ERJ-S14F1073U Equivalent & Substitute Parts

Part Overview

The ERJ-S14F1073U is a 107 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 822 units in stock.

Substitute parts become necessary when the primary component reaches end-of-life, experiences supply constraints, or when design flexibility is required for multi-source procurement strategies. The ERJ-14NF1073U represents a functionally equivalent alternative from the same manufacturer, though with different product lifecycle status.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S14F1073U is determined by strict equivalence across the following critical parameters:

• Resistance value: 107 kOhms
• Tolerance: ±1%
• Power rating: 0.5W
• 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-14NF1073U meets all these criteria and qualifies as a direct electrical and mechanical substitute. Both parts share identical electrical specifications, physical dimensions, and environmental ratings. The primary distinction lies in product lifecycle status and manufacturing series designation.

Parameter Comparison

Engineering Selection Recommendations

The ERJ-S14F1073U is the preferred selection for new designs due to its active product status and anti-sulfur coating feature. This component maintains full manufacturing support and is recommended for applications requiring long-term supply continuity.

The ERJ-14NF1073U is classified as "Not For New Designs" and should be used only in legacy system maintenance, field replacements, or when existing inventory must be consumed. Despite this lifecycle designation, the part maintains full electrical and mechanical equivalence with identical AEC-Q200 automotive qualification and ROHS3 compliance.

Both parts are suitable for automotive and industrial applications operating within the -55°C to 155°C temperature range. Selection between these parts should be based on design phase (new vs. legacy) and supply chain requirements rather than electrical performance considerations.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF1073U be used as a direct replacement for ERJ-S14F1073U in new designs?

A: Electrically and mechanically, yes. However, the ERJ-14NF1073U carries a "Not For New Designs" status. New designs should specify the ERJ-S14F1073U to ensure long-term manufacturing support and supply availability.

Q: What is the difference between the ERJ-S14 and ERJ-14N series?

A: Both series share identical electrical specifications, package dimensions, and automotive qualifications. The primary difference is product lifecycle status and manufacturing series designation. The ERJ-S14 series is actively manufactured, while the ERJ-14N series is in legacy status.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts measure 0.126" L x 0.098" W (3.20mm x 2.50mm) with a maximum seated height of 0.028" (0.70mm). They are mechanically interchangeable in PCB layouts.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both the ERJ-S14F1073U and ERJ-14NF1073U carry AEC-Q200 automotive qualification and are ROHS3 compliant, suitable for automotive and industrial applications.

Q: What is the significance of the anti-sulfur coating on the ERJ-S14F1073U?

A: The anti-sulfur feature on the ERJ-S14F1073U provides enhanced protection against sulfur-containing environmental contaminants. The ERJ-14NF1073U does not specify this feature, though both parts maintain equivalent electrical performance under standard operating conditions.

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

A: Yes, for field replacements and legacy system maintenance. The identical package, resistance value, tolerance, power rating, and temperature specifications ensure mechanical and electrical compatibility.
