Substitute Part Grouping Explanation

Substitution eligibility for the RN70D1503FRE6 is determined by the following critical parameters:

• Resistance value: 150 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: Axial through-hole (exact match required)
• Operating temperature range: -65°C to 175°C (exact match required)
• Series compliance: RN70 military series per MIL-R-10509/3 (exact match required)

The RN70C1503FB14 qualifies as a direct substitute based on identical electrical specifications and mechanical dimensions. The primary distinction is packaging format: RN70D1503FRE6 is supplied in Tape & Reel (TR) configuration, while RN70C1503FB14 is supplied in Bulk packaging. Both components share the same base product number (RN70) and maintain full compatibility in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both RN70D1503FRE6 and RN70C1503FB14 maintain active product status and are manufactured to identical military specifications. Selection between these parts is determined by supply chain and assembly requirements rather than electrical performance.

The RN70D1503FRE6 in Tape & Reel packaging is suitable for automated assembly processes requiring component feeding from tape reels. The RN70C1503FB14 in Bulk packaging is appropriate for manual assembly operations or when tape reel packaging is not required.

Both components share identical RoHS non-compliant and REACH Affected compliance status. The RN70C1503FB14 exhibits a superior temperature coefficient of ±50ppm/°C compared to the RN70D1503FRE6 at ±100ppm/°C, providing enhanced temperature stability in applications with strict thermal performance requirements.

Frequently Asked Questions (FAQ)

Q: Can RN70C1503FB14 replace RN70D1503FRE6 in existing designs?

A: Yes. Both components are electrically and mechanically identical with matching resistance, tolerance, power rating, temperature range, and physical dimensions. The only difference is packaging format (Bulk versus Tape & Reel).

Q: What is the primary difference between these two parts?

A: The RN70D1503FRE6 is supplied in Tape & Reel format for automated pick-and-place assembly, while RN70C1503FB14 is supplied in Bulk format. Electrical specifications and physical dimensions are identical.

Q: Does the temperature coefficient difference affect substitution compatibility?

A: The RN70C1503FB14 temperature coefficient of ±50ppm/°C is superior to the RN70D1503FRE6 at ±100ppm/°C. This represents an improvement in thermal stability and does not prevent substitution. Applications requiring the lower temperature coefficient benefit from using RN70C1503FB14.

Q: Are both parts compliant with military specifications?

A: Both components comply with MIL-R-10509/3 military specification and are part of the RN70 military-grade series. Both maintain RoHS non-compliant and REACH Affected status.

Q: What inventory considerations apply to these substitutes?

A: RN70D1503FRE6 has 1175 units in stock, while RN70C1503FB14 has 843 units in stock. Selection may depend on required delivery quantities and assembly process capabilities.
