Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERA-2HEC75R0X is determined by the following critical parameters:

• Resistance value: 75 Ohms (exact match required)
• Tolerance: ±0.25% (exact match required)
• Power rating: 0.063W minimum (equal or higher acceptable)
• Package: 0402 (1005 Metric) (exact match required)
• Composition: Thin Film (exact match required)
• Temperature coefficient: ±25ppm/°C (exact match required)
• RoHS compliance: ROHS3 Compliant (minimum requirement)
• Moisture sensitivity: MSL 1 or better (equal or better acceptable)

The ERA-2AEC75R0X meets all substitution criteria while offering enhanced operating temperature range and automotive-grade qualification.

Parameter Comparison

Engineering Selection Recommendations

The ERA-2AEC75R0X is a direct functional substitute for the obsolete ERA-2HEC75R0X. Both components share identical electrical specifications (75 Ohms ±0.25%, 0.063W, ±25ppm/°C) and mechanical dimensions (0402 package). The ERA-2AEC75R0X offers the following advantages:

• Active product status ensures ongoing availability and supply chain continuity
• Extended operating temperature range (-55°C ~ 155°C vs. -55°C ~ 125°C) provides broader application flexibility
• Automotive AEC-Q200 qualification adds reliability assurance for demanding environments
• ROHS3 compliance and MSL 1 rating match the original specification

Selection of the ERA-2AEC75R0X eliminates obsolescence risk while maintaining full electrical and mechanical compatibility with the original design.

Frequently Asked Questions (FAQ)

Q: Can ERA-2AEC75R0X be used as a direct replacement for ERA-2HEC75R0X?

A: Yes. Both components have identical resistance (75 Ohms), tolerance (±0.25%), power rating (0.063W), package (0402), composition (thin film), and temperature coefficient (±25ppm/°C). The ERA-2AEC75R0X is electrically and mechanically compatible with no design modifications required.

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

A: The ERA-2H series is a standard thin film resistor line, while the ERA-2A series is automotive-grade with AEC-Q200 qualification. The ERA-2A series also features an extended operating temperature range (-55°C ~ 155°C compared to -55°C ~ 125°C).

Q: Are the physical dimensions identical?

A: Yes. Both components use the 0402 (1005 Metric) package with identical dimensions: 0.039" L x 0.020" W (1.00mm x 0.50mm) and maximum seated height of 0.016" (0.40mm).

Q: Does the extended temperature range of ERA-2AEC75R0X 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. The extended range provides additional margin for high-temperature applications.

Q: Are both components RoHS compliant?

A: Yes. Both ERA-2HEC75R0X and ERA-2AEC75R0X are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level.
