ERA-2HEC4870P Equivalent & Substitute Parts

Part Overview

The ERA-2HEC4870P is a 487 Ohms ±0.25% thin film chip resistor in 0402 (1005 Metric) package rated at 0.063W (1/16W). Manufactured by Panasonic Electronic Components, this component is classified as obsolete. Due to its discontinued status, identifying equivalent substitute parts with matching electrical and mechanical specifications is essential for design continuity and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERA-2HEC4870P is determined by the following critical parameters:

• Resistance Value: 487 Ohms (exact match required)
• Tolerance: ±0.25% (precision specification)
• Power Rating: 0.063W, 1/16W (electrical stress rating)
• Package Type: 0402 (1005 Metric) (physical and footprint compatibility)
• Composition: Thin Film (performance characteristics)
• Temperature Coefficient: ±25ppm/°C (thermal stability)
• RoHS Compliance: ROHS3 Compliant (regulatory requirement)

The ERA-2AEC4870X meets all these criteria and qualifies as a direct substitute. The primary distinction is the addition of AEC-Q200 automotive qualification and an extended upper operating temperature limit of 155°C versus 125°C in the original part.

Parameter Comparison

Engineering Selection Recommendations

The ERA-2AEC4870X is a qualified substitute for the obsolete ERA-2HEC4870P. Both components share identical electrical specifications (487 Ohms, ±0.25% tolerance, 0.063W power rating) and physical packaging (0402 1005 Metric). Both maintain the same temperature coefficient (±25ppm/°C) and RoHS3 compliance status.

The ERA-2AEC4870X offers two advantages: it is currently in active production status, ensuring long-term availability, and it includes AEC-Q200 automotive qualification with an extended operating temperature range to 155°C. These enhancements do not compromise compatibility with applications designed for the original ERA-2HEC4870P.

Selection of the ERA-2AEC4870X eliminates obsolescence risk while maintaining full electrical and mechanical interchangeability.

Frequently Asked Questions (FAQ)

Q: Can the ERA-2AEC4870X be used as a direct replacement for ERA-2HEC4870P?

A: Yes. Both parts share identical resistance (487 Ohms), tolerance (±0.25%), power rating (0.063W), package (0402), composition (thin film), and temperature coefficient (±25ppm/°C). The ERA-2AEC4870X is electrically and mechanically interchangeable.

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

A: The ERA-2A series includes AEC-Q200 automotive qualification and operates to 155°C maximum, compared to 125°C for the ERA-2H series. Both series use identical thin film technology and meet ROHS3 compliance.

Q: Does the extended temperature range of ERA-2AEC4870X affect compatibility?

A: No. The extended range (to 155°C) is an enhancement that does not reduce compatibility. Applications operating within the original -55°C to 125°C range remain fully compatible.

Q: Are both parts RoHS compliant?

A: Yes. Both ERA-2HEC4870P and ERA-2AEC4870X are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level.

Q: Why is ERA-2HEC4870P listed as obsolete?

A: The ERA-2HEC4870P has been discontinued by Panasonic. The ERA-2AEC4870X represents the active production equivalent with enhanced specifications and automotive qualification.
