Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC1005F8452CS are classified based on strict electrical and mechanical parameter matching. The primary substitution criteria are: resistance value (84.5 kOhms), 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).

Direct Substitutes maintain identical electrical specifications and power rating (0.063W / 1/16W). These parts are interchangeable in applications where the original specification is required.

Upgrade Substitutes provide enhanced power rating (0.1W / 1/10W) or additional certifications (AEC-Q200 automotive qualification) while maintaining all other core electrical parameters. These parts exceed the original specification and are suitable for applications requiring higher reliability or automotive-grade components.

Similar Substitutes match all critical electrical parameters but may include additional features such as automotive AEC-Q200 qualification or enhanced moisture resistance. These parts are compatible with the original application requirements and offer alternative sourcing options.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain full compatibility with the RC1005F8452CS in terms of electrical performance, package format, and environmental specifications. Selection among these alternatives should be based on the following criteria:

For Direct Replacement: CR0402-FX-8452GLF (Bourns Inc.) and RC0402FR-0784K5L (YAGEO) provide identical electrical and mechanical specifications with no additional features or certifications. These parts are suitable for standard commercial applications.

For Moisture-Sensitive Applications: RC0402FR-0784K5L (YAGEO) and AC0402FR-0784K5L (YAGEO) include moisture resistant construction matching or exceeding the original part specification.

For Automotive Applications: ERJ-2RKF8452X (Panasonic), AC0402FR-0784K5L (YAGEO), CRCW040284K5FKED (Vishay Dale), and RMCF0402FT84K5 (Stackpole Electronics Inc) carry AEC-Q200 automotive qualification. ERJ-2RKF8452X provides upgraded 0.1W power rating for enhanced thermal margin in automotive environments.

For High-Reliability Applications: All substitute parts maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with lead-free assembly processes and unlimited shelf life storage conditions.

Frequently Asked Questions (FAQ)

Q: Can CR0402-FX-8452GLF be used as a direct replacement for RC1005F8452CS?

A: Yes. CR0402-FX-8452GLF matches all critical electrical parameters: 84.5 kOhms resistance, ±1% tolerance, 0.063W power rating, 0402 package, ±100ppm/°C temperature coefficient, and -55°C to 155°C operating range. Both parts are ROHS3 compliant with MSL 1 rating.

Q: What is the difference between the main part and ERJ-2RKF8452X?

A: ERJ-2RKF8452X provides a higher power rating of 0.1W (1/10W) compared to the 0.063W (1/16W) of RC1005F8452CS. All other electrical specifications remain identical. The upgrade in power rating provides additional thermal margin and is suitable for applications requiring enhanced reliability or automotive qualification (AEC-Q200).

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

A: Yes. Automotive-qualified parts such as AC0402FR-0784K5L, CRCW040284K5FKED, and RMCF0402FT84K5 meet or exceed the electrical and environmental specifications of the original part and are fully compatible with non-automotive applications. The additional qualification represents enhanced quality and reliability margins.

Q: Does the 0402 package dimension remain consistent across all substitute parts?

A: Yes. All substitute parts use the 0402 (1005 Metric) package format with identical footprint dimensions: 0.039" L x 0.020" W (1.00mm x 0.50mm). Maximum seated height is 0.016" (0.40mm) for all parts except AC0402FR-0784K5L, which has a maximum seated height of 0.015" (0.37mm). This minor variation does not affect PCB layout compatibility.

Q: What is the significance of MSL 1 rating for all parts?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life storage without moisture bake-out requirements. All listed parts, including the main part RC1005F8452CS, carry this rating, ensuring consistent handling and storage procedures across all alternatives.

Q: Can RC0402FR-0784K5L be substituted in applications requiring moisture resistance?

A: Yes. RC0402FR-0784K5L includes moisture resistant construction and is suitable for applications where environmental protection is required. AC0402FR-0784K5L provides both moisture resistance and automotive AEC-Q200 qualification for enhanced environmental performance.
