T7015T Pulse Transformer Equivalent & Substitute Parts

Part Overview

The T7015T is a 20mH pulse transformer manufactured by Pulse Electronics, configured with 1CT:2CT turns ratio for both transmitter and receiver applications in surface mount packages. This component is classified as obsolete, making identification of suitable alternatives essential for ongoing production and maintenance applications. The T7015T's discontinuation necessitates evaluation of compatible substitute components that maintain electrical and mechanical compatibility with existing designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the T7015T is determined by strict alignment of the following critical parameters:

• Inductance: 20mH (exact match required)
• Turns Ratio: 1:2CT primary to secondary configuration for both transmitter and receiver windings
• Mounting Type: Surface mount package only
• Physical Dimensions: 0.675" L x 0.456" W (17.15mm x 11.58mm) footprint and 0.340" (8.64mm) maximum seated height
• Operating Temperature Range: 0°C ~ 70°C
• Moisture Sensitivity Level: MSL 3 (168 Hours)

The T7015NLT meets all substitution criteria as a direct equivalent from the same manufacturer with identical electrical specifications and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The T7015NLT is the direct substitute for the obsolete T7015T. Both components are manufactured by Pulse Electronics and share identical electrical and mechanical specifications, including 20mH inductance, 1:2CT turns ratio configuration, surface mount footprint, and operating temperature range.

The T7015NLT offers the additional advantage of active product status, ensuring continued availability and supply chain reliability. The T7015NLT also provides ROHS3 compliance, addressing regulatory requirements that may apply to new designs or production runs. Both components maintain equivalent MSL 3 moisture sensitivity specifications.

Frequently Asked Questions (FAQ)

Q: Can the T7015NLT directly replace the T7015T in existing designs?

A: Yes. The T7015NLT is a direct substitute with identical inductance (20mH), turns ratio (1:2CT), mounting type (surface mount), physical dimensions (0.675" L x 0.456" W, 0.340" max height), and operating temperature range (0°C ~ 70°C). No circuit modifications are required.

Q: What is the primary difference between T7015T and T7015NLT?

A: The T7015T is obsolete, while the T7015NLT maintains active product status. The T7015NLT also provides ROHS3 compliance compared to the non-compliant status of the T7015T. Electrical and mechanical specifications are identical.

Q: Are there packaging differences between these parts?

A: The T7015NLT is supplied in Tape & Reel (TR) packaging, which is standard for surface mount components in production environments. The T7015T packaging specification was not provided in the original documentation.

Q: Do both parts have the same moisture sensitivity requirements?

A: Yes. Both the T7015T and T7015NLT are classified as MSL 3 with a 168-hour floor life specification. Identical moisture handling and storage protocols apply to both components.

Q: Is the T7015NLT suitable for designs requiring RoHS compliance?

A: Yes. The T7015NLT is ROHS3 compliant, making it suitable for applications and markets requiring RoHS certification. The original T7015T does not meet RoHS requirements.
