Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RG2012P-621-P-T1 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 620 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 to 155°C minimum
• RoHS compliance: ROHS3 Compliant

Allowable Variation Parameters:

• Tolerance: ±0.02% or wider (±0.1% acceptable for less stringent applications)
• Temperature coefficient: ±5ppm/°C to ±25ppm/°C
• Packaging format: Tape & Reel (TR) acceptable as functional equivalent to standard packaging
• Anti-sulfur feature: Present or absent (feature enhancement does not preclude substitution)

Substitute parts must satisfy all mandatory matching parameters. Variations in tolerance and temperature coefficient represent trade-offs between precision and availability.

Engineering Selection Recommendations

RG2012V-621-P-T1 (Susumu - Upgrade Path)

The RG2012V-621-P-T1 is the primary substitute for the obsolete RG2012P-621-P-T1. Both components are manufactured by Susumu and share identical electrical specifications: 620 Ohms ±0.02% tolerance, 0.125W power rating, and 0805 package format. The RG2012V-621-P-T1 offers superior temperature stability with ±5ppm/°C coefficient compared to ±25ppm/°C of the original part. Both components maintain AEC-Q200 automotive qualification, ROHS3 compliance, and anti-sulfur coating. The RG2012V-621-P-T1 is currently in active production status with higher inventory availability (1125 Pcs vs. 769 Pcs). This component is the direct functional replacement.

ERA-6AEB621V (Panasonic - Alternative Substitute)

The ERA-6AEB621V from Panasonic Electronic Components serves as an alternative substitute when RG2012V-621-P-T1 availability is constrained. This component maintains the same 620 Ohms resistance, 0.125W power rating, 0805 package format, and AEC-Q200 automotive qualification. The tolerance specification is ±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. The ERA-6AEB621V lacks the anti-sulfur feature present in the Susumu variants. This component is suitable for applications where the relaxed tolerance and absence of anti-sulfur coating are acceptable trade-offs. Panasonic ERA-6AEB621V inventory is significantly higher at 15987 Pcs.

Frequently Asked Questions (FAQ)

Q: Can the RG2012V-621-P-T1 be used as a direct replacement for the RG2012P-621-P-T1?

A: Yes. Both components share identical resistance (620 Ohms), tolerance (±0.02%), power rating (0.125W), package format (0805), composition (thin film), operating temperature range (-55°C to 155°C), and AEC-Q200 automotive qualification. The RG2012V-621-P-T1 provides improved temperature stability (±5ppm/°C vs. ±25ppm/°C) and is in active production status.

Q: What is the tolerance difference between the RG2012V-621-P-T1 and ERA-6AEB621V?

A: The RG2012V-621-P-T1 maintains ±0.02% tolerance, identical to the original RG2012P-621-P-T1. The ERA-6AEB621V has ±0.1% tolerance, which is five times wider. Selection between these components depends on circuit precision requirements.

Q: Does the height difference between RG2012V-621-P-T1 and ERA-6AEB621V affect PCB layout?

A: The RG2012V-621-P-T1 has a maximum seated height of 0.020" (0.50mm), while the ERA-6AEB621V is 0.024" (0.60mm). This 0.004" (0.10mm) difference is negligible for most applications but should be verified for designs with tight vertical clearance constraints.

Q: Is the anti-sulfur feature critical for substitution?

A: The anti-sulfur feature is present in both Susumu variants (RG2012P-621-P-T1 and RG2012V-621-P-T1) but absent in the Panasonic ERA-6AEB621V. This feature provides enhanced reliability in sulfur-rich environments. Applications requiring anti-sulfur protection should prioritize Susumu components.

Q: Are all three components AEC-Q200 qualified?

A: Yes. The RG2012P-621-P-T1, RG2012V-621-P-T1, and ERA-6AEB621V all carry AEC-Q200 automotive qualification and are suitable for automotive applications.

Q: What is the packaging difference between the main part and substitutes?

A: The RG2012P-621-P-T1 original packaging format is not specified in the provided data. The RG2012V-621-P-T1 and ERA-6AEB621V are supplied in Tape & Reel (TR) format. Both packaging formats are compatible for automated assembly processes.

Q: Are all components RoHS3 compliant?

A: Yes. The RG2012P-621-P-T1, RG2012V-621-P-T1, and ERA-6AEB621V are all ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited).
