Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RCS2012F5902CS are qualified based on the following criteria:

Electrical Parameters (Must Match):

• Resistance value: 59 kOhms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters (Must Match):

• Package type: 0805 (2012 Metric)
• Number of terminations: 2
• Physical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm)

Compliance Parameters (Must Match):

• RoHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Unaffected status
• ECCN: EAR99

All substitute parts listed meet these criteria and are classified as Active product status. Variations in height-seated measurements and specific feature sets (such as automotive AEC-Q200 certification or anti-sulfur properties) do not disqualify substitution when core electrical and mechanical specifications align.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts are qualified for direct replacement with the RCS2012F5902CS based on matching electrical specifications, mechanical dimensions, and regulatory compliance. Selection among substitute options is determined by application-specific requirements and availability:

CRCW080559K0FKEA (Vishay Dale): This substitute includes Automotive AEC-Q200 certification, suitable for applications requiring automotive-grade reliability. The seated height of 0.020" (0.50mm) is the lowest among all options, beneficial for space-constrained PCB layouts.

ERJ-6ENF5902V (Panasonic Electronic Components): This substitute includes Automotive AEC-Q200 certification and offers the highest inventory availability (117,734 pcs). The seated height of 0.028" (0.70mm) is the maximum among all options.

RC0805FR-0759KL (YAGEO): This substitute features moisture-resistant properties aligned with the original component. The seated height of 0.024" (0.60mm) provides a mid-range profile. Inventory availability is 46,962 pcs.

All substitute parts maintain ROHS3 compliance, MSL Level 1 (Unlimited), and REACH Unaffected status, ensuring regulatory alignment with the original RCS2012F5902CS component.

Frequently Asked Questions (FAQ)

Q: Can CRCW080559K0FKEA replace RCS2012F5902CS in any application?

A: Yes. Both components share identical electrical specifications (59 kOhms ±1%, 0.125W, ±100ppm/°C), mechanical dimensions (0805 package, 2.00mm x 1.25mm), and compliance certifications (ROHS3, MSL 1, REACH Unaffected). The CRCW080559K0FKEA includes additional Automotive AEC-Q200 certification, which does not restrict its use in non-automotive applications.

Q: What is the significance of the Height - Seated (Max) variation among substitute parts?

A: Height-seated measurements range from 0.020" (0.50mm) to 0.028" (0.70mm) across the substitute options. This variation affects PCB clearance and component placement in high-density layouts. Selection should account for specific PCB design constraints and available vertical space above the component mounting surface.

Q: Are all substitute parts available in Tape & Reel (TR) packaging?

A: Yes. All listed substitute parts, including CRCW080559K0FKEA, ERJ-6ENF5902V, and RC0805FR-0759KL, are supplied in Tape & Reel (TR) packaging format, consistent with the original RCS2012F5902CS.

Q: Does the Automotive AEC-Q200 certification on substitute parts affect their use in consumer applications?

A: No. Automotive AEC-Q200 certification indicates enhanced reliability and quality standards. Components with this certification are fully compatible with consumer and industrial applications and do not impose restrictions on their use outside automotive environments.

Q: What is the difference between anti-sulfur and moisture-resistant features?

A: Anti-sulfur protection prevents corrosion from sulfur-containing atmospheric contaminants, while moisture-resistant properties protect against humidity-induced degradation. The RCS2012F5902CS includes both anti-sulfur and moisture-resistant features. The RC0805FR-0759KL substitute specifies moisture-resistant properties. Both feature sets are compatible with the same operating environment and application requirements.

Q: Can substitute parts be mixed within a single PCB assembly?

A: Yes. All substitute parts meet identical electrical and mechanical specifications, allowing mixed usage within the same assembly. However, for manufacturing consistency and traceability, single-source component selection is recommended.

Q: What inventory levels are available for each substitute part?

A: RCS2012F5902CS (Samsung): 1,111 pcs; CRCW080559K0FKEA (Vishay Dale): 34,023 pcs; ERJ-6ENF5902V (Panasonic): 117,734 pcs; RC0805FR-0759KL (YAGEO): 46,962 pcs. Inventory levels influence lead time and supply chain planning decisions.
