Substitute Part Grouping Explanation

Substitution eligibility for the RG2012P-2943-B-T5 is determined by the following critical parameters:

Primary Substitution Criteria:

• Resistance value: 294 kOhms (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 qualification preferred but not mandatory for all applications
• Physical dimensions: Allowable variation within 0805 package specification limits

The identified substitute parts meet all primary criteria. The TE Connectivity part (3-2176094-8) provides increased power rating (0.25W) while maintaining all other specifications. The Panasonic part (ERA-6AEB2943V) provides an exact specification match with identical power rating and automotive qualification.

Parameter Comparison

Engineering Selection Recommendations

RG2012P-2943-B-T5 (Susumu) - Primary Selection

This part is the specified component with active production status and automotive AEC-Q200 qualification. It provides the lowest seated height (0.50mm) among the three options and carries REACH Unaffected status. Selection is appropriate for applications with space constraints and automotive compliance requirements.

ERA-6AEB2943V (Panasonic) - Direct Equivalent

This part provides an exact specification match to the primary component, including identical power rating (0.125W), automotive AEC-Q200 qualification, and REACH Unaffected status. The seated height (0.60mm) remains within 0805 package tolerances. This part is suitable for direct substitution with 14,461 units in stock, providing superior inventory availability.

3-2176094-8 (TE Connectivity) - Higher Power Rating Alternative

This part maintains all critical electrical specifications but provides increased power rating (0.25W versus 0.125W). The seated height (0.65mm) is within 0805 package specification limits. This part lacks specified automotive AEC-Q200 qualification and carries undefined REACH status. Selection is appropriate for applications requiring higher power dissipation capability where automotive qualification is not mandatory.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 3-2176094-8 be used as a direct replacement for the Susumu RG2012P-2943-B-T5?

A: The TE Connectivity part is electrically compatible for applications where the increased power rating (0.25W versus 0.125W) does not create design conflicts. However, the TE Connectivity part lacks specified automotive AEC-Q200 qualification. Applications requiring automotive compliance should use the Panasonic ERA-6AEB2943V or remain with the Susumu part.

Q: What is the significance of the seated height differences among these three parts?

A: The seated heights are 0.50mm (Susumu), 0.60mm (Panasonic), and 0.65mm (TE Connectivity). All values remain within 0805 package specification limits. Applications with tight vertical clearance constraints should prioritize the Susumu part. The Panasonic part provides a practical middle ground with minimal height increase.

Q: Are all three parts suitable for automotive applications?

A: The Susumu RG2012P-2943-B-T5 and Panasonic ERA-6AEB2943V both carry AEC-Q200 automotive qualification. The TE Connectivity 3-2176094-8 does not specify automotive qualification. For automotive applications, use either the Susumu or Panasonic parts.

Q: What is the difference between REACH Unaffected and Vendor Undefined status?

A: REACH Unaffected indicates the manufacturer has confirmed the part is not subject to REACH regulations. Vendor Undefined indicates the manufacturer has not provided REACH status information. For applications requiring confirmed REACH compliance documentation, use the Susumu or Panasonic parts.

Q: Can these parts be used interchangeably in the same circuit board design?

A: Yes, all three parts share identical resistance (294 kOhms), tolerance (±0.1%), package (0805), composition (thin film), and temperature coefficient (±25ppm/°C). The 0805 package footprint is identical across all three parts. Physical height differences are within package tolerances and do not affect PCB layout compatibility.

Q: Which part should be selected for new design implementation?

A: For new designs, the Panasonic ERA-6AEB2943V is recommended due to exact specification match with the primary part, automotive AEC-Q200 qualification, REACH Unaffected status, and superior inventory availability (14,461 units). The Susumu RG2012P-2943-B-T5 remains the specified component and is appropriate for designs already qualified to this part number.
