Substitute Part Grouping Explanation

Substitution eligibility for the RG2012P-3571-D-T5 is determined by the following critical parameters:

Primary Matching Criteria:

• Resistance value: 3.57 kOhms (exact match required)
• Package configuration: 0805 (2012 Metric) (exact match required)
• Composition: Thin Film (exact match required)
• Temperature coefficient: ±25ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)

Secondary Compatibility Criteria:

• Tolerance: ±0.5% or tighter (±0.1% acceptable as upgrade)
• Power rating: 0.125W minimum (0.25W acceptable as upgrade)
• Automotive qualification: AEC-Q200 preferred for equivalent substitution
• RoHS and REACH compliance: ROHS3 Compliant and REACH Unaffected (maintained across all substitutes)

Identified substitutes fall into two categories: tolerance upgrades (±0.1% vs. ±0.5%) and power rating upgrades (0.25W vs. 0.125W). All substitutes maintain identical resistance, package, composition, and temperature characteristics.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Tolerance Upgrade): RG2012P-3571-B-T5 (Susumu) and ERA-6AEB3571V (Panasonic) are direct functional equivalents with improved tolerance specification (±0.1% vs. ±0.5%). Both maintain identical power rating (0.125W), package configuration (0805), and operating temperature range (-55°C ~ 155°C). Both retain AEC-Q200 automotive qualification. RG2012P-3571-B-T5 additionally maintains anti-sulfur coating. These substitutes are suitable for applications requiring tighter tolerance control without modification to circuit design or PCB layout.

Upgraded Alternative (Power Rating Increase): 6-2176092-5 (TE Connectivity Passive Product) provides increased power dissipation capability (0.25W vs. 0.125W) with improved tolerance (±0.1%). This part maintains identical resistance, package, and temperature characteristics. The increased seated height (0.026" vs. 0.020") must be evaluated for PCB clearance compatibility. This part does not carry AEC-Q200 automotive qualification and lacks specified anti-sulfur coating, limiting its use to non-automotive or non-harsh-environment applications.

Preferred Substitutes for Automotive Applications: RG2012P-3571-B-T5 and ERA-6AEB3571V are preferred for automotive or harsh-environment applications due to retained AEC-Q200 qualification. ERA-6AEB3571V offers the highest inventory availability (7531 pieces).

Frequently Asked Questions (FAQ)

Q: Can RG2012P-3571-B-T5 be used as a direct replacement for RG2012P-3571-D-T5?

A: Yes. RG2012P-3571-B-T5 is a direct functional equivalent with identical resistance (3.57 kOhms), power rating (0.125W), package (0805), and operating temperature range (-55°C ~ 155°C). The tolerance is improved from ±0.5% to ±0.1%, which is compatible with all applications designed for the original part. No circuit redesign or PCB modification is required.

Q: What is the difference between the Susumu and Panasonic substitutes?

A: Both RG2012P-3571-B-T5 (Susumu) and ERA-6AEB3571V (Panasonic) provide identical electrical performance with ±0.1% tolerance and 0.125W power rating. The primary difference is seated height: Susumu at 0.020" (0.50mm) and Panasonic at 0.024" (0.60mm). Both maintain AEC-Q200 automotive qualification. Selection depends on PCB clearance requirements and inventory availability.

Q: Can 6-2176092-5 be used in place of RG2012P-3571-D-T5?

A: 6-2176092-5 is electrically compatible for resistance, tolerance, and temperature characteristics. However, it differs in two critical aspects: increased power rating (0.25W vs. 0.125W) and increased seated height (0.026" vs. 0.020"). Additionally, this part lacks AEC-Q200 automotive qualification and anti-sulfur coating. Use is restricted to non-automotive applications where increased height does not create PCB clearance conflicts.

Q: Are all substitutes RoHS and REACH compliant?

A: Yes. All identified substitutes (RG2012P-3571-B-T5, 6-2176092-5, and ERA-6AEB3571V) are ROHS3 Compliant and REACH Unaffected, matching the compliance status of the original RG2012P-3571-D-T5.

Q: What is the significance of the ±25ppm/°C temperature coefficient?

A: The temperature coefficient of ±25ppm/°C specifies the maximum resistance change per degree Celsius across the operating temperature range (-55°C ~ 155°C). All identified substitutes maintain this identical specification, ensuring equivalent thermal stability and predictable performance across temperature extremes.

Q: Does the anti-sulfur coating affect substitution decisions?

A: The anti-sulfur coating on RG2012P-3571-D-T5 and RG2012P-3571-B-T5 provides enhanced reliability in harsh or corrosive environments. ERA-6AEB3571V and 6-2176092-5 do not specify anti-sulfur coating. For applications in sulfur-rich or corrosive environments, Susumu parts with anti-sulfur coating are preferred.

Q: What does Moisture Sensitivity Level 1 (Unlimited) mean?

A: MSL 1 (Unlimited) indicates the component has no moisture sensitivity restrictions. These parts do not require special moisture-controlled storage or handling procedures and can be stored under standard conditions indefinitely without degradation.
