Substitute Part Grouping Explanation

The RLR05C1001FSRE6 is classified as a parametric equivalent to the RLR05C1001FSS20. Substitution is valid based on the following criteria:

Electrical Parameters (Identical):

• Resistance value: 1 kOhms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -65°C to 150°C
• Composition: Metal Film
• Failure rate: S (0.001%)

Mechanical Parameters (Identical):

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

Packaging Difference:

• RLR05C1001FSS20: Tape & Reel (TR)
• RLR05C1001FSRE6: Cut Tape (CT)

The only distinction between these parts is the packaging format. Both maintain identical electrical performance, military qualification, and physical form factor.

Parameter Comparison

Engineering Selection Recommendations

Both the RLR05C1001FSS20 and RLR05C1001FSRE6 are active production components from Vishay Dale with identical electrical and mechanical specifications. Selection between these parts should be based on packaging requirements and supply chain considerations:

• RLR05C1001FSS20 (Tape & Reel): Suitable for high-volume automated assembly processes requiring continuous tape feeding.
• RLR05C1001FSRE6 (Cut Tape): Suitable for lower-volume applications, manual assembly, or when tape & reel packaging is not required.

Both parts comply with MIL-PRF-39017/05 military specifications and maintain identical performance characteristics across all electrical and thermal parameters. Selection does not impact circuit performance or reliability.

Frequently Asked Questions (FAQ)

Q: Can RLR05C1001FSRE6 be used as a direct replacement for RLR05C1001FSS20?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (Cut Tape vs. Tape & Reel). Direct substitution is valid for any application where the packaging format is compatible with assembly equipment.

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

A: Tape & Reel (TR) packaging supplies components on continuous tape wound on a reel, suitable for automated pick-and-place assembly. Cut Tape (CT) packaging supplies components on tape segments, suitable for manual assembly or lower-volume production runs.

Q: Are both parts military qualified?

A: Yes. Both RLR05C1001FSS20 and RLR05C1001FSRE6 are qualified to MIL-PRF-39017/05 military specifications with identical failure rates and performance characteristics.

Q: Do these parts have the same physical dimensions?

A: Yes. Both parts measure 0.066" diameter × 0.150" length (1.68mm × 3.81mm) and are axial through-hole components with identical lead spacing and mounting requirements.

Q: Which part should be selected for new designs?

A: Selection should be based on assembly process requirements. For automated assembly, use Tape & Reel format. For manual assembly or prototyping, Cut Tape format is appropriate. Both parts are active and equally suitable for production use.
