Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RLR07C2002GPB14 are qualified based on the following criteria:

Electrical Compatibility: All substitute parts maintain the same 20 kOhms resistance value, 0.25W power rating, metal film composition, temperature coefficient, and operating temperature range. These parameters are non-negotiable for direct substitution.

Mechanical Compatibility: All substitute parts share identical axial package configuration and physical dimensions (0.090" Dia x 0.250" L), ensuring compatibility with existing PCB layouts and assembly processes.

Military Specification Compliance: All parts conform to MIL-PRF-39017/01 and belong to the RLR07 series, maintaining military-grade moisture resistance and weldability.

Tolerance and Reliability Variations: Substitute parts are differentiated by tolerance specification and failure rate classification, allowing selection based on application precision requirements and reliability targets.

Parameter Comparison

Engineering Selection Recommendations

RLR07C2002GSB14 (Direct Equivalent): This part is electrically and mechanically identical to the RLR07C2002GPB14, with the same ±2% tolerance specification. The primary distinction is the improved failure rate classification (S: 0.001% versus P: 0.1%), indicating enhanced reliability performance. This part is suitable for applications where the original specification is maintained with the benefit of superior reliability metrics. Higher inventory availability (1312 units) supports procurement flexibility.

RLR07C2002FSB14 (Upgrade Option): This part provides tighter tolerance specification (±1% versus ±2%) while maintaining all other electrical and mechanical parameters. The failure rate classification is also improved to S (0.001%). Selection of this part is appropriate for applications requiring enhanced precision in resistance value without modification to circuit design or PCB layout. All military compliance certifications and environmental specifications remain equivalent.

Frequently Asked Questions (FAQ)

Q: Can RLR07C2002GSB14 be used as a direct replacement for RLR07C2002GPB14?

A: Yes. Both parts are identical in resistance value (20 kOhms), tolerance (±2%), power rating (0.25W), composition (metal film), temperature coefficient (±100ppm/°C), operating temperature range (-65°C to 150°C), and physical dimensions (0.090" Dia x 0.250" L). The parts are mechanically and electrically interchangeable. The GSB14 variant offers improved reliability classification.

Q: What is the difference between the ±2% and ±1% tolerance options?

A: Tolerance specification defines the maximum allowable deviation of the actual resistance value from the nominal 20 kOhms specification. The RLR07C2002GPB14 and RLR07C2002GSB14 allow ±2% deviation (18.0 to 20.4 kOhms), while the RLR07C2002FSB14 allows ±1% deviation (19.8 to 20.2 kOhms). Selection depends on circuit precision requirements. Tighter tolerance does not affect power dissipation, temperature performance, or physical form factor.

Q: Are all substitute parts qualified to MIL-PRF-39017/01?

A: Yes. All three parts (RLR07C2002GPB14, RLR07C2002GSB14, and RLR07C2002FSB14) are manufactured to MIL-PRF-39017/01 specification and belong to the RLR07 military series. All parts feature moisture resistance and weldability as specified for military applications.

Q: Will substituting these parts require PCB redesign or re-qualification?

A: No. All substitute parts share identical axial package configuration and physical dimensions. No PCB layout modifications are required. Electrical parameters (resistance, power rating, temperature coefficient, operating temperature range) are maintained across all options, eliminating the need for circuit re-analysis or re-qualification.

Q: What does the failure rate classification indicate?

A: Failure rate classification (P or S) represents the expected failure rate per 1000 hours of operation under specified conditions. P (0.1%) indicates a higher failure rate, while S (0.001%) indicates a lower failure rate. The RLR07C2002GSB14 and RLR07C2002FSB14 both carry the S classification, representing superior reliability performance compared to the P classification of the RLR07C2002GPB14.
