Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT0805DRE07124KL is determined by the following criteria:

Primary Matching Parameters:

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

Secondary Compatibility Parameters:

• Tolerance: ±0.5% 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)
• RoHS and MSL compliance: ROHS3 and MSL 1 required

All identified substitutes meet or exceed the primary matching parameters. Upgrades offer improved tolerance, lower temperature coefficient, or higher power ratings while maintaining full mechanical and electrical compatibility.

Parameter Comparison

Engineering Selection Recommendations

YAGEO RT0805BRD07124KL — Direct upgrade within the same manufacturer series. Offers improved tolerance (±0.1% vs ±0.5%) and lower temperature coefficient (±25ppm/°C vs ±50ppm/°C) while maintaining identical power rating and package dimensions. Recommended for applications requiring tighter tolerance specifications without changing supply chain.

TE Connectivity 2176094-4 — Higher power rating (0.25W vs 0.125W) with improved tolerance and temperature coefficient. Seated height increases by 0.002" (0.05mm). Suitable for applications with elevated thermal requirements or where additional power margin is beneficial.

Panasonic ERA-6AEB1243V — Automotive-grade component with AEC-Q200 certification. Identical electrical specifications to RT0805BRD07124KL with automotive qualification. Recommended for automotive and high-reliability applications requiring AEC-Q200 compliance.

Susumu RG2012N-1243-B-T5 — Premium option with lowest temperature coefficient (±10ppm/°C), anti-sulfur coating, and AEC-Q200 certification. Seated height reduced to 0.020" (0.50mm). Recommended for precision applications and harsh environments requiring superior stability and corrosion resistance.

Susumu RG2012P-1243-B-T5 — Anti-sulfur coating and AEC-Q200 certification with standard temperature coefficient (±25ppm/°C). Seated height reduced to 0.020" (0.50mm). Suitable for automotive and corrosive environment applications where anti-sulfur protection is required.

Frequently Asked Questions (FAQ)

Q: Can RT0805BRD07124KL directly replace RT0805DRE07124KL?

A: Yes. Both components share identical package dimensions (0805), resistance value (124 kOhms), power rating (0.125W), and operating temperature range (-55°C ~ 155°C). RT0805BRD07124KL offers improved tolerance (±0.1% vs ±0.5%) and lower temperature coefficient (±25ppm/°C vs ±50ppm/°C), making it a direct upgrade with no layout or thermal modifications required.

Q: What is the difference between Susumu RG2012N-1243-B-T5 and RG2012P-1243-B-T5?

A: Both components are identical except for temperature coefficient. RG2012N-1243-B-T5 has ±10ppm/°C while RG2012P-1243-B-T5 has ±25ppm/°C. Both include anti-sulfur coating and AEC-Q200 certification. Selection depends on precision requirements; RG2012N-1243-B-T5 is preferred for applications requiring superior temperature stability.

Q: Is TE Connectivity 2176094-4 compatible with the original design?

A: Mechanically and electrically compatible. The component has higher power rating (0.25W vs 0.125W) and seated height increases by 0.002" (0.05mm). Verify PCB clearance and thermal design accommodate the higher power rating. Tolerance and temperature coefficient are improved (±0.1%, ±25ppm/°C).

Q: Which substitute is suitable for automotive applications?

A: ERA-6AEB1243V, RG2012N-1243-B-T5, and RG2012P-1243-B-T5 all carry AEC-Q200 certification. RG2012N-1243-B-T5 offers the lowest temperature coefficient (±10ppm/°C) and anti-sulfur protection. RG2012P-1243-B-T5 provides anti-sulfur protection with standard temperature coefficient. ERA-6AEB1243V is the baseline automotive option without anti-sulfur coating.

Q: Does package size change affect PCB layout?

A: All substitutes use 0805 (2012 Metric) package with identical length (0.079") and width (0.049"). Seated height varies: original and YAGEO/Panasonic options are 0.024" (0.60mm); TE Connectivity is 0.026" (0.65mm); Susumu options are 0.020" (0.50mm). Verify clearance for components or conformal coating in height-constrained designs.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All listed substitutes are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level, matching the original component's environmental compliance profile.
