Key Parameters

Substitute Part Grouping Explanation

Substitution of the RG2012N-1213-C-T5 is determined by the following critical parameters that must remain constant or improve:

Mandatory Compatibility Parameters:

• Resistance value: 121 kOhms (exact match required)
• Package / Case: 0805 (2012 Metric) (exact match required)
• Composition: Thin Film (exact match required)
• Temperature Coefficient: ±10ppm/°C (exact match required)
• Automotive Rating: AEC-Q200 (exact match required)
• Anti-Sulfur Feature: Required (exact match required)

Allowable Substitution Parameters:

• Tolerance: May be equal or tighter (lower tolerance value acceptable)
• Power Rating: May be equal or higher (higher power rating acceptable)
• Operating Temperature Range: May be equal or extended (higher maximum temperature acceptable)
• Product Status: Active status preferred over obsolete

All substitute parts listed maintain identical mechanical dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm) and electrical core specifications while offering enhanced tolerance or power handling capabilities.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Susumu RG Series):

The RG2012N-1213-B-T5, RG2012N-1213-W-T1, and RG2012N-1213-W-T5 are direct substitutes manufactured by Susumu within the same RG series. All three parts are active products with identical mechanical and thermal specifications to the RG2012N-1213-C-T5. The primary differentiation is tolerance specification:

• RG2012N-1213-B-T5 offers ±0.1% tolerance (tighter than original ±0.25%)
• RG2012N-1213-W-T1 and RG2012N-1213-W-T5 offer ±0.05% tolerance (significantly tighter than original)

Selection among these three Susumu alternatives depends on tolerance requirements of the application circuit. The W-series parts (W-T1 and W-T5) provide superior tolerance performance for precision applications. The B-series part (B-T5) provides intermediate tolerance improvement with active product status.

Cross-Manufacturer Substitute (Vishay Dale):

The TNPW0805121KBYEA from Vishay Dale is a cross-manufacturer substitute that maintains all critical electrical parameters and AEC-Q200 automotive qualification. This part offers enhanced power rating (0.26W versus 0.125W) and extended operating temperature range (-55°C ~ 175°C versus -55°C ~ 155°C). The TNPW0805121KBYEA is suitable for applications requiring higher thermal margin or extended temperature operation while maintaining ±0.1% tolerance specification.

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and automotive-grade construction with anti-sulfur treatment.

Frequently Asked Questions (FAQ)

Q: Can the RG2012N-1213-C-T5 be directly replaced with any of the listed substitutes?

A: Yes. All listed substitute parts maintain identical resistance value (121 kOhms), package size (0805 / 2012 Metric), thin film composition, temperature coefficient (±10ppm/°C), and AEC-Q200 automotive qualification. Mechanical and electrical compatibility is confirmed for direct substitution in existing PCB layouts.

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

A: The three Susumu alternatives differ only in tolerance specification. RG2012N-1213-C-T5 (original) specifies ±0.25% tolerance. RG2012N-1213-B-T5 provides ±0.1% tolerance. RG2012N-1213-W-T1 and RG2012N-1213-W-T5 both provide ±0.05% tolerance. All other electrical and mechanical parameters remain identical. Selection should be based on circuit tolerance requirements.

Q: Why is the TNPW0805121KBYEA listed as a substitute if it has different power rating and temperature range?

A: The TNPW0805121KBYEA maintains all mandatory compatibility parameters: 121 kOhms resistance, 0805 package, thin film composition, ±10ppm/°C temperature coefficient, and AEC-Q200 rating. The higher power rating (0.26W versus 0.125W) and extended temperature range (-55°C ~ 175°C versus -55°C ~ 155°C) represent performance enhancements that do not compromise compatibility. These characteristics make it suitable for applications with higher thermal stress or extended temperature operation.

Q: Are there any packaging differences between the main part and substitutes?

A: The main part RG2012N-1213-C-T5 is specified with standard packaging (not explicitly detailed). All Susumu substitutes (RG2012N-1213-B-T5, RG2012N-1213-W-T1, RG2012N-1213-W-T5) are supplied in Tape & Reel (TR) packaging. The Vishay Dale TNPW0805121KBYEA is also supplied in Tape & Reel (TR) packaging. Physical dimensions remain constant across all parts: 0.079" L x 0.049" W (2.00mm x 1.25mm) with maximum seated height of 0.020" to 0.022".

Q: What is the significance of the product status change from Obsolete to Active?

A: The RG2012N-1213-C-T5 is classified as obsolete, indicating discontinued production and potential supply constraints. All listed substitutes are active products with confirmed current inventory availability. Selection of an active substitute ensures long-term supply chain reliability and continued component availability for production and field service applications.

Q: Can tolerance be tightened without affecting circuit performance?

A: Tighter tolerance specifications (lower tolerance values) provide improved resistance accuracy and reduced variation across production batches. In circuits where the original ±0.25% tolerance was specified, substitution with ±0.1% or ±0.05% tolerance parts will not degrade performance and may improve circuit precision. However, circuit design should be reviewed to confirm that tighter tolerance does not introduce unintended performance changes in feedback networks or precision measurement circuits.

Q: Are all substitutes suitable for automotive applications?

A: Yes. All listed substitute parts carry AEC-Q200 automotive qualification, anti-sulfur construction, and ROHS3 compliance. All parts are rated for the automotive temperature range of -55°C to at least 155°C. The TNPW0805121KBYEA extends this range to 175°C. All parts are suitable for automotive applications meeting or exceeding the original part's automotive specifications.
