Equivalent & Substitute Parts for 90HBJ05RT

Part Overview

The 90HBJ05RT is a DIP switch manufactured by Grayhill Inc., configured as a 5-position surface mount SPST (Single Pole Single Throw) device with slide actuator. This component operates at 24VDC with a 25mA current rating and is designed for applications requiring reliable switching in compact form factors. The part is currently in active production status with full RoHS compliance and REACH unaffected designation.

Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and functional characteristics align with the original specification, enabling direct replacement in circuit designs without functional degradation.

Substitute Part Grouping Explanation

Substitution eligibility for the 90HBJ05RT is determined by strict alignment of the following parameters:

Primary Compatibility Criteria:

• Circuit configuration must be SPST
• Number of positions must be 5
• Voltage rating must be 24VDC or higher
• Current rating must support 25mA or greater
• Mounting type must be surface mount
• Pitch must be 0.100" (2.54mm)
• Termination style must be J Lead
• Operating temperature range must encompass -40°C to 85°C

Secondary Compatibility Factors:

• Actuator type and level (slide, flush/recessed configuration)
• Contact material and finish specifications
• Mechanical and electrical life cycle ratings
• Regulatory compliance status (RoHS, REACH, ECCN)

The substitute part ADF05STTR04 (TE Connectivity ALCOSWITCH Switches) meets all primary electrical and mechanical criteria for direct substitution in the 90HBJ05RT application.

Engineering Selection Recommendations

90HBJ05RT Selection Criteria:

• Active production status with established supply chain
• RoHS Compliant certification for regulated markets
• REACH Unaffected status for European applications
• EAR99 export classification for unrestricted distribution
• Established mechanical life rating of 2,000 cycles

ADF05STTR04 Selection Criteria:

• Active production status with higher inventory availability (8,244 units vs. 1,005 units)
• ROHS3 Compliant certification meeting current regulatory requirements
• MSL 1 rating provides superior moisture protection compared to MSL 3
• Washable design enables post-assembly cleaning processes
• EAR99 export classification for unrestricted distribution
• Equivalent electrical and mechanical specifications for direct substitution

Both parts maintain active product status and full regulatory compliance. The ADF05STTR04 offers operational advantages through improved moisture sensitivity handling and washability, while maintaining electrical and mechanical equivalence to the 90HBJ05RT.

Frequently Asked Questions (FAQ)

Q: Can ADF05STTR04 be used as a direct replacement for 90HBJ05RT in existing PCB designs?

A: Yes. Both parts share identical circuit configuration (SPST), position count (5), mounting type (surface mount), actuator type (standard slide), and actuator level (flush/recessed). The 0.100" pitch and J Lead termination are equivalent, enabling direct PCB footprint compatibility.

Q: What is the difference in moisture sensitivity between these parts?

A: The 90HBJ05RT carries MSL 3 rating (168-hour floor life), while the ADF05STTR04 carries MSL 1 rating (unlimited floor life). MSL 1 provides superior protection against moisture absorption during storage and handling, reducing risk of solder joint degradation in humid environments.

Q: Does the washable feature of ADF05STTR04 affect electrical performance?

A: No. Washability is a manufacturing and assembly process capability that does not alter electrical switching characteristics, voltage rating, current capacity, or operating temperature range. Both parts maintain equivalent electrical specifications.

Q: Are there any packaging differences between these substitutes?

A: The 90HBJ05RT packaging is listed as standard, while ADF05STTR04 is supplied in Cut Tape (CT) format. Both are surface mount configurations suitable for automated assembly processes.

Q: What regulatory certifications apply to both parts?

A: Both parts carry RoHS compliance (90HBJ05RT: RoHS Compliant; ADF05STTR04: ROHS3 Compliant), EAR99 export classification, and equivalent HTSUS coding (8536.50.9065). The 90HBJ05RT is REACH Unaffected; the ADF05STTR04 status is Vendor Undefined.

Q: Can these parts be used interchangeably in high-temperature applications?

A: Both parts specify operating temperature range of -40°C to 85°C. Applications requiring operation beyond this envelope require alternative component selection.
