Substitute Part Grouping Explanation

Substitution of the ERA-2HEC95R3P is determined by the following critical parameters:

• Resistance value: 95.3 Ohms (exact match required)
• Tolerance: ±0.25% (precision class requirement)
• 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 -55°C minimum; upper limit may extend beyond 125°C
• RoHS compliance: ROHS3 Compliant
• MSL rating: 1 or better

The ERA-2AEC95R3X qualifies as a direct substitute based on matching all critical electrical and mechanical parameters while offering extended operating temperature range (-55°C to 155°C) and automotive-grade qualification (AEC-Q200).

Parameter Comparison

Engineering Selection Recommendations

The ERA-2AEC95R3X is a qualified substitute for the obsolete ERA-2HEC95R3P. Both parts share identical electrical specifications (95.3 Ohms ±0.25%, 0.063W, ±25ppm/°C) and mechanical form factor (0402 package).

The ERA-2AEC95R3X offers the following advantages:

• Active product status ensures ongoing availability and supply chain support
• Extended operating temperature range (-55°C to 155°C) provides thermal margin beyond the original part specification
• AEC-Q200 automotive qualification provides additional reliability assurance
• ROHS3 compliance and MSL 1 rating match the original part

For applications operating within the original temperature range (-55°C to 125°C), the ERA-2AEC95R3X provides direct functional equivalence with improved long-term availability.

Frequently Asked Questions (FAQ)

Q: Can the ERA-2AEC95R3X be used as a direct replacement for ERA-2HEC95R3P?

A: Yes. Both parts have identical resistance (95.3 Ohms), tolerance (±0.25%), power rating (0.063W), package (0402), and temperature coefficient (±25ppm/°C). The ERA-2AEC95R3X is pin-compatible and electrically equivalent.

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 to 155°C) compared to the ERA-2H series (-55°C to 125°C). Both use identical thin film construction and tolerance specifications.

Q: Does the extended temperature range of ERA-2AEC95R3X affect circuit performance?

A: No. The extended temperature range indicates the part is qualified to operate reliably at higher temperatures. For applications within the original -55°C to 125°C range, performance characteristics remain identical.

Q: Are there any PCB layout or assembly considerations when substituting ERA-2AEC95R3X for ERA-2HEC95R3P?

A: No. Both parts use the same 0402 (1005 Metric) package with identical dimensions (0.039" L x 0.020" W, 1.00mm x 0.50mm) and height (0.016" maximum). No PCB redesign or assembly process changes are required.

Q: What is the MSL rating and why does it matter?

A: Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity. These parts can be stored indefinitely without special moisture control measures and do not require baking before reflow soldering.

Q: Are both parts RoHS compliant?

A: Yes. Both ERA-2HEC95R3P and ERA-2AEC95R3X are ROHS3 compliant, meeting current environmental and regulatory requirements for electronic components.
