RC5025F68R1CS Equivalent & Substitute Parts Reference

Part Overview

The RC5025F68R1CS is a 68.1 Ohm ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics in the 2010 (5025 Metric) package format. This component delivers 0.667W (2/3W) power dissipation with moisture-resistant construction and operates across the -55°C to 155°C temperature range. The part maintains Active product status with 1013 units currently in stock. Equivalent and substitute parts are identified to support procurement flexibility, design redundancy, and supply chain continuity when the primary part becomes unavailable or when design specifications permit higher power ratings or automotive-grade certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC5025F68R1CS is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 68.1 Ohms
• Tolerance: ±1%
• Package format: 2010 (5025 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• Moisture Sensitivity Level: 1 (Unlimited)
• RoHS Compliance: ROHS3 Compliant

Allowable Variation:

• Power Rating: Substitute parts may exceed the 0.667W specification, provided the higher rating does not introduce incompatibility with the circuit design. The identified substitutes operate at 0.75W (3/4W), which represents a 12.5% increase in power dissipation capability.

Identified Substitutes:

1. CRCW201068R1FKEF (Vishay Dale) – 0.75W, Automotive AEC-Q200 rated
2. RMCF2010FT68R1 (Stackpole Electronics Inc) – 0.75W, Automotive AEC-Q200 rated

Both substitutes maintain identical resistance, tolerance, package dimensions, temperature characteristics, and compliance certifications while providing enhanced power handling capacity and automotive-grade qualification.

Parameter Comparison

Engineering Selection Recommendations

RC5025F68R1CS (Samsung Electro-Mechanics) – Primary Selection

Select this part when the original design specification explicitly requires the 0.667W power rating and moisture-resistant thick film construction without automotive qualification. The component is Active status with established supply (1013 units in stock). Suitable for consumer and industrial applications within the specified temperature and environmental parameters.

CRCW201068R1FKEF (Vishay Dale) – Substitute with Enhanced Capability

This substitute provides identical electrical and mechanical compatibility with the addition of AEC-Q200 automotive qualification and increased 0.75W power rating. Select when design margins permit higher power dissipation or when automotive-grade reliability is required. Packaging is Tape & Reel format with 29200 units in stock, supporting high-volume procurement.

RMCF2010FT68R1 (Stackpole Electronics Inc) – Substitute with Enhanced Capability

This substitute delivers the same electrical performance as CRCW201068R1FKEF with AEC-Q200 automotive qualification and 0.75W power rating. Select when Stackpole supply chain preference is established or when design redundancy across multiple manufacturers is required. Packaging is Tape & Reel format with 8996 units in stock.

Compliance Verification:

All three parts maintain ROHS3 compliance, REACH Unaffected status, and EAR99 export classification. Height variation between the primary part (0.66mm seated) and substitutes (0.70mm seated) is 0.04mm and does not introduce PCB layout incompatibility for standard 2010 package footprints.

Frequently Asked Questions (FAQ)

Q1: Can CRCW201068R1FKEF or RMCF2010FT68R1 be used as direct drop-in replacements for RC5025F68R1CS?

A: Yes, both substitutes are direct drop-in replacements. All three parts share identical resistance (68.1 Ohms), tolerance (±1%), package format (2010/5025 Metric), composition (thick film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C). The 0.04mm height difference (0.66mm vs 0.70mm seated) does not affect PCB assembly compatibility for standard 2010 footprints.

Q2: What is the significance of the higher power rating (0.75W) in the substitute parts?

A: The substitute parts are rated for 0.75W compared to the primary part's 0.667W. This 12.5% increase in power dissipation capability provides additional thermal margin in the circuit. If the design application requires only 0.667W or less, both substitutes operate safely within specification. The higher rating does not degrade performance at lower power levels.

Q3: What does AEC-Q200 automotive qualification mean for the substitute parts?

A: AEC-Q200 is an automotive industry standard qualification that certifies the component for use in automotive applications. Both CRCW201068R1FKEF and RMCF2010FT68R1 carry this certification, making them suitable for automotive-grade designs. The primary RC5025F68R1CS does not carry this specification but remains suitable for non-automotive applications.

Q4: Are there any environmental or compliance differences between the three parts?

A: All three parts are ROHS3 compliant, REACH Unaffected, and classified as EAR99 for export purposes. Moisture Sensitivity Level is 1 (Unlimited) for all parts, indicating no moisture sensitivity restrictions. No environmental or compliance barriers exist to substitution.

Q5: Which substitute should be selected for new design implementations?

A: For new designs, either CRCW201068R1FKEF or RMCF2010FT68R1 is recommended. Both provide enhanced power rating and automotive qualification while maintaining full compatibility with the RC5025F68R1CS electrical and mechanical specifications. Selection between the two substitutes depends on established supplier relationships and inventory availability.

Q6: What is the impact of the 0.04mm height difference on PCB assembly?

A: The height difference (0.66mm primary vs 0.70mm substitutes) is negligible for standard PCB assembly processes. Both dimensions fall within the tolerance band for 2010 package footprints and do not require PCB layout modifications or reflow profile adjustments.

Q7: Can these parts be used interchangeably in existing production runs?

A: Yes, provided the circuit design does not explicitly require the 0.667W specification as a limiting factor. The substitutes' higher power rating and automotive qualification do not introduce incompatibility. Verify with design engineering that the 0.04mm height variation does not conflict with specific assembly constraints or clearance requirements.
