Substitute Part Grouping Explanation

Substitution eligibility for the RN55C1304FRE6 is determined by strict equivalence across the following critical parameters:

• Resistance value: 1.3 MOhms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Composition: Metal Film
• Temperature coefficient: ±50ppm/°C
• Operating temperature range: -65°C to 175°C
• Package type: Axial
• Physical dimensions: 0.090" Dia × 0.240" L (2.29mm × 6.10mm)
• Series: Military, MIL-R-10509/7, RN55
• Features: Flame Retardant Coating, Military, Moisture Resistant, Safety

The RN55C1304FB14 qualifies as a direct substitute based on identical electrical and mechanical parameters. The distinction between these parts is packaging format: the main part (RN55C1304FRE6) is supplied in Tape & Reel (TR) configuration, while the substitute (RN55C1304FB14) is supplied in Bulk packaging. Both parts share the same base product number (RN55) and maintain equivalent performance characteristics across all specified operating conditions.

Parameter Comparison

Engineering Selection Recommendations

Both the RN55C1304FRE6 and RN55C1304FB14 maintain active product status from Vishay Dale and are suitable for applications requiring military-grade resistors with MIL-R-10509/7 compliance. Selection between these parts should be based on procurement and assembly requirements:

The RN55C1304FRE6 in Tape & Reel packaging is appropriate for automated assembly processes and high-volume production environments where component feeding systems require standardized reel formats.

The RN55C1304FB14 in Bulk packaging is appropriate for manual assembly, low-volume production, or applications where reel-based component handling is not required.

Both parts carry identical RoHS non-compliant status and REACH Affected classification. Compliance requirements for specific applications must be evaluated independently of the packaging format distinction.

Frequently Asked Questions (FAQ)

Q: Can RN55C1304FB14 be used as a direct replacement for RN55C1304FRE6?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format: Tape & Reel versus Bulk. Substitution is valid for any application where the component specifications are met, provided assembly processes can accommodate the different packaging format.

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

A: Tape & Reel (TR) packaging supplies components wound on a continuous tape and reel, designed for automated pick-and-place assembly equipment. Bulk packaging supplies loose components in quantities suitable for manual handling or alternative assembly methods. Electrical and mechanical performance are identical.

Q: Are there any performance differences between these substitute parts?

A: No. Both parts share identical resistance value (1.3 MOhms), tolerance (±1%), power rating (0.125W), temperature coefficient (±50ppm/°C), operating temperature range (-65°C to 175°C), and physical dimensions (0.090" Dia × 0.240" L). Performance in circuit applications is equivalent.

Q: Do both parts meet military specifications?

A: Yes. Both RN55C1304FRE6 and RN55C1304FB14 are classified as military-grade components within the RN55 series and comply with MIL-R-10509/7 specifications. Military classification, flame retardant coating, and moisture resistance features are identical across both parts.

Q: What should determine my choice between these two parts?

A: Selection should be based on your assembly process requirements and packaging handling capabilities. If your production line uses automated component feeders, Tape & Reel format is appropriate. If your assembly process is manual or uses alternative feeding systems, Bulk packaging may be more suitable. Both parts deliver identical electrical performance.
