Substitute Part Grouping Explanation

Substitute parts for the RC1005F1R0CS are qualified based on strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Resistance value: 1 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.063W / 1/16W (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)
• Composition: Thick Film (exact match required)

Mechanical Equivalence Criteria:

• Package / Case: 0402 (1005 Metric) (exact match required)
• Physical dimensions: 0.039" L x 0.020" W / 1.00mm x 0.50mm (exact match required)
• Height - Seated (Max): 0.016" / 0.40mm (exact match required)
• Number of terminations: 2 (exact match required)

Compliance Equivalence Criteria:

• RoHS Status: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)
• REACH Status: REACH Unaffected (exact match required)

All identified substitute parts meet these criteria and are therefore suitable for direct replacement in applications where the RC1005F1R0CS is specified.

Parameter Comparison

Engineering Selection Recommendations

All three parts—RC1005F1R0CS, RC0402FR-071RL, and RMCF0402FT1R00—are functionally equivalent for applications requiring a 1 Ohm ±1% thick film chip resistor in 0402 package format. Selection between these parts is determined by availability, packaging preference, and application-specific requirements.

RC1005F1R0CS (Samsung Electro-Mechanics): Suitable for general-purpose applications. Maintains Active product status with standard moisture-resistant thick film construction. Temperature coefficient of ±300ppm/°C is within specification for the 0402 1 Ohm category.

RC0402FR-071RL (YAGEO): Suitable for general-purpose applications with preference for Cut Tape or Digi-Reel® packaging. Maintains Active product status with improved temperature coefficient of ±200ppm/°C, providing tighter thermal stability compared to the Samsung part. Higher inventory availability (3200 Pcs) supports rapid procurement.

RMCF0402FT1R00 (Stackpole Electronics Inc): Suitable for automotive and mission-critical applications. Maintains Active product status with Automotive AEC-Q200 qualification, indicating compliance with automotive reliability and quality standards. Temperature coefficient of ±200ppm/°C matches YAGEO performance. Highest inventory availability (33305 Pcs) supports large-volume procurement. Tape & Reel packaging aligns with high-volume assembly processes.

All parts maintain ROHS3 compliance, REACH Unaffected status, and MSL 1 (Unlimited) moisture sensitivity level, ensuring regulatory and environmental compatibility across applications.

Frequently Asked Questions (FAQ)

Q: Can RC0402FR-071RL replace RC1005F1R0CS in existing designs?

A: Yes. RC0402FR-071RL is electrically and mechanically equivalent to RC1005F1R0CS. Both parts share identical resistance (1 Ohm), tolerance (±1%), power rating (0.063W), package (0402), operating temperature range (-55°C ~ 155°C), and compliance certifications (ROHS3, REACH Unaffected, MSL 1). The primary difference is packaging format (Cut Tape & Digi-Reel® versus Tape & Reel) and temperature coefficient (±200ppm/°C versus ±300ppm/°C). The lower temperature coefficient of RC0402FR-071RL provides improved thermal stability.

Q: Is RMCF0402FT1R00 suitable for non-automotive applications?

A: Yes. RMCF0402FT1R00 is suitable for any application requiring a 1 Ohm ±1% thick film chip resistor in 0402 package. The Automotive AEC-Q200 qualification indicates enhanced reliability and quality assurance, making this part suitable for both automotive and non-automotive applications where high reliability is required. Electrical and mechanical specifications are identical to RC1005F1R0CS and RC0402FR-071RL.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging supplies components on continuous carrier tape wound on a reel, suitable for automated pick-and-place assembly equipment. Cut Tape (CT) packaging supplies components on cut segments of carrier tape, suitable for manual assembly or lower-volume production. Digi-Reel® is a proprietary packaging format combining benefits of both formats. Component specifications remain identical regardless of packaging format.

Q: Are all three parts suitable for high-temperature applications?

A: Yes. All three parts—RC1005F1R0CS, RC0402FR-071RL, and RMCF0402FT1R00—operate across -55°C to 155°C, supporting high-temperature applications within this range. Temperature coefficient specifications (±300ppm/°C for Samsung, ±200ppm/°C for YAGEO and Stackpole) define resistance value drift across the operating temperature range. Applications requiring minimal temperature-induced resistance variation should prioritize parts with lower temperature coefficients (±200ppm/°C).

Q: Do all substitute parts meet RoHS and REACH requirements?

A: Yes. RC1005F1R0CS, RC0402FR-071RL, and RMCF0402FT1R00 are all ROHS3 Compliant and REACH Unaffected, meeting regulatory requirements for restricted substance use and chemical safety across global markets.

Q: What is Moisture Sensitivity Level (MSL) 1?

A: MSL 1 indicates unlimited shelf life without moisture-related degradation. Components rated MSL 1 do not require special moisture-control storage or handling procedures, simplifying inventory management and reducing storage costs compared to higher MSL ratings.
