Key Parameters

Substitute Part Grouping Explanation

Substitution of the RG2012V-1180-B-T1 is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Resistance value: 118 Ohms (exact match required)
• Power rating: 0.125W minimum
• Temperature coefficient: ±5ppm/°C or better
• Operating temperature range: Must support -55°C to 155°C minimum

Mechanical Compatibility Requirements:

• Package type: 0805 (2012 Metric) form factor
• Physical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm)
• Number of terminations: 2

Regulatory & Compliance Requirements:

• Automotive AEC-Q200 qualification
• Anti-sulfur coating
• RoHS3 compliance
• Moisture Sensitivity Level 1

Tolerance Considerations: Substitute parts with equal or tighter tolerance specifications (±0.1%, ±0.05%, ±0.02%) are functionally interchangeable. Tighter tolerance variants provide enhanced precision for applications requiring stricter resistance accuracy.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Same Tolerance): RG2012V-1180-B-T5 is the direct active equivalent to the obsolete RG2012V-1180-B-T1. Both components share identical electrical specifications (118 Ohms ±0.1%, 0.125W, ±5ppm/°C) and mechanical form factor (0805). The primary difference is packaging format (Tape & Reel vs. bulk) and active product status. This part is the recommended primary substitute.

TNPU0805118RBZEN00 (Vishay Dale) provides equivalent electrical performance with identical tolerance (±0.1%) and power rating. This cross-manufacturer option maintains AEC-Q200 compliance and anti-sulfur coating. Operating temperature range extends to -55°C to 125°C, which covers the lower end of the original specification but does not reach the 155°C maximum. Selection of this part requires confirmation that the application does not require operation above 125°C.

Enhanced Tolerance Variants (Tighter Specifications): RG2012V-1180-W-T1 and RG2012V-1180-W-T5 offer ±0.05% tolerance, providing twice the precision of the original specification. These parts are suitable for applications requiring improved resistance accuracy while maintaining all other electrical and mechanical parameters.

RG2012V-1180-P-T1 provides the tightest tolerance at ±0.02%, delivering five times greater precision than the original part. This variant is applicable to precision measurement and calibration circuits where enhanced accuracy is required.

All Susumu variants maintain the full -55°C to 155°C operating temperature range and are active products with confirmed inventory availability.

Frequently Asked Questions (FAQ)

Q: Can RG2012V-1180-B-T5 be used as a direct replacement for RG2012V-1180-B-T1?

A: Yes. Both parts are electrically and mechanically identical, with 118 Ohms ±0.1% resistance, 0.125W power rating, 0805 package, and identical temperature characteristics. The primary difference is packaging format (Tape & Reel vs. bulk) and product status (Active vs. Obsolete). RG2012V-1180-B-T5 is the recommended direct substitute.

Q: What is the difference between the tolerance grades (B, W, P)?

A: The tolerance grades indicate resistance accuracy: B-grade = ±0.1%, W-grade = ±0.05%, P-grade = ±0.02%. All three grades share identical 118 Ohm nominal value, power rating, and temperature coefficient. Selection depends on circuit accuracy requirements. Tighter tolerance parts are suitable for precision applications but may have different cost implications.

Q: Is TNPU0805118RBZEN00 fully compatible with RG2012V-1180-B-T1?

A: TNPU0805118RBZEN00 is electrically compatible with identical 118 Ohm ±0.1% specifications and 0805 package. Both parts carry AEC-Q200 qualification and anti-sulfur coating. The operating temperature range differs: TNPU0805118RBZEN00 operates from -55°C to 125°C, while the original part extends to 155°C. Compatibility depends on whether the application requires operation above 125°C.

Q: Can I substitute a higher tolerance part (±0.05% or ±0.02%) for the original ±0.1% specification?

A: Yes. Tighter tolerance parts (lower tolerance values) are functionally interchangeable with looser tolerance specifications. A ±0.05% part will meet all requirements of a ±0.1% application. This substitution improves circuit accuracy without compromising compatibility.

Q: What does the T1 and T5 suffix indicate?

A: The T1 and T5 suffixes denote packaging format. T1 indicates standard Tape & Reel packaging, while T5 indicates alternative Tape & Reel configuration. Both formats are suitable for automated assembly processes. Selection depends on manufacturing equipment compatibility and supply chain requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts maintain RoHS3 compliance and Moisture Sensitivity Level 1 (Unlimited), matching the original part's environmental and regulatory status.

Q: Which substitute part should I select for new designs?

A: For new designs requiring direct electrical equivalence, select RG2012V-1180-B-T5 (Susumu, ±0.1% tolerance, active status). For applications requiring enhanced precision, select RG2012V-1180-W-T1 (±0.05%) or RG2012V-1180-P-T1 (±0.02%). For cross-manufacturer sourcing, TNPU0805118RBZEN00 (Vishay Dale) is suitable provided operating temperature does not exceed 125°C.
