Key Parameters

Substitute Part Grouping Explanation

Substitution of the 14FPR015E is determined by the following critical parameters:

• Resistance value: 15 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 to 200°C (exact match required)
• Package Type: Axial (exact match required)

The 17FPR015E meets all substitution criteria. The primary difference is an increased power rating of 7W compared to the original 4.5W, which represents an enhancement in thermal capability while maintaining all electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The 17FPR015E is the direct substitute for the obsolete 14FPR015E. Both components are manufactured by Ohmite and maintain identical electrical specifications including resistance value, tolerance, temperature coefficient, and operating temperature range. The 17FPR015E carries active product status, ensuring long-term availability and supply chain continuity.

The increased power rating of 7W in the 17FPR015E provides enhanced thermal performance compared to the 4.5W rating of the original part. Both components maintain ROHS3 compliance and are suitable for current sense applications requiring non-inductive metal element construction.

Physical dimensions differ between the two parts due to the increased power rating. The 17FPR015E measures 0.375" diameter by 1.500" length compared to the 14FPR015E at 0.335" diameter by 1.059" length. PCB layout and mechanical clearance must be evaluated during design transition.

Frequently Asked Questions (FAQ)

Q: Can the 17FPR015E directly replace the 14FPR015E in existing designs?

A: The 17FPR015E is electrically equivalent to the 14FPR015E across all specified parameters. Physical dimensions are larger due to increased power rating, requiring verification of PCB layout and mechanical clearance.

Q: What is the primary reason for substitution?

A: The 14FPR015E is classified as obsolete. The 17FPR015E is the manufacturer-recommended active substitute, ensuring continued component availability.

Q: Are there any compliance differences between these parts?

A: Both components maintain ROHS3 compliance. No compliance differences exist between the 14FPR015E and 17FPR015E.

Q: How do the power ratings affect circuit performance?

A: The 17FPR015E's 7W rating provides greater thermal headroom than the 14FPR015E's 4.5W rating. Electrical performance remains identical at equivalent power dissipation levels within the original 4.5W specification.

Q: Are dimensional changes critical for PCB redesign?

A: Dimensional differences must be evaluated during design transition. The 17FPR015E is larger in both diameter and length, requiring confirmation that PCB layout accommodates the increased size.
