Key Parameters

Substitute Part Grouping Explanation

Substitute parts for RN60D1201FRE6 are classified based on the following allowed parameters:

Electrical Parameters (Must Match):

• Resistance value: 1.2 kOhms
• Power rating: 0.25W (1/4W)
• Composition: Metal Film
• Operating temperature range: -65°C to 175°C
• Series: RN60 (Military, MIL-R-10509/1)

Tolerance & Temperature Coefficient (Upgrade Criteria):

• Tolerance may be tighter (±0.5% or ±0.1%) than the original ±1%
• Temperature coefficient may be lower (±50ppm/°C) than the original ±100ppm/°C

Mechanical Parameters (Must Match):

• Package type: Axial
• Physical dimensions: 0.145" Dia x 0.344" L (3.68mm x 8.74mm)
• Number of terminations: 2

Packaging Format (Variable):

• Original part: Cut Tape (CT)
• Substitutes available in: Bulk

All substitute parts maintain identical electrical performance, mechanical compatibility, and military-grade specifications while offering alternative packaging formats and enhanced tolerance/temperature coefficient characteristics.

Parameter Comparison

Engineering Selection Recommendations

RN60D1201FB14 (Direct Substitute): This part provides direct electrical equivalence to RN60D1201FRE6 with identical tolerance (±1%) and temperature coefficient (±100ppm/°C). The only difference is packaging format (Bulk vs. Cut Tape). Selection is appropriate when bulk packaging meets assembly requirements and higher inventory availability (4885 units) is advantageous.

RN60C1201DB14 (Upgrade Substitute): This part offers improved tolerance (±0.5%) and reduced temperature coefficient (±50ppm/°C) compared to the main part. All other electrical and mechanical parameters remain equivalent. Selection is appropriate for applications requiring tighter tolerance control and enhanced temperature stability. Lower inventory (1011 units) should be considered in procurement planning.

RN60C1201BB14 (Upgrade Substitute): This part provides the highest tolerance specification (±0.1%) and lowest temperature coefficient (±50ppm/°C) among all options. Electrical and mechanical compatibility is maintained. Selection is appropriate for precision applications requiring maximum tolerance and temperature coefficient performance. Inventory availability is 2179 units.

All substitute parts maintain RoHS non-compliant status, REACH affected classification, and military-grade specifications identical to the main part.

Frequently Asked Questions (FAQ)

Q: Can RN60D1201FB14 be used as a direct replacement for RN60D1201FRE6?

A: Yes. RN60D1201FB14 is electrically and mechanically equivalent with identical resistance (1.2 kOhms), tolerance (±1%), power rating (0.25W), temperature coefficient (±100ppm/°C), and physical dimensions. The difference is packaging format: RN60D1201FRE6 is supplied in Cut Tape, while RN60D1201FB14 is supplied in Bulk. Compatibility depends on assembly equipment capability to handle bulk packaging.

Q: What is the difference between the upgrade parts RN60C1201DB14 and RN60C1201BB14?

A: Both upgrade parts offer improved specifications compared to the main part. RN60C1201DB14 provides ±0.5% tolerance with ±50ppm/°C temperature coefficient. RN60C1201BB14 provides tighter ±0.1% tolerance with ±50ppm/°C temperature coefficient. All other parameters including resistance value, power rating, operating temperature range, and physical dimensions are identical. Selection between these upgrades depends on tolerance precision requirements.

Q: Are all substitute parts compatible with the same PCB footprint?

A: Yes. All substitute parts maintain identical axial package configuration with dimensions of 0.145" Dia x 0.344" L (3.68mm x 8.74mm). PCB footprint and lead spacing are compatible across all parts listed.

Q: What is the significance of the temperature coefficient difference?

A: Temperature coefficient indicates resistance value change per degree Celsius. The main part and RN60D1201FB14 have ±100ppm/°C, while upgrade parts RN60C1201DB14 and RN60C1201BB14 have ±50ppm/°C. Lower temperature coefficient means more stable resistance across the operating temperature range (-65°C to 175°C). Selection depends on circuit sensitivity to resistance variation over temperature.

Q: Can these parts be used interchangeably in military applications?

A: All parts are manufactured under the RN60 military series (MIL-R-10509/1) with identical military-grade specifications including flame retardant coating, moisture resistance, and safety features. Interchangeability in military applications is determined by specific circuit tolerance and temperature coefficient requirements, not by military classification alone.
