Key Parameters

Substitute Part Grouping Explanation

The PE-67540NLT qualifies as a direct substitute for the PE-67540T based on the following critical parameters:

• Electrical Specifications: Identical DC resistance rating of 600mOhm maximum
• Functional Design: Same 4-line common mode choke configuration for signal line filtering
• Physical Form Factor: Matching surface mount package with vertical 8 gull wing configuration
• Dimensional Compatibility: Identical footprint (0.476" L x 0.602" W) and height (0.350" maximum)

The substitution is valid across these core parameters, which determine mechanical fit and electrical performance in the application circuit.

Engineering Selection Recommendations

The PE-67540NLT is the direct substitute for the obsolete PE-67540T. Selection of the PE-67540NLT is based on:

• Product Status: The PE-67540NLT maintains active product status with ongoing manufacturer support, whereas the PE-67540T is obsolete
• Compliance: The PE-67540NLT is RoHS compliant and carries improved moisture sensitivity rating (MSL 1 vs. MSL 3), providing enhanced reliability for long-term storage and field deployment
• Electrical Equivalence: Both parts maintain identical DC resistance and electrical filtering characteristics
• Physical Compatibility: Identical package footprint and height ensure direct PCB layout compatibility without redesign

Frequently Asked Questions (FAQ)

Q: Can PE-67540NLT be used as a direct replacement for PE-67540T in existing designs?

A: Yes. The PE-67540NLT is electrically and mechanically equivalent to the PE-67540T. Both components share identical DC resistance (600mOhm), 4-line configuration, surface mount package type, and physical dimensions. No circuit redesign or PCB layout modification is required.

Q: What are the key differences between PE-67540T and PE-67540NLT?

A: The primary differences are product status, compliance certifications, and packaging format. The PE-67540NLT is an active product with RoHS compliance and improved moisture sensitivity rating (MSL 1 vs. MSL 3). The PE-67540NLT is supplied in Tape & Reel packaging, while the PE-67540T was supplied in bulk packaging.

Q: Are there any electrical performance differences between these parts?

A: No. Both parts maintain identical DC resistance specifications (600mOhm maximum) and are configured as 4-line common mode chokes for signal line filtering. Electrical performance in the application circuit is equivalent.

Q: What does the MSL rating difference mean for component handling?

A: The PE-67540T carries MSL 3 (168-hour moisture sensitivity limit), while the PE-67540NLT carries MSL 1 (unlimited moisture sensitivity). MSL 1 indicates superior moisture resistance and allows extended storage without desiccant packaging requirements, reducing handling constraints during manufacturing and assembly.

Q: Is the Tape & Reel packaging of PE-67540NLT compatible with automated assembly equipment?

A: Yes. Tape & Reel (TR) packaging is the standard format for automated surface mount assembly processes. This packaging format is compatible with standard pick-and-place equipment and provides improved handling efficiency compared to bulk packaging.
