ERA-3YED201Z Equivalent & Substitute Parts

Part Overview

The ERA-3YED201Z is a 200 Ohms ±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 currently obsolete, with 1,087 pieces available in new original stock. Due to its discontinued status, identifying qualified substitute components is essential for ongoing production, maintenance, and design continuity. Substitute parts must maintain electrical performance and mechanical compatibility while meeting current availability and compliance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERA-3YED201Z is determined by strict alignment of the following electrical and mechanical parameters:

• Resistance value: 200 Ohms (exact match required)
• Tolerance: ±0.5% (exact match required)
• Power rating: 0.1W / 1/10W (exact match required)
• Package type: 0603 (1608 Metric) (exact match required)
• Temperature coefficient: ±25ppm/°C (exact match required)
• RoHS compliance: ROHS3 Compliant (minimum requirement)
• Moisture sensitivity: MSL 1 (Unlimited) (exact match required)

The ERA-3AED201V qualifies as a direct substitute based on these parameters. While the ERA-3AED201V uses thin film composition (versus metal film in the original) and features automotive AEC-Q200 qualification with an extended operating temperature range (-55°C to 155°C), these enhancements do not compromise compatibility and represent functional improvements for applications requiring higher temperature performance.

Engineering Selection Recommendations

The ERA-3AED201V is the qualified substitute for the obsolete ERA-3YED201Z. Selection should be based on the following factors:

Product Status & Availability: The ERA-3AED201V is active production with significantly higher inventory (35,951 pieces) compared to the obsolete ERA-3YED201Z (1,087 pieces). For new designs and ongoing production, the ERA-3AED201V ensures long-term supply continuity.

Compliance & Certifications: Both parts maintain ROHS3 compliance and MSL 1 rating. The ERA-3AED201V adds automotive AEC-Q200 qualification, which provides additional reliability assurance for applications requiring automotive-grade components.

Electrical & Mechanical Compatibility: Identical resistance, tolerance, power rating, temperature coefficient, and package dimensions ensure direct functional substitution without circuit redesign or PCB layout modification.

Operating Temperature Consideration: The ERA-3AED201V supports -55°C to 155°C versus -55°C to 125°C for the original part. This extended range provides design margin for applications operating at elevated temperatures.

Frequently Asked Questions (FAQ)

Q: Can ERA-3AED201V be used as a direct replacement for ERA-3YED201Z in existing designs?

A: Yes. Both parts share identical electrical specifications (200 Ohms ±0.5%, 0.1W, ±25ppm/°C) and mechanical package (0603 / 1608 Metric). No circuit modification or PCB redesign is required. The ERA-3AED201V can be substituted without functional impact.

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 technology, used in the ERA-3AED201V, is commonly employed in automotive-grade components and provides enhanced reliability characteristics.

Q: Why does ERA-3AED201V have a higher operating temperature range?

A: The ERA-3AED201V is rated to -55°C to 155°C, compared to -55°C to 125°C for the ERA-3YED201Z. This extended range reflects the automotive AEC-Q200 qualification and does not affect compatibility for applications operating within the original temperature range.

Q: Are there packaging differences between these parts?

A: The ERA-3YED201Z is supplied in bulk packaging, while the ERA-3AED201V is supplied in Tape & Reel (TR) format. Both are suitable for automated assembly processes. TR packaging is standard for active production components.

Q: Do both parts meet RoHS compliance requirements?

A: Yes. Both ERA-3YED201Z and ERA-3AED201V are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, meeting current environmental and reliability standards.
