ERJ-S14F5761U Equivalent & Substitute Parts

Part Overview

The ERJ-S14F5761U is a 5.76 kOhms ±1% thick film chip resistor manufactured by Panasonic Electronic Components in the 1210 (3225 Metric) package format. This component is rated for 0.5W power dissipation and meets AEC-Q200 automotive qualification standards with anti-sulfur protection. The part is currently in active production status with 970 units available in stock.

Substitute parts become necessary when the primary part reaches end-of-life status, inventory constraints occur, or design revisions require components with equivalent electrical and mechanical characteristics. The ERJ-14NF5761U represents a direct functional equivalent from the same manufacturer, though it carries a "Not For New Designs" status designation.

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S14F5761U is determined by strict equivalence across the following parameters:

• Resistance value: 5.76 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.5W minimum
• Package format: 1210 (3225 Metric) physical dimensions
• Composition: Thick film construction
• Temperature coefficient: ±100ppm/°C or better
• Operating temperature range: -55°C to 155°C minimum
• Automotive qualification: AEC-Q200 certification
• Termination count: 2 terminations (standard for chip resistors)

The ERJ-14NF5761U qualifies as a direct substitute based on identical electrical specifications and package compatibility. Both parts share the same resistance, tolerance, power rating, package dimensions, and automotive qualification level. The primary distinction is product lifecycle status, where the ERJ-S14F5761U is designated for active new designs while the ERJ-14NF5761U is restricted from new design implementation.

Parameter Comparison

Engineering Selection Recommendations

For new design implementations, the ERJ-S14F5761U is the specified component choice due to its active product status and ongoing manufacturer support. This part carries full AEC-Q200 automotive qualification and ROHS3 compliance, making it suitable for automotive and industrial applications requiring long-term supply chain stability.

The ERJ-14NF5761U serves as a functional equivalent for legacy system maintenance, field repairs, or applications where existing inventory must be utilized. However, its "Not For New Designs" designation indicates that Panasonic has transitioned this part to end-of-life status. Use of this substitute in new designs is not recommended due to potential future supply discontinuation.

Both parts meet identical electrical and mechanical specifications, ensuring direct pin-for-pin and footprint compatibility on PCB assemblies. Selection between these parts should be driven by design phase (new versus legacy) and supply chain requirements rather than technical performance differences.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF5761U be used as a direct replacement for ERJ-S14F5761U in new designs?

A: Electrically and mechanically, yes. However, the ERJ-14NF5761U carries a "Not For New Designs" status, indicating manufacturer end-of-life planning. New designs should specify the ERJ-S14F5761U to ensure long-term supply availability and manufacturer support.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts use the 1210 (3225 Metric) package with identical length (0.126" / 3.20mm), width (0.098" / 2.50mm), and maximum seated height (0.028" / 0.70mm). PCB footprints are interchangeable.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both the ERJ-S14F5761U and ERJ-14NF5761U carry AEC-Q200 automotive qualification and are ROHS3 compliant, meeting automotive industry standards for reliability and environmental compliance.

Q: What is the significance of the temperature coefficient specification?

A: Both parts specify ±100ppm/°C temperature coefficient, meaning resistance value changes by a maximum of 100 parts per million for each degree Celsius change in operating temperature. This specification is identical across both parts and ensures predictable performance across the -55°C to 155°C operating range.

Q: Can these parts be used interchangeably in existing assemblies?

A: Yes, for maintenance and repair of existing systems. The identical electrical characteristics (5.76 kOhms ±1%, 0.5W), package format, and automotive ratings ensure functional equivalence. However, new production designs should continue using the ERJ-S14F5761U due to its active status.
