Substitute Part Grouping Explanation

Substitution of the RC1005F2R0CS is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Resistance value: 2 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.063W minimum (1/16W)
• Composition: Thick Film

Mechanical Equivalence Requirements:

• Package format: 0402 (1005 Metric) with identical footprint dimensions (1.00mm L × 0.50mm W)
• Number of terminations: 2
• Height seated maximum: 0.016" (0.40mm)

Environmental & Compliance Requirements:

• Operating temperature range: -55°C to 155°C minimum
• Moisture Sensitivity Level: 1 (Unlimited) or equivalent
• RoHS Status: ROHS3 Compliant minimum
• REACH Status: REACH Unaffected

The substitute part RMCF0402FT2R00 meets all electrical, mechanical, and environmental criteria. Additional differences in temperature coefficient (±200ppm/°C vs. ±300ppm/°C) and automotive qualification (AEC-Q200) represent enhanced performance characteristics that do not prevent substitution.

Engineering Selection Recommendations

Primary Selection (RC1005F2R0CS): The Samsung Electro-Mechanics RC1005F2R0CS is suitable for applications requiring moisture-resistant thick film construction with standard temperature coefficient performance. Active product status and ROHS3 compliance support long-term availability and regulatory conformance.

Substitute Selection (RMCF0402FT2R00): The Stackpole Electronics RMCF0402FT2R00 provides direct electrical and mechanical equivalence with enhanced temperature stability (±200ppm/°C vs. ±300ppm/°C) and automotive-grade qualification (AEC-Q200). This substitute is appropriate for applications requiring improved temperature coefficient performance or automotive supply chain compliance. Active product status and ROHS3 compliance are maintained.

Selection Criteria:

• Both parts maintain identical electrical specifications (2 Ohms ±1%, 0.063W)
• Both parts are mechanically interchangeable in 0402 footprint applications
• Both parts satisfy environmental operating range (-55°C to 155°C)
• Both parts comply with ROHS3 and REACH requirements
• Substitute part offers superior temperature coefficient stability
• Substitute part includes automotive qualification certification

Frequently Asked Questions (FAQ)
