ERA-3YEB433V Equivalent & Substitute Parts

Part Overview

The ERA-3YEB433V is a 43 kOhms ±0.1% metal film chip resistor rated at 0.1W (1/10W) in 0603 (1608 Metric) surface mount package, manufactured by Panasonic Electronic Components. This part is classified as obsolete. Locating equivalent substitute parts is necessary due to the discontinued status of the original component, requiring selection from active product lines that maintain identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ERA-3YEB433V is determined by strict equivalence across the following parameters:

• Resistance value: 43 kOhms
• Tolerance: ±0.1%
• Power rating: 0.1W (1/10W)
• Package type: 0603 (1608 Metric)
• Temperature coefficient: ±25ppm/°C
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

The ERA-3AEB433V qualifies as a direct substitute based on matching all critical electrical parameters and package specifications. The substitute part operates across an extended temperature range (-55°C to 155°C) compared to the main part (-55°C to 125°C), providing broader environmental capability while maintaining identical nominal performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The ERA-3AEB433V is the qualified substitute for the obsolete ERA-3YEB433V. Both parts are manufactured by Panasonic Electronic Components and maintain identical electrical specifications (43 kOhms ±0.1%, 0.1W, ±25ppm/°C) and mechanical compatibility (0603 package, 1.60mm x 0.80mm dimensions).

The substitute part is currently in active production status with significantly higher inventory availability (10,351 pcs vs. 920 pcs). The ERA-3AEB433V carries AEC-Q200 automotive qualification and extends the operating temperature range to -55°C to 155°C, providing enhanced environmental performance. Both parts maintain ROHS3 compliance and MSL 1 moisture sensitivity rating.

Selection of the ERA-3AEB433V eliminates obsolescence risk while providing equivalent or superior performance characteristics for the specified application.

Frequently Asked Questions (FAQ)

Q: Can ERA-3AEB433V directly replace ERA-3YEB433V in existing designs?

A: Yes. Both parts share identical resistance (43 kOhms), tolerance (±0.1%), power rating (0.1W), package type (0603), and temperature coefficient (±25ppm/°C). Physical dimensions and termination count are identical, enabling direct board-level substitution.

Q: What is the difference between metal film and thin film composition?

A: The main part uses metal film construction; the substitute uses thin film construction. Both achieve the same ±0.1% tolerance and ±25ppm/°C temperature coefficient specifications required for this application.

Q: Does the extended temperature range of ERA-3AEB433V affect compatibility?

A: No. The substitute part operates from -55°C to 155°C, which encompasses the original part's -55°C to 125°C range. Extended temperature capability does not compromise compatibility in applications requiring the narrower range.

Q: What does AEC-Q200 qualification mean?

A: AEC-Q200 is an automotive industry standard qualification for passive components. The substitute part meets this automotive-grade reliability standard, though the original part does not carry this designation.

Q: Are both parts RoHS compliant?

A: Yes. Both ERA-3YEB433V and ERA-3AEB433V are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: What packaging options are available for the substitute part?

A: The ERA-3AEB433V is supplied in Tape & Reel (TR) packaging format.
