Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the OPB480N11Z are qualified based on the following critical parameters that determine functional equivalence:

• Sensing Distance: 0.125" (3.18mm) — all substitutes maintain identical sensing range
• Sensing Method: Through-Beam — all substitutes use identical detection principle
• Output Configuration: Pull-Up Resistor, Buffer — all substitutes provide identical signal output characteristics
• Voltage Supply Range: 4.5V ~ 16V — all substitutes operate within identical supply voltage window
• Current Supply: 7.5 mA — all substitutes draw identical supply current
• Response Time: 50ns — all substitutes maintain identical switching speed
• Operating Temperature Range: -40°C ~ 85°C — all substitutes support identical thermal operating window
• Series: Photologic® — all substitutes belong to the same product family
• RoHS & Compliance: ROHS3 Compliant, REACH Unaffected, EAR99 — all substitutes maintain identical regulatory status

Substitutes are grouped into two categories based on mounting configuration:

Category A - Chassis Mount Module (Wire Leads): OPB480T11Z, OPB490P11Z, OPB490T11Z — direct functional equivalents with identical mounting type and package configuration.

Category B - Through Hole PCB Mount: OPB460N11, OPB470N11 — functionally equivalent but require different mounting approach; suitable for applications where PCB-mounted configuration is acceptable.

Category C - Chassis Mount Module (Slot Configuration): OPB480L11Z — functionally equivalent with alternative slot-based mounting option.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain full electrical and mechanical compatibility with the OPB480N11Z across all specified parameters. Selection should be based on the following criteria:

For Direct Replacement (Chassis Mount, Wire Leads Configuration)

OPB480T11Z, OPB490P11Z, and OPB490T11Z are functionally identical to the OPB480N11Z with active product status. These parts require no design modification and provide the highest supply continuity. OPB490T11Z offers the largest available inventory (4186 Pcs), followed by OPB490P11Z (3665 Pcs) and OPB480T11Z (1100 Pcs).

For PCB-Mounted Applications

OPB460N11 and OPB470N11 are suitable substitutes when PCB-mounted through-hole configuration is acceptable. Both maintain identical electrical specifications and active product status. OPB460N11 provides higher inventory availability (2779 Pcs) compared to OPB470N11 (1910 Pcs).

For Alternative Chassis Mount Configuration

OPB480L11Z provides an alternative chassis mount option with slot-based configuration while maintaining all electrical parameters. This part is active with 1028 Pcs inventory.

All substitute parts are ROHS3 Compliant, REACH Unaffected, and classified under ECCN EAR99, maintaining identical regulatory compliance with the original OPB480N11Z.

Frequently Asked Questions (FAQ)

Q: Can OPB460N11 or OPB470N11 be used as direct replacements for OPB480N11Z?

A: These parts are electrically equivalent but differ in mounting type. OPB460N11 and OPB470N11 are through-hole PCB mount components, while OPB480N11Z is chassis mount with wire leads. Substitution requires design modification to accommodate the different mounting approach. Both maintain identical sensing distance, output configuration, voltage/current specifications, and response time.

Q: What is the difference between OPB480T11Z and OPB490T11Z?

A: Both parts are functionally identical in all electrical and mechanical parameters. The primary difference is the base product number designation (OPB480 vs. OPB490). Both are active products with identical specifications and can be used interchangeably. OPB490T11Z has higher inventory availability.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts listed (OPB460N11, OPB470N11, OPB480L11Z, OPB480T11Z, OPB490P11Z, OPB490T11Z) are ROHS3 Compliant and REACH Unaffected, maintaining identical regulatory status with the original OPB480N11Z.

Q: What is the key parameter that determines substitution eligibility?

A: The critical parameters are sensing distance (0.125" / 3.18mm), sensing method (through-beam), output configuration (pull-up resistor with buffer), and electrical specifications (4.5V-16V supply, 7.5mA current, 50ns response time). All listed substitutes maintain these parameters identically.

Q: Can I use OPB480L11Z as a replacement for OPB480N11Z?

A: Yes. OPB480L11Z is functionally equivalent with identical electrical specifications and active product status. The difference is the slot-based mounting configuration versus the wire lead configuration of OPB480N11Z. Both are chassis mount components suitable for equivalent applications.

Q: Why is OPB480N11Z marked as obsolete?

A: The OPB480N11Z is classified as obsolete, which is why equivalent active substitutes are provided. All listed substitute parts maintain full functional equivalence while offering active product status and improved supply availability.
