Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC5025F4322CS are identified based on the following substitution criteria:

Electrical Parameters (Mandatory Match):

• Resistance value: 43.2 kOhms (exact match required)
• Tolerance: ±1% (equal or tighter tolerance acceptable)
• Temperature coefficient: ±100ppm/°C (matching thermal stability)
• Operating temperature range: -55°C to 155°C (minimum coverage required)

Mechanical Parameters (Mandatory Match):

• Package format: 2010 (5025 Metric) for PCB footprint compatibility
• Composition: Thick film technology
• Number of terminations: 2 (standard chip resistor configuration)

Power Rating (Substitution Rule):

• Minimum acceptable: 0.667W (2/3W) as specified for RC5025F4322CS
• Higher power ratings are acceptable as they provide thermal margin

Compliance Parameters:

• RoHS3 compliance required
• MSL rating of 1 (Unlimited) or equivalent moisture resistance

The RMCF2010FT43K2 from Stackpole Electronics Inc qualifies as a substitute based on matching all mandatory electrical and mechanical parameters, with an increased power rating of 0.75W (3/4W) providing additional thermal capability.

Engineering Selection Recommendations

RC5025F4322CS (Samsung Electro-Mechanics):

• Primary specification for original design
• Active product status with 802 units in stock
• ROHS3 compliant and MSL 1 rated
• Suitable for applications requiring 0.667W power dissipation

RMCF2010FT43K2 (Stackpole Electronics Inc):

• Direct electrical and mechanical substitute
• Active product status with 8086 units in stock
• ROHS3 compliant and MSL 1 rated
• AEC-Q200 automotive qualification provides additional reliability assurance
• 0.75W power rating offers thermal margin above the 0.667W requirement
• Increased seated height of 0.028" (0.70mm) versus 0.026" (0.66mm) remains within standard PCB assembly tolerances

Both parts meet all mandatory substitution criteria. Selection between them depends on design requirements for automotive qualification (AEC-Q200) and thermal margin preferences.

Frequently Asked Questions (FAQ)

Q: Can RMCF2010FT43K2 replace RC5025F4322CS in existing designs?

A: Yes. Both parts share identical resistance value (43.2 kOhms), tolerance (±1%), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and 2010 package format. The RMCF2010FT43K2 has a higher power rating (0.75W versus 0.667W), which is acceptable for substitution as it provides additional thermal capability.

Q: Are there any physical compatibility concerns?

A: The seated height differs slightly: RC5025F4322CS is 0.026" (0.66mm) maximum, while RMCF2010FT43K2 is 0.028" (0.70mm) maximum. This 0.002" (0.04mm) difference is within standard PCB assembly tolerances and does not affect mechanical compatibility.

Q: What is the significance of AEC-Q200 qualification on the Stackpole part?

A: AEC-Q200 is an automotive industry standard qualification. The RMCF2010FT43K2 meets this standard, indicating it has undergone additional reliability testing and is suitable for automotive applications. This qualification is not present on the Samsung part but does not preclude use of either part in non-automotive applications.

Q: Do both parts have the same moisture sensitivity requirements?

A: Yes. Both RC5025F4322CS and RMCF2010FT43K2 are rated MSL 1 (Unlimited), meaning they have unlimited shelf life and do not require special moisture control during storage or handling.

Q: Are both parts ROHS3 compliant?

A: Yes. Both the RC5025F4322CS and RMCF2010FT43K2 are ROHS3 compliant, meeting current regulatory requirements for hazardous substance restrictions.

Q: What determines whether a part can substitute for the RC5025F4322CS?

A: Substitution requires matching of: resistance value (43.2 kOhms), tolerance (±1%), package format (2010), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and compliance certifications (ROHS3, MSL 1). Power rating must meet or exceed 0.667W.
