Substitute Part Grouping Explanation

Substitution eligibility for the RNC50K2001FPRSL is determined by strict equivalence across the following critical parameters:

• Resistance value: 2 kOhms
• Tolerance: ±1%
• Power rating: 0.1W (1/10W)
• Composition: Metal Film
• Package type: Axial
• Physical dimensions: 0.070" Dia x 0.150" L (1.78mm x 3.81mm)
• Operating temperature range: -65°C ~ 175°C
• Number of terminations: 2
• Series compliance: MIL-PRF-55182/07, RNC50 base product

The identified substitute parts RNC50H2001FSB14 and RNC50H2001FSRE6 meet all electrical and mechanical requirements for direct substitution. Differences in packaging format (Bulk and Cut Tape versus Tape & Reel) and enhanced reliability metrics do not affect functional compatibility in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active production status with Vishay Dale and comply with MIL-PRF-55182/07 military specifications. The RNC50H2001FSB14 and RNC50H2001FSRE6 substitutes offer improved reliability metrics with failure rates of S (0.001%) compared to the main part's P (0.1%) rating, along with superior temperature coefficient stability at ±50ppm/°C versus ±100ppm/°C. Selection between substitute options depends on packaging requirements: RNC50H2001FSB14 is supplied in Bulk format, while RNC50H2001FSRE6 is available in Cut Tape format. Both substitutes provide higher inventory availability and are suitable for direct circuit replacement without design modification.

Frequently Asked Questions (FAQ)

Q: Can RNC50H2001FSB14 and RNC50H2001FSRE6 be used interchangeably with RNC50K2001FPRSL?

A: Yes. All three parts share identical electrical specifications (2 kOhms ±1%, 0.1W metal film), mechanical dimensions (0.070" Dia x 0.150" L), and operating temperature range (-65°C ~ 175°C). Differences in packaging format do not affect circuit functionality.

Q: What is the significance of the different temperature coefficients?

A: The main part RNC50K2001FPRSL has a temperature coefficient of ±100ppm/°C, while substitutes RNC50H2001FSB14 and RNC50H2001FSRE6 specify ±50ppm/°C. Both values are within acceptable ranges for military-grade applications. The lower coefficient in substitute parts indicates tighter resistance stability across temperature variations.

Q: How do failure rates differ between these parts?

A: The main part carries a failure rate of P (0.1%), while both substitutes carry a failure rate of S (0.001%). Lower failure rates indicate higher reliability. This difference reflects manufacturing process improvements in the substitute variants.

Q: What packaging formats are available?

A: RNC50K2001FPRSL is supplied in Tape & Reel (TR) format. RNC50H2001FSB14 is available in Bulk packaging, and RNC50H2001FSRE6 is supplied in Cut Tape (CT) format. Selection depends on assembly process requirements and handling preferences.

Q: Are all parts RoHS compliant?

A: No. All three parts are RoHS non-compliant, consistent with their military-grade metal film construction and MIL-PRF-55182/07 specification.

Q: Which substitute offers the best inventory availability?

A: RNC50H2001FSRE6 provides the highest inventory with 1883 pieces available, followed by RNC50H2001FSB14 with 1085 pieces. The main part RNC50K2001FPRSL has 750 pieces in stock.
