Substitute Part Grouping Explanation

Substitution eligibility for the 13FR015 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part 13FR015E maintains identical specifications in resistance value (15 mOhms), tolerance (±1%), power rating (3W), composition (metal element), current sense and non-inductive features, temperature coefficient (±50ppm/°C), operating temperature range (-55°C to 275°C), package type (axial), and physical dimensions (0.205" Dia × 0.571" L).

The primary distinction between the main part and its substitute is packaging configuration and compliance status. The 13FR015E is supplied in bulk packaging and carries ROHS3 compliance certification, whereas the 13FR015 is supplied with standard packaging and is RoHS non-compliant. Both parts are manufactured by Ohmite within the same Series 10 product line and share identical functional and mechanical characteristics.

Parameter Comparison

Engineering Selection Recommendations

Selection between 13FR015 and 13FR015E should be based on compliance and supply requirements:

The 13FR015E is the preferred selection for applications requiring ROHS3 compliance certification. This variant maintains all electrical and mechanical specifications of the original 13FR015 while meeting current regulatory requirements for restricted hazardous substances. The 13FR015E also offers higher inventory availability at 1241 units compared to 759 units for the 13FR015.

The 13FR015 remains suitable for applications where RoHS compliance is not a requirement and standard packaging is acceptable. Both parts are Active status products manufactured by Ohmite and are electrically and mechanically interchangeable.

Frequently Asked Questions (FAQ)

Q: Are 13FR015 and 13FR015E electrically identical?

A: Yes. Both parts share identical resistance value (15 mOhms), tolerance (±1%), power rating (3W), temperature coefficient (±50ppm/°C), and operating temperature range (-55°C to 275°C). They are electrically equivalent for all circuit applications.

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

A: The primary differences are packaging configuration (standard versus bulk) and RoHS compliance status (non-compliant versus ROHS3 compliant). All electrical and mechanical specifications remain identical.

Q: Can 13FR015E replace 13FR015 in existing designs?

A: Yes. The 13FR015E is a direct substitute with identical axial package dimensions (0.205" Dia × 0.571" L), termination count (2), and all functional characteristics. No circuit modifications are required.

Q: Which part should be selected for new designs?

A: The 13FR015E is recommended for new designs due to ROHS3 compliance certification and higher inventory availability, provided bulk packaging is acceptable for procurement processes.

Q: Are there any thermal or performance differences between these parts?

A: No. Both parts operate identically across the full temperature range of -55°C to 275°C with the same temperature coefficient of ±50ppm/°C and non-inductive metal element construction.
