Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Direct Equivalents maintain identical electrical specifications: 82 Ohms resistance, ±0.1% tolerance, 0.1W power rating, thin film composition, ±25ppm/°C temperature coefficient, and -55°C to 155°C operating range. These parts are interchangeable without circuit redesign.

Upgrade Substitutes provide enhanced specifications while maintaining core electrical parameters. These parts increase power rating from 0.1W to 0.125W (1/8W), incorporate automotive AEC-Q200 certification, or add anti-sulfur features. Upgrade substitutes are compatible with designs specified for the ACPP0805 82R B and offer improved reliability margins or environmental performance.

All substitute parts share the identical 0805 (2012 Metric) package footprint, dimensional specifications (0.079" L x 0.049" W), two terminations, RoHS3 compliance, and MSL 1 rating.

Engineering Selection Recommendations

CPF0805B82RE1 (TE Connectivity) serves as the direct equivalent substitute for the ACPP0805 82R B. Both components maintain identical electrical and mechanical specifications with 0.1W power rating and standard thin film construction. Selection of this part is appropriate when Ohmite supply is unavailable and equivalent performance is required.

ERA-6AEB820V (Panasonic) and RG2012P-820-B-T5 (Susumi) are upgrade substitutes offering 0.125W power rating with AEC-Q200 automotive qualification. These parts are suitable for applications requiring automotive-grade reliability or designs where enhanced power margin is beneficial. The RG2012P-820-B-T5 additionally incorporates anti-sulfur features for enhanced environmental resistance.

RT0805BRD0782RL (YAGEO) provides 0.125W power rating without automotive certification. This part is appropriate for non-automotive applications where increased power margin is desired without the cost premium of AEC-Q200 qualification.

All substitute parts maintain RoHS3 compliance and MSL 1 rating consistent with the primary component.

Frequently Asked Questions (FAQ)

Q: Can CPF0805B82RE1 replace ACPP0805 82R B directly? A: Yes. CPF0805B82RE1 is a direct equivalent with identical resistance, tolerance, power rating, package, and operating specifications. No circuit modifications are required.

Q: What is the difference between direct equivalents and upgrade substitutes? A: Direct equivalents (CPF0805B82RE1) maintain identical 0.1W power rating. Upgrade substitutes (ERA-6AEB820V, RG2012P-820-B-T5, RT0805BRD0782RL) increase power rating to 0.125W and may include automotive certifications or environmental features.

Q: Are the upgrade substitutes compatible with designs specified for 0.1W? A: Yes. Upgrade substitutes with higher power ratings are compatible with circuits designed for 0.1W components. The increased power rating provides additional thermal margin without affecting electrical performance.

Q: What does AEC-Q200 certification indicate? A: AEC-Q200 is an automotive qualification standard. ERA-6AEB820V and RG2012P-820-B-T5 meet this certification for automotive applications requiring enhanced reliability and environmental stress testing.

Q: Does the anti-sulfur feature of RG2012P-820-B-T5 affect general-purpose applications? A: No. Anti-sulfur construction is beneficial in high-sulfur environments but does not negatively impact performance in standard applications. This feature provides additional environmental protection without circuit-level changes.

Q: Are all substitute parts available in the same package footprint? A: Yes. All parts use the 0805 (2012 Metric) package with identical land pattern dimensions (0.079" L x 0.049" W). PCB layout modifications are not required.

Q: What is the MSL rating and why is it important? A: MSL (Moisture Sensitivity Level) 1 indicates unlimited shelf life without moisture baking requirements. All listed parts carry MSL 1 rating, ensuring consistent handling and storage procedures.
