Substitute Part Grouping Explanation

Substitution eligibility for the RG2012P-5900-P-T1 is determined by the following critical parameters:

Primary Matching Criteria:

• Resistance value: 590 Ohms
• Package format: 0805 (2012 Metric)
• Power rating: 0.125W (1/8W) minimum
• Composition: Thin film construction
• Automotive qualification: AEC-Q200
• Operating temperature range: -55°C ~ 155°C minimum
• RoHS3 compliance

Secondary Compatibility Factors:

• Tolerance specification (±0.02% preferred, ±0.1% acceptable with design verification)
• Temperature coefficient performance
• Moisture sensitivity level (MSL 1 or equivalent)
• Product status (active preferred for long-term availability)

Substitute parts must maintain electrical equivalence across all primary criteria. Tolerance and temperature coefficient variations are noted for design consideration but do not preclude substitution where the application permits relaxed specifications.

Engineering Selection Recommendations

RG2012V-5900-P-T1 (Susumu - Upgrade Path)

The RG2012V-5900-P-T1 represents the direct upgrade from the obsolete RG2012P-5900-P-T1. Both components are manufactured by Susumu and share identical electrical specifications: 590 Ohms ±0.02% tolerance, 0.125W power rating, and 0805 package format. The RG2012V variant is currently in active production status, ensuring long-term availability and supply chain continuity. The RG2012V-5900-P-T1 features an improved temperature coefficient of ±5ppm/°C compared to the original ±25ppm/°C specification, providing enhanced thermal stability. Both parts maintain anti-sulfur coating and AEC-Q200 automotive qualification. The primary difference is packaging format: RG2012V-5900-P-T1 is supplied in Tape & Reel format, whereas the original RG2012P-5900-P-T1 was supplied in bulk packaging. This variant is the preferred substitute for direct replacement applications.

ERA-6AEB5900V (Panasonic Electronic Components - Alternative Substitute)

The ERA-6AEB5900V from Panasonic Electronic Components provides functional equivalence with relaxed tolerance specifications. This component maintains the 590 Ohms resistance value, 0.125W power rating, 0805 package format, and AEC-Q200 automotive qualification across the -55°C ~ 155°C operating temperature range. The ERA-6AEB5900V features a tolerance of ±0.1%, which is wider than the original ±0.02% specification. The temperature coefficient is ±25ppm/°C, matching the original part. The seated height is 0.024" (0.60mm) compared to 0.020" (0.50mm) for the original, representing a 0.004" (0.10mm) increase that may require PCB layout verification in space-constrained applications. The ERA-6AEB5900V does not include anti-sulfur coating, though it maintains full AEC-Q200 compliance. This component is in active production with high inventory availability. The ERA-6AEB5900V is suitable for applications where the relaxed tolerance specification is acceptable.

Frequently Asked Questions (FAQ)

Q: Can the RG2012V-5900-P-T1 be used as a direct replacement for the RG2012P-5900-P-T1?

A: Yes. Both components share identical electrical specifications (590 Ohms ±0.02%, 0.125W, 0805 package) and automotive qualifications. The RG2012V-5900-P-T1 is the active production equivalent and is the recommended substitute. The primary difference is packaging format (Tape & Reel versus bulk).

Q: What is the tolerance difference between the RG2012P-5900-P-T1 and ERA-6AEB5900V?

A: The RG2012P-5900-P-T1 specifies ±0.02% tolerance, while the ERA-6AEB5900V specifies ±0.1% tolerance. The ERA-6AEB5900V tolerance is five times wider. Substitution is valid only if the application design permits the relaxed tolerance specification.

Q: Does the ERA-6AEB5900V have anti-sulfur coating?

A: No. The ERA-6AEB5900V does not include anti-sulfur coating, whereas both Susumu RG series parts (RG2012P-5900-P-T1 and RG2012V-5900-P-T1) feature anti-sulfur protection. Applications requiring anti-sulfur coating must use the Susumu variants.

Q: Are there height differences between these components?

A: Yes. The RG2012P-5900-P-T1 and RG2012V-5900-P-T1 have a maximum seated height of 0.020" (0.50mm). The ERA-6AEB5900V has a maximum seated height of 0.024" (0.60mm), representing a 0.004" (0.10mm) increase. PCB layout verification is required if height clearance is critical.

Q: What is the temperature coefficient difference?

A: The RG2012P-5900-P-T1 specifies ±25ppm/°C. The RG2012V-5900-P-T1 specifies ±5ppm/°C, providing superior thermal stability. The ERA-6AEB5900V specifies ±25ppm/°C, matching the original part. Applications requiring minimal temperature drift should prioritize the RG2012V-5900-P-T1.

Q: Are all three components AEC-Q200 qualified?

A: Yes. The RG2012P-5900-P-T1, RG2012V-5900-P-T1, and ERA-6AEB5900V all carry AEC-Q200 automotive qualification and are suitable for automotive applications.

Q: What is the product status of each component?

A: The RG2012P-5900-P-T1 is obsolete. The RG2012V-5900-P-T1 and ERA-6AEB5900V are both in active production, ensuring long-term availability and supply chain support.

Q: Are all components RoHS3 compliant?

A: Yes. The RG2012P-5900-P-T1, RG2012V-5900-P-T1, and ERA-6AEB5900V are all ROHS3 compliant and REACH unaffected.
