Key Parameters

Substitute Part Grouping Explanation

Substitution of the BU-31608-0 is based on the following critical parameters that must align for functional equivalence:

Primary Matching Criteria:

• Connector type: Tip Jack (Female gender)
• Mating interface: Standard Tip diameter
• Mounting configuration: Panel Mount
• Insulation: Mating End Insulated
• Color: Black
• Moisture Sensitivity Level: 1 (Unlimited)

Secondary Consideration:

• Termination method: The BU-31608-0 uses solderless termination. Substitute parts may employ alternative termination methods (such as solder eyelet) provided the mechanical and electrical interface remains compatible with standard tip mating plugs.

The substitute part 105-0803-001 satisfies all primary matching criteria and maintains functional compatibility despite employing solder eyelet termination instead of solderless design.

Parameter Comparison

Engineering Selection Recommendations

The 105-0803-001 serves as a direct functional substitute for the obsolete BU-31608-0 based on matching mechanical and electrical interface specifications. Key selection factors include:

Product Status: The BU-31608-0 is obsolete with limited inventory availability (952 pcs). The 105-0803-001 is active with substantially higher inventory (3847 pcs), ensuring long-term component availability.

Compliance Posture: The 105-0803-001 achieves ROHS3 compliance and REACH affected status, whereas the BU-31608-0 is RoHS non-compliant. Systems requiring regulatory compliance should prioritize the 105-0803-001.

Termination Transition: While the BU-31608-0 employs solderless termination and the 105-0803-001 uses solder eyelet termination, both maintain identical mating interface geometry (standard tip, female gender, panel mount). Circuit board layout modifications may be required to accommodate solder eyelet termination in place of solderless connection points.

Frequently Asked Questions (FAQ)

Q: Can the 105-0803-001 directly replace the BU-31608-0 without design changes?

A: The 105-0803-001 maintains mechanical and electrical compatibility at the mating interface (standard tip, female gender, panel mount, mating end insulated). However, termination method differs (solder eyelet versus solderless), requiring PCB layout or wiring harness modifications to accommodate the alternative connection approach.

Q: What is the significance of the termination method difference?

A: Solderless termination (BU-31608-0) typically uses compression or spring-based wire attachment, while solder eyelet termination (105-0803-001) requires solder joint formation. Both methods achieve electrical connection; the selection depends on assembly process capability and design requirements.

Q: Are there packaging differences between these parts?

A: The BU-31608-0 packaging is not specified in available data. The 105-0803-001 is supplied in bulk packaging. Confirm packaging requirements with your procurement specification.

Q: Why is RoHS compliance status different?

A: The BU-31608-0 predates RoHS3 requirements (obsolete status). The 105-0803-001, as an active product, meets current ROHS3 compliance standards. Systems subject to regulatory requirements should specify the 105-0803-001.

Q: Are the contact materials and finishes compatible?

A: The BU-31608-0 contact material and finish are not specified. The 105-0803-001 features phosphor bronze contacts with tin finish. Both maintain standard tip mating geometry; contact material differences do not affect mechanical compatibility.

Q: What is the operating temperature range consideration?

A: The BU-31608-0 operating temperature is not specified. The 105-0803-001 operates from -55°C to 85°C. Confirm your application temperature requirements against the 105-0803-001 specification.
