Frequently Asked Questions (FAQ)

Q: Can RLR07C5621FSB14 be used as a direct replacement for RLR07C5621FSM22?

A: Yes. Both parts are parametric equivalents with identical resistance value, tolerance, power rating, temperature coefficient, operating temperature range, physical dimensions, and military specification compliance. Direct substitution is electrically and mechanically compatible.

Q: Are there differences in the part numbers that affect functionality?

A: The part numbers differ only in their suffix designations (FSM22 versus FSB14). These designations reflect manufacturing lot or packaging variations within the same RLR07 series, but do not affect electrical performance or mechanical compatibility.

Q: What is the significance of the RLR07 series designation?

A: RLR07 identifies the base product family within Vishay Dale's military resistor line, indicating compliance with MIL-PRF-39017/01 specification. All parts within this series share the same core electrical and mechanical characteristics.

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

A: Both parts meet military specification MIL-PRF-39017/01 and carry failure rate classification S (0.001%), making them suitable for military and high-reliability applications. However, specific application requirements and qualification standards should be verified against your system specifications.

Q: What is the difference between the packaging designations in the part numbers?

A: The packaging designation (FSM22 versus FSB14) indicates different packaging configurations or manufacturing batches within the same electrical specification. Both are supplied in bulk packaging and maintain identical component specifications.
