RLR05C1000FSM23 Equivalent & Substitute Parts

Part Overview

The RLR05C1000FSM23 is a 100 Ohm, ±1% tolerance, 1/8W (0.125W) through-hole axial resistor manufactured by Vishay Dale. This metal film resistor is designed for military applications per MIL-PRF-39017/05 specification and features moisture-resistant, weldable construction. The component is currently in active production status with 1022 units available in stock. Substitute parts are identified when inventory constraints, lead time requirements, or procurement preferences necessitate alternative sourcing while maintaining identical electrical and mechanical performance.

Substitute Part Grouping Explanation

The RLR05C1000FSB14 is classified as a parametric equivalent to the RLR05C1000FSM23. Substitution eligibility is determined by strict matching of the following critical parameters:

• Resistance value: 100 Ohms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• 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 (1.68mm x 3.81mm)
• Number of terminations: 2
• Military series compliance: MIL-PRF-39017/05, RLR05 base product

Both parts share identical electrical specifications and mechanical form factors, enabling direct substitution in circuit applications without design modification.

Parameter Comparison

Engineering Selection Recommendations

Both the RLR05C1000FSM23 and RLR05C1000FSB14 are active production components from Vishay Dale with identical electrical and mechanical specifications. Selection between these parts should be based on inventory availability and procurement lead times. The RLR05C1000FSB14 currently maintains higher stock levels (1471 units versus 1022 units), which may provide supply chain advantages for high-volume applications. Both components maintain RoHS non-compliant status and REACH-affected classification, with identical ECCN (EAR99) and HTSUS (8533.21.0090) designations. Military-grade construction, moisture resistance, and weldable terminations are preserved across both part numbers.

Frequently Asked Questions (FAQ)

Q: Can RLR05C1000FSB14 be used as a direct replacement for RLR05C1000FSM23?

A: Yes. Both parts are parametric equivalents with identical resistance (100 Ohms), tolerance (±1%), power rating (0.125W), temperature coefficient (±100ppm/°C), operating temperature range (-65°C to 150°C), and axial package dimensions (0.066" Dia x 0.150" L). Direct substitution is permissible without circuit redesign.

Q: Are there any differences in military compliance between these parts?

A: No. Both components comply with MIL-PRF-39017/05 specification and belong to the RLR05 military series. Failure rate classification (S, 0.001%) is identical for both parts.

Q: What is the significance of the different part number suffixes (FSM23 vs. FSB14)?

A: The suffix variations indicate different manufacturing batches or procurement lot designations within the same base product (RLR05C1000F). The electrical and mechanical specifications remain unchanged across these designations.

Q: Are moisture-resistant and weldable properties maintained in both parts?

A: Yes. Both RLR05C1000FSM23 and RLR05C1000FSB14 feature moisture-resistant, weldable metal film construction suitable for military and harsh environment applications.

Q: What compliance certifications apply to both parts?

A: Both components are RoHS non-compliant and REACH-affected. ECCN classification is EAR99 for both parts, with HTSUS code 8533.21.0090.
