Engineering Selection Recommendations

Direct Replacement (Same Electrical Specifications):

The TE Connectivity CPF-A-0805B82KE and CPF-A-0805B82KE1 are direct replacements for the obsolete 1614953-1. Both maintain identical electrical parameters (82 kΩ, ±0.1%, 0.1W, ±25ppm/°C) and are available in active product status from the original manufacturer. These parts are recommended for applications requiring exact specification matching without additional automotive or enhanced environmental requirements.

Upgraded Substitutes with Enhanced Features:

Panasonic ERA-6A series resistors (ERA-6AEB823V, ERA-6APB823V, ERA-6ARB823V, ERA-6ARW823V) provide active product status with Automotive AEC-Q200 certification. The ERA-6ARB823V and ERA-6ARW823V offer improved temperature coefficient stability (±10ppm/°C) compared to the original ±25ppm/°C specification. The ERA-6ARW823V provides enhanced tolerance (±0.05%) and is suitable for precision applications. All ERA-6A variants feature higher power ratings (0.125W) and full operating temperature range compatibility (-55°C ~ 155°C).

Susumu RG2012 series resistors (RG2012N-823-B-T5, RG2012N-823-W-T5, RG2012P-823-B-T5) provide Automotive AEC-Q200 certification with anti-sulfur composition. The RG2012N-823-B-T5 and RG2012P-823-B-T5 maintain ±0.1% tolerance with improved temperature coefficient (±10ppm/°C and ±25ppm/°C respectively). The RG2012N-823-W-T5 offers ±0.05% tolerance with ±10ppm/°C temperature coefficient for precision applications.

Vishay Beyschlag MCU08050D8202BP500 provides active product status with anti-sulfur composition and 0.125W power rating. Operating temperature range extends to -55°C ~ 125°C, which is acceptable for most applications within the original -55°C ~ 155°C specification.

Selection Criteria:

For standard industrial applications: CPF-A-0805B82KE or CPF-A-0805B82KE1
For automotive applications: ERA-6AEB823V, ERA-6APB823V, ERA-6ARB823V, RG2012N-823-B-T5, or RG2012P-823-B-T5
For precision applications: ERA-6ARW823V or RG2012N-823-W-T5
For improved temperature stability: ERA-6ARB823V or RG2012N-823-B-T5 (±10ppm/°C)

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with higher power rating (0.125W instead of 0.1W)?

A: Yes. A higher power rating indicates greater power dissipation capability. Substituting a 0.125W (1/8W) rated resistor for a 0.1W (1/10W) rated component is electrically compatible and provides additional thermal margin. The physical dimensions remain identical in the 0805 package.

Q: What is the difference between ±0.1% and ±0.05% tolerance?

A: Tolerance specifies the maximum deviation from the nominal resistance value. A ±0.05% tolerance resistor has tighter manufacturing control and will remain closer to 82 kOhms than a ±0.1% part. The ±0.05% tolerance is a superset of ±0.1% tolerance and is suitable for applications requiring higher precision.

Q: Are all substitute parts RoHS3 compliant?

A: All substitute parts listed are RoHS3 compliant. The original 1614953-1 does not specify RoHS status. RoHS3 compliance ensures the component meets restrictions on hazardous substances in electrical and electronic equipment.

Q: What does AEC-Q200 certification mean?

A: AEC-Q200 is an automotive qualification standard for passive components. Parts bearing this certification have undergone rigorous testing for automotive applications including temperature cycling, humidity resistance, and reliability. AEC-Q200 certification is not required for the original 1614953-1 but is available on several substitute options for enhanced reliability in automotive environments.

Q: Can I substitute the TE Connectivity CPF-A series for the original 1614953-1?

A: Yes. The CPF-A-0805B82KE and CPF-A-0805B82KE1 are direct electrical and mechanical equivalents. Both are manufactured by TE Connectivity and maintain all critical parameters. The CPF-A series offers active product status and enhanced features including anti-sulfur and moisture-resistant composition.

Q: What is the significance of temperature coefficient (ppm/°C)?

A: Temperature coefficient indicates how much the resistance value changes with temperature. A lower temperature coefficient (±10ppm/°C) indicates better stability across the operating temperature range compared to ±25ppm/°C. For applications sensitive to resistance drift over temperature, parts with ±10ppm/°C or ±15ppm/°C are preferred.

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

A: All parts listed use the 0805 (2012 Metric) package with identical length (0.079" / 2.00mm) and width (0.049" / 1.25mm). Height varies slightly between manufacturers (0.020" to 0.026" seated height), but this variation is within standard PCB assembly tolerances and does not affect compatibility.

Q: Which substitute part offers the best overall performance?

A: Selection depends on application requirements. For automotive applications requiring AEC-Q200 certification with improved temperature stability, the ERA-6ARB823V or RG2012N-823-B-T5 (both ±10ppm/°C) are optimal. For precision applications, the ERA-6ARW823V or RG2012N-823-W-T5 (both ±0.05% tolerance, ±10ppm/°C) provide superior performance.

Q: Is the operating temperature range difference between -55°C ~ 155°C and -55°C ~ 125°C significant?

A: The MCU08050D8202BP500 operates to 125°C maximum, while the original and most substitutes operate to 155°C. This difference is significant only if the application requires sustained operation above 125°C. For most industrial and automotive applications operating within -55°C ~ 125°C, this part is fully compatible.
