Key Parameters

Substitute Part Grouping Explanation

Substitution of the ERA-2HEC93R1X is determined by strict equivalence across the following parameters:

• Resistance value: 93.1 Ohms (exact match required)
• Tolerance: ±0.25% (exact match required)
• Power rating: 0.063W minimum
• Package: 0402 (1005 Metric) form factor
• Composition: Thin film construction
• Temperature coefficient: ±25ppm/°C or better
• Operating temperature range: Must support minimum -55°C ~ 125°C
• RoHS compliance: ROHS3 Compliant

The ERA-2AEC93R1X qualifies as a direct substitute based on matching all electrical specifications and package requirements. The primary distinction is product status and thermal operating range extension.

Parameter Comparison

Engineering Selection Recommendations

The ERA-2AEC93R1X is the qualified substitute for the obsolete ERA-2HEC93R1X. Both components share identical electrical specifications (93.1 Ohms ±0.25%, 0.063W, ±25ppm/°C) and mechanical compatibility (0402 package, 1.00mm x 0.50mm x 0.40mm maximum height).

The ERA-2AEC93R1X offers the following advantages:

• Active product status ensures long-term availability and supply chain continuity
• Extended operating temperature range (-55°C ~ 155°C vs. -55°C ~ 125°C) provides thermal margin for demanding applications
• Automotive AEC-Q200 qualification indicates enhanced reliability and quality assurance
• ROHS3 compliance and MSL 1 rating match the original specification

Selection of the ERA-2AEC93R1X is appropriate for all applications previously using the ERA-2HEC93R1X without circuit redesign or thermal derating.

Frequently Asked Questions (FAQ)

Q: Can the ERA-2AEC93R1X be used as a direct replacement for ERA-2HEC93R1X?

A: Yes. Both components have identical resistance (93.1 Ohms), tolerance (±0.25%), power rating (0.063W), temperature coefficient (±25ppm/°C), and 0402 package dimensions. No circuit modifications are required.

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

A: The ERA-2A series incorporates Automotive AEC-Q200 qualification and extends the maximum operating temperature to 155°C. The ERA-2H series is the standard industrial variant with a 125°C maximum operating temperature. Both use identical thin film construction and electrical specifications.

Q: Are there any compatibility concerns with PCB assembly?

A: No. Both parts use the 0402 (1005 Metric) package with identical footprint dimensions (1.00mm x 0.20mm) and maximum seated height (0.40mm). Existing PCB designs and pick-and-place programs require no modification.

Q: Does the AEC-Q200 qualification affect non-automotive applications?

A: No. AEC-Q200 qualification indicates enhanced reliability testing and quality standards. Components meeting automotive standards are suitable for general industrial, consumer, and commercial applications without restriction.

Q: What is the inventory status for these parts?

A: ERA-2HEC93R1X: 843 pieces in stock (obsolete status). ERA-2AEC93R1X: 772 pieces in stock (active product). For new designs and replenishment, source the ERA-2AEC93R1X to ensure continued availability.
