Key Parameters

Substitute Part Grouping Explanation

Substitution of the ELJ-RF10NJF is determined by the following critical parameters:

• Inductance Value: Must be 10 nH with ±5% tolerance
• Package / Case: Must be 0402 (1005 Metric) for mechanical and electrical compatibility
• Mounting Type: Must be Surface Mount
• Shielding Configuration: Must be Unshielded
• Type: Must be Multilayer construction
• Current Rating: Substitute must meet or exceed 320 mA
• DC Resistance: Substitute must not exceed 410 mOhm maximum
• Frequency Characteristics: Q factor and self-resonant frequency should align with RF application requirements

The LQG15HN10NJ02D from Murata Electronics meets all substitution criteria and is classified as an active product with improved electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The LQG15HN10NJ02D is a direct functional substitute for the ELJ-RF10NJF. The Murata component offers superior electrical performance with lower DC resistance (290 mOhm versus 410 mOhm), higher current rating capability (500 mA versus 320 mA), and an extended operating temperature range (-55°C to 125°C versus -20°C to 85°C). The substitute maintains identical inductance value, tolerance, package dimensions, and Q factor at 100 MHz.

The LQG15HN10NJ02D is classified as an active product with ROHS3 compliance, ensuring long-term availability and regulatory alignment. The higher self-resonant frequency (3.2 GHz versus 2.8 GHz) provides additional margin for RF applications.

Frequently Asked Questions (FAQ)

Q: Can the LQG15HN10NJ02D replace the ELJ-RF10NJF in existing designs?

A: Yes. Both components share identical inductance (10 nH), tolerance (±5%), package (0402), and mounting type (surface mount). The substitute meets or exceeds all electrical specifications of the original part.

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

A: The primary differences are current rating (500 mA versus 320 mA), DC resistance (290 mOhm versus 410 mOhm), operating temperature range (-55°C to 125°C versus -20°C to 85°C), and product status (active versus obsolete). The LQG15HN10NJ02D provides improved performance across all parameters.

Q: Are the physical dimensions identical?

A: Yes. Both components are packaged in 0402 (1005 Metric) with identical length (0.039"), width (0.020"), and maximum seated height (0.022").

Q: Does the substitute have different RoHS compliance?

A: Yes. The ELJ-RF10NJF is RoHS non-compliant, while the LQG15HN10NJ02D is ROHS3 compliant, meeting current environmental regulations.

Q: Are there any frequency-related differences?

A: Both inductors maintain the same Q factor (8 @ 100MHz). The self-resonant frequency differs slightly (3.2 GHz versus 2.8 GHz), with the substitute offering higher frequency margin for RF circuit applications.
