RNC50H2003FSR93 Equivalent & Substitute Parts

Part Overview

The RNC50H2003FSR93 is a 200 kOhms ±1% metal film axial through-hole resistor rated at 0.1W (1/10W) power dissipation. Manufactured by Vishay Dale under the military-grade RNC50 series (MIL-PRF-55182/07), this component is designed for applications requiring precision resistance with moisture resistance and weldability characteristics. The part is currently active in production with 1101 pieces available in stock. Substitute parts may be required due to packaging format availability, supply chain considerations, or specific procurement requirements while maintaining identical electrical and mechanical performance.

Substitute Part Grouping Explanation

Substitution of the RNC50H2003FSR93 is determined by strict equivalence across all critical electrical and mechanical parameters. The allowed substitution criteria are:

• Resistance value: 200 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.1W / 1/10W (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 type: Axial (exact match required)
• Physical dimensions: 0.070" Dia × 0.150" L (exact match required)
• Series: Military, MIL-PRF-55182/07, RNC50 (exact match required)
• Features: Military Grade, Moisture Resistant, Weldable (exact match required)
• Failure rate: S (0.001%) (exact match required)

The only allowable variation is packaging format (Tape & Reel versus Cut Tape), which does not affect component performance or circuit functionality.

Parameter Comparison

Engineering Selection Recommendations

The RNC50H2003FSRE6 is a direct electrical and mechanical equivalent to the RNC50H2003FSR93. Both components are manufactured by Vishay Dale, share identical electrical specifications, and are classified under the same military-grade RNC50 series with MIL-PRF-55182/07 compliance. The components are functionally interchangeable in all circuit applications.

The primary distinction between these parts is packaging format: the main part is supplied in Tape & Reel (TR) format, while the substitute is supplied in Cut Tape (CT) format. This difference affects only the procurement and handling method and does not impact electrical performance, reliability, or circuit compatibility.

Selection between these parts should be based on procurement requirements, assembly equipment compatibility, and inventory availability rather than technical performance criteria.

Frequently Asked Questions (FAQ)

Q: Can RNC50H2003FSRE6 be used as a direct replacement for RNC50H2003FSR93?

A: Yes. Both parts are electrically and mechanically identical. All electrical parameters, temperature characteristics, reliability ratings, and physical dimensions match exactly. The only difference is packaging format (Cut Tape versus Tape & Reel).

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

A: Tape & Reel (TR) packaging supplies components on a continuous reel suitable for automated pick-and-place assembly equipment. Cut Tape (CT) packaging supplies components on individual tape segments. Both formats contain the same component; the difference is in handling and assembly process compatibility.

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

A: No. Both parts carry identical military-grade classification (MIL-PRF-55182/07), failure rate rating (S at 0.001%), and feature set (Military Grade, Moisture Resistant, Weldable). RoHS compliance status is identical for both parts.

Q: Which part should be selected if both are available?

A: Selection should be based on assembly equipment capability and procurement logistics. If your assembly process uses automated equipment with tape-fed component handling, select the Tape & Reel format. If manual assembly or cut-tape compatible equipment is used, either format is acceptable. Inventory availability may also influence selection.

Q: Are the physical dimensions identical?

A: Yes. Both parts have identical axial package dimensions of 0.070" diameter × 0.150" length (1.78mm × 3.81mm). They are mechanically interchangeable in all PCB layouts and through-hole applications.
