Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Ohmite 13FPR040E are identified based on strict parametric equivalence. The critical parameters that determine substitutability are:

• Resistance value: 40 mOhms
• Tolerance: ±1%
• Power rating: 3W
• Composition: Metal Element
• Features: Current Sense, Non-Inductive
• Temperature coefficient: ±50ppm/°C
• Operating temperature range: -55°C ~ 200°C
• Package type: Axial
• Number of terminations: 4

Parts meeting all these criteria are considered parametric equivalents and may be substituted in applications where the original part is specified.

Parameter Comparison

Engineering Selection Recommendations

Both the main part (13FPR040E) and its substitute maintain Active product status and meet RoHS compliance requirements. The substitute part achieves ROHS3 Compliant status, which represents an enhanced environmental compliance certification. All electrical parameters, including resistance, tolerance, power rating, temperature coefficient, and operating temperature range, are identical between the two parts. Physical dimensions show minor variations within the axial package specification. Selection between these parts may be based on inventory availability, compliance certification requirements, or specific PCB layout constraints related to the dimensional differences.

Frequently Asked Questions (FAQ)

Q: Can the substitute 13FPR040E be used in place of the main 13FPR040E?

A: Yes. Both parts are parametrically equivalent with identical electrical specifications: 40 mOhms resistance, ±1% tolerance, 3W power rating, ±50ppm/°C temperature coefficient, and -55°C ~ 200°C operating range. Both feature metal element composition with current sense and non-inductive characteristics.

Q: Are there physical dimension differences between the main and substitute parts?

A: Yes. The main part measures 0.205" Dia x 0.571" L (5.20mm x 14.50mm), while the substitute measures 0.200" Dia x 0.626" L (5.08mm x 15.90mm). Both are axial package types with 4 terminations. Verify PCB layout compatibility before substitution.

Q: What is the difference between RoHS Compliant and ROHS3 Compliant?

A: ROHS3 Compliant represents an updated compliance certification standard. Both certifications indicate environmental compliance; ROHS3 reflects a more recent regulatory framework. Both parts meet environmental requirements for electronic component use.

Q: Are both parts suitable for current sensing applications?

A: Yes. Both the main and substitute parts are specified with current sense and non-inductive features, making them suitable for precision current sensing circuits requiring low resistance values and stable temperature performance.

Q: What inventory levels are available?

A: The main part has 1096 Pcs in stock, while the substitute has 1686 Pcs in stock. Availability may influence selection based on project timeline requirements.
