Substitute Part Grouping Explanation

Substitution eligibility for the 78613/9MC is determined by matching the following critical electrical and mechanical parameters:

• Inductance value: 10mH (exact match required)
• Turns ratio configuration: 1CT:1 (exact match required)
• ET product: 56VµS (exact match required)
• Mounting technology: Surface Mount (exact match required)
• Physical footprint: 0.375" L x 0.354" W, maximum height 0.250" (exact match required)
• Operating temperature range: 0°C ~ 70°C (minimum required)

The substitute part 78613/9JC meets all specified electrical and mechanical parameters, confirming direct substitution capability.

Parameter Comparison

Engineering Selection Recommendations

The 78613/9JC is the direct substitute for the 78613/9MC. Both components share identical electrical specifications (10mH inductance, 1CT:1 turns ratio, 56VµS ET product) and mechanical characteristics (surface mount footprint, 0.375" x 0.354" x 0.250" maximum dimensions).

The 78613/9JC offers two significant advantages: it maintains Active product status within Murata's current portfolio, and it carries REACH Unaffected classification compared to the REACH Affected status of the 78613/9MC. Both parts are ROHS3 compliant with MSL 1 rating, indicating no moisture sensitivity constraints during storage and handling.

Selection of the 78613/9JC is appropriate for applications requiring component continuity, supply chain stability, and regulatory compliance assurance.

Frequently Asked Questions (FAQ)

Q: Can the 78613/9JC be used as a direct replacement for the 78613/9MC in existing designs?

A: Yes. The 78613/9JC meets all electrical and mechanical specifications of the 78613/9MC, including inductance (10mH), turns ratio (1CT:1), ET product (56VµS), mounting type (surface mount), and physical dimensions (0.375" L x 0.354" W x 0.250" H maximum).

Q: What is the difference between these two part numbers?

A: The primary differences are product lifecycle status and regulatory classification. The 78613/9MC is designated "Not For New Designs" and carries REACH Affected status.
