Key Parameters

Substitute Part Grouping Explanation

The Mueller Electric Co BU-P4543-2 qualifies as a direct equivalent substitute based on the following critical parameters:

Matching Parameters:

• Connector type: Tip Jack, Double
• Gender: Female
• Plug/mating plug diameter: Standard Tip
• Mounting type: Panel Mount
• Termination: Turret
• Insulation: Mating End Insulated
• Contact material: Beryllium Copper
• Contact finish: Gold
• Color: Black, Red
• Electrical category: Banana and Tip Connectors

Compliance Alignment:

• RoHS compliance maintained (RoHS Compliant vs ROHS3 Compliant)
• REACH status: REACH Unaffected (both parts)
• ECCN classification: EAR99 (both parts)
• HTSUS code: 8536.69.4030 (both parts)

The primary difference is body material composition: Polycarbonate Thermoplastic (4543-2) versus Polyamide (PA), Nylon (BU-P4543-2), with an extended operating temperature range for the substitute part (-50°C ~ 120°C versus 115°C maximum).

Parameter Comparison

Engineering Selection Recommendations

Both the Pomona Electronics 4543-2 and Mueller Electric Co BU-P4543-2 are active production parts with equivalent electrical and mechanical specifications for standard tip jack turret connector applications. Selection between these parts should be based on:

Pomona 4543-2: Primary choice when polycarbonate thermoplastic body material is specified or preferred for the application. ROHS3 compliance provides enhanced regulatory alignment for certain markets.

Mueller BU-P4543-2: Suitable alternative when extended low-temperature operation is required (-50°C minimum rating). Polyamide nylon body material offers different mechanical properties. RoHS compliance status meets standard regulatory requirements.

Both parts maintain identical electrical characteristics, contact materials, and termination methods, ensuring functional interchangeability in panel mount turret connector applications.

Frequently Asked Questions (FAQ)

Q: Are these connectors electrically interchangeable? A: Yes. Both parts feature identical contact material (Beryllium Copper), contact finish (Gold), and electrical configuration as double tip jack turrets with female gender and standard tip diameter.

Q: What is the difference in body material, and does it affect performance? A: The Pomona 4543-2 uses Polycarbonate Thermoplastic, while the Mueller BU-P4543-2 uses Polyamide (PA), Nylon. Both materials are suitable for panel mount applications. Material selection depends on specific mechanical and thermal requirements of the end application.

Q: Can I use the Mueller part as a direct replacement for the Pomona part? A: Yes, provided the application does not require the specific body material or ROHS3 compliance designation of the original Pomona part. Both maintain identical connector type, gender, mounting configuration, and termination method.

Q: What is the operating temperature difference? A: The Pomona 4543-2 operates to 115°C maximum. The Mueller BU-P4543-2 operates from -50°C to 120°C, providing extended low-temperature capability and slightly higher maximum temperature rating.

Q: Are both parts RoHS compliant? A: Yes. The Pomona 4543-2 is ROHS3 Compliant. The Mueller BU-P4543-2 is RoHS Compliant. Both meet RoHS regulatory requirements.

Q: What packaging is available? A: Both parts are supplied in bulk packaging format.
