Substitute Part Grouping Explanation

Substitution eligibility for the RLR07C3322FPB14 is determined by strict equivalence across the following critical parameters:

• Resistance value: 33.2 kOhms
• Tolerance: ±1%
• Power rating: 0.25W (1/4W)
• Composition: Metal Film
• Package: Axial
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -65°C to 150°C
• Physical dimensions: 0.090" Dia x 0.250" L
• Series classification: RLR07 Military per MIL-PRF-39017/01
• Features: Military, Moisture Resistant, Weldable

The RLR07C3322FSB14 qualifies as a direct substitute based on identical electrical specifications and mechanical compatibility. The distinction between these parts lies in failure rate classification: the primary part carries a P-level failure rate (0.1%), while the substitute carries an S-level failure rate (0.001%), representing improved reliability characteristics within the same component family.

Parameter Comparison

Engineering Selection Recommendations

Both the RLR07C3322FPB14 and RLR07C3322FSB14 maintain active product status and identical compliance classifications (RoHS non-compliant, REACH Affected, EAR99 export control). Selection between these parts is based on failure rate requirements: applications requiring standard reliability specifications utilize the P-level part (RLR07C3322FPB14), while applications demanding enhanced reliability performance select the S-level part (RLR07C3322FSB14). Both parts satisfy military-grade MIL-PRF-39017/01 specifications and are suitable for direct substitution in circuit designs where the specified resistance, tolerance, power rating, and environmental operating range are required.

Frequently Asked Questions (FAQ)

Q: Can RLR07C3322FSB14 be used as a direct replacement for RLR07C3322FPB14?

A: Yes. Both parts share identical electrical specifications (33.2 kOhms ±1%, 0.25W metal film), mechanical dimensions (0.090" Dia x 0.250" L axial package), and environmental ratings (-65°C to 150°C). The substitute part carries an improved failure rate specification (S-level vs. P-level) and is electrically and mechanically interchangeable.

Q: What is the difference between P-level and S-level failure rates?

A: Failure rate classification indicates expected component reliability under specified conditions. P-level (0.1%) and S-level (0.001%) represent different reliability grades within the RLR07 military series. S-level components meet more stringent reliability requirements and are suitable for applications demanding enhanced performance margins.

Q: Are both parts suitable for military and aerospace applications?

A: Yes. Both RLR07C3322FPB14 and RLR07C3322FSB14 are manufactured to MIL-PRF-39017/01 military specifications and feature moisture-resistant, weldable construction. Both maintain identical military-grade certifications and environmental operating ranges.

Q: What are the physical installation considerations for these axial resistors?

A: Both parts are identical in physical dimensions (0.090" Dia x 0.250" L / 2.29mm x 6.35mm) and axial package configuration. Installation procedures, PCB layout, and lead spacing requirements are identical between the two parts.

Q: Are there any compliance differences between these substitute parts?

A: No. Both parts carry identical compliance status: RoHS non-compliant, REACH Affected, and EAR99 export classification. Regulatory and environmental compliance considerations are equivalent.
