Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT0805FRE07309KL is determined by the following mandatory parameters:

• Resistance value: 309 kOhms (exact match required)
• Package: 0805 (2012 Metric) (exact match required)
• Composition: Thin Film (exact match required)
• Operating temperature range: -55°C to 155°C minimum (equal or wider range acceptable)
• RoHS compliance: ROHS3 Compliant (required)
• MSL rating: 1 (Unlimited) (required)

Tolerance and power rating may vary within acceptable substitution parameters. Tighter tolerance specifications (±0.1% vs ±1%) and higher power ratings (0.25W vs 0.125W) represent upgrades. Temperature coefficient improvements are secondary parameters that do not restrict substitution eligibility.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard PCB assembly and storage requirements.

RT0805BRD07309KL and ERA-6AEB3093V offer improved tolerance specifications (±0.1% vs ±1%) and reduced temperature coefficient (±25ppm/°C vs ±50ppm/°C), suitable for precision analog circuits requiring tighter component matching.

4-2176094-0 provides increased power dissipation capability (0.25W vs 0.125W) while maintaining the 0805 package footprint, applicable to circuits with higher current or thermal stress conditions.

ERA-6AEB3093V carries AEC-Q200 automotive qualification, required for automotive applications subject to automotive reliability and environmental standards.

Frequently Asked Questions (FAQ)

Q: Can RT0805BRD07309KL replace RT0805FRE07309KL in any application?

A: Yes. RT0805BRD07309KL is electrically and mechanically compatible. It provides superior tolerance (±0.1% vs ±1%) and lower temperature coefficient (±25ppm/°C vs ±50ppm/°C) at identical power rating and package dimensions.

Q: Is 4-2176094-0 suitable for direct substitution?

A: Yes, with consideration for thermal design. 4-2176094-0 maintains identical resistance, tolerance, and package but provides double the power rating (0.25W vs 0.125W). Physical height increases from 0.024" to 0.026", which may affect PCB clearance in space-constrained layouts.

Q: When should ERA-6AEB3093V be selected?

A: ERA-6AEB3093V is required for automotive applications requiring AEC-Q200 certification. It is electrically equivalent to RT0805BRD07309KL with identical tolerance and temperature coefficient specifications.

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

A: Yes. All listed parts are supplied in Tape & Reel (TR) packaging suitable for automated assembly processes.

Q: What is the impact of tolerance differences on circuit performance?

A: Tolerance differences affect component matching and circuit accuracy. ±1% tolerance (RT0805FRE07309KL) is suitable for general-purpose applications. ±0.1% tolerance (RT0805BRD07309KL, 4-2176094-0, ERA-6AEB3093V) is required for precision analog circuits, filters, and reference networks where component matching is critical.
