Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 13FR080 are qualified based on matching the following critical parameters:

• Resistance value: 80 mOhms
• Tolerance: ±1%
• Power rating: 3W
• Composition: Metal Element
• Package type: Axial
• Physical dimensions: 0.205" Dia x 0.571" L (5.20mm x 14.50mm)
• Temperature coefficient: ±50ppm/°C
• Operating temperature range: -55°C ~ 275°C
• Number of terminations: 2

The identified substitutes (13FR080E and 13FR080E-B) maintain identical electrical specifications and mechanical form factors, differing only in packaging configuration and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

All three part numbers (13FR080, 13FR080E, and 13FR080E-B) are electrically and mechanically equivalent for current sensing applications requiring 80 milliohm resistance at 3 watts with ±1% tolerance.

The 13FR080E offers ROHS3 compliance and is available in bulk packaging, making it suitable for applications subject to RoHS3 regulatory requirements.

The 13FR080E-B provides an alternative bulk packaging option with MSL Level 1 (Unlimited) moisture sensitivity rating. REACH compliance status for this variant is vendor-defined.

Selection between these parts should be based on specific regulatory compliance requirements, packaging needs, and supply chain availability rather than electrical performance, as all variants maintain identical functional specifications.

Frequently Asked Questions (FAQ)

Q: Can 13FR080E be used as a direct replacement for 13FR080?

A: Yes. Both parts share identical electrical specifications (80 mOhms, ±1%, 3W), composition (Metal Element), temperature characteristics (±50ppm/°C, -55°C to 275°C), and physical dimensions (0.205" Dia x 0.571" L). The primary difference is packaging configuration and RoHS3 compliance status of the 13FR080E.

Q: What is the difference between 13FR080E and 13FR080E-B?

A: Both parts are electrically and mechanically identical. The 13FR080E-B specifies MSL Level 1 (Unlimited) moisture sensitivity, while the 13FR080E does not specify MSL. REACH compliance status differs between the two variants.

Q: Are all three parts suitable for current sensing applications?

A: Yes. All three variants feature metal element composition and non-inductive construction (where specified), making them appropriate for current sensing circuits within the specified power and temperature parameters.

Q: Does packaging type affect electrical performance?

A: No. Both variants use identical axial through-hole packaging with the same physical dimensions. Packaging differences relate to supplier configuration (tape and reel versus bulk) and do not affect electrical characteristics.

Q: Which part should be selected for RoHS3-compliant applications?

A: The 13FR080E is specified as ROHS3 Compliant. The 13FR080 is RoHS non-compliant, and the 13FR080E-B does not specify RoHS status.
