Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following mandatory parameters:

• Resistance Value: All substitutes must be 430 kOhms
• Package Format: All substitutes must be 0805 (2012 Metric)
• Power Rating: All substitutes must be rated 0.125W (1/8W) minimum
• Composition: All substitutes must be thin film construction
• Operating Temperature Range: All substitutes must support -55°C ~ 155°C
• Termination Count: All substitutes must have 2 terminations
• Compliance: All substitutes must be ROHS3 compliant and REACH unaffected

Tolerance, temperature coefficient, and automotive qualification are secondary parameters that define upgrade or specialized application paths. Parts with tighter tolerance (±0.1% or ±0.5%) and lower temperature coefficient (±25ppm/°C) represent performance upgrades. Parts with AEC-Q200 automotive qualification and anti-sulfur features address specific environmental or reliability requirements.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitution (Equivalent Performance)

RT0805DRE07430KL serves as a direct substitute with improved tolerance (±0.5% vs ±1%) while maintaining the same temperature coefficient and operating range. This part is suitable for applications where tighter resistance tolerance is beneficial without requiring automotive qualification.

Performance Upgrade (Enhanced Specifications)

RT0805BRD07430KL and ERA-6AEB434V both provide ±0.1% tolerance and ±25ppm/°C temperature coefficient, representing a performance upgrade from the original ±1% tolerance specification. ERA-6AEB434V adds AEC-Q200 automotive qualification for applications requiring automotive-grade reliability.

Specialized Application (Automotive & Environmental)

RG2012P-434-B-T5 combines AEC-Q200 automotive qualification with anti-sulfur protection, addressing corrosive environments and automotive reliability requirements. This part also features a reduced seated height (0.020" vs 0.024"), which may be relevant for space-constrained applications.

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and full compatibility with the original 0805 package footprint and solder reflow processes.

Frequently Asked Questions (FAQ)

Q: Can RT0805DRE07430KL replace RT0805FRE07430KL in any application?

A: Yes. RT0805DRE07430KL is electrically and mechanically compatible. It offers improved tolerance (±0.5% vs ±1%) while maintaining identical power rating, package format, and operating temperature range. No circuit redesign is required.

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

A: The RT0805FRE07430KL (±1%, ±50ppm/°C) and RT0805DRE07430KL (±0.5%, ±50ppm/°C) differ in tolerance specification. The RT0805BRD07430KL (±0.1%, ±25ppm/°C) represents the highest precision option within the YAGEO RT series, with tighter tolerance and lower temperature coefficient.

Q: When should I use ERA-6AEB434V or RG2012P-434-B-T5?

A: Use ERA-6AEB434V or RG2012P-434-B-T5 when AEC-Q200 automotive qualification is required by design specification or application standard. RG2012P-434-B-T5 is additionally specified for environments with sulfur exposure risk. Both parts provide ±0.1% tolerance and ±25ppm/°C temperature coefficient.

Q: Are all substitute parts available in the same packaging format?

A: Yes. All substitute parts are supplied in 0805 (2012 Metric) package format with Tape & Reel (TR) packaging. They are compatible with standard SMD assembly processes and reflow soldering profiles.

Q: Does package height variation affect PCB assembly compatibility?

A: RG2012P-434-B-T5 has a maximum seated height of 0.020" compared to 0.024" for other parts. This 0.004" difference is negligible for standard PCB assembly and does not affect reflow soldering or component placement. Verify clearance only if height-constrained applications are specified.

Q: Are all parts ROHS3 compliant?

A: Yes. All listed parts, including the main part and all substitutes, are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
