Key Parameters

Substitute Part Grouping Explanation

Substitution of the AF2010JK-07910RL is based on the following critical parameters that must remain constant:

• Resistance Value: 910 Ohms (exact match required)
• Package Type: 2010 (5025 Metric) (mechanical and electrical compatibility)
• Power Rating: 0.75W minimum (functional equivalence)
• Temperature Range: -55°C ~ 155°C (operational envelope)
• Composition: Thick Film (material consistency)
• Compliance: ROHS3 Compliant, MSL 1 (regulatory and environmental requirements)

The substitute part RC2010FK-07910RL meets all critical parameters. The tolerance difference (±1% vs ±5%) represents an improvement in precision and does not prevent substitution. Both parts share identical package dimensions, temperature coefficients, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both AF2010JK-07910RL and RC2010FK-07910RL are active production parts from YAGEO with full ROHS3 compliance and MSL 1 rating. The primary distinction is tolerance specification: the main part offers ±5% tolerance with anti-sulfur coating, while the substitute provides ±1% tolerance with moisture-resistant coating. Both parts maintain identical electrical performance across the specified operating temperature range and are mechanically interchangeable in 2010 package footprints. Selection between these parts depends on circuit tolerance requirements and environmental exposure conditions rather than functional limitations.

Frequently Asked Questions (FAQ)

Q: Can RC2010FK-07910RL replace AF2010JK-07910RL in existing designs?

A: Yes. Both parts share identical resistance value, power rating, package dimensions, and operating temperature range. The ±1% tolerance of the substitute part is tighter than the ±5% specification of the main part, making it functionally compatible for any application requiring the AF2010JK-07910RL.

Q: What is the difference between anti-sulfur and moisture-resistant coatings?

A: Anti-sulfur coating protects against sulfur-containing atmospheric contaminants, while moisture-resistant coating provides protection against humidity and moisture ingress. Both are thick film resistor surface treatments. Selection depends on the specific environmental exposure of the application.

Q: Are the package dimensions identical?

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 on PCB layouts designed for 2010 package resistors.

Q: Do both parts meet automotive qualification standards?

A: The AF2010JK-07910RL carries AEC-Q200 automotive qualification. The RC2010FK-07910RL does not list AEC-Q200 in the provided specifications. For automotive applications requiring AEC-Q200 certification, the AF2010JK-07910RL is the specified part.

Q: What is the inventory status for each part?

A: AF2010JK-07910RL has 1026 units in stock. RC2010FK-07910RL has 8769 units in stock. The substitute part offers significantly higher availability.
