ERA-1ARB201C Equivalent & Substitute Parts

Part Overview

The ERA-1ARB201C is a 200 Ohms ±0.1% thin film chip resistor in 0201 (0603 Metric) package format, rated at 0.05W (1/20W) power dissipation. This component is classified as obsolete product status. Due to its obsolete designation, identifying equivalent and substitute parts is necessary to maintain design continuity and ensure component availability for production and repair applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the ERA-1ARB201C is determined by strict equivalence across the following critical parameters:

• Resistance value: 200 Ohms
• Tolerance: ±0.1%
• Power rating: 0.05W (1/20W)
• Package format: 0201 (0603 Metric)
• Composition: Thin Film
• Operating temperature range: -55°C ~ 155°C
• RoHS3 compliance

The ERA-1AEB201C qualifies as a direct substitute based on matching all critical electrical and mechanical specifications. Variations in temperature coefficient (±25ppm/°C versus ±10ppm/°C) and product status (Active versus Obsolete) do not disqualify substitution when the primary functional parameters align.

Parameter Comparison

Engineering Selection Recommendations

The ERA-1AEB201C is the qualified substitute for the obsolete ERA-1ARB201C. Both components are manufactured by Panasonic Electronic Components within the ERA-1A series and maintain identical electrical specifications for resistance, tolerance, and power rating. Both components are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating.

The ERA-1AEB201C offers the advantage of active product status, ensuring continued availability and supply chain reliability. The temperature coefficient difference (±25ppm/°C versus ±10ppm/°C) represents a relaxation of the specification; applications requiring the tighter ±10ppm/°C coefficient should evaluate whether the ±25ppm/°C performance remains acceptable for the intended circuit function.

Frequently Asked Questions (FAQ)

Q: Can ERA-1AEB201C be used as a direct replacement for ERA-1ARB201C in existing designs?

A: Yes. Both components share identical resistance value (200 Ohms), tolerance (±0.1%), power rating (0.05W), package format (0201), and operating temperature range (-55°C ~ 155°C). The primary difference is the temperature coefficient specification and product status. Designs tolerant of ±25ppm/°C temperature coefficient can use ERA-1AEB201C without modification.

Q: What is the significance of the temperature coefficient difference?

A: The ERA-1ARB201C specifies ±10ppm/°C while ERA-1AEB201C specifies ±25ppm/°C. This affects resistance stability across temperature variations. Applications requiring precision matching or tight tolerance maintenance across temperature extremes should evaluate whether the relaxed specification impacts circuit performance.

Q: Are there packaging differences between these parts?

A: Both components use identical 0201 (0603 Metric) package format with matching physical dimensions (0.024" L x 0.012" W, 0.60mm x 0.30mm) and height (0.010" maximum seated height). The ERA-1AEB201C is available in Tape & Reel (TR) packaging, which is standard for production quantities.

Q: Why is ERA-1ARB201C marked as obsolete?

A: Product obsolescence reflects manufacturer lifecycle decisions. The ERA-1AEB201C, as an active product within the same ERA-1A series, provides continuity for applications requiring 200 Ohms ±0.1% thin film resistors in 0201 package format.

Q: Are both parts RoHS compliant?

A: Yes. Both ERA-1ARB201C and ERA-1AEB201C are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, meeting environmental and regulatory requirements for electronic component applications.
