Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S14F1072U is determined by strict equivalence across the following parameters: resistance value (10.7 kOhms), tolerance (±1%), power rating (0.5W), package format (1210), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and AEC-Q200 automotive qualification.

The ERJ-14NF1072U qualifies as a direct substitute based on matching all electrical specifications and package requirements. This part maintains identical resistance, tolerance, power rating, temperature characteristics, and automotive certification. The primary distinction is product status: ERJ-14NF1072U is designated "Not For New Designs," indicating it remains available for existing applications but is not recommended for new circuit development.

Parameter Comparison

Engineering Selection Recommendations

For new circuit designs, the ERJ-S14F1072U is the preferred selection due to its active production status and ongoing manufacturer support. This part provides assurance of long-term availability and compliance with current manufacturing standards.

The ERJ-14NF1072U serves as a viable substitute for existing applications or legacy designs where component replacement is required. Its "Not For New Designs" status indicates that while the part meets all electrical and mechanical requirements, Panasonic has transitioned this series to mature product status. Selection of this substitute is appropriate only when the primary part is unavailable and the application permits use of a legacy-qualified component.

Both parts carry identical AEC-Q200 automotive certification, ROHS3 compliance, and unlimited moisture sensitivity rating, ensuring compatibility within automotive and industrial applications requiring these qualifications.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF1072U be used as a direct replacement for ERJ-S14F1072U in new designs?

A: Electrically and mechanically, yes. However, ERJ-14NF1072U carries "Not For New Designs" status. New designs should specify ERJ-S14F1072U to ensure long-term availability and manufacturer support.

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

A: The ERJ-S14F1072U explicitly includes anti-sulfur coating in its specification. The ERJ-14NF1072U specification does not list this feature. This distinction may be relevant for applications in high-sulfur environments.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both ERJ-S14F1072U and ERJ-14NF1072U carry AEC-Q200 automotive qualification and are suitable for automotive applications.

Q: Are the physical dimensions identical?

A: Yes. Both parts use the 1210 (3225 Metric) package with identical dimensions: 0.126" L × 0.098" W (3.20mm × 2.50mm) and maximum seated height of 0.028" (0.70mm).

Q: What is the significance of the product status difference?

A: ERJ-S14F1072U (Active) indicates ongoing production and manufacturer commitment. ERJ-14NF1072U (Not For New Designs) indicates the part is available but no longer recommended for new circuit development, typically due to series maturation or transition to newer product lines.

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

A: Yes, provided the application does not depend on the anti-sulfur coating feature specific to ERJ-S14F1072U. Electrical performance, temperature characteristics, and automotive certification are equivalent.
