Key Parameters

Substitute Part Grouping Explanation

Substitution for the RLR07C1503GSBSL is determined by the following critical parameters:

• Resistance Value: Must be 150 kOhms
• Power Rating: Must be 0.25W (1/4W)
• Package Type: Must be Axial
• Physical Dimensions: Must be 0.090" Dia x 0.250" L (2.29mm x 6.35mm)
• Series Compliance: Must conform to MIL-PRF-39017/01 RLR07 series
• Composition: Must be Metal Film
• Temperature Coefficient: Must be ±100ppm/°C
• Operating Temperature Range: Must be -65°C to 150°C

The identified substitute parts RLR07C1503FRB14 and RLR07C1503FSB14 meet all these critical parameters. The primary difference is an upgrade in tolerance specification from ±2% to ±1%, which represents improved accuracy without affecting electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

All three parts—RLR07C1503GSBSL, RLR07C1503FRB14, and RLR07C1503FSB14—are active products manufactured by Vishay Dale and comply with MIL-PRF-39017/01 military specifications.
