Substitute Part Grouping Explanation

The 506WLC2R0KG250B from American Technical Ceramics qualifies as a direct substitute based on the following critical electrical and mechanical parameters:

• Inductance Value: Both parts specify 2 µH with ±10% tolerance
• Current Rating: Both rated for 250 mA
• DC Resistance: Both specified at 1.45 Ohm (GL2R0KA7B250 nominal; 506WLC2R0KG250B maximum)
• Core Configuration: Both employ drum core, wirewound construction with iron powder material
• Shielding: Both are unshielded designs
• Physical Dimensions: Identical footprint of 0.102" L x 0.065" Sq Pyramid (2.59mm x 1.65mm)
• Mounting: Both are through-hole components with nonstandard package designation

The substitute part maintains electrical equivalence across all primary functional parameters while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

The 506WLC2R0KG250B is the qualified substitute for the obsolete GL2R0KA7B250. Selection of the substitute part is supported by:

• Product Status: The substitute maintains active manufacturing status, ensuring long-term availability and supply chain continuity
• Electrical Equivalence: All primary electrical parameters (inductance, current rating, DC resistance) are identical or within specification
• Physical Compatibility: Identical footprint and through-hole mounting configuration enable direct board-level substitution
• Compliance: The substitute part carries ROHS3 compliance certification, meeting modern regulatory requirements
• Moisture Sensitivity: Both parts share MSL 1 classification, indicating equivalent handling and storage requirements

The operating temperature range of the substitute (-40°C ~ 85°C) is narrower than the original part (-55°C ~ 125°C). Applications requiring operation below -40°C or above 85°C must be evaluated against actual circuit requirements before substitution.

Frequently Asked Questions (FAQ)

Q: Can the 506WLC2R0KG250B be used as a direct replacement for the GL2R0KA7B250?

A: Yes. Both parts share identical inductance (2 µH), current rating (250 mA), DC resistance (1.45 Ohm), core configuration, and physical dimensions. The substitute is electrically and mechanically compatible for through-hole PCB applications.

Q: What is the primary difference between these two parts?

A: The GL2R0KA7B250 is obsolete with a wider operating temperature range (-55°C ~ 125°C), while the 506WLC2R0KG250B is an active product with a narrower operating range (-40°C ~ 85°C). The substitute also carries ROHS3 compliance certification.

Q: Are there any temperature-related limitations when substituting?

A: The substitute part operates between -40°C and 85°C. If your application requires operation below -40°C or above 85°C, the narrower temperature range must be factored into the design evaluation.

Q: Do both parts have the same physical footprint?

A: Yes. Both parts measure 0.102" L x 0.065" Sq Pyramid (2.59mm x 1.65mm) and mount through-hole, enabling direct PCB substitution without layout modifications.

Q: What is the DC resistance specification for each part?

A: The GL2R0KA7B250 specifies 1.45 Ohm nominal. The 506WLC2R0KG250B specifies 1.45 Ohm maximum. Both values are equivalent for circuit design purposes.

Q: Are moisture sensitivity levels the same?

A: Yes. Both parts carry MSL 1 (Unlimited) classification, indicating identical handling, storage, and shelf-life requirements.
