Key Parameters

Substitute Part Grouping Explanation

Substitution of the RG2012N-3163-C-T5 is determined by the following critical parameters that must remain constant or improve:

Mandatory Compatibility Parameters:

• Resistance value: 316 kOhms (exact match required)
• Package type: 0805 (2012 Metric) (exact match required)
• Composition: Thin Film (exact match required)
• Automotive rating: AEC-Q200 (exact match required)
• Temperature coefficient: ±10ppm/°C (exact match required)

Allowable Variation 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 characteristics except where explicitly improved. Substitutes are grouped by tolerance specification, representing performance upgrades from the original ±0.25% tolerance.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Susumu RG Series):

The RG2012N-3163-B-T5, RG2012N-3163-W-T1, and RG2012N-3163-W-T5 are direct Susumu replacements maintaining identical mechanical and thermal specifications. All three are active products with ROHS3 compliance and AEC-Q200 automotive qualification. The RG2012N-3163-B-T5 offers ±0.1% tolerance improvement over the original ±0.25% specification. The RG2012N-3163-W-T1 and RG2012N-3163-W-T5 provide the highest tolerance specification at ±0.05%, representing the tightest tolerance available within this product family. Selection between these three Susumu alternatives depends on tolerance requirements for the specific application circuit.

Cross-Manufacturer Substitute (Vishay Dale):

The TNPW0805316KBYEA from Vishay Dale provides an alternative from a different manufacturer while maintaining 316 kOhms resistance, ±0.1% tolerance, and AEC-Q200 qualification. This part offers enhanced power rating capability at 0.26W compared to the 0.125W rating of the original and Susumu alternatives, and extends the maximum operating temperature to 175°C. The TNPW0805316KBYEA includes moisture-resistant construction in addition to anti-sulfur features. Physical dimensions remain identical to the original 0805 package specification.

Compliance and Availability:

All substitute parts maintain ROHS3 compliance, REACH unaffected status, and MSL 1 (unlimited) moisture sensitivity rating. All are currently in active production status with confirmed inventory availability, eliminating obsolescence concerns associated with the original RG2012N-3163-C-T5.

Frequently Asked Questions (FAQ)

Q: Can the RG2012N-3163-B-T5 be used as a direct replacement for the RG2012N-3163-C-T5?

A: Yes. The RG2012N-3163-B-T5 maintains identical resistance (316 kOhms), package (0805), power rating (0.125W), temperature coefficient (±10ppm/°C), operating temperature range (-55°C ~ 155°C), and AEC-Q200 automotive qualification. The tolerance is improved from ±0.25% to ±0.1%, which is a performance enhancement compatible with all applications accepting the original part.

Q: What is the difference between the RG2012N-3163-W-T1 and RG2012N-3163-W-T5?

A: Both parts are identical in all electrical and mechanical specifications. Both offer 316 kOhms resistance at ±0.05% tolerance, 0.125W power rating, and 0805 package. The designation difference (T1 versus T5) reflects different tape and reel packaging configurations. Selection between these two depends on packaging and handling requirements rather than electrical performance.

Q: Why does the TNPW0805316KBYEA have a higher power rating than the original part?

A: The TNPW0805316KBYEA is rated for 0.26W power dissipation compared to the 0.125W rating of the RG2012N-3163-C-T5, despite identical 0805 package dimensions. This reflects different thermal design and material composition between manufacturers. The higher power rating does not affect compatibility; the part operates safely at the original 0.125W specification and provides additional thermal margin for applications requiring higher power dissipation.

Q: Are all substitute parts suitable for automotive applications?

A: Yes. All substitute parts listed carry AEC-Q200 automotive qualification identical to the original RG2012N-3163-C-T5. All include anti-sulfur construction and are ROHS3 compliant. The TNPW0805316KBYEA additionally includes moisture-resistant construction and extends the maximum operating temperature to 175°C, providing enhanced environmental protection for demanding automotive applications.

Q: Can I mix different substitute parts in the same circuit board assembly?

A: Yes. All substitute parts maintain identical resistance value (316 kOhms), package (0805), temperature coefficient (±10ppm/°C), and operating temperature range (-55°C ~ 155°C). Tolerance specifications vary (±0.25%, ±0.1%, or ±0.05%), but tighter tolerance parts are functionally compatible with applications designed for looser tolerances. Circuit design should account for the tolerance specification of the part selected.

Q: What is the physical compatibility of these parts with the original 0805 package footprint?

A: All substitute parts maintain identical 0805 (2012 Metric) package dimensions of 0.079" L x 0.049" W (2.00mm x 1.25mm). The TNPW0805316KBYEA has a maximum seated height of 0.022" (0.55mm) compared to 0.020" (0.50mm) for the original and Susumu alternatives. This 0.002" (0.05mm) difference is within standard PCB assembly tolerances and does not affect footprint compatibility or reflow soldering processes.

Q: Is the RG2012N-3163-C-T5 still available for purchase?

A: The RG2012N-3163-C-T5 is classified as obsolete. All substitute parts listed are active products with confirmed current inventory availability. Procurement should transition to one of the active substitute parts to ensure continued supply chain access and eliminate obsolescence risk.
