Substitute Part Grouping Explanation

Substitution eligibility for the RLR05C2003FSB14 is determined by strict equivalence across the following parameters:

• Resistance Value: 200 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power Rating: 0.125W / 1/8W (exact match required)
• Composition: Metal Film (exact match required)
• Temperature Coefficient: ±100ppm/°C (exact match required)
• Operating Temperature Range: -65°C to 150°C (exact match required)
• Package Type: Axial (exact match required)
• Physical Dimensions: 0.066" Dia × 0.150" L / 1.68mm × 3.81mm (exact match required)
• Series: RLR05, MIL-PRF-39017/05 (exact match required)
• Features: Military, Moisture Resistant, Weldable (exact match required)

All substitute parts listed below meet these criteria. Variations in failure rate classification and packaging designations do not affect functional equivalence for standard circuit applications.

Engineering Selection Recommendations

All substitute parts listed are manufactured by Vishay Dale within the RLR05 military-grade resistor series and maintain full electrical and mechanical equivalence to the RLR05C2003FSB14. Selection among available substitutes should be based on the following criteria:

Product Status: The RLR05C2003FSB14 is discontinued. All listed substitutes are active products with current manufacturing and distribution availability.

Failure Rate Classification: Substitute parts are available across three failure rate categories:

• S-Class (0.001%): RLR05C2003FSB1419, RLR05C2003FSBSL, RLR05C2003FSBSL19, RLR05C2003FSM23 — Equivalent to the original part's failure rate specification
• R-Class (0.01%): RLR05C2003FRB14 — Lower failure rate for enhanced reliability applications
• P-Class (0.1%): RLR05C2003FPB14 — Standard military-grade failure rate

Compliance and Certifications: All parts share identical RoHS non-compliance status, REACH-affected classification, EAR99 ECCN designation, and HTSUS code 8533.21.0090.

Inventory Availability: Current stock levels range from 700 to 1038 pieces across substitute options, ensuring supply continuity.

Frequently Asked Questions (FAQ)

Q: Can RLR05C2003FPB14 be used as a direct replacement for RLR05C2003FSB14?

A: Yes. The RLR05C2003FPB14 is a direct functional equivalent with identical electrical specifications (200 kΩ, ±1%, 0.125W, metal film, ±100ppm/°C, -65°C to 150°C operating range) and mechanical package (axial, 0.066" × 0.150"). The difference is the failure rate classification (P-class 0.1% versus S-class 0.001%), which does not affect circuit performance in standard applications.

Q: What is the difference between RLR05C2003FSB14 and RLR05C2003FRB14?

A: Both parts are electrically and mechanically identical 200 kΩ ±1% 1/8W axial metal film resistors. The primary distinction is the failure rate: RLR05C2003FSB14 carries an S-class (0.001%) rating, while RLR05C2003FRB14 carries an R-class (0.01%) rating. RLR05C2003FRB14 is currently active and available, whereas RLR05C2003FSB14 is discontinued.

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

A: Yes. All substitute parts use the identical axial package with dimensions of 0.066" diameter × 0.150" length (1.68mm × 3.81mm). They are mechanically interchangeable in PCB layouts and through-hole applications designed for the original RLR05C2003FSB14.

Q: Do the substitute parts meet military specifications?

A: Yes. All substitute parts conform to MIL-PRF-39017/05 specifications and are classified as military-grade resistors. They retain the moisture resistance and weldability features of the original part.

Q: What is the significance of the different packaging designations (FSB, FPB, FRB, FSBSL, FSM)?

A: The packaging designations indicate different manufacturing or distribution batches and failure rate classifications within the RLR05 series. All designated parts maintain identical electrical and mechanical specifications. The designations do not affect functional performance in circuit applications.

Q: Can I substitute RLR05C2003FSM23 for RLR05C2003FSB14 in a high-reliability application?

A: Yes. RLR05C2003FSM23 is electrically and mechanically equivalent with the same S-class (0.001%) failure rate as the original RLR05C2003FSB14. Both parts are suitable for high-reliability military and aerospace applications.

Q: Is there a difference in temperature performance between substitute parts?

A: No. All substitute parts operate across the identical temperature range of -65°C to 150°C with the same temperature coefficient of ±100ppm/°C. Temperature performance is equivalent across all listed substitutes.
