Substitute Part Grouping Explanation

Substitution eligibility for the RC1005F7870CS is determined by strict equivalence across the following critical parameters: resistance value (787 Ohms), tolerance (±1%), package format (0402 / 1005 Metric), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and compliance certifications (ROHS3, MSL 1).

The substitute parts are categorized as follows:

Direct Equivalent: RC0402FR-07787RL (YAGEO) matches all electrical and mechanical specifications identically to the main part, including 0.063W power rating and moisture resistant features.

Upgrade Category: ERJ-2RKF7870X (Panasonic Electronic Components) provides higher power rating (0.1W / 1/10W) while maintaining all other specifications, offering enhanced thermal performance for applications requiring additional power dissipation margin. This part includes AEC-Q200 automotive qualification.

Similar Category: CRCW0402787RFKED (Vishay Dale) and RMCF0402FT787R (Stackpole Electronics Inc) maintain identical electrical and mechanical specifications to the main part with addition of AEC-Q200 automotive qualification, suitable for applications requiring automotive-grade reliability without power rating changes.

All substitute parts maintain the same 0402 package footprint, enabling direct PCB layout compatibility without redesign.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement: RC0402FR-07787RL (YAGEO) is the primary equivalent substitute, offering identical electrical specifications, power rating, and compliance certifications. This part is suitable for applications where the original Samsung part is unavailable and no additional performance requirements exist.
