ERJ-S14F6193U Equivalent & Substitute Parts

Part Overview

The ERJ-S14F6193U is a 619 kOhms ±1% 0.5W thick film chip resistor in 1210 (3225 Metric) package manufactured by Panasonic Electronic Components. This component features anti-sulfur coating and automotive AEC-Q200 qualification, designed for high-reliability applications in automotive and industrial environments. The part is currently in active production status with RoHS3 compliance and unlimited moisture sensitivity level (MSL 1).

Substitute parts become necessary when the primary component experiences supply constraints, inventory limitations, or when design requirements permit selection from qualified alternatives that maintain electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S14F6193U is determined by strict equivalence across the following parameters:

• Resistance value: 619 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.5W / 1/2W (exact match required)
• Package: 1210 (3225 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)
• Automotive qualification: AEC-Q200 (exact match required)

The ERJ-14NF6193U qualifies as a direct substitute based on complete alignment with all electrical and mechanical parameters listed above. Differences in product status, RoHS compliance, and anti-sulfur coating do not affect functional substitutability when electrical and thermal performance requirements are met.

Parameter Comparison

Engineering Selection Recommendations

The ERJ-S14F6193U is the preferred selection for new designs due to its active product status and RoHS3 compliance. This part meets current regulatory requirements and benefits from ongoing manufacturer support and supply continuity.

The ERJ-14NF6193U is electrically and mechanically equivalent and may be used as a substitute in existing designs or legacy applications where RoHS3 compliance is not mandated. However, this part carries a "Not For New Designs" status, indicating that Panasonic has transitioned this product line. Selection of ERJ-14NF6193U should be limited to applications where supply of the primary part is unavailable and design freeze conditions permit substitution.

The absence of anti-sulfur coating on ERJ-14NF6193U may be a consideration in high-sulfur environments; however, this difference does not affect electrical performance in standard operating conditions.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF6193U be used as a direct replacement for ERJ-S14F6193U?

A: Yes. Both parts share identical electrical specifications (619 kOhms ±1%, 0.5W), thermal characteristics (±100ppm/°C, -55°C ~ 155°C), package dimensions (1210), and automotive qualification (AEC-Q200). Physical and functional interchangeability is confirmed.

Q: What is the difference between these two parts?

A: The primary differences are product lifecycle status, RoHS compliance, and anti-sulfur coating. ERJ-S14F6193U is actively produced with RoHS3 compliance and anti-sulfur protection. ERJ-14NF6193U is marked "Not For New Designs," is RoHS non-compliant, and lacks anti-sulfur coating. Electrical and mechanical performance are identical.

Q: Should I use ERJ-14NF6193U in a new design?

A: No. For new designs, ERJ-S14F6193U is the appropriate selection due to active production status and RoHS3 compliance. ERJ-14NF6193U should be reserved for legacy applications or situations where ERJ-S14F6193U supply is constrained.

Q: Are there any package compatibility concerns?

A: No. 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 (0.028" / 0.70mm). PCB footprints and assembly processes are fully compatible.

Q: What is the moisture sensitivity level for these parts?

A: Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard handling and storage procedures apply without special desiccant or baking requirements.
