Substitute Part Grouping Explanation

Substitution of the RG2012N-301-D-T5 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 300 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
• RoHS3 compliance
• MSL 1 rating

Allowable Variation:

• Tolerance: The RG2012N-301-D-T5 specifies ±0.5% tolerance. Substitute parts with equal or tighter (lower) tolerance values are acceptable, as tighter tolerance represents improved performance within the same electrical specification.

The RG2012N-301-W-T1 meets all mandatory matching parameters and features a tighter tolerance specification of ±0.05%, making it a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the RG2012N-301-D-T5 and RG2012N-301-W-T1 are active production components manufactured by Susumu with identical electrical and mechanical specifications except for tolerance rating. Selection between these parts is based on application requirements and tolerance specifications:

RG2012N-301-D-T5 (±0.5% Tolerance): Suitable for general-purpose automotive and industrial applications where standard tolerance performance is acceptable. This part is appropriate for circuits where resistance value variation within ±0.5% does not impact circuit performance.

RG2012N-301-W-T1 (±0.05% Tolerance): Suitable for precision applications requiring tighter tolerance control. The ±0.05% tolerance specification provides improved accuracy and stability compared to the main part. This substitute is appropriate for circuits where resistance value precision is critical to circuit function or performance specifications.

Both parts carry AEC-Q200 automotive qualification, RoHS3 compliance, and MSL 1 rating, confirming suitability for automotive and high-reliability applications. Footprint compatibility is identical, allowing direct substitution without PCB redesign.

Frequently Asked Questions (FAQ)

Q: Can the RG2012N-301-W-T1 be used as a direct replacement for the RG2012N-301-D-T5?

A: Yes. The RG2012N-301-W-T1 is a direct substitute. Both parts share identical resistance value, power rating, package, composition, temperature coefficient, operating temperature range, and automotive qualification. The substitute features tighter tolerance (±0.05% versus ±0.5%), which represents improved performance within the same electrical specification.

Q: What is the difference between these two parts?

A: The primary difference is tolerance specification. The RG2012N-301-D-T5 specifies ±0.5% tolerance, while the RG2012N-301-W-T1 specifies ±0.05% tolerance. All other electrical and mechanical parameters are identical.

Q: Are both parts suitable for automotive applications?

A: Yes. Both the RG2012N-301-D-T5 and RG2012N-301-W-T1 carry AEC-Q200 automotive qualification and feature anti-sulfur coating, confirming suitability for automotive environments.

Q: Do these parts require different PCB footprints?

A: No. Both parts use the 0805 (2012 Metric) package with identical dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm) and maximum seated height of 0.020" (0.50mm). No PCB redesign is required for substitution.

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

A: Both parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the RG2012N-301-D-T5 and RG2012N-301-W-T1 are RoHS3 compliant and REACH unaffected.

Q: Which part should I select for my application?

A: Selection depends on tolerance requirements. Use the RG2012N-301-D-T5 for applications where ±0.5% tolerance is acceptable. Use the RG2012N-301-W-T1 for precision applications requiring ±0.05% tolerance control.
