RG2012P-3743-D-T5 Equivalent & Substitute Parts

Part Overview

The RG2012P-3743-D-T5 is a 374 kOhms ±0.5% thin film chip resistor manufactured by Susumu in 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 actively produced and available in high volume inventory. Substitute parts are identified when equivalent electrical and mechanical parameters are required for component procurement, inventory management, or supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RG2012P-3743-D-T5 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 374 kOhms
• Package / Case: 0805 (2012 Metric)
• Composition: Thin Film
• Temperature Coefficient: ±25ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation Parameters:

• Tolerance: ±0.5% (main part) to ±0.1% (substitute parts) — tighter tolerance is acceptable
• Power Rating: 0.125W (main part) to 0.25W (substitute part 4-2176094-8) — higher power rating is acceptable
• Automotive Rating: AEC-Q200 (main part) to unspecified (substitute parts) — presence of certification in main part does not restrict substitution

All three substitute parts maintain identical resistance, package, composition, temperature coefficient, and operating temperature range. Tolerance improvements and power rating increases represent enhanced or equivalent performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain active product status and ROHS3 compliance. Selection between the RG2012P-3743-D-T5 and its equivalents is based on the following criteria:

RG2012P-3743-D-T5 (Susumu): Select when anti-sulfur coating and automotive AEC-Q200 qualification are circuit requirements. This part provides the specified tolerance of ±0.5% and minimum seated height of 0.020" (0.50mm).

4-2176094-8 (TE Connectivity): Select when higher power dissipation capacity (0.25W) is required or when tighter tolerance (±0.1%) is beneficial. This part accommodates increased thermal load with maximum seated height of 0.026" (0.65mm).

ERA-6AEB3743V (Panasonic): Select when automotive AEC-Q200 qualification and tighter tolerance (±0.1%) are both required. This part combines automotive-grade performance with improved tolerance specification and maximum seated height of 0.024" (0.60mm).

RT0805BRD07374KL (YAGEO): Select when tighter tolerance (±0.1%) is required without automotive qualification constraints. This part provides improved tolerance specification with maximum seated height of 0.024" (0.60mm).

Frequently Asked Questions (FAQ)

Q: Can the RG2012P-3743-D-T5 be replaced with 4-2176094-8?

A: Yes. Both parts share identical resistance (374 kOhms), package (0805), composition (thin film), temperature coefficient (±25ppm/°C), and operating temperature range (-55°C ~ 155°C). The substitute part features tighter tolerance (±0.1% vs ±0.5%) and higher power rating (0.25W vs 0.125W). The maximum seated height increases from 0.020" to 0.026", which must be verified against PCB clearance requirements.

Q: What is the difference between ERA-6AEB3743V and RT0805BRD07374KL?

A: Both parts are functionally equivalent with 374 kOhms resistance, ±0.1% tolerance, 0.125W power rating, and 0805 package. ERA-6AEB3743V includes automotive AEC-Q200 qualification; RT0805BRD07374KL does not. Both have identical maximum seated height of 0.024" (0.60mm).

Q: Does tolerance improvement affect circuit performance?

A: Tolerance specifications define the acceptable resistance variation from the nominal value. Tighter tolerance (±0.1%) provides narrower resistance variation compared to ±0.5%. This affects circuit accuracy and stability. Selection depends on circuit design requirements for resistance precision.

Q: Are all substitute parts suitable for automotive applications?

A: The RG2012P-3743-D-T5 and ERA-6AEB3743V carry automotive AEC-Q200 qualification. The 4-2176094-8 and RT0805BRD07374KL do not specify automotive qualification. Automotive application requirements must be verified against circuit specifications.

Q: What is the impact of seated height variation?

A: Seated height ranges from 0.020" (0.50mm) for RG2012P-3743-D-T5 to 0.026" (0.65mm) for 4-2176094-8. PCB design clearance, component stacking, and assembly process specifications must accommodate the maximum seated height of the selected part.

Q: Can these parts be used interchangeably in existing designs?

A: Electrical interchangeability is confirmed for all substitute parts based on matching resistance, tolerance (equal or tighter), package, composition, and temperature characteristics. Mechanical interchangeability requires verification of PCB footprint, clearance, and assembly process compatibility, particularly regarding seated height variation.
