Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RG2012P-3091-P-T1 is determined by the following critical parameters:

Primary Matching Criteria:

• Resistance value: 3.09 kOhms
• Tolerance: ±0.02%
• Package format: 0805 (2012 Metric)
• Composition: Thin Film
• Compliance: ROHS3, AEC-Q200 (where applicable)

Secondary Compatibility Factors:

• Power rating: Equal or greater than 0.125W
• Operating temperature range: Minimum -55°C ~ 155°C
• Temperature coefficient: ±25ppm/°C or better
• Moisture sensitivity: MSL 1 or equivalent

Substitute parts must maintain identical resistance and tolerance specifications to ensure circuit performance. Package dimensions must be mechanically compatible with 0805 footprints. Power rating may be increased without circuit impact. Temperature coefficient improvements are acceptable. All substitutes must maintain automotive-grade compliance where the original application requires it.

Engineering Selection Recommendations

RG2012V-3091-P-T1 (Susumu - Upgrade Substitute)

The RG2012V-3091-P-T1 is the primary recommended substitute for the obsolete RG2012P-3091-P-T1. This part maintains identical electrical specifications (3.09 kOhms, ±0.02%, 0.125W) and package format (0805). The upgrade variant offers improved temperature coefficient performance (±5ppm/°C versus ±25ppm/°C), enhanced stability, and active product status ensuring long-term availability. Both parts carry AEC-Q200 automotive qualification and ROHS3 compliance. The RG2012V-3091-P-T1 is the direct functional replacement with superior performance characteristics.

PLTT0805Z3091QGT5 (Vishay Dale Thin Film - Similar Substitute)

The PLTT0805Z3091QGT5 provides an alternative substitute option with identical resistance and tolerance specifications. This part features a higher power rating (0.25W versus 0.125W), extended operating temperature range (-55°C ~ 215°C), and improved temperature coefficient (±5ppm/°C). The increased power rating and thermal capability provide design margin for applications requiring enhanced thermal performance. However, this part does not carry explicit AEC-Q200 designation. Selection of this substitute is appropriate for non-automotive applications or where the enhanced thermal specifications provide circuit benefit.

Frequently Asked Questions (FAQ)

Q: Can the RG2012V-3091-P-T1 be used as a direct replacement for the RG2012P-3091-P-T1?

A: Yes. The RG2012V-3091-P-T1 is a direct functional replacement. Both parts share identical resistance (3.09 kOhms), tolerance (±0.02%), power rating (0.125W), and package format (0805). The upgrade variant offers superior temperature coefficient performance and active product status.

Q: What is the difference between the RG2012P-3091-P-T1 and RG2012V-3091-P-T1?

A: The primary differences are product status and temperature coefficient. The RG2012P-3091-P-T1 is obsolete with ±25ppm/°C temperature coefficient, while the RG2012V-3091-P-T1 is active with ±5ppm/°C temperature coefficient. Electrical specifications and package format are identical.

Q: Is the PLTT0805Z3091QGT5 suitable for automotive applications?

A: The PLTT0805Z3091QGT5 does not carry explicit AEC-Q200 automotive qualification. For automotive applications requiring AEC-Q200 compliance, the RG2012V-3091-P-T1 is the appropriate selection.

Q: Can I use the PLTT0805Z3091QGT5 in place of the RG2012P-3091-P-T1?

A: The PLTT0805Z3091QGT5 is electrically compatible with identical resistance and tolerance specifications. The higher power rating (0.25W) and extended temperature range (-55°C ~ 215°C) provide additional design margin. However, the absence of AEC-Q200 designation must be evaluated against application requirements.

Q: Are all three parts mechanically compatible with 0805 footprints?

A: Yes. All three parts are packaged in 0805 (2012 Metric) format and are mechanically compatible with standard 0805 PCB footprints. Minor dimensional variations exist within specification tolerances but do not affect assembly or functionality.

Q: What is the temperature coefficient significance for this resistor?

A: Temperature coefficient indicates resistance value drift with temperature change. The RG2012P-3091-P-T1 exhibits ±25ppm/°C drift, while both substitute options offer ±5ppm/°C. Lower temperature coefficient values indicate superior stability across the operating temperature range, reducing circuit performance variation in thermal environments.

Q: Why is the RG2012P-3091-P-T1 classified as obsolete?

A: Product obsolescence indicates the manufacturer has discontinued production. The RG2012V-3091-P-T1 represents the active replacement in the Susumu RG series, providing equivalent functionality with improved specifications and guaranteed long-term availability.
