Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1005F2803CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 280 kOhms
• Tolerance: ±1%
• Package / Case: 0402 (1005 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• Moisture Sensitivity Level: 1 (Unlimited)
• RoHS Status: ROHS3 Compliant

Allowable Variation:

• Power Rating: Substitute parts may equal or exceed the 0.063W (1/16W) specification
• Features: Substitute parts may include additional certifications (such as Automotive AEC-Q200) or enhanced moisture resistance without affecting base functionality

Substitute parts are grouped into three categories based on their relationship to the main part:

Direct Substitutes maintain identical electrical and mechanical specifications with no enhancement or reduction in rated parameters.

Upgrade Substitutes provide enhanced power ratings or additional certifications while maintaining all other critical parameters.

Similar Substitutes include automotive-grade certifications or enhanced features while maintaining electrical equivalence.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Electrical and Mechanical Equivalence):

The CR0402-FX-2803GLF (Bourns Inc.) and RC0402FR-07280KL (YAGEO) are direct functional equivalents to the RC1005F2803CS. Both parts maintain identical resistance, tolerance, power rating, package dimensions, and temperature specifications. The RC0402FR-07280KL offers significantly higher inventory availability (264,508 units) compared to the main part. Both parts are ROHS3 compliant with MSL 1 rating and are suitable for direct replacement in applications where the original part is unavailable.

Upgrade Substitute (Enhanced Power Rating):

The ERJ-2RKF2803X (Panasonic Electronic Components) provides an upgrade path with a higher power rating of 0.1W (1/10W) while maintaining all other electrical parameters. This part includes Automotive AEC-Q200 certification and is suitable for applications requiring enhanced thermal performance or automotive-grade reliability. The upgrade is backward-compatible for circuits designed around the 0.063W specification.

Similar Substitutes (Automotive-Grade Alternatives):

The AC0402FR-07280KL (YAGEO), CRCW0402280KFKED (Vishay Dale), and RMCF0402FT280K (Stackpole Electronics Inc) are functionally equivalent parts with Automotive AEC-Q200 certification. These parts maintain the 0.063W power rating and all electrical specifications of the main part while adding automotive-grade reliability qualifications. Selection among these alternatives depends on inventory availability and supply chain preferences. The RMCF0402FT280K offers the highest inventory level (176,036 units) among automotive-qualified options.

All substitute parts are ROHS3 compliant, operate across the identical temperature range (-55°C ~ 155°C), and maintain MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard PCB assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the CR0402-FX-2803GLF replace the RC1005F2803CS in any application?

A: Yes. The CR0402-FX-2803GLF is a direct electrical and mechanical equivalent. Both parts share identical resistance (280 kOhms), tolerance (±1%), power rating (0.063W), package (0402), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C). Direct substitution is valid without circuit modification.

Q: What is the difference between the RC0402FR-07280KL and the RC1005F2803CS?

A: The RC0402FR-07280KL is manufactured by YAGEO rather than Samsung Electro-Mechanics, but all electrical and mechanical parameters are identical. Both parts are moisture-resistant thick film resistors with ROHS3 compliance and MSL 1 rating. The primary difference is manufacturer and inventory availability.

Q: Can I use the ERJ-2RKF2803X as a substitute if my circuit is designed for 0.063W?

A: Yes. The ERJ-2RKF2803X has a higher power rating (0.1W) than the original specification (0.063W). A higher power rating is backward-compatible and will not cause circuit malfunction. The part will operate safely in applications designed for the lower power specification.

Q: What does Automotive AEC-Q200 certification mean for the AC0402FR-07280KL, CRCW0402280KFKED, and RMCF0402FT280K?

A: Automotive AEC-Q200 certification indicates that these parts meet automotive industry reliability and quality standards. These parts are qualified for automotive applications and undergo additional testing and qualification processes. They are suitable for both automotive and general industrial applications.

Q: Are all substitute parts available in Tape & Reel (TR) packaging?

A: Yes. All substitute parts listed are supplied in Tape & Reel (TR) packaging, matching the packaging format of the RC1005F2803CS. This ensures compatibility with standard automated PCB assembly equipment.

Q: Which substitute part has the highest inventory availability?

A: The RC0402FR-07280KL (YAGEO) has the highest inventory with 264,508 units in stock, followed by the RMCF0402FT280K (Stackpole Electronics Inc) with 176,036 units. Both parts are suitable for high-volume production requirements.

Q: Do all substitute parts have the same moisture sensitivity level?

A: Yes. All substitute parts maintain MSL 1 (Unlimited) moisture sensitivity level, identical to the RC1005F2803CS. This ensures compatibility with standard PCB assembly and storage procedures without requiring special moisture control measures.

Q: Can I mix different manufacturers' parts in the same production batch?

A: Yes. All substitute parts meet identical electrical specifications (280 kOhms ±1%, 0.063W or higher, 0402 package) and are ROHS3 compliant with MSL 1 rating. Parts from different manufacturers can be used interchangeably within the same circuit design.
