RC5025F1963CS Equivalent & Substitute Parts

Part Overview

The RC5025F1963CS is a 196 kOhms ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics, rated for 0.667W (2/3W) power dissipation in a 2010 (5025 Metric) surface mount package. This component is classified as Active product status and is RoHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained across the same resistance value, tolerance, package footprint, and operating temperature range. The primary substitute identified is the ERJ-12SF1963U from Panasonic Electronic Components, which maintains critical electrical parameters while offering higher power rating and automotive qualification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC5025F1963CS is determined by strict adherence to the following electrical and mechanical parameters:

Critical Matching Parameters:

• Resistance value: 196 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Package footprint: 2010 (5025 Metric) (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C to 155°C (minimum required)
• Composition: Thick Film (exact match required)

Allowable Variation Parameters:

• Power rating: Equal to or greater than 0.667W
• Packaging format: May differ (bulk, tape & reel, etc.)
• Manufacturer: Different manufacturers acceptable
• Product status: May vary (Active or Not For New Designs)
• Additional certifications: May be present (e.g., AEC-Q200)

The ERJ-12SF1963U meets all critical matching parameters and exceeds the power rating requirement at 0.75W, making it a valid electrical and mechanical substitute.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: ERJ-12SF1963U (Panasonic Electronic Components)

The ERJ-12SF1963U is electrically and mechanically compatible with the RC5025F1963CS. All critical parameters match exactly: resistance value, tolerance, package footprint, temperature coefficient, and operating temperature range. The substitute provides a higher power rating (0.75W versus 0.667W), which is advantageous for thermal margin in circuit applications.

Compliance Considerations:

Both parts are RoHS3 compliant and REACH unaffected, meeting environmental regulatory requirements. The ERJ-12SF1963U carries AEC-Q200 automotive qualification, which is an additional certification not present in the RC5025F1963CS. This qualification is beneficial for applications requiring automotive-grade reliability but does not restrict use in non-automotive applications.

Product Status Note:

The RC5025F1963CS maintains Active product status, indicating continued manufacturer support and availability. The ERJ-12SF1963U is marked as Not For New Designs, indicating Panasonic has transitioned this part to mature status. For new design implementations, the RC5025F1963CS is the preferred choice. For replacement or repair of existing assemblies, the ERJ-12SF1963U remains functionally equivalent and available in inventory.

Packaging Consideration:

The RC5025F1963CS is supplied in bulk packaging, while the ERJ-12SF1963U is supplied in Tape & Reel format. This difference affects handling and assembly processes but does not impact electrical or mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can the ERJ-12SF1963U be used as a direct replacement for the RC5025F1963CS in existing circuit designs?

A: Yes. The ERJ-12SF1963U is electrically and mechanically compatible. Both parts have identical resistance (196 kOhms), tolerance (±1%), package footprint (2010/5025 Metric), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). The higher power rating of the ERJ-12SF1963U (0.75W versus 0.667W) provides additional thermal margin.

Q: What is the significance of the "Not For New Designs" status on the ERJ-12SF1963U?

A: This designation indicates that Panasonic has classified the ERJ-12SF1963U as a mature product and is not actively promoting it for new circuit designs. However, the part remains functionally equivalent and available for replacement applications. For new designs, the RC5025F1963CS (Active status) is the recommended choice.

Q: Are there any differences in moisture sensitivity between these parts?

A: No. Both the RC5025F1963CS and ERJ-12SF1963U have identical Moisture Sensitivity Level (MSL 1 - Unlimited), indicating no moisture-related handling restrictions during storage or assembly.

Q: Does the AEC-Q200 certification on the ERJ-12SF1963U affect its use in non-automotive applications?

A: No. AEC-Q200 is an automotive qualification standard that establishes reliability requirements. Parts meeting this standard exceed general industrial requirements and are fully compatible with non-automotive applications. The certification does not restrict use outside automotive environments.

Q: What is the impact of different packaging formats (bulk versus Tape & Reel)?

A: Packaging format affects material handling, storage, and assembly processes but does not impact electrical or mechanical performance. Bulk packaging is suitable for manual assembly or small-volume production. Tape & Reel format is optimized for automated pick-and-place assembly. Both formats contain identical components.

Q: Can these parts be used interchangeably in high-precision analog circuits?

A: Yes, within the specified tolerance. Both parts have ±1% tolerance and ±100ppm/°C temperature coefficient. In applications requiring tighter tolerance control, additional screening or selection may be necessary, but this requirement applies equally to both parts and is independent of substitution.

Q: What is the maximum operating temperature for both parts?

A: Both the RC5025F1963CS and ERJ-12SF1963U are rated for continuous operation from -55°C to 155°C. This identical temperature range ensures equivalent performance across the full operating envelope.
