Substitute Part Grouping Explanation

Substitution between ERA-1ARB4530C and ERA-1AEB4530C is permissible based on the following matched parameters:

• Resistance value: 453 Ohms (identical)
• Tolerance: ±0.1% (identical)
• Power rating: 0.05W, 1/20W (identical)
• Package type: 0201 (0603 Metric) (identical)
• Composition: Thin Film (identical)
• Operating temperature range: -55°C ~ 155°C (identical)
• Physical dimensions: 0.024" L x 0.012" W, height 0.010" max (identical)
• RoHS compliance: ROHS3 Compliant (identical)
• Moisture sensitivity: MSL 1 (Unlimited) (identical)

The primary difference is the temperature coefficient specification (±10ppm/°C vs. ±25ppm/°C) and product status (obsolete vs. active). Both parameters remain within acceptable substitution criteria for standard applications.

Parameter Comparison

Engineering Selection Recommendations

ERA-1AEB4530C is the direct equivalent for ERA-1ARB4530C applications. The substitute part maintains identical electrical specifications (453 Ohms ±0.1%, 0.05W) and mechanical compatibility (0201 package, identical dimensions). Both components satisfy ROHS3 compliance and MSL 1 requirements.

The ERA-1AEB4530C offers the advantage of active product status, ensuring continued availability and supply chain stability. The temperature coefficient difference (±25ppm/°C vs. ±10ppm/°C) represents a relaxation of the specification; applications requiring the tighter ±10ppm/°C tolerance must evaluate whether the ±25ppm/°C performance is acceptable for the intended circuit function.

Packaging format differs: ERA-1ARB4530C is supplied in standard packaging, while ERA-1AEB4530C is supplied in Tape & Reel (TR) format, which is standard for high-volume manufacturing and automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can ERA-1AEB4530C replace ERA-1ARB4530C in existing designs?

A: Yes. Both components share identical resistance (453 Ohms), tolerance (±0.1%), power rating (0.05W), package type (0201), and operating temperature range (-55°C ~ 155°C). Physical dimensions and termination count are identical, ensuring PCB footprint compatibility.

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

A: ERA-1ARB4530C specifies ±10ppm/°C while ERA-1AEB4530C specifies ±25ppm/°C. This difference affects resistance stability across temperature extremes. Applications with strict temperature-dependent tolerance requirements must evaluate whether the ±25ppm/°C specification meets circuit performance criteria.

Q: Why is ERA-1ARB4530C listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. ERA-1AEB4530C, with active status, represents the current production equivalent and is recommended for new designs and ongoing procurement.

Q: Are there packaging considerations for substitution?

A: ERA-1ARB4530C uses standard packaging while ERA-1AEB4530C uses Tape & Reel (TR) format. TR packaging is standard for automated assembly and high-volume production. Both formats contain identical components; packaging format selection depends on assembly process requirements.

Q: Do both parts meet RoHS and MSL requirements?

A: Yes. Both ERA-1ARB4530C and ERA-1AEB4530C are ROHS3 compliant and rated MSL 1 (Unlimited moisture sensitivity level), indicating no special moisture protection requirements during storage or handling.
