Substitute Part Grouping Explanation

Substitute parts for the RLR20C1002FMB14 are qualified based on identical electrical and mechanical parameters within the RLR20 military resistor series. The substitution criteria are:

• Resistance value: 10 kOhms
• Tolerance: ±1%
• Power rating: 0.5W (1/2W)
• Composition: Metal Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -65°C to 150°C
• Package: Axial
• Physical dimensions: 0.138" Dia × 0.375" L (4.61mm × 9.53mm)
• Series compliance: MIL-PRF-39017/02, RLR20
• Features: Military, Moisture Resistant, Weldable

The identified substitutes (RLR20C1002FRB14 and RLR20C1002FSB14) meet all these parameters. Differences exist only in failure rate classifications, which reflect manufacturing process variations within the same product family.

Parameter Comparison

Engineering Selection Recommendations

All three parts—RLR20C1002FMB14, RLR20C1002FRB14, and RLR20C1002FSB14—are active products from Vishay Dale with identical electrical and mechanical specifications. Selection between them is determined by failure rate requirements:

• RLR20C1002FMB14: Failure rate M (1%) — standard military grade
• RLR20C1002FRB14: Failure rate R (0.01%) — enhanced reliability
• RLR20C1002FSB14: Failure rate S (0.001%) — highest reliability

All parts comply with MIL-PRF-39017/02 military specifications, feature moisture resistance and weldability, and are suitable for applications requiring -65°C to 150°C operation. RoHS non-compliance and REACH-affected status are consistent across all variants. Selection should be based on application reliability requirements and inventory availability.

Frequently Asked Questions (FAQ)

Q: Can RLR20C1002FRB14 or RLR20C1002FSB14 be used as direct replacements for RLR20C1002FMB14?

A: Yes. All three parts share identical resistance (10 kOhms), tolerance (±1%), power rating (0.5W), composition (metal film), temperature coefficient (±100ppm/°C), operating temperature range (-65°C to 150°C), and axial package dimensions (0.138" Dia × 0.375" L). They are interchangeable from an electrical and mechanical standpoint.

Q: What is the difference between the three part numbers?

A: The only difference is the failure rate classification. RLR20C1002FMB14 has failure rate M (1%), RLR20C1002FRB14 has failure rate R (0.01%), and RLR20C1002FSB14 has failure rate S (0.001%). All other specifications are identical.

Q: Which part should I select for high-reliability applications?

A: Selection depends on application requirements. RLR20C1002FSB14 offers the lowest failure rate (0.001%), followed by RLR20C1002FRB14 (0.01%), and RLR20C1002FMB14 (1%). All are military-grade and suitable for demanding environments.

Q: Are these parts RoHS compliant?

A: No. All three parts are RoHS non-compliant. They are REACH-affected and classified under ECCN EAR99.

Q: Can these resistors be used in applications requiring weldability?

A: Yes. All three parts feature weldable construction as part of their military specification design.

Q: What is the physical footprint compatibility?

A: All three parts have identical axial package dimensions of 0.138" diameter by 0.375" length (4.61mm × 9.53mm), ensuring direct board-level compatibility.
