Substitute Part Grouping Explanation

Substitution between ERA-1ARB2100C and ERA-1AEB2100C is based on the following allowed parameters:

• Identical resistance value: 210 Ohms
• Identical tolerance: ±0.1%
• Identical power rating: 0.05W (1/20W)
• Identical composition: Thin Film
• Identical package: 0201 (0603 Metric)
• Identical physical dimensions: 0.024" L x 0.012" W (0.60mm x 0.30mm)
• Identical height: 0.010" (0.26mm) maximum
• Identical operating temperature range: -55°C ~ 155°C
• Identical RoHS3 compliance
• Identical MSL rating: 1 (Unlimited)

The primary difference is the temperature coefficient specification (±10ppm/°C vs. ±25ppm/°C) and product status (obsolete vs. active). Both parts meet the core electrical and mechanical requirements for direct substitution.

Parameter Comparison

Engineering Selection Recommendations

ERA-1AEB2100C is the direct substitute for ERA-1ARB2100C based on the following factors:

• Both parts are ROHS3 compliant and meet identical regulatory requirements
• Both parts carry MSL rating 1 (Unlimited), indicating identical moisture handling requirements
• Both parts are manufactured by Panasonic Electronic Components within the ERA-1A series
• ERA-1AEB2100C maintains active product status, ensuring continued availability and supply chain stability
• Electrical specifications (resistance, tolerance, power rating, operating temperature) are identical
• Physical footprint and dimensions are identical, allowing direct PCB layout compatibility
• The temperature coefficient difference (±10ppm/°C vs. ±25ppm/°C) does not prevent substitution; applications requiring the tighter coefficient specification should be evaluated against circuit performance requirements

Frequently Asked Questions (FAQ)

Q: Can ERA-1AEB2100C be used as a direct replacement for ERA-1ARB2100C?

A: Yes. Both parts share identical electrical specifications (210 Ohms ±0.1%, 0.05W), composition (thin film), package (0201), and operating temperature range (-55°C ~ 155°C). Physical dimensions and compliance certifications are identical.

Q: What is the difference between these two parts?

A: The primary differences are temperature coefficient (±10ppm/°C vs. ±25ppm/°C) and product status (obsolete vs. active). ERA-1AEB2100C is the active production equivalent.

Q: Does the temperature coefficient difference affect substitution?

A: The temperature coefficient specification is provided for reference. Applications requiring the tighter ±10ppm/°C specification should evaluate circuit performance with the ±25ppm/°C tolerance of ERA-1AEB2100C.

Q: Are the packages identical?

A: Yes. Both parts use 0201 package (0603 Metric) with identical dimensions of 0.024" L x 0.012" W (0.60mm x 0.30mm) and maximum height of 0.010" (0.26mm).

Q: What is the packaging format for ERA-1AEB2100C?

A: ERA-1AEB2100C is supplied in Tape & Reel (TR) format.

Q: Are both parts RoHS compliant?

A: Yes. Both ERA-1ARB2100C and ERA-1AEB2100C are ROHS3 compliant.
