RC1005F8453CS Equivalent & Substitute Parts Reference

Part Overview

The RC1005F8453CS is a 845 kOhms ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics in 0402 (1005 Metric) package format. This surface mount device is rated at 0.063W (1/16W) power dissipation with moisture resistant construction and operates across the temperature range of -55°C to 155°C. The part maintains Active product status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). Equivalent and substitute parts are identified to support design flexibility, supply chain continuity, and application-specific requirements such as automotive qualification or enhanced power ratings.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1005F8453CS is determined by strict equivalence across the following critical parameters: resistance value (845 kOhms), tolerance (±1%), package format (0402 / 1005 Metric), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and regulatory compliance (ROHS3, REACH Unaffected, EAR99). Power rating, while a key specification, permits substitution with equal or higher rated devices. Automotive AEC-Q200 qualification and moisture resistant features are application-dependent enhancements that do not restrict substitution but may be selected based on end-use requirements. All identified substitutes maintain identical electrical performance and mechanical compatibility with the original part.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain full electrical and mechanical compatibility with the RC1005F8453CS. Selection among equivalent options should be based on the following criteria:

Direct Equivalents (CR0402-FX-8453GLF, RC0402FR-07845KL): These parts provide identical specifications including power rating and package dimensions. CR0402-FX-8453GLF from Bourns Inc. and RC0402FR-07845KL from YAGEO are suitable for applications requiring standard industrial-grade thick film resistors with ROHS3 compliance.

Enhanced Power Rating (ERJ-2RKF8453X): The Panasonic ERJ-2RKF8453X offers 0.1W (1/10W) power rating compared to the 0.063W (1/16W) of the original part. This upgrade provides additional thermal margin and is suitable for applications with higher power dissipation requirements. Automotive AEC-Q200 qualification is included.

Automotive-Qualified Options (CRCW0402845KFKED, RMCF0402FT845K, ERJ-2RKF8453X): These parts carry AEC-Q200 automotive qualification and are appropriate for automotive and high-reliability applications. CRCW0402845KFKED (Vishay Dale) and RMCF0402FT845K (Stackpole Electronics Inc) maintain the 0.063W rating, while ERJ-2RKF8453X provides the enhanced 0.1W rating.

All substitutes are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes.

Frequently Asked Questions (FAQ)

Q: Can CR0402-FX-8453GLF replace RC1005F8453CS in all applications?

A: Yes. CR0402-FX-8453GLF from Bourns Inc. is a direct equivalent with identical resistance (845 kOhms), tolerance (±1%), power rating (0.063W), package (0402), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). Both parts are ROHS3 compliant with MSL 1 rating. The primary difference is the absence of moisture resistant features in the Bourns part; applications requiring moisture resistance should specify RC0402FR-07845KL instead.

Q: What is the difference between the 0.063W and 0.1W power ratings?

A: The RC1005F8453CS and most substitutes are rated at 0.063W (1/16W), while ERJ-2RKF8453X is rated at 0.1W (1/10W). The higher power rating of the Panasonic part provides greater thermal dissipation capability and margin for applications with elevated power requirements. A 0.1W part can be substituted for a 0.063W requirement without electrical or thermal concerns.

Q: Are automotive-qualified parts necessary for non-automotive applications?

A: Automotive AEC-Q200 qualification is not required for standard industrial applications. However, AEC-Q200 parts (CRCW0402845KFKED, RMCF0402FT845K, ERJ-2RKF8453X) undergo additional qualification testing and are suitable for high-reliability and mission-critical applications. Selection should be based on application requirements rather than qualification status alone.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes. All identified substitutes share identical package dimensions (0.039" L x 0.020" W / 1.00mm x 0.50mm), height (0.016" / 0.40mm maximum), and two-terminal configuration. They are mechanically and electrically interchangeable on PCB layouts designed for 0402 (1005 Metric) package format.

Q: What is the significance of moisture resistant construction?

A: Moisture resistant thick film construction (featured in RC1005F8453CS and RC0402FR-07845KL) provides enhanced protection against moisture ingress and is beneficial in high-humidity or condensing environments. Both parts maintain MSL 1 (unlimited) rating. For applications without specific moisture exposure concerns, non-moisture-resistant equivalents are functionally equivalent.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All identified substitute parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and use.
