Key Parameters

Substitute Part Grouping Explanation

Substitution of the Grayhill 76PSB07 is determined by strict equivalence across the following critical parameters:

• Circuit Configuration: SPST topology must be maintained
• Position Count: 7-position requirement is non-negotiable
• Electrical Ratings: 150mA current and 30VDC voltage ratings must be met or exceeded
• Mechanical Interface: Through-hole, right-angle mounting with 0.100" (2.54mm) pitch ensures PCB compatibility
• Physical Envelope: Height above board (0.301") and length (0.780") must match to prevent mechanical interference
• Actuator Style: Piano-type raised actuator is required for functional equivalence
• Contact System: Copper alloy with gold finish provides equivalent electrical performance and reliability

The substitute part 76PSB07T meets all these criteria while offering improved product status (Active vs. Obsolete) and enhanced compliance certification.

Engineering Selection Recommendations

Primary Recommendation: 76PSB07T

The 76PSB07T is the direct functional equivalent of the 76PSB07 and is the appropriate substitute for all applications. Selection of 76PSB07T is justified on the following engineering grounds:

1. Electrical Equivalence: All electrical parameters (circuit type, current rating, voltage rating, contact material, and contact finish) are identical, ensuring drop-in compatibility in existing circuit designs.

2. Mechanical Compatibility: Identical mounting configuration, pitch, height above board, and physical dimensions guarantee PCB-level compatibility without layout modifications.

3. Product Status: The 76PSB07T maintains Active product status, ensuring long-term availability and supply chain continuity compared to the Obsolete 76PSB07.

4. Regulatory Compliance: The 76PSB07T is RoHS3 Compliant, meeting current environmental and regulatory requirements. The original 76PSB07 is RoHS Non-Compliant, which may present compliance issues for new designs or updated manufacturing standards.

5. Packaging: The 76PSB07T is supplied in Tube packaging, which provides better component protection and handling efficiency compared to bulk packaging.

6. Certification Alignment: Both parts share identical REACH Status (REACH Unaffected) and ECCN classification (EAR99), maintaining consistent export and regulatory documentation.

Frequently Asked Questions (FAQ)

Q: Can the 76PSB07T be used as a direct replacement for the 76PSB07 without PCB modifications?

A: Yes. The 76PSB07T is electrically and mechanically identical to the 76PSB07. All electrical ratings, mounting dimensions, pitch, and actuator specifications match exactly. No PCB layout changes are required.

Q: What is the difference between the 76PSB07 and 76PSB07T?

A: The primary differences are product status and compliance certification. The 76PSB07 is Obsolete and RoHS Non-Compliant, while the 76PSB07T is Active and RoHS3 Compliant. Packaging also differs: 76PSB07 is bulk, 76PSB07T is tube. All functional and electrical parameters are identical.

Q: Why is the 76PSB07 listed as Obsolete?

A: Obsolete status indicates that the manufacturer has discontinued active production and support for this part number. The 76PSB07T represents the current active equivalent in the Grayhill 76 series.

Q: Are there any compatibility concerns when switching from 76PSB07 to 76PSB07T?

A: No compatibility concerns exist. The parts are functionally equivalent across all specified parameters. The 76PSB07T is a direct substitute with no design or application limitations.

Q: Does the tube packaging of 76PSB07T affect component performance?

A: No. Packaging format does not affect electrical or mechanical performance. Tube packaging provides improved component protection during storage and handling compared to bulk packaging.

Q: What is the significance of RoHS3 Compliance for the 76PSB07T?

A: RoHS3 Compliance indicates that the 76PSB07T meets current European Union Restriction of Hazardous Substances regulations. This is important for applications subject to environmental compliance requirements or for designs intended for markets with strict regulatory standards.

Q: Can I use the 76PSB07T in legacy systems originally designed with the 76PSB07?

A: Yes. The 76PSB07T is fully compatible with all applications and systems originally designed for the 76PSB07. No circuit modifications, firmware updates, or system reconfiguration is necessary.

Q: What is the base product number for these parts?

A: The base product number is 76PSB, which identifies the core switch family within the Grayhill 76 series. Both 76PSB07 and 76PSB07T are variants of this base product.
