Substitute Part Grouping Explanation

The RLR05C1001FSRE6 is classified as a parametric equivalent to the RLR05C1001FSRSL19. Substitution eligibility is determined by the following criteria:

Electrical Parameters (Must Match Exactly):

• Resistance value: 1 kOhms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -65°C to 150°C

Mechanical Parameters (Must Match Exactly):

• Composition: Metal Film
• Package type: Axial
• Physical dimensions: 0.066" Dia × 0.150" L (1.68mm × 3.81mm)
• Number of terminations: 2

Series & Compliance (Must Match Exactly):

• Military classification: MIL-PRF-39017/05, RLR05 series
• Failure rate: S (0.001%)

Variable Parameter (Allows Substitution):

• Packaging format: Tape & Reel (TR) vs. Cut Tape (CT)

The RLR05C1001FSRE6 differs only in packaging format (Cut Tape instead of Tape & Reel), making it suitable for applications where packaging method does not impact assembly or storage requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the RLR05C1001FSRSL19 and RLR05C1001FSRE6 are active production components from Vishay Dale with identical electrical and mechanical specifications. Selection between these parts should be based on the following factors:

Packaging Considerations: The primary difference is packaging format. The RLR05C1001FSRSL19 is supplied in Tape & Reel format, suitable for automated assembly processes. The RLR05C1001FSRE6 is supplied in Cut Tape format, suitable for manual assembly or lower-volume applications.

Compliance & Certification: Both parts maintain identical compliance status: RoHS non-compliant, REACH Affected, ECCN EAR99, and HTSUS 8533.21.0090. Military classification (MIL-PRF-39017/05) and failure rate (S, 0.001%) are identical.

Inventory & Availability: The RLR05C1001FSRE6 currently has higher inventory (1532 units) compared to the RLR05C1001FSRSL19 (1165 units). Selection may be influenced by supply chain requirements and lead time considerations.

Frequently Asked Questions (FAQ)

Q: Can the RLR05C1001FSRE6 be used as a direct replacement for the RLR05C1001FSRSL19?

A: Yes, the RLR05C1001FSRE6 is a direct parametric equivalent. All electrical specifications, mechanical dimensions, and military certifications are identical. The only difference is packaging format (Cut Tape vs. Tape & Reel).

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

A: Tape & Reel packaging is designed for automated pick-and-place assembly equipment and is supplied on continuous reels. Cut Tape packaging is supplied in shorter tape segments and is typically used for manual assembly or lower-volume production runs. Both formats contain the same component.

Q: Are there any assembly compatibility issues when switching between these parts?

A: No compatibility issues exist for manual assembly. For automated assembly, the packaging format difference may require equipment reconfiguration. Tape & Reel format is optimized for automated feeders, while Cut Tape requires manual feeding or different feeder equipment.

Q: Do both parts meet military specifications?

A: Yes. Both the RLR05C1001FSRSL19 and RLR05C1001FSRE6 are classified as Military series components compliant with MIL-PRF-39017/05 and carry the same failure rate classification (S, 0.001%).

Q: What are the key parameters that must match for substitution?

A: Resistance value (1 kOhms), tolerance (±1%), power rating (0.125W), temperature coefficient (±100ppm/°C), operating temperature range (-65°C to 150°C), composition (Metal Film), axial package type, and physical dimensions (0.066" Dia × 0.150" L) must all match exactly. Packaging format is the only variable parameter allowing substitution.
