What risks should I check before replacing MF2WS-100Ω±1%-6T63?

Before replacing, you must verify the substitute's physical dimensions (body length and diameter) and its taping specification. A mismatch could disrupt automated placement. For lower-spec alternatives, also confirm that a wider tolerance (e.g., ±5%) or different technology (e.g., Carbon Film) is acceptable for your circuit's performance.

MF2WS-100Ω±1%-6T63 Alternatives, Datasheet & Cross Reference | EVVO

The MF2WS-100Ω±1%-6T63 is a 2W, 100 Ohm, 1% tolerance metal film resistor in an axial package. Several strong alternatives are available, including pin-compatible options and power upgrades, requiring only verification of physical dimensions for a successful substitution.

AI replacement insight

Electrical risklow

Several candidates match or exceed the target's key electrical ratings (power, resistance, tolerance).

Package riskmedium

While all are axial, body length/diameter and taping specs can vary between series and manufacturers. This must be verified.

Sourcing risklow

This is a common resistor value with multiple manufacturers available, indicating good sourcing depth.

Can it be replaced directly?

Direct replacement for MF2WS-100Ω±1%-6T63 should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

The CCO part MF2WS-100Ω±1% T is the most promising alternative, matching all key electrical specs. Verification of its physical dimensions against the target is the only required check.

Main risk

The primary risk across all candidates is a mismatch in physical body size or taping specifications (e.g., T&R pitch), which can impact automated manufacturing processes.

Recommended alternatives

A 2W, 100Ω, ±1% metal film resistor from CCO in a similar axial package. A strong potential pin-to-pin replacement.
