Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT0805FRE0748K7L is determined by the following mandatory parameters:

• Resistance value: 48.7 kOhms (exact match required)
• Package / Case: 0805 (2012 Metric) (exact match required)
• Power rating: 0.125W minimum
• Composition: Thin Film
• Operating temperature range: -55°C ~ 155°C minimum
• RoHS3 compliance

Tolerance may be equal to or tighter than ±1%. Temperature coefficient may be equal to or better than ±50ppm/°C. Automotive AEC-Q200 certification and anti-sulfur features are enhancements that do not restrict substitution but indicate suitability for specific applications.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain active product status and RoHS3 compliance. Selection between alternatives depends on application requirements:

RT0805BRD0748K7L offers improved tolerance (±0.1% vs ±1%) and better temperature coefficient (±25ppm/°C vs ±50ppm/°C) while remaining within the standard YAGEO RT series, providing a direct upgrade path for general industrial applications.

ERA-6AEB4872V provides AEC-Q200 automotive qualification with equivalent tolerance and temperature coefficient improvements, suitable for automotive and harsh environment applications requiring automotive-grade reliability.

RG2012P-4872-B-T5 combines AEC-Q200 automotive qualification with anti-sulfur protection and equivalent electrical specifications, appropriate for automotive applications in corrosive environments or high-reliability systems requiring enhanced environmental resistance.

Frequently Asked Questions (FAQ)

Q: Can RT0805BRD0748K7L replace RT0805FRE0748K7L in any application?

A: Yes. RT0805BRD0748K7L is electrically and mechanically compatible. It provides tighter tolerance (±0.1% vs ±1%) and improved temperature coefficient (±25ppm/°C vs ±50ppm/°C), making it suitable for applications where the original part is specified.

Q: What is the difference between standard and AEC-Q200 rated parts?

A: AEC-Q200 certification indicates the part meets automotive industry reliability and qualification standards. ERA-6AEB4872V and RG2012P-4872-B-T5 carry this certification, making them suitable for automotive applications. The standard RT0805FRE0748K7L and RT0805BRD0748K7L do not carry this certification.

Q: Why would I choose RG2012P-4872-B-T5 over ERA-6AEB4872V?

A: RG2012P-4872-B-T5 includes anti-sulfur protection in addition to AEC-Q200 certification. This feature is beneficial in applications exposed to sulfur-containing environments or where extended reliability in corrosive conditions is required.

Q: Are all substitute parts in the same physical package?

A: Yes. All parts use the 0805 (2012 Metric) package with identical footprint dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm). Maximum seated height varies slightly: RT0805FRE0748K7L, RT0805BRD0748K7L, and ERA-6AEB4872V are 0.024" (0.60mm); RG2012P-4872-B-T5 is 0.020" (0.50mm). This minor difference does not affect PCB assembly compatibility.

Q: Do all parts meet RoHS3 compliance?

A: Yes. All listed parts are RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, suitable for standard PCB assembly and storage conditions.
