Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Ohmite 13FR025 is determined by the following parameters:

• Resistance value: 25 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 x 0.571" L (5.20mm x 14.50mm)
• Number of terminations: 2

The identified substitute part maintains all electrical and mechanical parameters. Variations in packaging format (tape and reel versus bulk) and RoHS compliance status do not affect functional interchangeability in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the 13FR025 and 13FR025E are Active status products from Ohmite with identical electrical and mechanical specifications. Selection between these parts should be based on the following criteria:

The 13FR025E offers ROHS3 compliance, making it suitable for applications subject to RoHS regulations. The 13FR025 is RoHS non-compliant and should be selected only when RoHS compliance is not a requirement.

Packaging format differs between the two parts. The 13FR025 is supplied in standard packaging, while the 13FR025E is supplied in bulk format. Bulk packaging may be preferred for high-volume manufacturing operations. The 13FR025E maintains significantly higher inventory availability at 7883 pieces compared to 791 pieces for the 13FR025.

Both parts are suitable for current sense applications requiring non-inductive metal element resistors with 25 mOhms resistance and 3W power dissipation capability across the -55°C to 275°C operating range.

Frequently Asked Questions (FAQ)

Q: Are the 13FR025 and 13FR025E electrically identical?

A: Yes. Both parts have identical resistance (25 mOhms), tolerance (±1%), power rating (3W), temperature coefficient (±50ppm/°C), and operating temperature range (-55°C to 275°C).

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 13FR025E is ROHS3 compliant, while the 13FR025 is RoHS non-compliant. Inventory levels also differ, with the 13FR025E having higher stock availability.

Q: Can I use the 13FR025E as a direct replacement for the 13FR025?

A: Yes, the 13FR025E is a direct functional substitute. Physical dimensions, termination count, and all electrical parameters are identical. Selection should be based on RoHS compliance requirements and packaging format needs.

Q: Are there any mechanical compatibility issues between these parts?

A: No. Both parts use identical axial packaging with 0.205" diameter and 0.571" length (5.20mm x 14.50mm). They are mechanically interchangeable on PCBs designed for axial through-hole resistors.

Q: Which part should I specify for new designs?

A: For new designs, the 13FR025E is recommended due to ROHS3 compliance and higher inventory availability, unless specific design constraints require the 13FR025.
