Substitute Part Grouping Explanation

Substitute parts for the RT0402FRE0793K1L are qualified based on the following criteria:

• Identical resistance value: 93.1 kOhms
• Identical package: 0402 (1005 Metric)
• Identical power rating: 0.063W (1/16W)
• Identical composition: Thin Film
• Identical operating temperature range: -55°C ~ 155°C
• Identical RoHS and MSL compliance

The identified substitutes maintain all critical electrical and mechanical parameters. Variations in tolerance and temperature coefficient do not prevent substitution when the application requirements are met by the substitute's specifications.

Parameter Comparison

Engineering Selection Recommendations

CPF0402B93K1E1 (TE Connectivity Passive Product) is a direct substitute offering improved tolerance specification (±0.1% versus ±1%) and lower temperature coefficient (±25ppm/°C versus ±50ppm/°C) while maintaining identical package, power rating, and compliance certifications. This part is suitable for applications requiring tighter resistance accuracy.

ERA-2AEB9312X (Panasonic Electronic Components) is a substitute qualified to AEC-Q200 automotive standard. It provides the same tolerance and temperature coefficient improvements as the TE Connectivity part while adding automotive-grade reliability certification. The seated height is 0.016" (0.40mm) compared to 0.014" (0.35mm) for the primary part. This part is appropriate for automotive and high-reliability applications.

Both substitutes maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard manufacturing and storage conditions.

Frequently Asked Questions (FAQ)

Q: Can CPF0402B93K1E1 be used as a direct replacement for RT0402FRE0793K1L?

A: Yes. Both parts share identical resistance value (93.1 kOhms), package (0402), power rating (0.063W), and operating temperature range (-55°C ~ 155°C). The CPF0402B93K1E1 offers superior tolerance (±0.1% versus ±1%) and lower temperature coefficient, making it functionally compatible and electrically superior for most applications.

Q: What is the difference between the two substitute parts?

A: CPF0402B93K1E1 is a general-purpose thin film resistor. ERA-2AEB9312X is qualified to AEC-Q200 automotive standard and is intended for automotive and high-reliability applications. Both offer identical electrical specifications (93.1 kOhms ±0.1%, ±25ppm/°C). The ERA-2AEB9312X has a maximum seated height of 0.016" (0.40mm) versus 0.014" (0.35mm) for the other parts.

Q: Are there any package compatibility concerns?

A: All three parts use the 0402 (1005 Metric) package with identical length and width (0.039" x 0.020"). The ERA-2AEB9312X has a slightly greater maximum seated height (0.016" versus 0.014"). Verify PCB layout clearance if height is a constraint in your application.

Q: Do all parts meet RoHS and MSL requirements?

A: Yes. All three parts are ROHS3 compliant with MSL 1 (Unlimited) rating, ensuring compatibility with standard lead-free soldering processes and storage conditions without moisture baking requirements.

Q: Which substitute should I select for a new design?

A: Selection depends on application requirements. For general-purpose circuits, CPF0402B93K1E1 provides improved tolerance and temperature stability. For automotive or high-reliability applications, ERA-2AEB9312X is the appropriate choice due to AEC-Q200 qualification.
