RNC55H6191FPRSL Equivalent & Substitute Parts

Part Overview

The RNC55H6191FPRSL is a 6.19 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 RNC55 series per MIL-PRF-55182/01 specification, this component is designed for applications requiring moisture resistance and weldability in military and high-reliability environments. The part is currently active in production with 907 units in stock. Substitute parts may be required due to packaging availability, inventory constraints, or specific procurement requirements while maintaining identical electrical and mechanical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RNC55H6191FPRSL is determined by strict equivalence across the following critical parameters:

• Resistance value: 6.19 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: ±50ppm/°C (exact match required)
• Operating temperature range: -65°C to 175°C (exact match required)
• Package configuration: Axial (exact match required)
• Physical dimensions: 0.094" Dia x 0.250" L / 2.39mm x 6.35mm (exact match required)
• Military series compliance: MIL-PRF-55182/01, RNC55 (exact match required)

The primary difference between the main part and its substitute lies in packaging format (Tape & Reel versus Bulk) and failure rate classification, which do not affect electrical or mechanical interchangeability in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both RNC55H6191FPRSL and RNC55H6191FSB14 are active production components manufactured by Vishay Dale with identical electrical specifications and military-grade compliance to MIL-PRF-55182/01. Selection between these parts should be based on procurement requirements:

The RNC55H6191FPRSL in Tape & Reel packaging is suitable for automated assembly processes and high-volume production environments. The RNC55H6191FSB14 in Bulk packaging offers a lower failure rate classification (S: 0.001% versus P: 0.1%) and may be preferred for applications with extended operational life requirements or higher reliability mandates. Both parts maintain RoHS non-compliant status and are subject to REACH regulations. Component selection should align with specific assembly methodology, inventory management practices, and reliability specifications of the end application.

Frequently Asked Questions (FAQ)

Q: Can RNC55H6191FSB14 be used as a direct replacement for RNC55H6191FPRSL in circuit design?

A: Yes. Both parts are electrically and mechanically identical, with matching resistance values (6.19 kOhms ±1%), power ratings (0.125W), temperature coefficients (±50ppm/°C), operating ranges (-65°C to 175°C), and physical dimensions (0.094" Dia x 0.250" L). The difference in packaging format (Tape & Reel versus Bulk) does not affect circuit performance.

Q: What is the significance of the different failure rate classifications?

A: The RNC55H6191FPRSL carries a P-class failure rate (0.1%), while RNC55H6191FSB14 carries an S-class failure rate (0.001%). The S-class rating indicates a lower predicted failure rate and may be selected for applications requiring extended service life or higher reliability assurance. Both classifications comply with military standards.

Q: Are there any compliance differences between these parts?

A: Both parts share identical compliance status: RoHS non-compliant, REACH Affected, and ECCN EAR99 classification. No compliance advantage exists between the two options.

Q: Which packaging format should be selected for manual assembly?

A: The Bulk packaging format (RNC55H6191FSB14) is typically more suitable for manual assembly and small-batch production. The Tape & Reel format (RNC55H6191FPRSL) is optimized for automated pick-and-place assembly systems.

Q: Do these parts require any special handling or storage considerations?

A: Both parts are rated as Moisture Sensitivity Level Not Applicable, indicating standard handling and storage conditions are acceptable without special moisture control measures.
