RC1005J2R0CS Equivalent & Substitute Parts

Part Overview

The RC1005J2R0CS is a 2 Ohm ±5% thick film chip resistor manufactured by Samsung Electro-Mechanics in 0402 (1005 Metric) package format. This surface mount device is rated for 0.063W (1/16W) power dissipation and operates across the temperature range of -55°C to 155°C. The component is ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating and is currently in active production status with 954 pieces available in inventory.

Equivalent and substitute parts are identified based on matching electrical specifications (resistance value, tolerance, power rating) and mechanical compatibility (package size, termination count, physical dimensions). Alternative sources provide identical or enhanced performance characteristics while maintaining functional interchangeability within the specified parameter constraints.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1005J2R0CS is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 2 Ohms
• Package format: 0402 (1005 Metric)
• Physical dimensions: 0.039" L x 0.020" W (1.00mm x 0.50mm)
• Number of terminations: 2
• Composition: Thick Film
• Operating temperature range: -55°C to 155°C minimum
• RoHS compliance: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation Parameters:

• Tolerance: ±5% or tighter (±1% acceptable as upgrade)
• Temperature coefficient: ±300ppm/°C or better
• Power rating: 0.063W (1/16W) or higher
• Manufacturer: Any qualified source
• Additional certifications: AEC-Q200 automotive qualification acceptable as enhancement

The three substitute parts identified (RC0402JR-072RL, RMCF0402FT2R00, RMCF0402JT2R00) meet all mandatory parameters and are therefore functionally interchangeable with the primary part number.

Parameter Comparison

Engineering Selection Recommendations

RC0402JR-072RL (YAGEO): This substitute maintains identical electrical specifications to the primary part with ±5% tolerance and 0.063W power rating. The temperature coefficient is improved to ±200ppm/°C compared to the original ±300ppm/°C. All mechanical and compliance parameters are equivalent. This part is suitable for direct substitution in applications where automotive qualification is not required.

RMCF0402FT2R00 (Stackpole Electronics Inc): This substitute provides enhanced tolerance specification at ±1% compared to the original ±5%, while maintaining all other electrical and mechanical parameters. The component carries AEC-Q200 automotive qualification, indicating suitability for automotive-grade applications. Temperature coefficient is ±200ppm/°C. This part is appropriate for applications requiring tighter tolerance control or automotive compliance.

RMCF0402JT2R00 (Stackpole Electronics Inc): This substitute maintains the original ±5% tolerance specification with identical power rating and package format. The component carries AEC-Q200 automotive qualification and features improved temperature coefficient of ±200ppm/°C. This part provides automotive-grade reliability while preserving the original tolerance specification.

All three substitute parts are in active production status with substantial inventory availability. Selection between alternatives depends on application requirements for tolerance precision and automotive qualification needs.

Frequently Asked Questions (FAQ)

Q: Can RC0402JR-072RL replace RC1005J2R0CS in all applications?

A: RC0402JR-072RL is functionally interchangeable with RC1005J2R0CS. Both components share identical resistance value (2 Ohms), tolerance (±5%), power rating (0.063W), package format (0402), and operating temperature range (-55°C to 155°C). The substitute features improved temperature coefficient (±200ppm/°C versus ±300ppm/°C). Direct substitution is valid for non-automotive applications.

Q: What is the difference between RMCF0402FT2R00 and RMCF0402JT2R00?

A: Both Stackpole parts are AEC-Q200 qualified and share identical package, power rating, and operating temperature specifications. The primary difference is tolerance: RMCF0402FT2R00 provides ±1% tolerance while RMCF0402JT2R00 maintains ±5% tolerance. Selection depends on circuit requirements for tolerance precision. Both feature ±200ppm/°C temperature coefficient.

Q: Are the Stackpole parts suitable for automotive applications?

A: Yes. Both RMCF0402FT2R00 and RMCF0402JT2R00 carry AEC-Q200 automotive qualification, indicating compliance with automotive industry reliability and performance standards. These parts are appropriate for automotive-grade circuit designs.

Q: Do all substitute parts have the same physical dimensions?

A: Yes. All substitute parts maintain the 0402 (1005 Metric) package format with identical physical dimensions of 0.039" L x 0.020" W (1.00mm x 0.50mm) and maximum seated height of 0.016" (0.40mm). PCB layout and assembly processes require no modification.

Q: What is the moisture sensitivity rating for these components?

A: All parts including the primary RC1005J2R0CS and all three substitutes carry MSL 1 (Unlimited) moisture sensitivity level rating. This indicates unlimited shelf life without moisture control requirements.

Q: Are all parts RoHS compliant?

A: Yes. The primary part and all three substitute parts are ROHS3 compliant, meeting current environmental and regulatory requirements for electronic component manufacturing and use.

Q: Can I use RMCF0402FT2R00 (±1% tolerance) as a direct replacement for RC1005J2R0CS (±5% tolerance)?

A: Yes. RMCF0402FT2R00 is a direct replacement with enhanced tolerance specification. Tighter tolerance (±1%) is a performance upgrade that does not create compatibility issues. The component is functionally interchangeable and suitable for applications where the original ±5% tolerance was acceptable.
