Key Parameters

Substitute Part Grouping Explanation

Substitution for the RNR55H2002FSRSL is determined by maintaining the following critical parameters:

• Resistance value: 20 kOhms
• 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: 0.094" Dia x 0.250" L (2.39mm x 6.35mm)
• Military specification compliance: MIL-PRF-55182/01
• Failure rate: S (0.001%)

The RNC55H2002FSRE6 qualifies as a parametric equivalent substitute. Both parts share identical electrical specifications, physical dimensions, and military-grade performance characteristics. The primary distinction is packaging format: the RNR55H2002FSRSL is supplied in Tape & Reel (TR) configuration, while the RNC55H2002FSRE6 is available in Cut Tape (CT) packaging. The RNC55 series additionally incorporates weldable construction, an enhanced feature that does not affect core electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the RNR55H2002FSRSL and RNC55H2002FSRE6 maintain active production status and are fully compliant with MIL-PRF-55182/01 military specifications. Selection between these parts should be based on procurement and assembly requirements:

The RNR55H2002FSRSL in Tape & Reel packaging is suitable for high-volume automated assembly operations where continuous reel feeding is required.

The RNC55H2002FSRE6 in Cut Tape packaging accommodates lower-volume production runs, manual assembly processes, or applications where individual component handling is preferred. The addition of weldable construction in the RNC55 series provides enhanced termination options for specialized assembly methods.

Both parts carry identical electrical performance, temperature stability, and military-grade reliability ratings. RoHS non-compliance status is consistent across both options. No functional or performance trade-offs exist between these substitutes.

Frequently Asked Questions (FAQ)

Q: Can RNC55H2002FSRE6 be used as a direct replacement for RNR55H2002FSRSL in existing designs?

A: Yes. Both parts are electrically and mechanically identical with matching resistance values, tolerances, power ratings, temperature coefficients, and operating ranges. The difference is packaging format only. Physical dimensions and termination characteristics are identical, ensuring direct compatibility in circuit applications.

Q: What is the significance of the weldable feature in the RNC55H2002FSRE6?

A: The weldable construction in the RNC55 series enables alternative termination and assembly methods. This feature does not affect electrical performance or compatibility with standard soldering processes. It provides additional flexibility for specialized manufacturing environments.

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

A: No. Both parts share identical military specification compliance (MIL-PRF-55182/01), failure rate ratings (S 0.001%), RoHS status (non-compliant), and export classification (EAR99). Certification and regulatory standing are equivalent.

Q: How do packaging formats affect component selection?

A: Tape & Reel (TR) packaging is optimized for automated pick-and-place assembly at high volumes, where continuous reel feeding improves throughput. Cut Tape (CT) packaging is suitable for lower-volume production, manual assembly, or applications requiring individual component handling. Both formats contain identical components with no electrical or mechanical differences.

Q: Is inventory availability a factor in substitution decisions?

A: Inventory levels may influence procurement timing but do not affect technical substitution validity. The RNR55H2002FSRSL has 1098 units in stock, while the RNC55H2002FSRE6 has 1127 units available. Both parts maintain active production status.
