Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC2012F1743CS is determined by strict equivalence across the following parameters:

Electrical Equivalence Requirements:

• Resistance value: 174 kOhms (exact match)
• Tolerance: ±1% (exact match)
• Power rating: 0.125W / 1/8W (exact match)
• Temperature coefficient: ±100ppm/°C (exact match)
• Operating temperature range: -55°C ~ 155°C (exact match)

Mechanical Equivalence Requirements:

• Package format: 0805 (2012 Metric) (exact match)
• Composition: Thick Film (exact match)
• Number of terminations: 2 (exact match)

Compliance Requirements:

• RoHS3 Compliant (mandatory)
• REACH Unaffected (mandatory)
• Moisture Sensitivity Level 1 (mandatory)

All identified substitute parts meet these criteria. Additional features such as Automotive AEC-Q200 certification or moisture-resistant construction represent enhanced specifications that do not prevent substitution but indicate expanded application scope.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts—RC0805FR-07174KL (YAGEO), CRCW0805174KFKEA (Vishay Dale), ERJ-6ENF1743V (Panasonic), and RMCF0805FT174K (Stackpole)—satisfy the complete electrical and mechanical equivalence criteria for direct substitution with the RC2012F1743CS.

Compliance Status: All substitute parts maintain ROHS3 compliance and REACH Unaffected status, matching the original component's regulatory requirements.

Product Availability: Substitute parts demonstrate robust inventory levels: YAGEO RC0805FR-07174KL (28,123 units), Vishay Dale CRCW0805174KFKEA (47,094 units), Panasonic ERJ-6ENF1743V (44,784 units), and Stackpole RMCF0805FT174K (80,642 units).

Automotive Qualification: Three substitute parts—CRCW0805174KFKEA, ERJ-6ENF1743V, and RMCF0805FT174K—carry Automotive AEC-Q200 certification, indicating qualification for automotive-grade applications. This certification does not restrict use in non-automotive applications.

Packaging Consideration: The YAGEO RC0805FR-07174KL is supplied in Cut Tape (CT) & Digi-Reel® format, while the original and remaining substitutes use standard Tape & Reel (TR) packaging. Packaging format selection depends on assembly equipment compatibility and procurement workflow requirements.

Height Variation: Seated height specifications range from 0.020" (0.50mm) to 0.028" (0.70mm). All values remain within typical PCB design clearance tolerances for 0805 components. Height variation does not affect electrical performance or mechanical fit in standard 0805 footprints.

Frequently Asked Questions (FAQ)

Q: Can RC0805FR-07174KL (YAGEO) replace RC2012F1743CS (Samsung) in production?

A: Yes. RC0805FR-07174KL meets all electrical specifications (174 kOhms, ±1%, 0.125W), mechanical requirements (0805 package, 2.00mm x 1.25mm), and compliance standards (ROHS3, REACH Unaffected, MSL 1). The component is electrically and mechanically equivalent for direct substitution.

Q: What is the difference between the substitute parts?

A: All substitute parts share identical electrical and mechanical specifications. Differences exist only in manufacturer identity, packaging format (YAGEO uses Cut Tape & Digi-Reel®; others use Tape & Reel), seated height (ranging 0.020" to 0.028"), and automotive certification status (three parts carry AEC-Q200; Samsung original does not). These differences do not affect substitution eligibility.

Q: Does Automotive AEC-Q200 certification restrict use to automotive applications?

A: No. AEC-Q200 certification indicates the component meets automotive-grade reliability standards. Parts with this certification are suitable for both automotive and non-automotive applications. The certification represents an enhanced qualification level, not a usage restriction.

Q: Are there packaging format compatibility concerns?

A: Packaging format (Tape & Reel vs. Cut Tape & Digi-Reel®) affects procurement and assembly equipment compatibility, not electrical or mechanical performance. Verify that your assembly equipment supports the selected packaging format before procurement.

Q: Does the height variation (0.020" to 0.028") affect PCB design?

A: No. All seated height values fall within standard design clearance tolerances for 0805 (2012 Metric) components. Height variation does not require PCB footprint modification or design changes.

Q: Are all substitute parts currently in stock?

A: Yes. All substitute parts maintain Active product status with confirmed inventory: YAGEO (28,123 units), Vishay Dale (47,094 units), Panasonic (44,784 units), and Stackpole (80,642 units).

Q: Can I mix manufacturers in the same production run?

A: Yes. All substitute parts meet identical electrical and mechanical specifications. Mixed-manufacturer procurement is technically valid. Verify internal procurement and quality assurance policies regarding multi-source component usage.
