RT0805FRD07124KL Equivalent & Substitute Parts

Part Overview

The RT0805FRD07124KL is a 124 kOhms ±1% thin film chip resistor in 0805 (2012 Metric) package rated at 0.125W (1/8W) power dissipation. Manufactured by YAGEO, this component is actively produced and ROHS3 compliant. Substitute parts are identified for applications requiring improved tolerance specifications, higher power ratings, or automotive-grade certifications while maintaining the same resistance value, package footprint, and core electrical characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Core Compatibility Requirements (Must Match):

• Resistance value: 124 kOhms
• Package / Case: 0805 (2012 Metric)
• Composition: Thin Film
• Temperature Coefficient: ±25ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variations:

• Tolerance: May be equal to or tighter than ±1%
• Power Rating: May be equal to or higher than 0.125W
• Manufacturer: Different manufacturers permitted
• Certifications: Additional certifications (AEC-Q200) permitted
• Features: Additional features (Anti-Sulfur) permitted

All substitute parts listed meet or exceed the electrical and mechanical specifications of the main part while maintaining full package and footprint compatibility.

Parameter Comparison

Engineering Selection Recommendations

RT0805BRD07124KL (YAGEO): Direct upgrade from the main part with tighter tolerance (±0.1% vs ±1%) while maintaining identical power rating, package, and operating specifications. Recommended for applications requiring improved accuracy without changing component footprint or thermal characteristics.

2176094-4 (TE Connectivity): Substitute with higher power rating (0.25W vs 0.125W) and tighter tolerance (±0.1%). Suitable for applications with increased thermal dissipation requirements. Height specification differs slightly (0.026" vs 0.024" maximum seated height); verify PCB clearance in space-constrained layouts.

ERA-6AEB1243V (Panasonic): Automotive-grade substitute with AEC-Q200 certification, tighter tolerance (±0.1%), and identical power rating. Appropriate for automotive and high-reliability applications requiring formal automotive qualification.

RG2012P-1243-B-T5 (Susumu): Automotive-grade substitute with AEC-Q200 certification, Anti-Sulfur feature, and tighter tolerance (±0.1%). Lowest seated height (0.020" maximum) provides advantage in space-constrained designs. Highest inventory availability among substitutes.

All substitute parts maintain full electrical and mechanical compatibility with the RT0805FRD07124KL within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can RT0805BRD07124KL replace RT0805FRD07124KL in any application?

A: Yes. RT0805BRD07124KL is a direct substitute with identical package, power rating, and operating temperature range. The tighter tolerance (±0.1% vs ±1%) represents an improvement and does not restrict compatibility.

Q: What is the primary difference between 2176094-4 and other substitutes?

A: 2176094-4 has a higher power rating (0.25W vs 0.125W) and slightly greater maximum seated height (0.026" vs 0.024"). Use this part when thermal dissipation requirements exceed the original specification or when higher power handling is needed.

Q: Are ERA-6AEB1243V and RG2012P-1243-B-T5 interchangeable?

A: Yes, both are automotive-grade substitutes with AEC-Q200 certification, ±0.1% tolerance, and 0.125W power rating in 0805 package. RG2012P-1243-B-T5 includes Anti-Sulfur feature and has lower seated height (0.020" vs 0.024"). Selection depends on specific environmental requirements and available inventory.

Q: Can I use an automotive-grade part (ERA-6AEB1243V or RG2012P-1243-B-T5) in non-automotive applications?

A: Yes. Automotive-grade parts meet or exceed standard industrial specifications and are fully compatible with non-automotive applications. No performance degradation occurs.

Q: Does package footprint differ between substitutes?

A: All substitutes use 0805 (2012 Metric) package with identical length (0.079") and width (0.049"). Maximum seated height varies slightly: RT0805FRD07124KL, RT0805BRD07124KL, and ERA-6AEB1243V are 0.024"; 2176094-4 is 0.026"; RG2012P-1243-B-T5 is 0.020". Verify clearance in height-constrained PCB designs.

Q: Are all parts ROHS3 compliant?

A: Yes. All listed parts are ROHS3 compliant and suitable for applications with RoHS requirements.
