Substitute Part Grouping Explanation

Substitution eligibility for the RLR32C1001FMBSL is determined by strict equivalence across the following critical parameters:

• Resistance value: 1 kOhms
• Tolerance: ±1%
• Power rating: 1W
• Composition: Metal Film
• Package type: Axial
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -65°C ~ 150°C
• Military series compliance: MIL-PRF-39017/03, RLR32
• Physical dimensions: 0.190" Dia x 0.562" L (4.83mm x 14.27mm)
• Number of terminations: 2

The identified substitute part maintains all electrical and mechanical specifications identical to the main part. Variations in failure rate classification and packaging designations do not affect functional equivalence within the same military-grade resistor series.

Parameter Comparison

Engineering Selection Recommendations

Both RLR32C1001FMBSL and RLR32C1001FRB14 are active production parts from Vishay Dale within the military-grade RLR32 series. Selection between these parts should be based on the following factors:

RLR32C1001FMBSL is appropriate for applications where the specified failure rate classification of M (1%) aligns with system reliability requirements and inventory availability of 1064 units supports procurement timelines.

RLR32C1001FRB14 is appropriate for applications requiring enhanced reliability performance, as indicated by the lower failure rate classification of R (0.01%), with 877 units currently available. This part maintains identical electrical and mechanical specifications while offering improved failure rate characteristics within the same military series.

Both parts maintain compliance with MIL-PRF-39017/03, RoHS non-compliant status, REACH affected designation, EAR99 export classification, and HTSUS code 8533.21.0090. Selection does not introduce compliance or certification conflicts.

Frequently Asked Questions (FAQ)

Q: Can RLR32C1001FRB14 be used as a direct replacement for RLR32C1001FMBSL?

A: Yes. Both parts are electrically and mechanically equivalent. They share identical resistance value (1 kOhms), tolerance (±1%), power rating (1W), temperature coefficient (±100ppm/°C), operating temperature range (-65°C ~ 150°C), physical dimensions (0.190" Dia x 0.562" L), and military series compliance (MIL-PRF-39017/03, RLR32). The primary difference is the failure rate classification, where RLR32C1001FRB14 offers R (0.01%) versus M (1%).

Q: What is the significance of the different failure rate classifications?

A: Failure rate classification indicates the expected percentage of parts that may fail under specified conditions. RLR32C1001FRB14 with R (0.01%) classification represents lower expected failure rate compared to RLR32C1001FMBSL with M (1%) classification. Selection should align with system reliability and mission-critical requirements.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts have identical axial package dimensions of 0.190" Dia x 0.562" L (4.83mm x 14.27mm), ensuring compatibility with existing PCB layouts and mechanical assemblies without modification.

Q: Do these parts have different compliance or certification status?

A: No. Both parts maintain identical compliance status: RoHS non-compliant, REACH affected, EAR99 export classification, and HTSUS code 8533.21.0090. No compliance conflicts exist between these parts.

Q: What is the difference between the packaging designations FMBSL and FRB14?

A: The packaging designations indicate different packaging configurations within the bulk supply category. Both parts are supplied in bulk packaging and maintain identical electrical and mechanical specifications. The designation difference does not affect functional performance or substitution eligibility.
