Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RMCS0805FT2K05 is determined by strict equivalence across the following critical parameters:

• Resistance value: 2.05 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.125W / 1/8W (exact match required)
• Package / Case: 0805 (2012 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)
• RoHS compliance: ROHS3 (exact match required)
• Moisture sensitivity: MSL 1 (exact match required)

All substitute parts listed meet these criteria. Variations in features (such as automotive AEC-Q200 qualification or moisture resistance) and physical dimensions (height-seated maximum) do not affect functional substitutability for applications where the base electrical and mechanical specifications are the primary requirement.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts are functionally equivalent to the RMCS0805FT2K05 based on electrical and mechanical specifications. Selection among these alternatives should be based on the following factors:

Automotive Applications: RMCF0805FT2K05, CRCW08052K05FKEA, and ERJ-6ENF2051V carry AEC-Q200 automotive qualification. These parts are suitable for applications requiring automotive-grade reliability standards.

General-Purpose Applications: RMCS0805FT2K05 (original) and RC0805FR-072K05L are suitable for non-automotive applications. The RC0805FR-072K05L features moisture-resistant composition.

Supply Chain Availability: ERJ-6ENF2051V and RC0805FR-072K05L demonstrate higher inventory levels (167,880 and 185,858 units respectively), providing greater availability for high-volume procurement.

Packaging Preference: RMCF0805FT2K05, CRCW08052K05FKEA, and ERJ-6ENF2051V are supplied in Tape & Reel (TR) packaging. RC0805FR-072K05L is supplied in Cut Tape (CT) & Digi-Reel® packaging.

All parts maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard PCB assembly processes.

Frequently Asked Questions (FAQ)

Q: Can RMCF0805FT2K05 replace RMCS0805FT2K05 in non-automotive applications?

A: Yes. RMCF0805FT2K05 meets all electrical and mechanical specifications of RMCS0805FT2K05. The AEC-Q200 automotive qualification is an additional feature that does not prevent use in general-purpose applications.

Q: What is the difference between anti-sulfur and moisture-resistant compositions?

A: Anti-sulfur composition (RMCS0805FT2K05) provides protection against sulfur contamination in the operating environment. Moisture-resistant composition (RC0805FR-072K05L) provides enhanced protection against moisture ingress. Both are thick film resistors with identical electrical specifications.

Q: Are all substitute parts pin-compatible with RMCS0805FT2K05?

A: Yes. All substitute parts use the 0805 (2012 Metric) package with 2 terminations, ensuring identical PCB footprint and pin compatibility.

Q: Does the height-seated maximum variation affect PCB assembly?

A: No. All parts have height-seated maximum values within 0.024" to 0.028" (0.60mm to 0.70mm), which is within standard PCB assembly tolerances for 0805 components. This variation does not affect functionality or assembly compatibility.

Q: Which substitute part offers the best supply chain availability?

A: ERJ-6ENF2051V and RC0805FR-072K05L offer the highest inventory levels at 167,880 and 185,858 units respectively, providing optimal availability for high-volume applications.

Q: Can I use these parts interchangeably on the same PCB?

A: Yes. All substitute parts are electrically and mechanically equivalent. They can be used interchangeably without circuit modification or re-qualification, provided the application does not have specific requirements for automotive qualification or particular packaging formats.
