Substitute Part Grouping Explanation

Substitution for the RLR05C8873FPRSL is determined by strict equivalence across the following parameters:

• Resistance value: 887 kOhms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Composition: Metal Film
• Package: Axial
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -65°C to 150°C
• Series compliance: MIL-PRF-39017/05, RLR05
• Physical dimensions: 0.066" Dia x 0.150" L (1.68mm x 3.81mm)
• Termination count: 2

The identified substitute maintains identical electrical specifications and mechanical form factor. Packaging configuration (Tape & Reel versus bulk) does not affect functional equivalence for component-level substitution.

Parameter Comparison

Engineering Selection Recommendations

The RLR05C8873FRRSL is a direct functional equivalent to the discontinued RLR05C8873FPRSL. Both parts are manufactured by Vishay Dale within the same military-grade RLR05 series and meet MIL-PRF-39017/05 specifications. The substitute part is currently in active production status, ensuring procurement availability.

Both parts carry identical RoHS non-compliant and REACH Affected designations, maintaining regulatory consistency. The substitute exhibits a lower failure rate (R at 0.01% versus P at 0.1%), indicating improved reliability performance. Packaging differs only in format (Tape & Reel for the substitute versus bulk for the main part), which does not affect electrical or mechanical compatibility at the component level.

Frequently Asked Questions (FAQ)

Q: Can RLR05C8873FRRSL be used as a direct replacement for RLR05C8873FPRSL?

A: Yes. Both parts are electrically and mechanically identical, with matching resistance, tolerance, power rating, temperature coefficient, operating range, and physical dimensions. The substitute is manufactured by the same supplier within the same military series.

Q: What is the difference between the two part numbers?

A: The primary difference is packaging configuration. RLR05C8873FPRSL is supplied in bulk packaging, while RLR05C8873FRRSL is supplied in Tape & Reel format. This affects procurement and handling but not component performance or circuit compatibility.

Q: Are there compliance or certification differences?

A: Both parts share identical RoHS and REACH status designations. Both are classified under ECCN EAR99 and HTSUS 8533.21.0090. No compliance differences exist between the two parts.

Q: Why does the substitute have a different failure rate?

A: The substitute carries a lower failure rate classification (R at 0.01% versus P at 0.1%), indicating improved reliability characteristics within the same military specification framework. This represents a performance advantage for the substitute part.

Q: Is the substitute part currently available?

A: Yes. RLR05C8873FRRSL maintains active product status with current inventory availability, whereas the main part is discontinued at DiGi Electronics.
