Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RLR05C1001GSB14 are classified based on the following allowed parameters:

Direct Equivalent (Same Specifications):

• RLR05C1001GRB14: Identical electrical specifications (1 kOhms ±2%, 0.125W) with equivalent failure rate classification (R, 0.01%) and all military features preserved.

Upgrade Options (Enhanced Tolerance):

• RLR05C1001FRB14: Tighter tolerance specification (±1% vs. ±2%) with improved failure rate (R, 0.01%), maintaining all other electrical and mechanical parameters.
• RLR05C1001FSB14: Tighter tolerance specification (±1% vs. ±2%) with superior failure rate (S, 0.001%), representing the highest reliability option in this group.

All substitute parts maintain identical resistance value, power rating, package type, temperature coefficient, operating temperature range, and military series classification. Substitution is permitted where the application tolerance and reliability requirements align with the specified parameters.

Parameter Comparison

Engineering Selection Recommendations

Selection among RLR05C1001GSB14 and its substitutes is determined by tolerance and reliability requirements:

RLR05C1001GSB14 (Primary Part): Select when ±2% tolerance meets circuit specifications and failure rate S (0.001%) is required. This part maintains the original design specification.

RLR05C1001GRB14 (Direct Equivalent): Select as a direct replacement when ±2% tolerance is acceptable and failure rate R (0.01%) satisfies reliability requirements. Identical electrical performance with higher inventory availability (1206 units).

RLR05C1001FRB14 (Tolerance Upgrade): Select when circuit design permits ±1% tolerance and failure rate R (0.01%) is acceptable. Provides improved tolerance performance over the primary part.

RLR05C1001FSB14 (Tolerance & Reliability Upgrade): Select when ±1% tolerance is required and failure rate S (0.001%) is specified. This part offers the tightest tolerance with the highest reliability classification, matching the primary part's failure rate.

All parts comply with MIL-PRF-39017/05 military specifications, feature moisture-resistant and weldable construction, and operate across the full -65°C to 150°C temperature range. RoHS non-compliance and REACH-affected status are consistent across all options.

Frequently Asked Questions (FAQ)

Q: Can RLR05C1001GRB14 replace RLR05C1001GSB14 in all applications?

A: RLR05C1001GRB14 is a direct equivalent with identical tolerance (±2%) and electrical specifications. The difference is failure rate classification (R vs. S). Substitution is valid where failure rate R (0.01%) meets application requirements. Verify reliability specifications before substitution.

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

A: RLR05C1001FRB14 and RLR05C1001FSB14 provide ±1% tolerance compared to ±2% for the primary part and RLR05C1001GRB14. Tighter tolerance reduces resistor value variation and improves circuit accuracy. Select ±1% parts only when circuit design requires this specification.

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

A: Yes. All parts listed—RLR05C1001GSB14, RLR05C1001GRB14, RLR05C1001FRB14, and RLR05C1001FSB14—use identical axial package construction with 0.066" diameter and 0.150" length (1.68mm x 3.81mm). Direct mechanical substitution is supported.

Q: What does failure rate classification mean?

A: Failure rate S (0.001%) and R (0.01%) indicate predicted failure rates per MIL-PRF-39017/05. S-rated parts have lower predicted failure rates than R-rated parts. Select based on application reliability requirements and mission-critical specifications.

Q: Can I use RLR05C1001FSB14 as a drop-in replacement for RLR05C1001GSB14?

A: Yes. RLR05C1001FSB14 is mechanically and electrically compatible with identical package, resistance, power rating, and temperature range. It offers improved tolerance (±1% vs. ±2%) and equivalent failure rate (S, 0.001%). This represents an upgrade path with no compatibility concerns.

Q: Are there any compliance differences between these parts?

A: All parts share identical compliance status: RoHS non-compliant, REACH-affected, ECCN EAR99, and HTSUS 8533.21.0090. No compliance differences exist among the substitute options.
