Substitute Part Grouping Explanation

Substitution eligibility for the CRCW08058M45FKTA is determined by strict equivalence across the following parameters:

• Resistance value: 8.45 MOhms
• 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
• Termination count: 2
• Moisture sensitivity level: 1 (Unlimited)
• Automotive qualification: AEC-Q200

The CRCW08058M45FKEA qualifies as a direct substitute because it maintains identical electrical and mechanical specifications across all critical parameters. Differences in RoHS compliance status and REACH classification do not affect functional interchangeability in applications where the original part is specified.

Parameter Comparison

Engineering Selection Recommendations

Both CRCW08058M45FKTA and CRCW08058M45FKEA are active production components from Vishay Dale with identical electrical and mechanical specifications. The CRCW08058M45FKEA offers improved regulatory compliance, meeting ROHS3 standards and carrying REACH Unaffected status, compared to the CRCW08058M45FKTA which is RoHS non-compliant and REACH Affected. Both parts maintain AEC-Q200 automotive qualification and are suitable for applications requiring high-impedance resistive elements in automotive or industrial environments operating across the -55°C to 155°C temperature range.

Frequently Asked Questions (FAQ)

Q: Can CRCW08058M45FKEA be used as a direct replacement for CRCW08058M45FKTA?

A: Yes. Both parts share identical resistance value (8.45 MOhms), tolerance (±1%), power rating (0.125W), package (0805), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and AEC-Q200 automotive qualification. Physical dimensions and termination configuration are identical.

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

A: The primary differences are regulatory compliance classifications. CRCW08058M45FKEA is ROHS3 compliant and REACH Unaffected, while CRCW08058M45FKTA is RoHS non-compliant and REACH Affected. Electrical and mechanical performance are equivalent.

Q: Are there any package or footprint differences?

A: No. Both parts use the 0805 (2012 Metric) package with identical dimensions of 0.079" L x 0.049" W (2.00mm x 1.25mm) and maximum seated height of 0.020" (0.50mm). PCB footprints are interchangeable.

Q: Which part should be selected for new designs?

A: Selection depends on regulatory requirements. For applications requiring ROHS3 compliance or REACH compliance, CRCW08058M45FKEA is the appropriate choice. For applications without these regulatory constraints, either part is functionally equivalent.

Q: Is inventory availability a factor in substitution?

A: CRCW08058M45FKEA has higher inventory availability (7451 pieces) compared to CRCW08058M45FKTA (936 pieces). This may influence procurement decisions based on lead time and supply chain requirements.
