ERA-3YED432Z Equivalent & Substitute Parts

Part Overview

The ERA-3YED432Z is a 4.3 kOhms ±0.5% metal film chip resistor rated at 0.1W (1/10W) in 0603 (1608 Metric) package format, manufactured by Panasonic Electronic Components. This part is classified as obsolete. Locating equivalent substitute parts is necessary due to the discontinued status of the ERA-3Y series, while maintaining identical electrical and mechanical specifications for direct circuit board replacement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ERA-3YED432Z is determined by strict equivalence across the following parameters:

• Resistance value: 4.3 kOhms
• Tolerance: ±0.5%
• Power rating: 0.1W (1/10W)
• Package format: 0603 (1608 Metric)
• Temperature coefficient: ±25ppm/°C
• Physical dimensions and termination count
• RoHS3 compliance and MSL rating

The ERA-3AED432V qualifies as a direct substitute based on matching all electrical specifications and mechanical form factor. The substitute part maintains identical resistance, tolerance, power rating, package dimensions, and environmental ratings. Differences in composition (thin film vs. metal film) and operating temperature range extension do not preclude substitution where the original operating temperature range is sufficient for the application.

Parameter Comparison

Engineering Selection Recommendations

The ERA-3AED432V is a suitable substitute for the obsolete ERA-3YED432Z. Both parts are manufactured by Panasonic Electronic Components and maintain identical electrical specifications (4.3 kOhms ±0.5%, 0.1W) and mechanical form factor (0603 package). The substitute part is currently in active production status with high inventory availability (55,290 pcs), ensuring supply chain continuity.

The ERA-3AED432V carries AEC-Q200 automotive qualification, which provides additional reliability assurance beyond the base specification. The extended operating temperature range (-55°C ~ 155°C vs. -55°C ~ 125°C) offers broader environmental capability. Both parts maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard PCB assembly processes.

Frequently Asked Questions (FAQ)

Q: Can ERA-3AED432V replace ERA-3YED432Z in existing designs?

A: Yes. Both parts share identical resistance (4.3 kOhms), tolerance (±0.5%), power rating (0.1W), package format (0603), temperature coefficient (±25ppm/°C), and physical dimensions. Direct substitution is electrically and mechanically compatible.

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

A: Both compositions meet the specified tolerance (±0.5%) and temperature coefficient (±25ppm/°C) for this application. Thin film construction in the ERA-3AED432V provides enhanced stability and is qualified to automotive standards (AEC-Q200).

Q: Does the extended operating temperature range of ERA-3AED432V affect compatibility?

A: No. The substitute part's extended range (-55°C ~ 155°C) is a superset of the original specification (-55°C ~ 125°C). Applications operating within the original temperature range remain fully compatible.

Q: Are both parts RoHS compliant?

A: Yes. Both ERA-3YED432Z and ERA-3AED432V are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, meeting standard PCB assembly and storage requirements.

Q: What packaging options are available for ERA-3AED432V?

A: The ERA-3AED432V is supplied in Tape & Reel (TR) format. Confirm packaging requirements for your procurement process.
