RG2012P-4420-B-T5 Equivalent & Substitute Parts

Part Overview

The RG2012P-4420-B-T5 is a 442 Ohm thin film chip resistor manufactured by Susumu, rated at 0.125W (1/8W) power dissipation in an 0805 (2012 Metric) surface mount package. This component is specified for automotive applications with AEC-Q200 qualification and anti-sulfur construction. The part is active in production status with 979 units currently in stock. Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and supply chain continuity for applications requiring 442 Ohm resistors with ±0.1% tolerance in the 0805 package format.

Substitute Part Grouping Explanation

Substitution eligibility for the RG2012P-4420-B-T5 is determined by the following critical parameters:

Primary Substitution Criteria:

• Resistance value: 442 Ohms (exact match required)
• Tolerance: ±0.1% (exact match required)
• Package: 0805 (2012 Metric) (exact match required)
• Composition: Thin Film (exact match required)
• Temperature Coefficient: ±25ppm/°C (exact match required)
• Operating Temperature Range: -55°C ~ 155°C (exact match required)
• RoHS Compliance: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

Secondary Substitution Criteria (Allowable Variation):

• Power Rating: Equal to or greater than 0.125W
• Automotive Rating: AEC-Q200 certification preferred but not mandatory for all applications
• Physical Height: Variation acceptable within assembly constraints

The identified substitute parts meet all primary criteria. Variations in power rating and physical height are acceptable because higher power ratings provide design margin, and height differences remain within standard PCB assembly tolerances for 0805 components.

Parameter Comparison

Engineering Selection Recommendations

RG2012P-4420-B-T5 (Susumu): Primary specification. Active production status. AEC-Q200 automotive qualification with anti-sulfur construction. Recommended for automotive applications requiring full AEC-Q200 compliance and corrosion resistance. Moderate inventory availability.

ERA-6AEB4420V (Panasonic): Direct functional equivalent. Active production status. AEC-Q200 automotive qualification. Identical power rating and physical dimensions to the primary part. Highest inventory availability (17272 units). Suitable for automotive applications with equivalent performance requirements. Recommended as primary substitute due to superior stock levels and matching automotive certification.

8-2176091-4 (TE Connectivity): Functional substitute with increased power rating (0.25W vs. 0.125W). Active production status. No automotive rating specified. Slightly increased physical height (0.026" vs. 0.020"). Suitable for applications where higher power dissipation margin is beneficial and automotive certification is not required. Verify PCB assembly clearance due to increased height.

Frequently Asked Questions (FAQ)

Q: Can the ERA-6AEB4420V replace the RG2012P-4420-B-T5 in automotive applications?

A: Yes. The ERA-6AEB4420V meets all critical electrical parameters (442 Ohms, ±0.1% tolerance, ±25ppm/°C temperature coefficient, -55°C to 155°C operating range) and carries AEC-Q200 automotive qualification identical to the primary part. Physical dimensions are compatible with 0805 package assembly requirements.

Q: What is the difference between the 0.125W and 0.25W power ratings?

A: The RG2012P-4420-B-T5 and ERA-6AEB4420V are rated at 0.125W, while the 8-2176091-4 is rated at 0.25W. In applications where the circuit dissipates less than 0.125W through the resistor, both ratings are functionally equivalent. The 0.25W rating provides additional thermal margin but does not alter electrical performance. Verify actual power dissipation in the application to confirm adequacy of the 0.125W rating.

Q: Are there physical compatibility concerns with the substitute parts?

A: All three parts use the 0805 (2012 Metric) package with identical length (0.079") and width (0.049"). Maximum seated heights vary: RG2012P-4420-B-T5 at 0.020", ERA-6AEB4420V at 0.024", and 8-2176091-4 at 0.026". These variations are within standard PCB assembly tolerances. Verify clearance for components or structures above the resistor if height-constrained.

Q: Which substitute part has the best inventory availability?

A: The ERA-6AEB4420V has the highest inventory level at 17272 units, compared to 979 units for the RG2012P-4420-B-T5 and 708 units for the 8-2176091-4. For applications requiring immediate availability or large-volume procurement, the ERA-6AEB4420V is the preferred choice.

Q: Is the 8-2176091-4 suitable for automotive applications?

A: The 8-2176091-4 meets all electrical specifications and environmental requirements (ROHS3 compliant, MSL 1, -55°C to 155°C operating range). However, it does not carry AEC-Q200 automotive qualification. Use this part only in non-automotive applications or where automotive certification is not a design requirement.

Q: Do all substitute parts have identical tolerance specifications?

A: Yes. All three parts are specified at ±0.1% tolerance, meeting precision requirements for applications demanding tight resistor value accuracy. Temperature coefficient is identical at ±25ppm/°C across all parts.
