Substitute Part Grouping Explanation

Substitute parts for the RLR05C1001GMB14 are classified based on the following criteria:

Direct Equivalent (Same Specifications):

• RLR05C1001GRB14: Identical electrical and mechanical specifications with improved failure rate (R: 0.01% vs. M: 1%)

Upgrade Options (Enhanced Tolerance):

• RLR05C1001FRB14: Tighter tolerance specification (±1% vs. ±2%) with improved failure rate (R: 0.01%)
• RLR05C1001FSB14: Tighter tolerance specification (±1% vs. ±2%) with superior failure rate (S: 0.001%)

All substitute parts maintain identical resistance value, power rating, composition, package type, temperature coefficient, operating temperature range, and military qualification. Substitution is permissible where the tolerance and failure rate improvements are compatible with circuit requirements.

Parameter Comparison

Engineering Selection Recommendations

Selection among RLR05C1001GMB14 and its substitutes is determined by tolerance and reliability requirements:

RLR05C1001GMB14 (Original): Use where ±2% tolerance meets circuit specifications and standard military failure rate (M: 1%) is acceptable.

RLR05C1001GRB14 (Direct Equivalent): Direct replacement with improved reliability (R: 0.01% failure rate) while maintaining ±2% tolerance specification.

RLR05C1001FRB14 (Upgrade): Select when circuit design requires ±1% tolerance with improved reliability (R: 0.01% failure rate).

RLR05C1001FSB14 (Premium Upgrade): Select when circuit design requires ±1% tolerance with superior reliability (S: 0.001% failure rate) for high-reliability applications.

All parts are RoHS non-compliant, REACH affected, and classified under ECCN EAR99. All maintain active production status with adequate inventory availability.

Frequently Asked Questions (FAQ)

Q: Can RLR05C1001GRB14 be used as a direct replacement for RLR05C1001GMB14? A: Yes. RLR05C1001GRB14 is a direct equivalent with identical electrical and mechanical specifications. The improved failure rate (R: 0.01% vs. M: 1%) provides enhanced reliability without circuit impact.

Q: What is the difference between the ±2% and ±1% tolerance options? A: Tolerance defines the maximum deviation from the nominal 1 kOhms resistance value. ±2% allows ±20 ohms deviation; ±1% allows ±10 ohms deviation. Select ±1% tolerance (RLR05C1001FRB14 or RLR05C1001FSB14) for precision circuits requiring tighter resistance control.

Q: Are all substitute parts in the same axial package? A: Yes. All substitute parts maintain the identical 0.066" diameter by 0.150" length axial package, ensuring mechanical compatibility with existing PCB layouts and through-hole mounting.

Q: What does the failure rate designation mean? A: Failure rate follows military standards: M (1%), R (0.01%), and S (0.001%) represent decreasing failure rates per 1000 hours of operation. Higher reliability grades (R, S) are suitable for critical applications.

Q: Are these parts suitable for military applications? A: Yes. All parts are qualified to MIL-PRF-39017/05 military specification and feature moisture resistance and weldability required for military environments.
