Key Parameters

Substitute Part Grouping Explanation

Substitution of the ERA-S33J102V is evaluated based on the following critical parameters:

• Resistance Value: 1 kOhms (exact match required)
• Mounting Type: Surface Mount (SMD/SMT)
• Temperature Coefficient: Nominal range 3300ppm/°C to 3850ppm/°C (acceptable variance for temperature correction applications)
• Operating Temperature Range: Minimum -40°C to 125°C coverage
• Tolerance: ±5% or better
• Compliance: RoHS and REACH status alignment

The substitute part 32207615 (Yageo Nexensos) meets these criteria as an RTD (Resistance Temperature Detector) with platinum sensing element, 1 kOhms nominal resistance, superior tolerance (±0.12%), and compatible temperature coefficient (3850ppm/°C). Both components are surface-mount devices with RoHS compliance and MSL 1 rating.

Parameter Comparison

Engineering Selection Recommendations

The ERA-S33J102V is obsolete, necessitating substitution for new designs or ongoing production support. The 32207615 from Yageo Nexensos is an active product that satisfies the core electrical requirements: identical 1 kOhms resistance, compatible temperature coefficient within acceptable variance, and extended operating temperature range (-50°C to 130°C versus -40°C to 125°C). The substitute offers superior tolerance (±0.12% versus ±5%), which provides enhanced accuracy in temperature correction applications.

Both components maintain RoHS compliance and unlimited moisture sensitivity level (MSL 1), ensuring regulatory and environmental compatibility. The 32207615 is packaged in 0805 (2012 Metric) form factor with SMD termination, maintaining surface-mount compatibility with the original design. Active product status of the substitute ensures long-term availability and supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can the 32207615 directly replace the ERA-S33J102V in existing designs?

A: Yes, for temperature correction circuit applications. Both components share identical 1 kOhms resistance, surface-mount configuration, and compatible temperature coefficients (3300ppm/°C versus 3850ppm/°C). The substitute operates across an extended temperature range and provides superior tolerance, making it functionally equivalent or superior in most applications.

Q: What is the difference between the metal film resistor and RTD technologies?

A: The ERA-S33J102V is a metal film temperature-sensitive resistor with a temperature coefficient of 3300ppm/°C. The 32207615 is an RTD (Resistance Temperature Detector) using platinum sensing element with a temperature coefficient of 3850ppm/°C. Both exhibit predictable resistance change with temperature and are suitable for temperature correction circuits. The RTD offers higher accuracy (±0.3°C) compared to the metal film resistor tolerance specification.

Q: Are there package compatibility concerns?

A: Both components are surface-mount devices. The ERA-S33J102V uses the ERAS series package, while the 32207615 uses the 0805 (2012 Metric) package. PCB footprint compatibility must be verified during design transition, as package dimensions may differ despite both being surface-mount form factors.

Q: What compliance certifications apply to both parts?

A: Both the ERA-S33J102V and 32207615 are RoHS compliant and REACH unaffected. Both carry MSL 1 (unlimited) moisture sensitivity ratings, indicating no special moisture handling requirements during storage or assembly.

Q: Why is the substitute part's temperature coefficient slightly higher?

A: The 32207615 has a temperature coefficient of 3850ppm/°C compared to the ERA-S33J102V at 3300ppm/°C. This 550ppm/°C difference is within acceptable variance for temperature correction applications and reflects the platinum RTD technology used in the substitute. The higher accuracy tolerance (±0.12% versus ±5%) compensates for this coefficient variance in precision applications.
