RC5025F1472CS Equivalent & Substitute Parts

Part Overview

The RC5025F1472CS is a 14.7 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 currently in active production status with 828 pieces available in inventory.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained across the same resistance value, tolerance, package format, and operating temperature range. The primary substitute identified is the ERJ-12SF1472U from Panasonic Electronic Components, which maintains electrical equivalence while offering higher power rating and automotive qualification.

Substitute Part Grouping Explanation

Substitution logic for the RC5025F1472CS is based on strict electrical and mechanical parameter matching:

Primary Substitution Criteria:

• Resistance value: 14.7 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Package format: 2010 (5025 Metric) (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (substitute range must encompass or equal this range)
• Composition: Thick Film (exact match required)

Secondary Compatibility Factors:

• Power rating: Substitute may equal or exceed 0.667W
• Moisture sensitivity: Substitute must maintain MSL 1 or better
• RoHS compliance: Substitute must maintain ROHS3 Compliant status

The ERJ-12SF1472U from Panasonic meets all primary criteria with identical electrical specifications and package dimensions. The substitute offers 0.75W power rating (exceeding the 0.667W requirement) and includes AEC-Q200 automotive qualification, though it carries a "Not For New Designs" product status designation.

Parameter Comparison

Engineering Selection Recommendations

For Active Production Applications: The RC5025F1472CS is the primary selection for new designs due to its Active product status. This component maintains full manufacturer support, ongoing production, and availability assurance.

For Existing Design Maintenance or Replacement: The ERJ-12SF1472U from Panasonic serves as a functional equivalent for applications requiring component substitution. All electrical parameters, package dimensions, and operating characteristics are compatible. The higher power rating (0.75W vs. 0.667W) provides additional thermal margin without affecting circuit performance.

Compliance Considerations: Both components maintain ROHS3 compliance and MSL 1 moisture sensitivity rating, ensuring compatibility with standard manufacturing and storage protocols. The ERJ-12SF1472U includes AEC-Q200 automotive qualification, making it suitable for automotive applications where the RC5025F1472CS may not be specified.

Product Status Impact: The ERJ-12SF1472U carries a "Not For New Designs" designation from Panasonic. This status indicates the component remains available for existing applications but is not recommended for new product development. Selection of this substitute should be limited to replacement scenarios or legacy system support.

Frequently Asked Questions (FAQ)

Q: Can the ERJ-12SF1472U directly replace the RC5025F1472CS in existing PCB layouts?

A: Yes. Both components share identical package dimensions (2010/5025 Metric), land patterns, and electrical specifications (14.7 kOhms ±1%, ±100ppm/°C, -55°C ~ 155°C). The maximum seated height difference (0.028" vs. 0.026") is within standard PCB assembly tolerances and does not affect placement or functionality.

Q: What is the significance of the "Not For New Designs" status on the ERJ-12SF1472U?

A: This designation indicates that Panasonic is not actively promoting this component for new product development. However, the component remains in production and available for purchase. It is suitable for replacement applications, legacy system support, and existing design maintenance where the RC5025F1472CS may be unavailable.

Q: Does the higher power rating of the ERJ-12SF1472U (0.75W vs. 0.667W) affect circuit behavior?

A: No. Higher power rating indicates greater thermal capability and does not alter electrical performance. The component will operate identically in circuits designed for the RC5025F1472CS. The increased power rating provides additional thermal margin in applications approaching the original component's power dissipation limit.

Q: Are there packaging differences between these components?

A: The RC5025F1472CS is supplied in standard packaging format. The ERJ-12SF1472U is supplied in Tape & Reel (TR) format. Both formats contain identical components; packaging format affects only handling, storage, and automated assembly compatibility.

Q: What compliance certifications apply to both components?

A: Both components are ROHS3 compliant and REACH unaffected. The ERJ-12SF1472U includes additional AEC-Q200 automotive qualification. Both maintain MSL 1 (Unlimited) moisture sensitivity rating, requiring no special storage conditions.

Q: Can the RC5025F1472CS be used in automotive applications?

A: The RC5025F1472CS does not carry AEC-Q200 automotive qualification. For automotive applications requiring this certification, the ERJ-12SF1472U is the appropriate selection.
