Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RG2012P-184-B-T5 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 180 kOhms
• Package / Case: 0805 (2012 Metric)
• Power rating: 0.125W (1/8W)
• Operating temperature range: -55°C ~ 155°C
• Composition: Thin Film
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

Allowable Variation Parameters:

• Tolerance: ±0.1% or tighter (±0.05%)
• Temperature coefficient: ±25ppm/°C or tighter (±10ppm/°C)
• Automotive rating: AEC-Q200 (required for direct substitution)
• Manufacturer: Different manufacturers acceptable if all parameters align

The identified substitute parts meet all mandatory matching parameters. Tolerance and temperature coefficient improvements represent performance enhancements rather than deviations from specification.

Parameter Comparison

Engineering Selection Recommendations

RG2012N-184-W-T1 and RG2012N-184-W-T5 (Susumu)

Both parts are direct Susumu alternatives with improved tolerance specification (±0.05% versus ±0.1%) and superior temperature coefficient (±10ppm/°C versus ±25ppm/°C). Both maintain AEC-Q200 automotive qualification and ROHS3 compliance. The RG2012N-184-W-T5 variant offers higher inventory availability (6036 pieces) compared to RG2012N-184-W-T1 (2850 pieces). These parts are suitable for applications requiring tighter tolerance control while maintaining identical package footprint and power rating.

ERA-6AEB184V (Panasonic Electronic Components)

This part provides equivalent electrical specifications matching the main part exactly (±0.1% tolerance, ±25ppm/°C temperature coefficient) with AEC-Q200 automotive qualification. The ERA-6AEB184V maintains identical resistance, power rating, and operating temperature range. Height specification is 0.024" (0.60mm) compared to 0.020" (0.50mm) for the main part. This represents a 0.004" (0.10mm) increase in seated height. Panasonic qualification and ROHS3 compliance are confirmed. Inventory availability is 9290 pieces.

RT0805BRD07180KL (YAGEO)

This part matches electrical specifications (±0.1% tolerance, ±25ppm/°C temperature coefficient) and package dimensions identically to the main part. The RT0805BRD07180KL is ROHS3 compliant with MSL 1 rating. Automotive AEC-Q200 rating is not specified for this part. Height specification is 0.024" (0.60mm). Inventory availability is 9262 pieces, representing the highest stock level among all alternatives.

Frequently Asked Questions (FAQ)

Q: Can RG2012N-184-W-T1 and RG2012N-184-W-T5 be used interchangeably with RG2012P-184-B-T5?

A: Yes. Both parts share identical resistance (180 kOhms), power rating (0.125W), package (0805), and operating temperature range (-55°C ~ 155°C). The RG2012N variants offer improved tolerance (±0.05%) and temperature coefficient (±10ppm/°C) specifications. Both maintain AEC-Q200 automotive qualification and ROHS3 compliance. Seated height is identical at 0.020" (0.50mm).

Q: What is the difference between RG2012N-184-W-T1 and RG2012N-184-W-T5?

A: Both parts are electrically and mechanically identical. The designation difference reflects packaging reel specifications (T1 versus T5). RG2012N-184-W-T5 has higher inventory availability (6036 pieces versus 2850 pieces).

Q: Can ERA-6AEB184V replace RG2012P-184-B-T5 in space-constrained applications?

A: ERA-6AEB184V has a seated height of 0.024" (0.60mm) compared to 0.020" (0.50mm) for the main part. This 0.004" (0.10mm) height difference must be evaluated against specific PCB layout constraints. All other dimensions and electrical specifications are compatible.

Q: Is RT0805BRD07180KL suitable for automotive applications?

A: RT0805BRD07180KL meets the electrical and package specifications of the main part. However, AEC-Q200 automotive qualification is not specified for this part. Applications requiring explicit automotive qualification should use RG2012P-184-B-T5, RG2012N-184-W-T1, RG2012N-184-W-T5, or ERA-6AEB184V.

Q: What tolerance specification should be selected for precision circuit applications?

A: RG2012N-184-W-T1 and RG2012N-184-W-T5 provide ±0.05% tolerance with ±10ppm/°C temperature coefficient. These specifications are tighter than the main part (±0.1% tolerance, ±25ppm/°C). Selection depends on circuit accuracy requirements and cost considerations.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All identified substitute parts (RG2012N-184-W-T1, RG2012N-184-W-T5, ERA-6AEB184V, and RT0805BRD07180KL) are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level.

Q: What is the impact of different seated heights on PCB assembly?

A: RG2012P-184-B-T5, RG2012N-184-W-T1, and RG2012N-184-W-T5 have seated height of 0.020" (0.50mm). ERA-6AEB184V and RT0805BRD07180KL have seated height of 0.024" (0.60mm). This 0.004" (0.10mm) difference affects clearance calculations for conformal coating, potting, or mechanical assembly. PCB design files should be reviewed to confirm compatibility.
