RG2012P-2433-W-T1 Equivalent & Substitute Parts

Part Overview

The RG2012P-2433-W-T1 is a 243 kOhms ±0.05% thin film chip resistor manufactured by Susumu in the 0805 (2012 Metric) package format. This component is rated for 0.125W (1/8W) power dissipation and features anti-sulfur coating with automotive AEC-Q200 qualification. The part is currently listed as obsolete, necessitating identification of equivalent and substitute components for ongoing design support and procurement continuity. Equivalent parts maintain identical electrical and mechanical specifications, while substitute parts offer functional alternatives with minor parameter variations acceptable for most applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RG2012P-2433-W-T1 is determined by the following critical parameters: resistance value (243 kOhms), package format (0805 / 2012 Metric), power rating (0.125W), composition (thin film), operating temperature range (-55°C ~ 155°C), and automotive qualification (AEC-Q200). Tolerance and temperature coefficient variations are permitted within acceptable engineering margins for most applications. Parts are grouped into three categories: direct equivalents (identical specifications and packaging), upgrades (improved performance characteristics), and similar alternatives (minor parameter deviations with functional compatibility).

Engineering Selection Recommendations

RG2012P-2433-W-T5 (Direct Equivalent): This Susumu component is the primary direct substitute for the obsolete RG2012P-2433-W-T1. It maintains identical electrical specifications (243 kOhms ±0.05%, 0.125W, ±25ppm/°C) and mechanical form factor (0805 package). The part is currently in active production status with Tape & Reel packaging, ensuring procurement availability. All compliance certifications (AEC-Q200, ROHS3, REACH Unaffected) are maintained. This part is suitable for direct replacement in existing designs without circuit modification.

RG2012N-2433-W-T1 (Upgrade Alternative): This Susumu component offers improved performance through a reduced temperature coefficient of ±10ppm/°C compared to the original ±25ppm/°C specification. All other electrical parameters (243 kOhms ±0.05%, 0.125W) and mechanical specifications remain identical. The part is in active production with full automotive and compliance certifications. This option is applicable for applications requiring enhanced temperature stability without design changes.

ERA-6AEB2433V (Cross-Manufacturer Alternative): This Panasonic component provides functional compatibility with a tolerance specification of ±0.1% (versus the original ±0.05%). All other critical parameters align: 243 kOhms resistance, 0.125W power rating, 0805 package, thin film composition, -55°C ~ 155°C operating range, and AEC-Q200 automotive qualification. The part is in active production with extensive inventory availability. This option is suitable for applications where the ±0.1% tolerance is acceptable within circuit design margins.

Frequently Asked Questions (FAQ)

Q: Can RG2012P-2433-W-T5 be used as a direct replacement for RG2012P-2433-W-T1?

A: Yes. RG2012P-2433-W-T5 is a direct equivalent with identical electrical specifications (243 kOhms ±0.05%, 0.125W, ±25ppm/°C) and mechanical package (0805). The primary difference is packaging format (Tape & Reel versus unspecified) and active product status. No circuit modifications are required.

Q: What is the difference between RG2012N-2433-W-T1 and the original part?

A: RG2012N-2433-W-T1 differs only in temperature coefficient specification: ±10ppm/°C versus the original ±25ppm/°C. All other parameters—resistance, tolerance, power rating, package, and operating temperature range—are identical. This represents improved thermal stability for precision applications.

Q: Is ERA-6AEB2433V compatible with the original RG2012P-2433-W-T1?

A: ERA-6AEB2433V is functionally compatible with a tolerance specification of ±0.1% instead of ±0.05%. All other critical parameters match: 243 kOhms, 0.125W, 0805 package, thin film composition, AEC-Q200 rating, and -55°C ~ 155°C operating range. Compatibility depends on circuit tolerance requirements.

Q: Are all substitute parts AEC-Q200 qualified?

A: Yes. All listed substitute parts (RG2012P-2433-W-T5, RG2012N-2433-W-T1, and ERA-6AEB2433V) carry AEC-Q200 automotive qualification, matching the original part specification.

Q: What is the difference between the packaging formats?

A: The original RG2012P-2433-W-T1 packaging format is not specified in the data. All substitute parts are supplied in Tape & Reel (TR) format, which is standard for automated assembly processes. This format difference does not affect electrical or mechanical compatibility.

Q: Can these parts be used interchangeably in high-precision circuits?

A: RG2012P-2433-W-T5 and RG2012N-2433-W-T1 maintain the ±0.05% tolerance of the original part and are fully interchangeable. ERA-6AEB2433V has a ±0.1% tolerance and is suitable for applications where this tolerance is acceptable within design specifications.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts (RG2012P-2433-W-T5, RG2012N-2433-W-T1, and ERA-6AEB2433V) are ROHS3 compliant and REACH unaffected, matching the original part's environmental compliance status.
