Substitute Part Grouping Explanation

Substitution eligibility for the CRCW08052R37FKTA is determined by strict equivalence across the following parameters:

• Resistance value: 2.37 Ohms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Package: 0805 (2012 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Automotive qualification: AEC-Q200
• Termination count: 2
• Physical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm)
• Height: 0.020" (0.50mm) maximum

The CRCW08052R37FKEA meets all these criteria and is classified as a direct equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

Both CRCW08052R37FKTA and CRCW08052R37FKEA are active production parts from Vishay Dale with identical electrical and mechanical specifications. The primary distinction lies in regulatory compliance status. The CRCW08052R37FKEA carries ROHS3 compliance and REACH Unaffected status, whereas the CRCW08052R37FKTA is RoHS non-compliant and REACH Affected. Selection between these parts should be based on applicable regulatory requirements for the end application and regional market constraints.

Frequently Asked Questions (FAQ)

Q: Can CRCW08052R37FKEA be used as a direct replacement for CRCW08052R37FKTA?

A: Yes. Both parts share identical electrical characteristics (2.37 Ohms ±1%, 0.125W), thermal properties (±100ppm/°C, -55°C ~ 155°C), mechanical dimensions (0805 package, 2.00mm x 1.25mm), and automotive qualification (AEC-Q200). They are functionally interchangeable at the circuit level.

Q: What is the difference between these two part numbers?

A: The parts are electrically and mechanically identical. The difference is in regulatory compliance: CRCW08052R37FKEA is ROHS3 compliant and REACH Unaffected, while CRCW08052R37FKTA is RoHS non-compliant and REACH Affected.

Q: Are both parts suitable for automotive applications?

A: Yes. Both parts carry AEC-Q200 automotive qualification and operate across the -55°C ~ 155°C temperature range required for automotive use.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes. Both parts use identical 0805 (2012 Metric) packaging with the same physical dimensions (0.079" L x 0.049" W, 0.020" maximum height) and are supplied in Tape & Reel format. No PCB layout or assembly process modifications are required.

Q: Which part should be selected for new designs?

A: Selection depends on regulatory requirements. For applications requiring ROHS3 compliance or REACH compliance, use CRCW08052R37FKEA. For applications without these constraints, either part is acceptable based on availability and supply chain considerations.
