Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELJ-RF82NGFB is determined by the following critical parameters:

• Inductance Value: Must be 82 nH to maintain circuit performance
• Package / Case: Must be 0402 (1005 Metric) for PCB footprint compatibility
• Mounting Type: Must be Surface Mount for assembly compatibility
• Shielding Type: Must be Unshielded to match electromagnetic characteristics
• Current Rating: Must meet or exceed 110 mA minimum requirement
• DC Resistance: Should be comparable to 4.5Ohm maximum to minimize losses

The MLG1005S82NHT000 from TDK Corporation meets all critical substitution criteria while offering improved electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The MLG1005S82NHT000 is a direct functional substitute for the obsolete ELJ-RF82NGFB. Both components share identical inductance values, package dimensions, and unshielded multilayer construction. The TDK alternative provides superior electrical performance with lower DC resistance (1.6Ohm versus 4.5Ohm maximum) and higher current rating capability (200 mA versus 110 mA), resulting in reduced power dissipation and improved thermal margin in the application circuit.

The MLG1005S82NHT000 maintains active product status with ROHS3 compliance certification, ensuring long-term availability and regulatory alignment. The extended operating temperature range (-55°C to 125°C versus -20°C to 85°C) provides additional design flexibility for applications requiring broader thermal performance.

Frequently Asked Questions (FAQ)

Q: Can the MLG1005S82NHT000 be used as a direct replacement for the ELJ-RF82NGFB?

A: Yes. Both components have identical inductance values (82 nH), package dimensions (0402 / 1005 Metric), and unshielded construction. The TDK part is electrically compatible and offers improved performance characteristics.

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

A: The primary differences are DC resistance (1.6Ohm versus 4.5Ohm maximum), current rating (200 mA versus 110 mA), and operating temperature range (-55°C to 125°C versus -20°C to 85°C). The TDK component provides superior electrical performance with lower losses and higher current capacity.

Q: Will the PCB footprint remain the same?

A: Yes. Both inductors use the 0402 (1005 Metric) surface mount package with identical physical dimensions (0.039" L x 0.020" W / 1.00mm x 0.50mm) and maximum seated height (0.022" / 0.55mm). No PCB layout modifications are required.

Q: Is the MLG1005S82NHT000 available in the same packaging format?

A: The MLG1005S82NHT000 is supplied in Tape & Reel (TR) format. Verify packaging requirements for your procurement process.

Q: What is the tolerance difference between these parts?

A: The ELJ-RF82NGFB has ±2% tolerance while the MLG1005S82NHT000 has ±3% tolerance. Both tolerances are suitable for most RF and general-purpose applications at 82 nH inductance.

Q: Are there any compliance or regulatory considerations?

A: The MLG1005S82NHT000 is ROHS3 compliant with REACH unaffected status. Both components have MSL 1 (Unlimited) moisture sensitivity rating and EAR99 export classification.
