RG2012P-124-D-T5 Equivalent & Substitute Parts

Part Overview

The RG2012P-124-D-T5 is a 120 kOhms ±0.5% thin film chip resistor manufactured by Susumu in 0805 (2012 Metric) package format. This surface-mount device is rated for 0.125W (1/8W) power dissipation and is qualified to AEC-Q200 automotive standards with anti-sulfur coating. The part is active in production status with RoHS3 compliance and unlimited moisture sensitivity level (MSL 1). Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and design continuity when the primary part becomes unavailable or when design requirements necessitate alternative tolerance specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RG2012P-124-D-T5 are classified based on the following substitution criteria:

Direct Equivalents (Same Tolerance ±0.5%): Parts that maintain identical electrical specifications including resistance value, tolerance, power rating, temperature coefficient, and operating temperature range. These parts are interchangeable without circuit performance impact.

Upgrade Substitutes (Tighter Tolerance ±0.1%): Parts that exceed the original specification by providing ±0.1% tolerance instead of ±0.5%. These parts are electrically compatible and suitable for applications requiring improved precision. Tighter tolerance does not degrade circuit function in designs specified for ±0.5%.

Common Substitution Parameters:

• Resistance: 120 kOhms (exact match required)
• Power Rating: 0.125W (1/8W) (exact match required)
• Package: 0805 (2012 Metric) (exact match required)
• Composition: Thin Film (exact match required)
• Temperature Coefficient: ±25ppm/°C (exact match required)
• Operating Temperature: -55°C ~ 155°C (exact match required)
• RoHS3 Compliance: Required
• MSL Rating: 1 (Unlimited) (exact match required)

Parameter Comparison

Engineering Selection Recommendations

For Direct Substitution (Same Tolerance ±0.5%):

The RT0805DRD07120KL (YAGEO) is a direct electrical equivalent with matching ±0.5% tolerance and identical electrical parameters. This part is suitable for applications where AEC-Q200 qualification is not a design requirement. The maximum seated height of 0.60mm versus 0.50mm for the primary part must be verified against PCB assembly clearance constraints.

For Upgraded Tolerance (±0.1%):

Three upgrade options are available with tighter ±0.1% tolerance:

• RG2012P-124-B-T5 (Susumu): Same manufacturer as the primary part, maintains AEC-Q200 qualification and identical 0.50mm maximum height. This option provides the highest design continuity with improved tolerance specification.

• ERA-6AEB124V (Panasonic Electronic Components): Maintains AEC-Q200 qualification with ±0.1% tolerance. Maximum seated height is 0.60mm. This part is supplied in Cut Tape (CT) & Digi-Reel® packaging format rather than standard Tape & Reel.

• RT0805BRD07120KL (YAGEO): Provides ±0.1% tolerance with maximum seated height of 0.60mm. AEC-Q200 qualification is not included in this part specification.

Compliance Considerations:

All substitute parts maintain RoHS3 compliance, MSL 1 rating, and identical operating temperature range (-55°C ~ 155°C). For automotive applications requiring AEC-Q200 qualification, selection is limited to RG2012P-124-B-T5, ERA-6AEB124V, or the primary part RG2012P-124-D-T5.

Frequently Asked Questions (FAQ)

Q: Can RT0805DRD07120KL be used as a direct replacement for RG2012P-124-D-T5 in automotive applications?

A: RT0805DRD07120KL matches all electrical parameters and tolerance specifications. However, it does not carry AEC-Q200 qualification. Use this part only in non-automotive applications or where AEC-Q200 is not a design requirement. The 0.10mm difference in maximum seated height (0.60mm vs. 0.50mm) must be verified against PCB assembly specifications.

Q: What is the difference between the upgrade parts with ±0.1% tolerance?

A: All three upgrade parts (RG2012P-124-B-T5, ERA-6AEB124V, RT0805BRD07120KL) provide ±0.1% tolerance instead of ±0.5%. The primary differences are: RG2012P-124-B-T5 maintains the same manufacturer and height; ERA-6AEB124V includes AEC-Q200 but uses different packaging; RT0805BRD07120KL lacks AEC-Q200 qualification. Selection depends on automotive requirements and packaging constraints.

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

A: No. RG2012P-124-D-T5, RG2012P-124-B-T5, RT0805DRD07120KL, and RT0805BRD07120KL are supplied in Tape & Reel (TR) format. ERA-6AEB124V is supplied in Cut Tape (CT) & Digi-Reel® format. Verify packaging compatibility with your procurement and assembly processes.

Q: Can I use a ±0.1% tolerance part in a circuit designed for ±0.5% tolerance?

A: Yes. A tighter tolerance specification is electrically compatible with designs specified for ±0.5%. The ±0.1% part will perform within the ±0.5% tolerance window and provides improved precision without circuit degradation.

Q: What is the maximum seated height difference between substitute parts?

A: The primary part RG2012P-124-D-T5 has a maximum seated height of 0.50mm. Substitute parts RT0805DRD07120KL, ERA-6AEB124V, and RT0805BRD07120KL have a maximum seated height of 0.60mm. This 0.10mm difference must be evaluated against PCB assembly clearance and component placement constraints.

Q: Which substitute part is recommended for new automotive designs?

A: RG2012P-124-B-T5 is recommended for new automotive designs. It maintains the same manufacturer (Susumu), includes AEC-Q200 qualification, provides improved ±0.1% tolerance, and matches the original 0.50mm maximum seated height. ERA-6AEB124V is an alternative if Panasonic sourcing is preferred, with the trade-off of different packaging format and increased height.
