ERA-1ARB9760C Equivalent & Substitute Parts

Part Overview

The ERA-1ARB9760C is a 976 Ohm ±0.1% thin film chip resistor in 0201 package (0.60mm x 0.30mm) rated at 0.05W (1/20W) with a temperature coefficient of ±10ppm/°C. This part is classified as obsolete, making identification of equivalent substitute components necessary for ongoing design support and procurement continuity. The ERA-1AEB9760C serves as the direct substitute, offering identical electrical specifications with improved product status and availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ERA-1ARB9760C with the ERA-1AEB9760C is valid based on the following criteria:

• Identical resistance value: 976 Ohms
• Identical tolerance: ±0.1%
• Identical power rating: 0.05W (1/20W)
• Identical composition: Thin Film
• Identical package: 0201 (0603 Metric)
• Identical physical dimensions and height
• Identical operating temperature range: -55°C ~ 155°C
• Identical number of terminations: 2
• Identical RoHS3 compliance and MSL rating

The ERA-1AEB9760C differs only in temperature coefficient (±25ppm/°C vs. ±10ppm/°C) and product status (Active vs. Obsolete). The substitute maintains all critical electrical and mechanical parameters required for direct replacement.

Parameter Comparison

Engineering Selection Recommendations

The ERA-1AEB9760C is the appropriate substitute for the obsolete ERA-1ARB9760C. Both parts are manufactured by Panasonic Electronic Components within the ERA-1A series and maintain ROHS3 compliance and unlimited MSL rating.

The primary distinction is the temperature coefficient specification: the main part specifies ±10ppm/°C while the substitute specifies ±25ppm/°C. This difference must be evaluated against circuit-level tolerance requirements. For applications where the tighter temperature coefficient of the original part is critical, alternative solutions outside the ERA-1A series may be necessary.

The ERA-1AEB9760C is currently in active production status with confirmed inventory availability, providing supply chain continuity for new designs and ongoing production requirements.

Frequently Asked Questions (FAQ)

Q: Can ERA-1AEB9760C be used as a direct replacement for ERA-1ARB9760C?

A: Yes, for applications where the temperature coefficient specification of ±25ppm/°C is acceptable. Both parts share identical resistance, tolerance, power rating, package, and operating temperature range. The ERA-1AEB9760C is the recommended substitute due to active product status and current availability.

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

A: The ERA-1ARB9760C specifies ±10ppm/°C while the ERA-1AEB9760C specifies ±25ppm/°C. This represents a 2.5x difference in temperature stability. Circuit designs requiring the tighter specification must account for this parameter difference.

Q: Are the physical dimensions identical?

A: Yes. Both parts are packaged in 0201 (0603 Metric) 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 and assembly processes are compatible.

Q: What is the packaging difference?

A: The ERA-1ARB9760C is supplied in standard packaging, while the ERA-1AEB9760C is supplied in Tape & Reel (TR) format. Both formats are compatible with standard SMD assembly equipment.

Q: Are both parts RoHS compliant?

A: Yes. Both ERA-1ARB9760C and ERA-1AEB9760C are ROHS3 compliant with MSL rating of 1 (Unlimited), meeting current environmental and regulatory requirements.
