Substitute Part Grouping Explanation

Substitution of the obsolete OPB720A-30VZ is based on the following critical parameters that must remain consistent:

  • Sensing Method: Reflective optical sensing technology
  • Sensing Object: Kodak® Paper and white paper detection capability
  • Output Configuration: NPN open collector output
  • Sensing Distance Range: 0.040" to 30.000" (1mm to 762mm)
  • Package Type: Module form factor
  • Compliance Standards: ROHS3 Compliant, REACH Unaffected

The OPB720B-30VZ qualifies as a direct substitute based on matching all functional sensing parameters, detection range, output type, and regulatory compliance. The primary distinction lies in the supply voltage specification and active product status, which enables continued procurement and technical support.

Engineering Selection Recommendations

The OPB720B-30VZ is the active equivalent for the obsolete OPB720A-30VZ. Both sensors maintain identical sensing distance ranges, reflective detection methodology, and NPN open collector output configuration. Both parts satisfy ROHS3 compliance and REACH regulatory requirements.

The primary design consideration is the supply voltage specification: the OPB720A-30VZ operates at 10V to 30V, while the OPB720B-30VZ operates at 4V to 7V. Circuit designs utilizing the OPB720A-30VZ must be evaluated to determine voltage compatibility with the substitute part. If the existing design requires the higher voltage range of the OPB720A-30VZ, alternative solutions within the OPB720 series should be assessed. The OPB720B-30VZ is recommended for new designs and ongoing production where the 4V to 7V supply voltage range is compatible with system requirements.

Frequently Asked Questions (FAQ)

Q: Can the OPB720B-30VZ directly replace the OPB720A-30VZ in existing designs?

A: The OPB720B-30VZ provides functional equivalence in sensing distance, detection method, and output configuration. However, the supply voltage range differs: OPB720A-30VZ requires 10V to 30V, while OPB720B-30VZ operates at 4V to 7V. Circuit compatibility must be verified before substitution.

Q: What is the primary reason for substituting the OPB720A-30VZ?

A: The OPB720A-30VZ is classified as obsolete. The OPB720B-30VZ is an active product with ongoing manufacturer support, inventory availability, and technical documentation.

Q: Are both parts packaged identically?

A: Both the OPB720A-30VZ and OPB720B-30VZ are supplied in module form factor packaging. The OPB720A-30VZ packaging type is unspecified in available documentation, while the OPB720B-30VZ is supplied in bulk packaging.

Q: Do both sensors detect the same materials?

A: Yes. Both the OPB720A-30VZ and OPB720B-30VZ are designed to detect Kodak® Paper and white paper surfaces across the identical sensing distance range of 0.040" to 30.000" (1mm to 762mm).

Q: Are there regulatory compliance differences between these parts?

A: No. Both parts are ROHS3 compliant and REACH unaffected, with identical moisture sensitivity levels (MSL 1 - Unlimited).
