RT0603FRE0793R1L Equivalent & Substitute Parts

Part Overview

The RT0603FRE0793R1L is a 93.1 Ohm ±1% thin film chip resistor in 0603 (1608 Metric) package rated at 0.1W (1/10W) power dissipation. Manufactured by YAGEO under the RT series, this component is actively produced and widely used in general-purpose electronic applications. The part is ROHS3 compliant with MSL 1 rating, indicating unlimited moisture sensitivity protection.

Equivalent and substitute parts are identified when they maintain the same resistance value, package form factor, and operating temperature range while meeting or exceeding the electrical specifications of the original component. Substitutes may offer improved tolerance, higher power ratings, or enhanced reliability certifications.

Substitute Part Grouping Explanation

Substitute parts for the RT0603FRE0793R1L are qualified based on the following criteria:

Mandatory Compatibility Parameters:

• Resistance value: 93.1 Ohms (exact match)
• Package form factor: 0603 (1608 Metric)
• Operating temperature range: -55°C ~ 155°C (minimum)
• Composition: Thin Film
• Number of terminations: 2

Allowable Variations:

• Tolerance: Equal to or better than ±1%
• Power rating: Equal to or greater than 0.1W
• Temperature coefficient: Equal to or better than ±50ppm/°C
• Compliance certifications: Equal to or exceeding ROHS3

Two substitute parts meet these criteria: ERA-3AEB93R1V (Panasonic) and RP73PF1J93R1BTDF (TE Connectivity). Both maintain identical resistance, package, and operating temperature specifications while offering improved tolerance (±0.1%) and lower temperature coefficients (±25ppm/°C).

Parameter Comparison

Engineering Selection Recommendations

RT0603FRE0793R1L (YAGEO): Primary choice for general-purpose applications where ±1% tolerance and standard thin film performance are acceptable. Active production status ensures long-term availability.

ERA-3AEB93R1V (Panasonic): Recommended for applications requiring improved tolerance (±0.1%) and lower temperature coefficient (±25ppm/°C). Includes AEC-Q200 automotive qualification, suitable for automotive and high-reliability applications. Identical power rating and package specifications ensure direct substitution.

RP73PF1J93R1BTDF (TE Connectivity): Suitable for applications requiring higher power dissipation capability (0.167W vs. 0.1W) while maintaining ±0.1% tolerance and ±25ppm/°C temperature coefficient. Slightly smaller physical dimensions (1.55mm L vs. 1.60mm L) may require PCB layout verification in space-constrained designs.

All three parts maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard manufacturing and storage conditions.

Frequently Asked Questions (FAQ)

Q: Can ERA-3AEB93R1V replace RT0603FRE0793R1L in existing designs? A: Yes. Both parts share identical resistance (93.1 Ohms), package (0603), operating temperature range (-55°C ~ 155°C), and power rating (0.1W). ERA-3AEB93R1V offers superior tolerance (±0.1% vs. ±1%) and lower temperature coefficient (±25ppm/°C vs. ±50ppm/°C), making it a direct upgrade with no circuit modifications required.

Q: What is the difference between RP73PF1J93R1BTDF and the other substitutes? A: RP73PF1J93R1BTDF provides higher power dissipation (0.167W vs. 0.1W) and improved tolerance (±0.1%), but has slightly different physical dimensions (1.55mm L vs. 1.60mm L). This may require PCB layout verification in space-constrained applications. All other electrical and thermal specifications remain compatible.

Q: Are all three parts suitable for automotive applications? A: ERA-3AEB93R1V carries AEC-Q200 automotive qualification. RT0603FRE0793R1L and RP73PF1J93R1BTDF do not list automotive certifications in their specifications. For automotive applications, ERA-3AEB93R1V is the qualified choice.

Q: Do these substitutes require any circuit design changes? A: No. All three parts maintain identical resistance values, package form factors, and operating temperature ranges. Direct PCB footprint compatibility is assured for RT0603FRE0793R1L and ERA-3AEB93R1V. RP73PF1J93R1BTDF has slightly different length (1.55mm vs. 1.60mm) and should be evaluated for layout fit.

Q: What is the significance of the ±0.1% tolerance improvement? A: Improved tolerance reduces resistance value variation across the production batch. For precision analog circuits, signal conditioning, or measurement applications, ±0.1% tolerance provides tighter control over circuit performance compared to ±1% tolerance.

Q: Are moisture sensitivity levels identical across all three parts? A: Yes. All three parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. Standard storage and handling procedures apply equally to all three components.
