ACPP0805 4K3 B Equivalent & Substitute Parts

Part Overview

The ACPP0805 4K3 B is a 4.3 kOhms ±0.1% thin film chip resistor in 0805 (2012 Metric) package rated at 0.1W (1/10W) power dissipation. Manufactured by Ohmite under the ARCOL and ACPP series, this component is Active status and ROHS3 compliant. Equivalent and substitute parts are identified based on matching electrical specifications (resistance value, tolerance, temperature coefficient, operating temperature range) and mechanical compatibility (package type, form factor, termination count). Alternative sources become necessary for supply chain optimization, inventory availability, or application-specific requirements such as automotive qualification or enhanced power ratings.

Tolerance: ±0.1% (exact match required)
Package / Case: 0805 (2012 Metric) (exact match required)
Composition: Thin Film (exact match required)
Temperature Coefficient: ±25ppm/°C (exact match required)
Operating Temperature Range: -55°C ~ 155°C minimum (equal or extended range acceptable)
Number of Terminations: 2 (exact match required)
RoHS Status: ROHS3 Compliant (exact match required)
Moisture Sensitivity Level: 1 (exact match required)

Substitute parts are grouped into two categories:

Direct Equivalents: Parts meeting all mandatory parameters with identical power ratings (0.1W).

Upgrade Substitutes: Parts meeting all mandatory parameters with enhanced power ratings (0.125W, 0.25W, or 0.26W), automotive AEC-Q200 qualification, or additional features (anti-sulfur, moisture resistant). These provide functional equivalence with additional performance margins or certifications.

Frequently Asked Questions (FAQ)

Q: Can CPF0805B4K3E1 be used as a direct replacement for ACPP0805 4K3 B?

A: Yes. CPF0805B4K3E1 matches all electrical specifications (4.3 kOhms ±0.1%, 0.1W, ±25ppm/°C) and mechanical parameters (0805 package, 2-termination, identical dimensions). Both are Active status and ROHS3 compliant. No circuit redesign is required.

Q: What is the difference between the main part and upgrade substitutes?

A: Upgrade substitutes (ERA-6AEB432V, RG2012P-432-B-T5, RNCF0805BTE4K30, RT0805BRD074K3L, TNPW08054K30BEEA) provide higher power ratings (0.125W to 0.26W) compared to the 0.1W main part. All maintain identical resistance, tolerance, temperature coefficient, and operating temperature range. Higher power ratings provide additional thermal margin in applications with elevated ambient temperatures or higher current density. Some upgrade substitutes include automotive AEC-Q200 qualification or anti-sulfur features.

Q: Are all substitute parts compatible with the same PCB footprint?

A: Yes. All parts use the 0805 (2012 Metric) package with identical length (0.079") and width (0.049"). Height variations (0.020" to 0.026" seated maximum) are within standard PCB assembly tolerances and do not affect footprint compatibility. Reflow soldering parameters remain unchanged.

Q: Which substitute part should be selected for automotive applications?

A: ERA-6AEB432V (Panasonic), RG2012P-432-B-T5 (Susumu), RNCF0805BTE4K30 (Stackpole), and TNPW08054K30BEEA (Vishay Dale) carry AEC-Q200 automotive qualification. Selection depends on specific power rating requirements and additional features (anti-sulfur, moisture resistant). TNPW08054K30BEEA offers the highest power rating (0.26W) and extended temperature range (-55°C ~ 175°C).

Q: What is the operating temperature range difference for TNPW08054K30BEEA?

A: TNPW08054K30BEEA extends the upper operating temperature limit to 175°C compared to 155°C for the main part and other substitutes. This extended range is suitable for high-temperature automotive or industrial applications. All other electrical specifications remain identical.

Q: Are moisture sensitivity levels identical across all parts?

A: Yes. All parts, including the main component and all substitutes, have MSL 1 (Unlimited) rating. This indicates no moisture sensitivity and no special storage or handling requirements prior to soldering.

Q: Can upgrade substitutes with higher power ratings be used in circuits designed for 0.1W resistors?

A: Yes. Higher power-rated components are functionally equivalent and can be used in circuits designed for lower power ratings. The higher power rating provides additional thermal margin and does not affect circuit operation. No circuit modifications are required.
