ERA-1ARB7870C Equivalent & Substitute Parts

Part Overview

The ERA-1ARB7870C is a 787 Ohms ±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 component is classified as obsolete, which necessitates identification of equivalent substitute parts for ongoing design support and procurement continuity. The part maintains ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1), making it suitable for industrial and commercial applications across the -55°C to 155°C operating temperature range.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERA-1ARB7870C is determined by the following critical parameters:

• Resistance value: 787 Ohms (exact match required)
• Tolerance: ±0.1% (exact match required)
• Power rating: 0.05W / 1/20W (exact match required)
• Package: 0201 (0603 Metric) (exact match required)
• Composition: Thin Film (exact match required)
• Operating temperature range: -55°C ~ 155°C (minimum requirement)
• RoHS compliance: ROHS3 (minimum requirement)

The ERA-1AEB7870C meets all substitution criteria. Variations in temperature coefficient (±25ppm/°C vs. ±10ppm/°C) and product status do not disqualify substitution when the primary electrical and mechanical parameters remain identical.

Parameter Comparison

Engineering Selection Recommendations

The ERA-1AEB7870C is a direct functional equivalent to the ERA-1ARB7870C. Both parts are manufactured by Panasonic Electronic Components and share identical electrical specifications (787 Ohms ±0.1%, 0.05W), mechanical dimensions (0201 package), and compliance certifications (ROHS3, MSL 1).

The primary distinction is product status: the ERA-1ARB7870C is obsolete while the ERA-1AEB7870C is active. The ERA-1AEB7870C is the recommended selection for new designs and ongoing procurement due to its active status and confirmed availability. The temperature coefficient difference (±25ppm/°C vs. ±10ppm/°C) reflects manufacturing process variations within the same product family and does not affect substitution eligibility when both parts meet the application's thermal stability requirements.

Frequently Asked Questions (FAQ)

Q: Can ERA-1AEB7870C replace ERA-1ARB7870C in existing designs?

A: Yes. Both parts are identical in resistance value (787 Ohms), tolerance (±0.1%), power rating (0.05W), package (0201), and operating temperature range (-55°C ~ 155°C). Electrical and mechanical compatibility is complete.

Q: What is the difference between ERA-1ARB7870C and ERA-1AEB7870C?

A: The parts differ in temperature coefficient (±10ppm/°C vs. ±25ppm/°C) and product status (obsolete vs. active). The ERA-1AEB7870C represents the current production variant and is the preferred choice for new applications.

Q: Are there packaging differences between these parts?

A: Both parts use 0201 (0603 Metric) packaging with identical dimensions (0.024" L x 0.012" W, 0.60mm x 0.30mm) and maximum seated height (0.010" / 0.26mm). The ERA-1AEB7870C is available in Tape & Reel (TR) packaging, which is standard for production environments.

Q: Do both parts meet RoHS requirements?

A: Yes. Both ERA-1ARB7870C and ERA-1AEB7870C are ROHS3 compliant and carry unlimited moisture sensitivity rating (MSL 1), meeting environmental and reliability standards for industrial applications.

Q: Which part should be specified for new designs?

A: The ERA-1AEB7870C should be specified for new designs. As an active product with confirmed availability and identical electrical performance, it provides supply chain continuity and design support.
