Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 76PSB03 is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Circuit type (SPST), number of positions (3), current rating (150mA), and voltage rating (30VDC) must be identical.

Mechanical Parameters: Actuator type (piano), 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 to ensure electrical performance and reliability.

The 76PSB03T qualifies as a direct substitute based on complete parameter alignment across all electrical, mechanical, and environmental specifications.

Parameter Comparison

Engineering Selection Recommendations

The 76PSB03T is the direct functional equivalent of the 76PSB03. Selection of the 76PSB03T is supported by the following engineering criteria:

Product Status: The 76PSB03 is classified as obsolete. The 76PSB03T maintains active product status, ensuring continued availability and manufacturer support.

Regulatory Compliance: The 76PSB03T achieves ROHS3 compliance, whereas the 76PSB03 is RoHS non-compliant. For applications subject to RoHS directives or environmental regulations, the 76PSB03T provides superior compliance posture.

Electrical and Mechanical Equivalence: All electrical parameters (SPST circuit, 150mA, 30VDC), mechanical specifications (3-position piano actuator, through-hole right-angle mounting, 0.100" pitch), and environmental ratings (-40°C to 85°C operating range, 2,000-cycle life) are identical between both parts.

Packaging Consideration: The 76PSB03T is supplied in tube packaging, whereas the 76PSB03 packaging specification is not provided. Tube packaging is standard for DIP switches and presents no functional impact on component performance or PCB integration.

Frequently Asked Questions (FAQ)

Q: Can the 76PSB03T be used as a direct replacement for the 76PSB03 in existing designs?

A: Yes. The 76PSB03T is electrically and mechanically identical to the 76PSB03 across all specified parameters. No design modifications are required for substitution.

Q: What is the primary reason for substituting the 76PSB03?

A: The 76PSB03 is classified as obsolete product status. The 76PSB03T is the active equivalent, ensuring procurement continuity and manufacturer support.

Q: Does the RoHS compliance difference affect component functionality?

A: No. RoHS compliance status does not alter electrical or mechanical performance. The 76PSB03T's ROHS3 compliance provides regulatory advantage for applications subject to environmental directives.

Q: Are there any differences in packaging between the 76PSB03 and 76PSB03T?

A: The 76PSB03T is supplied in tube packaging. Tube packaging is standard for DIP switches and does not affect component performance or PCB assembly compatibility.

Q: What parameters must remain identical for substitution eligibility?

A: Circuit configuration (SPST), number of positions (3), current rating (150mA), voltage rating (30VDC), actuator type (piano), mounting type (through hole, right angle), pitch (0.100"), and operating temperature range (-40°C to 85°C) must all be identical.

Q: Is the 76PSB03T the only available substitute?

A: Based on the provided input parameters, the 76PSB03T is identified as the direct substitute. Both parts share the same base product number (76PSB) and series designation (76).
