Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the T7015 is determined by the following critical parameters:

• Inductance: 20mH (exact match required)
• Turns Ratio: 1:2CT primary to secondary configuration (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Physical Dimensions: 0.675" L x 0.456" W and 0.340" maximum seated height (exact match required)
• Operating Temperature Range: 0°C ~ 70°C (exact match required)
• Moisture Sensitivity Level: MSL 3 (168 Hours) (exact match required)

The T7015NL qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. The primary distinction is product status: T7015NL is active production, whereas T7015 is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The T7015NL is the direct substitute for the obsolete T7015. Both components share identical electrical specifications (20mH inductance, 1:2CT turns ratio) and mechanical dimensions (0.675" L x 0.456" W, 0.340" maximum height). Both operate within the 0°C to 70°C temperature range and maintain MSL 3 classification.

A significant advantage of T7015NL is its active production status and ROHS3 compliance, compared to the T7015's obsolete status and RoHS non-compliance. For new designs or production continuity, T7015NL is the appropriate selection. The T7015NL is classified as an Isolation and Data Interface (Encapsulated) transformer, providing enhanced functional capability while maintaining full electrical and mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can T7015NL be used as a direct replacement for T7015 in existing designs?

A: Yes. The T7015NL matches all critical electrical and mechanical parameters: 20mH inductance, 1:2CT turns ratio, surface mount configuration, identical physical dimensions (0.675" L x 0.456" W, 0.340" height), and 0°C to 70°C operating temperature range. No circuit modifications are required.

Q: What is the primary difference between T7015 and T7015NL?

A: The T7015 is obsolete with RoHS non-compliance status. The T7015NL is in active production and ROHS3 compliant. Functionally, T7015NL is specified as an Isolation and Data Interface (Encapsulated) transformer, whereas T7015 lacks this detailed classification.

Q: Are there any packaging differences between these parts?

A: The T7015 is specified with "-" packaging notation. The T7015NL is supplied in Tube packaging. Both components are surface mount with identical footprints and dimensions, ensuring PCB compatibility.

Q: What does MSL 3 (168 Hours) mean for these transformers?

A: Moisture Sensitivity Level 3 indicates the component requires controlled storage conditions. The 168-hour specification means the component can be exposed to 30°C and 85% relative humidity for up to 168 hours before soldering without baking.

Q: Is the T7015NL suitable for new production designs?

A: Yes. The T7015NL's active production status and ROHS3 compliance make it the appropriate choice for new designs. It provides full electrical and mechanical compatibility with legacy T7015 designs while offering improved regulatory compliance.
