RN55D9761FRE6 Equivalent & Substitute Parts

Part Overview

The RN55D9761FRE6 is a 9.76 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 1100 units in stock. Identifying equivalent substitute parts becomes necessary when the tape and reel packaging format is unavailable or when bulk packaging alternatives are required for procurement optimization.

Substitute Part Grouping Explanation

Substitution eligibility for the RN55D9761FRE6 is determined by strict equivalence across the following critical parameters:

• Resistance value: 9.76 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 classification: RN55 military-grade per MIL-R-10509/7 (exact match required)

The primary distinction between the main part and its substitute lies in packaging format: the RN55D9761FRE6 is supplied in tape and reel (TR) configuration, while the substitute RN55D9761FB14 is supplied in bulk packaging. All electrical, mechanical, and environmental specifications remain identical.

Parameter Comparison

Engineering Selection Recommendations

Both the RN55D9761FRE6 and RN55D9761FB14 maintain identical active product status and are manufactured to the same military-grade specifications under the RN55 series per MIL-R-10509/7. Both parts carry identical RoHS non-compliant and REACH Affected designations, ensuring consistent regulatory treatment across applications.

Selection between these parts should be based solely on packaging requirements: tape and reel format for automated assembly processes, or bulk packaging for manual assembly or alternative procurement workflows. The electrical and environmental performance characteristics are functionally equivalent, with no performance differentiation between the two part numbers.

Frequently Asked Questions (FAQ)

Q: Can RN55D9761FB14 be used as a direct replacement for RN55D9761FRE6?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format: RN55D9761FRE6 is supplied in tape and reel, while RN55D9761FB14 is supplied in bulk. Component performance, reliability, and specifications are equivalent.

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

A: Tape and reel packaging is optimized for automated pick-and-place assembly equipment. Bulk packaging is suitable for manual assembly, kit assembly, or alternative procurement scenarios. The component itself is unchanged.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts carry identical RoHS non-compliant and REACH Affected designations. Both are manufactured to MIL-R-10509/7 military specifications and feature the same flame retardant coating, moisture resistance, and safety-rated construction.

Q: What parameters must remain identical for substitution to be valid?

A: Resistance value (9.76 kOhms), tolerance (±1%), power rating (0.125W), composition (metal film), axial package configuration, temperature coefficient (±100ppm/°C), operating temperature range (-65°C to 175°C), and RN55 series classification must all match exactly.

Q: Is inventory availability a factor in substitution eligibility?

A: No. Inventory levels do not affect electrical or mechanical substitution eligibility. Both parts are active in production. Substitution decisions should be based on packaging format requirements and procurement availability.
