Equivalent & Substitute Parts for 90HBJ04P DIP Switch

Part Overview

The 90HBJ04P is a surface mount DIP switch manufactured by Grayhill Inc., configured as a 4-position SPST (Single Pole Single Throw) slide actuator switch rated for 25mA at 24VDC. This component is classified as obsolete, which necessitates identification of active equivalent parts for ongoing procurement and design continuity. The switch features gold-plated copper alloy contacts, flush/recessed actuator design, and J-lead termination suitable for standard PCB assembly processes.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 90HBJ04P is based on electrical and mechanical parameter equivalence within the Grayhill 90HB series. The substitute part 90HBJ04PT maintains identical functional specifications across all critical parameters: SPST circuit configuration, 4-position count, 25mA current rating, 24VDC voltage rating, slide actuator type with flush/recessed actuation level, copper alloy gold-plated contacts, surface mount configuration with J-lead termination, 0.100" pitch, and identical mechanical/electrical life ratings of 2,000 cycles.

The primary distinction between these parts is product status and packaging format. The 90HBJ04P is obsolete with standard packaging, while 90HBJ04PT is an active product supplied in tube packaging. Both components operate within the identical temperature range (-40°C to 85°C) and share the same physical dimensions and board height specifications.

Parameter Comparison

Engineering Selection Recommendations

The 90HBJ04PT is the direct active equivalent for the obsolete 90HBJ04P. Both parts are functionally identical across all electrical and mechanical parameters, with identical board height, pitch spacing, and contact specifications enabling direct PCB footprint compatibility.

The primary consideration for component selection is regulatory compliance. The 90HBJ04P carries RoHS non-compliant status, while the 90HBJ04PT achieves ROHS3 compliance. For new designs or applications subject to RoHS directives, the 90HBJ04PT is the appropriate selection. Both parts maintain REACH Unaffected status and identical export classification (EAR99).

Packaging format differs between the two parts: 90HBJ04P uses standard packaging while 90HBJ04PT is supplied in tube format. This distinction affects handling and assembly processes but does not impact electrical or mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can 90HBJ04PT be used as a direct replacement for 90HBJ04P in existing designs?

A: Yes. The 90HBJ04PT maintains identical electrical specifications (25mA, 24VDC, SPST 4-position), mechanical dimensions (0.220" height, 0.100" pitch), contact materials (gold-plated copper alloy), and actuator characteristics (flush/recessed slide type). PCB footprints are identical, enabling direct substitution without design modification.

Q: What is the difference between these two parts?

A: The primary differences are product status and regulatory compliance. The 90HBJ04P is obsolete and RoHS non-compliant, while the 90HBJ04PT is an active product with ROHS3 compliance. Packaging format also differs: standard versus tube. All functional and mechanical parameters are identical.

Q: Does the tube packaging of 90HBJ04PT affect performance?

A: No. Packaging format is a logistics and handling consideration only. It does not affect electrical performance, mechanical life, contact characteristics, or operating specifications. Both parts deliver identical functional performance in circuit applications.

Q: Are there any temperature or environmental differences between these parts?

A: No. Both parts operate across the identical temperature range (-40°C to 85°C), maintain identical moisture sensitivity level (MSL 3, 168 hours), and feature identical washable and tape seal characteristics.

Q: Which part should be selected for new designs?

A: The 90HBJ04PT should be selected for new designs. It is an active product with ROHS3 compliance, ensuring long-term availability and regulatory alignment. The 90HBJ04P is obsolete and should be reserved for legacy system maintenance only.
