ERJ-S14F57R6U Equivalent & Substitute Parts

Part Overview

The ERJ-S14F57R6U is a 57.6 Ohm ±1% thick film chip resistor rated at 0.5W (1/2W) in a 1210 (3225 Metric) package. Manufactured by Panasonic Electronic Components, this component features anti-sulfur coating and automotive AEC-Q200 qualification, making it suitable for harsh automotive environments. The part is currently in active production status with 882 units in stock.

Substitute parts become necessary when the primary part reaches end-of-life status, inventory constraints occur, or design revisions require components from alternative product lines that maintain equivalent electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S14F57R6U is determined by strict equivalence across the following critical parameters:

• Resistance value: 57.6 Ohms
• Tolerance: ±1%
• Power rating: 0.5W (1/2W)
• Package: 1210 (3225 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Automotive qualification: AEC-Q200
• Moisture sensitivity: MSL 1
• RoHS compliance: ROHS3

The ERJ-14NF57R6U meets all substitution criteria. While it carries a "Not For New Designs" status, it maintains identical electrical specifications, package dimensions, and automotive certifications. The primary distinction is the absence of anti-sulfur coating in the ERJ-14NF57R6U variant, which may be relevant for specific corrosive environments but does not affect core electrical performance or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The ERJ-S14F57R6U is the preferred selection for new designs due to its active production status and anti-sulfur coating feature, which provides enhanced reliability in sulfur-rich environments common in automotive applications.

The ERJ-14NF57R6U is a valid substitute for existing designs or applications where inventory of the primary part is unavailable. Its "Not For New Designs" status reflects Panasonic's product lifecycle management rather than technical inadequacy. All electrical and mechanical parameters remain equivalent, and AEC-Q200 automotive qualification is maintained. The absence of anti-sulfur coating should be evaluated against specific application requirements; in standard automotive environments without elevated sulfur exposure, this difference is not functionally significant.

Both parts are ROHS3 compliant and carry MSL 1 rating, indicating no moisture sensitivity constraints during storage or handling.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF57R6U be used as a direct replacement for ERJ-S14F57R6U in automotive applications?

A: Yes. Both parts meet AEC-Q200 automotive qualification and share identical electrical specifications (57.6 Ohms ±1%, 0.5W, ±100ppm/°C). The primary difference is the anti-sulfur coating present in the ERJ-S14F57R6U. For applications without specific sulfur exposure requirements, the ERJ-14NF57R6U provides equivalent performance.

Q: Are there any PCB layout or assembly differences between these parts?

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 interchangeable.

Q: What does "Not For New Designs" mean for the ERJ-14NF57R6U?

A: This designation indicates that Panasonic recommends using the ERJ-S14F57R6U for new product development. However, the ERJ-14NF57R6U remains a valid substitute for existing designs or when primary part availability is constrained. The part continues to meet all published specifications and certifications.

Q: Are moisture sensitivity levels the same for both parts?

A: Yes. Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity constraints. Standard storage and handling practices apply without special desiccant or baking requirements.

Q: Do both parts comply with RoHS regulations?

A: Yes. Both ERJ-S14F57R6U and ERJ-14NF57R6U are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for automotive and industrial applications.
