Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CPF1206B110RE1 are qualified based on the following critical parameters that determine functional and mechanical compatibility:

Electrical Parameters:

• Resistance value: 110 Ohms (exact match required)
• Tolerance: ±0.1% (exact match required)
• Temperature coefficient: ±25ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)
• Composition: Thin Film (exact match required)

Mechanical Parameters:

• Package / Case: 1206 (3216 Metric) (exact match required)
• Number of terminations: 2 (exact match required)

Compliance Parameters:

• RoHS Status: ROHS3 Compliant (minimum requirement)
• Moisture Sensitivity Level: 1 (Unlimited) (minimum requirement)

The identified substitute parts meet all critical electrical and mechanical parameters. Power rating variations are permitted when substitute parts exceed the original specification, as this represents an upgrade in thermal capability without affecting circuit performance in applications designed for the original 0.125W rating.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts ERA-8AEB111V and RT1206BRD07110RL are direct functional equivalents to the CPF1206B110RE1 for applications requiring 110 Ohms ±0.1% thin film resistors in the 1206 package format.

ERA-8AEB111V (Panasonic Electronic Components): This substitute carries AEC-Q200 automotive qualification, indicating compliance with automotive-grade reliability standards. The part is rated for 0.25W (1/4W) power dissipation, providing increased thermal margin compared to the original specification. REACH status is listed as Unaffected. This option is suitable for applications requiring automotive-grade components or where enhanced thermal performance is beneficial.

RT1206BRD07110RL (YAGEO): This substitute is rated for 0.25W (1/4W) power dissipation and maintains all electrical specifications identical to the main part. REACH status is listed as Unaffected. This option provides a cost-effective alternative with equivalent performance characteristics and higher power rating.

Both substitutes maintain ROHS3 compliance, unlimited moisture sensitivity level (MSL 1), and identical electrical parameters including resistance, tolerance, temperature coefficient, and operating temperature range. Selection between substitutes depends on supply availability, cost considerations, and any specific automotive qualification requirements of the end application.

Frequently Asked Questions (FAQ)

Q: Can ERA-8AEB111V be used as a direct replacement for CPF1206B110RE1?

A: Yes. Both parts share identical electrical specifications (110 Ohms ±0.1%, ±25ppm/°C temperature coefficient, -55°C to 155°C operating range) and mechanical compatibility (1206 package, 2 terminations). The ERA-8AEB111V features a higher power rating (0.25W vs. 0.125W), which represents an upgrade in thermal capability without affecting circuit performance.

Q: Can RT1206BRD07110RL be used as a direct replacement for CPF1206B110RE1?

A: Yes. Both parts share identical electrical specifications (110 Ohms ±0.1%, ±25ppm/°C temperature coefficient, -55°C to 155°C operating range) and mechanical compatibility (1206 package, 2 terminations). The RT1206BRD07110RL features a higher power rating (0.25W vs. 0.125W), which represents an upgrade in thermal capability without affecting circuit performance.

Q: What is the significance of the 1206 package designation?

A: The 1206 package (3216 Metric) is a standardized surface mount resistor format with dimensions of approximately 3.0mm x 1.5mm. All three parts in this comparison use this identical package, ensuring mechanical compatibility on printed circuit boards without requiring layout modifications.

Q: Are there any compliance differences between the main part and substitutes?

A: All three parts are ROHS3 compliant with unlimited moisture sensitivity level (MSL 1). The ERA-8AEB111V carries additional AEC-Q200 automotive qualification. All parts have ECCN classification of EAR99 and identical HTSUS codes (8533.21.0030).

Q: Does the higher power rating of the substitute parts affect circuit operation?

A: No. The substitute parts are rated for higher power dissipation (0.25W vs. 0.125W) but maintain identical resistance, tolerance, and temperature coefficient specifications. In applications designed for the original 0.125W rating, the higher power rating provides additional thermal margin without altering electrical performance.

Q: What is the tolerance specification and why is it important?

A: All three parts are specified at ±0.1% tolerance, indicating precision thin film resistor construction. This tight tolerance is critical for applications requiring accurate resistance values, such as precision measurement circuits, analog signal conditioning, and calibration networks.

Q: Are the physical dimensions identical across all three parts?

A: The parts share the same 1206 package designation but have minor dimensional variations. CPF1206B110RE1 and RT1206BRD07110RL both have a maximum seated height of 0.026" (0.65mm), while ERA-8AEB111V has a maximum seated height of 0.028" (0.70mm). These variations are within standard 1206 package tolerances and do not affect PCB assembly compatibility.
