Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC1005F8872CS are classified based on strict equivalence of critical electrical and mechanical parameters. The substitution logic is determined by the following criteria:

Direct Equivalents maintain identical specifications across all key parameters: 88.7 kOhms resistance, ±1% tolerance, 0.063W power rating, 0402 package, ±100ppm/°C temperature coefficient, -55°C to 155°C operating range, and ROHS3 compliance.

Upgrade Parts exceed the original specifications in power rating (0.1W vs. 0.063W) while maintaining all other electrical parameters and package dimensions. These parts provide enhanced thermal performance and are suitable for applications requiring additional power dissipation margin.

Similar Parts match all electrical and mechanical specifications but may include additional certifications (AEC-Q200 automotive qualification) or differ in seated height by ±0.001" to ±0.003". These variations remain within acceptable tolerances for standard PCB assembly processes.

All substitute parts maintain the same 0402 (1005 Metric) package footprint, two-terminal configuration, thick film composition, and ROHS3/REACH compliance status as the original component.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitution (CR0402-FX-8872GLF, RC0402FR-0788K7L): These parts provide complete electrical and mechanical equivalence to the RC1005F8872CS. Both maintain identical resistance, tolerance, power rating, and operating parameters. RC0402FR-0788K7L includes moisture resistant construction matching the original specification. Both parts carry Active product status and ROHS3 compliance. Selection between these options depends on supply chain availability and preferred manufacturer qualification.

Upgrade Selection (ERJ-2RKF8872X): This Panasonic part increases power rating from 0.063W to 0.1W while maintaining all other electrical specifications. The upgrade provides enhanced thermal margin for applications operating near maximum power dissipation limits. AEC-Q200 automotive qualification is included. This part is suitable for designs requiring improved reliability or thermal performance without circuit redesign.

Automotive-Qualified Alternatives (AC0402FR-0788K7L, CRCW040288K7FKED, RMCF0402FT88K7): These parts maintain full electrical equivalence to the original component while adding AEC-Q200 automotive qualification. AC0402FR-0788K7L includes moisture resistant construction. All three parts are suitable for applications requiring automotive-grade component qualification. Selection depends on preferred manufacturer and supply availability.

All substitute parts maintain ROHS3 compliance, unlimited moisture sensitivity level (MSL 1), and identical package footprint for direct PCB assembly compatibility.

Frequently Asked Questions (FAQ)

Q: Can CR0402-FX-8872GLF replace RC1005F8872CS in all applications?

A: Yes. CR0402-FX-8872GLF provides complete electrical and mechanical equivalence. Both parts share identical resistance (88.7 kOhms), tolerance (±1%), power rating (0.063W), package (0402), temperature coefficient (±100ppm/°C), and operating range (-55°C to 155°C). The only difference is the absence of explicit moisture resistant designation in the Bourns part, though both maintain MSL 1 rating.

Q: What is the difference between the 0.063W and 0.1W power-rated parts?

A: ERJ-2RKF8872X is rated at 0.1W (1/10W) compared to the original 0.063W (1/16W) rating. This upgrade provides higher power dissipation capability and improved thermal performance. The 0.1W rating allows the resistor to handle higher current loads without exceeding temperature limits. All other electrical parameters remain identical. This part is suitable for applications requiring additional thermal margin.

Q: Are automotive-qualified parts (AEC-Q200) compatible with non-automotive applications?

A: Yes. AEC-Q200 qualification represents an additional quality and reliability standard. Parts meeting AEC-Q200 (AC0402FR-0788K7L, CRCW040288K7FKED, RMCF0402FT88K7) are fully compatible with non-automotive applications. These parts exceed the original specification and provide enhanced reliability for any application.

Q: Does package footprint differ between substitute parts?

A: No. All substitute parts use the 0402 (1005 Metric) package with identical footprint dimensions (0.039" L x 0.020" W / 1.00mm x 0.50mm). Seated height varies slightly: most parts specify 0.016" (0.40mm) maximum, while AC0402FR-0788K7L specifies 0.015" (0.37mm) maximum. These variations are within standard PCB assembly tolerances and do not affect placement or soldering.

Q: What is the significance of moisture resistant construction?

A: Moisture resistant thick film construction provides enhanced protection against humidity and environmental moisture exposure. RC1005F8872CS and RC0402FR-0788K7L include this feature. AC0402FR-0788K7L also includes moisture resistant construction. This feature is beneficial for applications exposed to high humidity or condensation environments. Parts without explicit moisture resistant designation (CR0402-FX-8872GLF, ERJ-2RKF8872X, CRCW040288K7FKED, RMCF0402FT88K7) maintain MSL 1 rating and are suitable for standard storage and assembly conditions.

Q: Are all substitute parts in Active product status?

A: Yes. All listed substitute parts maintain Active product status, indicating current manufacturing and availability. This ensures long-term supply continuity and support from manufacturers.
