Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCS2012F1870CS is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Resistance value: 187 Ohms (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 & Package Equivalence Requirements:

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

Compliance & Environmental Requirements:

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

All four substitute parts listed below meet these equivalence criteria and are therefore direct functional replacements for the RCS2012F1870CS in standard circuit applications.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts are functionally equivalent to the RCS2012F1870CS and meet identical electrical and mechanical specifications. Selection among these alternatives is based on the following factors:

General Purpose Applications: The RC0805FR-07187RL (YAGEO) and RCS2012F1870CS (Samsung) are suitable for standard applications requiring moisture-resistant thick film construction without automotive qualification.

Automotive Applications: The CRCW0805187RFKEA (Vishay Dale), ERJ-6ENF1870V (Panasonic), and RMCF0805FT187R (Stackpole) are qualified to AEC-Q200 automotive standards and are appropriate for automotive circuit designs and high-reliability applications.

Compliance Verification: All parts maintain ROHS3 compliance, MSL Level 1 (Unlimited moisture sensitivity), and REACH Unaffected status, ensuring regulatory compliance across global markets.

Physical Clearance Consideration: Height variations range from 0.020" (0.50mm) to 0.028" (0.70mm). In space-constrained PCB layouts, the CRCW0805187RFKEA offers the lowest profile at 0.020" maximum seated height.

Frequently Asked Questions (FAQ)

Q: Can CRCW0805187RFKEA replace RCS2012F1870CS directly?

A: Yes. The CRCW0805187RFKEA meets all electrical and mechanical equivalence criteria: 187 Ohms ±1%, 0.125W power rating, 0805 package, ±100ppm/°C temperature coefficient, and -55°C ~ 155°C operating range. The primary difference is AEC-Q200 automotive qualification, which provides additional reliability assurance.

Q: What is the difference between the Samsung RCS2012F1870CS and YAGEO RC0805FR-07187RL?

A: Both parts are electrically and mechanically identical with matching resistance, tolerance, power rating, package, and temperature specifications. The RCS2012F1870CS features anti-sulfur construction, while the RC0805FR-07187RL emphasizes moisture resistance. Both are ROHS3 compliant and MSL Level 1.

Q: Are the automotive-qualified parts (Vishay, Panasonic, Stackpole) suitable for non-automotive applications?

A: Yes. AEC-Q200 qualification represents a superset of standard reliability requirements. Automotive-qualified parts can be used in general-purpose applications without restriction.

Q: Does the height difference between substitute parts affect PCB assembly?

A: Height variations (0.020" to 0.028") are within standard 0805 package tolerances and do not affect reflow soldering or standard PCB assembly processes. Selection based on height is only necessary in applications with severe vertical space constraints.

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

A: Yes. All listed substitute parts are supplied in Tape & Reel (TR) format, matching the packaging specification of the RCS2012F1870CS.

Q: Can these parts be used interchangeably in the same circuit board design?

A: Yes. All substitute parts are direct functional equivalents with identical electrical performance, mechanical fit, and environmental compliance. No circuit design modifications are required for substitution.
