Substitute Part Grouping Explanation

Substitute parts for the 13FR050 are identified based on strict equivalence across all critical electrical and mechanical parameters. The substitution criteria are:

• Resistance value: 50 mOhms
• Tolerance: ±1%
• Power rating: 3W
• Composition: Metal Element
• Features: Current Sense, Non-Inductive
• Temperature coefficient: ±50ppm/°C
• Operating temperature range: -55°C to 275°C
• Package: Axial
• Physical dimensions: 0.205" Dia × 0.571" L (5.20mm × 14.50mm)
• Terminations: 2
• Series: 10

The 13FR050E meets all these criteria and is classified as a direct manufacturer equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the 13FR050 and 13FR050E are Active status components from Ohmite with identical electrical and mechanical specifications. The primary distinction is RoHS compliance status: the 13FR050E is ROHS3 Compliant, while the 13FR050 is RoHS non-compliant. Both components share identical REACH and ECCN classifications. Selection between these parts should be based on regulatory requirements and compliance mandates applicable to the end application.

Frequently Asked Questions (FAQ)

Q: Are the 13FR050 and 13FR050E electrically interchangeable?

A: Yes. Both parts have identical resistance (50 mOhms), tolerance (±1%), power rating (3W), temperature coefficient (±50ppm/°C), and operating temperature range (-55°C to 275°C).

Q: What is the difference between 13FR050 and 13FR050E?

A: The primary difference is packaging and RoHS compliance. The 13FR050E is ROHS3 Compliant with Bulk packaging, while the 13FR050 is RoHS non-compliant. All electrical and mechanical parameters are identical.

Q: Can I use 13FR050E as a direct replacement for 13FR050?

A: Yes, provided your application requirements permit ROHS3 Compliant components. The parts are mechanically and electrically equivalent.

Q: Are these parts suitable for PCB assembly?

A: Both parts are through-hole axial components with identical physical dimensions (0.205" Dia × 0.571" L). They are compatible with standard through-hole assembly processes.

Q: What applications require these current sense resistors?

A: These 50 mOhm resistors are designed for current sensing circuits. The non-inductive metal element construction and ±1% tolerance support precision current measurement applications across the -55°C to 275°C operating range.
