Engineering Selection Recommendations

The OPB882N55Z is obsolete and requires substitution. Three active equivalent parts are available:

OPB882T55Z is manufacturer-recommended and maintains all electrical specifications. The primary difference is mounting type (Chassis Mount vs. Free Hanging). This part is suitable for applications where chassis mounting is compatible with the system design.

OPB880N11Z and OPB880N55Z are parametric equivalents with identical electrical characteristics and Free Hanging mounting type matching the original part. Both parts are active and ROHS3 compliant. OPB880N11Z offers 1329 units in stock, while OPB880N55Z offers 945 units in stock, providing supply continuity.

Selection between these three substitutes depends on mounting requirements. For Free Hanging applications, OPB880N11Z or OPB880N55Z provide direct form-factor compatibility. For Chassis Mount applications, OPB882T55Z is the appropriate selection. All three parts satisfy regulatory compliance requirements (ROHS3 Compliant, REACH Unaffected).

Frequently Asked Questions (FAQ)

Q: Can OPB882T55Z replace OPB882N55Z directly?

A: OPB882T55Z is electrically and functionally equivalent. The difference is mounting type: OPB882T55Z uses Chassis Mount while OPB882N55Z uses Free Hanging. Compatibility depends on your system's mounting configuration.

Q: What is the difference between OPB880N11Z and OPB880N55Z?

A: Both parts are parametric equivalents with identical electrical specifications and Free Hanging mounting. The difference is in the base product number designation (OPB880 vs. OPB882), but all critical parameters remain equivalent. Both are suitable substitutes for the obsolete OPB882N55Z.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. OPB882T55Z, OPB880N11Z, and OPB880N55Z are all ROHS3 Compliant and REACH Unaffected, matching the compliance status of the original OPB882N55Z.

Q: Which substitute has the best stock availability?

A: OPB880N11Z has the highest inventory with 1329 units in stock, followed by OPB880N55Z with 945 units, and OPB882T55Z with 760 units.

Q: Can I use OPB882T55Z in a Free Hanging application?

A: OPB882T55Z is designed for Chassis Mount applications. For Free Hanging mounting, use OPB880N11Z or OPB880N55Z to maintain form-factor compatibility.
