Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RG2012P-302-P-T1 is determined by the following critical parameters:

Primary Matching Criteria:

• Resistance value: 3 kOhms (exact match required)
• Package format: 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 Factors:

• Tolerance specification (tighter tolerances are acceptable)
• Temperature coefficient (lower values indicate superior stability)
• Moisture sensitivity level (MSL 1 is acceptable)

Parts are grouped as direct upgrades when all primary criteria are met with improved or equivalent secondary specifications. Parts are grouped as similar alternatives when primary criteria are met but with relaxed tolerance specifications.

Engineering Selection Recommendations

RG2012V-302-P-T1 (Susumu) - Direct Upgrade:

The RG2012V-302-P-T1 is the primary substitute for the obsolete RG2012P-302-P-T1. Both components are manufactured by Susumu and share identical electrical specifications: 3 kOhms resistance, ±0.02% tolerance, 0.125W power rating, and 0805 package format. The upgrade variant features an improved temperature coefficient of ±5ppm/°C compared to ±25ppm/°C in the original part, providing superior temperature stability. The RG2012V-302-P-T1 maintains active product status and full AEC-Q200 automotive qualification, ROHS3 compliance, and MSL 1 rating. This component is the recommended first choice for direct replacement in existing designs.

ERA-6ARW302V (Panasonic Electronic Components) - Alternative Substitute:

The ERA-6ARW302V from Panasonic Electronic Components serves as a compatible alternative when the Susumu upgrade is unavailable. This component meets all primary substitution criteria with identical 3 kOhms resistance, 0.125W power rating, 0805 package format, and AEC-Q200 automotive qualification. The tolerance specification is relaxed to ±0.05% compared to the original ±0.02%, and the temperature coefficient is ±10ppm/°C. The ERA-6ARW302V maintains active product status, ROHS3 compliance, and MSL 1 rating. This part is suitable for applications where the tighter tolerance of the original specification is not critical to circuit performance.

Frequently Asked Questions (FAQ)

Q: Can the RG2012V-302-P-T1 be used as a direct replacement for the RG2012P-302-P-T1?

A: Yes. Both components share identical resistance (3 kOhms), tolerance (±0.02%), power rating (0.125W), package format (0805), and automotive qualification (AEC-Q200). The RG2012V-302-P-T1 features improved temperature stability with a ±5ppm/°C coefficient versus ±25ppm/°C in the original part.

Q: What is the difference between the Susumu upgrade and the Panasonic alternative?

A: The primary difference is tolerance specification. The Susumu RG2012V-302-P-T1 maintains ±0.02% tolerance matching the original part, while the Panasonic ERA-6ARW302V has ±0.05% tolerance. Both meet AEC-Q200 automotive requirements and share identical package and power specifications.

Q: Are all substitute parts available in the same packaging format?

A: The RG2012P-302-P-T1 original part is supplied in standard packaging. The RG2012V-302-P-T1 upgrade is available in Tape & Reel (TR) format. The ERA-6ARW302V alternative is also available in Tape & Reel (TR) format. Verify packaging requirements for your procurement process.

Q: Do all substitute parts meet automotive qualification standards?

A: Yes. Both the RG2012V-302-P-T1 and ERA-6ARW302V are rated to AEC-Q200 automotive standards and are ROHS3 compliant with MSL 1 moisture sensitivity level.

Q: Which substitute should be selected for precision analog circuits?

A: The RG2012V-302-P-T1 is the preferred choice for precision applications due to its ±0.02% tolerance matching the original specification and superior ±5ppm/°C temperature coefficient. The ERA-6ARW302V with ±0.05% tolerance is suitable for general-purpose applications where tighter tolerance is not required.

Q: What is the operating temperature range for substitute parts?

A: Both substitute components operate across the full -55°C to 155°C temperature range, matching the original RG2012P-302-P-T1 specification.
