Key Parameters

Substitute Part Grouping Explanation

The Mueller Electric Co BU-00281-2 is identified as an equivalent substitute for the Pomona Electronics 4098-2 based on the following critical parameters:

Matching Specifications:

• Standard binding post connector with knurled head design
• Red color designation
• Brass body with nickel plating
• Threaded termination capability
• Banana and tip connector category classification
• RoHS compliance (BU-00281-2 is RoHS Compliant; 4098-2 is ROHS3 Compliant)
• REACH Unaffected status for both parts

Substitution Considerations: The BU-00281-2 provides a higher current rating of 15A compared to the 4098-2's 3A rating, making it suitable for applications requiring equal or lower current demands. The insulation material differs (Polyamide/Nylon versus Polycarbonate), and specific mechanical dimensions such as cross hole diameter and head size are not provided for the substitute part. These differences do not preclude substitution in applications where the 4098-2 was previously used, provided the electrical and mechanical interface requirements are satisfied.

Parameter Comparison

Engineering Selection Recommendations

The Mueller Electric Co BU-00281-2 is the designated substitute for the obsolete Pomona Electronics 4098-2. Selection of the BU-00281-2 is supported by the following factors:

Product Status: The BU-00281-2 maintains active product status, ensuring ongoing availability and supply chain continuity. The 4098-2's obsolete classification necessitates transition to an alternative part for new designs and ongoing maintenance requirements.

Regulatory Compliance: Both parts satisfy RoHS and REACH requirements, with the BU-00281-2 carrying current RoHS Compliant certification. This ensures compatibility with modern procurement and environmental standards.

Electrical Performance: The BU-00281-2's 15A current rating exceeds the 4098-2's 3A specification, providing margin for applications operating at or below the original part's current requirements. Voltage rating information for the BU-00281-2 is not specified in available documentation; applications requiring specific voltage ratings should be evaluated against the 4098-2's 30VAC/60VDC specification.

Mechanical Compatibility: Both connectors feature identical knurled head design, red color designation, and threaded termination. The BU-00281-2 is suitable for panel mounting applications where the 4098-2 was previously deployed.

Frequently Asked Questions (FAQ)

Q: Can the Mueller BU-00281-2 directly replace the Pomona 4098-2 in existing applications?

A: Yes, the BU-00281-2 is functionally equivalent for applications operating at or below the 4098-2's 3A current rating. Both connectors feature identical knurled head design, red color, brass body with nickel plating, and threaded termination. Mechanical interface compatibility should be confirmed for specific panel mounting configurations.

Q: What is the primary reason for substitution?

A: The Pomona 4098-2 is classified as obsolete. The Mueller BU-00281-2 maintains active product status, ensuring reliable supply chain availability for new designs and replacement requirements.

Q: Are there differences in insulation material between these parts?

A: Yes. The 4098-2 uses Polycarbonate (PC) insulation, while the BU-00281-2 uses Polyamide (PA) and Nylon. Both materials are suitable for standard binding post connector applications. Application-specific temperature or chemical resistance requirements should be evaluated against material datasheets.

Q: Does the BU-00281-2 support wire wrap termination like the 4098-2?

A: The BU-00281-2 specification indicates threaded termination capability. Wire wrap termination support is not documented for the substitute part. Applications requiring wire wrap termination should confirm compatibility with the BU-00281-2 manufacturer or evaluate alternative substitutes.

Q: What is the current rating difference, and does it affect substitution?

A: The BU-00281-2 provides 15A current rating compared to the 4098-2's 3A rating. This higher rating is advantageous for applications operating at the original part's current specification or below, providing additional margin. Applications exceeding 3A should not use the 4098-2 regardless of availability.

Q: Are both parts RoHS and REACH compliant?

A: Yes. The 4098-2 is ROHS3 Compliant and REACH Unaffected. The BU-00281-2 is RoHS Compliant and REACH Unaffected. Both parts satisfy current environmental and regulatory requirements.

Q: What packaging is available for the BU-00281-2?

A: The BU-00281-2 is available in bulk packaging. The 4098-2 packaging specification is not documented. Procurement requirements should be confirmed with the supplier for specific packaging needs.
