Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

• Identical resistance value: 90.9 Ohms
• Equal or superior tolerance: ±1% or better
• Identical or superior power rating: 0.063W minimum
• Identical package: 0402 (1005 Metric)
• Identical composition: Thin Film
• Compatible operating temperature range: -55°C to 155°C minimum
• ROHS3 compliance maintained
• MSL rating of 1 (Unlimited) or equivalent

All substitute parts listed meet or exceed these parameters. Tolerance upgrades from ±1% to ±0.1% represent improved precision without functional incompatibility.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain Active product status and ROHS3 compliance. Selection between substitutes depends on application-specific requirements:

RT0402BRD0790R9L (YAGEO) provides tolerance upgrade to ±0.1% with improved temperature coefficient (±25ppm/°C) while maintaining identical package dimensions and YAGEO series continuity.

CPF0402B90R9E1 (TE Connectivity Passive Product) offers ±0.1% tolerance and ±25ppm/°C temperature coefficient with equivalent mechanical fit.

ERA-2AEB90R9X (Panasonic) provides ±0.1% tolerance with AEC-Q200 automotive qualification and ±25ppm/°C temperature coefficient. Height is 0.40mm maximum versus 0.35mm for other options.

RN73C1E90R9BTDF (TE Connectivity) delivers superior temperature coefficient performance at ±10ppm/°C with ±0.1% tolerance, suitable for precision applications requiring minimal thermal drift.

Frequently Asked Questions (FAQ)

Q: Can RT0402BRD0790R9L replace RT0402FRE0790R9L directly?

A: Yes. Both parts share identical resistance (90.9 Ω), power rating (0.063W), package (0402), and operating temperature range (-55°C to 155°C). The substitute offers improved tolerance (±0.1% versus ±1%) and lower temperature coefficient (±25ppm/°C versus ±50ppm/°C), making it functionally compatible and superior for precision applications.

Q: What is the difference between ERA-2AEB90R9X and other substitutes?

A: ERA-2AEB90R9X includes AEC-Q200 automotive qualification and is manufactured by Panasonic. The maximum seated height is 0.40mm compared to 0.35mm for other options. All other electrical parameters remain equivalent.

Q: Is RN73C1E90R9BTDF suitable for high-precision circuits?

A: RN73C1E90R9BTDF features the lowest temperature coefficient (±10ppm/°C) among all listed options, making it appropriate for applications requiring minimal thermal drift. It maintains ±0.1% tolerance and identical package specifications.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL rating of 1 (Unlimited), ensuring compatibility with standard manufacturing and storage requirements.

Q: Can substitutes be mixed in the same circuit board assembly?

A: Yes. All substitutes meet identical mechanical and electrical specifications for the 0402 package footprint. Mixed sourcing is permissible provided design tolerances accommodate the specified tolerance ranges.
