Substitute Part Grouping Explanation

Substitute parts for the RLR07C1503FSBSL23 are qualified based on strict parametric equivalence within the RLR07 military resistor series. The substitution criteria are:

• Identical resistance value: 150 kOhms
• Identical tolerance: ±1%
• Identical power rating: 0.25W (1/4W)
• Identical composition: Metal Film
• Identical package: Axial
• Identical temperature coefficient: ±100ppm/°C
• Identical operating temperature range: -65°C to 150°C
• Identical physical dimensions: 0.090" Dia x 0.250" L
• Identical military series compliance: MIL-PRF-39017/01, RLR07
• Identical failure rate classification: S (0.001%)

Substitute parts differ only in packaging configuration or manufacturing batch designation, which do not affect electrical or mechanical performance in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both RLR07C1503FSBSL23 and RLR07C1503FSB14 are active production parts manufactured by Vishay Dale within the military-grade RLR07 series. Selection between these parts is based on inventory availability and packaging batch designation. Both parts maintain identical electrical performance, mechanical compatibility, and compliance with MIL-PRF-39017/01 military specifications. RoHS non-compliance status is consistent across both parts. REACH and ECCN classifications are identical, ensuring equivalent regulatory treatment in procurement and supply chain applications.

Frequently Asked Questions (FAQ)

Q: Can RLR07C1503FSB14 be used as a direct replacement for RLR07C1503FSBSL23?

A: Yes. Both parts are parametrically equivalent with identical resistance, tolerance, power rating, temperature coefficient, operating temperature range, physical dimensions, and military series compliance. The difference in part number designation reflects packaging batch or configuration only and does not affect circuit performance.

Q: Are there any differences in reliability or failure rate between these parts?

A: No. Both parts carry identical failure rate classification S (0.001%) and are manufactured to the same MIL-PRF-39017/01 military specifications.

Q: What determines whether a part can substitute for RLR07C1503FSBSL23?

A: Substitution is determined by matching all electrical parameters (resistance value, tolerance, power rating, temperature coefficient), mechanical parameters (package type, physical dimensions, number of terminations), and series compliance (MIL-PRF-39017/01, RLR07). Any deviation in these parameters disqualifies a part from substitution.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both parts operate across the identical temperature range of -65°C to 150°C with the same temperature coefficient of ±100ppm/°C.

Q: What is the significance of the packaging designation difference in the part numbers?

A: The packaging designation (SL23 versus 14) indicates different manufacturing batch or packaging configuration. This does not affect electrical performance, mechanical fit, or circuit compatibility. Selection can be based on inventory availability.
