ERA-2HEC2002P Equivalent & Substitute Parts

Part Overview

The ERA-2HEC2002P is a 20 kOhms ±0.25% thin film chip resistor in 0402 (1005 Metric) package rated at 0.063W (1/16W). Manufactured by Panasonic Electronic Components, this part is currently obsolete. Due to its discontinued status, equivalent substitute parts with matching electrical and mechanical specifications are necessary to maintain design compatibility and ensure continued component availability for production and repair applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ERA-2HEC2002P is determined by strict equivalence across the following parameters:

• Resistance value: 20 kOhms (exact match required)
• Tolerance: ±0.25% (exact match required)
• Power rating: 0.063W, 1/16W (exact match required)
• Composition: Thin Film (exact match required)
• Package: 0402 (1005 Metric) (exact match required)
• Temperature coefficient: ±25ppm/°C (exact match required)
• RoHS compliance: ROHS3 Compliant (minimum requirement)
• Moisture sensitivity: MSL 1 (exact match required)

The ERA-2AEC2002X meets all these criteria and qualifies as a direct substitute. The ERA-2AEC2002X series differs only in product status (Active vs. Obsolete) and extended operating temperature range (-55°C ~ 155°C vs. -55°C ~ 125°C), representing an enhancement rather than a limitation.

Parameter Comparison

Engineering Selection Recommendations

The ERA-2AEC2002X is the qualified substitute for the obsolete ERA-2HEC2002P. Both parts are manufactured by Panasonic Electronic Components and maintain identical electrical and mechanical specifications across all critical parameters: 20 kOhms resistance, ±0.25% tolerance, 0.063W power rating, thin film composition, and 0402 package.

The ERA-2AEC2002X offers the additional advantage of active product status, ensuring long-term availability and supply chain continuity. The extended operating temperature range (-55°C ~ 155°C) of the ERA-2AEC2002X provides enhanced thermal performance compared to the original part's -55°C ~ 125°C range. Both parts maintain ROHS3 compliance and MSL 1 rating, meeting environmental and moisture handling requirements.

Frequently Asked Questions (FAQ)

Q: Can ERA-2AEC2002X be used as a direct replacement for ERA-2HEC2002P?

A: Yes. Both parts share identical resistance (20 kOhms), tolerance (±0.25%), power rating (0.063W), composition (thin film), package (0402), temperature coefficient (±25ppm/°C), and physical dimensions. The ERA-2AEC2002X is a direct electrical and mechanical substitute.

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

A: The ERA-2H series (ERA-2HEC2002P) is obsolete. The ERA-2A series (ERA-2AEC2002X) is the active equivalent with identical specifications and extended operating temperature range (-55°C ~ 155°C vs. -55°C ~ 125°C).

Q: Are there any compliance or certification differences?

A: Both parts are ROHS3 compliant and carry MSL 1 rating. The ERA-2AEC2002X includes AEC-Q200 automotive qualification, which does not restrict its use in non-automotive applications.

Q: Will the ERA-2AEC2002X fit the same PCB footprint?

A: Yes. Both parts use identical 0402 (1005 Metric) package dimensions: 0.039" L x 0.020" W (1.00mm x 0.50mm) with maximum seated height of 0.016" (0.40mm). PCB layout and assembly processes require no modification.

Q: Is the extended temperature range of ERA-2AEC2002X a concern for standard applications?

A: No. The extended operating range (-55°C ~ 155°C) of the ERA-2AEC2002X is a performance enhancement. Applications operating within the original part's range (-55°C ~ 125°C) will function identically.
