ACPP0805 1K1 B Equivalent & Substitute Parts

Part Overview

The ACPP0805 1K1 B is a 1.1 kOhms ±0.1% thin film chip resistor manufactured by Ohmite in the 0805 (2012 Metric) package format. This component 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 747 units in stock.

Equivalent and substitute parts are necessary when the primary part becomes unavailable, when supply chain constraints require alternative sourcing, or when design requirements allow for upgraded specifications that maintain backward compatibility with the original electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ACPP0805 1K1 B is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 1.1 kOhms
• Tolerance: ±0.1%
• Package / Case: 0805 (2012 Metric)
• Composition: Thin Film
• Temperature Coefficient: ±25ppm/°C
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation Parameters:

• Power Rating: Equal to or greater than 0.1W
• Operating Temperature Range: Must encompass or exceed -55°C ~ 155°C
• RoHS Status: ROHS3 Compliant preferred; non-compliant parts listed for reference only
• Manufacturer and series designation: May vary

All substitute parts listed maintain identical electrical characteristics (resistance, tolerance, temperature coefficient) and physical package specifications. Differences in power rating and operating temperature represent upgrades that do not compromise compatibility.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Same Specifications): CPF0805B1K1E1 from TE Connectivity provides identical electrical and mechanical specifications to the ACPP0805 1K1 B. This part is suitable for direct substitution in applications where RoHS3 compliance is not a design requirement. With 1525 units in stock, this option offers immediate availability.

Upgraded Substitutes (Enhanced Power Rating): ERA-6AEB112V (Panasonic), RG2012P-112-B-T5 (Susumu), RT0805BRD071K1L (YAGEO), TNPW08051K10BEEA, and TNPW08051K10BEEN (Vishay Dale) all provide higher power ratings (0.125W to 0.26W) while maintaining identical resistance, tolerance, and temperature coefficient specifications. These parts are ROHS3 compliant and suitable for applications requiring enhanced thermal performance or design margin. The Vishay Dale variants extend the operating temperature range to 175°C.

Highest Power Rating Option: RP73PF2A1K1BTDF from TE Connectivity offers 0.25W power rating with ROHS3 compliance, providing maximum thermal headroom within the 0805 package format while maintaining all other electrical parameters.

Automotive-Qualified Options: ERA-6AEB112V (Panasonic), RG2012P-112-B-T5 (Susumu), TNPW08051K10BEEA, and TNPW08051K10BEEN (Vishay Dale) carry AEC-Q200 automotive qualification. RG2012P-112-B-T5 additionally features anti-sulfur protection. These options are appropriate for automotive and harsh environment applications.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with higher power rating than the original ACPP0805 1K1 B? A: Yes. All listed substitute parts with power ratings of 0.125W, 0.25W, or 0.26W are electrically and mechanically compatible. Higher power ratings do not affect circuit performance and provide additional thermal margin. The 0805 package dimensions remain identical across all listed parts.

Q: What is the difference between TNPW08051K10BEEA and TNPW08051K10BEEN? A: Both parts are identical in electrical specifications, power rating (0.26W), and package format. They differ only in manufacturing lot or packaging designation. Both are suitable substitutes with equivalent performance characteristics.

Q: Are all substitute parts ROHS3 compliant? A: CPF0805B1K1E1 is RoHS non-compliant. All other listed substitutes (ERA-6AEB112V, RG2012P-112-B-T5, RP73PF2A1K1BTDF, RT0805BRD071K1L, TNPW08051K10BEEA, TNPW08051K10BEEN) are ROHS3 compliant. Verify compliance requirements for your application before selection.

Q: Do substitute parts maintain the same physical dimensions? A: Yes. All substitute parts use the 0805 (2012 Metric) package with identical length (0.079") and width (0.049"). Height variations are minimal (0.020" to 0.026" seated height) and do not affect PCB layout or assembly compatibility.

Q: Which substitute offers the widest operating temperature range? A: TNPW08051K10BEEA and TNPW08051K10BEEN extend the upper operating temperature to 175°C compared to 155°C for the original part. This provides additional margin for high-temperature applications.

Q: Can I use ERA-6AEB112V or RG2012P-112-B-T5 in automotive applications? A: Yes. Both parts carry AEC-Q200 automotive qualification. RG2012P-112-B-T5 additionally includes anti-sulfur protection for enhanced reliability in corrosive environments.
