Substitute Part Grouping Explanation

Substitution eligibility for the 78613/1MC is determined by strict equivalence across the following electrical and mechanical parameters:

  • Inductance: Must be 2mH
  • Turns Ratio: Must be 1CT:1
  • ET (Volt-Time Product): Must be 20VµS
  • Mounting Type: Must be Surface Mount
  • Physical Footprint: Must be 0.375" L x 0.354" W (9.52mm x 9.00mm)
  • Maximum Seated Height: Must not exceed 0.250" (6.35mm)
  • Operating Temperature Range: Must support 0°C ~ 70°C minimum
  • Regulatory Compliance: Must maintain ROHS3 compliance and REACH unaffected status

The Murata 78613/1JC meets all substitution criteria and is classified as the manufacturer-recommended equivalent.

Frequently Asked Questions (FAQ)

Q: Can the 78613/1JC be used as a direct replacement for the 78613/1MC in existing designs?

A: Yes. The 78613/1JC is electrically and mechanically equivalent to the 78613/1MC. All critical parameters—inductance, turns ratio, ET product, physical dimensions, and operating temperature range—are identical. PCB layout and component placement require no modification.

Q: Why is the 78613/1MC marked "Not For New Designs"?

A: This designation indicates the part has been superseded in Murata's active product line. The 78613/1JC represents the current generation equivalent and is the recommended selection for new applications.

Q: Are there any differences in packaging or moisture sensitivity between these parts?

A: No. Both parts are supplied in tube packaging with identical moisture sensitivity level (MSL 1 - Unlimited), indicating no special moisture control is required during storage or handling.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the 78613/1MC and 78613/1JC are ROHS3 compliant and REACH unaffected, meeting equivalent regulatory standards for industrial and commercial applications.

Q: What is the physical footprint compatibility?

A: Both parts share identical surface mount dimensions of 0.375" L x 0.354" W (9.52mm x 9.00mm) with a maximum seated height of 0.250" (6.35mm), ensuring direct PCB compatibility without layout modifications.
