Substitute Part Grouping Explanation

The RLR05C1001FSRE619 and its identified substitute RLR05C1001FSRE6 are functionally equivalent 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
• Failure rate: S (0.001%)

Mechanical Parameters (Identical):

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

Differentiating Parameter:

• Packaging format: RLR05C1001FSRE619 is supplied in Tape & Reel (TR) format; RLR05C1001FSRE6 is supplied in Cut Tape (CT) format

Both parts conform to the same military specification (MIL-PRF-39017/05) and share identical electrical and mechanical characteristics. The substitution is valid for applications where packaging format does not impose constraints on assembly or procurement processes.

Parameter Comparison

Engineering Selection Recommendations

Both the RLR05C1001FSRE619 and RLR05C1001FSRE6 are active production components manufactured by Vishay Dale under the military specification MIL-PRF-39017/05. Selection between these parts should be based on packaging requirements and procurement constraints:

RLR05C1001FSRE619 (Tape & Reel): Suitable for high-volume automated assembly processes where tape-and-reel packaging provides efficiency in pick-and-place operations.

RLR05C1001FSRE6 (Cut Tape): Suitable for lower-volume applications, manual assembly, or situations where smaller packaging quantities are required. This variant currently has higher inventory availability (1532 units versus 796 units).

Both parts are RoHS non-compliant and REACH-affected, with identical compliance status. No electrical or mechanical redesign is required when substituting between these two part numbers.

Frequently Asked Questions (FAQ)

Q: Can RLR05C1001FSRE6 be used as a direct replacement for RLR05C1001FSRE619?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (Cut Tape versus Tape & Reel). Direct substitution is valid provided the receiving assembly process can accommodate the packaging format.

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

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

Q: Are there any performance differences between these two part numbers?

A: No. Both parts have identical electrical specifications (1 kOhms ±1%, 0.125W, ±100ppm/°C, -65°C to 150°C), identical mechanical dimensions (0.066" Dia x 0.150" L), and identical military qualification (MIL-PRF-39017/05).

Q: Do both parts meet the same military specifications?

A: Yes. Both RLR05C1001FSRE619 and RLR05C1001FSRE6 conform to MIL-PRF-39017/05 and carry the same failure rate classification S (0.001%).

Q: Which part should I select based on availability?

A: RLR05C1001FSRE6 (Cut Tape) currently has higher inventory (1532 units) compared to RLR05C1001FSRE619 (Tape & Reel, 796 units). Selection should prioritize your assembly process requirements first, then consider availability as a secondary factor.
