ERA-3YED101Z Equivalent & Substitute Parts

Part Overview

The ERA-3YED101Z is a 100 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, making identification of compatible substitute components essential for ongoing production, repair, and design applications. The obsolete status necessitates sourcing equivalent alternatives that maintain identical electrical and mechanical specifications to ensure seamless integration into existing designs and assemblies.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ERA-3YED101Z is determined by strict equivalence across the following critical parameters:

• Resistance Value: Must be 100 Ohms
• Tolerance: Must be ±0.5%
• Power Rating: Must be 0.1W (1/10W)
• Package / Case: Must be 0603 (1608 Metric)
• Temperature Coefficient: Must be ±25ppm/°C
• Operating Temperature Range: Must support minimum -55°C ~ 125°C
• RoHS Compliance: Must maintain ROHS3 Compliant status

The ERA-3AED101V meets all substitution criteria. While it features thin film composition (versus metal film) and includes automotive AEC-Q200 qualification with an extended upper operating temperature of 155°C, these represent enhancements rather than deviations from the core electrical and mechanical requirements. The substitute maintains identical resistance, tolerance, power rating, package dimensions, temperature coefficient, and RoHS compliance.

Parameter Comparison

Engineering Selection Recommendations

The ERA-3AED101V is a direct functional equivalent to the obsolete ERA-3YED101Z. Both components share identical electrical specifications (100 Ohms ±0.5%, 0.1W), mechanical dimensions (0603 package), and thermal characteristics (±25ppm/°C temperature coefficient). Both maintain ROHS3 compliance and MSL 1 rating.

The ERA-3AED101V is manufactured by the same supplier (Panasonic Electronic Components) and carries active product status, ensuring long-term availability and supply chain continuity. The substitute's extended operating temperature range (-55°C ~ 155°C versus -55°C ~ 125°C) and automotive AEC-Q200 qualification provide additional performance margin without introducing incompatibility.

Selection of the ERA-3AED101V eliminates obsolescence risk while maintaining full electrical and mechanical compatibility with designs originally specified for the ERA-3YED101Z.

Frequently Asked Questions (FAQ)

Q: Can ERA-3AED101V be used as a direct replacement for ERA-3YED101Z?

A: Yes. Both components meet identical specifications for resistance value (100 Ohms), tolerance (±0.5%), power rating (0.1W), package dimensions (0603), and temperature coefficient (±25ppm/°C). The substitute is pin-compatible and functionally equivalent.

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

A: Both compositions are provided in the specifications. The ERA-3YED101Z uses metal film construction, while the ERA-3AED101V uses thin film construction. Both achieve the same electrical performance parameters required for this application.

Q: Does the extended operating temperature range of ERA-3AED101V affect compatibility?

A: No. The ERA-3AED101V supports -55°C ~ 155°C, which encompasses the original part's -55°C ~ 125°C range. This represents an enhancement that does not compromise compatibility with existing designs.

Q: Are both parts RoHS compliant?

A: Yes. Both ERA-3YED101Z and ERA-3AED101V are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the packaging difference between these parts?

A: The ERA-3YED101Z is supplied in standard packaging. The ERA-3AED101V is supplied in Tape & Reel (TR) format. Both use identical 0603 (1608 Metric) surface mount package dimensions and are compatible with standard pick-and-place assembly equipment.

Q: Why is ERA-3YED101Z obsolete?

A: Product obsolescence is determined by the manufacturer. The ERA-3AED101V, as an active product from the same manufacturer with equivalent specifications, provides continuity for applications requiring 100 Ohms ±0.5% 0.1W 0603 resistors.
