Key Parameters

Substitute Part Grouping Explanation

The WNC200FET qualifies as a parametric equivalent to the WHC200FET based on the following matching electrical and mechanical specifications:

• Resistance value: 200 Ohms
• Tolerance: ±1%
• Power rating: 2W
• Composition: Wirewound
• Package type: Axial
• Temperature coefficient: ±20ppm/°C
• Operating temperature range: -55°C ~ 150°C
• Physical dimensions: 0.180" Dia x 0.449" L (4.57mm x 11.40mm)
• Number of terminations: 2

The primary distinction between these parts is the packaging format (Cut Tape vs. Tape & Reel) and the addition of non-inductive winding in the WNC200FET series. Both parts maintain identical electrical performance and mechanical fit within the specified parameter constraints.

Parameter Comparison

Engineering Selection Recommendations

Both the WHC200FET and WNC200FET are Active products from Ohmite with full RoHS compliance. Selection between these parts is determined by packaging requirements and application-specific needs:

The WHC200FET in Cut Tape packaging is suitable for lower-volume applications and manual assembly processes. The WNC200FET in Tape & Reel format is optimized for high-volume automated assembly operations. The non-inductive winding feature of the WNC200FET provides reduced parasitic inductance, beneficial in high-frequency or precision signal applications where inductive effects must be minimized. Both parts maintain identical electrical performance across the specified operating temperature range and meet all regulatory compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can WNC200FET replace WHC200FET in existing designs? A: Yes. Both parts share identical electrical specifications (200 Ohms ±1%, 2W, ±20ppm/°C) and mechanical dimensions (0.180" Dia x 0.449" L). The primary difference is packaging format and the non-inductive winding feature of the WNC200FET.

Q: What is the difference between Cut Tape and Tape & Reel packaging? A: Cut Tape (CT) packaging is supplied in individual strips suitable for manual handling and lower-volume applications. Tape & Reel (TR) packaging is wound on reels for automated pick-and-place assembly systems in high-volume manufacturing.

Q: Does the non-inductive feature of WNC200FET affect compatibility? A: No. Non-inductive winding reduces parasitic inductance without changing the resistive value or power rating. This feature is beneficial in high-frequency circuits but does not prevent use in standard applications.

Q: Are both parts RoHS compliant? A: Yes. WHC200FET is ROHS3 Compliant and WNC200FET is RoHS Compliant. Both meet regulatory requirements for hazardous substance restrictions.

Q: What is the temperature coefficient significance? A: The ±20ppm/°C temperature coefficient indicates resistance change per degree Celsius. Both parts maintain this specification across the -55°C ~ 150°C operating range, ensuring stable performance in temperature-variable environments.
