Substitute Part Grouping Explanation

Substitution eligibility for the RLR05C9533FPRSL is determined by strict equivalence across the following parameters:

• Resistance value: 953 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.125W / 1/8W (exact match required)
• Composition: Metal Film (exact match required)
• Package type: Axial (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -65°C to 150°C (exact match required)
• Series: RLR05 military series (exact match required)
• Features: Military, Moisture Resistant, Weldable (exact match required)
• Physical dimensions: 0.066" Dia x 0.150" L (exact match required)

The RLR05C9533FRRSL qualifies as a direct substitute based on identical electrical and mechanical parameters. The primary distinction is packaging format: the main part uses standard packaging, while the substitute is supplied in Tape & Reel (TR) format. Both parts maintain full compliance with MIL-PRF-39017/05 specifications.

Parameter Comparison

Engineering Selection Recommendations

The RLR05C9533FRRSL is a direct functional equivalent to the RLR05C9533FPRSL. Both components meet identical electrical specifications and are certified to MIL-PRF-39017/05 military standards. The substitute part is currently active in production, whereas the main part is discontinued.

Selection between these parts should be based on procurement requirements:

• For applications requiring standard packaging, the RLR05C9533FPRSL remains available through existing inventory channels.
• For new procurement or high-volume applications, the RLR05C9533FRRSL in Tape & Reel format offers active production status and improved failure rate classification (R vs. P).

Both parts share identical RoHS non-compliance and REACH-affected status. No compliance differences exist between the two options. Physical dimensions, electrical performance, and environmental operating ranges are identical, ensuring direct interchangeability in circuit applications.

Frequently Asked Questions (FAQ)

Q: Can RLR05C9533FRRSL replace RLR05C9533FPRSL in existing designs?

A: Yes. Both parts are electrically and mechanically identical. The substitute differs only in packaging format (Tape & Reel vs. standard packaging). Circuit performance and reliability are equivalent.

Q: What is the difference between the packaging formats?

A: RLR05C9533FPRSL uses standard packaging suitable for individual component handling. RLR05C9533FRRSL is supplied in Tape & Reel (TR) format, optimized for automated assembly processes and high-volume production.

Q: Are there compliance differences between these parts?

A: No. Both parts share identical RoHS non-compliance and REACH-affected status. Military certification (MIL-PRF-39017/05) applies to both.

Q: Why does the substitute have a lower failure rate?

A: The failure rate difference (R at 0.01% vs. P at 0.1%) reflects current production quality metrics. Both parts meet military specifications. The lower failure rate on the active part reflects ongoing manufacturing improvements.

Q: Can I use these parts interchangeably on PCBs?

A: Yes, for through-hole assembly. Both parts have identical axial package dimensions (0.066" Dia x 0.150" L) and two terminations. Mechanical fit and electrical performance are identical.

Q: Which part should I specify for new designs?

A: Specify RLR05C9533FRRSL. This part is active in production, whereas RLR05C9533FPRSL is discontinued. Active production status ensures long-term availability and supply chain stability.
