Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ACPP0805 1K8 B are qualified based on the following critical parameters:

Electrical Compatibility: Resistance value (1.8 kOhms), tolerance (±0.1%), and composition (thin film) must match exactly. Temperature coefficient (±25ppm/°C) and operating temperature range (-55°C to at least 155°C) must be equivalent or superior.

Mechanical Compatibility: Package type (0805/2012 Metric) and footprint dimensions (0.079" L × 0.049" W / 2.00mm × 1.25mm) must be identical for direct PCB replacement.

Environmental & Compliance: All substitutes must maintain ROHS3 compliance and MSL 1 rating. Automotive AEC-Q200 certification is an upgrade feature available in certain alternatives.

Power Rating Consideration: The main part is rated at 0.1W. Substitute parts with equal or higher power ratings (0.125W, 0.26W) are functionally compatible and provide design margin.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Identical Specifications): CPF0805B1K8E1 from TE Connectivity Passive Product matches the ACPP0805 1K8 B specification exactly across all electrical and mechanical parameters. This part is suitable for one-to-one replacement without circuit redesign.

Upgraded Alternatives (Higher Power Rating): ERA-6AEB182V, RG2012P-182-B-T5, RT0805BRD071K8L, and TNPW08051K80BEEA all provide equal or superior power ratings (0.125W to 0.26W) while maintaining identical resistance, tolerance, and temperature coefficient specifications. These parts offer increased thermal margin and are compatible with the original PCB footprint.

Automotive-Qualified Options: ERA-6AEB182V, RG2012P-182-B-T5, and TNPW08051K80BEEA carry AEC-Q200 automotive qualification. RG2012P-182-B-T5 additionally features anti-sulfur coating. TNPW08051K80BEEA extends the upper operating temperature to 175°C.

Compliance & Availability: All substitute parts maintain ROHS3 compliance and MSL 1 rating. Selection should be based on application requirements, supply chain availability, and any automotive or environmental specifications mandated by the end application.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with higher power rating than the original ACPP0805 1K8 B? A: Yes. Parts rated at 0.125W or 0.26W are electrically and mechanically compatible. Higher power ratings provide additional thermal margin without affecting circuit performance, provided the PCB layout and thermal management remain unchanged.

Q: What is the difference between the ACPP0805 1K8 B and ERA-6AEB182V? A: Both parts share identical electrical specifications (1.8 kΩ, ±0.1%, ±25ppm/°C, -55°C to 155°C). ERA-6AEB182V has a higher power rating (0.125W vs 0.1W) and carries AEC-Q200 automotive certification. Physical dimensions are equivalent for PCB compatibility.

Q: Are all substitute parts suitable for automotive applications? A: Only ERA-6AEB182V, RG2012P-182-B-T5, and TNPW08051K80BEEA carry AEC-Q200 certification. For non-automotive applications, all listed substitutes are functionally equivalent. Verify application requirements before selection.

Q: Will substitute parts fit the same PCB footprint as ACPP0805 1K8 B? A: Yes. All substitute parts use the 0805 (2012 Metric) package with identical footprint dimensions (0.079" L × 0.049" W / 2.00mm × 1.25mm). Direct PCB replacement is supported without layout modification.

Q: What is the temperature coefficient specification and why does it matter? A: All listed parts maintain ±25ppm/°C temperature coefficient, matching the original specification. This parameter defines resistance drift over the operating temperature range and is critical for precision circuit applications. Identical coefficients ensure equivalent circuit performance across temperature extremes.

Q: Is moisture sensitivity a concern when substituting parts? A: All parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity limitations. Standard PCB assembly and storage practices apply equally to all substitutes.
