Substitute Part Grouping Explanation
Substitution of the 32205108 is determined by strict equivalence across the following critical parameters:
Primary Substitution Criteria:
- Resistance value at 0°C: 100 Ohms
- RTD material composition: Platinum (Pt)
- Temperature coefficient: 3850ppm/°C
- Resistance tolerance: ±0.3%
- Operating temperature range: -196°C ~ 400°C
- Accuracy specification: ±0.3°C
- Termination type: Wire Leads
- Mounting configuration: Free Hanging

Engineering Selection Recommendations
The 20009700-00 serves as the direct equivalent substitute for the obsolete 32205108. Both components are manufactured by TE Connectivity Measurement Specialties and maintain identical electrical and mechanical specifications across all critical parameters: 100 Ohms resistance at 0°C, platinum RTD material, 3850ppm/°C temperature coefficient, ±0.3% tolerance, and ±0.3°C accuracy.
The primary distinction between these parts is product status: the 32205108 is classified as obsolete while the 20009700-00 maintains active production status. This transition from obsolete to active status ensures continued availability and supply chain reliability for applications requiring RTD temperature measurement in the -196°C to 400°C operating range.
Both components satisfy ROHS3 compliance requirements. The 20009700-00 is supplied in bulk packaging, which may require adjustment to procurement and inventory management procedures compared to the original part's packaging configuration.
Frequently Asked Questions (FAQ)
Q: What makes the 20009700-00 a valid substitute for the 32205108?
A: The 20009700-00 maintains electrical and mechanical equivalence across all critical parameters: identical 100 Ohms resistance at 0°C, platinum RTD material, 3850ppm/°C temperature coefficient, ±0.3% resistance tolerance, ±0.3°C accuracy, wire lead termination, free hanging mounting, and cylindrical glass probe package. Both components are manufactured by TE Connectivity Measurement Specialties.
Q: Why is substitution necessary for the 32205108?
A: The 32205108 is classified as obsolete, indicating discontinued production. The 20009700-00 is an active production equivalent that provides functional and electrical compatibility while ensuring ongoing supply availability.
Q: Are there differences in packaging between these parts?
A: The 32205108 packaging configuration is not specified in available data. The 20009700-00 is supplied in bulk packaging. Procurement processes should account for this packaging difference when transitioning between components.
Q: Will the 20009700-00 operate across the same temperature range as the 32205108?
A: Both components operate across the -196°C to 400°C temperature range with identical accuracy specifications of ±0.3°C.
Q: Are both components RoHS compliant?
A: The 32205108 is confirmed ROHS3 compliant. RoHS compliance status for the 20009700-00 is not specified in available technical data.
Q: What is the resistance tolerance specification for the 20009700-00?
A: The 20009700-00 maintains the same ±0.3% resistance tolerance at 0°C as the 32205108.
