Key Parameters

Substitute Part Grouping Explanation

Substitution of the RG2012P-182-W-T1 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 1.8 kOhms
• Package type: 0805 (2012 Metric)
• Power rating: 0.125W (1/8W)
• Composition: Thin Film
• Operating temperature range: -55°C to 155°C
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

Allowable Variation Parameters:

• Tolerance: ±0.05% or tighter (±0.02%)
• Temperature coefficient: ±5ppm/°C to ±25ppm/°C
• Automotive rating: AEC-Q200 (required for automotive applications)
• Packaging format: Tape & Reel (TR) or Cut Tape (CT) acceptable
• Manufacturer: Susumu, Panasonic Electronic Components, or YAGEO

Substitutes are grouped into three categories: direct equivalents (identical specifications), upgrades (improved tolerance or temperature coefficient), and similar parts (relaxed tolerance specifications).

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Packaging Format Change Only): RG2012P-182-W-T5 is the direct equivalent of RG2012P-182-W-T1, differing only in packaging format (Tape & Reel versus bulk). Both maintain identical electrical specifications: 1.8 kOhms ±0.05% tolerance, ±25ppm/°C temperature coefficient, and AEC-Q200 automotive qualification. This part is active and recommended for immediate substitution.

Upgraded Susumu Alternatives (Improved Temperature Coefficient): RG2012V-182-W-T1 and RG2012V-182-W-T5 offer improved temperature stability with ±5ppm/°C coefficient compared to the original ±25ppm/°C. Both maintain ±0.05% tolerance and AEC-Q200 rating. These parts are active and suitable for applications requiring enhanced thermal performance.

RG2012N-182-W-T5 provides intermediate temperature coefficient performance (±10ppm/°C) while maintaining all other specifications. This part is active and available in Tape & Reel format.

Upgraded Susumu Alternative (Improved Tolerance): RG2012V-182-P-T1 offers tighter tolerance (±0.02%) and superior temperature coefficient (±5ppm/°C). This part is active and recommended for precision applications requiring enhanced accuracy.

Cross-Manufacturer Alternatives: ERA-6ARW182V (Panasonic) and RT0805WRB071K8L (YAGEO) provide equivalent specifications with ±0.05% tolerance and ±10ppm/°C temperature coefficient. Both are AEC-Q200 rated and active. Panasonic part features anti-sulfur coating consistent with original design. YAGEO part does not specify anti-sulfur feature.

Similar Part (Relaxed Tolerance): ERA-6AEB182V (Panasonic) maintains AEC-Q200 rating but features relaxed tolerance (±0.1%) and ±25ppm/°C temperature coefficient. This part is suitable only for applications where ±0.1% tolerance is acceptable. Available in Cut Tape & Digi-Reel format.

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and -55°C to 155°C operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can RG2012P-182-W-T5 replace RG2012P-182-W-T1 directly? A: Yes. RG2012P-182-W-T5 is electrically and mechanically identical to RG2012P-182-W-T1. The only difference is packaging format (Tape & Reel versus bulk). Both parts share identical resistance, tolerance, power rating, temperature coefficient, and AEC-Q200 automotive qualification.

Q: What is the difference between RG2012V and RG2012N series? A: The RG2012V series features ±5ppm/°C temperature coefficient, while RG2012N series features ±10ppm/°C. Both maintain ±0.05% tolerance and AEC-Q200 rating. Selection depends on thermal stability requirements of the application.

Q: Can I use ERA-6AEB182V as a substitute? A: ERA-6AEB182V is suitable only if your application accepts ±0.1% tolerance. The original RG2012P-182-W-T1 specifies ±0.05% tolerance. ERA-6AEB182V also features ±25ppm/°C temperature coefficient matching the original. Verify tolerance requirements before substitution.

Q: Are all substitute parts AEC-Q200 rated? A: All Susumu RG series and Panasonic ERA-6A series parts listed are AEC-Q200 rated. YAGEO RT0805WRB071K8L does not specify AEC-Q200 rating in provided data. Confirm automotive qualification requirements before selecting YAGEO part.

Q: What is the significance of anti-sulfur coating? A: Anti-sulfur coating protects resistor terminations from sulfur-induced corrosion in harsh environments. Susumu RG series and Panasonic ERA-6ARW182V feature this coating. ERA-6AEB182V and YAGEO RT0805WRB071K8L do not specify this feature. Select anti-sulfur variants for applications in corrosive environments.

Q: Can I mix packaging formats in production? A: Tape & Reel (TR) and Cut Tape (CT) formats are compatible with standard pick-and-place equipment. Bulk packaging requires manual handling. Verify your assembly process compatibility before selecting packaging format.

Q: What does MSL 1 (Unlimited) mean? A: MSL 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. All listed parts maintain MSL 1 rating.

Q: Are there height differences between substitute parts? A: RG2012P-182-W-T1 specifies maximum seated height of 0.020" (0.50mm). ERA-6ARW182V, RT0805WRB071K8L, and ERA-6AEB182V specify 0.024" (0.60mm). Verify PCB clearance requirements for components with increased height.
