Substitute Part Grouping Explanation

Substitution eligibility for the WNA150FE is determined by strict equivalence across the following critical parameters:

• Resistance value: 150 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 through-hole
• Physical dimensions: 0.100" Dia × 0.200" L
• Number of terminations: 2

The WNA150FET qualifies as a direct substitute because it maintains identical electrical and mechanical specifications. The primary difference is packaging format (Tape & Reel versus bulk) and inventory availability, which do not affect functional performance or circuit compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both WNA150FE and WNA150FET are active production components from Ohmite's WN series and maintain full compliance with RoHS and export control classifications. Selection between these parts should be based on procurement and assembly requirements:

The WNA150FE is suitable for applications where bulk packaging is acceptable and inventory management favors standard packaging formats. The WNA150FET is appropriate for automated assembly processes requiring tape and reel packaging, offering higher inventory availability (3928 pieces in stock versus 981 pieces).

Both parts are electrically and mechanically interchangeable in circuit applications. No design modifications or re-qualification are required when substituting between these part numbers.

Frequently Asked Questions (FAQ)

Q: Can WNA150FET be used as a direct replacement for WNA150FE in production assemblies?

A: Yes. The WNA150FET is a direct functional equivalent. All electrical parameters, mechanical dimensions, and performance characteristics are identical. The only difference is the packaging format (Tape & Reel versus bulk). No circuit modifications or testing are required.

Q: What is the difference between WNA150FE and WNA150FET?

A: The primary difference is packaging. WNA150FE is supplied in bulk packaging, while WNA150FET is supplied in Tape & Reel format. This affects handling, storage, and automated assembly compatibility but does not impact electrical or mechanical performance.

Q: Are there any compliance or certification differences between these parts?

A: Both parts are RoHS compliant and classified as EAR99 for export control purposes. Minor variations in RoHS status designation (ROHS3 Compliant versus RoHS Compliant) reflect different certification documentation but do not indicate functional differences.

Q: Which part should be selected for new designs?

A: Either part is suitable for new designs. Selection should be based on procurement logistics and assembly process requirements. Tape & Reel packaging (WNA150FET) is typically preferred for high-volume automated assembly, while bulk packaging (WNA150FE) may be suitable for lower-volume or manual assembly operations.

Q: Are the physical dimensions identical between WNA150FE and WNA150FET?

A: Yes. Both parts have identical axial dimensions of 0.100" diameter × 0.200" length (2.54mm × 5.08mm). They are mechanically interchangeable on PCBs and in through-hole applications.
