ERA-3YED392Z Equivalent & Substitute Parts

Part Overview

The ERA-3YED392Z is a 3.9 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 currently obsolete, with 791 units available in new original stock. Due to its obsolete status, identifying qualified substitute components is essential for ongoing production, maintenance, and design continuity. Substitute parts must maintain electrical equivalence across resistance value, tolerance, power rating, and package dimensions while meeting applicable compliance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERA-3YED392Z is determined by strict equivalence across the following critical parameters:

• Resistance value: 3.9 kOhms (exact match required)
• Tolerance: ±0.5% (exact match required)
• Power rating: 0.1W / 1/10W (exact match required)
• Package: 0603 (1608 Metric) (exact match required)
• Temperature coefficient: ±25ppm/°C (exact match required)
• Moisture sensitivity: MSL 1 or better (equal or lower MSL acceptable)
• RoHS compliance: ROHS3 Compliant (required for regulatory continuity)

The ERA-3AED392V qualifies as a direct substitute based on full alignment with these parameters. While the ERA-3AED392V uses thin film composition (versus metal film in the original) and includes automotive AEC-Q200 qualification, both technologies meet the specified electrical and mechanical requirements. The substitute part operates across an extended temperature range (-55°C ~ 155°C) and maintains active product status with significantly higher inventory availability (10,687 units).

Parameter Comparison

Engineering Selection Recommendations

The ERA-3AED392V is a qualified direct substitute for the obsolete ERA-3YED392Z. Both parts are manufactured by Panasonic Electronic Components and maintain full electrical and mechanical equivalence across all critical parameters: 3.9 kOhms resistance, ±0.5% tolerance, 0.1W power rating, and 0603 package dimensions.

The substitute part offers the following advantages:

• Active product status ensures long-term availability and supply chain continuity
• Extended operating temperature range (-55°C ~ 155°C versus -55°C ~ 125°C) provides additional thermal margin
• Automotive AEC-Q200 qualification indicates enhanced reliability and quality assurance
• Significantly higher inventory availability (10,687 units) supports production requirements
• ROHS3 compliance maintained for regulatory alignment

Both parts carry MSL 1 rating and identical moisture sensitivity characteristics, eliminating handling and storage requirement changes. The thin film composition of the substitute part, while different from the metal film original, delivers equivalent electrical performance within the specified tolerance and temperature coefficient parameters.

Frequently Asked Questions (FAQ)

Q: Can ERA-3AED392V be used as a direct replacement for ERA-3YED392Z in existing designs?

A: Yes. The ERA-3AED392V meets all electrical and mechanical specifications of the ERA-3YED392Z. Both parts share identical resistance (3.9 kOhms), tolerance (±0.5%), power rating (0.1W), package dimensions (0603), and temperature coefficient (±25ppm/°C). Physical footprint and PCB layout compatibility are identical.

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

A: Both metal film and thin film resistor technologies meet the specified electrical parameters for this application. The ERA-3AED392V thin film construction maintains the same tolerance, temperature coefficient, and power rating as the original metal film part.

Q: Does the extended temperature range of ERA-3AED392V affect compatibility?

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

Q: Are there any moisture sensitivity or handling differences?

A: No. Both parts carry MSL 1 (Unlimited) rating, indicating identical moisture sensitivity levels and storage requirements.

Q: What does AEC-Q200 qualification mean?

A: AEC-Q200 is an automotive industry standard qualification demonstrating enhanced reliability, quality assurance, and testing rigor. This certification does not affect electrical performance but indicates higher reliability standards applicable to automotive and mission-critical applications.

Q: Is the Tape & Reel packaging of ERA-3AED392V compatible with standard pick-and-place equipment?

A: Yes. Tape & Reel (TR) packaging is the standard format for automated surface mount assembly equipment and is compatible with all conventional PCB manufacturing processes.
