Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC5025F1052CS are qualified based on the following criteria:

Electrical Parameters (Must Match):

• Resistance value: 10.5 kOhms
• Tolerance: ±1%
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters (Must Match):

• Package / Case: 2010 (5025 Metric)
• Number of terminations: 2
• Physical dimensions: 0.197" L x 0.098" W (5.00mm x 2.50mm)

Compliance Parameters (Must Match):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Power Rating Consideration: Substitute parts with equal or higher power ratings (0.667W or greater) are acceptable. The RC5025F1052CS operates at 0.667W; substitutes rated at 0.75W or higher maintain thermal margin and circuit reliability.

Parameter Comparison

Engineering Selection Recommendations

AC2010FK-0710K5L (YAGEO) - Upgrade Substitute: This part is qualified as a direct substitute with enhanced specifications. The YAGEO AC2010FK-0710K5L maintains all electrical and mechanical compatibility with the RC5025F1052CS while providing increased power rating (0.75W versus 0.667W) and automotive AEC-Q200 qualification. Product status is Active, supporting long-term availability and new design implementation. This part is suitable for applications requiring automotive-grade reliability or where higher thermal margin is beneficial.

ERJ-12SF1052U (Panasonic) - Similar Substitute: This part meets all electrical and mechanical substitution criteria with equivalent 0.75W power rating and automotive AEC-Q200 qualification. However, product status is classified as Not For New Designs, indicating Panasonic has discontinued active development for this component. The ERJ-12SF1052U remains available in current inventory (3344 Pcs) and is suitable for replacement or repair applications in existing designs. New design implementations should prioritize the AC2010FK-0710K5L or RC5025F1052CS.

Frequently Asked Questions (FAQ)

Q: Can AC2010FK-0710K5L replace RC5025F1052CS in existing designs? A: Yes. The AC2010FK-0710K5L is electrically and mechanically compatible. Both parts share identical resistance (10.5 kOhms), tolerance (±1%), temperature coefficient (±100ppm/°C), operating range (-55°C ~ 155°C), and 2010 package footprint. The higher power rating (0.75W) of the YAGEO part provides additional thermal margin.

Q: What is the difference between the two substitute parts? A: Both AC2010FK-0710K5L and ERJ-12SF1052U meet substitution criteria. The primary distinction is product status: AC2010FK-0710K5L is Active (recommended for new designs), while ERJ-12SF1052U is Not For New Designs (suitable for replacement only). Both include automotive AEC-Q200 qualification.

Q: Are there height differences that affect PCB assembly? A: Seated height differences are minimal. RC5025F1052CS: 0.66mm, AC2010FK-0710K5L: 0.65mm, ERJ-12SF1052U: 0.70mm. These variations fall within standard PCB assembly tolerances and do not affect placement or soldering processes for the 2010 package format.

Q: Do all substitute parts maintain RoHS3 compliance? A: Yes. RC5025F1052CS, AC2010FK-0710K5L, and ERJ-12SF1052U are all ROHS3 Compliant with Moisture Sensitivity Level 1 (Unlimited), ensuring equivalent environmental and regulatory compliance.

Q: Which part should be selected for new product designs? A: For new designs, select either RC5025F1052CS (Samsung, Active status) or AC2010FK-0710K5L (YAGEO, Active status with automotive qualification). Avoid ERJ-12SF1052U for new designs due to Not For New Designs status.
