Substitute Part Grouping Explanation

Substitution eligibility for the RT1206BRE07124RL is determined by strict equivalence across the following critical parameters:

• Resistance value: 124 Ohms
• Tolerance: ±0.1%
• Power rating: 0.25W (1/4W)
• Package format: 1206 (3216 Metric)
• Composition: Thin Film
• Operating temperature range: -55°C ~ 155°C
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

All identified substitute parts meet these core requirements. Variations in temperature coefficient and dimensional tolerances do not affect functional substitutability within standard circuit applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts are actively produced and ROHS3 compliant, meeting standard industrial and commercial requirements. Selection between RT1206BRE07124RL and RT1206BRD07124RL depends on inventory availability and temperature coefficient tolerance requirements; both are YAGEO RT series components with identical core specifications.

ERA-8AEB1240V is suitable for applications requiring automotive-grade qualification (AEC-Q200). This part carries enhanced reliability certification and is appropriate for automotive and mission-critical applications where AEC-Q200 compliance is specified.

Temperature coefficient differences (±50ppm/°C versus ±25ppm/°C) are secondary selection criteria and do not affect substitutability in general-purpose circuit applications operating within the specified temperature range.

Frequently Asked Questions (FAQ)

Q: Can RT1206BRD07124RL replace RT1206BRE07124RL in any circuit?

A: Yes. Both parts are electrically and mechanically equivalent. They share identical resistance, tolerance, power rating, package format, and operating temperature range. The lower temperature coefficient of RT1206BRD07124RL (±25ppm/°C versus ±50ppm/°C) represents an improvement in thermal stability.

Q: Is ERA-8AEB1240V suitable for non-automotive applications?

A: Yes. ERA-8AEB1240V meets all core electrical and mechanical requirements for direct substitution. The AEC-Q200 automotive qualification is an additional certification that does not restrict use in standard industrial or commercial circuits.

Q: Are there physical mounting differences between these parts?

A: All three parts use the 1206 (3216 Metric) package format. Dimensional variations (RT1206BRE07124RL: 3.10mm × 1.60mm; ERA-8AEB1240V: 3.20mm × 1.60mm) are within standard PCB pad tolerance and do not affect mounting compatibility.

Q: What is the significance of the temperature coefficient difference?

A: Temperature coefficient indicates resistance value drift over temperature. RT1206BRE07124RL exhibits ±50ppm/°C drift, while RT1206BRD07124RL and ERA-8AEB1240V exhibit ±25ppm/°C drift. For circuits with tight tolerance requirements across temperature extremes, the lower coefficient provides improved stability.

Q: Can these parts be used interchangeably in production?

A: Yes, provided circuit design does not specify a particular manufacturer or series. All three parts meet the same electrical and mechanical requirements. Verify PCB layout compatibility with dimensional specifications before production transition.
