Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RG2012N-3163-B-T1 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 316 kOhms
• Package type: 0805 (2012 Metric)
• Composition: Thin Film
• Automotive qualification: AEC-Q200
• RoHS compliance: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation Parameters:

• Tolerance: ±0.1% or tighter (±0.05%)
• Power rating: 0.125W or higher
• Temperature coefficient: ±10ppm/°C or tighter
• Operating temperature range: -55°C ~ 155°C or extended range
• Packaging format: Bulk or Tape & Reel (TR)
• Manufacturer: Different manufacturers acceptable if specifications align

Substitute parts must maintain identical electrical performance at the specified resistance value while meeting or exceeding the original part's precision, power handling, and environmental specifications.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Identical Specifications):

RG2012N-3163-B-T5 and ERA-6AEB3163V are direct functional equivalents to the RG2012N-3163-B-T1. Both maintain the 316 kOhms ±0.1% tolerance, 0.125W power rating, and AEC-Q200 automotive qualification. The primary difference is packaging format: RG2012N-3163-B-T5 is supplied in Tape & Reel format (active product status), while ERA-6AEB3163V is a Panasonic alternative with higher inventory availability (24,018 pcs). The ERA-6AEB3163V exhibits a higher temperature coefficient (±25ppm/°C versus ±10ppm/°C) but remains within acceptable automotive specifications.

Upgraded Substitutes (Enhanced Tolerance):

RG2012N-3163-W-T1 and RG2012N-3163-W-T5 offer tighter tolerance specifications (±0.05% versus ±0.1%), providing superior precision for applications requiring enhanced accuracy. These Susumu parts maintain identical power ratings, temperature coefficients, and operating ranges. The "-W" designation indicates the tighter tolerance grade.

Higher Power Rating Alternative:

TNPW0805316KBYEA (Vishay Dale) provides doubled power dissipation capability (0.26W versus 0.125W) while maintaining the 316 kOhms ±0.1% specification and AEC-Q200 qualification. This part extends the maximum operating temperature to 175°C and includes moisture-resistant coating. Selection of this part is appropriate for applications with elevated thermal requirements or higher current demands.

All substitute parts are ROHS3 compliant with MSL 1 rating and maintain compatibility with the original 0805 package footprint.

Frequently Asked Questions (FAQ)

Q: Can RG2012N-3163-B-T5 directly replace RG2012N-3163-B-T1 in production?

A: Yes. RG2012N-3163-B-T5 is electrically and mechanically identical to the original part. The primary difference is packaging format: RG2012N-3163-B-T5 is supplied in Tape & Reel (TR) format suitable for automated assembly, while the original was bulk packaged. Both maintain 316 kOhms ±0.1%, 0.125W power rating, and AEC-Q200 qualification.

Q: What is the difference between the "-W" and "-B" designations in Susumu part numbers?

A: The "-W" designation indicates a tighter tolerance grade (±0.05%) compared to the "-B" designation (±0.1%). Both maintain identical power ratings, temperature coefficients, and package specifications. Selection depends on circuit precision requirements.

Q: Is ERA-6AEB3163V suitable for applications requiring ±10ppm/°C temperature coefficient?

A: ERA-6AEB3163V exhibits ±25ppm/°C temperature coefficient, which is higher than the original RG2012N-3163-B-T1 (±10ppm/°C). For applications with strict temperature stability requirements, RG2012N-3163-B-T5 or the upgraded Susumu "-W" series parts are preferred. ERA-6AEB3163V remains acceptable for general automotive applications within AEC-Q200 specifications.

Q: Why would TNPW0805316KBYEA be selected over direct equivalents?

A: TNPW0805316KBYEA provides 0.26W power rating (double the original 0.125W) and extended operating temperature range to 175°C. Selection is appropriate for circuits with higher power dissipation requirements or elevated thermal environments. The part maintains 316 kOhms ±0.1% specification and AEC-Q200 qualification.

Q: Are all substitute parts compatible with the original 0805 footprint?

A: Yes. All substitute parts are specified for 0805 (2012 Metric) package with identical length (0.079") and width (0.049") dimensions. Height variations are minimal (0.50mm to 0.60mm maximum seated height) and do not affect PCB assembly compatibility.

Q: What is the significance of MSL 1 (Unlimited) rating?

A: MSL 1 rating indicates unlimited shelf life without moisture baking requirements. All substitute parts carry this rating, eliminating moisture sensitivity concerns during storage and handling.

Q: Can the obsolete RG2012N-3163-B-T1 be restocked?

A: The RG2012N-3163-B-T1 is marked as obsolete. RG2012N-3163-B-T5 (active product status, 1,051 pcs available) is the direct Susumu replacement. For alternative sources, ERA-6AEB3163V (Panasonic, 24,018 pcs available) provides equivalent specifications with higher inventory availability.
