Key Parameters

Substitute Part Grouping Explanation

Substitution of the RT0805CRE07124KL is determined by the following criteria:

Primary Matching Parameters:

• Resistance value: 124 kOhms (exact match required)
• Package form factor: 0805 (2012 Metric) (exact match required)
• Composition: Thin Film (exact match required)
• Operating temperature range: -55°C to 155°C (exact match required)

Allowable Variation Parameters:

• Tolerance: ±0.25% or tighter (±0.1% acceptable as upgrade)
• Power rating: 0.125W minimum (0.25W acceptable as upgrade)
• Temperature coefficient: ±50ppm/°C or better (±25ppm/°C or ±10ppm/°C acceptable as upgrade)
• Certifications and features: Additional certifications (AEC-Q200, Anti-Sulfur) do not prevent substitution

All identified substitute parts maintain the 0805 package footprint, 124 kOhms resistance, thin film construction, and -55°C to 155°C operating range. Substitutes with improved tolerance (±0.1%), lower temperature coefficient, or higher power ratings represent performance upgrades while maintaining full electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Direct Upgrade (Same Manufacturer): RT0805BRD07124KL from YAGEO provides improved tolerance (±0.1% vs ±0.25%) and lower temperature coefficient (±25ppm/°C vs ±50ppm/°C) while maintaining identical power rating, package, and physical dimensions. This part is recommended for applications requiring tighter tolerance control.

Higher Power Rating Option: 2176094-4 from TE Connectivity (Holsworthy series) doubles the power rating to 0.25W while maintaining ±0.1% tolerance and ±25ppm/°C temperature coefficient. Physical height increases to 0.65mm maximum. This part is suitable for applications with higher power dissipation requirements.

Automotive-Qualified Options: ERA-6AEB1243V (Panasonic) and RG2012N-1243-B-T5 / RG2012P-1243-B-T5 (Susumu) carry AEC-Q200 automotive qualification. These parts are suitable for automotive and high-reliability applications. RG2012N-1243-B-T5 offers the lowest temperature coefficient (±10ppm/°C) and includes anti-sulfur protection. All automotive-qualified options maintain 0.125W power rating and 0805 package compatibility.

All substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard PCB assembly processes.

Frequently Asked Questions (FAQ)

Q: Can RT0805BRD07124KL replace RT0805CRE07124KL in my design? A: Yes. Both parts share identical resistance (124 kOhms), package (0805), power rating (0.125W), and operating temperature range (-55°C to 155°C). RT0805BRD07124KL provides improved tolerance (±0.1% vs ±0.25%) and lower temperature coefficient (±25ppm/°C vs ±50ppm/°C), making it a direct upgrade with no design modifications required.

Q: What is the difference between RG2012N-1243-B-T5 and RG2012P-1243-B-T5? A: Both parts are manufactured by Susumu in the 0805 package with 124 kOhms resistance and ±0.1% tolerance. The primary difference is temperature coefficient: RG2012N-1243-B-T5 has ±10ppm/°C while RG2012P-1243-B-T5 has ±25ppm/°C. Both include anti-sulfur protection and AEC-Q200 automotive qualification. Selection depends on temperature stability requirements.

Q: Can I use 2176094-4 as a substitute if my circuit board layout is already fixed? A: Physical compatibility must be verified. While 2176094-4 maintains the 0805 package footprint, its maximum seated height is 0.65mm compared to 0.60mm for the original part. Verify clearance above the component before substitution. The doubled power rating (0.25W vs 0.125W) does not affect electrical compatibility.

Q: Are the Susumu RG2012 parts suitable for automotive applications? A: Yes. Both RG2012N-1243-B-T5 and RG2012P-1243-B-T5 carry AEC-Q200 automotive qualification and anti-sulfur protection. These parts are approved for automotive and high-reliability applications requiring enhanced environmental performance.

Q: What does MSL 1 (Unlimited) mean for moisture sensitivity? A: MSL 1 indicates the lowest moisture sensitivity level. These components can be stored indefinitely without moisture baking requirements and are compatible with standard PCB assembly processes without special handling.

Q: Do all substitute parts have the same footprint? A: Yes. All substitute parts use the 0805 (2012 Metric) package with identical land pattern dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm). Physical height varies slightly (0.50mm to 0.65mm maximum seated height), but this does not affect PCB footprint compatibility.
