Key Parameters

Substitute Part Grouping Explanation

Substitution for the ERA-2HEC1002P is determined by the following critical parameters:

• Resistance value: 10 kOhms (exact match required)
• Tolerance: ±0.25% (exact match required)
• Power rating: 0.063W, 1/16W (exact match required)
• 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)

The ERA-2AEC1002X meets all these criteria and qualifies as a direct electrical and mechanical substitute. The primary distinction is product status and automotive qualification level.

Parameter Comparison

Engineering Selection Recommendations

The ERA-2AEC1002X is the qualified substitute for the obsolete ERA-2HEC1002P. Both parts are manufactured by Panasonic Electronic Components and share identical electrical specifications: 10 kOhms resistance, ±0.25% tolerance, 0.063W power rating, and thin film composition in 0402 package.

The ERA-2AEC1002X offers extended operating temperature range (-55°C ~ 155°C versus -55°C ~ 125°C) and carries AEC-Q200 automotive qualification. Both parts maintain ROHS3 compliance and MSL 1 rating. The ERA-2AEC1002X is currently in active production status, ensuring supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can ERA-2AEC1002X replace ERA-2HEC1002P in all applications?

A: Yes. Both parts share identical electrical and mechanical specifications: 10 kOhms ±0.25%, 0.063W power rating, thin film composition, and 0402 package. The ERA-2AEC1002X provides equivalent performance with extended temperature range and active product status.

Q: What is the difference between ERA-2HEC and ERA-2AEC series?

A: The ERA-2AEC series includes AEC-Q200 automotive qualification and extended operating temperature range (-55°C ~ 155°C). The ERA-2HEC series operates to -55°C ~ 125°C. Both series use identical thin film technology and tolerance specifications.

Q: Are there any package or footprint differences?

A: No. Both parts 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). PCB footprints are interchangeable.

Q: Is RoHS compliance maintained with the substitute?

A: Yes. Both ERA-2HEC1002P and ERA-2AEC1002X are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: Why is ERA-2HEC1002P obsolete?

A: The ERA-2HEC1002P has been discontinued by Panasonic. The ERA-2AEC1002X remains in active production and serves as the current equivalent for new designs and replacements.
