Substitute Part Grouping Explanation

Substitute parts for the ERA-2HEC1502P must meet the following electrical and mechanical criteria:

• Resistance value: 15 kOhms
• Tolerance: ±0.25%
• Power rating: 0.063W (1/16W) minimum
• Package: 0402 (1005 Metric)
• Composition: Thin Film
• Temperature coefficient: ±25ppm/°C
• Physical dimensions: 0.039" L x 0.020" W (1.00mm x 0.50mm), height ≤ 0.016" (0.40mm)
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

The ERA-2AEC1502X qualifies as a direct substitute based on matching all electrical specifications and package requirements. The primary distinction is product status and operating temperature range extension.

Parameter Comparison

Engineering Selection Recommendations

The ERA-2AEC1502X is a qualified substitute for the ERA-2HEC1502P. Both parts share identical electrical specifications, package dimensions, and compliance certifications. The ERA-2AEC1502X carries active product status and includes AEC-Q200 automotive qualification, providing enhanced availability and extended operating temperature range (-55°C to 155°C versus -55°C to 125°C). Selection of the ERA-2AEC1502X eliminates obsolescence risk while maintaining full electrical and mechanical compatibility with designs specified for the ERA-2HEC1502P.

Frequently Asked Questions (FAQ)

Q: Can ERA-2AEC1502X replace ERA-2HEC1502P in existing designs?

A: Yes. Both parts are 15 kOhms ±0.25% thin film resistors in 0402 package with identical electrical characteristics, temperature coefficient, power rating, and physical dimensions. Electrical and mechanical compatibility is confirmed.

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 to 155°C. The ERA-2H series operates to 125°C. Both series use identical thin film technology and meet the same tolerance and temperature coefficient specifications.

Q: Are there any compliance differences?

A: Both parts are ROHS3 compliant with MSL rating 1 (Unlimited). The ERA-2AEC1502X includes REACH Unaffected status. No compliance barriers exist for substitution.

Q: Does package compatibility require verification?

A: No. Both parts use identical 0402 (1005 Metric) package with matching footprint dimensions (0.039" L x 0.020" W) and maximum seated height (0.016"). PCB layout and assembly processes require no modification.

Q: Is the extended temperature range of ERA-2AEC1502X a concern for standard applications?

A: No. The extended range (-55°C to 155°C) is a superset of the original specification (-55°C to 125°C). Applications operating within the original temperature range experience no adverse effects from the substitute part's broader capability.
