Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RCS2012F38R3CS are qualified based on strict electrical and mechanical parameter matching. The substitution criteria are:

Electrical Parameters (Must Match Exactly):

• Resistance value: 38.3 Ohms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters (Must Match Exactly):

• Package / Case: 0805 (2012 Metric)
• Number of terminations: 2
• Composition: Thick Film

Compliance Parameters (Must Match or Exceed):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

All identified substitute parts meet these criteria. Variations in physical dimensions (height, length, width) within standard 0805 tolerances and differences in specific features (anti-sulfur vs. automotive qualification) do not affect functional substitutability for this resistance value and power rating.

Parameter Comparison

Engineering Selection Recommendations

All three parts—RCS2012F38R3CS (Samsung Electro-Mechanics), ERJ-6ENF38R3V (Panasonic Electronic Components), and RC0805FR-0738R3L (YAGEO)—are functionally equivalent for 38.3 Ohm ±1% 0.125W 0805 applications. Selection between these parts should be based on the following factors:

Product Status & Availability: All three parts maintain Active product status. Current inventory levels differ: Samsung RCS2012F38R3CS (1149 units), Panasonic ERJ-6ENF38R3V (48889 units), and YAGEO RC0805FR-0738R3L (9756 units).

Compliance & Certifications: All parts are ROHS3 Compliant, REACH Unaffected, and classified as EAR99. The Panasonic ERJ-6ENF38R3V carries AEC-Q200 automotive qualification, which provides additional reliability assurance for automotive and high-reliability applications. The Samsung RCS2012F38R3CS and YAGEO RC0805FR-0738R3L feature moisture-resistant properties suitable for general industrial applications.

Physical Dimensions: Height variations are within standard 0805 package tolerances (0.024" to 0.028" seated height). These differences do not affect PCB assembly compatibility or electrical performance.

Feature Differentiation: Samsung RCS2012F38R3CS includes anti-sulfur protection. Panasonic ERJ-6ENF38R3V includes automotive AEC-Q200 qualification. YAGEO RC0805FR-0738R3L includes moisture-resistant properties. Feature selection depends on application environment and reliability requirements.

Frequently Asked Questions (FAQ)

Q: Can ERJ-6ENF38R3V replace RCS2012F38R3CS in any application?

A: Yes. Both parts share identical electrical specifications (38.3 Ohms ±1%, 0.125W, ±100ppm/°C, -55°C ~ 155°C) and mechanical compatibility (0805 package, 2 terminations). The Panasonic part includes AEC-Q200 automotive qualification, which does not restrict its use in non-automotive applications.

Q: What is the difference between the three substitute parts?

A: All three parts meet the core electrical and mechanical requirements. The primary differences are: (1) Samsung RCS2012F38R3CS features anti-sulfur protection; (2) Panasonic ERJ-6ENF38R3V includes AEC-Q200 automotive qualification; (3) YAGEO RC0805FR-0738R3L features moisture-resistant properties. Seated height varies slightly (0.024" to 0.028"), which is within standard 0805 tolerances.

Q: Are these parts pin-compatible?

A: Yes. All parts have 2 terminations in 0805 (2012 Metric) package configuration with identical footprint dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm). PCB layout and assembly processes require no modification.

Q: Do all parts meet RoHS and REACH requirements?

A: Yes. All three parts are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory standards.

Q: Which part should I select for automotive applications?

A: The Panasonic ERJ-6ENF38R3V carries AEC-Q200 automotive qualification. However, all three parts operate within the same temperature range (-55°C ~ 155°C) and meet equivalent compliance standards. Application-specific requirements should determine final selection.

Q: Can I use RC0805FR-0738R3L in place of RCS2012F38R3CS?

A: Yes. The YAGEO RC0805FR-0738R3L is electrically and mechanically equivalent. It features moisture-resistant properties and maintains identical resistance, tolerance, power rating, and operating temperature specifications.

Q: What is the significance of MSL Level 1?

A: Moisture Sensitivity Level 1 (Unlimited) indicates the component has no moisture sensitivity restrictions. These parts can be stored indefinitely without special moisture control measures and do not require baking before reflow soldering.
