Key Parameters

Substitute Part Grouping Explanation

Substitution of the ERA-2HEC3090P is determined by strict equivalence across the following parameters:

• Resistance value: 309 Ohms
• Tolerance: ±0.25%
• Power rating: 0.063W (1/16W)
• Package type: 0402 (1005 Metric)
• Composition: Thin Film
• Temperature coefficient: ±25ppm/°C
• Termination count: 2
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

The ERA-2AEC3090X meets all these criteria and qualifies as a direct substitute. The primary distinction is product status and operating temperature range extension.

Parameter Comparison

Engineering Selection Recommendations

The ERA-2AEC3090X is the qualified substitute for the obsolete ERA-2HEC3090P. Both components share identical electrical specifications (309 Ohms, ±0.25% tolerance, 0.063W power rating) and mechanical compatibility (0402 package, thin film composition, ±25ppm/°C temperature coefficient).

The ERA-2AEC3090X offers two advantages:

• Active product status ensures ongoing availability and supply chain continuity
• Extended operating temperature range (-55°C ~ 155°C versus -55°C ~ 125°C) provides additional thermal margin
• AEC-Q200 automotive qualification provides enhanced reliability documentation

Both components maintain ROHS3 compliance and MSL 1 moisture sensitivity rating, ensuring compatibility with standard manufacturing and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can ERA-2AEC3090X be used as a direct replacement for ERA-2HEC3090P?

A: Yes. Both components have identical resistance (309 Ohms), tolerance (±0.25%), power rating (0.063W), package (0402), composition (thin film), and temperature coefficient (±25ppm/°C). Electrical and mechanical compatibility is complete.

Q: What is the difference between ERA-2H and ERA-2A series?

A: The ERA-2A series includes AEC-Q200 automotive qualification and extended operating temperature range (-55°C ~ 155°C) compared to the ERA-2H series (-55°C ~ 125°C). Both series use identical thin film technology and package formats.

Q: Does the extended temperature range of ERA-2AEC3090X affect circuit performance?

A: No. The extended range indicates the component is rated for operation up to 155°C. If your application operates within the original -55°C ~ 125°C range, both components perform identically within that window.

Q: Are there any PCB layout or soldering differences between these parts?

A: No. Both components use the 0402 (1005 Metric) package with identical dimensions (0.039" L x 0.020" W, 1.00mm x 0.50mm) and height (0.016" maximum seated height). PCB footprints and reflow profiles are interchangeable.

Q: What does AEC-Q200 qualification mean?

A: AEC-Q200 is an automotive industry standard qualification for passive components. It certifies the component meets reliability and performance requirements for automotive applications. This certification is not required for non-automotive use but indicates enhanced quality documentation.

Q: Are both parts RoHS compliant?

A: Yes. Both ERA-2HEC3090P and ERA-2AEC3090X are ROHS3 compliant and have MSL 1 (unlimited) moisture sensitivity rating.
