Key Parameters

Substitute Part Grouping Explanation

Substitution of the RG2012N-364-B-T1 is determined by the following critical parameters:

Electrical Parameters:

• Resistance value: 360 kOhms (exact match required)
• Tolerance: ±0.1% or tighter (±0.05% acceptable as upgrade)
• Temperature coefficient: ±10ppm/°C (exact match)
• Power rating: 0.125W minimum (higher ratings acceptable)

Mechanical Parameters:

• Package: 0805 (2012 Metric) form factor (exact match required)
• Physical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm)
• Height seated maximum: 0.020" to 0.022" (0.50mm to 0.55mm)

Compliance & Environmental:

• Automotive AEC-Q200 qualification (required)
• Anti-sulfur coating (required)
• RoHS3 compliance (required)
• Moisture Sensitivity Level 1 (required)
• Operating temperature range: -55°C minimum to 155°C minimum

Packaging Format:

• Original packaging format (bulk vs. tape & reel) does not affect electrical or mechanical substitution

Substitute parts meeting all electrical, mechanical, and compliance criteria are classified as direct equivalents. Parts with improved tolerance specifications (±0.05%) are classified as upgrades while maintaining full backward compatibility.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Same Specifications):

RG2012N-364-B-T5 is a direct equivalent to RG2012N-364-B-T1. Both components share identical electrical specifications (360 kOhms ±0.1%, 0.125W, ±10ppm/°C) and mechanical form factor (0805 package). The primary difference is packaging format (tape & reel vs. bulk). RG2012N-364-B-T5 is currently in active production status, making it the primary replacement for the obsolete RG2012N-364-B-T1.

Upgraded Equivalent (Improved Tolerance):

RG2012N-364-W-T1 and RG2012N-364-W-T5 are upgraded equivalents offering tighter tolerance specification (±0.05% vs. ±0.1%). Both maintain identical power rating (0.125W), temperature coefficient (±10ppm/°C), and operating temperature range (-55°C ~ 155°C). These parts are fully backward compatible with the original specification and provide enhanced precision for applications requiring tighter resistance tolerances. Both are in active production status.

Cross-Manufacturer Equivalent (Enhanced Power Rating):

TNPW0805360KBYEA (Vishay Dale) is a cross-manufacturer equivalent with enhanced power rating (0.26W vs. 0.125W) and extended operating temperature range (-55°C ~ 175°C vs. -55°C ~ 155°C). Electrical specifications match the original part (360 kOhms ±0.1%, ±10ppm/°C). Physical dimensions are compatible with 0805 package, with maximum seated height of 0.022" (0.55mm) versus 0.020" (0.50mm) for the original. This component includes moisture-resistant coating in addition to anti-sulfur protection. TNPW0805360KBYEA is in active production status.

All substitute parts maintain AEC-Q200 automotive qualification, ROHS3 compliance, and MSL 1 rating required for the original application.

Frequently Asked Questions (FAQ)

Q: Can RG2012N-364-B-T5 be used as a direct replacement for RG2012N-364-B-T1?

A: Yes. RG2012N-364-B-T5 is a direct equivalent with identical electrical and mechanical specifications. The only difference is packaging format (tape & reel). Both components are 360 kOhms ±0.1%, 0.125W, 0805 package with ±10ppm/°C temperature coefficient and AEC-Q200 qualification.

Q: What is the difference between the RG2012N-364-B series and RG2012N-364-W series?

A: The primary difference is tolerance specification. The B-series (RG2012N-364-B-T1 and RG2012N-364-B-T5) offers ±0.1% tolerance, while the W-series (RG2012N-364-W-T1 and RG2012N-364-W-T5) offers ±0.05% tolerance. All other electrical and mechanical parameters remain identical. The W-series represents an upgrade path for applications requiring tighter resistance tolerances.

Q: Is TNPW0805360KBYEA compatible with the original RG2012N-364-B-T1 in terms of physical dimensions?

A: Yes, TNPW0805360KBYEA is compatible with the 0805 package form factor. The maximum seated height is 0.022" (0.55mm) compared to 0.020" (0.50mm) for the original part. This 0.002" (0.05mm) difference is within typical PCB design tolerances for 0805 components and does not affect board-level compatibility.

Q: Can I use TNPW0805360KBYEA in place of RG2012N-364-B-T1 if my circuit requires only 0.125W power dissipation?

A: Yes. TNPW0805360KBYEA has a power rating of 0.26W, which exceeds the 0.125W requirement of the original circuit. Higher power ratings do not create compatibility issues; the component will operate within its specifications at lower power levels. The enhanced power rating provides additional design margin.

Q: Are all substitute parts automotive-qualified?

A: Yes. All substitute parts listed (RG2012N-364-B-T5, RG2012N-364-W-T1, RG2012N-364-W-T5, and TNPW0805360KBYEA) carry AEC-Q200 automotive qualification matching the original RG2012N-364-B-T1.

Q: What is the significance of the T1 and T5 suffixes in Susumu part numbers?

A: The T1 and T5 suffixes indicate packaging format. T1 denotes bulk packaging, while T5 denotes tape & reel (TR) packaging. Electrical and mechanical specifications are identical between T1 and T5 variants of the same base part number.

Q: Do all substitute parts meet RoHS3 and MSL 1 requirements?

A: Yes. All substitute parts are ROHS3 compliant and rated MSL 1 (Unlimited moisture sensitivity level), matching the environmental compliance profile of the original RG2012N-364-B-T1.
