (13 versus 8 @ 100MHz for main part), indicating superior performance at elevated frequencies.

Q: What packaging format is available for the substitute part?

A: The 744901082 is supplied in Tape & Reel (TR) format, standard for automated assembly processes. Confirm reel specifications and minimum order quantities with your supplier.
