ACPP0805 820R B Equivalent & Substitute Parts

Part Overview

The ACPP0805 820R B is a thin film chip resistor manufactured by Ohmite in the 0805 (2012 Metric) package. This 820 Ohm ±0.1% resistor rated at 0.1W is designed for precision applications requiring tight tolerance and stable performance across the -55°C to 155°C operating range. The part is active and in production, with ROHS3 compliance and MSL 1 rating. Equivalent and substitute parts are identified for applications requiring alternative sourcing, higher power ratings, automotive qualification, or enhanced environmental protection.

Substitute Part Grouping Explanation

Substitution is determined by matching the following critical parameters: resistance value (820 Ohms), tolerance (±0.1%), package format (0805), composition (thin film), temperature coefficient (±25ppm/°C), and operating temperature range (-55°C to 155°C). Parts are grouped into two categories:

Direct Equivalents maintain the original 0.1W power rating and are suitable for one-to-one replacement without circuit redesign.

Upgrade Substitutes feature higher power ratings (0.125W or 0.26W), automotive AEC-Q200 qualification, anti-sulfur properties, or enhanced moisture resistance. These parts are electrically compatible and physically interchangeable within the 0805 package footprint, with the same resistance, tolerance, and temperature characteristics. Higher power ratings provide additional thermal margin and reliability in demanding applications.

Engineering Selection Recommendations

CPF0805B820RE1 (TE Connectivity) is the direct equivalent for applications requiring identical electrical and thermal specifications. This part maintains the 0.1W power rating and is suitable for standard industrial applications with no automotive or enhanced environmental requirements.

ERA-6AEB821V (Panasonic) is recommended for automotive applications requiring AEC-Q200 qualification. The increased 0.125W power rating provides thermal margin while maintaining the same footprint and electrical characteristics.

RG2012P-821-B-T5 (Susumu) combines AEC-Q200 automotive qualification with anti-sulfur protection, making it suitable for harsh automotive environments and applications exposed to corrosive atmospheres.

RT0805BRD07820RL (YAGEO) offers a 0.125W upgrade with standard industrial compliance, providing increased power handling without automotive-specific requirements.

TNPW0805820RBEEA (Vishay Dale) provides the highest power rating at 0.26W with extended operating temperature to 175°C, combined with AEC-Q200 qualification, anti-sulfur protection, and moisture resistance. This part is suitable for high-reliability applications and environments with elevated temperature or corrosive conditions.

Frequently Asked Questions (FAQ)

Q: Can I substitute the ACPP0805 820R B with a higher power-rated part? A: Yes. All listed upgrade substitutes maintain the same 820 Ohm resistance, ±0.1% tolerance, ±25ppm/°C temperature coefficient, and 0805 package format. Higher power ratings (0.125W or 0.26W) are electrically compatible and provide additional thermal margin without affecting circuit performance.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts meet ROHS3 compliance requirements and are suitable for applications with environmental regulations.

Q: What is the difference between direct equivalents and upgrade substitutes? A: Direct equivalents (CPF0805B820RE1) maintain the original 0.1W power rating for one-to-one replacement. Upgrade substitutes feature higher power ratings and may include automotive AEC-Q200 qualification, anti-sulfur properties, or extended temperature ranges for enhanced reliability in demanding applications.

Q: Which substitute should I use for automotive applications? A: ERA-6AEB821V, RG2012P-821-B-T5, and TNPW0805820RBEEA all carry AEC-Q200 automotive qualification. RG2012P-821-B-T5 and TNPW0805820RBEEA additionally include anti-sulfur protection for corrosive environments.

Q: Are all parts physically interchangeable in the 0805 package? A: Yes. All substitute parts use the 0805 (2012 Metric) package with identical footprint dimensions (0.079" L x 0.049" W). Height variations are minimal (0.020" to 0.026" seated height) and do not affect PCB assembly compatibility.

Q: What is the maximum operating temperature for each part? A: ACPP0805 820R B, CPF0805B820RE1, ERA-6AEB821V, RG2012P-821-B-T5, and RT0805BRD07820RL operate to 155°C. TNPW0805820RBEEA extends to 175°C for high-temperature applications.

Q: Do all parts have MSL 1 rating? A: Yes. All listed parts have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity concerns for storage and handling.
