Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the OPB910W55 are qualified based on electrical and mechanical parameter equivalence. All substitute candidates maintain identical specifications across the following critical parameters:

• Sensing distance: 0.375" (9.53mm)
• Sensing method: Through-Beam
• Output configuration: Totem Pole, Buffer
• Supply voltage: 4.75V ~ 5.25V
• Supply current: 15 mA
• Response time: 70ns
• Operating temperature range: -40°C ~ 85°C
• Package type: Module, Wire Leads
• Mounting type: Chassis Mount

The OPB910W55Z, OPB900W51Z, and OPB900W55Z all satisfy these electrical and mechanical requirements, making them direct functional equivalents. The primary distinction between these parts lies in product status and RoHS compliance classification.

Parameter Comparison

Engineering Selection Recommendations

For applications currently using the OPB910W55, the OPB910W55Z is the primary substitute. This part maintains the same base product number (OPB910) and provides direct functional equivalence with active product status and ROHS3 compliance.

The OPB900W51Z and OPB900W55Z are manufacturer-recommended alternatives based on the OPB900 base product number. Both parts are active products with ROHS3 compliance and identical electrical and mechanical specifications. These alternatives are suitable for new designs and applications where the OPB910 series is not required.

All three substitute parts offer improved compliance status compared to the obsolete OPB910W55, with ROHS3 certification and active manufacturing support.

Frequently Asked Questions (FAQ)

Q: Can OPB910W55Z directly replace OPB910W55 in existing designs?

A: Yes. The OPB910W55Z maintains identical electrical and mechanical specifications, including sensing distance, output configuration, supply voltage, current draw, response time, and operating temperature range. The primary difference is product status (active vs. obsolete) and RoHS compliance improvement.

Q: What is the difference between OPB910W55Z and OPB900W51Z?

A: Both parts are functionally equivalent with identical electrical and mechanical parameters. The distinction is the base product number: OPB910W55Z uses the OPB910 base, while OPB900W51Z uses the OPB900 base. Both are active products with ROHS3 compliance.

Q: Are the OPB900 series parts suitable for new designs?

A: Yes. The OPB900W51Z and OPB900W55Z meet all electrical and mechanical requirements for through-beam optical sensing at 0.375" (9.53mm) distance. Both are active products with current manufacturing support and ROHS3 compliance.

Q: Does packaging differ between these substitute parts?

A: All substitute parts are supplied in bulk packaging. The original OPB910W55 packaging specification was not provided in the technical data.

Q: Are there any compliance differences between the substitute options?

A: All three substitute parts (OPB910W55Z, OPB900W51Z, OPB900W55Z) are ROHS3 compliant and REACH unaffected. The original OPB910W55 is RoHS non-compliant, making any of the substitutes suitable for applications requiring RoHS compliance.
