Key Parameters

Substitute Part Grouping Explanation

Substitution of the CTX25-2P is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Inductance values in both series (99.14 µH) and parallel (24.79 µH) configurations
• Current ratings: 1.4 A parallel, 700 mA series
• DC resistance specifications: 109 mOhm max parallel, 436 mOhm max series
• Tolerance: ±20%

Physical Parameters:

• Number of coils: 2
• Mounting type: Surface Mount
• Physical dimensions: 0.450" L x 0.450" W x 0.235" H
• Shielding: Unshielded

Environmental Parameters:

• Operating temperature range: -40°C to 85°C
• Moisture sensitivity level: 1

The CTX25-2P-R is a direct substitute that maintains identical electrical and mechanical specifications while differing only in packaging format (Tape & Reel versus standard packaging) and product status (Active versus Obsolete).
