RC5025F1961CS Equivalent & Substitute Parts Reference

Part Overview

The RC5025F1961CS is a 1.96 kOhms ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics in the 2010 (5025 Metric) package format with 0.667W power rating. This component is classified as Active product status and features moisture-resistant construction suitable for general industrial applications. The part is ROHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Substitute parts become necessary when the primary component experiences supply constraints, extended lead times, or when design requirements permit higher power ratings or enhanced automotive qualification. The substitute parts listed maintain electrical equivalence while offering alternative sourcing options and enhanced feature sets.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC5025F1961CS is determined by strict adherence to the following parameters:

Mandatory Equivalence Criteria:

• Resistance value: 1.96 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Package type: 2010 (5025 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature Coefficient: ±100ppm/°C (exact match required)
• Operating Temperature Range: -55°C to 155°C (exact match required)
• Number of Terminations: 2 (exact match required)

Allowable Variation Parameters:

• Power Rating: Minimum 0.667W (substitutes may exceed this value)
• Features: Additional certifications or enhancements permitted (e.g., Automotive AEC-Q200)
• Packaging Format: Tape & Reel acceptable as alternative to standard packaging
• Moisture Sensitivity Level: MSL 1 maintained across all substitutes

The two substitute parts listed below satisfy all mandatory equivalence criteria while offering enhanced power ratings and automotive qualification.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (Active Status): The RC5025F1961CS remains the preferred selection for new designs requiring the specified 0.667W power rating with moisture-resistant construction. This component maintains Active product status with full manufacturer support and availability.

First Substitute Option: The CRCW20101K96FKEF (Vishay Dale) is the recommended substitute when supply constraints affect the primary part. This component maintains Active product status, provides 0.75W power rating capability, and includes Automotive AEC-Q200 qualification. The increased power rating offers thermal margin without affecting electrical performance. Physical dimensions remain compatible with 2010 package specifications.

Secondary Substitute Option: The ERJ-12SF1961U (Panasonic Electronic Components) provides electrical equivalence with 0.75W power rating and Automotive AEC-Q200 qualification. However, this component carries "Not For New Designs" product status, restricting its use to legacy system maintenance, repair, or replacement applications only. This part should not be selected for new product development.

Compliance Considerations: All three components maintain ROHS3 compliance, MSL 1 rating, and identical operating temperature ranges. Height variation between the primary part (0.66mm) and substitutes (0.70mm) remains within typical PCB assembly tolerances and does not affect functional performance.

Frequently Asked Questions (FAQ)

Q: Can CRCW20101K96FKEF replace RC5025F1961CS in existing designs?

A: Yes. The CRCW20101K96FKEF maintains identical electrical specifications (1.96 kOhms ±1%, ±100ppm/°C, -55°C to 155°C operating range) and package dimensions (2010/5025 Metric). The 0.75W power rating exceeds the 0.667W requirement, providing additional thermal margin. Physical height difference (0.70mm vs 0.66mm) is within standard PCB assembly tolerances.

Q: Why is ERJ-12SF1961U marked "Not For New Designs"?

A: The ERJ-12SF1961U carries "Not For New Designs" status from Panasonic, indicating the manufacturer has transitioned this product line. This designation restricts use to replacement and repair of existing systems only. New product development must select components with Active status.

Q: Are all three parts electrically interchangeable?

A: Yes, within the specified operating parameters. All three components provide 1.96 kOhms ±1% resistance, ±100ppm/°C temperature coefficient, and -55°C to 155°C operating range. The power rating difference (0.667W vs 0.75W) does not affect electrical interchangeability; higher ratings provide additional thermal capacity.

Q: What is the significance of Automotive AEC-Q200 qualification on the substitute parts?

A: Automotive AEC-Q200 qualification indicates the component meets automotive industry reliability and quality standards. This certification is not present on the RC5025F1961CS but is available on both substitute options. For non-automotive applications, this qualification provides no functional benefit but indicates enhanced manufacturing process control.

Q: Can I use these parts interchangeably in Tape & Reel packaging?

A: The substitute parts are supplied in Tape & Reel (TR) format, which is standard for automated assembly processes. The RC5025F1961CS packaging format is not specified in the provided data. Tape & Reel format is compatible with standard pick-and-place assembly equipment and does not affect component performance.

Q: What is the maximum height clearance requirement for PCB assembly?

A: The RC5025F1961CS has maximum seated height of 0.66mm, while both substitute parts have maximum seated height of 0.70mm. This 0.04mm difference is negligible for standard PCB assembly and does not typically affect component placement or clearance requirements.

Q: Are all parts ROHS3 compliant?

A: Yes. The RC5025F1961CS, CRCW20101K96FKEF, and ERJ-12SF1961U all maintain ROHS3 compliance status, meeting current environmental and hazardous substance restrictions.
