Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Ohmite 13FR070 is determined by the following critical parameters:

• Resistance value: 70 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 type: Axial
• Physical dimensions: 0.205" Dia × 0.571" L (5.20mm × 14.50mm)
• Number of terminations: 2

The substitute part 13FR070E meets all these criteria and is manufactured by Ohmite under the same Series 10 product line. The primary difference is packaging configuration (Bulk versus standard packaging) and RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

Both the 13FR070 and 13FR070E are active production parts manufactured by Ohmite with identical electrical and mechanical specifications. Selection between these parts should be based on the following factors:

The 13FR070E offers ROHS3 compliance, making it suitable for applications subject to RoHS regulations. The 13FR070 is RoHS non-compliant and should be selected only when RoHS compliance is not a requirement.

Both parts carry REACH Unaffected status and are classified under ECCN EAR99 and HTSUS 8533.21.0090. Packaging configuration differs between the two variants: the 13FR070 uses standard packaging while the 13FR070E is supplied in bulk packaging. This distinction may affect procurement workflows and inventory management but does not impact electrical or mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can the 13FR070E directly replace the 13FR070 in existing designs?

A: Yes. Both parts are electrically and mechanically identical. The 13FR070E can be used as a direct substitute. The primary consideration is RoHS compliance requirement; if your application requires ROHS3 compliance, the 13FR070E is the appropriate choice.

Q: What is the difference between the 13FR070 and 13FR070E?

A: The parts are functionally identical with the same resistance value (70 mOhms), tolerance (±1%), power rating (3W), temperature coefficient (±50ppm/°C), operating temperature range (-55°C to 275°C), and physical dimensions (0.205" Dia × 0.571" L). The 13FR070E is ROHS3 compliant while the 13FR070 is not. Packaging configuration also differs: standard versus bulk.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both the 13FR070 and 13FR070E have identical axial package dimensions of 0.205" Dia × 0.571" L (5.20mm × 14.50mm), ensuring compatibility in PCB layouts and through-hole applications.

Q: What applications are these resistors designed for?

A: These are current sense resistors with non-inductive metal element construction. They are designed for precision current measurement and monitoring applications requiring low resistance values with tight tolerance (±1%) and stable performance across the -55°C to 275°C operating range.

Q: Does packaging configuration affect performance?

A: No. The difference between standard and bulk packaging is a procurement and logistics consideration only. Electrical and mechanical performance remains identical regardless of packaging configuration.
