Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the WLBR005FE are identified based on strict equivalence across all critical electrical and mechanical parameters. The substitution criteria are:

• Resistance value: 5 mOhms
• Tolerance: ±1%
• Power rating: 1W
• Composition: Wirewound
• Package: Axial
• Physical dimensions: 0.130" Dia x 0.276" L (3.30mm x 7.00mm)
• Temperature coefficient: ±300ppm/°C
• Features: Current Sense, Moisture Resistant
• Compliance: ROHS3 Compliant

The WLBR005FET meets all these criteria and is classified as a direct substitute. The only difference is packaging format (Cut Tape vs. standard packaging), which does not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both WLBR005FE and WLBR005FET are Active status components manufactured by Ohmite within the WL series. Both parts are ROHS3 Compliant and meet identical electrical specifications for resistance, tolerance, power rating, and temperature coefficient. The parts are mechanically and electrically interchangeable in all applications.

Selection between these parts should be based on packaging requirements and inventory availability. The WLBR005FET is supplied in Cut Tape format with higher inventory availability (3074 units), while the WLBR005FE is supplied in standard packaging with 1133 units available. Both formats are suitable for through-hole axial mounting applications.

Frequently Asked Questions (FAQ)

Q: Can WLBR005FET be used as a direct replacement for WLBR005FE?

A: Yes. Both parts are electrically and mechanically identical. The only difference is the packaging format (Cut Tape vs. standard). They are functionally interchangeable in all circuit applications.

Q: What is the difference between the packaging formats?

A: WLBR005FE uses standard packaging, while WLBR005FET is supplied in Cut Tape (CT) format. Cut Tape packaging is designed for automated assembly processes, while standard packaging is suitable for manual or mixed assembly environments. The component itself is identical.

Q: Are both parts RoHS compliant?

A: Yes. Both WLBR005FE and WLBR005FET are ROHS3 Compliant.

Q: What are the key parameters that define substitutability for this resistor?

A: Substitutability is determined by: resistance value (5 mOhms), tolerance (±1%), power rating (1W), composition (Wirewound), package type (Axial), physical dimensions (0.130" Dia x 0.276" L), temperature coefficient (±300ppm/°C), and features (Current Sense, Moisture Resistant).

Q: Can I use these parts in high-temperature applications?

A: The operating temperature range is not specified in the provided data. Consult the manufacturer's datasheet for specific temperature operating limits and derating curves.
