Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RG2012N-272-B-T5 is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Resistance value: 2.7 kOhms (exact match required)
• Package / Case: 0805 (2012 Metric) (exact match required)
• Power rating: 0.125W minimum (equal or higher acceptable)
• Composition: Thin Film (exact match required)
• Temperature coefficient: ±10ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C minimum (equal or wider acceptable)
• Automotive rating: AEC-Q200 (exact match required)
• RoHS compliance: ROHS3 (exact match required)

Tolerance Substitution Logic: Parts with tolerance of ±0.1% or tighter (±0.05%) are acceptable substitutes. The RG2012N-272-B-T5 with ±0.1% tolerance can be directly replaced by parts with equal or superior tolerance specifications.

Identified Substitute Categories:

1. Direct Equivalent (Same Tolerance): ERA-6ARB272V (Panasonic) — identical electrical specifications and tolerance
2. Upgrade Substitute (Tighter Tolerance): RG2012N-272-W-T1 (Susumu) and ERA-6ARW272V (Panasonic) — both feature ±0.05% tolerance, providing enhanced precision

All substitute parts maintain identical package dimensions, thermal characteristics, and automotive compliance ratings.

Parameter Comparison

Engineering Selection Recommendations

RG2012N-272-B-T5 (Primary Part) Select this part for applications requiring standard ±0.1% tolerance with anti-sulfur coating. All electrical and mechanical specifications meet automotive AEC-Q200 requirements. ROHS3 compliance and MSL 1 rating support unrestricted storage and handling. Active production status ensures supply availability.

RG2012N-272-W-T1 (Susumu Upgrade) This part provides tighter ±0.05% tolerance while maintaining identical package dimensions, thermal performance, and automotive compliance. Select when circuit design requires enhanced precision without changing component footprint or thermal characteristics. Susumu manufacturer continuity supports design consistency.

ERA-6ARB272V (Panasonic Direct Equivalent) This part matches the RG2012N-272-B-T5 tolerance specification (±0.1%) and provides equivalent electrical performance. Panasonic manufacturing ensures AEC-Q200 compliance and ROHS3 status. Maximum seated height of 0.024" (0.60mm) versus 0.020" (0.50mm) for Susumu parts requires PCB layout verification for height-constrained applications.

ERA-6ARW272V (Panasonic Upgrade) This part combines Panasonic manufacturing with ±0.05% tolerance for enhanced precision applications. Maximum seated height of 0.024" (0.60mm) requires clearance verification in compact assemblies. Select when both precision upgrade and Panasonic supply chain are required.

All substitute parts maintain identical resistance value, power rating, package footprint, temperature coefficient, and operating temperature range. Selection between Susumu and Panasonic manufacturers depends on supply chain requirements and PCB height constraints.

Frequently Asked Questions (FAQ)

Q: Can ERA-6ARB272V replace RG2012N-272-B-T5 directly? A: Yes. Both parts feature 2.7 kOhms resistance, ±0.1% tolerance, 0.125W power rating, 0805 package, thin film composition, ±10ppm/°C temperature coefficient, -55°C ~ 155°C operating range, and AEC-Q200 automotive rating. The maximum seated height differs (0.024" versus 0.020"), requiring verification that PCB clearance accommodates the Panasonic part.

Q: What is the difference between RG2012N-272-B-T5 and RG2012N-272-W-T1? A: Both are Susumu thin film 0805 resistors with identical 2.7 kOhms resistance and package specifications. The primary difference is tolerance: RG2012N-272-B-T5 specifies ±0.1%, while RG2012N-272-W-T1 specifies ±0.05%. The tighter tolerance of RG2012N-272-W-T1 provides enhanced precision for applications requiring stricter resistance accuracy. Both maintain identical package height (0.020" maximum seated).

Q: Are all substitute parts AEC-Q200 qualified? A: Yes. RG2012N-272-B-T5, RG2012N-272-W-T1, ERA-6ARB272V, and ERA-6ARW272V all carry AEC-Q200 automotive qualification, confirming suitability for automotive and high-reliability applications.

Q: Can I use ERA-6ARW272V as a substitute for RG2012N-272-B-T5? A: Yes. ERA-6ARW272V meets all mandatory compatibility parameters: 2.7 kOhms resistance, 0805 package, 0.125W power rating, thin film composition, ±10ppm/°C temperature coefficient, -55°C ~ 155°C operating range, and AEC-Q200 rating. The ±0.05% tolerance is tighter than the ±0.1% requirement, providing enhanced precision. Maximum seated height of 0.024" requires PCB clearance verification.

Q: What is the significance of the ±0.1% and ±0.05% tolerance specifications? A: Tolerance defines the maximum allowable deviation of the actual resistance value from the nominal 2.7 kOhms specification. ±0.1% tolerance allows deviation up to ±2.7 ohms, while ±0.05% tolerance restricts deviation to ±1.35 ohms. Applications requiring tighter resistance accuracy benefit from ±0.05% parts. Both tolerances are acceptable for standard circuit applications; selection depends on design precision requirements.

Q: Are there height constraints when substituting between Susumu and Panasonic parts? A: Yes. Susumu RG2012N-272-B-T5 and RG2012N-272-W-T1 specify maximum seated height of 0.020" (0.50mm). Panasonic ERA-6ARB272V and ERA-6ARW272V specify maximum seated height of 0.024" (0.60mm). In PCB designs with height-constrained clearances, verify that the 0.004" (0.10mm) additional height of Panasonic parts does not violate assembly or enclosure requirements.

Q: Do all substitute parts have identical RoHS and REACH compliance? A: Yes. All four parts (RG2012N-272-B-T5, RG2012N-272-W-T1, ERA-6ARB272V, and ERA-6ARW272V) are ROHS3 compliant and REACH unaffected, supporting equivalent regulatory compliance for design substitution.

Q: What is the MSL rating and why is it relevant? A: All substitute parts carry MSL 1 (Unlimited) moisture sensitivity level, indicating no moisture absorption restrictions during storage or handling. This simplifies inventory management and eliminates the need for desiccant packaging or baking procedures prior to assembly.
