Key Parameters

Substitute Part Grouping Explanation

Substitution of the RG2012V-121-C-T5 is determined by strict equivalence across the following critical parameters:

Mandatory Equivalence Parameters:

• Resistance value: 120 Ohms (exact match required)
• Power rating: 0.125W (1/8W) (exact match required)
• Package type: 0805 (2012 Metric) (exact match required)
• Composition: Thin Film (exact match required)
• Temperature coefficient: ±5ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)
• Automotive qualification: AEC-Q200 (exact match required)
• Anti-sulfur construction (exact match required)

Variable Parameter (Substitution Basis):

• Tolerance specification: Substitute parts offer improved tolerance grades (±0.1%, ±0.05%, ±0.02%) compared to the main part (±0.25%). Tighter tolerance specifications are electrically and mechanically compatible with applications designed for ±0.25% tolerance.

All substitute parts maintain identical physical dimensions, termination count, RoHS3 compliance, MSL rating, and REACH status as the main part.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitution Candidates:

The RG2012V-121-B-T5, RG2012V-121-P-T1, RG2012V-121-W-T1, and RG2012V-121-W-T5 are direct functional equivalents to the obsolete RG2012V-121-C-T5. All substitute parts maintain active product status within the Susumu RG series and carry identical AEC-Q200 automotive qualification and ROHS3 compliance certifications.

Selection Based on Tolerance Requirements:

• RG2012V-121-B-T5 (±0.1% tolerance): Suitable for applications requiring improved tolerance performance over the original ±0.25% specification while maintaining cost-effectiveness.

• RG2012V-121-W-T1 and RG2012V-121-W-T5 (±0.05% tolerance): Appropriate for precision circuit applications demanding tighter tolerance control than the original part.

• RG2012V-121-P-T1 (±0.02% tolerance): Specified for high-precision measurement and calibration circuits requiring the tightest tolerance grade available within this product family.

All substitute parts are mechanically and electrically interchangeable with the main part across the full operating temperature range and maintain identical power dissipation characteristics, package footprint, and environmental compliance ratings.

Frequently Asked Questions (FAQ)

Q: Can RG2012V-121-B-T5, RG2012V-121-P-T1, RG2012V-121-W-T1, and RG2012V-121-W-T5 be used as direct replacements for RG2012V-121-C-T5?

A: Yes. All substitute parts are direct functional equivalents. They maintain identical resistance value (120 Ohms), power rating (0.125W), package type (0805), composition (thin film), temperature coefficient (±5ppm/°C), operating temperature range (-55°C to 155°C), and AEC-Q200 automotive qualification. The substitute parts offer improved tolerance specifications, which are compatible with applications designed for the original ±0.25% tolerance.

Q: What is the difference between the substitute parts?

A: The substitute parts differ only in tolerance specification. RG2012V-121-B-T5 provides ±0.1% tolerance, RG2012V-121-W-T1 and RG2012V-121-W-T5 provide ±0.05% tolerance, and RG2012V-121-P-T1 provides ±0.02% tolerance. All other electrical and mechanical parameters remain identical.

Q: Are there packaging differences between the substitute parts?

A: The main part (RG2012V-121-C-T5) is supplied in bulk packaging. All substitute parts are supplied in Tape & Reel (TR) packaging. The physical component dimensions and footprint remain identical across all parts.

Q: Do all substitute parts maintain AEC-Q200 automotive qualification?

A: Yes. All substitute parts carry AEC-Q200 automotive qualification and anti-sulfur construction, identical to the main part. All parts are ROHS3 compliant with MSL rating of 1 (Unlimited).

Q: Which substitute part should be selected for general replacement applications?

A: RG2012V-121-B-T5 (±0.1% tolerance) provides a balanced upgrade path, offering improved tolerance performance while maintaining cost-effectiveness. For applications with no specific tolerance requirement beyond the original ±0.25% specification, this part is the standard replacement choice.

Q: Can substitute parts be used in high-temperature automotive applications?

A: Yes. All substitute parts maintain the full operating temperature range of -55°C to 155°C and carry AEC-Q200 automotive qualification, identical to the main part. They are suitable for automotive and industrial applications across the specified temperature range.
