Key Parameters

Substitute Part Grouping Explanation

The 76PSB12T qualifies as a direct equivalent substitute based on identical electrical and mechanical parameters. Substitution compatibility is established through the following critical parameters:

Electrical Compatibility:

• Identical circuit configuration (SPST)
• Matching current rating (150mA)
• Matching voltage rating (30VDC)
• Identical operating temperature range (-40°C to 85°C)

Mechanical Compatibility:

• Identical number of positions (12)
• Matching actuator type (Piano)
• Identical mounting configuration (Through Hole, Right Angle)
• Matching pitch specification (0.100" / 2.54mm)
• Identical height above board (0.301" / 7.65mm)
• Identical length (1.280" / 32.51mm)

Physical Characteristics:

• Matching contact material (Copper Alloy)
• Matching contact finish (Gold)
• Identical termination style (PC Pin)
• Matching body material (Thermoplastic)

Performance Specifications:

• Identical mechanical life (2,000 Cycles)
• Identical electrical life (2,000 Cycles)

The primary distinction between these components is product status and packaging format, with 76PSB12T representing the active production equivalent.

Engineering Selection Recommendations

The 76PSB12T is the direct equivalent substitute for the obsolete 76PSB12 component. Selection of the 76PSB12T is based on the following engineering criteria:

Product Status Consideration: The 76PSB12 is classified as obsolete, indicating discontinued manufacturing and limited procurement availability. The 76PSB12T maintains active product status with Grayhill Inc., ensuring reliable supply chain access and continued manufacturer support.

Regulatory Compliance: The 76PSB12T achieves ROHS3 compliance, whereas the 76PSB12 is RoHS non-compliant. For applications subject to RoHS directives or customer compliance requirements, the 76PSB12T satisfies current regulatory standards.

Electrical and Mechanical Equivalence: All critical electrical parameters (current rating, voltage rating, circuit configuration) and mechanical parameters (mounting type, pitch, dimensions, actuator type) are identical between the two components, establishing full functional interchangeability.

Packaging Consideration: The 76PSB12T is supplied in tube packaging, whereas the 76PSB12 was supplied in bulk format. Packaging format does not affect electrical or mechanical performance and is determined by procurement volume and handling requirements.

Frequently Asked Questions (FAQ)

Q: Can the 76PSB12T be used as a direct replacement for the 76PSB12 in existing designs?

A: Yes. The 76PSB12T is electrically and mechanically identical to the 76PSB12. All critical parameters including circuit configuration, current rating, voltage rating, actuator type, mounting configuration, and pitch are identical. The component can be substituted without design modification.

Q: What is the difference between the 76PSB12 and 76PSB12T?

A: The primary differences are product status and packaging format. The 76PSB12 is obsolete and supplied in bulk packaging. The 76PSB12T is an active product supplied in tube packaging and achieves ROHS3 compliance. Electrical and mechanical specifications are identical.

Q: Does the tube packaging of the 76PSB12T affect compatibility with PCB assembly processes?

A: No. Packaging format does not affect component electrical performance or mechanical fit. Tube packaging is a supply format consideration and does not impact PCB mounting, soldering, or functional operation.

Q: Is the 76PSB12T RoHS compliant?

A: Yes. The 76PSB12T achieves ROHS3 compliance. The original 76PSB12 is RoHS non-compliant. For applications requiring RoHS compliance, the 76PSB12T satisfies regulatory requirements.

Q: Are there any electrical performance differences between the 76PSB12 and 76PSB12T?

A: No. Both components have identical electrical specifications: 150mA current rating, 30VDC voltage rating, SPST circuit configuration, 2,000 cycle electrical life, and -40°C to 85°C operating temperature range.

Q: Can the 76PSB12T be used in new production designs?

A: Yes. The 76PSB12T is an active product with full manufacturer support. It is suitable for new production designs and provides long-term supply chain availability compared to the obsolete 76PSB12.
