RT0805BRE07124RL Equivalent & Substitute Parts

Part Overview

The RT0805BRE07124RL is a 124 Ohms ±0.1% thin film chip resistor in 0805 (2012 Metric) package manufactured by YAGEO. This precision resistor operates at 0.125W (1/8W) power rating with a temperature coefficient of ±50ppm/°C and is rated for -55°C to 155°C operating temperature range. The part is ROHS3 compliant and carries MSL 1 (Unlimited) moisture sensitivity rating. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained within the allowed parameter tolerances for this resistor category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT0805BRE07124RL is determined by the following critical parameters:

• Resistance value: 124 Ohms (exact match required)
• Tolerance: ±0.1% (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 (equal or higher compliance acceptable)
• MSL rating: 1 (Unlimited) (equal or lower MSL acceptable)

Substitute parts are grouped into two categories: direct equivalents with identical power ratings and upgraded variants with enhanced specifications or automotive certifications.

Parameter Comparison

Engineering Selection Recommendations

RT0805BRD07124RL (YAGEO) — Direct equivalent with improved temperature coefficient (±25ppm/°C vs ±50ppm/°C). Maintains identical power rating, package, and compliance status. Higher inventory availability (9320 pcs vs 689 pcs).

3-2176091-3 (TE Connectivity) — Direct equivalent with higher power rating (0.25W vs 0.125W). Identical tolerance and temperature range. Suitable for applications requiring additional thermal margin. REACH status listed as Vendor Undefined.

ERA-6AEB1240V (Panasonic) — Direct equivalent with AEC-Q200 automotive certification. Improved temperature coefficient (±25ppm/°C). Suitable for automotive and high-reliability applications. Highest inventory availability (17568 pcs).

RG2012P-1240-B-T5 (Susumi) — Direct equivalent with AEC-Q200 automotive certification and anti-sulfur feature. Improved temperature coefficient (±25ppm/°C). Lowest seated height (0.020" vs 0.024"). Suitable for automotive and corrosive environment applications.

All substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) rating. Selection should be based on application requirements for automotive certification, thermal performance, and environmental resistance.

Frequently Asked Questions (FAQ)

Q: Can RT0805BRD07124RL replace RT0805BRE07124RL directly?

A: Yes. Both parts share identical resistance (124 Ohms), tolerance (±0.1%), power rating (0.125W), package (0805), and operating temperature range (-55°C to 155°C). RT0805BRD07124RL offers improved temperature coefficient (±25ppm/°C vs ±50ppm/°C).

Q: Is 3-2176091-3 compatible as a substitute?

A: Yes, with consideration for power rating. The TE Connectivity part maintains all critical electrical parameters but provides higher power rating (0.25W vs 0.125W). Physical dimensions remain compatible with 0805 package footprint.

Q: When should ERA-6AEB1240V or RG2012P-1240-B-T5 be selected?

A: These Panasonic and Susumi parts are selected when automotive-grade reliability (AEC-Q200) is required. Both offer improved temperature coefficient (±25ppm/°C) and are suitable for automotive and harsh environment applications.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, matching the original RT0805BRE07124RL specifications.

Q: What is the difference between ±50ppm/°C and ±25ppm/°C temperature coefficient?

A: Temperature coefficient defines resistance change per degree Celsius. ±25ppm/°C represents tighter temperature stability than ±50ppm/°C. Substitute parts with ±25ppm/°C offer improved performance in temperature-sensitive applications.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes. All substitute parts use identical 0805 (2012 Metric) package with compatible footprints, solder pad configurations, and mechanical dimensions. No PCB redesign is required.
