Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RMCS1206FT3K01 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 3.01 kOhms
• Tolerance: ±1%
• Package / Case: 1206 (3216 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• Number of Terminations: 2

Allowable Variations:

• Power rating may be equal or higher (0.25W minimum)
• Packaging format may differ (Tape & Reel, Cut Tape, Digi-Reel)
• Manufacturer may vary
• Additional features (automotive qualification, moisture resistance, pulse withstanding) are permissible enhancements
• RoHS and REACH compliance status may vary

All substitute parts listed maintain electrical equivalence through identical resistance, tolerance, temperature coefficient, and operating range specifications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Status, ROHS3 Compliant):

RMCF1206FT3K01 from Stackpole Electronics Inc is the manufacturer-recommended substitute. It maintains identical electrical specifications while adding automotive AEC-Q200 qualification. This part is preferred for designs requiring automotive-grade reliability with 102,594 units in stock.

CRCW12063K01FKEA and CRCW12063K01FKTA from Vishay Dale are functionally equivalent with automotive AEC-Q200 qualification. CRCW12063K01FKEA maintains ROHS3 compliance with 35,512 units available. CRCW12063K01FKTA is non-compliant with RoHS regulations and should be selected only when legacy designs explicitly require this variant.

AC1206FR-073K01L from YAGEO combines automotive AEC-Q200 qualification with moisture-resistant construction, offering enhanced environmental protection with 5,826 units in stock.

CR1206-FX-3011ELF from Bourns Inc. provides moisture-resistant thick film construction without automotive qualification, suitable for general industrial applications with 53,686 units available.

RC1206FR-073K01L from YAGEO offers moisture-resistant construction in Cut Tape packaging format with 5,387 units in stock.

Enhanced Power Rating Option:

CRCW12063K01FKEAHP from Vishay Dale provides 0.75W power rating in the same 1206 package with automotive AEC-Q200 and pulse withstanding features. This part is suitable for applications requiring higher power dissipation capacity with 47,928 units in stock.

Legacy Status:

ERJ-8ENF3011V from Panasonic Electronic Components is marked "Not For New Designs" and should be used only for replacement or maintenance of existing designs. This part maintains ROHS3 compliance and automotive AEC-Q200 qualification with 20,400 units available.

Frequently Asked Questions (FAQ)

Q: Can RMCF1206FT3K01 directly replace RMCS1206FT3K01?

A: Yes. Both parts share identical electrical specifications: 3.01 kOhms ±1%, 0.25W power rating, ±100ppm/°C temperature coefficient, and -55°C to 155°C operating range. RMCF1206FT3K01 adds automotive AEC-Q200 qualification as an enhancement. The 1206 package dimensions are compatible for PCB layout purposes.

Q: What is the difference between automotive AEC-Q200 qualified parts and non-qualified parts?

A: Automotive AEC-Q200 qualification indicates the part has undergone rigorous testing for automotive applications including thermal cycling, mechanical shock, and reliability validation. Parts with this qualification (RMCF1206FT3K01, AC1206FR-073K01L, CRCW12063K01FKEA, CRCW12063K01FKTA, ERJ-8ENF3011V) are suitable for automotive and high-reliability industrial designs. Non-qualified parts (RMCS1206FT3K01, CR1206-FX-3011ELF, RC1206FR-073K01L) are suitable for general industrial and consumer applications.

Q: Are there packaging format differences between substitutes?

A: Yes. Most substitutes are supplied in Tape & Reel (TR) format. CRCW12063K01FKEA is available in Cut Tape (CT) & Digi-Reel format, and RC1206FR-073K01L is supplied in Cut Tape format. These packaging differences affect handling and assembly processes but do not impact electrical performance or PCB compatibility.

Q: Can CRCW12063K01FKEAHP with 0.75W rating replace the 0.25W RMCS1206FT3K01?

A: Yes. Higher power rating parts are electrically compatible substitutes. The 0.75W rating provides additional thermal margin and is suitable for applications where the original 0.25W specification is marginal. The 1206 package dimensions remain identical, ensuring PCB compatibility.

Q: Why is CRCW12063K01FKTA marked as RoHS non-compliant?

A: CRCW12063K01FKTA does not meet ROHS3 compliance requirements. This part should be selected only when existing designs explicitly require this specific variant or when legacy system compatibility is mandatory. For new designs, ROHS3 compliant alternatives are available.

Q: Should ERJ-8ENF3011V be used in new designs?

A: No. ERJ-8ENF3011V is marked "Not For New Designs" by Panasonic Electronic Components. This designation indicates the part is in end-of-life status. Use this part only for replacement or maintenance of existing designs. For new designs, select from active status alternatives such as RMCF1206FT3K01, AC1206FR-073K01L, or CRCW12063K01FKEA.

Q: What does Moisture Sensitivity Level 1 (Unlimited) mean?

A: MSL 1 (Unlimited) indicates the component has no moisture sensitivity restrictions. The part can be stored indefinitely without special humidity control and does not require baking before soldering. All listed substitutes maintain this MSL 1 rating.

Q: Are all substitutes ROHS3 compliant?

A: No. CRCW12063K01FKTA is RoHS non-compliant. All other substitutes (RMCF1206FT3K01, AC1206FR-073K01L, CR1206-FX-3011ELF, CRCW12063K01FKEA, CRCW12063K01FKEAHP, ERJ-8ENF3011V, RC1206FR-073K01L) are ROHS3 compliant. Verify compliance requirements for your application before selecting a substitute.
