Substitute Part Grouping Explanation

Substitute parts for the WHA100FE are identified based on electrical and mechanical parameter equivalence. The substitution criteria are:

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

The WHA100FET is classified as a direct manufacturer substitute, differing only in packaging configuration (Cut Tape versus standard packaging).

Parameter Comparison

Engineering Selection Recommendations

Both WHA100FE and WHA100FET are active production parts from Ohmite with identical electrical and mechanical specifications. Selection between these parts should be based on packaging requirements and inventory availability. The WHA100FET offers significantly higher stock availability (6072 units) in Cut Tape packaging, suitable for automated assembly processes. The WHA100FE is available in standard packaging with 621 units in stock. Both parts maintain ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for industrial and commercial applications.

Frequently Asked Questions (FAQ)

Q: Can WHA100FET be used as a direct replacement for WHA100FE?

A: Yes. Both parts are electrically and mechanically identical, with matching resistance, tolerance, power rating, temperature coefficient, and operating temperature range. The only difference is packaging configuration (Cut Tape versus standard).

Q: What is the significance of the packaging difference between WHA100FE and WHA100FET?

A: WHA100FE uses standard packaging, while WHA100FET uses Cut Tape (CT) packaging. Cut Tape packaging is optimized for automated pick-and-place assembly equipment. Standard packaging is suitable for manual assembly or bulk handling. Both formats contain the same component.

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

A: No. Both WHA100FE and WHA100FET carry identical RoHS3 compliance, REACH unaffected status, and EAR99 ECCN classification.

Q: Which part should be selected for high-volume production?

A: WHA100FET in Cut Tape packaging is recommended for high-volume automated assembly due to superior inventory availability (6072 units) and compatibility with standard tape-and-reel handling systems.

Q: Are the physical dimensions identical between WHA100FE and WHA100FET?

A: Yes. Both parts have identical axial dimensions of 0.100" diameter by 0.200" length (2.54mm x 5.08mm), ensuring mechanical compatibility in PCB layouts and through-hole applications.
