Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following mandatory parameters:

• Resistance value: 2.4 kOhms
• Tolerance: ±0.1%
• Package / Case: 0805 (2012 Metric)
• Composition: Thin Film
• Temperature Coefficient: ±25ppm/°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

All substitute parts listed maintain these core specifications. Variations in power rating (0.1W, 0.125W, or 0.26W), operating temperature upper limit (-55°C ~ 155°C, -55°C ~ 175°C), and automotive certifications (AEC-Q200) represent upgrades or enhanced capabilities that do not compromise compatibility with the original design intent.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts are active products with ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard PCB assembly processes.

CPF0805B2K4E1 (TE Connectivity) provides direct electrical and thermal equivalence to the ACPP0805 2K4 B with identical power rating and operating temperature range.

ERA-6AEB242V (Panasonic), RG2012P-242-B-T5 (Susumu), and RT0805BRD072K4L (YAGEO) offer increased power dissipation (0.125W) and automotive AEC-Q200 qualification. These are suitable for applications requiring enhanced reliability margins or automotive-grade component certification.

TNPW08052K40BEEA (Vishay Dale) provides the highest power rating (0.26W) and extended operating temperature range (-55°C ~ 175°C), with anti-sulfur and moisture-resistant properties. This part is appropriate for high-reliability applications or environments with elevated temperature exposure.

Frequently Asked Questions (FAQ)

Q: Can I substitute the ACPP0805 2K4 B with any of these parts without circuit redesign?

A: Yes. All substitute parts maintain the same resistance value (2.4 kOhms), tolerance (±0.1%), package (0805), and temperature coefficient (±25ppm/°C). The 0805 package footprint is identical across all parts, enabling direct PCB-level substitution.

Q: What is the difference between the 0.1W and 0.125W power ratings?

A: The ACPP0805 2K4 B is rated at 0.1W, while ERA-6AEB242V, RG2012P-242-B-T5, and RT0805BRD072K4L are rated at 0.125W. Higher power ratings provide greater thermal margin and are suitable for applications with higher current or ambient temperature conditions. A 0.125W or 0.26W rated part can replace a 0.1W part without circuit modification.

Q: Are automotive-qualified parts (AEC-Q200) interchangeable with non-automotive parts?

A: Yes. AEC-Q200 qualification indicates enhanced reliability testing and is a superset of standard commercial specifications. Automotive-qualified parts (ERA-6AEB242V, RG2012P-242-B-T5, TNPW08052K40BEEA) can replace non-automotive parts in any application.

Q: What does the anti-sulfur feature on RG2012P-242-B-T5 and TNPW08052K40BEEA mean?

A: Anti-sulfur construction protects the component from corrosion in environments with hydrogen sulfide exposure. This feature does not affect electrical performance and is transparent to standard applications.

Q: Can I use TNPW08052K40BEEA in place of ACPP0805 2K4 B?

A: Yes. TNPW08052K40BEEA exceeds the original specification with higher power rating (0.26W vs. 0.1W), extended temperature range (-55°C ~ 175°C vs. -55°C ~ 155°C), and additional protective features. It is fully compatible at the circuit level.

Q: What is the significance of MSL 1 (Unlimited) rating?

A: MSL 1 indicates unlimited shelf life and no moisture bake-out requirement before soldering. All listed parts share this rating, ensuring consistent handling and storage procedures.
