Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RLR05C1001GSBSL are classified based on the following allowed parameters:

Direct Equivalent (Same Specifications):

• RLR05C1001GRB14: Identical electrical specifications (1 kOhms ±2%, 0.125W) with matching mechanical dimensions, package type, and operating temperature range. Differs only in failure rate classification (R vs. S) and inventory availability.

Upgraded Performance (Enhanced Tolerance):

• RLR05C1001FRB14: Maintains 1 kOhms resistance and 0.125W power rating with improved tolerance of ±1% (versus ±2%). Identical mechanical package, operating temperature, and military series compliance.
• RLR05C1001FSB14: Maintains 1 kOhms resistance and 0.125W power rating with improved tolerance of ±1% (versus ±2%). Identical mechanical package, operating temperature, and military series compliance.

All substitute parts share the same base product number (RLR05), composition (metal film), temperature coefficient (±100ppm/°C), operating range (-65°C to 150°C), axial package configuration, and military-grade construction features.

Parameter Comparison

Engineering Selection Recommendations

Selection among RLR05C1001GSBSL and its substitutes is determined by tolerance requirements and failure rate specifications:

RLR05C1001GSBSL (Primary Specification): Use when ±2% tolerance meets circuit requirements and S-class failure rate (0.001%) is mandated by design specifications or military procurement standards.

RLR05C1001GRB14 (Direct Equivalent): Use as a direct substitute when ±2% tolerance is acceptable and R-class failure rate (0.01%) satisfies application requirements. Provides higher inventory availability (1206 units).

RLR05C1001FRB14 (Upgraded Tolerance): Use when circuit design requires improved tolerance of ±1% and R-class failure rate is acceptable. Suitable for precision applications where tighter resistance values enhance performance.

RLR05C1001FSB14 (Upgraded Tolerance): Use when circuit design requires improved tolerance of ±1% and S-class failure rate (0.001%) is required. Combines enhanced tolerance with superior reliability classification.

All parts maintain identical mechanical compatibility, electrical characteristics (except tolerance), military-grade construction, and compliance status. Selection is based on tolerance specification and failure rate classification appropriate to the application.

Frequently Asked Questions (FAQ)

Q: Can RLR05C1001GRB14 be used as a direct replacement for RLR05C1001GSBSL?

A: Yes. Both parts share identical resistance (1 kOhms), tolerance (±2%), power rating (0.125W), mechanical dimensions (0.066" Dia x 0.150" L), package type (axial), and operating temperature range (-65°C to 150°C). The difference in failure rate classification (R vs. S) does not affect electrical or mechanical compatibility.

Q: What is the advantage of using RLR05C1001FRB14 or RLR05C1001FSB14?

A: Both parts provide improved tolerance of ±1% compared to the ±2% tolerance of the primary part. This tighter tolerance specification is beneficial for precision circuits where resistance value accuracy directly impacts performance. All other electrical and mechanical parameters remain identical.

Q: Are all substitute parts in the same axial package?

A: Yes. All parts listed—RLR05C1001GSBSL, RLR05C1001GRB14, RLR05C1001FRB14, and RLR05C1001FSB14—use identical axial through-hole packaging with dimensions of 0.066" Dia x 0.150" L (1.68mm x 3.81mm). They are mechanically interchangeable on PCBs designed for axial resistor mounting.

Q: What does the failure rate classification mean?

A: Failure rate classification indicates the expected reliability level. S-class (0.001%) represents superior reliability, while R-class (0.01%) represents standard military-grade reliability. Selection depends on application criticality and procurement specifications.

Q: Do all parts comply with the same military standard?

A: Yes. All substitute parts are manufactured to MIL-PRF-39017/05 military specification and belong to the RLR05 series. They share identical military-grade construction features including moisture resistance and weldability.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, provided the circuit design tolerates the specified tolerance and failure rate of the selected substitute. RLR05C1001GRB14 is a direct equivalent. RLR05C1001FRB14 and RLR05C1001FSB14 offer improved tolerance and may enhance circuit performance in precision applications.
