Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HOA6970-T55 are identified based on strict equivalence across the following critical parameters:

Functional Equivalence Criteria:

• Sensing distance: 0.125" (3.18mm)
• Sensing method: Through-Beam
• Output configuration: Totem Pole, Buffer
• Mounting type: Through Hole
• Supply current: 15 mA
• Response time: 70ns
• Operating temperature range: -40°C ~ 70°C
• Package type: PCB Mount

The substitute parts OPB970N11 and OPB970T55, both manufactured by TT Electronics/Optek Technology, satisfy all functional and mechanical requirements. Both parts operate within compatible voltage ranges (4.75V ~ 5.25V), which fall within the operational envelope of the original HOA6970-T55 (4.5V ~ 7V). Both substitute parts maintain active product status and carry enhanced compliance certifications (ROHS3 Compliant, REACH Unaffected).

Parameter Comparison

Engineering Selection Recommendations

OPB970N11 and OPB970T55 Suitability:

Both OPB970N11 and OPB970T55 are suitable direct substitutes for the obsolete HOA6970-T55. The selection between these two substitute parts depends on packaging and inventory requirements rather than functional differences.

Compliance Advantages:

The substitute parts carry ROHS3 Compliant certification and REACH Unaffected status, representing enhanced environmental and regulatory compliance compared to the original RoHS Compliant designation of the HOA6970-T55. Both substitute parts maintain active product status, ensuring long-term availability and supply chain stability.

Voltage Specification Consideration:

The substitute parts operate within a narrower voltage range (4.75V ~ 5.25V) compared to the HOA6970-T55 (4.5V ~ 7V). This narrower range is compatible with standard 5V supply systems and falls within the operational envelope of the original part. Applications requiring operation at the extreme limits of the original 4.5V or 7V specifications require circuit-level verification.

Electrical and Mechanical Compatibility:

All critical electrical parameters—supply current (15 mA), response time (70ns), output configuration (Totem Pole, Buffer), and operating temperature range (-40°C ~ 70°C)—are identical across all three parts. Through-hole PCB mounting is consistent across all variants, ensuring mechanical compatibility with existing PCB layouts.

Frequently Asked Questions (FAQ)

Q: Can OPB970N11 and OPB970T55 be used interchangeably with HOA6970-T55?

A: Yes. Both parts satisfy all functional and mechanical requirements. The primary difference is packaging format (Bulk for both substitutes). Electrical performance, sensing distance, output configuration, and mounting type are identical.

Q: What is the difference between OPB970N11 and OPB970T55?

A: Both parts are functionally equivalent with identical electrical specifications and performance characteristics. The designation difference reflects packaging or temperature grade variants within the OPB970 base product line. Selection between these two should be based on packaging requirements and inventory availability.

Q: Does the narrower voltage range of the substitute parts affect compatibility?

A: The substitute parts operate at 4.75V ~ 5.25V, which is compatible with standard 5V supply systems. This range falls within the operational envelope of the original HOA6970-T55 (4.5V ~ 7V). Applications operating at the extreme limits (below 4.75V or above 5.25V) require circuit-level verification to confirm compatibility.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both OPB970N11 and OPB970T55 carry ROHS3 Compliant certification and REACH Unaffected status, representing enhanced environmental compliance compared to the original part's RoHS Compliant designation.

Q: Will the substitute parts fit existing PCB layouts designed for HOA6970-T55?

A: Yes. Both substitute parts use identical through-hole PCB mount packaging. Mechanical compatibility with existing PCB layouts is maintained.

Q: What is the product status of the substitute parts?

A: Both OPB970N11 and OPB970T55 are classified as Active products, ensuring ongoing availability and supply chain support. This contrasts with the obsolete status of the HOA6970-T55.

Q: Are there any performance differences in response time or sensing distance?

A: No. All three parts maintain identical response time (70ns) and sensing distance (0.125" / 3.18mm) specifications.
