Key Parameters

Substitute Part Grouping Explanation

Substitution of the RG2012N-48R7-C-T5 is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Resistance value: 48.7 Ohms (exact match required)
• Package type: 0805 (2012 Metric) (physical and electrical footprint compatibility)
• Composition: Thin Film (electrical performance characteristics)
• Temperature Coefficient: ±10ppm/°C (thermal stability)
• Automotive AEC-Q200 rating (quality and reliability standard)
• RoHS3 compliance (regulatory requirement)

Allowable Variation Parameters:

• Tolerance: Can be equal to or tighter than ±0.25% (±0.1% or ±0.05% are acceptable upgrades)
• Power rating: Can be equal to or greater than 0.125W (higher power ratings provide design margin)
• Operating temperature range: Can be equal to or extended beyond -55°C ~ 155°C
• Packaging format: Tape & Reel (TR) is acceptable for the obsolete cut-tape format

All substitute parts listed maintain the mandatory parameters while offering improvements in tolerance specification and/or power rating.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Susumu RG Series):

The RG2012N-48R7-B-T5, RG2012N-48R7-W-T1, and RG2012N-48R7-W-T5 are direct Susumu RG series substitutes. All three parts are active products with identical resistance values, package specifications, and AEC-Q200 automotive qualification. The RG2012N-48R7-B-T5 offers ±0.1% tolerance, while both W-series variants (RG2012N-48R7-W-T1 and RG2012N-48R7-W-T5) provide tighter ±0.05% tolerance. These represent tolerance upgrades from the original ±0.25% specification while maintaining identical power ratings and thermal characteristics.

Alternative Substitute (Vishay Dale TNPW Series):

The TNPW080548R7BYEA is an active cross-manufacturer substitute from Vishay Dale. This component maintains all mandatory compatibility parameters including 48.7 Ohm resistance, 0805 package, thin film composition, ±10ppm/°C temperature coefficient, and AEC-Q200 automotive qualification. The TNPW080548R7BYEA provides a higher power rating of 0.26W (compared to 0.125W) and an extended operating temperature range to 175°C, offering additional design margin for thermal performance. Tolerance is specified at ±0.1%.

Selection Basis:

All substitute parts maintain compliance with RoHS3 regulations, REACH requirements, and automotive AEC-Q200 standards. The choice between Susumu and Vishay Dale variants depends on supply chain preferences and specific application thermal requirements. The higher power rating of the TNPW080548R7BYEA is suitable for applications requiring additional thermal headroom without package size increase.

Frequently Asked Questions (FAQ)

Q: Can the RG2012N-48R7-C-T5 be replaced with any of the listed substitutes without design modification?

A: Yes. All listed substitutes maintain the same 48.7 Ohm resistance value, 0805 package footprint, thin film composition, and AEC-Q200 automotive qualification. No PCB layout or schematic changes are required. The substitutes offer equal or improved tolerance specifications and thermal performance.

Q: What is the difference between the Susumu RG series substitutes?

A: The primary difference is tolerance specification. RG2012N-48R7-B-T5 provides ±0.1% tolerance, while RG2012N-48R7-W-T1 and RG2012N-48R7-W-T5 both provide ±0.05% tolerance. All three maintain identical power ratings (0.125W), operating temperature ranges (-55°C ~ 155°C), and other electrical characteristics. The W-T1 and W-T5 designations indicate different tape reel configurations but identical electrical performance.

Q: Why does the TNPW080548R7BYEA have a higher power rating?

A: The TNPW080548R7BYEA is rated for 0.26W compared to 0.125W in the original and Susumu substitutes. This higher power rating is an inherent characteristic of the Vishay Dale TNPW e3 series design and provides additional thermal margin in applications with higher current or power dissipation requirements. The 0805 package dimensions remain identical.

Q: Are there any compatibility issues with the 0805 package across manufacturers?

A: No. The 0805 (2012 Metric) package is a standardized IPC specification. All parts listed use identical package dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm) with compatible termination specifications. Physical and electrical footprint compatibility is guaranteed.

Q: What is the significance of the AEC-Q200 rating?

A: AEC-Q200 is the automotive electronics council qualification standard for passive components. All listed parts meet this standard, confirming suitability for automotive applications with specified reliability, temperature cycling, and environmental stress testing requirements.

Q: Can substitutes with tighter tolerance (±0.05% or ±0.1%) be used in place of the ±0.25% original?

A: Yes. Tighter tolerance specifications are direct upgrades that improve circuit accuracy and performance. Applications designed for ±0.25% tolerance will operate correctly with ±0.1% or ±0.05% components, as the actual resistance values remain within the original specification window.

Q: What is the difference between Tape & Reel (TR) packaging and the original format?

A: The original RG2012N-48R7-C-T5 was supplied in cut-tape format. All active substitutes are supplied in Tape & Reel (TR) format, which is the current industry standard for automated assembly. TR format is compatible with standard pick-and-place equipment and offers improved handling and storage characteristics. No functional difference exists between the components themselves.

Q: Is the extended temperature range of the TNPW080548R7BYEA (-55°C ~ 175°C) necessary?

A: The extended range to 175°C is not required for applications designed for the original -55°C ~ 155°C range. However, it provides additional thermal margin for applications operating near the upper temperature limit or experiencing thermal cycling stress. Selection depends on specific application thermal requirements.
