Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 78615/9MC is determined by the following critical parameters:

• Inductance: 10mH (exact match required)
• ET (Volt-Time): 56VµS (exact match required)
• Turns Ratio: 1CT:1CT (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Physical Dimensions: Compatible footprint within PCB layout constraints
• Height: Maximum seated height 0.250" (6.35mm) or less
• RoHS Compliance: ROHS3 Compliant (regulatory requirement)
• Moisture Sensitivity Level: MSL 1 (Unlimited) or equivalent

The 78615/9JC meets all substitution criteria as an active product offering identical electrical specifications and compatible mechanical characteristics.

Parameter Comparison

Engineering Selection Recommendations

The 78615/9JC is the direct substitute for the 78615/9MC. Both components share identical electrical specifications (10mH inductance, 56VµS ET, 1CT:1CT turns ratio) and mechanical compatibility (surface mount, 6.35mm maximum height, MSL 1). The 78615/9JC holds active product status, ensuring ongoing manufacturer support and supply chain availability.

The 78615/9JC provides an extended operating temperature range (-40°C to 85°C) compared to the 78615/9MC (0°C to 70°C), offering broader thermal performance capability. Both parts maintain ROHS3 compliance and identical export classification (EAR99). The dimensional orientation differs slightly (length and width are transposed), but both fit within the same footprint envelope for standard PCB layouts.

For applications requiring the 78615/9MC specification, the 78615/9JC is the appropriate active component selection.

Frequently Asked Questions (FAQ)

Q: Can the 78615/9JC directly replace the 78615/9MC in existing designs?

A: Yes. Both components share identical inductance (10mH), ET rating (56VµS), turns ratio (1CT:1CT), mounting type (surface mount), and maximum seated height (6.35mm). The dimensional orientation differs (length and width are transposed), but the footprint remains compatible for standard PCB layouts.

Q: What is the significance of the "Not For New Designs" status on the 78615/9MC?

A: This designation indicates the manufacturer has discontinued active support for this part number. The 78615/9JC is the active equivalent and should be used for new designs and ongoing production.

Q: Are there compliance differences between these parts?

A: Both parts are ROHS3 compliant with identical ECCN (EAR99) and HTSUS classifications (8504.31.2000). The 78615/9JC is REACH Unaffected, while the 78615/9MC is REACH Affected. Both maintain MSL 1 (Unlimited) moisture sensitivity rating.

Q: Does the extended temperature range of the 78615/9JC affect compatibility?

A: The 78615/9JC operates from -40°C to 85°C, compared to the 78615/9MC range of 0°C to 70°C. This extended range does not create incompatibility; it provides additional thermal performance margin for applications operating within the original 0°C to 70°C specification.

Q: Are there packaging or inventory considerations?

A: Both parts are supplied in tube packaging. The 78615/9JC has higher current inventory availability (2100 pcs) compared to the 78615/9MC (984 pcs), supporting supply chain continuity for production requirements.
