Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DA101MC is determined by strict equivalence across the following critical parameters:

• Inductance value of 2.06mH
• ET (Volt-Time) specification of 15VµS
• Turns ratio of 1:1 (primary to secondary)
• Surface mount mounting configuration
• Physical dimensions: 0.354" L x 0.375" W (9.00mm x 9.52mm)
• Maximum seated height of 0.250" (6.35mm)
• ROHS3 compliance

The DA101JC meets all these criteria and is qualified as a direct substitute. Both parts share the same base product number (DA101) and maintain identical electrical and mechanical specifications, ensuring functional interchangeability in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

The DA101JC is the qualified substitute for the DA101MC. Both components are manufactured by Murata Power Solutions Inc. and maintain identical electrical specifications and physical dimensions. The DA101JC offers the following advantages:

• Active product status, ensuring continued availability and manufacturer support
• Extended operating temperature range (-40°C to 85°C versus 0°C to 70°C), providing greater thermal flexibility
• ROHS3 compliance maintained across both parts
• Identical inductance, ET specification, turns ratio, and mounting configuration

For new circuit designs or component refresh cycles, the DA101JC is the appropriate selection. For existing applications currently using the DA101MC, the DA101JC provides direct functional replacement with enhanced product lifecycle status.

Frequently Asked Questions (FAQ)

Q: Can the DA101JC replace the DA101MC in existing applications?

A: Yes. The DA101JC is electrically and mechanically equivalent to the DA101MC. Both components share identical inductance (2.06mH), ET specification (15VµS), turns ratio (1:1), and physical dimensions. Surface mount footprint compatibility is maintained.

Q: What is the difference between the DA101MC and DA101JC?

A: The primary differences are product status and operating temperature range. The DA101MC is classified as "Not For New Designs" with an operating range of 0°C to 70°C. The DA101JC is an active product with an extended operating range of -40°C to 85°C. Packaging differs (Box versus Tube), but electrical and mechanical specifications are identical.

Q: Why is the DA101MC marked "Not For New Designs"?

A: This designation indicates the component has been superseded in the manufacturer's product line. The DA101JC represents the current active equivalent and should be used for new designs and component procurement.

Q: Are there any compatibility concerns when switching from DA101MC to DA101JC?

A: No compatibility concerns exist. The components are functionally interchangeable with identical electrical parameters and surface mount dimensions. The DA101JC's extended temperature range provides additional operational margin without requiring circuit modifications.

Q: Does packaging type affect electrical performance?

A: No. The DA101MC (Box packaging) and DA101JC (Tube packaging) have identical electrical specifications. Packaging type affects only handling, storage, and logistics considerations, not component performance or circuit compatibility.
