RN55D8872FRE6 Equivalent & Substitute Parts

Part Overview

The RN55D8872FRE6 is an 88.7 kOhms ±1% metal film through-hole resistor rated at 0.125W (1/8W) in axial package configuration. Manufactured by Vishay Dale, this component is part of the military-grade RN55 series compliant with MIL-R-10509/7 specifications. The part features flame retardant coating, moisture resistance, and safety-rated construction suitable for military and high-reliability applications. Finding equivalent substitute parts becomes necessary when the tape and reel (TR) packaging is unavailable or when bulk packaging alternatives are required for procurement flexibility while maintaining identical electrical and mechanical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RN55D8872FRE6 is determined by strict equivalence across the following critical parameters:

• Resistance value: 88.7 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.125W / 1/8W (exact match required)
• Composition: Metal Film (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -65°C to 175°C (exact match required)
• Package configuration: Axial through-hole (exact match required)
• Physical dimensions: 0.090" Dia x 0.240" L (exact match required)
• Series compliance: MIL-R-10509/7, RN55 (exact match required)

The primary difference between the main part and its substitute is packaging format: tape and reel (TR) versus bulk. This distinction affects procurement and handling but does not alter electrical or mechanical performance.

Parameter Comparison

Engineering Selection Recommendations

Both RN55D8872FRE6 and RN55D8872FB14 are active products from Vishay Dale with identical electrical specifications and military-grade construction. Selection between these parts should be based on procurement requirements and assembly processes:

The RN55D8872FRE6 in tape and reel packaging is suitable for automated pick-and-place assembly operations and high-volume production environments where component feeding systems require standardized reel formats.

The RN55D8872FB14 in bulk packaging is appropriate for manual assembly, low-volume production, repair operations, or applications where tape and reel infrastructure is not available. Both parts maintain RoHS non-compliant status and REACH affected classification, consistent with military-grade specifications.

Frequently Asked Questions (FAQ)

Q: Can RN55D8872FB14 (bulk) be used as a direct replacement for RN55D8872FRE6 (tape and reel)?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format. Bulk packaging does not affect component performance, electrical characteristics, or reliability in the application circuit.

Q: Are there any compatibility issues when substituting between tape and reel and bulk packaging?

A: No compatibility issues exist at the component level. The substitution affects only procurement, storage, and assembly handling procedures. Circuit performance remains unchanged.

Q: Do both parts meet the same military specifications?

A: Yes. Both RN55D8872FRE6 and RN55D8872FB14 comply with MIL-R-10509/7 specifications and are part of the RN55 military-grade resistor series.

Q: What is the significance of the ±1% tolerance specification?

A: The ±1% tolerance indicates that the actual resistance value will fall within 87.822 kOhms to 89.578 kOhms. This tight tolerance is critical for precision circuit applications and is maintained identically across both substitute parts.

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

A: No. Both parts share identical RoHS non-compliant status, REACH affected classification, and operating temperature range of -65°C to 175°C. Environmental performance and compliance posture are equivalent.
