RN70C1502FRSL Equivalent & Substitute Parts

Part Overview

The RN70C1502FRSL 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 is currently active in production with 709 units in stock. Substitute parts may be required due to packaging availability, inventory constraints, or specific procurement requirements while maintaining identical electrical and mechanical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RN70C1502FRSL is determined by strict equivalence across the following critical parameters:

Resistance value must be exactly 15 kOhms with ±1% tolerance. Power rating must be 0.75W (3/4W). Composition must be metal film. Package configuration must be axial with identical physical dimensions (0.180" Dia × 0.562" L). Temperature coefficient must be ±50ppm/°C. Operating temperature range must span -65°C to 175°C. Series classification must remain within the military RN70 family (MIL-R-10509/3). All substitute parts must retain flame retardant coating, military qualification, moisture resistance, and safety features.

The primary difference between the main part and its substitute is packaging format: the main part RN70C1502FRSL is supplied in Tape & Reel (TR) configuration, while the substitute RN70C1502FB14 is supplied in Bulk packaging. Both parts are identical in electrical performance, physical dimensions, and functional characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both RN70C1502FRSL and RN70C1502FB14 are active production components manufactured by Vishay Dale. Selection between these parts should be based on packaging requirements and inventory availability. The RN70C1502FRSL in Tape & Reel format is suitable for automated assembly processes and high-volume production runs. The RN70C1502FB14 in Bulk packaging is appropriate for manual assembly, prototype development, or applications where tape-and-reel handling is not required. Both parts carry identical RoHS non-compliant status, REACH Affected designation, EAR99 ECCN classification, and HTSUS code 8533.21.0090. Selection of either part does not introduce compliance or certification differences.

Frequently Asked Questions (FAQ)

Q: Can RN70C1502FB14 be used as a direct replacement for RN70C1502FRSL in production assembly?

A: Yes, provided the assembly process can accommodate bulk packaging. The electrical and mechanical specifications are identical. Automated pick-and-place equipment typically requires Tape & Reel format, while manual assembly can use either format.

Q: Are there any electrical performance differences between these two parts?

A: No. Both parts have identical resistance value (15 kOhms), tolerance (±1%), power rating (0.75W), temperature coefficient (±50ppm/°C), and operating temperature range (-65°C to 175°C).

Q: What is the significance of the packaging difference between TR and Bulk formats?

A: Tape & Reel (TR) packaging is designed for automated assembly equipment and provides organized component feeding. Bulk packaging contains loose components suitable for manual assembly or lower-volume applications. The physical component itself is unchanged.

Q: Do both parts meet military specifications?

A: Yes. Both RN70C1502FRSL and RN70C1502FB14 are classified as military-grade components within the RN70 series and comply with MIL-R-10509/3 specifications.

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

A: Both parts have identical axial package dimensions of 0.180" diameter × 0.562" length (4.57mm × 14.27mm). They are mechanically interchangeable on PCBs designed for axial through-hole resistors.

Q: Are there inventory considerations for selecting between these parts?

A: Current inventory shows 1179 units of RN70C1502FB14 (Bulk) versus 709 units of RN70C1502FRSL (Tape & Reel). Bulk format availability is higher, which may influence procurement decisions based on lead time requirements.
