Substitute Part Grouping Explanation

Substitution eligibility for the RLR07C1001FMB14 is determined by strict equivalence across the following critical parameters:

• Resistance value: 1 kOhms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Composition: Metal Film
• Package: Axial
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -65°C to 150°C
• Physical dimensions: 0.090" Dia x 0.250" L
• Series compliance: MIL-PRF-39017/01, RLR07 base product

The RLR07C1001FRB14 meets all electrical and mechanical requirements for direct substitution. Both parts share identical base specifications, military series designation, and physical form factor. The primary distinction lies in failure rate classification, which does not affect functional compatibility in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both RLR07C1001FMB14 and RLR07C1001FRB14 are active production parts manufactured by Vishay Dale under identical military specifications. Selection between these parts should be based on:

• Inventory availability and lead time requirements
• Failure rate specifications for the application (M-level at 1% versus R-level at 0.01%)
• Compliance requirements: Both parts maintain identical RoHS non-compliant and REACH Affected status
• Export control classification: Both parts are classified as EAR99

The RLR07C1001FRB14 offers improved reliability through lower failure rate classification, making it suitable for applications requiring enhanced long-term performance predictability. The RLR07C1001FMB14 remains fully qualified for standard military applications where the M-level failure rate meets specification requirements.

Frequently Asked Questions (FAQ)

Q: Can RLR07C1001FRB14 be used as a direct replacement for RLR07C1001FMB14?

A: Yes. Both parts are electrically and mechanically identical across all functional parameters: 1 kOhms resistance, ±1% tolerance, 0.25W power rating, metal film composition, axial package, and identical physical dimensions. The difference in failure rate classification does not affect circuit compatibility.

Q: What is the significance of the failure rate difference between M (1%) and R (0.01%)?

A: Failure rate classification indicates the expected percentage of parts that may fail under specified conditions over a defined time period. The R-level (0.01%) represents lower failure rate than M-level (1%), providing enhanced reliability for applications requiring extended operational life or critical performance requirements.

Q: Are there any package or footprint differences between these parts?

A: No. Both parts share identical axial package configuration with dimensions of 0.090" diameter by 0.250" length (2.29mm x 6.35mm). PCB layout and mounting considerations are identical.

Q: Do both parts meet the same military specifications?

A: Yes. Both parts comply with MIL-PRF-39017/01 military specifications and are designated as RLR07 series components. They share identical temperature coefficient (±100ppm/°C), operating temperature range (-65°C to 150°C), and military-grade construction features including moisture resistance and weldability.

Q: Are there compliance or export control differences?

A: No. Both parts maintain identical RoHS non-compliant status, REACH Affected designation, EAR99 export classification, and HTSUS code 8533.21.0090.
