Key Parameters

Substitute Part Grouping Explanation

Substitution of the 90HBJ07P is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Circuit configuration (SPST), number of positions (7), current rating (25mA), and voltage rating (24VDC) must remain identical.

Mechanical Parameters: Actuator type (Slide Standard), mounting type (Surface Mount), termination style (J Lead), pitch (0.100"), and height above board (0.220") must match exactly.

Environmental Parameters: Operating temperature range (-40°C to 85°C) and moisture sensitivity level (MSL 3) must be maintained.

Material Specifications: Contact material (Copper Alloy) and contact finish (Gold) must be preserved to ensure electrical performance and reliability.

The substitute part 90HBJ07PT meets all these criteria while offering improved product status and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The 90HBJ07PT is the direct substitute for the obsolete 90HBJ07P. Both parts are manufactured by Grayhill Inc. and share identical electrical, mechanical, and environmental specifications across all critical parameters.

Product Status Consideration: The 90HBJ07P is classified as obsolete, while the 90HBJ07PT maintains active product status. Selection of the active substitute ensures ongoing manufacturer support, availability, and supply chain continuity.

Regulatory Compliance: The 90HBJ07PT achieves RoHS3 compliance, whereas the 90HBJ07P is RoHS non-compliant. For applications subject to RoHS requirements or future regulatory transitions, the 90HBJ07PT provides compliance assurance. Both parts maintain REACH Unaffected status and EAR99 export classification.

Packaging Difference: The 90HBJ07PT is supplied in tube packaging, compared to standard packaging for the 90HBJ07P. Packaging selection should align with assembly process requirements and inventory management protocols.

Functional Equivalence: No functional or performance differences exist between these parts. The 90HBJ07PT is a direct replacement suitable for new designs, redesigns, and legacy system support where the 90HBJ07P is currently specified.

Frequently Asked Questions (FAQ)

Q: Can the 90HBJ07PT be used as a direct replacement for the 90HBJ07P in existing designs?

A: Yes. The 90HBJ07PT is functionally and mechanically equivalent to the 90HBJ07P. All electrical parameters, mechanical dimensions, and environmental ratings are identical. The substitute part is suitable for direct PCB assembly without design modification.

Q: What is the primary difference between these two parts?

A: The 90HBJ07PT is the active production equivalent of the obsolete 90HBJ07P. The substitute offers improved product status, RoHS3 compliance, and tube packaging. Electrical and mechanical specifications are identical.

Q: Does the RoHS3 compliance of the 90HBJ07PT affect compatibility?

A: No. RoHS3 compliance is a material composition specification that does not alter electrical performance, mechanical fit, or functional behavior. The 90HBJ07PT is fully compatible with applications designed for the 90HBJ07P.

Q: Are there any circuit board layout considerations when substituting the 90HBJ07PT?

A: No. Both parts share identical pitch (0.100"), height above board (0.220"), termination style (J Lead), and mounting type (Surface Mount). No PCB layout modifications are required.

Q: What packaging options are available for the 90HBJ07PT?

A: The 90HBJ07PT is supplied in tube packaging. The original 90HBJ07P used standard packaging. Tube packaging is suitable for automated assembly processes and standard component handling.

Q: Are both parts suitable for the operating temperature range of -40°C to 85°C?

A: Yes. Both the 90HBJ07P and 90HBJ07PT are rated for identical operating temperature range of -40°C to 85°C and maintain equivalent mechanical and electrical life specifications across this range.

Q: What is the moisture sensitivity level for these parts?

A: Both parts are classified as MSL 3 (168 Hours). This specification applies to both the main part and substitute, requiring standard moisture control during storage and handling.
