Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1608F8251CS is determined by strict equivalence across the following critical parameters:

Electrical Specifications: Resistance value (8.25 kOhms), tolerance (±1%), and power rating (0.1W) must be identical. Temperature coefficient (±100ppm/°C) and operating temperature range (-55°C ~ 155°C) establish thermal performance boundaries.

Mechanical Compatibility: Package designation (0603 / 1608 Metric), physical dimensions (0.063" L x 0.031" W / 1.60mm x 0.80mm), and seated height (0.022" / 0.55mm maximum) ensure PCB footprint compatibility and assembly process alignment.

Environmental & Compliance Requirements: Moisture Sensitivity Level 1 (Unlimited), RoHS3 compliance, and REACH unaffected status define regulatory and environmental acceptability. Composition (thick film) and moisture-resistant features establish material consistency.

Packaging Format: Cut Tape (CT) and Tape & Reel (TR) formats are interchangeable for component procurement and assembly operations.

Substitute parts are classified as Direct Manufacturer equivalents (identical specifications and features) or Similar alternatives (identical core specifications with additional certifications such as Automotive AEC-Q200 or Anti-Sulfur properties).

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (Identical Specifications & Compliance):

CR0603-FX-8251ELF (Bourns Inc.) and RC0603FR-078K25L (YAGEO) are direct functional equivalents to RC1608F8251CS. Both maintain identical electrical parameters, thermal characteristics, moisture sensitivity level, and RoHS3 compliance status. These parts are suitable for direct substitution in applications where standard industrial-grade thick film resistors are specified.

Automotive-Qualified Alternatives (AEC-Q200 Certified):

AC0603FR-078K25L, AF0603FR-078K25L (YAGEO), CRCW06038K25FKEA (Vishay Dale), ERJ-3EKF8251V (Panasonic), and RMCF0603FT8K25 (Stackpole Electronics Inc) are qualified to Automotive AEC-Q200 standard. These parts maintain all core electrical and mechanical specifications while providing enhanced reliability documentation and qualification testing. AF0603FR-078K25L includes additional anti-sulfur protection. These alternatives are applicable for automotive and high-reliability applications requiring AEC-Q200 certification.

Compliance Consideration:

CRCW06038K25FKTA (Vishay Dale, Tape & Reel format) is RoHS non-compliant and REACH affected. This part is not suitable for applications requiring RoHS3 compliance or REACH compliance verification.

Packaging Format Selection:

Cut Tape (CT) format: RC1608F8251CS (Samsung), RC0603FR-078K25L (YAGEO), CRCW06038K25FKEA (Vishay Dale)

Tape & Reel (TR) format: CR0603-FX-8251ELF (Bourns), AC0603FR-078K25L (YAGEO), AF0603FR-078K25L (YAGEO), CRCW06038K25FKTA (Vishay Dale), ERJ-3EKF8251V (Panasonic), RMCF0603FT8K25 (Stackpole)

Frequently Asked Questions (FAQ)

Q: Can I substitute RC1608F8251CS with CR0603-FX-8251ELF?

A: Yes. CR0603-FX-8251ELF is a direct equivalent manufactured by Bourns Inc. Both parts share identical resistance (8.25 kOhms), tolerance (±1%), power rating (0.1W), package (0603), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), MSL rating (1), and RoHS3 compliance. The primary difference is packaging format (Tape & Reel vs. Cut Tape) and manufacturer. Electrical and mechanical compatibility is confirmed.

Q: What is the difference between standard and AEC-Q200 qualified versions?

A: AEC-Q200 qualification indicates the component has undergone automotive-grade reliability testing and qualification procedures. Parts such as AC0603FR-078K25L, ERJ-3EKF8251V, and RMCF0603FT8K25 carry AEC-Q200 certification. All other electrical and mechanical parameters remain identical to the base RC1608F8251CS specification. AEC-Q200 versions are required for automotive applications; standard versions are suitable for industrial and consumer applications.

Q: Is AF0603FR-078K25L different from AC0603FR-078K25L?

A: Both are YAGEO products with identical core specifications (8.25 kOhms, ±1%, 0.1W, 0603 package, AEC-Q200). The distinction is that AF0603FR-078K25L includes anti-sulfur protection feature, providing enhanced resistance to sulfur-containing environments. AC0603FR-078K25L does not include this feature. Selection depends on application environment requirements.

Q: Can I use CRCW06038K25FKTA as a substitute?

A: CRCW06038K25FKTA maintains identical electrical and mechanical specifications but is RoHS non-compliant and REACH affected. This part is not suitable for applications requiring RoHS3 compliance or REACH compliance verification. Use only if your application explicitly permits non-RoHS components. For RoHS3 compliant applications, select CRCW06038K25FKEA instead.

Q: What are the physical dimension differences between substitute parts?

A: Most substitute parts maintain the standard 0603 package dimensions (0.063" L x 0.031" W / 1.60mm x 0.80mm) with 0.022" (0.55mm) maximum seated height. CRCW06038K25FKEA and CRCW06038K25FKTA (Vishay Dale) have slightly different dimensions: 0.061" L x 0.033" W (1.55mm x 0.85mm) length and width, with 0.020" (0.50mm) maximum seated height. These minor variations remain within 0603 package tolerance and are PCB footprint compatible. RMCF0603FT8K25 (Stackpole) dimensions are 0.061" L x 0.031" W (1.55mm x 0.80mm). Verify PCB layout clearances if tight spacing is critical.

Q: Which substitute has the highest inventory availability?

A: ERJ-3EKF8251V (Panasonic Electronic Components) has 131,634 pieces in stock, representing the highest inventory level among all listed substitutes. RMCF0603FT8K25 (Stackpole Electronics Inc) has 89,349 pieces. CR0603-FX-8251ELF (Bourns Inc.) has 44,560 pieces. These inventory levels support high-volume procurement requirements.

Q: Are all substitute parts suitable for the full -55°C ~ 155°C operating temperature range?

A: Yes. All listed substitute parts maintain the identical operating temperature range of -55°C ~ 155°C and temperature coefficient of ±100ppm/°C. Thermal performance is equivalent across all alternatives.
