Key Parameters

Substitute Part Grouping Explanation

Substitution of the ERA-1ARB4320C is determined by strict equivalence across the following critical parameters:

• Resistance value: 432 Ohms (exact match required)
• Tolerance: ±0.1% (precision specification must be maintained)
• Power rating: 0.05W minimum (1/20W)
• Package format: 0201 (0603 Metric) (physical and electrical compatibility)
• Composition: Thin Film (electrical performance characteristics)
• Operating temperature range: -55°C ~ 155°C minimum (environmental compatibility)
• RoHS3 compliance (regulatory requirement)

The ERA-1AEB4320C meets all substitution criteria as an active production alternative within the ERA-1A series from Panasonic Electronic Components.

Parameter Comparison

Engineering Selection Recommendations

The ERA-1AEB4320C is a direct functional equivalent to the obsolete ERA-1ARB4320C. Both components share identical electrical specifications for resistance value, tolerance, power rating, and package format. The substitute part maintains ROHS3 compliance and identical moisture sensitivity classification.

The primary distinction between the two parts is product status: ERA-1ARB4320C is obsolete while ERA-1AEB4320C is in active production. The ERA-1AEB4320C is available in Tape & Reel (TR) packaging, which is standard for production environments.

A secondary difference exists in temperature coefficient specification: ERA-1ARB4320C specifies ±10ppm/°C while ERA-1AEB4320C specifies ±25ppm/°C. For applications where the tighter temperature coefficient of the original part is critical, this parameter difference must be evaluated against circuit performance requirements.

Frequently Asked Questions (FAQ)

Q: Can ERA-1AEB4320C be used as a direct replacement for ERA-1ARB4320C?

A: Yes, for applications where the temperature coefficient specification of ±25ppm/°C is acceptable. Both parts are identical in resistance value (432 Ohms), tolerance (±0.1%), power rating (0.05W), package format (0201), and operating temperature range (-55°C ~ 155°C). The ERA-1AEB4320C is the active production alternative within the ERA-1A series.

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

A: The ERA-1ARB4320C specifies ±10ppm/°C while the ERA-1AEB4320C specifies ±25ppm/°C. This difference affects resistor stability across temperature variations. Applications requiring the tighter specification must evaluate whether the substitute part's ±25ppm/°C performance meets circuit tolerance budgets.

Q: Are the physical dimensions identical?

A: Yes. Both parts are packaged in 0201 (0603 Metric) format with identical dimensions of 0.024" L x 0.012" W (0.60mm x 0.30mm) and maximum seated height of 0.010" (0.26mm). PCB layout compatibility is maintained.

Q: What packaging formats are available?

A: The ERA-1ARB4320C was supplied in standard packaging. The ERA-1AEB4320C is available in Tape & Reel (TR) format, which is standard for automated assembly processes.

Q: Are both parts RoHS compliant?

A: Yes. Both ERA-1ARB4320C and ERA-1AEB4320C are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), meeting current regulatory requirements.
