Substitute Part Grouping Explanation

Substitution for the RLR20C2001GSRSL is determined by strict equivalence across the following critical parameters:

• Resistance value: 2 kOhms
• Tolerance: ±2%
• Power rating: 0.5W
• Composition: Metal Film
• Package: Axial
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -65°C to 150°C
• Physical dimensions: 0.138" Dia x 0.375" L
• Military series compliance: MIL-PRF-39017/02, RLR20
• Failure rate classification: S (0.001%)

The identified substitute part RLR20C2001GSB14 meets all these parameters identically, differing only in manufacturing batch designation (GSB14 versus GSRSL).

Parameter Comparison

Engineering Selection Recommendations

Both RLR20C2001GSRSL and RLR20C2001GSB14 are active production parts from Vishay Dale with identical electrical and mechanical specifications. Selection between these parts should be based on inventory availability and procurement lead times. Both parts are RoHS non-compliant and REACH affected, with identical ECCN (EAR99) and HTSUS (8533.21.0090) classifications. The RLR20C2001GSB14 currently has higher inventory availability (1153 units versus 1119 units), which may influence procurement decisions for high-volume applications.

Frequently Asked Questions (FAQ)

Q: Can RLR20C2001GSB14 be used as a direct replacement for RLR20C2001GSRSL?

A: Yes. Both parts are electrically and mechanically identical, with matching resistance, tolerance, power rating, temperature coefficient, operating range, and physical dimensions. The difference is limited to manufacturing batch designation.

Q: What determines if a part is a valid substitute?

A: A valid substitute must match all critical parameters: 2 kOhms resistance, ±2% tolerance, 0.5W power rating, metal film composition, axial package, ±100ppm/°C temperature coefficient, -65°C to 150°C operating range, and 0.138" Dia x 0.375" L dimensions.

Q: Are there any compliance differences between these parts?

A: No. Both parts share identical RoHS status (non-compliant), REACH status (affected), ECCN classification (EAR99), and HTSUS code (8533.21.0090).

Q: What is the failure rate significance?

A: Both parts are rated at failure rate class S (0.001%), indicating military-grade reliability suitable for critical applications.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes. Identical axial package dimensions and lead configurations ensure direct interchangeability in through-hole PCB designs without layout modifications.
