RT0603BRE07124RL Equivalent & Substitute Parts

Part Overview

The RT0603BRE07124RL is a 124 Ohms ±0.1% thin film chip resistor in 0603 (1608 Metric) package rated at 0.1W (1/10W) power dissipation. Manufactured by YAGEO under the RT series, this component is actively produced and widely used in precision analog circuits requiring tight tolerance specifications. Substitute parts become necessary due to inventory constraints, supply chain disruptions, or specific application requirements such as automotive qualification or enhanced temperature stability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT0603BRE07124RL is determined by the following mandatory parameters:

• Resistance value: 124 Ohms (exact match required)
• Tolerance: ±0.1% (exact match required)
• Package: 0603 (1608 Metric) (exact match required)
• Composition: Thin Film (exact match required)
• Operating temperature range: -55°C to 155°C minimum (equal or wider range acceptable)
• Moisture sensitivity: MSL 1 or better (lower MSL acceptable)
• RoHS compliance: ROHS3 or equivalent (compliance required)

The substitute parts listed below meet all mandatory substitution criteria. Variations in temperature coefficient, power rating, and manufacturer-specific features are noted but do not preclude substitution when the above parameters are satisfied.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active product status and full RoHS3 compliance, ensuring continued availability and regulatory conformance.

RT0603BRD07124RL represents a direct equivalent from YAGEO with identical electrical specifications and packaging. The primary distinction is an improved temperature coefficient of ±25ppm/°C compared to the main part's ±50ppm/°C, providing enhanced temperature stability without any trade-offs in other parameters.

ERA-3AEB1240V offers automotive-grade qualification under AEC-Q200 standard with equivalent electrical performance. This part is suitable for applications requiring automotive-level reliability and traceability. Temperature coefficient matches the RT0603BRD07124RL at ±25ppm/°C.

RP73PF1J124RBTDF from TE Connectivity provides a higher power rating of 0.167W (1/6W) within the same 0603 package footprint. This part accommodates applications with increased power dissipation requirements while maintaining all other critical parameters. Temperature coefficient is ±25ppm/°C.

Frequently Asked Questions (FAQ)

Q: Can RT0603BRD07124RL be used as a direct replacement for RT0603BRE07124RL?

A: Yes. Both parts share identical resistance (124 Ohms), tolerance (±0.1%), power rating (0.1W), package (0603), composition (thin film), and operating temperature range (-55°C to 155°C). The RT0603BRD07124RL features an improved temperature coefficient of ±25ppm/°C versus ±50ppm/°C on the main part, making it a functionally superior substitute.

Q: What is the difference between the main part and ERA-3AEB1240V?

A: ERA-3AEB1240V is functionally equivalent with identical electrical specifications. The key distinction is AEC-Q200 automotive qualification, which provides enhanced reliability documentation and traceability for automotive applications. Temperature coefficient is ±25ppm/°C.

Q: Can RP73PF1J124RBTDF replace RT0603BRE07124RL in all applications?

A: RP73PF1J124RBTDF is electrically and mechanically compatible. The primary difference is a higher power rating of 0.167W (1/6W) compared to 0.1W (1/10W). This higher rating does not create incompatibility; it simply provides additional thermal margin. Dimensional differences are minimal (1.55mm vs 1.60mm length), with no impact on standard PCB layouts.

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

A: Yes. All substitute parts are supplied in Tape & Reel (TR) packaging, matching the main part's delivery format. MSL rating is MSL 1 (Unlimited) for all parts, indicating no moisture sensitivity constraints during storage or handling.

Q: Which substitute part offers the best temperature stability?

A: RT0603BRD07124RL, ERA-3AEB1240V, and RP73PF1J124RBTDF all feature a temperature coefficient of ±25ppm/°C, which is superior to the main part's ±50ppm/°C. Selection between these three should be based on availability, automotive requirements, or power dissipation needs rather than temperature stability.
