Viking Tech
A direct upgrade from the same manufacturer with tighter tolerance, matching all other key parameters.
Find and compare alternatives for the Viking Tech ARG05FTC1004, a 1MΩ 1% 0.125W 0805 thin film resistor. This guide reviews pin-compatible upgrades and parametric alternatives, highlighting key differences in tolerance and temperature coefficient (TCR).
Risk of performance degradation if a lower-spec TCR/technology part is used in a precision circuit.
All reviewed candidates share the same 0805 package, ensuring physical compatibility.
Yes, ARG05BTC1004 is a direct upgrade replacement. For general-purpose use, several thick-film resistors like Yageo's AC0805FR-071ML are form-fit compatible but have weaker performance.
The best path is an upgrade to ARG05BTC1004 from the same manufacturer, offering tighter ±0.1% tolerance with identical form, fit, and function.
The main risk when substituting is using a thick-film resistor with a higher TCR (e.g., ±100ppm/°C) in a circuit that requires the stability of the original ±25ppm/°C thin-film part.

| Feature / factor | ARG05FTC1004 | ARG05BTC1004 | AC0805FR-071ML | Alt 3 | Compatibility / risk |
|---|---|---|---|---|---|
| Package | 0805 | 0805 | 0805 | 0805 — Identical package and pin count.; AC0805FR-071ML: Identical package and pin count. | |
| Resistance | 1MΩ | 1MΩ | - | 1MΩ — Resistance value is identical. | |
| Tolerance | ±1.0% | ±0.1% | - | ±0.1% — Candidate has tighter tolerance. | |
| Tcr | ±25 ppm/°C | ±25ppm/°C | ±100 ppm/°C | ±25ppm/°C / ±100 ppm/°C — Identical precision TCR.; AC0805FR-071ML: Candidate has 4x higher TCR, impacting stability. | |
| Technology | Thin Film | Thin Film | Thick Film | Thin Film / Thick Film — Both are precision thin film resistors.; AC0805FR-071ML: General purpose thick film vs precision thin film. |
The best alternative is Viking Tech's ARG05BTC1004, which is an upgrade with tighter tolerance (±0.1%) and is otherwise identical. For less critical applications, Yageo's AC0805FR-071ML is a functional match with a higher TCR.
