Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RN70D1501FRE6 is determined by the following critical parameters:

• Resistance value: 1.5 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.75W / 3/4W (exact match required)
• Composition: Metal Film (exact match required)
• Package type: Axial (exact match required)
• Physical dimensions: 0.180" Dia x 0.562" L (exact match required)
• Operating temperature range: -65°C ~ 175°C (exact match required)
• Series compliance: MIL-R-10509/3, RN70 (exact match required)

The identified substitute parts RN70D1501FB14 and RN70C1501FB14 satisfy all mandatory electrical and mechanical parameters. Variations in packaging format (Tape & Reel versus Bulk) and temperature coefficient performance do not affect functional interchangeability in applications where the core electrical specifications are the controlling requirement.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active production status and identical compliance posture with respect to RoHS and REACH regulations. Selection between RN70D1501FRE6, RN70D1501FB14, and RN70C1501FB14 is determined by packaging requirements and temperature stability performance criteria.

RN70D1501FRE6 is supplied in Tape & Reel format, suitable for automated assembly processes. RN70D1501FB14 and RN70C1501FB14 are supplied in Bulk packaging, appropriate for manual assembly or alternative handling workflows.

RN70C1501FB14 provides improved temperature coefficient performance at ±50ppm/°C compared to ±100ppm/°C for both RN70D1501FRE6 and RN70D1501FB14. This enhanced stability may be beneficial in applications with stringent temperature drift requirements across the full -65°C to 175°C operating range.

Frequently Asked Questions (FAQ)

Q: Can RN70D1501FB14 directly replace RN70D1501FRE6 in existing designs?

A: Yes. Both parts are electrically and mechanically identical. The difference is packaging format: RN70D1501FRE6 is supplied in Tape & Reel, while RN70D1501FB14 is supplied in Bulk. Functional performance in the circuit is equivalent.

Q: What is the advantage of RN70C1501FB14 over the other two options?

A: RN70C1501FB14 features a temperature coefficient of ±50ppm/°C, compared to ±100ppm/°C for both RN70D1501FRE6 and RN70D1501FB14. This provides superior resistance stability across temperature variations, beneficial for precision applications operating across the full -65°C to 175°C range.

Q: Are all three parts MIL-R-10509/3 compliant?

A: Yes. All three parts conform to MIL-R-10509/3 military specification and are part of the RN70 series.

Q: What is the physical footprint compatibility between these parts?

A: All three parts share identical axial package dimensions of 0.180" diameter by 0.562" length (4.57mm x 14.27mm). PCB layout and mechanical mounting are fully compatible.

Q: Do packaging format differences affect electrical performance?

A: No. Tape & Reel and Bulk packaging formats do not alter electrical characteristics. The difference is in supply and handling method only.

Q: Are there RoHS-compliant alternatives available?

A: The provided data indicates all three parts are RoHS non-compliant. No RoHS-compliant alternatives are listed in the substitute parts database.
