Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S14F5230U is determined by strict equivalence across the following parameters: resistance value (523 Ohms), tolerance (±1%), power rating (0.5W), package type (1210), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), AEC-Q200 automotive rating, and compliance certifications (ROHS3, MSL 1). All identified substitute parts meet these criteria and are qualified for direct replacement in automotive and industrial applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts—ERJ-S14F5230U, AC1210FR-07523RL, and RMCF1210FT523R—are functionally equivalent for direct substitution. Selection between manufacturers should be based on availability, lead time, and supply chain requirements. The ERJ-S14F5230U features anti-sulfur coating; the AC1210FR-07523RL includes moisture-resistant properties. Both RMCF1210FT523R and ERJ-S14F5230U share identical physical dimensions (0.126" L x 0.098" W, 3.20mm x 2.50mm) and maximum seated height (0.028", 0.70mm). The AC1210FR-07523RL has slightly reduced dimensions (0.122" L x 0.102" W, 3.10mm x 2.60mm) and lower seated height (0.024", 0.60mm), which may be relevant for space-constrained PCB layouts. All parts maintain AEC-Q200 automotive qualification and ROHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can AC1210FR-07523RL be used in place of ERJ-S14F5230U? A: Yes. Both parts meet identical electrical specifications (523 Ohms ±1%, 0.5W, ±100ppm/°C, -55°C to 155°C) and automotive AEC-Q200 rating. Physical dimensions differ slightly; verify PCB layout constraints before substitution.

Q: What is the difference between anti-sulfur and moisture-resistant coatings? A: Anti-sulfur coating protects against sulfur-containing environmental contaminants. Moisture-resistant coating reduces moisture absorption. Both are protective measures; selection depends on application environment.

Q: Are all three parts suitable for automotive applications? A: Yes. All three parts carry AEC-Q200 automotive qualification and ROHS3 compliance, meeting automotive industry standards.

Q: Does package size affect substitution? A: All parts use 1210 (3225 Metric) package. AC1210FR-07523RL has slightly smaller physical dimensions; verify PCB footprint compatibility for space-critical designs.

Q: What does MSL 1 (Unlimited) mean? A: MSL 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling.
