Substitute Part Grouping Explanation

Substitute parts for the RLR05C1001FMB14 are qualified based on the following criteria:

• Identical resistance value: 1 kOhms
• Identical tolerance: ±1%
• Identical power rating: 0.125W (1/8W)
• Identical composition: Metal Film
• Identical package type: Axial
• Identical temperature coefficient: ±100ppm/°C
• Identical operating temperature range: -65°C to 150°C
• Identical physical dimensions: 0.066" Dia x 0.150" L (1.68mm x 3.81mm)
• Same military series qualification: MIL-PRF-39017/05, RLR05
• Same features: Military, Moisture Resistant, Weldable

The substitute parts differ only in failure rate classification, which reflects manufacturing process variations within the same military specification. All substitutes maintain full electrical and mechanical compatibility with the primary part number.

Parameter Comparison

Engineering Selection Recommendations

All three part numbers—RLR05C1001FMB14, RLR05C1001FRB14, and RLR05C1001FSB14—are functionally equivalent for circuit applications requiring a 1 kOhms ±1% metal film axial resistor. Selection between these parts should be based on failure rate requirements and application reliability specifications:

• RLR05C1001FMB14 (Failure Rate M, 1%): Suitable for standard military applications with baseline reliability requirements.
• RLR05C1001FRB14 (Failure Rate R, 0.01%): Appropriate for applications requiring enhanced reliability with lower failure rate classification.
• RLR05C1001FSB14 (Failure Rate S, 0.001%): Specified for high-reliability and mission-critical applications demanding the lowest failure rate within the RLR05 series.

All parts maintain identical electrical performance, mechanical compatibility, and compliance certifications. Inventory availability should be considered in conjunction with failure rate requirements for procurement decisions.

Frequently Asked Questions (FAQ)

Q: Can RLR05C1001FRB14 and RLR05C1001FSB14 be used interchangeably with RLR05C1001FMB14?

A: Yes. All three part numbers are electrically and mechanically identical. They differ only in failure rate classification. Any part can substitute for another in the same circuit application, provided the failure rate requirement is met or exceeded.

Q: What does the failure rate designation mean?

A: Failure rate classifications (M, R, S) indicate the expected percentage of component failures per 1000 hours of operation under specified conditions. M (1%) represents standard military reliability, R (0.01%) represents enhanced reliability, and S (0.001%) represents high reliability. Higher reliability grades are suitable for more demanding applications.

Q: Are these parts suitable for RoHS-compliant applications?

A: No. All three part numbers are RoHS non-compliant. Applications requiring RoHS compliance must source alternative components from different product lines.

Q: What is the physical footprint compatibility?

A: All three parts share identical axial package dimensions of 0.066" diameter by 0.150" length (1.68mm x 3.81mm). They are mechanically interchangeable on PCBs designed for axial through-hole resistors.

Q: Are these parts suitable for high-temperature applications?

A: Yes. All three parts operate across the temperature range of -65°C to 150°C with a temperature coefficient of ±100ppm/°C, making them suitable for military and aerospace applications requiring extended temperature performance.

Q: What is the REACH and ECCN status?

A: All three parts are REACH Affected and classified under ECCN EAR99, indicating they are subject to export control regulations and REACH chemical substance restrictions.
