Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment of the following parameters:

• Resistance value: 12 kOhms
• Tolerance: ±1%
• Power rating: 0.75W
• Package: 2010 (5025 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Number of terminations: 2
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

The identified substitute parts RC2010FK-0712KL (YAGEO) and RMCF2010FT12K0 (Stackpole Electronics Inc) meet all electrical and mechanical requirements for direct substitution. Physical dimensions remain within acceptable tolerances for PCB assembly compatibility.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status and full RoHS3 compliance. The ERJ-S1DF1202U and RMCF2010FT12K0 both carry AEC-Q200 automotive qualification, making them functionally equivalent for automotive applications. The RC2010FK-0712KL provides moisture-resistant construction as an alternative feature set while maintaining identical electrical specifications and compliance certifications.

Selection between these parts should be based on supply chain availability, lead time requirements, and specific application certifications. All three parts are suitable for direct PCB assembly replacement without design modification.

Frequently Asked Questions (FAQ)

Q: Can RC2010FK-0712KL replace ERJ-S1DF1202U in automotive applications?

A: RC2010FK-0712KL meets all electrical and mechanical specifications for direct substitution. However, it does not carry AEC-Q200 certification. For applications requiring automotive qualification, RMCF2010FT12K0 is the appropriate substitute.

Q: Are there dimensional compatibility concerns when substituting these parts?

A: All three parts share identical length and width dimensions (5.00mm x 2.50mm). The seated height varies slightly: ERJ-S1DF1202U and RMCF2010FT12K0 at 0.028" (0.70mm), and RC2010FK-0712KL at 0.026" (0.65mm). These variations remain within standard PCB assembly tolerances.

Q: Do all substitute parts meet the same compliance standards?

A: All three parts are ROHS3 compliant, REACH unaffected, and classified as MSL 1 (Unlimited moisture sensitivity level). The primary compliance difference is AEC-Q200 automotive qualification, present in the original ERJ-S1DF1202U and RMCF2010FT12K0 but absent in RC2010FK-0712KL.

Q: What is the basis for substitution eligibility?

A: Substitution is based on matching resistance value (12 kOhms), tolerance (±1%), power rating (0.75W), package type (2010), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and compliance certifications.
