RT0402FRE07787RL Equivalent & Substitute Parts

Part Overview

The RT0402FRE07787RL is a 787 Ohms ±1% thin film chip resistor in 0402 (1005 Metric) package manufactured by YAGEO. This surface mount device is rated for 0.063W (1/16W) power dissipation and operates across -55°C to 155°C. The part is Active status and ROHS3 compliant, making it suitable for commercial and industrial applications requiring standard tolerance precision resistors.

Substitute parts are necessary when the original part becomes unavailable, when tighter tolerance specifications are required, or when alternative manufacturers' components are preferred for supply chain diversification and cost optimization.

Substitute Part Grouping Explanation

Substitution eligibility for the RT0402FRE07787RL is determined by the following mandatory parameters:

Resistance Value: Must be 787 Ohms
Package Type: Must be 0402 (1005 Metric)
Composition: Must be Thin Film
Power Rating: Must be 0.063W (1/16W) minimum
Operating Temperature Range: Must support -55°C to 155°C
Compliance: Must maintain ROHS3 compliance

All substitute parts listed meet these core requirements. Variations in tolerance (±0.1% to ±0.5%), temperature coefficient (±10ppm/°C to ±50ppm/°C), and manufacturer certifications (such as AEC-Q200 for automotive applications) represent upgrades or alternative specifications within the same functional category.

Engineering Selection Recommendations

Direct Substitutes (Same Tolerance)

RT0402DRE07787RL maintains the ±1% tolerance specification of the original part while offering YAGEO manufacturing continuity. This part is suitable for direct replacement in applications where the original tolerance specification is required.

Upgraded Tolerance Substitutes (±0.1%)

RT0402BRD07787RL, CPF0402B787RE1, RN73C1E787RBTDF, and ERA-2AEB7870X all provide ±0.1% tolerance, representing a tighter specification than the original ±1%. These parts are electrically compatible and suitable for applications requiring improved precision. The lower temperature coefficient (±25ppm/°C or ±10ppm/°C) in these variants provides enhanced stability across the operating temperature range.

Automotive-Qualified Substitute

ERA-2AEB7870X carries AEC-Q200 automotive qualification and is suitable for automotive and high-reliability applications. The maximum seated height is 0.40mm compared to 0.35mm for other variants; verify PCB layout clearance before selection.

Supply Chain Considerations

All substitute parts maintain ROHS3 compliance and MSL 1 rating. Selection should be based on availability, lead time requirements, and specific application tolerance demands. Inventory levels vary across manufacturers; verify current stock status with suppliers.

Frequently Asked Questions (FAQ)

Q: Can RT0402DRE07787RL replace RT0402FRE07787RL directly?

A: Yes. Both parts share identical resistance (787 Ohms), power rating (0.063W), package (0402), and operating temperature range (-55°C to 155°C). RT0402DRE07787RL offers ±0.5% tolerance compared to the original ±1%, making it a compatible direct substitute.

Q: What is the difference between the YAGEO RT series variants?

A: The RT0402FRE07787RL (±1%), RT0402DRE07787RL (±0.5%), and RT0402BRD07787RL (±0.1%) differ in tolerance specification and temperature coefficient. All are thin film 0402 resistors from YAGEO with identical physical dimensions and power ratings. Selection depends on circuit tolerance requirements.

Q: Is ERA-2AEB7870X compatible with standard commercial applications?

A: Yes. ERA-2AEB7870X meets all electrical and mechanical requirements for the 0402 package. The AEC-Q200 automotive qualification is an additional certification; it does not restrict use in commercial applications. Note the maximum seated height is 0.40mm versus 0.35mm for other variants.

Q: Can I use RN73C1E787RBTDF as a substitute?

A: Yes. RN73C1E787RBTDF is a TE Connectivity thin film 0402 resistor with 787 Ohms ±0.1% tolerance. It offers the lowest temperature coefficient (±10ppm/°C) among all substitutes, providing superior thermal stability. Physical dimensions and power rating are compatible with the original part.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with modern manufacturing and environmental standards.

Q: What should I verify before selecting a substitute?

A: Confirm the required tolerance specification for your circuit design, verify PCB layout clearance for seated height (particularly for ERA-2AEB7870X at 0.40mm), and check current availability and lead times with your supplier. All listed parts are electrically and mechanically compatible within the specified parameters.
