Substitute Part Grouping Explanation

Substitution eligibility for the RT0402FRE0735K7L is determined by the following criteria:

• Identical resistance value: 35.7 kOhms
• Equal or tighter tolerance: ±1% or better
• Identical package: 0402 (1005 Metric)
• Identical power rating: 0.063W (1/16W)
• Identical composition: Thin Film
• Compatible operating temperature range: -55°C to 155°C minimum
• Equivalent or superior moisture sensitivity rating: MSL 1
• ROHS3 compliance maintained

All substitute parts listed meet these criteria. Tolerance improvements (from ±1% to ±0.1%) represent upgrades suitable for applications requiring higher precision. Temperature coefficient variations and automotive certifications are noted for application-specific selection.

Parameter Comparison

Engineering Selection Recommendations

RT0402BRE0735K7L (YAGEO) is the direct upgrade path within the same manufacturer series, offering improved tolerance (±0.1%) while maintaining identical thermal and mechanical specifications. This option is suitable for applications requiring higher precision without introducing new supplier dependencies.

CPF0402B35K7E1 (TE Connectivity) provides equivalent tolerance performance with improved temperature coefficient (±25ppm/°C versus ±50ppm/°C), beneficial for temperature-sensitive applications. This part maintains standard industrial compliance.

ERA-2AEB3572X (Panasonic) is specified for automotive applications requiring AEC-Q200 certification. The slightly increased seated height (0.40mm versus 0.35mm) must be verified against PCB layout constraints. This part is suitable only when automotive-grade reliability is a design requirement.

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

Frequently Asked Questions (FAQ)

Q: Can RT0402BRE0735K7L replace RT0402FRE0735K7L in any application?

A: Yes. RT0402BRE0735K7L is electrically and mechanically compatible. The improved tolerance (±0.1% versus ±1%) makes it suitable for all applications where the original part functions, with no design modifications required.

Q: What is the primary difference between CPF0402B35K7E1 and RT0402BRE0735K7L?

A: Both offer ±0.1% tolerance and identical package dimensions. CPF0402B35K7E1 has a superior temperature coefficient (±25ppm/°C versus ±50ppm/°C), making it preferable for circuits with tight temperature stability requirements. Manufacturer sourcing and lead time may differ.

Q: When should ERA-2AEB3572X be selected?

A: ERA-2AEB3572X is specified when AEC-Q200 automotive certification is required by design or regulatory standards. The 0.40mm seated height must be confirmed compatible with PCB assembly specifications before substitution.

Q: Are all substitute parts available in Tape & Reel packaging?

A: Yes. All listed substitute parts are supplied in Tape & Reel (TR) packaging, maintaining compatibility with automated assembly processes.

Q: Does tolerance improvement affect circuit performance negatively?

A: No. Tighter tolerance (±0.1%) represents improved component consistency and is compatible with all applications designed for ±1% tolerance. No circuit redesign is necessary.

Q: What is the impact of temperature coefficient differences?

A: CPF0402B35K7E1 and ERA-2AEB3572X have ±25ppm/°C versus the original ±50ppm/°C. This means resistance variation over temperature is reduced by half, beneficial for precision analog circuits but not detrimental if the original specification is met.
