ERA-3YED272Z Equivalent & Substitute Parts

Part Overview

The ERA-3YED272Z is a 2.7 kOhms ±0.5% metal film chip resistor rated at 0.1W (1/10W) in 0603 (1608 Metric) package format. This part is currently obsolete, which necessitates identification of functionally equivalent alternatives for ongoing design support and procurement. The ERA-3YED series has been superseded by active production alternatives that maintain electrical and mechanical compatibility while offering extended availability and enhanced specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ERA-3YED272Z is determined by strict equivalence across the following parameters:

• Resistance value: 2.7 kOhms (exact match required)
• Tolerance: ±0.5% (exact match required)
• Power rating: 0.1W / 1/10W (exact match required)
• Package format: 0603 (1608 Metric) (exact match required)
• Temperature coefficient: ±25ppm/°C (exact match required)
• Operating temperature range: minimum -55°C, maximum ≥125°C
• RoHS3 compliance: required
• Moisture sensitivity level: 1 (Unlimited)

The ERA-3AED272V qualifies as a direct substitute based on full alignment with these parameters. While the ERA-3AED series incorporates thin film composition and automotive AEC-Q200 qualification (enhancements not present in the original part), these represent functional improvements that do not compromise backward compatibility.

Parameter Comparison

Engineering Selection Recommendations

The ERA-3AED272V is the direct equivalent for ERA-3YED272Z replacement. Both parts maintain identical electrical specifications (2.7 kOhms, ±0.5%, 0.1W) and mechanical compatibility (0603 package, identical dimensions and termination count). The ERA-3AED272V offers extended operating temperature range (-55°C ~ 155°C versus -55°C ~ 125°C) and automotive AEC-Q200 qualification, representing functional enhancements. Both parts are ROHS3 compliant with MSL 1 rating. The ERA-3AED272V is currently in active production with substantial inventory availability, eliminating obsolescence risk associated with the original part.

Frequently Asked Questions (FAQ)

Q: Can ERA-3AED272V be used as a direct replacement for ERA-3YED272Z in existing designs?

A: Yes. Both parts share identical resistance (2.7 kOhms), tolerance (±0.5%), power rating (0.1W), package format (0603), and temperature coefficient (±25ppm/°C). Mechanical dimensions and termination configuration are identical. No circuit redesign or PCB modification is required.

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

A: Both compositions meet the specified electrical parameters for this application. Thin film construction in the ERA-3AED272V provides enhanced stability and precision characteristics. The substitution is valid based on matching electrical performance and tolerance specifications.

Q: Does the extended operating temperature range of ERA-3AED272V affect compatibility?

A: No. The ERA-3AED272V operating range (-55°C ~ 155°C) encompasses the original part's range (-55°C ~ 125°C). Extended temperature capability does not compromise performance within the original design envelope.

Q: Are there packaging differences between these parts?

A: The ERA-3YED272Z is supplied in standard packaging. The ERA-3AED272V is supplied in Tape & Reel (TR) format. Both use identical 0603 (1608 Metric) component packages. Tape & Reel packaging is standard for automated assembly processes and does not affect component performance or PCB compatibility.

Q: What is AEC-Q200 qualification?

A: AEC-Q200 is an automotive industry standard qualification for passive components. This certification indicates the ERA-3AED272V meets automotive reliability and performance requirements. This qualification is an enhancement and does not restrict use in non-automotive applications.

Q: Are both parts RoHS3 compliant?

A: Yes. Both ERA-3YED272Z and ERA-3AED272V are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.
