Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S14F2742U is determined by strict equivalence across the following parameters:

• Resistance value: 27.4 kOhms
• Tolerance: ±1%
• Power rating: 0.5W (1/2W)
• Package: 1210 (3225 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Automotive compliance: AEC-Q200
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

The CRCW121027K4FKEA manufactured by Vishay Dale meets all these criteria and qualifies as a direct substitute. Both parts maintain identical electrical performance specifications and automotive qualification standards.

Parameter Comparison

Engineering Selection Recommendations

Both the ERJ-S14F2742U and CRCW121027K4FKEA are active production components with full ROHS3 compliance and AEC-Q200 automotive qualification. Selection between these parts is based on availability and supply chain requirements. The CRCW121027K4FKEA currently has higher inventory availability at 10,572 units compared to 717 units for the ERJ-S14F2742U. Both parts maintain identical electrical performance and thermal characteristics across the specified operating range. The minor difference in seated height (0.70mm versus 0.60mm) does not affect functional equivalence in standard PCB assembly applications.

Frequently Asked Questions (FAQ)

Q: Can CRCW121027K4FKEA replace ERJ-S14F2742U in automotive applications?

A: Yes. Both parts carry AEC-Q200 automotive qualification, maintain identical resistance, tolerance, power rating, and operating temperature specifications. They are mechanically compatible in 1210 package footprints.

Q: Are there differences in physical dimensions between these parts?

A: Both parts share identical length and width dimensions (3.20mm x 2.50mm). The seated height differs slightly: ERJ-S14F2742U at 0.70mm maximum versus CRCW121027K4FKEA at 0.60mm maximum. This variation does not affect standard PCB assembly compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both ERJ-S14F2742U and CRCW121027K4FKEA are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. Both are rated for -55°C to 155°C operating temperature with ±100ppm/°C temperature coefficient.

Q: What determines substitution eligibility for this resistor?

A: Substitution requires matching resistance value (27.4 kOhms), tolerance (±1%), power rating (0.5W), package type (1210), composition (thick film), temperature coefficient (±100ppm/°C), operating range (-55°C to 155°C), and automotive certification (AEC-Q200).

Q: Is the anti-sulfur feature of the ERJ-S14F2742U present in the CRCW121027K4FKEA?

A: The provided specifications for CRCW121027K4FKEA do not explicitly list anti-sulfur coating. Both parts meet AEC-Q200 automotive standards and are suitable for automotive environments.
