Key Parameters

Substitute Part Grouping Explanation

Substitution of the RC3216J1R1CS is determined by strict equivalence in the following critical parameters:

Mandatory Equivalence Parameters:

• Resistance value: 1.1 Ohms
• Power rating: 0.25W (1/4W)
• Package: 1206 (3216 Metric)
• Composition: Thick Film
• Operating temperature range: -55°C ~ 155°C
• Moisture resistance: Required
• RoHS3 compliance: Required
• MSL rating: 1 (Unlimited)

Allowable Variation Parameters:

• Tolerance: ±5% (main part) to ±1% (substitute parts with improved tolerance)
• Temperature coefficient: ±300ppm/°C (main part) to ±200ppm/°C (substitute parts with improved stability)
• Packaging format: Tape & Reel (TR) acceptable for substitute parts
• Automotive qualification: AEC-Q200 available in substitute options

Substitute parts RC1206FR-071R1L, RC1206JR-071R1L, RMCF1206FT1R10, and RMCF1206JT1R10 meet all mandatory equivalence criteria and are therefore direct substitutes for the RC3216J1R1CS.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitution (Tolerance-Matched): RC1206JR-071R1L (YAGEO) is the direct equivalent to RC3216J1R1CS, maintaining ±5% tolerance specification. This part is suitable for applications where the original tolerance specification must be preserved. YAGEO RC_L series provides equivalent performance with higher inventory availability (5062 pieces).

Upgraded Substitution (Improved Tolerance): RC1206FR-071R1L (YAGEO) and RMCF1206FT1R10 (Stackpole) offer ±1% tolerance with improved temperature coefficient (±200ppm/°C versus ±300ppm/°C). These parts are suitable for applications requiring tighter resistance tolerance and enhanced temperature stability while maintaining all other electrical and mechanical specifications.

Automotive-Grade Substitution: RMCF1206JT1R10 (Stackpole) and RMCF1206FT1R10 (Stackpole) carry AEC-Q200 automotive qualification. These parts are required for automotive applications and meet all electrical specifications of the RC3216J1R1CS. RMCF1206JT1R10 maintains ±5% tolerance; RMCF1206FT1R10 provides ±1% tolerance.

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and identical operating temperature range (-55°C ~ 155°C). Selection should be based on application requirements for tolerance, automotive qualification, and sourcing availability.

Frequently Asked Questions (FAQ)

Q: Can RC1206FR-071R1L replace RC3216J1R1CS in all applications?

A: RC1206FR-071R1L is a direct substitute with improved tolerance (±1% versus ±5%). It meets all mandatory electrical and mechanical specifications. Applications sensitive to tolerance specification should confirm that ±1% tolerance is acceptable. All other parameters are equivalent.

Q: What is the difference between YAGEO RC1206 series and Stackpole RMCF1206 series substitutes?

A: Both series meet the core electrical specifications. YAGEO RC_L series (RC1206FR-071R1L, RC1206JR-071R1L) are standard industrial-grade components. Stackpole RMCF series (RMCF1206FT1R10, RMCF1206JT1R10) carry AEC-Q200 automotive qualification and are required for automotive applications. Temperature coefficient is ±200ppm/°C for both manufacturers versus ±300ppm/°C for the original Samsung part.

Q: Are there package compatibility concerns when substituting?

A: All substitute parts use the 1206 (3216 Metric) package with identical footprint and mounting requirements. Substitute parts are supplied in Tape & Reel (TR) format, which is standard for automated assembly. No PCB layout or assembly process changes are required.

Q: Which substitute part should be selected for automotive applications?

A: RMCF1206JT1R10 (±5% tolerance) or RMCF1206FT1R10 (±1% tolerance) must be used for automotive applications. Both carry AEC-Q200 qualification. Selection between these two depends on tolerance requirements: RMCF1206JT1R10 matches the original ±5% specification; RMCF1206FT1R10 provides improved ±1% tolerance.

Q: Is the improved temperature coefficient (±200ppm/°C) of substitute parts beneficial?

A: The improved temperature coefficient of ±200ppm/°C in substitute parts provides enhanced stability across the operating temperature range (-55°C ~ 155°C) compared to the original ±300ppm/°C specification. This is beneficial for precision applications but not required for general-purpose use.

Q: What inventory considerations apply to these substitutes?

A: RMCF1206JT1R10 has the highest inventory (6830 pieces), followed by RC1206FR-071R1L (5300 pieces) and RC1206JR-071R1L (5062 pieces). RMCF1206FT1R10 has lower availability (959 pieces). Sourcing decisions should account for lead time and volume requirements.
