Substitute Part Grouping Explanation

Substitution eligibility for the 78615/2MC is determined by strict equivalence across the following critical parameters:

• Inductance Value: 500µH (exact match required)
• ET (Volt-Time) Rating: 10VµS (exact match required)
• Turns Ratio Configuration: 1CT:1CT (exact match required)
• Mounting Technology: Surface Mount (exact match required)
• Physical Dimensions: 0.375" L x 0.354" W, maximum height 0.250" (exact match required)
• Operating Temperature Range: 0°C ~ 70°C (exact match required)
• Regulatory Compliance: ROHS3 Compliant, MSL 1 (Unlimited)

The 78615/2JC meets all substitution criteria as a direct equivalent to the 78615/2MC, maintaining identical electrical specifications and mechanical form factor while offering active product status and improved inventory availability.
