Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AF2010JK-074M7L is determined by the following critical parameters:

• Resistance Value: Must be 4.7 MOhms
• Package / Case: Must be 2010 (5025 Metric) for mechanical and thermal compatibility
• Power Rating: Must be 0.75W minimum
• Composition: Thick film construction
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C minimum
• Number of Terminations: 2-terminal configuration
• RoHS Compliance: ROHS3 Compliant

The RC2010FK-074M7L qualifies as a substitute part because it maintains all critical electrical and mechanical parameters. The tolerance specification differs (±1% versus ±5%), which represents an improvement in precision and does not restrict substitution in applications designed for the original ±5% tolerance.

Parameter Comparison

Engineering Selection Recommendations

Both the AF2010JK-074M7L and RC2010FK-074M7L are active production components with ROHS3 compliance and MSL Level 1 rating. The RC2010FK-074M7L offers improved tolerance specification (±1% versus ±5%) while maintaining identical electrical performance, power rating, and thermal characteristics. Both parts are suitable for applications requiring 2010 package format resistors with 4.7 MOhms resistance and 0.75W power dissipation across the -55°C to 155°C operating range. Selection between these parts depends on application-specific tolerance requirements and inventory availability.

Frequently Asked Questions (FAQ)

Q: Can RC2010FK-074M7L replace AF2010JK-074M7L in existing designs?

A: Yes. The RC2010FK-074M7L maintains identical resistance value, power rating, package format, and operating temperature range. The improved tolerance specification (±1% versus ±5%) does not restrict substitution in circuits designed for the original part.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts use the 2010 (5025 Metric) package with dimensions of 0.197" L x 0.098" W (5.00mm x 2.50mm) and maximum seated height of 0.026" (0.65mm). They are mechanically interchangeable.

Q: What is the difference between AF and RC series designations?

A: The AF2010JK-074M7L belongs to the AF series with anti-sulfur and automotive AEC-Q200 features. The RC2010FK-074M7L belongs to the RC_L series with moisture-resistant characteristics. Both are thick film resistors from YAGEO with identical electrical specifications for this resistance value and power rating.

Q: Are both parts suitable for automotive applications?

A: The AF2010JK-074M7L carries AEC-Q200 automotive qualification. The RC2010FK-074M7L does not list AEC-Q200 in the provided specifications. Application requirements for automotive qualification should be verified against design specifications.

Q: What is the significance of the tolerance difference?

A: The RC2010FK-074M7L tolerance of ±1% provides tighter resistance value control compared to the AF2010JK-074M7L tolerance of ±5%. Applications designed for ±5% tolerance will operate within specification with the ±1% substitute part.
