RN65D1502FRE6 Equivalent & Substitute Parts

Part Overview

The RN65D1502FRE6 is a 15 kOhms ±1% metal film through-hole resistor rated at 0.5W (1/2W) in axial package configuration. Manufactured by Vishay Dale under the military-grade RN65 series (MIL-R-10509/2), this component features flame retardant coating, moisture resistance, and safety certification suitable for military and high-reliability applications. The part is currently active in production with 826 units in stock. Substitute parts may be required due to inventory constraints, application-specific power rating requirements, or design optimization needs.

Substitute Part Grouping Explanation

The RN65D1502FRE6 can be substituted with the RN70C1502FB14 based on the following allowable parameter variations:

Matching Parameters (Substitution Basis):

• Resistance value: 15 kOhms (identical)
• Tolerance: ±1% (identical)
• Composition: Metal Film (identical)
• Package type: Axial (identical)
• Operating temperature range: -65°C to 175°C (identical)
• Features: Flame Retardant Coating, Moisture Resistant, Safety (identical)
• Military classification: MIL-R-10509 series (both compliant)

Differing Parameters (Upgrade Characteristics):

• Power rating: 0.75W (3/4W) versus 0.5W (1/2W) — higher power capacity
• Temperature coefficient: ±50ppm/°C versus ±100ppm/°C — improved stability
• Packaging format: Bulk versus Tape & Reel
• Base series: RN70 versus RN65

The RN70C1502FB14 represents an upgrade path with enhanced thermal performance and power handling capability while maintaining electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the RN65D1502FRE6 and RN70C1502FB14 maintain active production status and identical regulatory compliance profiles (RoHS non-compliant, REACH Affected, ECCN EAR99). Selection between these parts should be based on application power dissipation requirements:

• RN65D1502FRE6: Select for applications with power dissipation at or below 0.5W and where the standard temperature coefficient of ±100ppm/°C is acceptable.
• RN70C1502FB14: Select for applications requiring power dissipation between 0.5W and 0.75W, or where improved temperature stability (±50ppm/°C) is specified.

Both parts are mechanically and electrically interchangeable in axial through-hole circuit board layouts. The identical physical dimensions (0.180" Dia x 0.562" L) ensure direct board-level substitution without layout modification.

Frequently Asked Questions (FAQ)

Q: Can RN70C1502FB14 directly replace RN65D1502FRE6 in existing designs?

A: Yes. Both parts share identical resistance (15 kOhms), tolerance (±1%), axial package configuration, and physical dimensions. The RN70C1502FB14 provides higher power rating (0.75W versus 0.5W) and improved temperature coefficient (±50ppm/°C versus ±100ppm/°C), making it a direct upgrade-compatible substitute.

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

A: The RN70C1502FB14 offers enhanced power handling capacity (0.75W versus 0.5W) and superior temperature stability (±50ppm/°C versus ±100ppm/°C). Both parts belong to the Vishay Dale military RN series and maintain identical electrical specifications for resistance and tolerance.

Q: Are there packaging differences between these parts?

A: Yes. The RN65D1502FRE6 is supplied in Tape & Reel (TR) packaging, while the RN70C1502FB14 is supplied in Bulk packaging. This affects procurement and handling but does not impact electrical or mechanical performance in the application.

Q: Do both parts meet the same military specifications?

A: Both parts comply with MIL-R-10509 military resistor specifications. The RN65D1502FRE6 follows MIL-R-10509/2, while the RN70C1502FB14 follows MIL-R-10509/3. Both maintain flame retardant coating, moisture resistance, and safety features required for military-grade applications.

Q: What is the temperature coefficient significance in selecting between these parts?

A: Temperature coefficient indicates resistance value drift with temperature change. The RN70C1502FB14 (±50ppm/°C) exhibits half the drift rate of the RN65D1502FRE6 (±100ppm/°C). For precision analog circuits or wide temperature range applications, the lower temperature coefficient of the RN70C1502FB14 provides improved stability.
