Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RPI-1040 is determined by matching the following critical electrical and mechanical parameters:

• Operating Angle: ±90° (4-direction detection capability)
• Output Type: NPN (signal output configuration)
• Mounting Type: Surface Mount (PCB assembly compatibility)
• Operating Temperature Range: -25°C ~ 85°C (thermal operating window)
• Voltage - Supply: 5V (power supply requirement)
• Current - Output: 30mA (load capacity)
• Package / Case: 6-SMD form factor (physical footprint and pin configuration)

The RPI-1035 meets all specified electrical and mechanical parameters required for functional equivalence with the RPI-1040.

Parameter Comparison

Engineering Selection Recommendations

The RPI-1035 is a direct functional equivalent to the RPI-1040 based on matching electrical specifications and mechanical compatibility. Both components are manufactured by Rohm Semiconductor and maintain identical performance parameters across all critical operating conditions.

Both parts carry obsolete product status, indicating limited future availability. The RPI-1035 currently maintains higher inventory levels (8,650 Pcs) compared to the RPI-1040 (3,742 Pcs), providing improved procurement accessibility.

Regulatory compliance is equivalent between both parts: ROHS3 Compliant and REACH Unaffected status applies to both the RPI-1040 and RPI-1035.

The primary distinction between these components is the Moisture Sensitivity Level (MSL): the RPI-1040 specifies MSL 4 (72 Hours), while the RPI-1035 specifies MSL 1 (Unlimited). This difference reflects handling and storage requirements but does not affect functional performance in deployed applications.

Frequently Asked Questions (FAQ)

Q: Can the RPI-1035 directly replace the RPI-1040 in existing designs?

A: Yes. The RPI-1035 matches all critical electrical parameters (5V supply, 30mA output, NPN configuration, ±90° detection angle) and operating temperature range (-25°C ~ 85°C). Both components use compatible 6-SMD surface mount packaging suitable for standard PCB assembly processes.

Q: What is the difference between the package designations "6-SMD, No Lead" and "6-SMD Module"?

A: Both designations refer to 6-pin surface mount packages with compatible physical footprints and pin configurations. The terminology variation reflects different manufacturer documentation conventions but does not indicate functional or mechanical incompatibility.

Q: Why do the RPI-1040 and RPI-1035 have different Moisture Sensitivity Levels?

A: MSL ratings specify maximum exposure time to moisture before component degradation risk increases. The RPI-1040 (MSL 4, 72 Hours) requires more controlled storage conditions than the RPI-1035 (MSL 1, Unlimited). This difference affects component handling and storage protocols but does not impact electrical performance or field reliability in sealed applications.

Q: Are both parts suitable for the same operating temperature applications?

A: Yes. Both the RPI-1040 and RPI-1035 operate across the identical temperature range of -25°C to 85°C, ensuring equivalent thermal performance in all specified environmental conditions.

Q: What compliance certifications apply to both substitute parts?

A: Both components are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution.
