Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RN55E2210FRE6 is determined by the following critical parameters:

• Resistance Value: Must be 221 Ohms
• Power Rating: Must be 0.125W (1/8W)
• Composition: Must be Metal Film
• Package Type: Must be Axial
• Physical Dimensions: Must be 0.090" Dia × 0.240" L
• Operating Temperature Range: Must be -65°C to 175°C
• Temperature Coefficient: Must be ±25ppm/°C
• Series Compliance: Must conform to MIL-R-10509/7 and RN55 series

The identified substitute part RN55E2210BB14 meets all critical electrical and mechanical parameters. The primary difference is packaging format (Bulk versus Tape & Reel) and tolerance specification (±0.1% versus ±1%), representing an upgrade in tolerance capability while maintaining all other functional requirements.

Parameter Comparison

Engineering Selection Recommendations

Both RN55E2210FRE6 and RN55E2210BB14 are active products from Vishay Dale with identical military-grade specifications and compliance status. Selection between these parts should be based on:

Packaging Requirements: The RN55E2210FRE6 is supplied in Tape & Reel format, suitable for automated assembly processes. The RN55E2210BB14 is supplied in Bulk format, appropriate for manual assembly or alternative handling methods.

Tolerance Specification: The RN55E2210BB14 provides ±0.1% tolerance compared to the ±1% tolerance of the RN55E2210FRE6. Applications requiring tighter tolerance control may benefit from the substitute part.

Compliance Considerations: Both parts maintain identical RoHS non-compliant and REACH Affected status, ensuring consistent regulatory treatment in procurement and assembly workflows.

Frequently Asked Questions (FAQ)

Q: Can RN55E2210BB14 be used as a direct replacement for RN55E2210FRE6?

A: Yes. Both parts share identical electrical specifications (221 Ohms, ±25ppm/°C, -65°C to 175°C operating range), mechanical dimensions (0.090" Dia × 0.240" L), and military-grade construction. The substitute part offers improved tolerance (±0.1% versus ±1%) and differs only in packaging format (Bulk versus Tape & Reel).

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

A: Tape & Reel packaging is designed for automated pick-and-place assembly equipment, with components wound on continuous tape. Bulk packaging consists of loose components suitable for manual assembly or alternative handling systems. Both formats contain identical components.

Q: Does the tighter tolerance of RN55E2210BB14 affect circuit performance?

A: The ±0.1% tolerance of RN55E2210BB14 is a subset of the ±1% tolerance specification of RN55E2210FRE6. Applications designed for ±1% tolerance will function identically with the tighter tolerance substitute. Applications requiring specific tolerance bands should verify compatibility with design specifications.

Q: Are both parts suitable for military applications?

A: Yes. Both RN55E2210FRE6 and RN55E2210BB14 conform to MIL-R-10509/7 specifications and are designated as military-grade components with flame retardant coating, moisture resistance, and safety-rated construction.

Q: What is the inventory status for these parts?

A: RN55E2210FRE6 has 1072 units in stock. RN55E2210BB14 has 1071 units in stock. Both parts maintain active product status with Vishay Dale.
