Substitute Part Grouping Explanation

Substitution eligibility for the RN70D1004FRE6 is determined by the following critical parameters:

• Resistance value: 1 MOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.75W (exact match required)
• Composition: Metal Film (exact match required)
• Package type: Axial (exact match required)
• Operating temperature range: -65°C to 175°C (exact match required)
• Physical dimensions: 0.180" Dia x 0.562" L (exact match required)
• Series compliance: Military, MIL-R-10509/3, RN70 (exact match required)

The identified substitute parts RN70D1004FB14 and RN70C1004FB14 meet all critical electrical and mechanical parameters. The primary difference between these parts is packaging format (Cut Tape versus Bulk) and, in the case of RN70C1004FB14, a superior temperature coefficient specification (±50ppm/°C versus ±100ppm/°C).

Parameter Comparison

Engineering Selection Recommendations

RN70D1004FB14 serves as a direct functional equivalent to RN70D1004FRE6. Both parts share identical electrical specifications and physical dimensions. The substitution is valid when bulk packaging is acceptable for assembly operations. All three parts maintain active production status and comply with military specifications MIL-R-10509/3.

RN70C1004FB14 represents an upgraded alternative with improved temperature coefficient performance (±50ppm/°C versus ±100ppm/°C). This part is suitable for applications requiring enhanced temperature stability while maintaining all other electrical and mechanical compatibility. The RN70C variant is part of the same military RN70 series and meets identical dimensional and power requirements.

Selection between these parts should be based on packaging requirements (Cut Tape versus Bulk) and temperature stability needs. All three parts are RoHS non-compliant and REACH-affected, with identical compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can RN70D1004FB14 replace RN70D1004FRE6 in production assembly?

A: Yes. RN70D1004FB14 is electrically and mechanically identical to RN70D1004FRE6. The only difference is packaging format (Bulk versus Cut Tape). Compatibility depends on assembly equipment capability to handle bulk packaging.

Q: What is the difference between RN70D1004FB14 and RN70C1004FB14?

A: Both parts are functionally equivalent with identical resistance, tolerance, power rating, and dimensions. RN70C1004FB14 features a superior temperature coefficient of ±50ppm/°C compared to ±100ppm/°C in RN70D1004FB14. This provides better resistance stability across the operating temperature range.

Q: Are all three parts suitable for military applications?

A: Yes. All three parts comply with military specification MIL-R-10509/3 and belong to the military-grade RN70 series. They feature flame retardant coating, moisture resistance, and safety certification.

Q: What packaging formats are available?

A: RN70D1004FRE6 is supplied in Cut Tape (CT) format. RN70D1004FB14 and RN70C1004FB14 are supplied in Bulk packaging. Select based on assembly line requirements.

Q: Can these parts be used interchangeably in high-temperature applications?

A: All three parts operate across -65°C to 175°C. For applications requiring maximum temperature stability, RN70C1004FB14 with ±50ppm/°C temperature coefficient is preferred over the ±100ppm/°C variants.
