Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RLR05C1502FMB14 is determined by strict equivalence across the following parameters: resistance value (15 kOhms), tolerance (±1%), power rating (0.125W), composition (metal film), temperature coefficient (±100ppm/°C), operating temperature range (-65°C to 150°C), package type (axial), physical dimensions (0.066" Dia x 0.150" L), and military series classification (MIL-PRF-39017/05, RLR05). The substitute part RLR05C1502FSB14 maintains all these electrical and mechanical specifications. The primary distinction between the main part and its substitute is the failure rate classification: the main part carries an M-grade failure rate (1%), while the substitute carries an S-grade failure rate (0.001%). Both parts are manufactured by Vishay Dale and remain active products with current production status.

Parameter Comparison

Engineering Selection Recommendations

Both RLR05C1502FMB14 and RLR05C1502FSB14 are active military-grade resistors from Vishay Dale's RLR05 series, manufactured to MIL-PRF-39017/05 specifications. Selection between these parts should be based on application-specific reliability requirements. The RLR05C1502FMB14 with M-grade failure rate (1%) is suitable for standard military applications. The RLR05C1502FSB14 with S-grade failure rate (0.001%) provides enhanced reliability for high-reliability applications where lower failure rates are mandated. Both parts carry identical RoHS non-compliance and REACH-affected status, requiring equivalent compliance documentation. Current inventory availability shows 1607 units of RLR05C1502FSB14 versus 1112 units of RLR05C1502FMB14.

Frequently Asked Questions (FAQ)

Q: Can RLR05C1502FSB14 be used as a direct replacement for RLR05C1502FMB14?

A: Yes. Both parts maintain identical electrical specifications (15 kOhms ±1%, 0.125W, ±100ppm/°C, -65°C to 150°C operating range) and mechanical dimensions (0.066" Dia x 0.150" L axial package). The difference in failure rate classification does not affect functional compatibility.

Q: What is the difference between M-grade and S-grade failure rates?

A: M-grade carries a 1% failure rate specification, while S-grade carries a 0.001% failure rate specification. S-grade represents higher reliability performance and is selected for applications requiring enhanced dependability.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts are 0.066" diameter by 0.150" length axial resistors with identical termination configuration (2 terminations), ensuring mechanical interchangeability in PCB layouts and through-hole applications.

Q: Do both parts meet the same military specifications?

A: Yes. Both RLR05C1502FMB14 and RLR05C1502FSB14 are manufactured to MIL-PRF-39017/05 specifications and belong to the RLR05 military resistor series with identical moisture-resistant and weldable features.

Q: What compliance considerations apply to both parts?

A: Both parts are RoHS non-compliant and REACH-affected, requiring equivalent regulatory documentation. Both carry EAR99 export classification and 8533.21.0090 HTSUS code.
