Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 78602/2MC is determined by strict equivalence across the following critical parameters:

• Inductance Value: 500µH (exact match required)
• Turns Ratio Configuration: 1:1:1 (exact match required)
• ET Product: 10VµS (exact match required)
• Transformer Classification: General Purpose pulse transformer
• Mounting Technology: Surface mount toroidal package
• Compliance Standards: ROHS3 compliance and EAR99 export classification

The 78602/2JC meets all substitution criteria as a manufacturer-recommended equivalent. Both components share identical electrical specifications, compliance certifications, and functional characteristics within their respective operating environments.

Parameter Comparison

Engineering Selection Recommendations

The 78602/2JC is the manufacturer-designated substitute for the 78602/2MC. Both components are ROHS3 compliant and carry identical EAR99 export classifications, ensuring regulatory consistency across supply chain transitions.

The 78602/2JC offers an extended operating temperature range (-40°C to 85°C) compared to the original part (0°C to 70°C), providing greater thermal flexibility for applications requiring wider environmental tolerance. The active product status of the 78602/2JC ensures ongoing manufacturer support, availability, and compliance with current industry standards.

Dimensional compatibility is maintained across both parts, with footprint dimensions remaining functionally equivalent for surface mount PCB layouts. The slight dimensional notation difference (L × W orientation) reflects standard documentation conventions and does not affect mechanical or electrical interchangeability.

Frequently Asked Questions (FAQ)

Q: Can the 78602/2JC be used as a direct replacement for the 78602/2MC in existing designs?

A: Yes. Both components share identical electrical specifications (500µH inductance, 1:1:1 turns ratio, 10VµS ET product), transformer classification, and surface mount package dimensions. The 78602/2JC is the manufacturer-recommended equivalent.

Q: What is the significance of the "Not For New Designs" status on the 78602/2MC?

A: This designation indicates that Murata has discontinued active production and support for this model. New circuit designs should specify the 78602/2JC, which carries an "Active" product status and ensures long-term availability and manufacturer support.

Q: Are there any compliance or certification differences between these parts?

A: Both components are ROHS3 compliant and carry EAR99 export classifications. The 78602/2JC is REACH Unaffected, while the 78602/2MC is REACH Affected. Both meet the same regulatory requirements for industrial and commercial applications.

Q: How do the operating temperature ranges differ, and does this affect substitution?

A: The 78602/2MC operates from 0°C to 70°C, while the 78602/2JC operates from -40°C to 85°C. For applications within the 0°C to 70°C window, both parts are functionally equivalent. The 78602/2JC provides additional thermal margin for extended-range applications.

Q: Are the physical dimensions identical between these parts?

A: Both components measure 9.52mm × 9.00mm in footprint and 6.35mm maximum seated height. The dimensional notation order differs in documentation (L × W versus W × L), but the actual package dimensions are functionally equivalent for PCB layout purposes.

Q: What inventory status should be considered when selecting between these parts?

A: The 78602/2MC has 1046 pieces in stock, while the 78602/2JC has 954 pieces available. For long-term supply chain planning, the 78602/2JC is recommended due to its active product status and ongoing manufacturer commitment.
