Key Parameters

Substitute Part Grouping Explanation

Substitution analysis for the PS1195WB-TR is based on the following critical parameters that define functional equivalence:

Primary Substitution Criteria:

• Wavelength specification (880nm infrared detection)
• Optical sensor category classification
• Surface mount packaging technology
• Electrical ratings (voltage, current, power dissipation)
• Operating temperature range compatibility
• Regulatory compliance (RoHS, REACH)

Analysis of Provided Substitute:

The TPS1195WB-TR, also manufactured by Stanley Electric Co, is classified as an LED Indication component in the discrete semiconductor category. This part does not satisfy the primary substitution criteria for the PS1195WB-TR. The TPS1195WB-TR is a light-emitting device, whereas the PS1195WB-TR is a light-detecting phototransistor. These represent fundamentally different functional categories within optical semiconductors and cannot serve as direct equivalents based on the provided specifications.

Parameter Comparison

Engineering Selection Recommendations

Based on the provided technical specifications and product data:

PS1195WB-TR Status: The PS1195WB-TR is classified as obsolete. The component maintains full RoHS compliance and REACH unaffected status, with current inventory of 804 pieces available.

TPS1195WB-TR Assessment: While the TPS1195WB-TR shares the same manufacturer and maintains equivalent regulatory compliance (ROHS3 Compliant, REACH Unaffected), it does not function as a substitute for the PS1195WB-TR. The TPS1195WB-TR is an LED indication device, not an optical sensor. The functional categories are distinct: one detects infrared radiation at 880nm, while the other emits visible light for indication purposes.

Recommendation: Direct substitution of TPS1195WB-TR for PS1195WB-TR is not supported by the provided specifications. Alternative phototransistor components with matching 880nm wavelength, 2-SMD surface mount packaging, and equivalent electrical ratings must be sourced from the component database.

Frequently Asked Questions (FAQ)

Q: Can the TPS1195WB-TR replace the PS1195WB-TR in my circuit?

A: No. The TPS1195WB-TR is an LED indication component, not an optical sensor. The PS1195WB-TR is a phototransistor designed to detect 880nm infrared radiation. These components serve opposite functions and are not interchangeable.

Q: What makes two optical components substitutable?

A: Substitution requires matching in the following areas: wavelength specification, sensor type (phototransistor vs. photodiode), electrical ratings (voltage and current limits), package type, and mounting orientation. The PS1195WB-TR and TPS1195WB-TR differ in component category and function.

Q: Is the PS1195WB-TR still available?

A: The PS1195WB-TR is classified as obsolete but has current inventory of 804 pieces available. For long-term procurement, equivalent phototransistor components with 880nm wavelength and 2-SMD surface mount packaging should be identified.

Q: Are there regulatory compliance differences between these parts?

A: Both components maintain EAR99 ECCN classification and REACH unaffected status. The PS1195WB-TR is RoHS Compliant, while the TPS1195WB-TR is ROHS3 Compliant. Both meet current regulatory requirements for their respective applications.

Q: What is the significance of the 2-SMD, No Lead package?

A: This package designation indicates a surface mount configuration with two leads and no through-hole connections. Package compatibility is a substitution requirement, but package alone does not determine functional equivalence. The component's optical and electrical characteristics must also match.
