Grayhill 83BA1-002 Keypad Switch Equivalent & Substitute Parts

Part Overview

The Grayhill 83BA1-002 is a 16-key matrix keypad switch featuring snap dome contacts, polymer keys, and non-illuminated operation at 0.01A @ 24VDC. This component is classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing system support and new design implementations. The 4x4 matrix configuration with fixed legend (0-9, A-F) and panel mount termination defines its primary application scope.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 83BA1-002 is determined by the following critical parameters:

Core Functional Requirements (Non-Negotiable):

• 16-key configuration
• 4x4 matrix output architecture
• Snap dome switch mechanism
• 0.01A @ 24VDC contact rating
• Non-illuminated operation
• Panel mount, front-facing installation
• Pin header termination
• Fixed legend type with 0-9, A-F designation

Allowable Variations:

• Key material composition (polymer vs. rubber overlay)
• Operating temperature range (provided minimum and maximum are met or exceeded)
• Ingress protection rating (enhancement permitted)
• Product status (active preferred over obsolete)
• Compliance certifications (RoHS3 acceptable as upgrade from RoHS)

The 84S-BB2-014 meets all core functional requirements while offering enhanced environmental protection and active product status.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement Applications:

The 84S-BB2-014 is the qualified substitute for the obsolete 83BA1-002. Both components share identical electrical specifications, matrix architecture, and mechanical mounting interfaces. The 84S-BB2-014 maintains backward compatibility while providing:

• Extended operating temperature range (-55°C to 85°C vs. -40°C to 80°C)
• IP67 ingress protection rating for enhanced environmental durability
• Active product status with ongoing manufacturer support
• ROHS3 compliance alignment with current regulatory standards

Compliance Considerations:

Both parts maintain RoHS compliance and REACH unaffected status. The 84S-BB2-014 represents the current generation equivalent with no functional degradation relative to the 83BA1-002.

Inventory and Availability:

The 84S-BB2-014 is available in active inventory (696 pcs) with bulk packaging, supporting both prototype and production-volume requirements.

Frequently Asked Questions (FAQ)

Q: Can the 84S-BB2-014 directly replace the 83BA1-002 in existing designs?

A: Yes. Both components feature identical 4x4 matrix output, 0.01A @ 24VDC contact rating, pin header termination, and panel mount configuration. No circuit modifications are required.

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

A: The 84S-BB2-014 uses a rubber overlay key construction versus the polymer keys in the 83BA1-002. Both achieve identical tactile response and 3,000,000-cycle operational life. The 84S-BB2-014 additionally provides IP67 ingress protection and extended temperature range.

Q: Does the rubber overlay key material affect electrical performance?

A: No. Both key materials operate identically within the specified 0.01A @ 24VDC contact rating and snap dome switching mechanism.

Q: Is the extended temperature range of the 84S-BB2-014 a concern for existing applications?

A: No. The extended range (-55°C to 85°C) is a superset of the original specification (-40°C to 80°C). Applications operating within the original range experience no change in performance.

Q: What does IP67 rating on the 84S-BB2-014 provide?

A: IP67 certification indicates dust-tight and waterproof operation. The 83BA1-002 does not specify ingress protection. The 84S-BB2-014 provides enhanced environmental protection for applications requiring moisture or particulate resistance.

Q: Are there any packaging differences between these parts?

A: The 83BA1-002 is listed with unspecified packaging; the 84S-BB2-014 is supplied in bulk packaging. Both use identical pin header termination and panel mount interfaces.

Q: Does the shielded feature of the 84S-BB2-014 affect compatibility?

A: No. Shielding is an enhancement that reduces electromagnetic interference without affecting electrical interface or mechanical compatibility.

Q: What is the current availability status of the 83BA1-002?

A: The 83BA1-002 is classified as obsolete. The 84S-BB2-014 is the active equivalent with ongoing manufacturer support and current inventory availability.
