Key Parameters

Substitute Part Grouping Explanation

Substitution of the RLR07C1003FSK36 is determined by the following critical parameters:

• Electrical Specifications: Resistance value (100 kOhms), tolerance (±1%), power rating (0.25W), and temperature coefficient (±100ppm/°C) must remain identical
• Composition & Construction: Metal film composition and axial package configuration must be maintained
• Environmental Performance: Operating temperature range (-65°C to 150°C), moisture resistance, and weldability features must be preserved
• Military Compliance: MIL-PRF-39017/01 series designation and failure rate classification (S) must be consistent
• Physical Compatibility: Axial package dimensions (0.090" Dia × 0.250" L) must match for PCB layout and assembly compatibility

The RLR07C1003FSRE5 qualifies as a parametric equivalent based on identical electrical and mechanical specifications. The primary difference is packaging format: the main part uses Tape & Reel (TR) packaging, while the substitute uses Cut Tape (CT) packaging. Both are sourced from the same manufacturer and series.

Parameter Comparison

Engineering Selection Recommendations

Both the RLR07C1003FSK36 and RLR07C1003FSRE5 are active production parts from Vishay Dale's military-grade RLR07 series. Selection between these parts should be based on procurement and assembly requirements:

• RLR07C1003FSK36 (Tape & Reel): Suitable for high-volume automated assembly operations where tape-and-reel packaging provides efficiency in pick-and-place equipment
• RLR07C1003FSRE5 (Cut Tape): Appropriate for lower-volume production runs, prototype builds, or applications where individual component handling is preferred

Both parts maintain identical electrical performance, military compliance per MIL-PRF-39017/01, and environmental specifications. The choice between them does not affect circuit functionality or reliability characteristics. Current inventory availability shows 854 units for the TR variant and 1175 units for the CT variant.

Frequently Asked Questions (FAQ)

Q: Can RLR07C1003FSRE5 be used as a direct replacement for RLR07C1003FSK36?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (Cut Tape versus Tape & Reel). They are interchangeable from a circuit design and performance perspective.

Q: What does the packaging format difference mean for assembly?

A: Tape & Reel (TR) packaging is optimized for automated pick-and-place assembly on production lines. Cut Tape (CT) packaging provides individual component access and is typically used for manual assembly, prototyping, or lower-volume production.

Q: Are both parts compliant with military specifications?

A: Yes. Both RLR07C1003FSK36 and RLR07C1003FSRE5 are manufactured to MIL-PRF-39017/01 specification and carry identical military-grade certifications, failure rate classifications, and environmental performance ratings.

Q: Will substituting between these parts affect PCB layout or assembly procedures?

A: No. Both parts have identical physical dimensions (0.090" Dia × 0.250" L) and axial package configuration. PCB footprints and assembly procedures remain unchanged.

Q: What is the significance of the failure rate classification "S"?

A: Failure rate class S (0.001%) indicates a low failure rate specification per military standards, ensuring high reliability for critical applications in aerospace and defense environments.

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

A: No. Both parts share identical RoHS status (non-compliant), REACH status (affected), ECCN (EAR99), and HTSUS classification (8533.21.0090).
