Substitute Part Grouping Explanation

Substitution of the OPB982P11 is determined by strict equivalence across the following parameters: sensing distance (0.125" / 3.18mm), sensing method (through-beam), output configuration (totem pole, inverted), mounting type (chassis mount), supply current (15 mA), supply voltage range (4.75V ~ 5.25V), response time (70ns), operating temperature range (-40°C ~ 70°C), and package type (module with wire leads).

All substitute parts listed maintain these specifications without deviation. The primary distinction between the main part and substitutes is product status: OPB982P11 is obsolete, while all listed alternatives are active products. Secondary distinctions include packaging format (bulk vs. standard) and RoHS compliance status (OPB982P11 is non-compliant; all substitutes are ROHS3 compliant).

Engineering Selection Recommendations

All listed substitute parts are functionally equivalent to OPB982P11 across all specified electrical and mechanical parameters. The primary advantage of substitution is transition from obsolete to active product status, ensuring long-term supply availability and manufacturing continuity.

All substitute parts are ROHS3 compliant, whereas OPB982P11 is RoHS non-compliant. This compliance upgrade aligns with current regulatory requirements for electronic component procurement in regulated industries.

Selection among substitute parts should be based on inventory availability and packaging requirements. OPB992P51Z offers the highest inventory level (69,800 pcs), followed by OPB992N55Z (20,299 pcs), providing optimal supply security for high-volume applications. OPB982P11Z represents the closest direct replacement, maintaining the OPB982 base product number while upgrading to active status and ROHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can OPB982P11 be directly replaced with any of the listed substitutes?

A: Yes. All listed parts maintain identical specifications for sensing distance, sensing method, output configuration, supply voltage, supply current, response time, operating temperature range, and package type. Direct circuit substitution is supported without modification.

Q: What is the difference between OPB982P11 and OPB982P11Z?

A: Both parts share identical electrical and mechanical specifications. The primary differences are product status (OPB982P11 is obsolete; OPB982P11Z is active) and RoHS compliance (OPB982P11 is non-compliant; OPB982P11Z is ROHS3 compliant). OPB982P11Z is the recommended direct replacement.

Q: Are there differences between OPB982, OPB932, and OPB992 base product families?

A: All parts within these families maintain the specified electrical and mechanical parameters for this application. Differences exist in internal design variants indicated by the suffix codes (P, W, T, L, N), but these do not affect the parameters that determine substitution eligibility.

Q: What packaging format should be selected?

A: All substitute parts are supplied in bulk packaging with wire leads, matching the original OPB982P11 module configuration. Packaging format does not affect electrical or mechanical compatibility.

Q: Is RoHS compliance mandatory for substitution?

A: RoHS compliance is determined by application requirements and regulatory jurisdiction. All substitute parts are ROHS3 compliant, providing compliance flexibility for applications subject to RoHS directives. OPB982P11 non-compliance may restrict use in regulated environments.
