Key Parameters

Substitute Part Grouping Explanation

Substitution of the 90HBJ03P is determined by strict equivalence across electrical and mechanical parameters. The primary substitute, 90HBJ03PT, maintains identical specifications in the following critical areas:

Electrical Parameters: Circuit configuration (SPST), number of positions (3), current rating (25mA), and voltage rating (24VDC) are identical.

Mechanical Parameters: Mounting type (surface mount), termination style (J lead), pitch (0.100"), actuator type (slide standard), and actuator level (flush, recessed) are identical.

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

Physical Dimensions: Height above board (0.220"), length (0.370"), and contact material (copper alloy with gold finish) are identical.

The 90HBJ03PT differs from the 90HBJ03P in product status (active versus obsolete) and packaging format (tube versus standard), with the substitute also offering improved RoHS3 compliance status.

Parameter Comparison

Engineering Selection Recommendations

The 90HBJ03PT is the direct equivalent substitute for the 90HBJ03P. Selection of the 90HBJ03PT is based on the following engineering criteria:

Product Status: The 90HBJ03P is classified as obsolete. The 90HBJ03PT maintains active product status, ensuring continued availability and manufacturer support for new designs and production replenishment.

Regulatory Compliance: The 90HBJ03PT achieves ROHS3 compliance, whereas the 90HBJ03P is RoHS non-compliant. This compliance improvement aligns with current environmental regulations and procurement requirements in regulated markets.

Electrical and Mechanical Equivalence: All electrical parameters (SPST circuit, 3 positions, 25mA, 24VDC), mechanical parameters (surface mount, J lead, 0.100" pitch, slide actuator), and environmental specifications (operating temperature, mechanical life, electrical life) are identical between the two parts.

Packaging Consideration: The 90HBJ03PT is supplied in tube packaging, whereas the 90HBJ03P uses standard packaging. Tube packaging is compatible with automated assembly processes and does not affect functional performance.

Frequently Asked Questions (FAQ)

Q: Can the 90HBJ03PT be used as a direct replacement for the 90HBJ03P in existing designs?

A: Yes. The 90HBJ03PT is electrically and mechanically equivalent to the 90HBJ03P. All functional parameters, including circuit configuration, current and voltage ratings, actuator type, mounting method, and termination style, are identical. No design modifications are required.

Q: What is the difference between the 90HBJ03P and 90HBJ03PT?

A: The primary differences are product status and compliance. The 90HBJ03P is obsolete and RoHS non-compliant. The 90HBJ03PT is active and ROHS3 compliant. Packaging differs (standard versus tube), but this does not affect electrical or mechanical performance.

Q: Does the tube packaging of the 90HBJ03PT affect compatibility with PCB assembly equipment?

A: No. Tube packaging is standard for automated pick-and-place assembly systems. The component dimensions, pitch, and termination style remain unchanged and are fully compatible with standard surface mount assembly processes.

Q: Are there any electrical performance differences between these parts?

A: No. Both parts are rated for 25mA at 24VDC, feature identical contact materials (copper alloy with gold finish), and have identical mechanical and electrical life ratings (2,000 cycles each). Operating temperature range is identical (-40°C to 85°C).

Q: Why should I transition from the 90HBJ03P to the 90HBJ03PT?

A: The 90HBJ03P is obsolete, which limits future availability and manufacturer support. The 90HBJ03PT is an active product with improved RoHS3 compliance, ensuring long-term supply chain reliability and regulatory alignment.

Q: Are the physical dimensions identical between these parts?

A: Yes. Height above board (0.220"), length (0.370"), pitch (0.100"), and all other physical dimensions are identical. PCB layout and footprint design require no modification.
