Key Parameters

Substitute Part Grouping Explanation

Substitution of the ERA-2HEC1102P is determined by strict equivalence across the following parameters:

• Resistance value: 11 kOhms
• Tolerance: ±0.25%
• Power rating: 0.063W (1/16W)
• Package type: 0402 (1005 Metric)
• Composition: Thin Film
• Temperature coefficient: ±25ppm/°C
• Number of terminations: 2
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

The ERA-2AEC1102X meets all these criteria and qualifies as a direct substitute. The primary distinction is that ERA-2AEC1102X is an active product with automotive AEC-Q200 qualification and an extended upper operating temperature limit of 155°C compared to the 125°C maximum of the obsolete ERA-2HEC1102P.

Parameter Comparison

Engineering Selection Recommendations

The ERA-2AEC1102X is the qualified substitute for the obsolete ERA-2HEC1102P. Both components share identical electrical specifications (11 kOhms ±0.25%, 0.063W, ±25ppm/°C) and mechanical dimensions (0402 package, 1.00mm x 0.50mm). The ERA-2AEC1102X is currently in active production status, ensuring long-term availability and supply chain stability.

The ERA-2AEC1102X carries AEC-Q200 automotive qualification, which provides additional reliability assurance. Its extended operating temperature range (-55°C ~ 155°C versus -55°C ~ 125°C) offers broader thermal performance capability. Both components maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard manufacturing and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can ERA-2AEC1102X be used as a direct replacement for ERA-2HEC1102P?

A: Yes. Both components have identical resistance (11 kOhms), tolerance (±0.25%), power rating (0.063W), package type (0402), composition (thin film), temperature coefficient (±25ppm/°C), and physical dimensions. They are electrically and mechanically interchangeable.

Q: What is the primary difference between these two parts?

A: The ERA-2HEC1102P is obsolete, while the ERA-2AEC1102X is an active product. The ERA-2AEC1102X includes AEC-Q200 automotive qualification and operates at temperatures up to 155°C, compared to 125°C for the ERA-2HEC1102P.

Q: Are there any package or footprint differences?

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 maximum seated height (0.016", 0.40mm). PCB footprints are identical.

Q: Do both parts meet RoHS requirements?

A: Yes. Both ERA-2HEC1102P and ERA-2AEC1102X are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: Why should I select ERA-2AEC1102X over ERA-2HEC1102P?

A: The ERA-2HEC1102P is discontinued. The ERA-2AEC1102X provides equivalent performance with active production status, ensuring availability and supply chain continuity. Its AEC-Q200 qualification and extended temperature range offer additional design margin.
