ERA-6YEB433V Equivalent & Substitute Parts

Part Overview

The ERA-6YEB433V is a 43 kOhm ±0.1% 0.125W (1/8W) chip resistor in 0805 (2012 Metric) package manufactured by Panasonic Electronic Components. This metal film resistor operates across -55°C to 125°C and is currently obsolete. Due to its discontinued status, equivalent substitute parts from active product lines are necessary for ongoing design support and procurement.

Substitute Part Grouping Explanation

Substitution for the ERA-6YEB433V is determined by the following critical parameters:

Core Electrical Parameters: Resistance value (43 kOhms), tolerance (±0.1%), and power rating (0.125W minimum) must match or exceed the original specification.

Package Compatibility: All substitutes must use the 0805 (2012 Metric) package with compatible footprint dimensions and height specifications.

Environmental Specifications: Operating temperature range must support the original -55°C to 125°C minimum. Substitutes with extended temperature ranges (-55°C to 155°C or higher) are acceptable.

Composition and Performance: Thin film resistors with equivalent or superior temperature coefficient performance (±25ppm/°C or better) are acceptable substitutes for the metal film original.

Compliance Requirements: All substitutes must maintain ROHS3 compliance and MSL 1 rating.

Substitute parts are grouped into two categories: direct equivalents from Panasonic's active ERA-6A series (thin film automotive-grade alternatives), and cross-manufacturer equivalents from Vishay, Susumu, and YAGEO that meet identical electrical and mechanical specifications.

Engineering Selection Recommendations

Primary Recommendation - Panasonic ERA-6A Series: The ERA-6AEB433V provides direct functional equivalence with active product status and AEC-Q200 automotive qualification. This is the preferred substitute for general applications. The ERA-6APB433V and ERA-6ARB433V offer improved temperature coefficient performance (±15ppm/°C and ±10ppm/°C respectively) for precision-critical circuits. The ERA-6ARW433V provides the tightest tolerance (±0.05%) for applications requiring enhanced accuracy.

Cross-Manufacturer Alternatives: The MCU08050D4302BP100 and MCU08050D4302BP500 from Vishay Beyschlag match the original temperature range (-55°C to 125°C) and electrical specifications exactly. The RG2012P-433-B-T5 from Susumu combines AEC-Q200 qualification with extended temperature range and anti-sulfur protection. The RT0805BRD0743KL from YAGEO provides cost-effective equivalence with extended operating temperature.

Enhanced Performance Options: The TNPW080543K0BEEA and TNPW080543K0BEEN from Vishay Dale offer doubled power rating (0.26W), extended temperature range (-55°C to 175°C), AEC-Q200 qualification, and moisture-resistant construction. These are suitable for applications requiring thermal margin or harsh environmental conditions.

Compliance Considerations: For automotive applications, select parts with AEC-Q200 certification: ERA-6AEB433V, ERA-6APB433V, ERA-6ARB433V, ERA-6ARW433V, RG2012P-433-B-T5, TNPW080543K0BEEA, or TNPW080543K0BEEN. All substitutes maintain ROHS3 compliance and MSL 1 rating.

Frequently Asked Questions (FAQ)

Q: Can I use ERA-6ARW433V as a direct replacement for ERA-6YEB433V?

A: Yes. The ERA-6ARW433V is a direct substitute with identical resistance, tolerance, power rating, and package. It offers superior specifications with ±0.05% tolerance (tighter than the original ±0.1%), lower temperature coefficient (±10ppm/°C vs. ±25ppm/°C), extended operating temperature range (-55°C to 155°C vs. -55°C to 125°C), and active product status with AEC-Q200 qualification.

Q: What is the difference between ERA-6AEB433V, ERA-6APB433V, and ERA-6ARB433V?

A: All three are Panasonic ERA-6A series thin film 0805 resistors with 43 kOhm resistance and ±0.1% tolerance. The primary differences are temperature coefficient performance: ERA-6AEB433V has ±25ppm/°C, ERA-6APB433V has ±15ppm/°C, and ERA-6ARB433V has ±10ppm/°C. Select based on circuit precision requirements.

Q: Can I use TNPW080543K0BEEA instead of ERA-6YEB433V?

A: Yes, with consideration for power rating. The TNPW080543K0BEEA has doubled power capacity (0.26W vs. 0.125W), extended temperature range (-55°C to 175°C), AEC-Q200 qualification, and moisture-resistant construction. It is electrically and mechanically compatible but occupies the same 0805 footprint with slightly different height (0.022" vs. 0.024" maximum seated height).

Q: Are MCU08050D4302BP100 and MCU08050D4302BP500 interchangeable?

A: Yes. Both are Vishay Beyschlag MCU series 43 kOhm ±0.1% 0.125W 0805 resistors with identical electrical specifications. The part number suffix indicates packaging reel size (100 vs. 500 pieces per reel). Electrical performance is identical.

Q: Which substitute offers the best temperature stability?

A: The ERA-6ARW433V and ERA-6ARB433V offer the lowest temperature coefficient at ±10ppm/°C. For applications requiring maximum thermal stability across the full operating range, these Panasonic parts provide superior performance compared to the original ±25ppm/°C specification.

Q: Do all substitutes maintain the same footprint compatibility?

A: Yes. All substitute parts use the 0805 (2012 Metric) package with identical land pattern dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm). Maximum seated heights vary slightly (0.020" to 0.024"), but all are within standard PCB assembly tolerances and compatible with existing 0805 footprints.

Q: Which substitutes are suitable for automotive applications?

A: Parts with AEC-Q200 certification are qualified for automotive use: ERA-6AEB433V, ERA-6APB433V, ERA-6ARB433V, ERA-6ARW433V, RG2012P-433-B-T5, TNPW080543K0BEEA, and TNPW080543K0BEEN. Non-automotive qualified alternatives include MCU08050D4302BP100, MCU08050D4302BP500, and RT0805BRD0743KL.
