RC5025F7872CS Equivalent & Substitute Parts

Part Overview

The RC5025F7872CS is a 78.7 kOhms ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics, rated at 0.667W (2/3W) in a 2010 (5025 Metric) surface mount package. This component is classified as Active product status and is currently in stock with 696 pieces available.

The RC5025F7872CS is designed for applications requiring precision resistive elements with moisture resistance and stable performance across industrial temperature ranges. Substitute parts become necessary when original inventory is depleted, when alternative suppliers offer improved lead times, or when design requirements permit higher power ratings or automotive-grade certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC5025F7872CS is determined by strict adherence to the following parameters:

Critical Parameters (Must Match Exactly):

• Resistance Value: 78.7 kOhms
• Tolerance: ±1%
• Package Type: 2010 (5025 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C to 155°C
• Number of Terminations: 2

Allowable Variation Parameters:

• Power Rating: Equal to or greater than 0.667W
• Moisture Sensitivity Level: MSL 1 or better
• RoHS Compliance: ROHS3 or equivalent
• Physical Height: Within manufacturing tolerance

The ERJ-12SF7872U from Panasonic Electronic Components qualifies as a direct substitute because it maintains identical resistance, tolerance, package dimensions, temperature characteristics, and composition specifications. The ERJ-12SF7872U provides a higher power rating (0.75W versus 0.667W), which is acceptable for substitution purposes as it represents an uprated capability within the same package footprint.

Engineering Selection Recommendations

For Active Production and New Designs: The RC5025F7872CS maintains Active product status and is recommended for new designs requiring 78.7 kOhms ±1% thick film resistors in 2010 package format. This component is currently in stock with adequate inventory (696 pieces) and meets all ROHS3 compliance requirements.

For Existing Designs Requiring Substitution: The ERJ-12SF7872U from Panasonic Electronic Components is electrically and mechanically compatible with the RC5025F7872CS. However, the ERJ-12SF7872U carries "Not For New Designs" status, indicating it is suitable only for legacy design support or replacement applications. The ERJ-12SF7872U provides the following advantages: higher power rating (0.75W versus 0.667W), AEC-Q200 automotive qualification, and alternative supplier availability (1144 pieces in stock).

Compliance Considerations: Both components are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with identical HTSUS codes (8533.21.0030). Both components maintain MSL 1 moisture sensitivity rating, indicating unlimited shelf life under standard storage conditions.

Physical Compatibility: The maximum seated height difference (0.70mm for ERJ-12SF7872U versus 0.66mm for RC5025F7872CS) is within standard PCB assembly tolerances and does not restrict substitution in standard surface mount applications.

Frequently Asked Questions (FAQ)

Q: Can the ERJ-12SF7872U replace the RC5025F7872CS in existing circuit designs?

A: Yes. The ERJ-12SF7872U is electrically and mechanically compatible. Both components share identical resistance value (78.7 kOhms), tolerance (±1%), package type (2010/5025 Metric), composition (thick film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). The ERJ-12SF7872U's higher power rating (0.75W versus 0.667W) does not create compatibility issues in circuits designed for the RC5025F7872CS.

Q: What is the significance of the "Not For New Designs" status on the ERJ-12SF7872U?

A: This designation indicates that Panasonic Electronic Components does not recommend the ERJ-12SF7872U for new product development. However, it remains suitable for replacement, repair, and legacy design support. For new designs, the RC5025F7872CS (Active status) is the preferred choice.

Q: Are there dimensional compatibility concerns between these two parts?

A: No. Both components use the identical 2010 (5025 Metric) package with dimensions of 5.00mm length × 2.50mm width. The maximum seated height varies slightly (0.66mm for RC5025F7872CS versus 0.70mm for ERJ-12SF7872U), but this 0.04mm difference is within standard PCB assembly tolerances and does not affect placement or soldering.

Q: Do both components meet automotive qualification requirements?

A: The RC5025F7872CS does not specify automotive qualification. The ERJ-12SF7872U carries AEC-Q200 automotive qualification, making it suitable for automotive applications where this certification is required. For non-automotive applications, both components are equivalent.

Q: What is the moisture sensitivity implication for storage and handling?

A: Both components are rated MSL 1 (Unlimited), indicating they have unlimited shelf life under standard storage conditions (typically 23°C ±2°C, 45% to 75% relative humidity). No special moisture control or baking procedures are required before assembly.

Q: Are there supply chain advantages to using the ERJ-12SF7872U?

A: The ERJ-12SF7872U currently has higher inventory availability (1144 pieces versus 696 pieces for the RC5025F7872CS). However, the RC5025F7872CS maintains Active status, suggesting continued manufacturer support and potentially more stable long-term availability. Supply chain selection should be based on project timeline and inventory requirements.
