Key Parameters

Substitute Part Grouping Explanation

Substitution of the RG2012N-434-C-T5 is determined by strict equivalence in the following parameters:

Critical Parameters (Must Match):

• Resistance value: 430 kOhms
• Power rating: 0.125W (1/8W)
• Package type: 0805 (2012 Metric)
• Composition: Thin Film
• Temperature coefficient: ±10ppm/°C
• Operating temperature range: -55°C to 155°C
• Automotive rating: AEC-Q200
• Anti-sulfur construction

Allowable Variation:

• Tolerance: The main part specifies ±0.25%. Substitute parts with equal or tighter tolerance (±0.1% or ±0.05%) are electrically compatible and represent performance upgrades.

All three substitute parts maintain identical resistance, power rating, package, thermal characteristics, and automotive compliance. The substitutes differ only in tolerance specification, which represents improved precision without affecting mechanical or thermal compatibility.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: RG2012N-434-B-T5

The RG2012N-434-B-T5 provides direct functional equivalence with improved tolerance specification (±0.1% versus ±0.25%). This part is active in production, ensuring long-term availability and supply chain continuity. It maintains all automotive compliance certifications and environmental ratings of the obsolete main part.

Secondary Recommendations: RG2012N-434-W-T1 and RG2012N-434-W-T5

Both RG2012N-434-W-T1 and RG2012N-434-W-T5 offer the highest precision tolerance (±0.05%) and are suitable for applications requiring tighter resistance control. These parts are active in production and fully compliant with AEC-Q200 automotive standards. The selection between these two variants depends on packaging requirements (Tape & Reel format is specified for both).

Obsolescence Mitigation

The RG2012N-434-C-T5 is classified as obsolete. All three substitute parts are active products from the same manufacturer (Susumu) within the RG series, ensuring design continuity and manufacturing consistency. Transition to any of these active alternatives eliminates obsolescence risk while maintaining electrical and mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can RG2012N-434-B-T5 be used as a direct replacement for RG2012N-434-C-T5?

A: Yes. The RG2012N-434-B-T5 is electrically and mechanically compatible. It provides identical resistance value, power rating, package dimensions, and thermal characteristics. The improved tolerance (±0.1% versus ±0.25%) represents enhanced precision without affecting circuit compatibility.

Q: What is the difference between the three substitute parts?

A: All three substitutes maintain identical resistance, power rating, package, and thermal specifications. The differences are tolerance specifications: RG2012N-434-B-T5 offers ±0.1% tolerance, while RG2012N-434-W-T1 and RG2012N-434-W-T5 both offer ±0.05% tolerance. Selection depends on precision requirements for the specific application.

Q: Are all substitute parts AEC-Q200 qualified?

A: Yes. All three substitute parts carry AEC-Q200 automotive qualification, anti-sulfur construction, and identical operating temperature range (-55°C to 155°C). They are suitable for automotive applications requiring the same reliability standards as the main part.

Q: Does the 0805 package dimension remain the same across all parts?

A: Yes. All parts, including the main part and all substitutes, use the 0805 (2012 Metric) package with identical physical dimensions: 0.079" L × 0.049" W (2.00mm × 1.25mm) and maximum seated height of 0.020" (0.50mm). PCB layout and footprint compatibility is maintained.

Q: Why is the main part RG2012N-434-C-T5 classified as obsolete?

A: The RG2012N-434-C-T5 is no longer in active production. The substitute parts represent the current active alternatives from Susumu that provide equivalent or superior performance specifications for the same 430 kOhms 0805 thin film resistor application.

Q: Are there any environmental or compliance differences between the main part and substitutes?

A: No. All parts are ROHS3 compliant, REACH unaffected, and carry identical environmental ratings. Moisture sensitivity level (MSL) is 1 (Unlimited) for all parts, indicating no special storage or handling requirements.
