RN55D9531FRE6 Equivalent & Substitute Parts

Part Overview

The RN55D9531FRE6 is a 9.53 kOhms ±1% metal film through-hole resistor rated at 0.125W (1/8W) in axial package configuration. Manufactured by Vishay Dale under the military-grade RN55 series per MIL-R-10509/7 specification, 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 809 units in stock. Substitute parts are identified to provide alternative sourcing options when the primary packaging format (Tape & Reel) is unavailable or when bulk quantities are required.

Substitute Part Grouping Explanation

Substitution eligibility for the RN55D9531FRE6 is determined by strict equivalence across the following electrical and mechanical parameters:

• Resistance value: 9.53 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.125W / 1/8W (exact match required)
• Composition: Metal Film (exact match required)
• Package configuration: Axial through-hole (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -65°C to 175°C (exact match required)
• Series compliance: Military, MIL-R-10509/7, RN55 (exact match required)
• Physical dimensions: 0.090" Dia × 0.240" L (exact match required)

The identified substitute part differs only in packaging format (Bulk versus Tape & Reel), which does not affect electrical performance or mechanical compatibility in the application circuit.

Parameter Comparison

Engineering Selection Recommendations

Both the RN55D9531FRE6 and RN55D9531FB14 are active production parts manufactured by Vishay Dale with identical electrical specifications and military-grade certifications. Selection between these parts is determined by packaging and inventory requirements rather than technical performance.

The RN55D9531FRE6 in Tape & Reel format is suitable for automated assembly processes and high-volume production runs. The RN55D9531FB14 in Bulk packaging is appropriate for manual assembly, prototype development, or applications where reel handling equipment is unavailable. Both parts maintain equivalent compliance status under RoHS non-compliant and REACH Affected classifications with EAR99 export control designation.

Frequently Asked Questions (FAQ)

Q: Can RN55D9531FB14 be used as a direct replacement for RN55D9531FRE6?

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 equivalent.

Q: What is the difference between Tape & Reel and Bulk packaging?

A: Tape & Reel (TR) packaging is designed for automated pick-and-place assembly equipment and is standard for high-volume manufacturing. Bulk packaging contains loose components suitable for manual assembly or lower-volume applications. Both formats contain the same component.

Q: Are there any compliance differences between these parts?

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

Q: Which part should be selected for military applications?

A: Both parts meet military specifications under the MIL-R-10509/7 standard and RN55 series designation. Selection depends on assembly process requirements: use RN55D9531FRE6 for automated assembly or RN55D9531FB14 for manual assembly.

Q: Is inventory availability a factor in part selection?

A: Inventory levels may influence sourcing decisions. RN55D9531FB14 currently has higher stock availability (2143 units) compared to RN55D9531FRE6 (809 units). However, both parts are active production items.
