Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 76PSB05 is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Circuit type (SPST), number of positions (5), current rating (150mA), and voltage rating (30VDC) must be identical.

Mechanical Parameters: Actuator type (piano), actuator level (raised), mounting configuration (through hole, right angle), pitch spacing (0.100"), and height above board (0.301") must match exactly.

Environmental Parameters: Operating temperature range (-40°C to 85°C), mechanical life (2,000 cycles), and electrical life (2,000 cycles) must be maintained.

Contact Specifications: Contact material (copper alloy) and contact finish (gold) must be preserved.

The 76PSB05T qualifies as a direct substitute based on complete alignment with all specified parameters.

Parameter Comparison

Engineering Selection Recommendations

The 76PSB05T is the direct substitute for the obsolete 76PSB05. Both components are manufactured by Grayhill Inc. within the same 76 series and maintain identical electrical, mechanical, and environmental specifications.

The primary distinction is product status: the 76PSB05 is obsolete, while the 76PSB05T is active production. The 76PSB05T additionally carries RoHS3 compliance, whereas the original 76PSB05 is RoHS non-compliant. Both maintain REACH unaffected status and EAR99 export classification.

For new designs or system replacements, the 76PSB05T is the appropriate selection. For legacy system repairs requiring exact form-fit-function compatibility, the 76PSB05T provides complete functional equivalence with the added benefit of current manufacturing support and regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can the 76PSB05T be used as a direct replacement for the 76PSB05 in existing assemblies?

A: Yes. The 76PSB05T provides complete electrical and mechanical equivalence. All critical parameters including circuit configuration, current and voltage ratings, actuator type, mounting configuration, and dimensional specifications are identical. The components are pin-compatible and functionally interchangeable.

Q: What is the difference between the 76PSB05 and 76PSB05T?

A: The primary differences are product status and regulatory compliance. The 76PSB05 is obsolete and RoHS non-compliant. The 76PSB05T is active production and RoHS3 compliant. All functional and electrical specifications remain identical.

Q: Are there packaging differences between these parts?

A: Yes. The 76PSB05 is supplied in standard packaging, while the 76PSB05T is supplied in tube packaging. This packaging difference does not affect component performance or compatibility.

Q: Does the RoHS3 compliance of the 76PSB05T affect compatibility?

A: No. RoHS3 compliance indicates the 76PSB05T meets current environmental regulations. This does not alter electrical performance or mechanical compatibility. The component functions identically to the non-compliant 76PSB05.

Q: What is the pitch specification and why is it important for substitution?

A: The pitch is 0.100" (2.54mm), representing the center-to-center spacing between switch positions. This specification must match exactly for proper PCB mounting and circuit board layout compatibility.

Q: Are the contact materials and finishes identical?

A: Yes. Both the 76PSB05 and 76PSB05T use copper alloy contacts with gold finish, ensuring consistent electrical performance and corrosion resistance.
