Substitute Part Grouping Explanation

Substitution eligibility for the RLR07C1001FSRSL is determined by strict equivalence across all electrical and mechanical parameters. The primary differentiator between the main part and its substitute is packaging format. Both the main part (RLR07C1001FSRSL) and substitute part (RLR07C1001FSRE6) share identical specifications for resistance value, tolerance, power rating, composition, temperature coefficient, operating temperature range, physical dimensions, series designation, failure rate, and features. The only distinction is the supply packaging: the main part is supplied in Tape & Reel (TR) format, while the substitute is supplied in Cut Tape (CT) format. This packaging difference does not affect component performance, electrical characteristics, or mechanical compatibility in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both RLR07C1001FSRSL and RLR07C1001FSRE6 are active production components from Vishay Dale with identical electrical performance and military-grade specifications. Selection between these parts should be based on procurement requirements and assembly process compatibility. The Tape & Reel format (RLR07C1001FSRSL) is suitable for high-volume automated assembly operations, while the Cut Tape format (RLR07C1001FSRE6) accommodates lower-volume or manual assembly workflows. Both parts maintain equivalent compliance status with RoHS non-compliance and REACH Affected designations. Inventory availability may influence selection, with 1891 units of the Cut Tape variant currently in stock compared to 909 units of the Tape & Reel variant.

Frequently Asked Questions (FAQ)

Q: Can RLR07C1001FSRE6 be used as a direct replacement for RLR07C1001FSRSL in circuit design?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (Cut Tape versus Tape & Reel), which does not affect circuit performance or component functionality.

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

A: Tape & Reel packaging supplies components on continuous carrier tape wound on a reel, optimized for automated pick-and-place assembly. Cut Tape packaging supplies the same components on shorter tape segments, suitable for manual assembly or lower-volume production runs.

Q: Are there any compatibility issues when substituting between these two part numbers?

A: No compatibility issues exist. Both parts have identical physical dimensions (0.090" Dia x 0.250" L), axial lead configuration, and electrical specifications. The substitution is valid for any application requiring a 1 kOhms ±1% metal film resistor rated at 0.25W.

Q: Do both parts meet the same military specifications?

A: Yes. Both RLR07C1001FSRSL and RLR07C1001FSRE6 are manufactured to MIL-PRF-39017/01 specification with identical military-grade features including moisture resistance, weldability, and S-class failure rate (0.001%).

Q: Which part should be selected for high-volume production?

A: RLR07C1001FSRSL (Tape & Reel format) is recommended for high-volume automated assembly due to its continuous reel packaging, which integrates seamlessly with automated pick-and-place equipment.

Q: Which part should be selected for low-volume or prototype applications?

A: RLR07C1001FSRE6 (Cut Tape format) is suitable for low-volume or prototype applications where manual component handling or smaller batch quantities are required.
