Key Parameters

Substitute Part Grouping Explanation

Substitution of the RG2012N-680-C-T5 is determined by strict equivalence in the following parameters:

Mandatory Equivalence Parameters:

• Resistance value: 68 Ohms (exact match required)
• Package type: 0805 (2012 Metric) (exact match required)
• Power rating: 0.125W (1/8W) (exact match required)
• Composition: Thin Film (exact match required)
• Temperature coefficient: ±10ppm/°C (exact match required)
• Operating temperature range: -55°C to 155°C (exact match required)
• Automotive qualification: AEC-Q200 (exact match required)
• Anti-sulfur feature: Present (exact match required)

Allowable Variation Parameters:

• Tolerance: May be tighter (lower value) than ±0.25% without affecting mechanical or thermal compatibility
• Product status: Active alternatives are preferred over obsolete status
• Packaging format: Tape & Reel (TR) is compatible with the original component application

All substitute parts listed maintain identical electrical performance characteristics and physical dimensions, differing only in tolerance specification and product availability status.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: RG2012N-680-W-T1

The RG2012N-680-W-T1 is the preferred substitute for the obsolete RG2012N-680-C-T5. This part maintains all mandatory electrical and mechanical parameters while offering superior tolerance specification (±0.05% versus ±0.25%). The component carries active product status, ensuring long-term availability and supply chain continuity. Highest inventory level (2000 Pcs) supports production requirements. Full AEC-Q200 automotive qualification and ROHS3 compliance are maintained.

Secondary Substitute: RG2012N-680-W-T5

The RG2012N-680-W-T5 provides equivalent performance to the primary substitute with identical tolerance (±0.05%) and all electrical characteristics. This part differs only in tape reel configuration (T5 versus T1). Active product status and substantial inventory (1067 Pcs) ensure availability. Selection between RG2012N-680-W-T1 and RG2012N-680-W-T5 depends on specific tape reel packaging requirements for automated assembly equipment.

Tertiary Substitute: RG2012N-680-B-T5

The RG2012N-680-B-T5 serves as an alternative when the tighter tolerance options are unavailable. This part offers ±0.1% tolerance, representing a compromise between the original ±0.25% specification and the ±0.05% alternatives. Active product status and adequate inventory (936 Pcs) support component procurement. All automotive and compliance certifications remain equivalent.

All three substitute parts are direct functional replacements with no circuit redesign or board layout modification required.

Frequently Asked Questions (FAQ)

Q: Can RG2012N-680-W-T1 be used as a direct replacement for RG2012N-680-C-T5?

A: Yes. Both components share identical resistance (68 Ohms), power rating (0.125W), package (0805), temperature coefficient (±10ppm/°C), operating range (-55°C to 155°C), and AEC-Q200 qualification. The RG2012N-680-W-T1 features tighter tolerance (±0.05% versus ±0.25%), which is compatible with all applications requiring the original part. Physical dimensions and termination count are identical.

Q: What is the difference between RG2012N-680-W-T1 and RG2012N-680-W-T5?

A: Both parts are electrically and mechanically identical. The difference lies in tape reel configuration: T1 and T5 designations indicate different reel specifications for automated pick-and-place equipment. Selection depends on your assembly equipment compatibility. Consult equipment documentation or supplier specifications for reel format requirements.

Q: Why is RG2012N-680-C-T5 marked as obsolete?

A: The RG2012N-680-C-T5 has been discontinued by the manufacturer. The substitute parts (RG2012N-680-B-T5, RG2012N-680-W-T1, RG2012N-680-W-T5) are active products offering equivalent or superior performance specifications and ensure continued supply availability.

Q: Are all substitute parts AEC-Q200 qualified?

A: Yes. All substitute parts listed carry AEC-Q200 automotive qualification, anti-sulfur coating, and ROHS3 compliance identical to the original component. These certifications are maintained across all alternatives.

Q: Can I use RG2012N-680-B-T5 if the tighter tolerance alternatives are unavailable?

A: Yes. The RG2012N-680-B-T5 provides ±0.1% tolerance, which is tighter than the original ±0.25% specification. This part is fully compatible with all electrical and mechanical requirements. Use this option when RG2012N-680-W-T1 or RG2012N-680-W-T5 are not available.

Q: Do these substitute parts require any PCB layout or schematic modifications?

A: No. All substitute parts maintain identical package dimensions (0805/2012 Metric), footprint, and electrical characteristics. Direct board-level substitution is possible without design changes.

Q: What is the MSL rating for these components?

A: All parts, including the original and substitutes, carry MSL 1 (Unlimited) rating. This indicates unlimited shelf life under normal storage conditions with no moisture sensitivity concerns.
