Key Parameters

Substitute Part Grouping Explanation

Substitution of the TSMP77000TR is determined by compatibility across the following critical parameters:

Mandatory Compatibility Criteria:

• Mounting Type: Surface Mount (required for PCB integration)
• Category: Optical Sensors (functional classification)
• Manufacturer: Vishay Semiconductor Opto Division (design lineage and support)
• Operating Temperature Range: −25°C to +85°C (environmental tolerance)
• RoHS3 Compliance: Required for regulatory alignment
• Voltage Supply Range: Overlap within 2.5V–5.5V envelope

Performance Parameters Subject to Variation:

• Sensing Distance: 5m (original specification; substitutes may differ)
• B.P.F. Center Frequency: 20–60kHz band (original specification; substitutes may differ)
• Current Supply: 700µA (original specification; substitutes may differ)
• Moisture Sensitivity Level: 4 (original specification; substitutes may differ)

The TSMP95000TR qualifies as a manufacturer-recommended substitute based on shared mounting technology, compliance certifications, and voltage supply compatibility, despite differences in sensing distance, center frequency, and power consumption characteristics.

Engineering Selection Recommendations

For TSMP77000TR Replacement:

The TSMP95000TR is the manufacturer-recommended substitute and is classified as Active product status, ensuring long-term availability and supply chain continuity. Both components maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for current manufacturing environments.

Key Considerations:

The TSMP95000TR operates at reduced power consumption (350µA versus 700µA), providing efficiency benefits in battery-powered applications. However, the sensing distance is reduced to 1.8m compared to the original 5m specification, and the center frequency is fixed at 45.0kHz rather than the 20–60kHz band. The substitute features improved moisture sensitivity (MSL 1 versus MSL 4), reducing handling and storage constraints.

Packaging differs between the main part (Cut Tape) and substitute (Tape & Reel), affecting procurement and assembly workflows. Orientation changes from Side View to Top View may require PCB layout verification to ensure optical path alignment with infrared signal sources.

Frequently Asked Questions (FAQ)

Q: Can TSMP95000TR directly replace TSMP77000TR in existing designs?

A: Direct replacement requires verification of three critical parameters: sensing distance tolerance (1.8m versus 5m), center frequency compatibility (45.0kHz fixed versus 20–60kHz band), and PCB layout accommodation for Top View orientation versus Side View. Electrical compatibility is confirmed through overlapping voltage supply ranges and surface mount technology.

Q: What are the compliance and regulatory implications of substitution?

A: Both components maintain ROHS3 compliance and REACH unaffected status. No regulatory barriers exist for substitution in markets requiring these certifications. Moisture sensitivity improvement (MSL 1 versus MSL 4) reduces handling and storage requirements.

Q: How do power consumption differences affect system design?

A: The TSMP95000TR consumes 350µA compared to 700µA for the TSMP77000TR, representing a 50% reduction. This benefits battery-powered remote control systems and reduces thermal load in continuous-operation applications. Supply voltage range compatibility (2V–5.5V for substitute versus 2.5V–5.5V for original) permits operation at lower minimum voltages.

Q: What packaging considerations apply to procurement and assembly?

A: The main part is supplied in Cut Tape (CT) packaging, while the substitute uses Tape & Reel (TR) format. Tape & Reel packaging is standard for high-volume automated assembly and offers improved handling efficiency. Cut Tape format is typically used for lower-volume or manual assembly operations.

Q: Does orientation change (Side View to Top View) require PCB redesign?

A: PCB layout verification is necessary to confirm that the Top View orientation of TSMP95000TR aligns with the infrared signal path in the application. Side View and Top View designations indicate different optical window positions relative to the component body. Mechanical clearance and signal reception geometry must be validated.

Q: Is the reduced sensing distance (1.8m versus 5m) a limiting factor?

A: Application-specific requirements determine whether 1.8m sensing distance is acceptable. Typical remote control applications operate within 2–3 meters, making the substitute suitable for most consumer electronics. Applications requiring extended range beyond 1.8m must retain the original TSMP77000TR or identify alternative components with greater sensing distance specifications.
