Substitute Part Grouping Explanation

Substitution eligibility for the RLR07C3003GMB14 is determined by strict equivalence across the following parameters:

• Resistance value: 300 kOhms
• Tolerance: ±2%
• Power rating: 0.25W
• 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
• Military qualification: MIL-PRF-39017/01, RLR07 series
• Features: Military, Moisture Resistant, Weldable

The RLR07C3003GSB14 meets all these criteria and is classified as a direct substitute. Differences in failure rate classification (M vs. S) do not affect functional substitutability but reflect manufacturing process variations within the same military specification.

Parameter Comparison

Engineering Selection Recommendations

Both the RLR07C3003GMB14 and RLR07C3003GSB14 are active products from Vishay Dale with identical electrical and mechanical specifications. Selection between these parts should be based on:

• Failure rate classification: RLR07C3003GSB14 carries a superior failure rate (S: 0.001%) compared to RLR07C3003GMB14 (M: 1%), indicating tighter manufacturing controls
• Compliance requirements: Both parts maintain identical RoHS non-compliant and REACH Affected status, suitable for military applications where these standards do not apply

Frequently Asked Questions (FAQ)

Q: Can RLR07C3003GSB14 replace RLR07C3003GMB14 in existing designs?

A: Yes. Both parts are electrically and mechanically identical with matching resistance, tolerance, power rating, temperature coefficient, operating range, and axial package dimensions. They are qualified to the same MIL-PRF-39017/01 specification.

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

A: Failure rate M (1%) and S (0.001%) represent different manufacturing process controls within the same military specification. The S classification indicates a more stringent production process. Both are valid substitutes for the same application.

Q: Are the physical dimensions identical?

A: Yes. Both parts measure 0.090" diameter by 0.250" length (2.29mm x 6.35mm), ensuring identical PCB layout compatibility and mounting requirements.

Q: Do both parts meet the same military specifications?

A: Yes. Both RLR07C3003GMB14 and RLR07C3003GSB14 are qualified to MIL-PRF-39017/01 and belong to the RLR07 military series with identical moisture resistance and weldability features.

Q: Are there any compliance differences between these parts?

A: No. Both parts share identical RoHS non-compliant and REACH Affected status, making them suitable for the same regulatory environments.
