ACPP0805 2K7 B Equivalent & Substitute Parts

Part Overview

The ACPP0805 2K7 B is a 2.7 kOhms ±0.1% thin film chip resistor in 0805 (2012 Metric) package manufactured by Ohmite. This precision resistor is rated for 0.1W (1/10W) power dissipation with a temperature coefficient of ±25ppm/°C and operates across -55°C to 155°C. The part is ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating and is currently in active production status with 1022 units in stock.

Equivalent and substitute parts are necessary when the primary part experiences supply constraints, extended lead times, or when design requirements permit selection from qualified alternatives that maintain electrical and mechanical compatibility within the same package class.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ACPP0805 2K7 B are qualified based on the following criteria:

Mandatory Matching Parameters:

• Resistance value: 2.7 kOhms
• Tolerance: ±0.1%
• Package / Case: 0805 (2012 Metric)
• Composition: Thin Film
• Temperature Coefficient: ±25ppm/°C
• Operating Temperature Range: -55°C minimum to 155°C minimum
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation:

• Power rating may be equal to or greater than 0.1W
• Physical dimensions may vary within 0805 package specifications
• Additional features (automotive qualification, anti-sulfur coating) do not disqualify a part

Substitutes are grouped into two categories: direct equivalents (matching 0.1W power rating) and upgraded alternatives (higher power ratings with enhanced features).

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Matching 0.1W Rating): CPF0805B2K7E1 from TE Connectivity Passive Product is a direct functional equivalent with identical electrical specifications and power rating. This part maintains full compatibility with the original ACPP0805 2K7 B design without any circuit modifications.

Upgraded Alternatives (Higher Power Ratings): The following parts provide enhanced power dissipation capability while maintaining all critical electrical parameters:

• ERA-6AEB272V (Panasonic, 0.125W): Automotive AEC-Q200 qualified with active production status and highest inventory availability (13600 units).
• RG2012P-272-B-T5 (Susumu, 0.125W): Automotive AEC-Q200 qualified with anti-sulfur coating and highest inventory level (18237 units).
• RNCF0805BTE2K70 (Stackpole Electronics, 0.25W): Automotive AEC-Q200 qualified with highest power rating among substitutes.
• RT0805BRD072K7L (YAGEO, 0.125W): Standard thin film construction with active production status.
• TNPW08052K70BEEA (Vishay Dale, 0.26W): Automotive AEC-Q200 qualified with anti-sulfur and moisture-resistant features. Extended operating temperature range to 175°C.

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and ±25ppm/°C temperature coefficient. Selection among upgraded alternatives depends on circuit thermal requirements and automotive qualification needs.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with higher power rating than the original ACPP0805 2K7 B? A: Yes. A higher power rating (0.125W, 0.25W, or 0.26W) is electrically compatible and does not require circuit modification. The resistor will operate within its rated specifications in the same application. Physical dimensions remain within 0805 package tolerances.

Q: Are all substitute parts automotive qualified? A: No. CPF0805B2K7E1 and RT0805BRD072K7L do not carry AEC-Q200 qualification. ERA-6AEB272V, RG2012P-272-B-T5, RNCF0805BTE2K70, and TNPW08052K70BEEA are all AEC-Q200 qualified. Select based on your application requirements.

Q: What is the difference between the ACPP0805 2K7 B and ERA-6AEB272V? A: Both parts share identical resistance (2.7 kOhms), tolerance (±0.1%), temperature coefficient (±25ppm/°C), and operating range (-55°C to 155°C). The ERA-6AEB272V has a slightly higher power rating (0.125W vs 0.1W) and includes automotive AEC-Q200 qualification. Physical height differs by 0.002" (0.05mm).

Q: Can I substitute TNPW08052K70BEEA for ACPP0805 2K7 B in all applications? A: TNPW08052K70BEEA is electrically compatible with identical resistance and tolerance. It offers higher power dissipation (0.26W), extended temperature range to 175°C, anti-sulfur coating, and moisture-resistant features. These enhancements make it suitable for demanding environments but are not required for standard applications.

Q: Do all substitute parts have the same package dimensions? A: All parts use the 0805 (2012 Metric) package. Physical dimensions are nominally 0.079" L x 0.049" W (2.00mm x 1.25mm). Seated heights vary slightly: ACPP0805 2K7 B and RNCF0805BTE2K70 are 0.026" (0.65mm), while others range from 0.020" to 0.024". These variations are within standard 0805 package tolerances and do not affect PCB assembly compatibility.

Q: Which substitute has the best inventory availability? A: RG2012P-272-B-T5 from Susumu has the highest inventory at 18237 units, followed by ERA-6AEB272V from Panasonic at 13600 units. Both are suitable for immediate procurement.
