Substitute Part Grouping Explanation

Substitute parts for the 13FR150 are identified based on strict electrical and mechanical parameter matching. The primary substitution criterion is the 13FR150E, which maintains identical specifications across all critical parameters: 150 mOhms resistance value, ±1% tolerance, 3W power rating, metal element composition, axial package configuration, ±50ppm/°C temperature coefficient, and -55°C to 275°C operating temperature range. Physical dimensions remain constant at 0.205" Dia x 0.571" L (5.20mm x 14.50mm). The key differentiator between the main part and substitute is packaging format and RoHS compliance status, which do not affect electrical or mechanical interchangeability in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the 13FR150 and 13FR150E are Active status components manufactured by Ohmite with identical electrical and mechanical specifications. Selection between these parts should be based on regulatory compliance requirements and supply chain considerations. The 13FR150E offers ROHS3 compliance, making it suitable for applications subject to RoHS3 regulations. The 13FR150 maintains RoHS non-compliant status. Both components are REACH Unaffected. Inventory availability differs significantly, with the 13FR150E offering substantially higher stock levels (12,154 units versus 1,068 units). For applications without specific RoHS compliance mandates, either part provides equivalent performance. For regulated environments requiring RoHS3 compliance, the 13FR150E is the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Are the 13FR150 and 13FR150E electrically interchangeable? A: Yes. Both parts share identical resistance value (150 mOhms), tolerance (±1%), power rating (3W), temperature coefficient (±50ppm/°C), and operating temperature range (-55°C to 275°C). Electrical performance is equivalent.

Q: What is the difference between these two part numbers? A: The primary differences are packaging format (standard versus bulk) and RoHS compliance status. The 13FR150E is ROHS3 compliant, while the 13FR150 is RoHS non-compliant. All electrical and mechanical specifications remain identical.

Q: Can I use the 13FR150E as a direct replacement for the 13FR150 in my circuit? A: Yes, the 13FR150E is a direct mechanical and electrical substitute. Physical dimensions, termination configuration, and all performance parameters are identical. Substitution is valid for any application using the 13FR150.

Q: Does the packaging format difference affect circuit performance? A: No. The packaging format difference (standard versus bulk) refers only to how components are supplied and does not affect electrical or mechanical performance in circuit applications.

Q: Which part should I select for new designs? A: For new designs subject to RoHS3 regulations, select the 13FR150E. For applications without RoHS compliance requirements, either part is suitable. The 13FR150E also offers superior inventory availability.

Q: Are both parts suitable for current sense applications? A: Yes. Both the 13FR150 and 13FR150E are designed with current sense and non-inductive features, making them suitable for precision current measurement applications across their full operating temperature range.
