Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC2012F1R3CS are qualified based on strict electrical and mechanical parameter matching. All substitute candidates must satisfy the following criteria:

Mandatory Matching Parameters:

• Resistance Value: 1.3 Ohms (exact match)
• Tolerance: ±1% (exact match)
• Power Rating: 0.125W / 1/8W (exact match)
• Package / Case: 0805 (2012 Metric) (exact match)
• Composition: Thick Film (exact match)
• Operating Temperature Range: -55°C ~ 155°C (exact match)
• RoHS3 Compliance: Required
• MSL Rating: 1 (Unlimited) (exact match)

Allowable Variation Parameters:

• Temperature Coefficient: ±200ppm/°C to ±300ppm/°C (within acceptable tolerance drift)
• Height - Seated (Max): 0.024" to 0.026" (within PCB assembly clearance)
• Manufacturer: Different manufacturers permitted if all electrical and mechanical specifications align

The two substitute parts identified below meet all mandatory matching criteria and are therefore direct functional equivalents for the RC2012F1R3CS.

Parameter Comparison

Engineering Selection Recommendations

RC0805FR-071R3L (YAGEO): This substitute part is functionally equivalent to the RC2012F1R3CS with identical electrical specifications and package dimensions. The YAGEO RC0805FR-071R3L features a lower temperature coefficient (±200ppm/°C versus ±300ppm/°C), which provides improved temperature stability. Seated height is 0.024" compared to 0.026", offering slightly reduced profile for space-constrained applications. Both parts maintain Active product status, full RoHS3 compliance, and MSL 1 rating. Inventory availability is significantly higher for the YAGEO part (24,605 units in stock).

RMCF0805FT1R30 (Stackpole Electronics Inc): This substitute part meets all mandatory electrical and mechanical parameters with identical specifications to the RC2012F1R3CS. The Stackpole RMCF0805FT1R30 includes Automotive AEC-Q200 qualification, which certifies suitability for automotive applications requiring enhanced reliability standards. Temperature coefficient is ±200ppm/°C, matching the YAGEO alternative. Seated height is 0.026", identical to the Samsung original. Both parts maintain Active product status, full RoHS3 compliance, and MSL 1 rating. Inventory availability is 14,388 units in stock.

All three parts are suitable for direct substitution based on provided specifications. Selection between alternatives depends on application-specific requirements: standard industrial applications may use either YAGEO or Stackpole options; automotive applications requiring AEC-Q200 certification should specify the Stackpole RMCF0805FT1R30; space-constrained designs may benefit from the lower profile YAGEO RC0805FR-071R3L.

Frequently Asked Questions (FAQ)

Q: Can RC0805FR-071R3L replace RC2012F1R3CS in any application?

A: Yes. The RC0805FR-071R3L meets all mandatory electrical parameters (1.3 Ohms ±1%, 0.125W, 0805 package, thick film composition, -55°C to 155°C operating range) and regulatory requirements (RoHS3, MSL 1). The lower temperature coefficient (±200ppm/°C) provides improved stability. The 0.002" height reduction (0.024" versus 0.026") is within standard PCB assembly tolerances and does not affect footprint compatibility.

Q: What is the difference between RMCF0805FT1R30 and RC0805FR-071R3L?

A: Both parts are electrically and mechanically equivalent to RC2012F1R3CS. The primary distinction is that RMCF0805FT1R30 carries Automotive AEC-Q200 qualification, certifying enhanced reliability for automotive environments. Both feature ±200ppm/°C temperature coefficient. RMCF0805FT1R30 seated height is 0.026" (matching Samsung original); RC0805FR-071R3L is 0.024". Selection depends on application requirements and AEC-Q200 necessity.

Q: Are all three parts available in Tape & Reel packaging?

A: Yes. RC2012F1R3CS, RC0805FR-071R3L, and RMCF0805FT1R30 are all supplied in Tape & Reel (TR) packaging format, suitable for automated pick-and-place assembly processes.

Q: Do substitute parts maintain the same moisture resistance properties?

A: Yes. All three parts are specified as Moisture Resistant with MSL 1 (Unlimited) rating, indicating no moisture sensitivity limitations for storage and handling. REACH status is REACH Unaffected for all parts.

Q: Which substitute part has the best inventory availability?

A: RC0805FR-071R3L (YAGEO) has the highest inventory with 24,605 units in stock, compared to 14,388 units for RMCF0805FT1R30 and 801 units for the original RC2012F1R3CS.

Q: Can these parts be used interchangeably on the same PCB?

A: Yes. All three parts share identical 0805 (2012 Metric) package footprints (0.079" L x 0.049" W / 2.00mm x 1.25mm) and two-termination configurations. Seated heights (0.024" to 0.026") are within standard PCB assembly clearance specifications, permitting direct substitution without design modification.
