Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RCS2012F9094CS are qualified based on the following criteria:

Electrical Parameters (Must Match):

• Resistance value: 9.09 MOhms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C

Mechanical Parameters (Must Match):

• Package type: 0805 (2012 Metric)
• Number of terminations: 2
• Physical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm)

Compliance Parameters (Must Match):

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

All identified substitute parts meet these criteria and are therefore electrically and mechanically interchangeable with the RCS2012F9094CS in applications requiring these specifications.

Frequently Asked Questions (FAQ)

Q: Can CRCW08059M09FKEA replace RCS2012F9094CS in any application?

A: Yes. Both parts share identical electrical specifications (9.09 MOhms ±1%, 0.125W, ±100ppm/°C, -55°C to 155°C), mechanical dimensions (0805 package, 2.00mm x 1.25mm), and compliance ratings (ROHS3, MSL 1). The CRCW08059M09FKEA has a lower maximum seated height (0.020" vs 0.026"), which may be advantageous in space-constrained PCB layouts.

Q: What is the difference between the three substitute parts?

A: The primary differences are manufacturer origin, specific environmental features, and maximum seated height. RCS2012F9094CS includes anti-sulfur properties; CRCW08059M09FKEA carries AEC-Q200 automotive qualification; RC0805FR-079M09L emphasizes moisture resistance. All three are electrically and mechanically equivalent.

Q: Are these parts suitable for automotive applications?

A: CRCW08059M09FKEA is explicitly qualified to AEC-Q200 automotive standard. RCS2012F9094CS and RC0805FR-079M09L are not specified with automotive qualification but meet the same electrical and environmental operating parameters.

Q: What does MSL 1 (Unlimited) mean for these resistors?

A: MSL 1 indicates the lowest moisture sensitivity level, meaning these parts have unlimited shelf life and do not require special moisture-controlled storage or handling procedures.

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

A: Yes. All three parts are 0805 package with identical electrical specifications and compliance ratings. The minor differences in maximum seated height (0.020" to 0.026") are within standard PCB assembly tolerances and do not affect interchangeability.

Q: What is the significance of the ±100ppm/°C temperature coefficient?

A: This specification indicates the resistance value will change by approximately 100 parts per million for each degree Celsius change in operating temperature. All three substitute parts share this specification, ensuring consistent performance across the -55°C to 155°C operating range.
