RN65D7503FRE6 Equivalent & Substitute Parts

Part Overview

The RN65D7503FRE6 is a 750 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-rated construction suitable for military and high-reliability applications. The part is currently active in production with 737 units in stock. Substitute parts may be required due to packaging availability, inventory constraints, or specific procurement requirements while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RN65D7503FRE6 is determined by strict equivalence across the following parameters:

• Resistance value: 750 kOhms
• Tolerance: ±1%
• Power rating: 0.5W (1/2W)
• Composition: Metal Film
• Package type: Axial
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -65°C to 175°C
• Physical dimensions: 0.180" Dia x 0.562" L (4.57mm x 14.27mm)
• Series compliance: MIL-R-10509/2, RN65

The primary difference between the main part and its substitute is packaging format: the RN65D7503FRE6 is supplied in Tape & Reel (TR) configuration, while the substitute RN65D7503FB14 is supplied in Bulk packaging. Both parts are manufactured by Vishay Dale and share identical electrical and mechanical characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both the RN65D7503FRE6 and RN65D7503FB14 are active production parts manufactured by Vishay Dale with identical electrical and mechanical specifications. Selection between these parts should be based on packaging requirements and procurement logistics:

• RN65D7503FRE6 (Tape & Reel): Suitable for automated assembly processes and high-volume production environments requiring reel-based component feeding.
• RN65D7503FB14 (Bulk): Suitable for manual assembly, low-volume applications, or procurement scenarios where bulk packaging is preferred.

Both parts maintain compliance with MIL-R-10509/2 military specifications, feature identical RoHS and REACH status, and are suitable for applications requiring military-grade reliability across the -65°C to 175°C operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can RN65D7503FB14 be used as a direct replacement for RN65D7503FRE6?

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

Q: What is the significance of the packaging difference between these parts?

A: Tape & Reel (TR) packaging is optimized for automated pick-and-place assembly systems, while Bulk packaging is typically used for manual assembly or component kitting. The electrical performance and physical dimensions are identical.

Q: Are both parts compliant with military specifications?

A: Yes. Both RN65D7503FRE6 and RN65D7503FB14 comply with MIL-R-10509/2 military specifications and are part of the RN65 series.

Q: What is the operating temperature range for these resistors?

A: Both parts operate across -65°C to 175°C with a temperature coefficient of ±100ppm/°C.

Q: Are these parts RoHS compliant?

A: No. Both parts are RoHS non-compliant but are REACH Affected. Verify compliance requirements for your specific application.
