Key Parameters

Substitute Part Grouping Explanation

Substitution of the 14FPR080E is based on the following critical parameters that must remain constant or be exceeded:

• Resistance value: 80 mOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Composition: Metal Element (exact match required)
• Features: Current Sense, Non-Inductive (exact match required)
• Temperature Coefficient: ±50ppm/°C (exact match required)
• Operating Temperature Range: -55°C ~ 200°C (exact match required)
• Package Type: Axial (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)

The power rating may be increased without affecting circuit compatibility, provided the physical dimensions remain within acceptable mounting constraints. The 17FPR080E meets all mandatory electrical and mechanical parameters while offering an increased power rating of 7W, making it a valid substitute for the obsolete 14FPR080E.

Parameter Comparison

Engineering Selection Recommendations

The 17FPR080E is the manufacturer-recommended substitute for the obsolete 14FPR080E. Both parts are manufactured by Ohmite and maintain identical electrical specifications across resistance, tolerance, temperature coefficient, and operating temperature range. The 17FPR080E provides increased power dissipation capability (7W versus 4.5W) while preserving all functional characteristics required for current sense applications.

Both parts maintain ROHS3 compliance and are classified under ECCN EAR99 with identical HTSUS codes (8533.21.0090), ensuring regulatory and compliance continuity. The 17FPR080E is currently in Active product status, providing long-term availability and supply chain stability compared to the Obsolete 14FPR080E.

Physical dimension differences must be evaluated against PCB layout constraints. The 17FPR080E exhibits larger diameter (0.375" versus 0.335") and length (1.500" versus 1.059"), requiring confirmation of mounting space availability in existing designs.

Frequently Asked Questions (FAQ)

Q: Can the 17FPR080E directly replace the 14FPR080E in existing designs?

A: The 17FPR080E is electrically and functionally equivalent to the 14FPR080E across all critical parameters. However, physical dimensions differ; the 17FPR080E is larger in both diameter and length. PCB layout and mounting space must be evaluated before implementation.

Q: Why is the power rating different between these parts?

A: The 17FPR080E provides increased power dissipation capability (7W) while maintaining identical resistance, tolerance, and temperature characteristics. This higher rating does not affect circuit operation and provides additional thermal margin in current sense applications.

Q: Are there any compliance or regulatory differences?

A: Both parts maintain ROHS3 compliance and identical regulatory classifications (ECCN EAR99, HTSUS 8533.21.0090). No compliance differences exist between the two parts.

Q: What is the primary reason for substitution?

A: The 14FPR080E is classified as Obsolete. The 17FPR080E is the manufacturer-recommended active substitute, ensuring continued availability and supply chain support.

Q: Are the temperature operating ranges identical?

A: Yes, both parts operate across -55°C to 200°C with identical temperature coefficients of ±50ppm/°C.
