Part Overview

The RC5025J752CS is a 7.5 kOhms ±5% thick film chip resistor manufactured by Samsung Electro-Mechanics in the 2010 (5025 Metric) package format with a power rating of 0.667W (2/3W). This component is classified as Active product status and features moisture-resistant construction suitable for general industrial applications. The part operates across a temperature range of -55°C to 155°C with a temperature coefficient of ±100ppm/°C.

Equivalent and substitute parts are identified based on matching the core electrical specifications: 7.5 kOhms resistance value, 2010 package dimensions, thick film composition, and compatible operating temperature range. Substitute parts may differ in tolerance grade, power rating, and application-specific certifications while maintaining functional compatibility in circuit designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the RC5025J752CS is based on the following critical parameters that must remain constant or compatible:

Mandatory Matching Parameters:

• Resistance value: 7.5 kOhms (exact match required)
• Package format: 2010 (5025 Metric) (physical and electrical compatibility)
• Composition: Thick film (material consistency)
• Operating temperature range: -55°C ~ 155°C (thermal envelope)
• Temperature coefficient: ±100ppm/°C (thermal stability)
• Number of terminations: 2 (connection compatibility)

Allowable Variation Parameters:

• Tolerance: May be tighter (±1%) than the original ±5% specification
• Power rating: May be equal or higher (0.75W acceptable for 0.667W requirement)
• Features: May include additional certifications (AEC-Q200 automotive qualification)
• Packaging format: May differ (Tape & Reel acceptable for component-level substitution)

The three identified substitute parts (CRCW20107K50FKEF, ERJ-12SF7501U, RMCF2010FT7K50) meet all mandatory parameters while offering improved tolerance grades and automotive-grade certifications.

Parameter Comparison

Engineering Selection Recommendations

CRCW20107K50FKEF (Vishay Dale) is suitable for direct substitution with the following characteristics: Active product status ensures ongoing availability and manufacturing support. The ±1% tolerance provides improved accuracy compared to the original ±5% specification. The 0.75W power rating exceeds the 0.667W requirement, providing additional thermal margin. AEC-Q200 automotive qualification is available for applications requiring automotive-grade components. ROHS3 compliance and MSL 1 rating match the original part specifications.

ERJ-12SF7501U (Panasonic Electronic Components) meets all electrical and mechanical compatibility requirements but carries a "Not For New Designs" product status designation. This status indicates the manufacturer is phasing out this component line. While functionally equivalent with ±1% tolerance and AEC-Q200 certification, new designs should prioritize active-status alternatives. Existing designs currently using this part may continue with this substitute, but long-term availability cannot be assured.

RMCF2010FT7K50 (Stackpole Electronics Inc) is suitable for direct substitution with Active product status. The ±1% tolerance and 0.75W power rating provide equivalent or superior performance characteristics. AEC-Q200 automotive certification is included. ROHS3 compliance and MSL 1 rating are consistent with the original specification. This part offers the combination of active status, improved tolerance, and automotive qualification.

For new designs, CRCW20107K50FKEF or RMCF2010FT7K50 are preferred due to Active product status. For existing designs currently using RC5025J752CS, all three substitutes provide functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can CRCW20107K50FKEF replace RC5025J752CS in existing designs?

A: Yes. Both parts share identical resistance (7.5 kOhms), package format (2010), operating temperature range (-55°C ~ 155°C), and temperature coefficient (±100ppm/°C). The substitute offers tighter tolerance (±1% vs ±5%) and higher power rating (0.75W vs 0.667W), both of which are compatible with the original application. Physical dimensions are equivalent within specified tolerances.

Q: What is the significance of the ±1% tolerance in substitute parts compared to the original ±5%?

A: Tolerance specifies the allowable deviation from the nominal 7.5 kOhms resistance value. The original RC5025J752CS allows resistance between 7.125 kOhms and 7.875 kOhms. Substitute parts with ±1% tolerance restrict the range to 7.425 kOhms to 7.575 kOhms. This tighter tolerance provides improved circuit accuracy and stability. Applications sensitive to resistance variation benefit from the substitute parts' improved tolerance grade.

Q: Why do substitute parts have higher power ratings (0.75W vs 0.667W)?

A: Power rating indicates the maximum power dissipation the resistor can safely handle. A higher power rating (0.75W) provides additional thermal margin compared to the original 0.667W specification. This does not change the component's electrical behavior in the circuit; it only indicates greater thermal capacity. Higher power ratings are compatible with applications designed for lower power ratings.

Q: Are the physical dimensions of substitute parts identical to the original?

A: Substitute parts use the same 2010 (5025 Metric) package format with identical length (0.197" / 5.00mm) and width (0.098" / 2.50mm). Maximum seated height differs slightly: original part 0.026" (0.66mm) versus substitutes 0.028" (0.70mm). This 0.002" (0.04mm) difference is within standard PCB design tolerances and does not affect component placement or circuit functionality.

Q: What does "Not For New Designs" status mean for ERJ-12SF7501U?

A: This designation indicates Panasonic is discontinuing this product line. While the part remains functionally equivalent and currently available in inventory (2036 Pcs), the manufacturer is transitioning customers to alternative products. New circuit designs should select CRCW20107K50FKEF or RMCF2010FT7K50 to ensure long-term component availability and manufacturing support.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The original RC5025J752CS and all three substitute parts (CRCW20107K50FKEF, ERJ-12SF7501U, RMCF2010FT7K50) are ROHS3 compliant. All parts also carry Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements during storage or assembly.

Q: What is AEC-Q200 certification and why do substitute parts include it?

A: AEC-Q200 is an automotive industry qualification standard for passive components. All three substitute parts include this certification, indicating they meet automotive-grade reliability and performance requirements. The original RC5025J752CS does not specify AEC-Q200 certification. For applications requiring automotive-grade components, substitute parts with AEC-Q200 certification provide additional qualification assurance.
