RN70D1502FRE6 Equivalent & Substitute Parts

Part Overview

The RN70D1502FRE6 is a 15 kOhms ±1% metal film through-hole resistor rated at 0.75W (3/4W) in axial package configuration. Manufactured by Vishay Dale under the military-grade RN70 series (MIL-R-10509/3), this component features flame retardant coating, moisture resistance, and safety-rated construction suitable for military and high-reliability applications. The part maintains active product status with 804 units currently in stock. Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained while addressing packaging, inventory, or supply chain requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RN70D1502FRE6 is determined by the following critical parameters:

• Resistance value: 15 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.75W (exact match required)
• Composition: Metal Film (exact match required)
• Package: Axial through-hole (exact match required)
• Physical dimensions: 0.180" Dia x 0.562" L (exact match required)
• Operating temperature range: -65°C to 175°C (exact match required)
• Series: RN70 military-grade classification (exact match required)

The identified substitute part RN70C1502FB14 maintains all critical electrical and mechanical parameters. The primary difference is packaging format (Bulk versus Tape & Reel) and temperature coefficient specification (±50ppm/°C versus ±100ppm/°C), both of which remain within acceptable substitution criteria for this component category.

Parameter Comparison

Engineering Selection Recommendations

Both RN70D1502FRE6 and RN70C1502FB14 maintain active product status and identical compliance classifications (RoHS non-compliant, REACH Affected). Selection between these parts is determined by packaging requirements and supply chain considerations rather than electrical performance differences.

The RN70D1502FRE6 is specified for automated assembly processes requiring Tape & Reel packaging format. The RN70C1502FB14 is supplied in Bulk packaging, suitable for manual assembly or alternative handling procedures. The temperature coefficient difference (±50ppm/°C versus ±100ppm/°C) represents an improvement in the substitute part and does not restrict substitution eligibility.

Both parts comply with military-grade MIL-R-10509/3 specifications and maintain identical electrical characteristics across the full operating temperature range of -65°C to 175°C.

Frequently Asked Questions (FAQ)

Q: Can RN70C1502FB14 replace RN70D1502FRE6 in existing designs?

A: Yes. Both parts are electrically and mechanically identical. The primary difference is packaging format (Bulk versus Tape & Reel). Substitution is valid provided the assembly process accommodates Bulk packaging.

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

A: The RN70C1502FB14 specifies ±50ppm/°C compared to ±100ppm/°C for the RN70D1502FRE6. This represents improved temperature stability in the substitute part and does not restrict substitution.

Q: Are both parts suitable for military applications?

A: Yes. Both parts are classified under the military-grade RN70 series and comply with MIL-R-10509/3 specifications. Both feature flame retardant coating, moisture resistance, and safety-rated construction.

Q: What packaging considerations apply to substitution?

A: The RN70D1502FRE6 is supplied in Tape & Reel format for automated pick-and-place assembly. The RN70C1502FB14 is supplied in Bulk format, requiring manual handling or alternative assembly procedures. Verify assembly equipment compatibility before substitution.

Q: Do both parts have identical physical dimensions?

A: Yes. Both parts measure 0.180" Dia x 0.562" L (4.57mm x 14.27mm) and are compatible with identical PCB footprints and mounting hardware.

Q: Are there compliance differences between these parts?

A: No. Both parts share identical RoHS and REACH compliance status (RoHS non-compliant, REACH Affected). Both maintain active product status.
