Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERA-1ARB3480C is determined by the following critical parameters:

• Resistance Value: Must be 348 Ohms
• Tolerance: Must be ±0.1% or tighter
• Power Rating: Must be 0.05W (1/20W) or higher
• Package Type: Must be 0201 (0603 Metric)
• Composition: Must be Thin Film
• Operating Temperature Range: Must cover -55°C ~ 155°C minimum
• Termination Count: Must be 2 terminations
• RoHS Compliance: Must maintain ROHS3 Compliant status

The ERA-1AEB3480C qualifies as a direct substitute, matching all critical electrical and mechanical parameters while offering Active product status and improved procurement availability.

Parameter Comparison

Engineering Selection Recommendations

The ERA-1AEB3480C is the qualified substitute for the obsolete ERA-1ARB3480C. Both components maintain identical electrical specifications (348 Ohms ±0.1%, 0.05W) and mechanical compatibility (0201 package, 0.60mm x 0.30mm footprint). The substitute part offers the advantage of Active product status, ensuring long-term availability and supply chain continuity.

The primary difference is the temperature coefficient specification: ERA-1ARB3480C features ±10ppm/°C while ERA-1AEB3480C features ±25ppm/°C. Both values remain within acceptable ranges for standard industrial applications across the -55°C ~ 155°C operating window. Applications requiring the tighter ±10ppm/°C specification should evaluate whether the ±25ppm/°C performance of the substitute meets circuit requirements.

Both parts maintain ROHS3 Compliance and MSL 1 (Unlimited) ratings, supporting deployment in standard manufacturing environments without moisture sensitivity constraints.

Frequently Asked Questions (FAQ)

Q: Can ERA-1AEB3480C directly replace ERA-1ARB3480C in existing designs?

A: Yes. Both parts share identical resistance (348 Ohms), tolerance (±0.1%), power rating (0.05W), package type (0201), and operating temperature range (-55°C ~ 155°C). Physical footprint and electrical performance are equivalent for standard circuit applications.

Q: What is the difference in temperature coefficient between these parts?

A: ERA-1ARB3480C specifies ±10ppm/°C while ERA-1AEB3480C specifies ±25ppm/°C. The substitute exhibits wider temperature-dependent resistance variation. Designs sensitive to temperature drift should evaluate whether the ±25ppm/°C specification remains acceptable for the intended application.

Q: Does packaging format affect substitution?

A: ERA-1ARB3480C uses standard packaging while ERA-1AEB3480C is supplied in Tape & Reel (TR) format. Both contain identical components; packaging format affects procurement and assembly processes only, not electrical or mechanical performance.

Q: Are both parts RoHS compliant?

A: Yes. Both ERA-1ARB3480C and ERA-1AEB3480C are ROHS3 Compliant with MSL 1 (Unlimited) moisture sensitivity ratings, supporting standard manufacturing and storage conditions.

Q: Why is ERA-1ARB3480C classified as Obsolete?

A: Obsolete status indicates the part is no longer in active production. ERA-1AEB3480C, classified as Active, represents the current production equivalent within the ERA-1A series and is the recommended substitute for new designs and ongoing procurement.
