SWT-1.02-17 Equivalent & Substitute Parts

Part Overview

The SWT-1.02-17 is a 17 µH unshielded toroidal inductor manufactured by Amgis, LLC, rated for 1.02 A with 100mOhm DC resistance. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing design support and procurement continuity. Equivalent parts must maintain the core electrical specifications while accommodating potential differences in mechanical packaging and terminal configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SWT-1.02-17 is determined by strict equivalence in the following parameters:

• Inductance Value: 17 µH (exact match required)
• Current Rating: 1.02 A (minimum threshold)
• DC Resistance: 100mOhm (exact match required)
• Tolerance: ±20% (exact match required)
• Mounting Type: Through Hole (required for PCB compatibility)
• Operating Temperature Range: Must encompass or exceed -40°C ~ 125°C

Variations permitted in substitute selection include shielding configuration, terminal orientation (horizontal vs. vertical), package case style, and physical dimensions, provided the core electrical parameters remain unchanged. The inductance test frequency of 10 kHz serves as the reference measurement standard across all candidates.

Parameter Comparison

Engineering Selection Recommendations

SH150T-1.02-17 (Amgis, LLC): This substitute maintains identical electrical specifications and operating temperature range as the SWT-1.02-17. Both components are manufactured by Amgis, LLC and share the same series heritage. The primary difference is terminal configuration (corner terminals vs. open terminals) and slightly larger physical dimensions. This part is currently active in production, ensuring long-term availability. RoHS3 and REACH compliance are maintained.

PE-53816NL (Pulse Electronics): This substitute meets all core electrical requirements and extends the operating temperature range to -40°C ~ 130°C. The key distinction is shielded construction versus the unshielded design of the original part. Shielding may introduce electromagnetic isolation benefits in noise-sensitive applications but requires verification that the circuit design accommodates this change. The part is active and fully compliant with RoHS3 and REACH standards. Physical dimensions differ, requiring PCB layout validation.

Both substitutes are active products with established supply chains, addressing the obsolescence status of the SWT-1.02-17.

Frequently Asked Questions (FAQ)

Q: Can SH150T-1.02-17 be used as a direct replacement for SWT-1.02-17?

A: Yes, from an electrical standpoint. Both parts share identical inductance (17 µH), current rating (1.02 A), DC resistance (100mOhm), and tolerance (±20%). The terminal configuration differs (corner terminals vs. open terminals), and physical dimensions are larger. PCB layout must accommodate the increased footprint (11.00mm x 11.20mm vs. 8.60mm x 8.60mm).

Q: What is the impact of shielding in the PE-53816NL substitute?

A: The PE-53816NL features shielded construction, whereas the SWT-1.02-17 is unshielded. Shielding reduces electromagnetic radiation and susceptibility to external fields. If the original circuit was designed around unshielded characteristics, shielding may alter circuit behavior. Electrical parameters (inductance, current rating, DCR) remain identical, but electromagnetic coupling effects differ.

Q: Are all three parts RoHS and REACH compliant?

A: Yes. SWT-1.02-17, SH150T-1.02-17, and PE-53816NL are all ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: Does the extended temperature range of PE-53816NL (-40°C ~ 130°C) provide an advantage?

A: The PE-53816NL operates 5°C higher at the upper limit (130°C vs. 125°C). This provides marginal additional thermal headroom but does not constitute a functional advantage unless the application specifically requires operation above 125°C.

Q: What are the physical footprint differences?

A: SWT-1.02-17: 8.60mm x 8.60mm x 7.30mm (height). SH150T-1.02-17: 11.00mm x 11.20mm x 7.10mm (height). PE-53816NL: 10.16mm x 10.16mm x 7.62mm (height). All three are through-hole mounted but with different terminal orientations and body dimensions.

Q: Which substitute offers the best procurement continuity?

A: Both SH150T-1.02-17 and PE-53816NL are active products with current inventory. SH150T-1.02-17 maintains Amgis, LLC manufacturing, while PE-53816NL provides a multi-source alternative through Pulse Electronics. Selection depends on supply chain strategy and PCB layout constraints.
