Package type: 0805 (2012 Metric) (exact match required)
Power rating: 0.125W minimum (equal or higher acceptable)
Composition: Thin Film
Automotive qualification: AEC-Q200
Anti-sulfur construction

Allowable Variation Parameters:

Tolerance: ±0.25% or tighter (lower tolerance values are acceptable upgrades)
Temperature coefficient: ±10ppm/°C or better (lower values are acceptable upgrades)

Engineering Selection Recommendations

Susumu RG Series (Thin Film, ±10ppm/°C Temperature Coefficient):

The RG2012N-2610-B-T5, RG2012N-2610-W-T1, and RG2012N-2610-W-T5 are direct functional equivalents from Susumu's active product line. These parts maintain identical temperature coefficient performance (±10ppm/°C) and operating temperature range (-55°C to 155°C) as the original RG2012N-2610-C-T5. All three parts feature improved tolerance specifications (±0.1% or ±0.05%) compared to the original ±0.25% tolerance. These parts are suitable for applications where the original tolerance specification is acceptable or where tighter tolerance is beneficial.

Susumu RG Series (Thin Film, ±5ppm/°C Temperature Coefficient):

The RG2012V-2610-B-T5, RG2012V-2610-P-T1, RG2012V-2610-W-T1, and RG2012V-2610-W-T5 represent enhanced performance variants with superior temperature coefficient stability (±5ppm/°C). These parts are suitable for applications requiring improved temperature stability and tighter tolerance control. All variants maintain the same operating temperature range and AEC-Q200 automotive qualification.

Vishay Dale TNPW Series (Thin Film, Higher Power Rating):

The TNPW0805261RBYEA is a cross-manufacturer substitute from Vishay Dale with identical 261 Ohm resistance and 0805 package footprint. This part features a higher power rating (0.26W versus 0.125W) and extended operating temperature range (-55°C to 175°C). The TNPW0805261RBYEA is suitable for applications where increased power dissipation capability or extended temperature operation is required. All parts maintain AEC-Q200 automotive qualification and ROHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can the RG2012N-2610-C-T5 be replaced with any of the listed substitute parts?

A: Yes. All listed substitute parts maintain the same 261 Ohm resistance value, 0805 package footprint, thin film composition, and AEC-Q200 automotive qualification. Mechanical and electrical compatibility is assured across all substitutes.

Q: What is the difference between the RG2012N and RG2012V series?

A: The primary difference is temperature coefficient performance. The RG2012N series has a temperature coefficient of ±10ppm/°C, while the RG2012V series has a superior temperature coefficient of ±5ppm/°C. Both series are thin film construction with anti-sulfur properties and AEC-Q200 qualification.

Q: Why does the TNPW0805261RBYEA have a higher power rating (0.26W) than the original part (0.125W)?

A: The TNPW0805261RBYEA is manufactured by Vishay Dale using different construction techniques that allow higher power dissipation in the same 0805 package size. This higher power rating does not affect compatibility; the part can be used in applications designed for 0.125W or lower power requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed are ROHS3 compliant with moisture sensitivity level 1 (unlimited), matching the environmental compliance profile of the original RG2012N-2610-C-T5.

Q: What tolerance should I select for my application?

A: Tolerance selection depends on circuit requirements. The original part specifies ±0.25%. Substitute parts with ±0.1%, ±0.05%, or ±0.02% tolerance are tighter specifications that provide improved accuracy. Select the tolerance that meets your circuit's precision requirements without over-specification.

Q: Can I use the TNPW0805261RBYEA in place of the Susumu parts?

A: Yes. The TNPW0805261RBYEA is mechanically and electrically compatible. It offers higher power dissipation capability and extended operating temperature range (to 175°C). Verify that the higher power rating and extended temperature range do not introduce unintended circuit behavior in your specific application.

Q: What is the difference between T1 and T5 packaging designations?

A: The T1 and T5 designations refer to different tape and reel packaging configurations used for automated assembly. Both are compatible with standard pick-and-place equipment. Selection between T1 and T5 depends on your manufacturing equipment specifications and supply chain requirements.
