Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RMCS0805FT2R20 is determined by strict equivalence across the following critical parameters:

• Resistance value: 2.2 Ohms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Package: 0805 (2012 Metric)
• Composition: Thick Film
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C ~ 155°C
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

All identified substitute parts meet these core electrical and mechanical parameters. Variations in packaging format (Tape & Reel vs. Cut Tape), manufacturer features (automotive qualification, moisture resistance), and physical height tolerances do not affect functional equivalence in standard applications.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts—AC0805FR-072R2L, CRCW08052R20FNEA, and RC0805FR-072R2L—are functionally equivalent to the RMCS0805FT2R20 based on core electrical and mechanical specifications. Selection among these alternatives should be based on:

• Packaging availability and supply chain requirements
• Automotive qualification status (AC0805FR-072R2L and CRCW08052R20FNEA carry AEC-Q200 certification; RMCS0805FT2R20 and RC0805FR-072R2L do not)
• Inventory levels and lead times from respective manufacturers
• Physical height constraints in space-limited PCB designs (CRCW08052R20FNEA has maximum seated height of 0.020", compared to 0.024" for other variants)

All parts maintain ROHS3 compliance and unlimited moisture sensitivity rating, ensuring compatibility with standard manufacturing and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can AC0805FR-072R2L be used as a direct replacement for RMCS0805FT2R20?

A: Yes. Both parts share identical electrical specifications (2.2 Ohms ±1%, 0.125W, ±200ppm/°C, -55°C to 155°C) and 0805 package dimensions. AC0805FR-072R2L includes automotive AEC-Q200 qualification and moisture resistance features not present in the original part, but these do not prevent substitution in standard applications.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging supplies components on continuous carrier tape wound on reels, suitable for high-volume automated assembly. Cut Tape (CT) & Digi-Reel® packaging provides components on cut tape segments, typically used for lower-volume orders or manual assembly. Both formats contain identical components; packaging format selection depends on assembly process requirements.

Q: Does the height difference between CRCW08052R20FNEA (0.020") and other variants (0.024") affect compatibility?

A: Height variation of 0.004" (0.10mm) is within standard PCB design tolerances for 0805 components. CRCW08052R20FNEA may be preferred in space-constrained designs with tight vertical clearance requirements. Verify PCB design specifications before selecting based on height alone.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. RMCS0805FT2R20, AC0805FR-072R2L, CRCW08052R20FNEA, and RC0805FR-072R2L are all ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1), meeting standard environmental and regulatory requirements.

Q: Which substitute part has the highest inventory availability?

A: RC0805FR-072R2L (YAGEO) has 77,251 pieces in stock, followed by AC0805FR-072R2L (YAGEO) with 42,343 pieces, and CRCW08052R20FNEA (Vishay Dale) with 13,761 pieces. Inventory levels should be verified with suppliers for current availability.
