Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SWS-1.50-250 is determined by the following critical parameters:

• Inductance Value: 250 µH with ±20% tolerance
• Current Rating: 1.5 A minimum
• DC Resistance: 230mOhm
• Mounting Type: Surface Mount
• Package Classification: Nonstandard toroidal form factor
• Compliance: ROHS3 and REACH requirements

The PE-53935SNL from Pulse Electronics meets all core electrical specifications. The primary difference is shielding classification: the SWS-1.50-250 is unshielded while the PE-53935SNL is shielded. Both components share identical inductance, tolerance, current rating, and DC resistance values. Physical dimensions vary slightly, and the operating temperature maximum differs by 5°C (130°C vs. 125°C).

Parameter Comparison

Engineering Selection Recommendations

Both the SWS-1.50-250 and PE-53935SNL are active production components with full ROHS3 and REACH compliance. Selection between these parts depends on application-specific requirements:

The SWS-1.50-250 is suitable for applications where unshielded operation is acceptable and the standard operating temperature ceiling of 125°C is sufficient. The PE-53935SNL provides shielded operation with extended temperature capability to 130°C, making it appropriate for applications requiring electromagnetic interference mitigation or operation at elevated temperatures. Both components maintain identical electrical performance within the specified tolerance band.

Physical footprint differences exist: the PE-53935SNL has a slightly larger lateral dimension (0.940" vs. 0.925") but lower profile height (0.400" vs. 0.506"). PCB layout constraints may influence part selection based on available mounting space.

Frequently Asked Questions (FAQ)

Q: Can PE-53935SNL directly replace SWS-1.50-250 in all applications?

A: Direct replacement is possible when the application tolerates shielded operation and the 0.015" increase in lateral dimension and 0.106" reduction in height do not create PCB layout conflicts. Electrical performance is equivalent within specified tolerances.

Q: What is the significance of shielding differences between these parts?

A: The SWS-1.50-250 is unshielded, while PE-53935SNL is shielded. Shielding reduces electromagnetic radiation and susceptibility to external interference. Applications sensitive to EMI may require the shielded variant; applications in low-noise environments may not require shielding.

Q: Are there temperature rating implications for substitution?

A: The PE-53935SNL operates to 130°C maximum versus 125°C for the SWS-1.50-250. This 5°C difference is not significant for most industrial applications but may be relevant in high-temperature environments near the upper operating limit.

Q: Do packaging differences affect component handling or assembly?

A: Both components are rated MSL 1 (Unlimited moisture sensitivity), indicating no special moisture control requirements during storage or assembly. Packaging format differs (Tape & Reel vs. Bulk), which may affect procurement and assembly line integration but not component performance.

Q: Are both parts suitable for high-reliability applications?

A: Both components meet ROHS3 and REACH compliance requirements. Product status is active for both manufacturers, indicating ongoing production support and supply chain stability.
