Substitute Part Grouping Explanation

Substitution for the Ohmite 12FR010 is based on electrical and mechanical parameter equivalence. The substitute part must maintain identical specifications across the following critical parameters:

• Resistance value: 10 mOhms
• Tolerance: ±1%
• Power rating: 2W
• Composition: Metal Element
• Temperature coefficient: ±100 ppm/°C
• Operating temperature range: -55°C to 275°C
• Package configuration: Axial
• Physical dimensions: 0.094" Dia × 0.417" L
• Functional features: Current sense, non-inductive

The Ohmite 12FR010E meets all these criteria and is classified as a direct substitute. The primary difference between the main part and substitute is packaging format and RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

Both the Ohmite 12FR010 and 12FR010E are electrically and mechanically identical. Selection between these parts should be based on the following criteria:

12FR010 is appropriate for applications where RoHS non-compliance is acceptable or where tape/reel packaging is required for automated assembly processes.

12FR010E is the preferred choice for applications requiring RoHS3 compliance. This part is also available in bulk packaging format, which may be suitable for manual assembly or lower-volume production runs. The 12FR010E offers greater inventory availability (3830 pcs vs. 964 pcs).

Both parts maintain active product status and are manufactured by Ohmite with identical electrical performance characteristics.

Frequently Asked Questions (FAQ)

Q: Are the 12FR010 and 12FR010E electrically interchangeable?

A: Yes. Both parts have identical resistance (10 mOhms), tolerance (±1%), power rating (2W), temperature coefficient (±100 ppm/°C), and operating temperature range (-55°C to 275°C). They are functionally equivalent in all electrical parameters.

Q: What is the difference between these two part numbers?

A: The primary differences are packaging format (tape/reel vs. bulk) and RoHS compliance status. The 12FR010E is RoHS3 compliant, while the 12FR010 is RoHS non-compliant. Electrical and mechanical specifications are identical.

Q: Can I use 12FR010E as a direct replacement for 12FR010 in my design?

A: Yes, the 12FR010E is a direct substitute. Physical dimensions, pin configuration, and all electrical parameters are identical. Verify that your application requirements align with the RoHS3 compliance status of the 12FR010E.

Q: Does packaging format affect performance?

A: No. Tape/reel and bulk packaging formats do not affect component performance. Packaging selection is based on assembly process requirements and inventory management preferences.

Q: Are there any temperature or environmental limitations I should consider?

A: Both parts operate across the same temperature range (-55°C to 275°C) and have identical temperature coefficients (±100 ppm/°C). No additional environmental limitations apply to either part.
