Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RT1206DRE07105RL are qualified based on the following criteria:

Core Electrical Compatibility:

• Identical resistance value: 105 Ohms
• Equal or superior tolerance: ±0.5% or better
• Equal or greater power rating: 0.25W minimum
• Thin film composition maintained

Mechanical Compatibility:

• Package type: 1206 (3216 Metric)
• Operating temperature range: -55°C to 155°C minimum
• Two terminations (standard SMD configuration)

Compliance & Certification:

• ROHS3 compliance required
• MSL rating 1 or equivalent
• REACH unaffected status

The identified substitutes meet or exceed these parameters while offering enhanced specifications such as improved tolerance (±0.1%) and automotive AEC-Q200 qualification where applicable.

Parameter Comparison

Engineering Selection Recommendations

RT1206DRE07105RL (YAGEO): Primary selection for general-purpose applications requiring standard tolerance (±0.5%) and cost-effective sourcing. Active product status with established supply chain.

ERA-8AEB1050V (Panasonic): Suitable for applications requiring improved tolerance specification (±0.1%) and automotive-grade reliability. AEC-Q200 qualification provides enhanced quality assurance for automotive and industrial environments. Lower temperature coefficient (±25ppm/°C) improves stability across temperature extremes.

RG3216P-1050-B-T1 (Susumu): Recommended for harsh environment applications requiring anti-sulfur protection combined with automotive AEC-Q200 qualification. Lowest seated height (0.020" / 0.50mm) accommodates space-constrained PCB layouts. Superior temperature coefficient performance matches Panasonic equivalent.

Frequently Asked Questions (FAQ)

Q: Can ERA-8AEB1050V or RG3216P-1050-B-T1 be used as direct drop-in replacements for RT1206DRE07105RL?

A: Yes. All three parts share identical resistance value (105 Ohms), power rating (0.25W), package type (1206), and operating temperature range (-55°C to 155°C). The substitute parts offer equal or superior tolerance and temperature coefficient specifications, ensuring functional compatibility in existing designs.

Q: What is the significance of the ±0.1% tolerance in substitute parts compared to the ±0.5% tolerance of the main part?

A: Tolerance defines the acceptable deviation from the nominal resistance value. The ±0.1% tolerance in ERA-8AEB1050V and RG3216P-1050-B-T1 provides tighter resistance accuracy, reducing circuit performance variation. This is beneficial in precision analog circuits, measurement applications, and systems with tight gain or frequency specifications.

Q: Are the substitute parts suitable for automotive applications?

A: ERA-8AEB1050V and RG3216P-1050-B-T1 carry AEC-Q200 automotive qualification, meeting automotive industry reliability standards. The RT1206DRE07105RL does not specify automotive qualification. Selection depends on application requirements and end-use environment.

Q: What is the advantage of anti-sulfur protection in RG3216P-1050-B-T1?

A: Anti-sulfur protection prevents degradation of component performance in environments with hydrogen sulfide exposure or high-sulfur atmospheric conditions. This feature is relevant for industrial, marine, or specialized manufacturing environments where sulfur contamination is a concern.

Q: Do all three parts have identical physical dimensions?

A: Core package dimensions are equivalent (1206 / 3216 Metric). Minor variations exist in seated height: RT1206DRE07105RL (0.026" / 0.65mm), ERA-8AEB1050V (0.028" / 0.70mm), and RG3216P-1050-B-T1 (0.020" / 0.50mm). These differences are within standard PCB assembly tolerances and do not affect interchangeability in typical applications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. RT1206DRE07105RL, ERA-8AEB1050V, and RG3216P-1050-B-T1 are all ROHS3 compliant with MSL rating 1 (Unlimited) and REACH unaffected status, meeting environmental and regulatory requirements for global markets.
