Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RCS2012F48R7CS are qualified based on the following criteria:

Electrical Equivalence: Resistance value of 48.7 Ohms with ±1% tolerance, power rating of 0.125W (1/8W), temperature coefficient of ±100ppm/°C, and operating temperature range of -55°C ~ 155°C.

Mechanical Compatibility: 0805 (2012 Metric) package format with 2 terminations and compatible physical dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm).

Compliance Requirements: ROHS3 compliance, Moisture Sensitivity Level 1 (Unlimited), REACH Unaffected status, and EAR99 ECCN classification.

Composition: Thick film construction matching the original component.

All identified substitute parts meet these criteria and are classified as Active product status.

Parameter Comparison

Engineering Selection Recommendations

All four components listed—RCS2012F48R7CS (Samsung Electro-Mechanics), CRCW080548R7FKEA (Vishay Dale), ERJ-6ENF48R7V (Panasonic Electronic Components), and RC0805FR-0748R7L (YAGEO)—are Active product status and fully compliant with ROHS3 requirements. Each component maintains identical electrical specifications (48.7 Ohms ±1%, 0.125W, ±100ppm/°C, -55°C ~ 155°C operating range) and mechanical compatibility within the 0805 package format.

The CRCW080548R7FKEA and ERJ-6ENF48R7V variants include AEC-Q200 automotive qualification, which provides additional reliability assurance for automotive applications. The RC0805FR-0748R7L and RCS2012F48R7CS feature moisture-resistant construction without automotive-specific ratings.

Height variations exist among the substitute parts (ranging from 0.020" to 0.028" seated height), which may be relevant for applications with strict PCB clearance constraints. All components maintain MSL 1 (Unlimited) moisture sensitivity classification and REACH Unaffected status, ensuring compliance with environmental and regulatory standards.

Frequently Asked Questions (FAQ)

Q: Can CRCW080548R7FKEA replace RCS2012F48R7CS in non-automotive applications?

A: Yes. The CRCW080548R7FKEA meets all electrical and mechanical specifications required for direct substitution. The AEC-Q200 automotive qualification is an additional feature that does not restrict use in non-automotive circuits.

Q: What is the significance of the height difference between substitute parts?

A: Seated height variations (0.020" to 0.028") may affect PCB layout in applications with limited vertical clearance. Verify PCB design constraints before selection. All parts remain within 0805 package specifications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. RCS2012F48R7CS, CRCW080548R7FKEA, ERJ-6ENF48R7V, and RC0805FR-0748R7L are all ROHS3 compliant with REACH Unaffected status.

Q: What is the difference between anti-sulfur and AEC-Q200 features?

A: Anti-sulfur construction (RCS2012F48R7CS, RC0805FR-0748R7L) provides protection against sulfur corrosion in specific environments. AEC-Q200 (CRCW080548R7FKEA, ERJ-6ENF48R7V) is an automotive industry qualification standard covering reliability and performance testing. These are distinct feature sets; AEC-Q200 parts do not inherently include anti-sulfur treatment.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes. All four components share identical electrical specifications, tolerance, power rating, temperature coefficient, operating temperature range, and 0805 package format. Physical dimensions and termination count are equivalent, enabling direct substitution in PCB designs.

Q: What does MSL 1 (Unlimited) mean for moisture sensitivity?

A: MSL 1 indicates the lowest moisture sensitivity level, allowing unlimited shelf life without special moisture control measures during storage and handling.
