ERA-3YED433Z Equivalent & Substitute Parts

Part Overview

The ERA-3YED433Z is a 43 kOhms ±0.5% 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 or compatible electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ERA-3YED433Z is determined by strict equivalence across the following parameters:

• Resistance value: 43 kOhms
• Tolerance: ±0.5%
• Power rating: 0.1W (1/10W)
• Package: 0603 (1608 Metric)
• Temperature coefficient: ±25ppm/°C
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

The ERA-3AED433V meets all substitution criteria. While the ERA-3AED433V uses thin film composition (versus metal film in the original) and extends the operating temperature range to -55°C ~ 155°C, these represent functional improvements. The ERA-3AED433V is an active product with automotive AEC-Q200 qualification, providing enhanced availability and reliability assurance.

Parameter Comparison

Engineering Selection Recommendations

The ERA-3AED433V is the direct substitute for the obsolete ERA-3YED433Z. Both components share identical electrical specifications (43 kOhms, ±0.5% tolerance, 0.1W power rating, ±25ppm/°C temperature coefficient) and mechanical compatibility (0603 package, identical dimensions and termination count). Both maintain ROHS3 compliance and MSL 1 rating.

The ERA-3AED433V offers the advantage of active product status with AEC-Q200 automotive qualification, ensuring continued availability and manufacturing support. The extended operating temperature range (-55°C ~ 155°C versus -55°C ~ 125°C) provides additional thermal margin for applications requiring higher temperature performance. The thin film composition of the substitute maintains the precision tolerance specification required for the application.

Frequently Asked Questions (FAQ)

Q: Can ERA-3AED433V directly replace ERA-3YED433Z in existing designs?

A: Yes. Both components share identical resistance (43 kOhms), tolerance (±0.5%), power rating (0.1W), package (0603), and temperature coefficient (±25ppm/°C). Mechanical dimensions and termination configuration are identical, enabling direct PCB-level substitution without design modification.

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

A: Both compositions meet the specified tolerance and temperature coefficient requirements. Thin film technology used in the ERA-3AED433V provides enhanced stability and precision characteristics while maintaining full compatibility with the original metal film specification.

Q: Does the extended operating temperature range of ERA-3AED433V affect compatibility?

A: No. The extended range (-55°C ~ 155°C versus -55°C ~ 125°C) represents a functional enhancement. Applications operating within the original temperature range remain fully compatible.

Q: What is AEC-Q200 qualification?

A: AEC-Q200 is an automotive industry standard qualification for passive components, confirming reliability and quality assurance for automotive applications. This certification does not restrict use in non-automotive applications.

Q: Are both parts RoHS compliant?

A: Yes. Both ERA-3YED433Z and ERA-3AED433V are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.
