Substitute Part Grouping Explanation

Substitution of the RLR07C3012FMB14 is determined by strict equivalence across the following critical parameters:

• Resistance value: 30.1 kOhms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Composition: Metal Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -65°C to 150°C
• Package configuration: Axial
• Physical dimensions: 0.090" Dia × 0.250" L
• Military specification compliance: MIL-PRF-39017/01
• Base product series: RLR07

The identified substitute part RLR07C3012FSB14 maintains identical electrical specifications and mechanical compatibility. The distinction between the main part and substitute lies in the failure rate classification and inventory availability, not in functional or physical characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both RLR07C3012FMB14 and RLR07C3012FSB14 are active production components manufactured by Vishay Dale under military specification MIL-PRF-39017/01. Selection between these parts should be based on the following criteria:

The RLR07C3012FSB14 offers a lower failure rate classification (S at 0.001% versus M at 1%), making it suitable for applications with stringent reliability requirements. This part also maintains higher inventory availability at 1312 pieces compared to 661 pieces for the RLR07C3012FMB14.

Both parts carry identical RoHS non-compliant and REACH Affected status. Neither part is subject to moisture sensitivity level classification. Both are classified under ECCN EAR99 and HTSUS 8533.21.0090.

Selection should prioritize application reliability requirements and supply chain considerations rather than electrical performance, as both parts are electrically and mechanically equivalent.

Frequently Asked Questions (FAQ)

Q: Can RLR07C3012FSB14 be used as a direct replacement for RLR07C3012FMB14?
