Key Parameters

Substitute Part Grouping Explanation

Substitution of the RG2012P-511-P-T1 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 510 Ohms
• Package format: 0805 (2012 Metric)
• Power rating: 0.125W (1/8W)
• Composition: Thin Film
• Operating temperature range: -55°C ~ 155°C
• Automotive qualification: AEC-Q200
• RoHS compliance: ROHS3 Compliant

Allowable Variation Parameters:

• Tolerance: Substitutes with equal or tighter tolerance (±0.02% or better) are direct equivalents; substitutes with relaxed tolerance (±0.1%) are functional alternatives
• Temperature coefficient: Variation permitted based on application requirements
• Packaging format: Tape & Reel (TR) is compatible with the original packaging specification
• Anti-sulfur feature: Present in primary equivalent; absent in secondary alternative

The RG2012V-511-P-T1 qualifies as a direct upgrade equivalent. The ERA-6AEB511V qualifies as a functional alternative with relaxed tolerance specification.

Parameter Comparison

Engineering Selection Recommendations

RG2012V-511-P-T1 (Susumu) - Primary Equivalent:

The RG2012V-511-P-T1 is the recommended direct replacement for the obsolete RG2012P-511-P-T1. This part maintains identical electrical specifications including 510 Ohm resistance, ±0.02% tolerance, and 0.125W power rating. Both components share the same 0805 package format, thin film composition, and AEC-Q200 automotive qualification. The RG2012V-511-P-T1 offers improved temperature coefficient performance (±5ppm/°C versus ±25ppm/°C) and is currently in active production status. The component retains the anti-sulfur feature and ROHS3 compliance of the original part. Mechanical compatibility is confirmed with identical seated height specifications.

ERA-6AEB511V (Panasonic Electronic Components) - Functional Alternative:

The ERA-6AEB511V serves as a functional alternative when the primary equivalent is unavailable. This Panasonic component maintains the same 510 Ohm resistance, 0.125W power rating, 0805 package format, and AEC-Q200 automotive qualification. The tolerance specification is relaxed to ±0.1%, which is acceptable for applications where the original ±0.02% tolerance is not a critical design requirement. The temperature coefficient matches the original part at ±25ppm/°C. The ERA-6AEB511V lacks the anti-sulfur coating feature present in the Susumu alternatives. The seated height is 0.024" (0.60mm), which is 0.004" greater than the original specification. This component is in active production with substantial inventory availability.

Frequently Asked Questions (FAQ)

Q: Can the RG2012V-511-P-T1 be used as a direct replacement for the RG2012P-511-P-T1?

A: Yes. The RG2012V-511-P-T1 is a direct equivalent. Both parts share identical resistance (510 Ohms), tolerance (±0.02%), power rating (0.125W), package format (0805), composition (thin film), operating temperature range (-55°C ~ 155°C), and AEC-Q200 automotive qualification. The RG2012V-511-P-T1 is in active production status, addressing the obsolescence of the original part.

Q: What is the key difference between the RG2012V-511-P-T1 and ERA-6AEB511V?

A: The primary difference is tolerance specification. The RG2012V-511-P-T1 maintains ±0.02% tolerance matching the original part, while the ERA-6AEB511V has ±0.1% tolerance. Additionally, the RG2012V-511-P-T1 includes anti-sulfur coating; the ERA-6AEB511V does not. Both parts are electrically and mechanically compatible in the 0805 package format with identical power ratings and operating temperature ranges.

Q: Is the ERA-6AEB511V suitable for applications requiring ±0.02% tolerance?

A: No. The ERA-6AEB511V tolerance specification of ±0.1% does not meet the ±0.02% requirement of the original part. Applications with strict tolerance requirements must use the RG2012V-511-P-T1 or equivalent parts with ±0.02% or tighter tolerance.

Q: Are there mechanical compatibility concerns with the ERA-6AEB511V?

A: The ERA-6AEB511V has a maximum seated height of 0.024" (0.60mm) compared to 0.020" (0.50mm) for the original part. This 0.004" difference may affect applications with strict height constraints or high-density PCB layouts. The RG2012V-511-P-T1 maintains the original height specification.

Q: Do all three parts meet automotive qualification requirements?

A: Yes. The RG2012P-511-P-T1, RG2012V-511-P-T1, and ERA-6AEB511V all carry AEC-Q200 automotive qualification and are ROHS3 compliant. All three parts are suitable for automotive applications within their specified operating temperature range of -55°C ~ 155°C.

Q: What is the significance of the anti-sulfur feature?

A: The anti-sulfur coating is present in both Susumu parts (RG2012P-511-P-T1 and RG2012V-511-P-T1) but absent in the Panasonic ERA-6AEB511V. This feature provides enhanced resistance to sulfur-containing environments. Applications in sulfur-prone environments should prioritize the Susumu alternatives.

Q: Can the RG2012V-511-P-T1 be used in place of the ERA-6AEB511V?

A: Yes. The RG2012V-511-P-T1 is electrically and mechanically superior, offering tighter tolerance (±0.02% versus ±0.1%), anti-sulfur coating, and identical package compatibility. The RG2012V-511-P-T1 is the preferred choice when available.
