RN60D1581FRE6 Equivalent & Substitute Parts

Part Overview

The RN60D1581FRE6 is a 1.58 kOhms ±1% metal film through-hole resistor rated at 0.25W (1/4W) in axial package configuration. Manufactured by Vishay Dale under the military-grade RN60 series (MIL-R-10509/1), 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 850 pieces available in tape & reel packaging. Substitute parts may be required due to packaging format availability, inventory constraints, or specific procurement requirements while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RN60D1581FRE6 is determined by strict equivalence across the following critical parameters:

• Resistance value: 1.58 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.25W / 1/4W (exact match required)
• Composition: Metal Film (exact match required)
• Package configuration: Axial (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -65°C to 175°C (exact match required)
• Series designation: RN60 / MIL-R-10509/1 (exact match required)
• Physical dimensions: 0.145" Dia × 0.344" L (exact match required)

The primary variable among qualified substitutes is packaging format (tape & reel versus bulk), which does not affect electrical or mechanical performance. All substitute parts must maintain identical electrical characteristics, construction materials, protective coatings, and military-grade specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the RN60D1581FRE6 and RN60D1581FB14 are electrically and mechanically identical components from the same manufacturer and series. The sole distinction is packaging format: tape & reel versus bulk. Selection between these parts should be based on procurement and assembly requirements rather than technical performance criteria.

Both parts maintain active product status and identical compliance profiles (RoHS non-compliant, REACH Affected, ECCN EAR99, HTSUS 8533.21.0090). Military-grade construction, flame retardant coating, and moisture resistance specifications are equivalent across both variants.

Frequently Asked Questions (FAQ)

Q: Can RN60D1581FB14 be used as a direct replacement for RN60D1581FRE6?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (bulk versus tape & reel). Electrical performance, tolerance, power rating, temperature characteristics, and physical dimensions are identical.

Q: What is the difference between tape & reel and bulk packaging?

A: Tape & reel (TR) packaging is used for automated assembly processes and provides components wound on continuous tape. Bulk packaging supplies loose components. This distinction affects handling and assembly methodology but does not impact component performance or specifications.

Q: Are the military specifications identical between both parts?

A: Yes. Both parts conform to MIL-R-10509/1 specifications and carry identical military-grade designations, flame retardant coatings, and moisture resistance ratings.

Q: Do both parts have the same operating temperature range?

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

Q: Are there any compliance differences between the two parts?

A: No. Both parts share identical RoHS status (non-compliant), REACH status (Affected), ECCN classification (EAR99), and HTSUS code (8533.21.0090).
