Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1-1622821-6 is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Resistance value: 47 mOhms (exact match required)
• Package / Case: 0805 (2012 Metric) (physical and electrical compatibility)
• Composition: Thick Film (electrical characteristics and performance profile)
• Features: Current Sense (application-specific requirement)
• Moisture Sensitivity Level: 1 (Unlimited) (handling and storage compatibility)

Allowable Variation Parameters:

• Tolerance: ±5% or tighter (±1% substitutes are functionally superior)
• Power Rating: 0.25W or higher (0.333W substitutes provide enhanced thermal margin)
• Temperature Coefficient: Variations within specified ranges
• Operating Temperature Range: -55°C ~ 125°C minimum (extended ranges are acceptable)
• Automotive Certification: AEC-Q200 qualification is an enhancement, not a requirement

All substitute parts listed maintain the mandatory parameters while offering improvements in tolerance, power rating, or automotive qualification status.

Parameter Comparison

Engineering Selection Recommendations

Direct Tolerance Match (±5%):

• ERJ-L06KJ47MV (Panasonic): Active product with identical tolerance specification. Panasonic ERJ-L06 series provides AEC-Q200 automotive qualification and ROHS3 compliance. Equivalent power rating (0.25W) and operating temperature range (-55°C ~ 125°C). Temperature coefficient improvement (±100ppm/°C vs. ±350ppm/°C) provides enhanced stability.
• UCR10EVHJSR047 (Rohm): Active product with identical tolerance specification. Rohm UCR series provides AEC-Q200 automotive qualification and ROHS3 compliance. Enhanced power rating (0.333W) and extended operating temperature range (-55°C ~ 155°C) provide superior thermal and environmental performance margins.

Improved Tolerance (±1%):

• ERJ-L06KF47MV (Panasonic): Active product with tighter tolerance specification (±1%). Panasonic ERJ-L06 series provides AEC-Q200 automotive qualification and ROHS3 compliance. Equivalent power rating (0.25W) and operating temperature range (-55°C ~ 125°C). Temperature coefficient improvement (±100ppm/°C) provides enhanced accuracy and stability.
• UCR10EVHFSR047 (Rohm): Active product with tighter tolerance specification (±1%). Rohm UCR series provides AEC-Q200 automotive qualification and ROHS3 compliance. Enhanced power rating (0.333W) and extended operating temperature range (-55°C ~ 155°C) provide superior thermal and environmental performance margins.

All substitute parts are active products with current manufacturing support, ROHS3 compliance, and AEC-Q200 automotive qualification, addressing the obsolescence status of the original component.

Frequently Asked Questions (FAQ)

Q: Can ERJ-L06KJ47MV directly replace 1-1622821-6 in existing designs?

A: Yes. ERJ-L06KJ47MV maintains identical resistance (47 mOhms), tolerance (±5%), power rating (0.25W), package (0805), and operating temperature range (-55°C ~ 125°C). The component is physically and electrically compatible. Panasonic ERJ-L06KJ47MV is an active product with AEC-Q200 qualification and ROHS3 compliance.

Q: What is the difference between the Panasonic and Rohm substitute options?

A: Both manufacturers provide functionally compatible substitutes. Panasonic ERJ-L06 series maintains the original 0.25W power rating and -55°C ~ 125°C temperature range. Rohm UCR series offers enhanced specifications with 0.333W power rating and extended -55°C ~ 155°C operating temperature range. Selection depends on thermal design requirements and temperature environment specifications.

Q: Should I select the ±1% tolerance variants over the ±5% variants?

A: Tolerance selection depends on circuit accuracy requirements. The ±1% variants (ERJ-L06KF47MV and UCR10EVHFSR047) provide tighter resistance specification and improved measurement accuracy in current sense applications. The ±5% variants (ERJ-L06KJ47MV and UCR10EVHJSR047) maintain the original tolerance specification. Both are functionally valid substitutes.

Q: Are all substitute parts qualified for automotive applications?

A: Yes. All four substitute parts carry AEC-Q200 automotive qualification. The original 1-1622821-6 does not specify automotive qualification. Automotive-qualified substitutes provide enhanced reliability documentation and qualification testing records suitable for automotive and industrial applications.

Q: Is the 0805 package dimension identical across all parts?

A: Yes. All parts use the 0805 (2012 Metric) package with identical footprint dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm). Physical board layout compatibility is maintained. Height variations (0.50mm to 0.70mm) are within standard PCB assembly tolerances and do not affect placement or soldering processes.

Q: What is the impact of temperature coefficient differences?

A: The original 1-1622821-6 specifies ±350ppm/°C temperature coefficient. Panasonic substitutes (ERJ-L06 series) provide ±100ppm/°C, and Rohm substitutes (UCR series) provide 0/+250ppm/°C. Lower temperature coefficients indicate improved resistance stability across the operating temperature range, beneficial for precision current sense applications.

Q: Can I use UCR10EVHJSR047 in place of 1-1622821-6 if my circuit operates above 125°C?

A: Yes. UCR10EVHJSR047 extends the operating temperature range to -55°C ~ 155°C, providing 30°C additional high-temperature margin. This is a direct functional upgrade for applications requiring extended temperature operation while maintaining all other electrical specifications.
