Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 90HBW10P is determined by the following critical parameters:

Primary Compatibility Criteria:

• Circuit configuration (SPST)
• Number of positions (10)
• Mounting type (Surface Mount)
• Pitch spacing (0.100" / 2.54mm)
• Actuator type (Slide Standard)
• Termination style (Gull Wing)

Electrical Performance Criteria:

• Current rating must equal or exceed 25mA
• Voltage rating must equal or exceed 24VDC
• Operating temperature range must encompass -40°C to 85°C

Physical Compatibility Criteria:

• Height above board and overall dimensions must permit direct PCB placement
• Contact material and finish must support equivalent switching performance

Two substitute parts meet these criteria with varying degrees of parameter alignment and compliance status.

Parameter Comparison

Engineering Selection Recommendations

90HBW10PT (Grayhill Inc.)

The 90HBW10PT is the primary equivalent substitute for the 90HBW10P. Both components share identical electrical ratings (25mA, 24VDC), mechanical specifications, and physical dimensions. The 90HBW10PT is the active production variant of the same base product (90HBW10) and maintains full parameter compatibility. The 90HBW10PT carries ROHS3 compliance status, addressing regulatory requirements that the obsolete 90HBW10P does not meet. This part is recommended as the direct replacement for new designs and ongoing production support.

219-10LPST (CTS Electrocomponents)

The 219-10LPST is a cross-manufacturer substitute that maintains functional compatibility through equivalent circuit configuration, position count, mounting type, and pitch spacing. This part provides enhanced electrical performance with a 100mA current rating (exceeding the 25mA requirement) and an extended lower operating temperature limit (-55°C versus -40°C). However, the 219-10LPST operates at 20VDC maximum, which is below the 24VDC rating of the main part. This voltage differential requires circuit-level evaluation to confirm suitability for applications operating at or near 24VDC. The 219-10LPST offers superior moisture sensitivity performance (MSL 1 versus MSL 3) and ROHS3 compliance. Selection of this part is appropriate for applications where the 20VDC rating is acceptable and enhanced environmental performance is beneficial.

Frequently Asked Questions (FAQ)

Q: Can the 90HBW10PT be used as a direct replacement for the 90HBW10P?

A: Yes. The 90HBW10PT is functionally and physically equivalent to the 90HBW10P. Both components share identical electrical ratings (25mA, 24VDC), mechanical life (2,000 cycles), operating temperature range (-40°C to 85°C), and physical dimensions. The 90HBW10PT is the active production equivalent and is recommended for all applications currently using the obsolete 90HBW10P.

Q: What are the key differences between the 90HBW10PT and 219-10LPST?

A: The primary differences are manufacturer, voltage rating, current rating, and environmental specifications. The 90HBW10PT maintains the original 24VDC rating and 25mA current specification. The 219-10LPST operates at 20VDC maximum with a 100mA current rating. The 219-10LPST provides superior moisture sensitivity performance (MSL 1 versus MSL 3) and an extended lower temperature operating limit (-55°C versus -40°C). Both parts maintain identical circuit configuration, position count, pitch, and mounting type.

Q: Is the 219-10LPST suitable for 24VDC applications?

A: The 219-10LPST is rated for 20VDC maximum. Applications operating at 24VDC exceed this rating. Use of the 219-10LPST in 24VDC circuits requires circuit-level analysis to confirm that actual operating voltage remains within the 20VDC specification. This part is not recommended for applications where 24VDC is the nominal operating voltage.

Q: What is the difference between the packaging of these parts?

A: The 90HBW10P and 90HBW10PT are supplied in tape seal packaging. The 219-10LPST is supplied in tube packaging. Both packaging formats are standard for surface mount DIP switches and do not affect electrical or mechanical performance. Packaging selection may influence handling, storage, and automated assembly considerations.

Q: Are all three parts RoHS compliant?

A: The 90HBW10P is RoHS non-compliant. Both the 90HBW10PT and 219-10LPST are ROHS3 compliant. For applications subject to RoHS regulatory requirements, either the 90HBW10PT or 219-10LPST must be selected.

Q: What is the MSL rating and why does it matter?

A: MSL (Moisture Sensitivity Level) indicates the component's sensitivity to moisture absorption during storage and handling. The 90HBW10P and 90HBW10PT carry MSL 3 (168 hours), requiring controlled storage conditions and bake-out procedures before reflow soldering. The 219-10LPST carries MSL 1 (Unlimited), indicating no moisture sensitivity and no special storage or handling requirements. MSL rating affects supply chain logistics and manufacturing process requirements.
