Substitute Part Grouping Explanation

The RLR05C1001FSRE819 and RLR05C1001FSRE6 are parametric equivalents differentiated solely by packaging format. Both components share identical electrical characteristics (1 kOhms resistance, ±1% tolerance, 0.125W power rating, metal film composition, ±100ppm/°C temperature coefficient, and -65°C to 150°C operating range). The primary distinction is packaging: RLR05C1001FSRE819 is supplied in Tape & Reel (TR) format, while RLR05C1001FSRE6 is supplied in Cut Tape (CT) format. Both maintain the same axial through-hole configuration, physical dimensions (0.066" Dia x 0.150" L), military series classification (MIL-PRF-39017/05), and failure rate specification (S, 0.001%). Substitution is valid when packaging format flexibility is acceptable for assembly and procurement requirements.

Parameter Comparison

Engineering Selection Recommendations

Both RLR05C1001FSRE819 and RLR05C1001FSRE6 are active production components suitable for military and high-reliability applications. Selection between these parts should be based on assembly process requirements and packaging handling capabilities. Tape & Reel (TR) format is optimized for automated pick-and-place assembly systems, while Cut Tape (CT) format accommodates manual assembly or lower-volume production runs. Both parts maintain identical compliance status (RoHS non-compliant, REACH Affected) and military series certification (MIL-PRF-39017/05). Inventory availability should be evaluated: RLR05C1001FSRE819 has 852 units in stock, while RLR05C1001FSRE6 has 1532 units in stock.

Frequently Asked Questions (FAQ)

Q: Can RLR05C1001FSRE6 be used as a direct replacement for RLR05C1001FSRE819?

A: Yes. Both parts are parametric equivalents with identical electrical specifications (1 kOhms, ±1%, 0.125W, metal film, ±100ppm/°C, -65°C to 150°C). The only difference is packaging format: Tape & Reel versus Cut Tape. Substitution is valid provided the assembly process can accommodate the different packaging format.

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

A: Tape & Reel (TR) format supplies components on continuous carrier tape wound on a reel, designed for automated assembly equipment. Cut Tape (CT) format supplies components on tape segments cut to specific lengths, suitable for manual assembly or lower-volume applications. Both formats contain identical components with the same electrical and mechanical properties.

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

A: No. Both parts share identical compliance status: RoHS non-compliant, REACH Affected, ECCN EAR99, and HTSUS 8533.21.0090. Both are certified to MIL-PRF-39017/05 military standards with S-class failure rate (0.001%).

Q: Which part should be selected based on inventory availability?

A: RLR05C1001FSRE6 (Cut Tape) has higher inventory (1532 units) compared to RLR05C1001FSRE819 (Tape & Reel, 852 units). If supply chain continuity is a priority and assembly process flexibility exists, the Cut Tape variant may offer better availability.

Q: Do these parts have identical physical dimensions?

A: Yes. Both parts have identical axial through-hole configuration with dimensions of 0.066" Dia x 0.150" L (1.68mm x 3.81mm). PCB layout and mechanical mounting are identical.
