Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RG2012N-182-B-T5 are classified based on the following substitution criteria:

Critical Parameters (Must Match):

• Resistance value: 1.8 kOhms
• Package / Case: 0805 (2012 Metric)
• Power rating: 0.125W (1/8W)
• Composition: Thin Film
• Operating temperature range: -55°C ~ 155°C
• Automotive rating: AEC-Q200
• RoHS compliance: ROHS3 Compliant

Variable Parameters (Allow Substitution):

• Tolerance: ±0.1%, ±0.05%, ±0.02%
• Temperature coefficient: ±10ppm/°C, ±5ppm/°C
• Manufacturer: Susumu, Panasonic Electronic Components
• Physical height variation: 0.50mm (Susumu), 0.60mm (Panasonic)

Substitutes are grouped into two categories: direct equivalents (matching tolerance and temperature coefficient) and upgrade substitutes (improved tolerance and/or temperature coefficient specifications).

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Same Tolerance and Temperature Coefficient):

ERA-6ARB182V (Panasonic Electronic Components) is a direct functional equivalent to RG2012N-182-B-T5. Both parts share identical electrical specifications: 1.8 kOhms resistance, ±0.1% tolerance, ±10ppm/°C temperature coefficient, and 0.125W power rating. Both are AEC-Q200 rated, ROHS3 compliant, and operate across -55°C to 155°C. The primary difference is seated height: ERA-6ARB182V measures 0.024" (0.60mm) compared to RG2012N-182-B-T5 at 0.020" (0.50mm). This height variation must be evaluated against PCB layout constraints and solder joint clearance requirements.

Upgrade Substitutes (Improved Tolerance):

RG2012N-182-W-T1 (Susumu) provides improved tolerance of ±0.05% while maintaining all other electrical and mechanical specifications identical to the main part, including ±10ppm/°C temperature coefficient and 0.020" seated height.

RG2012V-182-P-T1 (Susumu) offers the highest tolerance specification at ±0.02% with an improved temperature coefficient of ±5ppm/°C. This part is suitable for applications requiring enhanced precision and stability.

ERA-6ARW182V (Panasonic Electronic Components) provides ±0.05% tolerance with ±10ppm/°C temperature coefficient and 0.024" seated height, combining Panasonic sourcing with improved tolerance specifications.

All substitute parts maintain AEC-Q200 automotive qualification, ROHS3 compliance, and MSL 1 rating, ensuring compatibility with automotive and high-reliability applications.

Frequently Asked Questions (FAQ)

Q: Can RG2012N-182-B-T5 be replaced with ERA-6ARB182V?

A: Yes. ERA-6ARB182V is a direct equivalent with identical electrical specifications (1.8 kOhms, ±0.1% tolerance, ±10ppm/°C temperature coefficient, 0.125W). Both are AEC-Q200 rated and ROHS3 compliant. The seated height difference (0.024" vs 0.020") must be verified against PCB layout and clearance requirements.

Q: What is the difference between RG2012N-182-B-T5 and RG2012N-182-W-T1?

A: RG2012N-182-W-T1 provides improved tolerance of ±0.05% compared to ±0.1% in RG2012N-182-B-T5. All other specifications remain identical, including temperature coefficient (±10ppm/°C), power rating (0.125W), package (0805), and seated height (0.020").

Q: When should RG2012V-182-P-T1 be selected over RG2012N-182-B-T5?

A: RG2012V-182-P-T1 is selected when applications require enhanced precision and thermal stability. This part offers ±0.02% tolerance and ±5ppm/°C temperature coefficient compared to ±0.1% tolerance and ±10ppm/°C in RG2012N-182-B-T5. All other parameters remain compatible.

Q: Are all substitute parts automotive qualified?

A: Yes. All substitute parts listed (RG2012N-182-W-T1, RG2012V-182-P-T1, ERA-6ARB182V, ERA-6ARW182V) are AEC-Q200 rated and suitable for automotive applications.

Q: What is the impact of seated height variation between Susumu and Panasonic parts?

A: Susumu parts (RG2012N-182-B-T5, RG2012N-182-W-T1, RG2012V-182-P-T1) have a maximum seated height of 0.020" (0.50mm). Panasonic parts (ERA-6ARB182V, ERA-6ARW182V) have a maximum seated height of 0.024" (0.60mm). This 0.004" (0.10mm) difference must be evaluated against PCB design constraints, component clearance, and solder joint geometry.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All parts listed are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity level) and REACH unaffected status.

Q: Can ERA-6ARW182V be used as a direct replacement for RG2012N-182-B-T5?

A: ERA-6ARW182V is functionally compatible but not a direct equivalent. It provides improved tolerance (±0.05% vs ±0.1%) and maintains ±10ppm/°C temperature coefficient. The seated height is 0.024" (0.60mm) compared to 0.020" (0.50mm). Verify PCB layout compatibility before substitution.

Q: What certifications and compliance standards apply to all listed parts?

A: All parts are AEC-Q200 automotive qualified, ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. All parts have MSL 1 rating (unlimited moisture sensitivity).
