RG2012P-2550-B-T5 Equivalent & Substitute Parts

Part Overview

The RG2012P-2550-B-T5 is a 255 Ohm thin film chip resistor manufactured by Susumu in 0805 (2012 Metric) package format. This component is rated for 0.125W (1/8W) power dissipation with ±0.1% tolerance and features anti-sulfur coating with automotive AEC-Q200 qualification. The part is actively produced and available in high volume. Substitute parts are identified for applications requiring equivalent electrical performance, alternative sourcing, or inventory availability across multiple manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RG2012P-2550-B-T5 is determined by the following critical parameters:

Primary Substitution Criteria (Must Match):

• Resistance value: 255 Ohms
• Tolerance: ±0.1%
• Package: 0805 (2012 Metric)
• Composition: Thin Film
• Temperature Coefficient: ±25ppm/°C
• Operating Temperature Range: -55°C to 155°C
• RoHS3 Compliance
• MSL 1 Rating

Secondary Substitution Criteria (Allowable Variation):

• Power Rating: Substitute parts rated at 0.125W (1/8W) or higher are acceptable. The 6-2176091-2 substitute rated at 0.25W (1/4W) exceeds the minimum power requirement and is therefore suitable.
• Automotive Qualification: AEC-Q200 rating is present on the main part and ERA-6AEB2550V substitute. Absence of this rating on other substitutes does not preclude substitution for non-automotive applications.
• Physical Height: Seated height variations within 0.026" (0.65mm) maximum are acceptable for 0805 package footprint compatibility.

All four parts meet the primary substitution criteria. The 6-2176091-2 substitute provides increased power handling capability while maintaining all other electrical specifications.

Parameter Comparison

Engineering Selection Recommendations

For Automotive Applications (AEC-Q200 Required): The RG2012P-2550-B-T5 and ERA-6AEB2550V are qualified substitutes. Both components carry AEC-Q200 certification and meet all electrical and environmental specifications. ERA-6AEB2550V offers higher inventory availability (14,594 units) compared to the main part (659 units).

For General Industrial Applications: All four parts are suitable substitutes. The 6-2176091-2 (TE Connectivity) provides increased power margin at 0.25W rating while maintaining identical electrical characteristics. The RT0805BRD07255RL (YAGEO) and ERA-6AEB2550V offer alternative sourcing with comparable specifications.

For Space-Constrained Designs: The RG2012P-2550-B-T5 provides the minimum seated height at 0.020" (0.50mm). The ERA-6AEB2550V and RT0805BRD07255RL at 0.024" (0.60mm) are functionally equivalent for standard 0805 footprints. The 6-2176091-2 at 0.026" (0.65mm) remains within acceptable tolerance for 0805 package specifications.

For High-Volume Production: ERA-6AEB2550V (Panasonic) demonstrates the highest inventory level at 14,594 units, supporting sustained production requirements.

Frequently Asked Questions (FAQ)

Q: Can the 6-2176091-2 substitute for the RG2012P-2550-B-T5 in all applications?

A: Yes. The 6-2176091-2 is electrically equivalent with identical resistance, tolerance, temperature coefficient, and operating range. The increased power rating (0.25W vs. 0.125W) provides additional thermal margin and does not create compatibility issues. Physical height difference (0.026" vs. 0.020") remains within 0805 package specifications.

Q: Are the ERA-6AEB2550V and RG2012P-2550-B-T5 interchangeable for automotive applications?

A: Yes. Both components carry AEC-Q200 certification and share identical electrical specifications: 255 Ohms ±0.1%, 0.125W power rating, ±25ppm/°C temperature coefficient, and -55°C to 155°C operating range. Physical dimensions are compatible with standard 0805 footprints.

Q: What is the significance of the ±0.1% tolerance specification?

A: The ±0.1% tolerance indicates precision thin film construction. All substitute parts maintain this tolerance, ensuring consistent performance in precision analog circuits, reference networks, and measurement applications where tight tolerance is required.

Q: Does the absence of AEC-Q200 rating on the 6-2176091-2 and RT0805BRD07255RL affect substitution?

A: AEC-Q200 certification is required only for automotive applications subject to automotive qualification standards. For industrial, consumer, and general-purpose applications, the absence of this rating does not affect substitution eligibility. Component selection should align with application requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All four parts carry ROHS3 Compliance certification, meeting environmental and regulatory requirements for lead-free manufacturing and restricted substance limitations.

Q: What does MSL 1 (Unlimited) moisture sensitivity rating indicate?

A: MSL 1 rating indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. All substitute parts share this rating, eliminating moisture-related storage or reflow process constraints.

Q: Can these parts be used interchangeably in existing PCB designs without layout modifications?

A: Yes. All parts use the 0805 (2012 Metric) package with identical footprint dimensions (0.079" L x 0.049" W). Physical height variations are within acceptable tolerance for standard PCB assembly processes. No layout modifications are required.
