ERA-2AEB433X Equivalent & Substitute Parts

Part Overview

The ERA-2AEB433X is a 43 kOhms ±0.1% thin film chip resistor in 0402 (1005 Metric) package rated at 0.063W (1/16W) power dissipation. Manufactured by Panasonic Electronic Components, this component meets Automotive AEC-Q200 qualification and operates across -55°C to 155°C. The part is active in production with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Equivalent and substitute parts are identified to support procurement flexibility, supply chain continuity, and design requirements across multiple manufacturing sources.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters: resistance value (43 kOhms), tolerance (±0.1%), package format (0402/1005 Metric), composition (thin film), temperature coefficient (±25ppm/°C), and compliance certifications (ROHS3, REACH Unaffected). All identified substitute parts match these core electrical and mechanical specifications. Power rating variations and operating temperature range extensions are noted where applicable but do not preclude substitution when thermal design margins are adequate. Packaging format (Tape & Reel versus Cut Tape) represents a procurement distinction without affecting electrical performance.

Engineering Selection Recommendations

All substitute parts maintain full electrical equivalence at the specified 43 kOhms ±0.1% resistance with identical thin film composition and temperature coefficient. Selection among substitutes should prioritize product status (all active), ROHS3 compliance (universal), and MSL 1 rating (universal).

For automotive applications requiring AEC-Q200 qualification, RG1005P-433-B-T5 (Susumu) and TNPW040243K0BEED (Vishay Dale) provide explicit automotive certification matching the primary part. CPF0402B43KE1 (TE Connectivity) and RT0402BRD0743KL (YAGEO) lack stated AEC-Q200 ratings and are suitable for non-automotive or general industrial applications.

TNPW040243K0BEED offers extended operating temperature range (-55°C to 175°C versus -55°C to 155°C) and higher power rating (0.13W versus 0.063W), providing thermal margin for applications with elevated ambient or power dissipation requirements. Height variations (0.014" to 0.016" seated maximum) are within typical PCB assembly tolerances and do not affect functional substitution.

Frequently Asked Questions (FAQ)

Q: Can CPF0402B43KE1 replace ERA-2AEB433X in automotive applications? A: CPF0402B43KE1 matches all electrical parameters but lacks stated AEC-Q200 automotive qualification. Use only in non-automotive or general industrial designs unless automotive certification is not a design requirement.

Q: What is the significance of the power rating difference in TNPW040243K0BEED? A: TNPW040243K0BEED is rated at 0.13W versus 0.063W for the primary part. This higher rating provides additional thermal margin and allows operation at higher power dissipation levels. It is a direct substitute where thermal performance is equal or improved.

Q: Are height differences between substitute parts critical? A: Height variations range from 0.014" to 0.016" seated maximum. These differences are within standard PCB assembly process tolerances and do not affect electrical performance or mechanical fit in standard 0402 footprints.

Q: Which substitute offers the widest operating temperature range? A: TNPW040243K0BEED operates from -55°C to 175°C, extending 20°C above the primary part and other substitutes. This is suitable for high-temperature applications or environments with elevated thermal stress.

Q: Do all substitutes meet RoHS and REACH compliance? A: All identified substitutes are ROHS3 compliant and REACH unaffected, matching the primary part's environmental compliance status.

Q: What is the difference between Tape & Reel and Cut Tape packaging? A: Tape & Reel (TR) and Cut Tape (CT) represent different supply formats for automated assembly. Both formats contain identical components; packaging selection depends on production equipment and procurement workflow. RT0402BRD0743KL is supplied in Cut Tape & Digi-Reel format while others use Tape & Reel.
