Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RG2012N-271-B-T5 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 270 Ohms
• Package / Case: 0805 (2012 Metric)
• Power rating: 0.125W (1/8W)
• Composition: Thin Film
• Temperature coefficient: ±10ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Features: Anti-Sulfur, Automotive AEC-Q200
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

Variable Parameter Allowing Substitution:

• Tolerance: The RG2012N-271-B-T5 operates at ±0.1% tolerance. Substitute parts with equal or tighter (lower) tolerance values are electrically and functionally compatible, as they meet or exceed the precision requirements of the original specification.

The identified substitute maintains all mandatory parameters while offering improved tolerance performance, making it suitable for applications requiring higher precision without modification to circuit design or PCB layout.

Parameter Comparison

Engineering Selection Recommendations

Both the RG2012N-271-B-T5 and RG2012N-271-W-T1 are active production parts manufactured by Susumi with full AEC-Q200 automotive qualification and ROHS3 compliance. The parts are electrically and mechanically interchangeable on PCB assemblies without design modification or layout changes.

The RG2012N-271-W-T1 substitute offers tighter tolerance specification (±0.05% versus ±0.1%), providing enhanced precision for applications requiring stricter resistance value control. Both parts maintain identical thermal characteristics, package dimensions, and environmental ratings across the full operating temperature range of -55°C to 155°C.

Selection between these parts depends on application tolerance requirements. The main part RG2012N-271-B-T5 is suitable for general-purpose automotive and industrial applications. The substitute RG2012N-271-W-T1 is appropriate for precision measurement circuits, calibration networks, or applications with tighter tolerance budgets.

Frequently Asked Questions (FAQ)

Q: Can RG2012N-271-W-T1 be used as a direct replacement for RG2012N-271-B-T5?

A: Yes. The RG2012N-271-W-T1 is a direct substitute. Both parts share identical resistance value, package, power rating, temperature coefficient, and operating temperature range. The substitute features improved tolerance (±0.05% versus ±0.1%), which is a performance enhancement rather than a limitation. No PCB layout or circuit design changes are required.

Q: What is the difference between these two part numbers?

A: The primary difference is tolerance specification. RG2012N-271-B-T5 operates at ±0.1% tolerance, while RG2012N-271-W-T1 operates at ±0.05% tolerance. All other electrical and mechanical parameters are identical. The tighter tolerance of the substitute part provides higher precision resistance values.

Q: Are both parts AEC-Q200 qualified?

A: Yes. Both RG2012N-271-B-T5 and RG2012N-271-W-T1 carry AEC-Q200 automotive qualification and anti-sulfur coating, making them suitable for automotive and harsh environment applications.

Q: Do these parts have the same package dimensions?

A: Yes. Both parts are packaged in 0805 (2012 Metric) format with identical dimensions of 0.079" L x 0.049" W (2.00mm x 1.25mm) and maximum seated height of 0.020" (0.50mm). They are footprint-compatible on PCB assemblies.

Q: What is the moisture sensitivity level for these parts?

A: Both parts have Moisture Sensitivity Level (MSL) rating of 1, which indicates unlimited shelf life and no special moisture control requirements during storage or handling.

Q: Are both parts RoHS compliant?

A: Yes. Both RG2012N-271-B-T5 and RG2012N-271-W-T1 are ROHS3 compliant and REACH unaffected, meeting environmental and regulatory requirements for commercial and automotive applications.
