Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S14F2941U is determined by strict equivalence across the following parameters:

• Resistance value: 2.94 kOhms
• Tolerance: ±1%
• Power rating: 0.5W
• Package format: 1210 (3225 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Automotive qualification: AEC-Q200
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

The ERJ-14NF2941U meets all electrical and mechanical substitution criteria. This part maintains identical resistance, tolerance, power rating, package dimensions, and thermal characteristics. Both components are AEC-Q200 qualified and ROHS3 compliant, ensuring compatibility in automotive and industrial applications requiring these certifications.

Parameter Comparison

Engineering Selection Recommendations

The ERJ-S14F2941U is the preferred selection for new designs due to its active production status. This part carries full manufacturer support and is recommended for applications requiring long-term availability and supply chain stability.

The ERJ-14NF2941U is electrically and mechanically equivalent and maintains all required certifications including AEC-Q200 automotive qualification and ROHS3 compliance. However, this part is designated as "Not For New Designs," indicating that Panasonic has transitioned this product line. Selection of ERJ-14NF2941U is appropriate only for legacy system maintenance, design revisions of existing products, or situations where supply of the primary part is unavailable.

Both parts are suitable for automotive and industrial applications requiring AEC-Q200 qualification. The identical package footprint, thermal characteristics, and electrical specifications ensure direct substitution without circuit redesign or PCB layout modification.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF2941U be used as a direct replacement for ERJ-S14F2941U in new designs?

A: ERJ-14NF2941U meets all electrical and mechanical specifications for direct substitution. However, it is designated "Not For New Designs" by the manufacturer. New designs should specify ERJ-S14F2941U to ensure long-term availability and manufacturer support.

Q: Are there any differences in the anti-sulfur coating between these parts?

A: The ERJ-S14F2941U includes anti-sulfur coating as a specified feature. The ERJ-14NF2941U does not list anti-sulfur coating in its detailed description. This difference should be evaluated based on application environment and corrosive gas exposure requirements.

Q: Will ERJ-14NF2941U fit the same PCB footprint as ERJ-S14F2941U?

A: Yes. Both parts use the 1210 (3225 Metric) package with identical dimensions: 0.126" L x 0.098" W (3.20mm x 2.50mm) and maximum seated height of 0.028" (0.70mm). No PCB layout modification is required.

Q: Are both parts suitable for automotive applications?

A: Yes. Both ERJ-S14F2941U and ERJ-14NF2941U 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 product status difference?

A: "Active" status indicates the ERJ-S14F2941U is in current production with ongoing manufacturer support. "Not For New Designs" indicates ERJ-14NF2941U is in end-of-life phase. Existing inventory may be available, but future availability is not guaranteed.
