OPB882N55 Equivalent & Substitute Parts

Part Overview

The OPB882N55 is an optical sensor through-beam phototransistor module manufactured by TT Electronics/Optek Technology. This component features a 0.125" (3.18mm) sensing distance with through-beam detection methodology and unamplified phototransistor output configuration. The OPB882N55 is classified as obsolete product status. Identifying equivalent and substitute parts is necessary to maintain design continuity and ensure component availability for new production runs and field replacements.

Substitute Part Grouping Explanation

Substitute parts for the OPB882N55 are qualified based on electrical and mechanical parameter equivalence within the optical sensor through-beam phototransistor module category. The critical parameters determining substitution eligibility are:

Sensing Distance: 0.125" (3.18mm)
Sensing Method: Through-Beam
Output Configuration: Phototransistor
Current - DC Forward (If) (Max): 50 mA
Current - Collector (Ic) (Max): 30 mA
Voltage - Collector Emitter Breakdown (Max): 30 V
Operating Temperature: -40°C ~ 85°C
Package / Case: Module, Pre-Wired
Type: Unamplified

All identified substitute parts maintain these core electrical and mechanical specifications. Variations in mounting type (Free Hanging versus Chassis Mount) and product status (Active versus Obsolete) are noted but do not disqualify substitution eligibility when electrical parameters remain equivalent.

Engineering Selection Recommendations

OPB882T55Z is designated as the manufacturer-recommended substitute for OPB882N55. This part maintains full electrical parameter equivalence and is currently in active product status with ROHS3 compliance. The primary design consideration is mounting type: OPB882T55Z uses Chassis Mount configuration versus the Free Hanging mount of the original OPB882N55. This difference requires mechanical design review for integration compatibility.

OPB880N11Z and OPB880N55Z are parametric equivalents offering identical electrical specifications and operating characteristics. Both parts are active products with ROHS3 compliance. OPB880N11Z and OPB880N55Z retain Free Hanging mounting type, matching the original OPB882N55 mechanical interface. Selection between OPB880N11Z and OPB880N55Z depends on specific application requirements not differentiated by the provided electrical parameters.

All substitute parts provide improved regulatory compliance through ROHS3 certification compared to the non-compliant original part. Component availability is confirmed across all substitute options with active inventory status.

Frequently Asked Questions (FAQ)

Q: Can OPB882T55Z directly replace OPB882N55 without mechanical redesign?

A: OPB882T55Z maintains full electrical equivalence but differs in mounting type (Chassis Mount versus Free Hanging). Mechanical integration compatibility must be evaluated based on your specific application design.

Q: What is the difference between OPB880N11Z and OPB880N55Z?

A: Both parts are parametric equivalents with identical electrical specifications, operating temperature range, and sensing characteristics. The designation difference reflects internal product line variations within the OPB880 base product family. Selection should be based on application-specific requirements and availability.

Q: Is the RoHS compliance difference between OPB882N55 and substitute parts significant?

A: The original OPB882N55 is RoHS non-compliant while all substitute parts are ROHS3 compliant. For applications subject to RoHS regulatory requirements or customer specifications mandating RoHS compliance, substitute parts are necessary.

Q: Are all substitute parts available in the same packaging format?

A: OPB882N55 packaging is not specified in the provided data. All substitute parts are available in Bulk packaging. Confirm packaging requirements for your procurement process.

Q: Can I use OPB880N55Z as a substitute if my design requires Free Hanging mounting?

A: Yes. OPB880N55Z provides Free Hanging mounting type matching the original OPB882N55 configuration while maintaining all electrical parameter equivalence and offering active product status with ROHS3 compliance.
