Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT0805FRE0718R2L is determined by the following critical parameters:

• Resistance Value: Must be 18.2 Ohms (exact match required)
• Package Type: Must be 0805 (2012 Metric) for mechanical and electrical compatibility
• Composition: Thin film construction ensures performance characteristics suitable for precision applications
• Operating Temperature Range: Must support -55°C to 155°C minimum
• Termination Count: Must be 2-terminal configuration

The identified substitute part TE Connectivity 5-1625868-2 meets these core substitution criteria. However, it introduces variations in tolerance, power rating, temperature coefficient, and compliance status that must be evaluated for specific application requirements.

Engineering Selection Recommendations

RT0805FRE0718R2L (YAGEO) is the primary selection for applications requiring ROHS3 compliance and standard precision tolerance specifications. This part is actively produced with established supply availability.

5-1625868-2 (TE Connectivity) serves as a substitute where the following conditions are met:

• Applications do not require RoHS compliance
• Enhanced tolerance (±0.1% vs ±1%) provides improved precision
• Higher power dissipation capability (0.25W vs 0.125W) is beneficial
• Lower temperature coefficient (±25ppm/°C vs ±50ppm/°C) improves thermal stability
• Mechanical compatibility is confirmed despite 0.002" (0.05mm) height difference

Selection between these parts must be based on specific application compliance requirements and performance specifications.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 5-1625868-2 be used as a direct replacement for the YAGEO RT0805FRE0718R2L?

A: Mechanical and electrical substitution is possible due to identical resistance value, package type, and operating temperature range. However, RoHS compliance status differs. Verify compliance requirements for your application before substitution.

Q: What is the significance of the tolerance difference (±1% vs ±0.1%)?

A: The TE Connectivity substitute provides tighter tolerance, resulting in more precise resistance values. This is advantageous for precision measurement and signal conditioning circuits but is not required for general-purpose applications.

Q: Does the higher power rating of the substitute part affect circuit performance?

A: The 0.25W rating of the substitute provides greater thermal margin compared to the 0.125W original specification. This does not negatively impact circuit performance and may improve reliability in thermally demanding environments.

Q: Are there physical compatibility concerns between these parts?

A: Both parts use identical 0805 (2012 Metric) packages with identical length and width. The height difference of 0.002" (0.05mm) is negligible for standard PCB assembly and does not affect electrical performance or mechanical fit.

Q: What does the temperature coefficient difference mean for my application?

A: The TE Connectivity substitute has a lower temperature coefficient (±25ppm/°C vs ±50ppm/°C), meaning its resistance value changes less with temperature variations. This provides improved stability in temperature-sensitive applications.

Q: Why is RoHS compliance important for this substitution?

A: RoHS compliance is a regulatory requirement in many markets and industries. If your application or end-use region requires RoHS certification, the YAGEO RT0805FRE0718R2L is the appropriate selection. The TE Connectivity substitute is not RoHS compliant.
