Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC5025F8662CS is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance Value: 86.6 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Package / Case: 2010 (5025 Metric) (exact match required)
• Number of Terminations: 2 (exact match required)
• Temperature Coefficient: ±100ppm/°C (exact match required)
• Operating Temperature Range: -55°C ~ 155°C (exact match required)

Allowable Variation Parameters:

• Power Rating: Substitute parts may have equal or higher power ratings (0.667W or greater)
• Composition: Thick Film (maintained across all substitutes)
• Moisture Sensitivity Level: 1 (Unlimited) (maintained across all substitutes)

The identified substitute parts AC2010FK-0786K6L and ERJ-12SF8662U maintain all mandatory electrical and mechanical parameters while providing enhanced power ratings of 0.75W (3/4W), representing a direct upgrade path for applications requiring higher power dissipation capability within the same physical footprint.

Engineering Selection Recommendations

AC2010FK-0786K6L (YAGEO) - Recommended Upgrade Substitute:

The AC2010FK-0786K6L is classified as an upgrade substitute with Active product status. This component maintains full electrical and mechanical compatibility with the RC5025F8662CS while providing a 0.083W (12.5%) increase in power rating from 0.667W to 0.75W. The part is RoHS3 compliant and includes AEC-Q200 automotive qualification, making it suitable for applications requiring enhanced reliability margins or automotive-grade performance. The identical 2010 package footprint and termination configuration ensure direct PCB compatibility without layout modifications.

ERJ-12SF8662U (Panasonic Electronic Components) - Similar Substitute:

The ERJ-12SF8662U is classified as a similar substitute with Not For New Designs product status. While this component matches all electrical specifications and maintains the 2010 package format, it carries RoHS non-compliance status and is designated as not suitable for new design implementations. The AEC-Q200 automotive qualification is present; however, the product lifecycle status and RoHS compliance gap make this option unsuitable for new applications or designs requiring regulatory compliance.

For new designs and applications requiring regulatory compliance, AC2010FK-0786K6L is the appropriate substitute selection. For legacy system maintenance where RoHS compliance is not a requirement, ERJ-12SF8662U remains electrically and mechanically compatible.

Frequently Asked Questions (FAQ)

Q: Can AC2010FK-0786K6L be used as a direct replacement for RC5025F8662CS?

A: Yes. The AC2010FK-0786K6L maintains identical resistance value (86.6 kOhms), tolerance (±1%), package format (2010), and operating temperature range (-55°C ~ 155°C). The higher power rating (0.75W versus 0.667W) represents an upgrade that does not compromise compatibility. PCB footprint and termination configuration are identical, requiring no layout modifications.

Q: What is the difference between the upgrade and similar substitute classifications?

A: AC2010FK-0786K6L is classified as an upgrade substitute because it provides enhanced specifications (higher power rating) while maintaining full compatibility and Active product status with RoHS3 compliance. ERJ-12SF8662U is classified as similar because while it matches electrical specifications, it carries Not For New Designs status and RoHS non-compliance, limiting its application scope.

Q: Are there any height differences between these parts that could affect PCB assembly?

A: Minor height variations exist within acceptable tolerances. RC5025F8662CS has a maximum seated height of 0.026" (0.66mm), AC2010FK-0786K6L is 0.026" (0.65mm), and ERJ-12SF8662U is 0.028" (0.70mm). These differences fall within standard PCB assembly clearance specifications for 2010 package components and do not require design modifications.

Q: Why is ERJ-12SF8662U marked as Not For New Designs?

A: The ERJ-12SF8662U carries Not For New Designs status as assigned by the manufacturer, indicating the product is in end-of-life phase. While electrically and mechanically compatible, this designation reflects manufacturer lifecycle decisions. For new applications, AC2010FK-0786K6L is the appropriate selection.

Q: Does the power rating increase from 0.667W to 0.75W affect circuit performance?

A: No. The higher power rating in AC2010FK-0786K6L indicates increased power dissipation capability, not increased power delivery to the circuit. The resistance value and tolerance remain identical, maintaining the same voltage division and current limiting characteristics. The upgrade provides additional thermal margin for applications operating near the original power specification limits.

Q: What is the significance of AEC-Q200 qualification on the substitute parts?

A: AEC-Q200 is an automotive industry qualification standard for passive components. AC2010FK-0786K6L and ERJ-12SF8662U both carry this certification, indicating compliance with automotive reliability and environmental stress testing requirements. The RC5025F8662CS does not specify this qualification, making the substitutes suitable for automotive applications requiring this certification level.

Q: Are moisture resistant characteristics maintained across all substitute options?

A: Yes. All three components (RC5025F8662CS, AC2010FK-0786K6L, and ERJ-12SF8662U) maintain Moisture Sensitivity Level 1 (Unlimited) classification, indicating no moisture sensitivity restrictions. Moisture resistant thick film composition is consistent across all options.
