Key Parameters

Substitute Part Grouping Explanation

Substitution of the RG2012N-154-C-T5 is determined by strict equivalence across the following critical parameters:

Mandatory Equivalence Parameters:

• Resistance value: 150 kOhms (exact match required)
• Package / Case: 0805 (2012 Metric) (physical and electrical compatibility)
• Power rating: Minimum 0.125W (1/8W) or higher
• Composition: Thin Film (electrical characteristics and stability)
• Temperature Coefficient: ±10ppm/°C (thermal stability)
• Moisture Sensitivity Level: 1 (Unlimited) (handling and storage compatibility)
• RoHS Status: ROHS3 Compliant (regulatory compliance)

Tolerance Consideration: Substitute parts with equal or tighter tolerance specifications (lower tolerance values) are functionally compatible. The original part specifies ±0.25% tolerance; substitutes with ±0.1% or ±0.05% tolerance provide improved precision while maintaining backward compatibility.

Automotive Qualification: The original part carries AEC-Q200 automotive qualification. Substitute parts either maintain this qualification or provide equivalent reliability certifications suitable for the intended application environment.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Susumu RG Series):

The Susumu RG2012N-154-B-T5, RG2012N-154-W-T1, and RG2012N-154-W-T5 are direct substitutes from the same manufacturer series. All three maintain identical package specifications, thermal characteristics, and automotive AEC-Q200 qualification. The RG2012N-154-B-T5 provides ±0.1% tolerance, while RG2012N-154-W-T1 and RG2012N-154-W-T5 offer superior ±0.05% tolerance. These components are active products with established supply availability.

Secondary Substitutes (Alternative Manufacturers):

The MCU08050F1503BP500 (Vishay Beyschlag) and TNPW0805150KBYEA (Vishay Dale) provide functional equivalence with identical resistance, package, and thin film composition. The MCU08050F1503BP500 operates within a reduced temperature range (-55°C to 125°C) compared to the original specification. The TNPW0805150KBYEA offers enhanced power rating (0.26W) and extended upper operating temperature (175°C), with AEC-Q200 automotive qualification maintained.

Selection Criteria:

For applications requiring strict adherence to the original operating temperature range (-55°C to 155°C) and automotive qualification, select from the Susumu RG series substitutes or the TNPW0805150KBYEA. For applications with reduced thermal requirements, the MCU08050F1503BP500 provides a viable alternative. Tolerance selection should align with circuit precision requirements; tighter tolerance parts (±0.05% or ±0.1%) are backward compatible with the original ±0.25% specification.

Frequently Asked Questions (FAQ)

Q: Can RG2012N-154-B-T5 directly replace RG2012N-154-C-T5?

A: Yes. Both components share identical resistance (150 kOhms), package (0805), power rating (0.125W), composition (thin film), temperature coefficient (±10ppm/°C), operating temperature range (-55°C to 155°C), and AEC-Q200 qualification. The RG2012N-154-B-T5 provides tighter tolerance (±0.1% versus ±0.25%), which is a functional improvement.

Q: What is the difference between RG2012N-154-W-T1 and RG2012N-154-W-T5?

A: Both parts are identical in all electrical and mechanical specifications, including 150 kOhms resistance, ±0.05% tolerance, 0.125W power rating, and 0805 package. The designation difference (T1 versus T5) reflects packaging tape specifications. Both are active products suitable for direct substitution.

Q: Is MCU08050F1503BP500 suitable for applications requiring -55°C to 155°C operation?

A: The MCU08050F1503BP500 operates within -55°C to 125°C range. Applications requiring operation above 125°C must use alternative substitutes such as RG2012N-154-B-T5, RG2012N-154-W-T1, RG2012N-154-W-T5, or TNPW0805150KBYEA.

Q: Does TNPW0805150KBYEA provide advantages over Susumu alternatives?

A: The TNPW0805150KBYEA offers extended upper operating temperature (175°C versus 155°C) and higher power rating (0.26W versus 0.125W). It maintains AEC-Q200 qualification and anti-sulfur construction. Selection depends on whether these enhanced specifications are required for the application.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 Compliant status, matching the original RG2012N-154-C-T5 specification.

Q: Can a ±0.05% tolerance part replace a ±0.25% tolerance part?

A: Yes. Tighter tolerance specifications are functionally compatible with applications designed for looser tolerances. Parts with ±0.05% or ±0.1% tolerance provide improved precision while maintaining backward compatibility with circuits specified for ±0.25% tolerance.

Q: What is the significance of MSL 1 (Unlimited) rating?

A: Moisture Sensitivity Level 1 indicates unlimited shelf life without special moisture control measures. All substitute parts carry this rating, ensuring compatibility with standard storage and handling procedures.

Q: Are there packaging differences between substitute parts?

A: All substitute parts use 0805 (2012 Metric) package with identical footprint dimensions (0.079" L x 0.049" W). Height specifications vary slightly: RG2012N-154-C-T5, RG2012N-154-B-T5, RG2012N-154-W-T1, and RG2012N-154-W-T5 specify 0.020" maximum seated height, while MCU08050F1503BP500 and TNPW0805150KBYEA specify 0.022" maximum. These variations are within standard PCB assembly tolerances.
