Substitute Part Grouping Explanation

Substitution eligibility for the RLR07C1001FSRE523 is determined by strict equivalence across the following parameters: resistance value (1 kOhms), tolerance (±1%), power rating (0.25W), composition (metal film), temperature coefficient (±100ppm/°C), operating temperature range (-65°C to 150°C), axial package type, physical dimensions (0.090" Dia x 0.250" L), series designation (Military, MIL-PRF-39017/01, RLR07), and failure rate (S, 0.001%). The only allowable variation is packaging format: Tape & Reel (TR) versus Cut Tape (CT). Both formats contain identical components and meet all military specifications. This variation accommodates different assembly and procurement workflows without affecting electrical or mechanical performance.

Parameter Comparison

Engineering Selection Recommendations

Both RLR07C1001FSRE523 and RLR07C1001FSRE6 are active production parts from Vishay Dale with identical electrical and mechanical specifications. Selection between these parts is based on packaging requirements and supply availability. The RLR07C1001FSRE523 in Tape & Reel format is suitable for high-volume automated assembly operations. The RLR07C1001FSRE6 in Cut Tape format accommodates lower-volume builds or manual assembly workflows. Both parts maintain RoHS non-compliant and REACH Affected status, requiring compliance verification within your supply chain and end-use application. Current inventory shows 1891 pieces of RLR07C1001FSRE6 available versus 700 pieces of RLR07C1001FSRE523, which may influence procurement decisions based on project timeline and volume requirements.

Frequently Asked Questions (FAQ)

Q: Can RLR07C1001FSRE6 be used as a direct replacement for RLR07C1001FSRE523?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format: Tape & Reel versus Cut Tape. This variation does not affect component performance, electrical characteristics, or military specification compliance.

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

A: Tape & Reel (TR) packaging supplies components on continuous carrier tape wound on reels, optimized for automated pick-and-place assembly. Cut Tape (CT) packaging supplies the same components on shorter tape segments, suitable for manual assembly or lower-volume production runs. Both formats contain identical resistors meeting MIL-PRF-39017/01 specifications.

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

A: No. Both parts share identical resistance (1 kOhms), tolerance (±1%), power rating (0.25W), temperature coefficient (±100ppm/°C), operating temperature range (-65°C to 150°C), and failure rate (S, 0.001%). Physical dimensions and axial configuration are identical.

Q: Which part should I select for my application?

A: Selection depends on your assembly process and supply requirements. Use RLR07C1001FSRE523 (Tape & Reel) for automated assembly lines. Use RLR07C1001FSRE6 (Cut Tape) for manual assembly or prototyping. Both meet military specifications and are suitable for harsh environmental applications requiring moisture resistance and weldability.

Q: Are there any compliance considerations when substituting these parts?

A: Both parts carry identical compliance status: RoHS non-compliant and REACH Affected. Verify that your application and supply chain requirements accommodate these compliance designations before proceeding with either part.
