Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RG2012N-1580-P-T1 is determined by the following critical parameters:

Primary Substitution Criteria:

• Resistance value: 158 Ohms (exact match required)
• Package type: 0805 (2012 Metric) (exact match required)
• Power rating: 0.125W minimum (1/8W)
• Composition: Thin film technology
• Automotive qualification: AEC-Q200 compliance
• Operating temperature range: -55°C to 155°C minimum
• RoHS compliance: ROHS3 Compliant

Secondary Compatibility Parameters:

• Tolerance: ±0.02% preferred; ±0.1% acceptable with design verification
• Temperature coefficient: ±10ppm/°C preferred; ±5ppm/°C or ±25ppm/°C acceptable depending on circuit requirements
• Packaging format: Tape & Reel (TR) or alternative formats acceptable

Substitutes are classified into two categories: direct upgrades (identical electrical specifications with improved product status) and similar alternatives (compatible electrical parameters with minor specification variations).

Engineering Selection Recommendations

RG2012V-1580-P-T1 (Susumu) - Recommended Direct Upgrade

The RG2012V-1580-P-T1 is the primary substitute for the obsolete RG2012N-1580-P-T1. This component maintains identical electrical specifications (158 Ohms ±0.02%, 0.125W, 0805 package) while offering superior product status (Active vs. Obsolete). The RG2012V variant features an improved temperature coefficient of ±5ppm/°C compared to the original ±10ppm/°C specification, providing enhanced stability across the -55°C to 155°C operating range. Both components share identical physical dimensions, AEC-Q200 automotive qualification, ROHS3 compliance, and MSL 1 rating. The RG2012V-1580-P-T1 is available in Tape & Reel packaging format with 1140 units in current inventory.

ERA-6AEB1580V (Panasonic Electronic Components) - Compatible Alternative

The ERA-6AEB1580V serves as a compatible alternative when the Susumu RG2012V variant is unavailable. This Panasonic component maintains the same 158 Ohms resistance, 0.125W power rating, 0805 package, and AEC-Q200 automotive qualification. The primary specification difference is tolerance: ERA-6AEB1580V is rated at ±0.1% compared to the ±0.02% specification of the main part. The temperature coefficient is ±25ppm/°C, which is less stringent than both the original and upgraded Susumu variants. Physical dimensions are equivalent (0.079" L x 0.049" W), with a maximum seated height of 0.024" (0.60mm) versus 0.020" (0.50mm) for the Susumu parts. The ERA-6AEB1580V maintains ROHS3 compliance, MSL 1 rating, and is available in Tape & Reel format with 5500 units in inventory. This component is suitable for applications where the ±0.1% tolerance specification is acceptable.

Frequently Asked Questions (FAQ)

Q: Can the RG2012V-1580-P-T1 be used as a direct replacement for the RG2012N-1580-P-T1?

A: Yes. The RG2012V-1580-P-T1 is a direct substitute with identical electrical specifications (158 Ohms ±0.02%, 0.125W, 0805 package) and physical dimensions. The primary advantage is active product status versus obsolete status. The improved temperature coefficient (±5ppm/°C vs. ±10ppm/°C) provides enhanced performance.

Q: What is the tolerance difference between the main part and the ERA-6AEB1580V?

A: The RG2012N-1580-P-T1 specifies ±0.02% tolerance, while the ERA-6AEB1580V specifies ±0.1% tolerance. This represents a five-fold relaxation in tolerance specification. Applications requiring the tighter ±0.02% tolerance must use the Susumu RG2012V-1580-P-T1 variant.

Q: Are all three components physically compatible with the same PCB footprint?

A: Yes. All three components use the 0805 (2012 Metric) package with identical length (0.079") and width (0.049"). The ERA-6AEB1580V has a maximum seated height of 0.024" (0.60mm) compared to 0.020" (0.50mm) for the Susumu variants. This minor height difference does not affect standard PCB footprint compatibility.

Q: Do all substitute parts maintain automotive AEC-Q200 qualification?

A: Yes. The RG2012V-1580-P-T1 and ERA-6AEB1580V both carry AEC-Q200 automotive qualification, matching the original RG2012N-1580-P-T1 specification.

Q: What is the difference in temperature coefficient between the parts?

A: The RG2012N-1580-P-T1 specifies ±10ppm/°C, the RG2012V-1580-P-T1 specifies ±5ppm/°C (improved), and the ERA-6AEB1580V specifies ±25ppm/°C (relaxed). Temperature coefficient affects resistance stability across the -55°C to 155°C operating range. Applications with stringent temperature stability requirements should prioritize the RG2012V-1580-P-T1.

Q: Are these components RoHS compliant?

A: Yes. All three components are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: What packaging formats are available for the substitute parts?

A: Both the RG2012V-1580-P-T1 and ERA-6AEB1580V are supplied in Tape & Reel (TR) packaging format.
