Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S14F1913U is determined by strict equivalence across the following parameters:

• Resistance value: 191 kOhms
• Tolerance: ±1%
• Power rating: 0.5W (1/2W)
• Package: 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-14NF1913U meets all substitution criteria. While this part carries a "Not For New Designs" status, it maintains complete electrical and mechanical compatibility with the ERJ-S14F1913U. The primary distinction is the absence of anti-sulfur coating in the ERJ-14NF1913U; however, both parts share identical core specifications and automotive qualification.

Parameter Comparison

Engineering Selection Recommendations

The ERJ-S14F1913U is the preferred selection for new designs due to its active production status and anti-sulfur coating feature, which provides enhanced reliability in corrosive environments. Both parts maintain identical electrical performance and automotive AEC-Q200 qualification.

The ERJ-14NF1913U serves as a direct substitute for existing designs or applications where inventory of the primary part is unavailable. Its "Not For New Designs" status reflects manufacturing lifecycle management rather than technical deficiency. All electrical and mechanical parameters remain equivalent to the ERJ-S14F1913U, and both parts satisfy ROHS3 compliance and automotive reliability standards.

Selection between these parts should be based on design phase (new vs. existing), inventory availability, and environmental exposure considerations. The anti-sulfur feature of the ERJ-S14F1913U provides additional protection in high-sulfur environments; however, the ERJ-14NF1913U remains suitable for standard automotive and industrial applications.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF1913U be used as a direct replacement for ERJ-S14F1913U in existing assemblies?

A: Yes. Both parts share identical electrical specifications (191 kOhms ±1%, 0.5W), package dimensions (1210 / 3225 Metric), temperature characteristics (±100ppm/°C, -55°C ~ 155°C), and automotive AEC-Q200 qualification. The primary difference is the anti-sulfur coating present in the ERJ-S14F1913U.

Q: What does "Not For New Designs" status mean for the ERJ-14NF1913U?

A: This designation indicates the part is in mature production phase and may be subject to discontinuation. It remains fully functional and compliant with all specifications. New designs should prioritize the ERJ-S14F1913U; however, the ERJ-14NF1913U is suitable for sustaining production and field replacements.

Q: Are there package compatibility concerns between these parts?

A: No. Both parts use identical 1210 (3225 Metric) package with matching footprint dimensions (0.126" L x 0.098" W, 3.20mm x 2.50mm) and height (0.028" / 0.70mm maximum). PCB layout and assembly processes require no modification.

Q: Do both parts meet automotive reliability standards?

A: Yes. Both ERJ-S14F1913U and ERJ-14NF1913U carry AEC-Q200 qualification and are suitable for automotive applications. Both maintain ROHS3 compliance and MSL 1 (unlimited moisture sensitivity level).

Q: What is the significance of anti-sulfur coating in the ERJ-S14F1913U?

A: Anti-sulfur coating provides enhanced protection against sulfur-containing contaminants in high-corrosion environments. For applications with standard environmental exposure, both parts perform equivalently. Selection should consider specific operating environment requirements.
