Key Parameters

Substitute Part Grouping Explanation

Substitution of the RC2012J1R6CS is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Resistance value: 1.6 Ohms (exact match required)
• Package format: 0805 (2012 Metric) (exact match required)
• Power rating: 0.125W minimum (1/8W)
• Composition: Thick Film
• Operating temperature range: -55°C to 155°C minimum
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1 or better

Secondary Substitution Criteria:

• Tolerance: ±5% or tighter (±1% is acceptable as an upgrade)
• Temperature coefficient: ±300ppm/°C or better
• Termination count: 2 (exact match)

All identified substitute parts meet or exceed the primary criteria. Tolerance improvements and automotive-grade certifications represent enhanced specifications rather than functional limitations.

Parameter Comparison

Engineering Selection Recommendations

RC0805JR-071R6L (YAGEO): This substitute maintains identical electrical specifications to the RC2012J1R6CS with ±5% tolerance and 0.125W power rating. The YAGEO part offers improved temperature coefficient performance (±200ppm/°C versus ±300ppm/°C) while maintaining full ROHS3 compliance and MSL 1 rating. Seated height is marginally reduced (0.024" versus 0.026"), which may provide advantages in space-constrained applications. This part is suitable for direct substitution in non-automotive applications.

RMCF0805FT1R60 (Stackpole Electronics Inc): This substitute provides enhanced tolerance specification at ±1% compared to the original ±5% tolerance. The part carries AEC-Q200 automotive qualification, making it suitable for automotive and high-reliability applications. Temperature coefficient is improved to ±200ppm/°C. All other electrical and mechanical parameters remain compatible with the RC2012J1R6CS. This part represents an upgrade path for applications requiring tighter tolerance control or automotive-grade components.

RMCF0805JT1R60 (Stackpole Electronics Inc): This substitute maintains the ±5% tolerance specification of the original part while providing AEC-Q200 automotive qualification. Temperature coefficient is improved to ±200ppm/°C. The part is fully compatible with the RC2012J1R6CS in all critical electrical and mechanical parameters. This part is recommended for automotive applications requiring equivalent tolerance specifications to the original component.

Frequently Asked Questions (FAQ)

Q: Can RC0805JR-071R6L be used as a direct replacement for RC2012J1R6CS?

A: Yes. Both parts share identical resistance (1.6 Ohms), tolerance (±5%), power rating (0.125W), package format (0805), and operating temperature range (-55°C to 155°C). The YAGEO part offers improved temperature coefficient (±200ppm/°C) and maintains full ROHS3 and MSL 1 compliance. The marginal difference in seated height (0.024" versus 0.026") is within standard PCB design tolerances.

Q: What is the difference between RMCF0805FT1R60 and RMCF0805JT1R60?

A: Both Stackpole parts are AEC-Q200 qualified and share identical resistance, power rating, package format, and operating temperature range. The primary difference is tolerance specification: RMCF0805FT1R60 provides ±1% tolerance, while RMCF0805JT1R60 provides ±5% tolerance. Selection depends on circuit requirements for tolerance control.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. RC0805JR-071R6L, RMCF0805FT1R60, and RMCF0805JT1R60 are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the compliance profile of the RC2012J1R6CS.

Q: Can automotive-grade parts (Stackpole RMCF series) be used in non-automotive applications?

A: Yes. Automotive-grade components meet or exceed the performance and reliability requirements of non-automotive applications. AEC-Q200 qualification represents enhanced qualification testing and does not restrict use in non-automotive circuits.

Q: What is the significance of temperature coefficient differences between these parts?

A: Temperature coefficient indicates resistance value drift across the operating temperature range. The RC2012J1R6CS has ±300ppm/°C, while substitute parts offer ±200ppm/°C. Lower temperature coefficient values indicate better resistance stability across temperature variations. For applications with strict resistance tolerance requirements across temperature extremes, the improved temperature coefficient of substitute parts provides enhanced performance.

Q: Are there package or footprint compatibility concerns between these parts?

A: All parts use the 0805 (2012 Metric) package format with identical length and width (0.079" L x 0.049" W / 2.00mm x 1.25mm). Seated height varies slightly: RC2012J1R6CS and Stackpole parts are 0.026" (0.65mm), while RC0805JR-071R6L is 0.024" (0.60mm). These variations are within standard PCB design tolerances and do not affect footprint compatibility.

Q: What inventory considerations apply to these substitute parts?

A: RC0805JR-071R6L (YAGEO) has 2105 pieces in stock, RMCF0805FT1R60 (Stackpole) has 11515 pieces in stock, and RMCF0805JT1R60 (Stackpole) has 1061 pieces in stock. Availability levels may influence sourcing decisions for high-volume applications.
