Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT1206BRE07523KL is determined by the following critical parameters:

• Resistance value: 523 kOhms (exact match required)
• Tolerance: ±0.1% (precision specification)
• Power rating: 0.25W minimum
• Package: 1206 (3216 Metric) form factor
• Composition: Thin film construction
• Operating temperature range: -55°C to 155°C minimum coverage
• RoHS3 compliance and MSL 1 rating

The ERA-8AEB5233V from Panasonic Electronic Components meets all substitution criteria. This part maintains identical electrical specifications while offering enhanced automotive-grade qualification (AEC-Q200) and improved temperature coefficient performance (±25ppm/°C versus ±50ppm/°C).

Parameter Comparison

Engineering Selection Recommendations

Both the RT1206BRE07523KL and ERA-8AEB5233V are active production parts with ROHS3 compliance and identical core electrical specifications. Selection between these parts depends on application requirements:

The RT1206BRE07523KL is suitable for general-purpose industrial and consumer applications where standard thin film precision and temperature stability are sufficient.

The ERA-8AEB5233V is the preferred selection for automotive applications, harsh environments, or designs requiring enhanced reliability. The AEC-Q200 automotive qualification and superior temperature coefficient (±25ppm/°C) provide tighter performance margins across extended operating ranges.

Both parts are pin-compatible and footprint-compatible in 1206 package designs. Physical dimensions show minor variation (length 3.10mm versus 3.20mm, height 0.65mm versus 0.70mm) that remain within standard PCB assembly tolerances.

Frequently Asked Questions (FAQ)

Q: Can ERA-8AEB5233V directly replace RT1206BRE07523KL in existing designs?

A: Yes. Both parts share identical electrical specifications (523 kOhms ±0.1%, 0.25W), package format (1206), and operating temperature range (-55°C to 155°C). Physical dimensions are within standard assembly tolerances. No circuit modifications are required.

Q: What is the significance of the ±25ppm/°C temperature coefficient in ERA-8AEB5233V?

A: The ERA-8AEB5233V exhibits tighter temperature stability (±25ppm/°C) compared to the RT1206BRE07523KL (±50ppm/°C). This means resistance value changes more slowly with temperature variations, beneficial for precision analog circuits and automotive applications subject to wider thermal cycling.

Q: Does AEC-Q200 qualification affect compatibility?

A: No. AEC-Q200 is an automotive reliability standard that qualifies the ERA-8AEB5233V for automotive use. It does not restrict use in non-automotive applications. The qualification indicates enhanced testing and reliability margins, making it suitable for any application requiring higher reliability standards.

Q: Are there package dimension differences that affect PCB assembly?

A: Minor differences exist: RT1206BRE07523KL measures 3.10mm × 1.60mm × 0.65mm (max height), while ERA-8AEB5233V measures 3.20mm × 1.60mm × 0.70mm (max height). These variations fall within standard 1206 package tolerances and do not require PCB footprint modifications.

Q: What is MSL 1 rating and why is it important?

A: MSL (Moisture Sensitivity Level) 1 indicates unlimited shelf life without moisture baking requirements. Both parts carry MSL 1, meaning they can be stored and handled under standard conditions without special moisture control procedures, simplifying inventory and assembly logistics.
