Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the WNA100FE is determined by strict equivalence across the following critical parameters:

• Resistance value: 100 Ohms
• Tolerance: ±1%
• Power rating: 0.5W (1/2W)
• Composition: Wirewound
• Non-inductive feature requirement
• Temperature coefficient: ±20ppm/°C
• Operating temperature range: -55°C to 150°C
• Package configuration: Axial
• Physical dimensions: 0.100" Dia x 0.200" L (2.54mm x 5.08mm)
• Compliance: ROHS3 Compliant

The WNA100FET qualifies as a direct substitute based on identical electrical specifications and mechanical compatibility. The primary distinction is packaging format (Cut Tape versus standard packaging).

Parameter Comparison

Engineering Selection Recommendations

Both WNA100FE and WNA100FET are Active status components manufactured by Ohmite within the WN series. Selection between these parts is based on packaging and supply chain requirements rather than electrical or mechanical differences.

WNA100FE is suitable for standard procurement workflows and general inventory management. WNA100FET, supplied in Cut Tape (CT) packaging, is appropriate for automated assembly processes and high-volume production environments where tape-and-reel or cut tape formats are required.

Both parts maintain ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for industrial and commercial applications. No electrical performance degradation occurs when substituting between these parts.

Frequently Asked Questions (FAQ)

Q: Can WNA100FET replace WNA100FE in existing designs? A: Yes. Both parts are electrically and mechanically identical. The WNA100FET differs only in packaging format (Cut Tape). No circuit redesign or validation is required.

Q: What is the difference between the two part numbers? A: The primary difference is packaging. WNA100FE uses standard packaging, while WNA100FET is supplied in Cut Tape format. Electrical specifications, physical dimensions, and performance characteristics are identical.

Q: Are there any compliance or regulatory differences? A: No. Both parts carry identical ROHS3 compliance and REACH unaffected status. They meet the same regulatory requirements.

Q: Which part should be selected for automated assembly? A: WNA100FET in Cut Tape packaging is optimized for automated pick-and-place assembly systems. WNA100FE is suitable for manual assembly or standard procurement workflows.

Q: Do these parts have identical temperature performance? A: Yes. Both parts operate across -55°C to 150°C with ±20ppm/°C temperature coefficient. Thermal performance is identical.
