RG2012P-912-D-T5 Equivalent & Substitute Parts

Part Overview

The RG2012P-912-D-T5 is a 9.1 kOhms ±0.5% thin film chip resistor in 0805 (2012 Metric) package rated for 0.125W (1/8W) power dissipation. Manufactured by Susumu, this component features anti-sulfur coating and automotive AEC-Q200 qualification, suitable for high-reliability applications operating across -55°C to 155°C. The part is active in production with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Equivalent and substitute parts are identified based on matching resistance value, package configuration, power rating, and automotive qualification requirements. Alternative sources and tighter tolerance options are available from Panasonic Electronic Components and YAGEO manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters:

Mandatory Matching Criteria:

• Resistance value: 9.1 kOhms
• Package / Case: 0805 (2012 Metric)
• Power rating: 0.125W (1/8W)
• Composition: Thin Film
• Operating temperature range: -55°C ~ 155°C
• Automotive AEC-Q200 qualification

Allowable Variations:

• Tolerance: Tighter tolerances (±0.1%, ±0.05%) are acceptable as upgrades
• Temperature coefficient: Variations within ±10ppm/°C to ±25ppm/°C are acceptable
• Manufacturer: Susumu, Panasonic Electronic Components, YAGEO
• Packaging format: Tape & Reel (TR) or Cut Tape (CT) & Digi-Reel®
• Physical height: Maximum seated height up to 0.024" (0.60mm) acceptable

All substitute parts maintain identical electrical performance at the specified resistance and power rating while offering equivalent or improved tolerance specifications and automotive compliance.

Parameter Comparison

Engineering Selection Recommendations

Primary Equivalent (Same Tolerance): RG2012P-912-B-T5 (Susumu) provides direct equivalence with improved tolerance (±0.1% vs ±0.5%) while maintaining identical temperature coefficient and physical dimensions. Both parts are Susumu products with anti-sulfur coating and AEC-Q200 automotive qualification in Tape & Reel packaging.

Upgraded Tolerance Options: ERA-6ARW912V (Panasonic) offers the tightest tolerance specification at ±0.05% with superior temperature coefficient (±10ppm/°C) and maintains full AEC-Q200 compliance. ERA-6ARB912V and ERA-6APB912V provide ±0.1% tolerance with progressively improved temperature coefficients (±10ppm/°C and ±15ppm/°C respectively).

Alternative Packaging: ERA-6AEB912V (Panasonic) is available in Cut Tape (CT) & Digi-Reel® format with ±0.1% tolerance and AEC-Q200 rating, suitable for applications requiring alternative tape configurations.

Cross-Manufacturer Option: RT0805BRD079K1L (YAGEO) provides ±0.1% tolerance and identical electrical specifications. AEC-Q200 rating is not specified for this part; verification against application requirements is necessary.

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and identical operating temperature range (-55°C ~ 155°C).

Frequently Asked Questions (FAQ)

Q: Can RG2012P-912-B-T5 directly replace RG2012P-912-D-T5? A: Yes. Both parts are manufactured by Susumu in 0805 package with 9.1 kOhms resistance and 0.125W power rating. RG2012P-912-B-T5 offers tighter tolerance (±0.1% vs ±0.5%) and is electrically compatible. Both feature anti-sulfur coating and AEC-Q200 automotive qualification.

Q: What is the difference between Panasonic ERA-6A series variants? A: All Panasonic ERA-6A variants (ERA-6AEB912V, ERA-6APB912V, ERA-6ARB912V, ERA-6ARW912V) share identical 9.1 kOhms resistance and 0.125W power rating. Differences exist in tolerance and temperature coefficient: ERA-6AEB912V and ERA-6APB912V offer ±0.1% tolerance; ERA-6ARB912V and ERA-6ARW912V provide ±0.1% and ±0.05% respectively with superior temperature coefficients (±10ppm/°C or better).

Q: Is RT0805BRD079K1L suitable for automotive applications? A: RT0805BRD079K1L meets the 0805 package, 9.1 kOhms resistance, and 0.125W power specifications. However, AEC-Q200 automotive qualification is not specified in the component data. Confirmation against specific automotive application requirements is necessary before selection.

Q: What packaging formats are available? A: RG2012P-912-D-T5, RG2012P-912-B-T5, and all Panasonic ERA-6A variants (except ERA-6AEB912V) are supplied in Tape & Reel (TR) format. ERA-6AEB912V is available in Cut Tape (CT) & Digi-Reel® format. RT0805BRD079K1L is supplied in Tape & Reel (TR).

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, matching the original RG2012P-912-D-T5 specification.

Q: What is the maximum seated height difference between parts? A: RG2012P-912-D-T5 has maximum seated height of 0.020" (0.50mm). Panasonic ERA-6A series and YAGEO RT0805BRD079K1L have maximum seated height of 0.024" (0.60mm). This 0.004" (0.10mm) difference is within standard PCB design tolerances for 0805 package applications.

Q: Which substitute offers the best temperature stability? A: ERA-6ARW912V and ERA-6ARB912V both feature ±10ppm/°C temperature coefficient, superior to the original RG2012P-912-D-T5 specification of ±25ppm/°C. ERA-6ARW912V additionally provides the tightest tolerance at ±0.05%.
