Equivalent & Substitute Parts for ERJ-S14F1150U

Part Overview

The ERJ-S14F1150U is a 115 Ohms ±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 855 units available in stock.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the same package footprint and performance specifications. Alternative sources may be required due to supply chain considerations, design phase transitions, or specific manufacturing certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ERJ-S14F1150U are qualified based on the following criteria:

Electrical Parameters: Resistance value (115 Ohms), tolerance (±1%), power rating (0.5W), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C) must be identical.

Mechanical Parameters: Package type (1210 / 3225 Metric), number of terminations (2), and physical dimensions must match or be compatible with the original footprint.

Compliance & Certifications: AEC-Q200 automotive qualification, ROHS3 compliance, and MSL rating (1) are maintained across all qualified substitutes.

Composition: Thick film construction is consistent across all substitute options.

The identified substitute parts meet all these criteria and are therefore electrically and mechanically interchangeable with the ERJ-S14F1150U in applications requiring these specifications.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: ERJ-S14F1150U remains the recommended choice for new designs. This part is in active production status with anti-sulfur coating and maintains full AEC-Q200 automotive qualification. Current inventory of 855 units supports immediate availability.

First Alternative: CRCW1210115RFKEA (Vishay Dale) is an active production substitute with identical electrical specifications and AEC-Q200 compliance. This part offers 8,132 units in stock and is suitable for new designs. The seated height is 0.024" (0.60mm) compared to 0.028" (0.70mm) for the primary part; this difference is within standard PCB assembly tolerances for 1210 packages.

Legacy Alternative: ERJ-14NF1150U (Panasonic) maintains full electrical and mechanical compatibility but carries a "Not For New Designs" status. This part should be used only for replacement or repair of existing assemblies where design continuity is required. Inventory of 16,086 units is available.

All three parts are ROHS3 compliant, MSL 1 rated, and suitable for automotive applications requiring AEC-Q200 qualification.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF1150U replace ERJ-S14F1150U in new designs?

A: ERJ-14NF1150U is electrically and mechanically compatible but is marked "Not For New Designs." For new product development, use ERJ-S14F1150U or CRCW1210115RFKEA instead.

Q: What is the difference between the anti-sulfur coating on ERJ-S14F1150U and standard ERJ-14NF1150U?

A: The anti-sulfur feature is specified only for ERJ-S14F1150U. Both parts meet AEC-Q200 requirements, but the anti-sulfur coating provides additional protection in high-sulfur environments. This distinction is based on provided specifications only.

Q: Are there height differences between these parts that affect PCB assembly?

A: CRCW1210115RFKEA has a maximum seated height of 0.024" (0.60mm), while ERJ-S14F1150U and ERJ-14NF1150U are 0.028" (0.70mm). Both heights are within standard 1210 package specifications and compatible with typical PCB assembly processes.

Q: Do all three parts have the same moisture sensitivity rating?

A: Yes. All three parts are MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Which substitute should be selected for automotive applications?

A: All three parts carry AEC-Q200 automotive qualification and ROHS3 compliance. For new automotive designs, ERJ-S14F1150U or CRCW1210115RFKEA are appropriate. ERJ-14NF1150U is suitable only for replacement applications.
