Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERA-2HEB4530X is determined by the following critical parameters:

• Resistance Value: Must be 453 Ohms
• Tolerance: Must be ±0.1% or tighter
• Power Rating: Must be 0.063W (1/16W) or higher
• Package: Must be 0402 (1005 Metric)
• Composition: Must be thin film construction
• Temperature Coefficient: Must be ±25ppm/°C or better
• Operating Temperature Range: Must support minimum -55°C ~ 125°C
• RoHS Compliance: Must maintain ROHS3 compliance

The ERA-2AEB4530X qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. The ERA-2AEB series extends the upper operating temperature to 155°C and includes AEC-Q200 automotive qualification, providing enhanced reliability for automotive applications while maintaining full compatibility with the original specification.

Parameter Comparison

Engineering Selection Recommendations

The ERA-2AEB4530X is the primary substitute for the obsolete ERA-2HEB4530X. Both components are manufactured by Panasonic Electronic Components and share identical electrical specifications and package dimensions. The ERA-2AEB4530X maintains active product status, ensuring continued availability and supply chain support.

The ERA-2AEB4530X provides an extended operating temperature range (-55°C ~ 155°C versus -55°C ~ 125°C) and includes AEC-Q200 automotive qualification. These enhancements do not compromise compatibility with applications designed for the ERA-2HEB4530X; they represent functional improvements suitable for both general industrial and automotive applications.

Selection of the ERA-2AEB4530X is appropriate for new designs, production continuity, and field replacements where the original ERA-2HEB4530X is no longer available.

Frequently Asked Questions (FAQ)

Q: Can the ERA-2AEB4530X be used as a direct replacement for the ERA-2HEB4530X?

A: Yes. Both components share identical resistance value (453 Ohms), tolerance (±0.1%), power rating (0.063W), package (0402), composition (thin film), and temperature coefficient (±25ppm/°C). The ERA-2AEB4530X meets or exceeds all electrical and mechanical requirements of the ERA-2HEB4530X.

Q: What is the difference between the ERA-2HEB and ERA-2AEB series?

A: The ERA-2AEB series includes AEC-Q200 automotive qualification and extends the upper operating temperature limit to 155°C, compared to 125°C for the ERA-2HEB series. Both series maintain identical core electrical specifications and 0402 package dimensions.

Q: Are there any compatibility concerns when substituting the ERA-2AEB4530X?

A: No compatibility concerns exist. The ERA-2AEB4530X is mechanically and electrically interchangeable with the ERA-2HEB4530X. PCB footprints, soldering requirements, and circuit performance remain unchanged.

Q: Why is the ERA-2HEB4530X classified as obsolete?

A: Product obsolescence reflects manufacturer discontinuation decisions. The ERA-2AEB4530X provides an active, supported alternative with enhanced specifications and automotive qualification.

Q: What packaging options are available for the ERA-2AEB4530X?

A: The ERA-2AEB4530X is supplied in Tape & Reel (TR) packaging. Inventory availability is 10,045 pieces in new original condition.
