Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S1DF51R0U is determined by strict alignment of the following parameters:

• Resistance value: 51 Ohms
• Tolerance: ±1%
• Power rating: 0.75W (3/4W)
• Package: 2010 (5025 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Termination count: 2
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

The RC2010FK-0751RL from YAGEO meets all these criteria and qualifies as a direct substitute. Differences in physical features (height seated maximum) and specific feature sets (moisture resistant versus anti-sulfur) do not affect functional equivalence within the specified electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the ERJ-S1DF51R0U and RC2010FK-0751RL are active production components with ROHS3 compliance and identical electrical specifications. The RC2010FK-0751RL from YAGEO provides higher inventory availability (6118 units in stock versus 788 units for the Panasonic part). Both components meet the same regulatory and environmental standards. Selection between these parts should be based on supply chain requirements, lead time considerations, and inventory availability rather than technical performance differences.

Frequently Asked Questions (FAQ)

Q: Can RC2010FK-0751RL be used as a direct replacement for ERJ-S1DF51R0U?

A: Yes. Both parts share identical electrical specifications (51 Ohms ±1%, 0.75W), the same package dimensions (2010 / 5025 Metric), equivalent temperature performance (±100ppm/°C, -55°C ~ 155°C operating range), and matching compliance certifications (ROHS3, MSL 1).

Q: What is the difference in height between these two parts?

A: The ERJ-S1DF51R0U has a maximum seated height of 0.028" (0.70mm), while the RC2010FK-0751RL measures 0.026" (0.65mm) maximum. This 0.002" (0.05mm) difference is within typical PCB assembly tolerances and does not affect functional compatibility.

Q: Are there differences in feature sets between these parts?

A: The ERJ-S1DF51R0U includes anti-sulfur properties and automotive AEC-Q200 qualification. The RC2010FK-0751RL features moisture-resistant construction. Both parts maintain MSL 1 (Unlimited) moisture sensitivity ratings and operate across the same temperature range. Feature differences do not impact electrical performance or substitution eligibility.

Q: Do both parts meet automotive standards?

A: The ERJ-S1DF51R0U carries AEC-Q200 automotive qualification. The RC2010FK-0751RL does not list AEC-Q200 certification in the provided specifications. Applications requiring explicit AEC-Q200 compliance should use the ERJ-S1DF51R0U.

Q: What are the compliance and regulatory statuses?

A: Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8533.21.0030. Both carry MSL 1 (Unlimited) moisture sensitivity ratings.
