Substitute Part Grouping Explanation

Substitution eligibility for the RG2012P-1580-B-T5 is determined by the following critical parameters:

Primary Matching Criteria:

• Resistance value: 158 Ohms
• Tolerance: ±0.1%
• Package format: 0805 (2012 Metric)
• Composition: Thin Film
• Temperature coefficient: ±25ppm/°C
• Operating temperature range: -55°C ~ 155°C
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

Secondary Compatibility Factors:

• Power rating: Equal or greater than 0.125W
• Automotive qualification: AEC-Q200 (where specified in application requirements)
• Number of terminations: 2
• Physical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm)

Substitute parts are grouped into two categories based on power rating compatibility. Parts with equal or higher power dissipation capacity are electrically and mechanically interchangeable within the specified parameter constraints.

Engineering Selection Recommendations

ERA-6AEB1580V (Panasonic Electronic Components)

The ERA-6AEB1580V is a direct functional equivalent to the RG2012P-1580-B-T5. Both components share identical electrical specifications (158 Ohms, ±0.1%, 0.125W), matching package format (0805), and automotive AEC-Q200 qualification. The Panasonic part is actively produced with high inventory availability (5500 pcs). Physical height difference (0.024" vs. 0.020") is within typical PCB assembly tolerances for 0805 components. This substitute is suitable for applications requiring automotive-grade reliability and AEC-Q200 compliance.

4-2176091-3 (TE Connectivity Passive Product)

The 4-2176091-3 provides electrical equivalence with a higher power rating (0.25W vs. 0.125W). All electrical parameters match the primary part: 158 Ohms, ±0.1% tolerance, ±25ppm/°C temperature coefficient, and -55°C ~ 155°C operating range. The increased power dissipation capacity allows operation in applications with higher thermal stress. This part does not carry explicit AEC-Q200 automotive qualification. Physical height (0.026" max) is slightly elevated compared to the primary part but remains within standard 0805 assembly specifications. Selection of this substitute is appropriate for non-automotive applications or where higher power margin is required.

Frequently Asked Questions (FAQ)

Q: Can ERA-6AEB1580V be used as a direct replacement for RG2012P-1580-B-T5?

A: Yes. Both components have identical resistance (158 Ohms), tolerance (±0.1%), power rating (0.125W), package format (0805), and automotive AEC-Q200 qualification. Physical dimensions are compatible with standard PCB assembly processes.

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

A: The RG2012P-1580-B-T5 and ERA-6AEB1580V are rated for 0.125W (1/8W) power dissipation. The 4-2176091-3 is rated for 0.25W (1/4W). A higher power rating indicates greater thermal capacity and allows operation at higher current levels without exceeding temperature limits. The 0.25W part can be used in applications designed for 0.125W components without performance degradation.

Q: Are all three parts RoHS3 compliant?

A: Yes. The RG2012P-1580-B-T5, ERA-6AEB1580V, and 4-2176091-3 are all ROHS3 compliant.

Q: Does the 4-2176091-3 have automotive qualification?

A: The 4-2176091-3 does not carry explicit AEC-Q200 automotive qualification in the provided specifications. For applications requiring automotive-grade components, the ERA-6AEB1580V is the recommended substitute.

Q: What is the significance of the height difference between these parts?

A: The seated heights are 0.020" (RG2012P-1580-B-T5), 0.024" (ERA-6AEB1580V), and 0.026" (4-2176091-3). These variations are within standard tolerances for 0805 (2012 Metric) package components and do not affect PCB assembly compatibility or electrical performance.

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

A: Yes, provided the application does not exceed the power rating of the selected component. For circuits designed for 0.125W operation, all three parts are suitable. For circuits requiring higher power dissipation, the 4-2176091-3 (0.25W) provides additional thermal margin.

Q: What is the Moisture Sensitivity Level (MSL) rating?

A: All three parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
