Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DA102MC is determined by the following critical parameters:

• Inductance Value: 3.9mH (exact match required)
• Turns Ratio: 1:1 (exact match required)
• ET (Volt-Time): 20VµS (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Physical Dimensions: 0.354" L x 0.375" W, 0.250" max height (exact match required)
• Base Product Number: DA100 series (same family)

The DA102JC qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. Both components share identical inductance, turns ratio, volt-time product, mounting configuration, and physical footprint.

Parameter Comparison

Engineering Selection Recommendations

The DA102MC and DA102JC are electrically and mechanically equivalent pulse transformers. Selection between these components should be based on the following factors:

DA102JC Advantages: Active product status ensures ongoing manufacturer support and availability. Extended operating temperature range (-40°C ~ 85°C) provides broader thermal performance envelope compared to DA102MC (0°C ~ 70°C). ROHS3 compliance maintained.

DA102MC Considerations: Not For New Designs status indicates this component is in end-of-life phase. Existing inventory of 1,713 pieces may be available for legacy system support only.

For applications requiring new component procurement or long-term supply assurance, DA102JC is the appropriate selection. For legacy system maintenance where DA102MC inventory exists, direct substitution is electrically and mechanically valid.

Frequently Asked Questions (FAQ)

Q: Can DA102JC directly replace DA102MC in existing designs? A: Yes. Both components share identical inductance (3.9mH), turns ratio (1:1), volt-time product (20VµS), mounting type (surface mount), and physical dimensions (0.354" L x 0.375" W x 0.250" max height). Electrical and mechanical compatibility is complete.

Q: What is the difference between DA102MC and DA102JC? A: The primary differences are product lifecycle status and operating temperature range. DA102JC is an active product with extended temperature range (-40°C ~ 85°C) versus DA102MC (0°C ~ 70°C). Both maintain ROHS3 compliance and identical core specifications.

Q: Why is DA102MC marked "Not For New Designs"? A: This designation indicates the component has been superseded in the manufacturer's product line. DA102JC represents the current active equivalent within the DA100 series family.

Q: Are there any packaging differences between these parts? A: Both components use surface mount packaging with identical physical footprints and height specifications. No PCB layout modifications are required for substitution.

Q: What compliance certifications apply to both parts? A: Both DA102MC and DA102JC are ROHS3 compliant and carry EAR99 ECCN classification. HTSUS code 8504.31.2000 applies to both components.
