Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1-1622821-3 is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Resistance value: 22 mOhms
• Package / Case: 0805 (2012 Metric)
• Features: Current Sense capability
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation Parameters:

• Tolerance: ±5% or tighter (±1%)
• Power Rating: 0.25W (1/4W) or higher (0.333W / 1/3W)
• Composition: Thick Film or Metal Foil
• Operating Temperature Range: -55°C ~ 125°C or extended range
• Temperature Coefficient: Values within specified ranges

Substitute parts are grouped into two categories based on composition and power rating enhancements while maintaining the core electrical and mechanical specifications required for current sense applications in 0805 package format.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Same Tolerance and Power Rating):

CSR0805JT22L0 from Stackpole Electronics is the direct equivalent substitute. This part maintains the ±5% tolerance and 0.25W power rating of the original component while offering active product status and ROHS3 compliance. The extended operating temperature range (-55°C ~ 155°C) and improved temperature coefficient (±200ppm/°C) provide enhanced performance margins. This substitute is suitable for direct replacement in existing designs without circuit modification.

Enhanced Performance Substitutes (Improved Tolerance and/or Power Rating):

PF0805FRF7W0R022L from YAGEO provides tighter tolerance (±1%) and metal foil composition with moisture resistance features. This part maintains the 0.25W power rating while offering superior temperature stability (±100ppm/°C) and extended operating range. Metal foil construction provides enhanced reliability for precision current sensing applications.

UCR10EVHJSR022 and UCR10EVHFSR022 from Rohm Semiconductor offer increased power rating (0.333W / 1/3W) with automotive AEC-Q200 qualification. UCR10EVHJSR022 maintains ±5% tolerance matching the original specification, while UCR10EVHFSR022 provides ±1% tolerance. Both parts are suitable for applications requiring automotive-grade reliability and higher thermal dissipation capability.

All substitute parts maintain ROHS3 compliance, unlimited moisture sensitivity rating (MSL 1), and current sense functionality required for the original application.

Frequently Asked Questions (FAQ)

Q: Can CSR0805JT22L0 be used as a direct replacement for 1-1622821-3?

A: Yes. CSR0805JT22L0 maintains identical resistance (22 mOhms), tolerance (±5%), power rating (0.25W), package (0805), and current sense features. The part is electrically and mechanically compatible for direct substitution.

Q: What is the difference between the Stackpole and YAGEO substitutes?

A: CSR0805JT22L0 (Stackpole) uses thick film composition and maintains ±5% tolerance. PF0805FRF7W0R022L (YAGEO) uses metal foil composition with tighter ±1% tolerance and lower temperature coefficient (±100ppm/°C). Both maintain 0.25W power rating and 0805 package. Metal foil construction in the YAGEO part provides superior temperature stability and moisture resistance.

Q: Why do the Rohm parts have higher power ratings?

A: UCR10EVHJSR022 and UCR10EVHFSR022 are rated at 0.333W (1/3W) compared to the original 0.25W (1/4W). Higher power rating indicates greater thermal dissipation capability. These parts are suitable for applications with higher current or thermal stress while maintaining the same 0805 package footprint.

Q: Are the Rohm parts suitable for automotive applications?

A: Yes. UCR10EVHJSR022 and UCR10EVHFSR022 carry AEC-Q200 automotive qualification. These parts are suitable for automotive current sense applications requiring automotive-grade reliability standards.

Q: What is the significance of the extended operating temperature range in substitute parts?

A: Substitute parts offer -55°C ~ 155°C operating range compared to the original -55°C ~ 125°C. Extended upper temperature limit provides additional thermal margin for applications operating at elevated ambient or self-heating conditions.

Q: Can I use a ±1% tolerance part in place of the ±5% original?

A: Yes. Tighter tolerance (±1%) is a compatible upgrade. PF0805FRF7W0R022L and UCR10EVHFSR022 provide ±1% tolerance, which is more stringent than the original ±5% specification and suitable for precision current sensing applications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All four substitute parts (CSR0805JT22L0, PF0805FRF7W0R022L, UCR10EVHJSR022, and UCR10EVHFSR022) are ROHS3 compliant, meeting environmental and regulatory requirements.

Q: What is the difference in temperature coefficient between parts?

A: Temperature coefficient indicates resistance change with temperature. The original part has ±350ppm/°C. Substitutes range from ±100ppm/°C (YAGEO metal foil) to ±200ppm/°C (Stackpole) to 0/+250ppm/°C (Rohm). Lower temperature coefficient indicates better stability across temperature variations.

Q: Can I use these parts interchangeably on the same PCB?

A: Yes. All substitute parts maintain identical 0805 (2012 Metric) package dimensions and footprint. Physical placement and soldering procedures remain unchanged. Electrical performance differences are determined by tolerance, composition, and temperature coefficient specifications.
