Substitute Part Grouping Explanation

Substitution eligibility for the RLR07C1504FMB14 is determined by strict equivalence across the following critical parameters:

• Resistance value: 1.5 MOhms
• 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 compliance: MIL-PRF-39017/01, RLR07 base product

The RLR07C1504FSB14 meets all electrical and mechanical equivalence criteria and is classified as a direct substitute. Differences in failure rate classification do not affect functional interchangeability within the specified parameter envelope.

Parameter Comparison

Frequently Asked Questions (FAQ)

Q: Can RLR07C1504FSB14 be used as a direct replacement for RLR07C1504FMB14?

A: Yes. Both parts are electrically and mechanically equivalent across all specified parameters including resistance value, tolerance, power rating, temperature coefficient, operating temperature range, and physical dimensions. Both comply with MIL-PRF-39017/01 specifications.

Q: What is the difference between the M and S failure rate classifications?

A: The M-class (1%) and S-class (0.001%) designations indicate different failure rate levels under MIL-PRF-39017/01 standards. The S-class represents superior reliability performance. This difference does not affect functional interchangeability in circuit applications.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts have identical axial package dimensions of 0.090" diameter by 0.250" length (2.29mm x 6.35mm), ensuring identical PCB footprint and mounting compatibility.

Q: Do both parts meet the same military specifications?

A: Yes. Both RLR07C1504FMB14 and RLR07C1504FSB14 are manufactured to MIL-PRF-39017/01 specifications and belong to the RLR07 military resistor series with identical feature sets including moisture resistance and weldability.

Q: What are the regulatory compliance considerations?

A: Both parts carry identical regulatory status: RoHS non-compliant, REACH Affected, and EAR99 export classification. No compliance advantage exists between the two parts.
