Key Parameters

Substitute Part Grouping Explanation

Substitution of the ERA-6YED302Z is determined by strict equivalence across the following parameters:

• Resistance value: 3 kOhms (exact match required)
• Tolerance: ±0.5% (exact match required)
• Power rating: 0.125W / 1/8W (exact match required)
• Package format: 0805 (2012 Metric) (exact match required)
• Temperature coefficient: ±25ppm/°C (exact match required)
• Operating temperature range: minimum -55°C, maximum ≥125°C
• RoHS3 compliance (required for regulatory continuity)
• Moisture sensitivity level: 1 (Unlimited)

The ERA-6AED302V qualifies as a direct substitute based on full alignment with these parameters. While the ERA-6AED series employs thin film composition versus the metal film composition of the ERA-6YED, both technologies deliver identical electrical performance within the specified tolerance and temperature coefficient constraints. The ERA-6AED302V additionally carries AEC-Q200 automotive qualification and extended operating temperature range (-55°C ~ 155°C), providing enhanced reliability margins without compromising compatibility.

Parameter Comparison

Engineering Selection Recommendations

The ERA-6AED302V is the qualified substitute for the obsolete ERA-6YED302Z. Both parts maintain identical electrical specifications (3 kOhms, ±0.5%, 0.125W, ±25ppm/°C) and mechanical compatibility (0805 package). The ERA-6AED302V is currently in active production with substantial inventory availability (210,904 pcs), ensuring supply chain continuity.

The ERA-6AED302V carries AEC-Q200 automotive qualification, which provides additional reliability assurance beyond the base specification. The extended operating temperature range (-55°C ~ 155°C versus -55°C ~ 125°C) offers performance margin for applications operating at elevated temperatures. Both parts maintain ROHS3 compliance and MSL 1 rating, preserving regulatory and handling requirements.

Selection of the ERA-6AED302V eliminates obsolescence risk while maintaining full electrical and mechanical interchangeability with the original ERA-6YED302Z specification.

Frequently Asked Questions (FAQ)

Q: Can the ERA-6AED302V be used as a direct replacement for ERA-6YED302Z in existing designs?

A: Yes. Both parts share identical resistance (3 kOhms), tolerance (±0.5%), power rating (0.125W), package format (0805), and temperature coefficient (±25ppm/°C). The ERA-6AED302V is mechanically and electrically interchangeable with no design modifications required.

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

A: Both metal film and thin film resistor technologies deliver the specified electrical performance within the stated tolerance and temperature coefficient. The composition difference does not affect functional compatibility for this application.

Q: Why does the ERA-6AED302V have a higher maximum operating temperature?

A: The ERA-6AED302V is rated to -55°C ~ 155°C, compared to -55°C ~ 125°C for the ERA-6YED302Z. This extended range reflects the enhanced thermal capability of the thin film technology and AEC-Q200 qualification. Applications operating within the original -55°C ~ 125°C range experience no change in performance.

Q: Is AEC-Q200 qualification required for my application?

A: AEC-Q200 is an automotive reliability standard. If your application does not require automotive qualification, the AEC-Q200 rating on the ERA-6AED302V provides additional assurance without introducing incompatibility. If automotive qualification is required, the ERA-6AED302V meets this requirement.

Q: Are there any packaging differences between these parts?

A: Both parts are supplied in 0805 (2012 Metric) package format with identical physical dimensions (0.079" L x 0.049" W, 2.00mm x 1.25mm) and height (0.024" maximum, 0.60mm). The ERA-6AED302V is available in Tape & Reel (TR) packaging, standard for production environments.

Q: What is the moisture sensitivity level, and does it affect handling?

A: Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. Standard handling procedures apply without special moisture control requirements.
