Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 76PSB02 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Requirements:

• Circuit configuration must be SPST
• Current rating must be 150mA minimum
• Voltage rating must be 30VDC minimum
• Contact material and finish must match (Copper Alloy, Gold-plated)

Mechanical Compatibility Requirements:

• Number of positions: 2
• Actuator type: Piano with raised level
• Mounting type: Through Hole, Right Angle
• Pitch: 0.100" (2.54mm)
• Height above board: 0.301" (7.65mm)

Environmental Compatibility Requirements:

• Operating temperature range: -40°C to 85°C minimum
• Mechanical and electrical life: 2,000 cycles minimum

The 76PSB02T qualifies as a direct substitute based on identical electrical, mechanical, and environmental specifications. The primary distinction is product status and packaging configuration.

Parameter Comparison

Engineering Selection Recommendations

For New Designs and Procurement:

The 76PSB02T is the appropriate selection for all applications currently specified for the 76PSB02. The substitute part maintains complete electrical and mechanical equivalence while offering the advantage of active product status from the manufacturer. The 76PSB02T is ROHS3 compliant, meeting current regulatory requirements for electronic components in regulated markets.

For Existing Inventory Management:

The 76PSB02 remains functionally suitable for applications already in production or field deployment where RoHS compliance is not a contractual requirement. However, transition to the 76PSB02T is recommended for long-term supply chain stability, as the original part number is classified as obsolete.

Compliance Considerations:

The 76PSB02T's ROHS3 compliance status provides regulatory advantage for applications subject to RoHS directives. Both parts maintain identical REACH and ECCN classifications (REACH Unaffected, EAR99), with no additional compliance burden associated with substitution.

Frequently Asked Questions (FAQ)

Q: Can the 76PSB02T be used as a direct replacement for the 76PSB02 in existing circuit designs?

A: Yes. The 76PSB02T is electrically and mechanically identical to the 76PSB02 across all functional parameters: SPST circuit, 150mA current rating, 30VDC voltage rating, piano actuator configuration, through-hole right-angle mounting, and 0.100" pitch. No circuit modifications are required.

Q: What is the primary reason for substituting the 76PSB02 with the 76PSB02T?

A: The 76PSB02 is classified as obsolete, creating long-term procurement risk. The 76PSB02T is an active product from the same manufacturer with identical specifications, ensuring continued availability and supply chain continuity.

Q: Are there packaging differences between these parts?

A: Yes. The 76PSB02 is supplied in bulk packaging, while the 76PSB02T is supplied in tube packaging. This difference does not affect electrical or mechanical performance and may provide handling and storage advantages depending on application requirements.

Q: Does the RoHS compliance difference affect functional compatibility?

A: No. RoHS compliance is a regulatory and material composition attribute, not a functional performance characteristic. Both parts operate identically within the specified electrical and environmental parameters. The 76PSB02T's ROHS3 compliance is advantageous for applications subject to RoHS directives.

Q: Are the contact materials and finishes identical?

A: Yes. Both parts feature copper alloy contacts with gold plating, ensuring equivalent electrical performance, contact resistance, and reliability characteristics.

Q: What is the mechanical life expectancy for both parts?

A: Both the 76PSB02 and 76PSB02T are rated for 2,000 mechanical cycles and 2,000 electrical cycles, providing identical operational durability.

Q: Can these parts be used in temperature-sensitive applications?

A: Yes. Both parts are rated for operation across the -40°C to 85°C temperature range, suitable for industrial and commercial applications with standard environmental requirements.
