Key Parameters

Substitute Part Grouping Explanation

Substitution of the RG2012N-301-B-T5 is determined by the following critical parameters that must remain constant across equivalent parts:

Fixed Parameters (Non-Negotiable):

• Resistance value: 300 Ohms
• Package type: 0805 (2012 Metric)
• Power rating: 0.125W (1/8W)
• Composition: Thin Film
• Temperature coefficient: ±10ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Automotive qualification: AEC-Q200
• Anti-sulfur feature
• RoHS3 compliance

Variable Parameters (Allowed to Differ):

• Tolerance: The RG2012N-301-B-T5 specifies ±0.1% tolerance. Substitute parts with tighter (lower) tolerance values are acceptable as they meet or exceed the original specification.

The identified substitute RG2012N-301-W-T1 maintains all fixed parameters while offering improved tolerance performance at ±0.05%, making it a direct upgrade path for applications requiring higher precision.

Parameter Comparison

Engineering Selection Recommendations

RG2012N-301-B-T5 Selection Criteria:

• Standard tolerance requirement of ±0.1% is acceptable
• Cost optimization is a priority
• General-purpose automotive and industrial applications
• Adequate inventory availability (703 units in stock)

RG2012N-301-W-T1 Selection Criteria:

• Enhanced precision requirement of ±0.05% tolerance
• High-reliability or precision measurement applications
• Superior long-term stability performance
• Larger inventory availability (2,556 units in stock)

Both parts maintain identical electrical performance across all critical parameters including power dissipation, temperature stability, and operating range. Both are AEC-Q200 qualified, RoHS3 compliant, and feature anti-sulfur coating for automotive environments. The selection between these parts is determined by tolerance specification requirements and application precision demands.

Frequently Asked Questions (FAQ)

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

A: Yes. The RG2012N-301-W-T1 is a direct substitute with identical package, power rating, resistance value, and operating characteristics. The ±0.05% tolerance of the substitute is tighter than the ±0.1% specification of the original part, making it compatible with all applications designed for the RG2012N-301-B-T5.

Q: What is the primary difference between these two parts?

A: The primary difference is tolerance specification. The RG2012N-301-B-T5 offers ±0.1% tolerance, while the RG2012N-301-W-T1 provides ±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-B-T5 and RG2012N-301-W-T1 carry AEC-Q200 automotive qualification and feature anti-sulfur coating, making them suitable for automotive and harsh environment applications.

Q: Do these parts have the same physical footprint?

A: Yes. Both parts use the 0805 (2012 Metric) package 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 pin-compatible and require no PCB layout modifications.

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

A: Both parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions and unlimited shelf life under standard storage conditions.

Q: Are both parts RoHS3 compliant?

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