ERJ-S14F1180U Equivalent & Substitute Parts

Part Overview

The ERJ-S14F1180U is a 118 Ohms ±1% thick film chip resistor manufactured by Panasonic Electronic Components in the 1210 (3225 Metric) package format. This component is rated for 0.5W power dissipation and is designed for automotive applications with AEC-Q200 qualification and anti-sulfur protection. The part is currently in active production status with 1009 units available in stock.

Identifying equivalent and substitute parts is necessary when the primary part becomes unavailable, when design requirements shift toward alternative manufacturing sources, or when transitioning from legacy components to current production lines.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S14F1180U is determined by strict equivalence across the following parameters:

• Resistance value: 118 Ohms
• Tolerance: ±1%
• Power rating: 0.5W minimum
• Package format: 1210 (3225 Metric)
• Composition: Thick film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C minimum
• Automotive qualification: AEC-Q200
• RoHS compliance: ROHS3 or equivalent

The ERJ-14NF1180U from Panasonic Electronic Components meets all electrical and mechanical parameters required for direct substitution. This part maintains identical resistance, tolerance, power rating, package dimensions, and thermal characteristics. Both components are AEC-Q200 qualified and ROHS3 compliant.

Parameter Comparison

Engineering Selection Recommendations

The ERJ-S14F1180U is the preferred selection for new designs due to its active production status. This part carries the anti-sulfur feature and maintains full AEC-Q200 automotive qualification with ROHS3 compliance.

The ERJ-14NF1180U is electrically and mechanically equivalent and may be used as a substitute when the primary part is unavailable. However, this part is designated as "Not For New Designs" by the manufacturer. Selection of this substitute should be limited to legacy system support, field replacements, or situations where supply constraints necessitate its use. Both parts are manufactured by Panasonic Electronic Components and share identical electrical performance characteristics, package dimensions, and environmental ratings.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF1180U be used as a direct replacement for ERJ-S14F1180U in automotive applications?

A: Yes. Both parts are AEC-Q200 qualified, share identical electrical specifications (118 Ohms ±1%, 0.5W), operate across the same temperature range (-55°C to 155°C), and use the same 1210 package format with identical physical dimensions. The primary difference is product status; ERJ-14NF1180U is not recommended for new designs.

Q: What is the significance of the "Not For New Designs" status on the ERJ-14NF1180U?

A: This designation indicates the manufacturer is transitioning this part to end-of-life status. While the part remains functionally equivalent and available in inventory, Panasonic recommends using the ERJ-S14F1180U for new product development to ensure long-term supply continuity.

Q: Are the physical dimensions identical between these two 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 fully compatible for PCB layout and assembly processes.

Q: Do both parts meet the same compliance and certification requirements?

A: Yes. Both ERJ-S14F1180U and ERJ-14NF1180U are ROHS3 compliant, AEC-Q200 qualified, and carry MSL 1 (Unlimited) moisture sensitivity ratings. They meet identical environmental and regulatory standards.

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

A: These represent different product series within Panasonic's resistor portfolio. The ERJ-S14 series (represented by ERJ-S14F1180U) is the current active production line. The ERJ-14N series (represented by ERJ-14NF1180U) is a legacy series transitioning to end-of-life status. Both series use identical thick film technology and meet the same electrical and mechanical specifications for this 118 Ohm value.
