RC5025F1402CS Equivalent & Substitute Parts

Part Overview

The RC5025F1402CS is a 14 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-12SF1402U from Panasonic Electronic Components, which shares the same resistance specification and package dimensions while offering enhanced automotive qualification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC5025F1402CS is determined by strict alignment of the following parameters:

Mandatory Matching Parameters:

• Resistance value: 14 kOhms
• Tolerance: ±1%
• Package footprint: 2010 (5025 Metric)
• Operating temperature range: -55°C ~ 155°C minimum
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Number of terminations: 2

Acceptable Variation Parameters:

• Power rating: Substitute may equal or exceed the 0.667W specification
• Manufacturer: Different manufacturers permitted
• Product status: Active or Not For New Designs both acceptable
• Packaging format: Bulk or Tape & Reel both acceptable
• Additional certifications: Automotive qualification (AEC-Q200) adds value without restricting substitution

The ERJ-12SF1402U meets all mandatory parameters and exceeds the power rating specification at 0.75W (3/4W), making it a valid electrical and mechanical substitute.

Engineering Selection Recommendations

RC5025F1402CS Selection Criteria:

• Primary choice for new designs requiring active product status
• Suitable for general industrial and consumer applications
• Moisture resistance feature supports standard environmental conditions
• RoHS3 compliance and REACH unaffected status meet regulatory requirements

ERJ-12SF1402U Selection Criteria:

• Acceptable as substitute where AEC-Q200 automotive qualification is required or beneficial
• Higher power rating (0.75W vs. 0.667W) provides additional thermal margin in applications approaching maximum power dissipation
• Product status "Not For New Designs" indicates this part is in mature/legacy phase; use only when RC5025F1402CS is unavailable
• Identical electrical performance and package footprint ensure direct PCB compatibility
• Tape & Reel packaging format suitable for high-volume automated assembly

Substitution Constraints:

• Height difference of 0.002" (0.04mm) is negligible for standard PCB assembly processes
• Both parts maintain identical operating temperature range and temperature coefficient specifications
• No performance degradation occurs when substituting ERJ-12SF1402U for RC5025F1402CS in existing designs

Frequently Asked Questions (FAQ)

Q: Can ERJ-12SF1402U be used as a direct replacement for RC5025F1402CS on existing PCBs?

A: Yes. Both components share identical resistance (14 kOhms), tolerance (±1%), package footprint (2010/5025 Metric), and operating temperature range (-55°C ~ 155°C). The height difference of 0.002" (0.04mm) is within standard PCB assembly tolerances and does not affect placement or soldering.

Q: What is the significance of the higher power rating on the ERJ-12SF1402U (0.75W vs. 0.667W)?

A: The ERJ-12SF1402U's 0.75W rating exceeds the RC5025F1402CS specification by 0.083W. This provides additional thermal headroom in applications where the resistor operates near maximum power dissipation. Both parts are electrically equivalent; the higher rating does not change circuit behavior.

Q: Why is the ERJ-12SF1402U marked "Not For New Designs"?

A: This product status indicates the part is in mature production phase and may be subject to discontinuation. For new product development, the RC5025F1402CS (Active status) is the preferred choice. The ERJ-12SF1402U remains suitable for sustaining production of existing designs or as an emergency substitute when primary parts are unavailable.

Q: Are there packaging differences between these parts?

A: The RC5025F1402CS is supplied in standard packaging format (not specified as Tape & Reel). The ERJ-12SF1402U is supplied in Tape & Reel (TR) format, which is standard for automated assembly lines. Both formats contain identical components; packaging format selection depends on assembly process requirements.

Q: Do both parts meet the same compliance standards?

A: Yes. Both RC5025F1402CS and ERJ-12SF1402U are RoHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with identical HTSUS code 8533.21.0030. The ERJ-12SF1402U adds AEC-Q200 automotive qualification, which is not present in the RC5025F1402CS specification.

Q: What is the temperature coefficient significance for these resistors?

A: Both parts specify ±100ppm/°C temperature coefficient, meaning resistance value changes by a maximum of 100 parts per million for each degree Celsius change in operating temperature. This specification is identical across both components and ensures predictable performance across the -55°C ~ 155°C operating range.

Q: Can these parts be used interchangeably in automotive applications?

A: The ERJ-12SF1402U carries AEC-Q200 automotive qualification, making it the preferred choice for automotive applications. The RC5025F1402CS does not specify automotive qualification. For non-automotive applications, both parts are functionally equivalent.
