Molex 0440500007 Equivalent & Substitute Parts

Part Overview

The Molex 0440500007 is a shielded modular jack connector (8p8c/RJ45) with 90° right-angle orientation, designed for Ethernet and Cat5 applications. This through-hole solder-terminated connector features board lock functionality and EMI shielding with phosphor bronze contacts finished in gold. The part is active in production with ROHS3 compliance and unlimited moisture sensitivity rating.

Substitute parts are necessary when the primary part experiences supply constraints, extended lead times, or when design requirements permit functional equivalents from alternative manufacturers while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment with the following parameters:

• Connector type: Jack (RJ45/8p8c modular)
• Contact configuration: 8 positions, 8 contacts
• Mounting method: Through hole solder termination
• Physical orientation: 90° right-angle
• Electrical shielding: Shielded construction
• Contact material composition: Phosphor bronze or equivalent conductive alloy
• Contact finish: Gold plating
• Compliance: ROHS3 or equivalent regulatory status
• Moisture sensitivity: MSL 1 (unlimited)

All substitute parts listed meet these core criteria. Variations in operating temperature range, housing material composition, and optional features (board lock, filter, LED indicators) do not preclude substitution when the primary electrical and mechanical interfaces remain functionally equivalent.

Parameter Comparison

Engineering Selection Recommendations

All Amphenol FRJAE series parts (FRJAE-418, FRJAE-438, FRJAE-468, FRJAE-488) provide direct functional equivalence to the Molex 0440500007. These parts maintain identical contact configuration, mounting geometry, solder termination, and shielding architecture. The extended operating temperature range (-55°C to 85°C) of the Amphenol variants provides additional thermal margin compared to the Molex specification (-40°C to 85°C). All parts carry RoHS compliance certification and unlimited moisture sensitivity rating.

The Würth Elektronik 7499010211A operates within a narrower temperature range (0°C to 70°C) and features tin contact material with reduced gold plating thickness (30.0µin versus 50.0µin). This part is suitable for applications where the operating environment remains within 0°C to 70°C and where the reduced contact finish thickness does not conflict with design requirements. The Würth part includes integrated LED indicators (green-yellow) and AutoMDIX functionality, which may introduce additional considerations in applications where these features are not required.

Selection should prioritize parts with inventory availability and operating temperature ranges that match or exceed application requirements. All listed substitutes maintain ECCN EAR99 and HTSUS 8536.69.4040 classifications consistent with the primary part.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol FRJAE series parts directly replace the Molex 0440500007 in existing PCB designs?

A: Yes. The Amphenol FRJAE-418, FRJAE-438, FRJAE-468, and FRJAE-488 maintain identical through-hole solder pad footprints, 90° right-angle orientation, and 8p8c contact configuration. No PCB layout modifications are required.

Q: What is the significance of the contact finish thickness difference between the Molex part and Würth 7499010211A?

A: The Molex 0440500007 and Amphenol FRJAE variants specify 50.0µin (1.27µm) gold plating, while the Würth 7499010211A specifies 30.0µin (0.76µm). Both thicknesses meet standard Ethernet connector specifications. The thicker plating on the Molex and Amphenol parts provides additional corrosion resistance in extended-life applications.

Q: Are the Amphenol FRJAE parts suitable for Cat5 Ethernet applications?

A: The Amphenol FRJAE series parts are designed for RJ45 modular connector applications and maintain the electrical characteristics required for Ethernet transmission. The Molex 0440500007 explicitly specifies Cat5 rating; the Amphenol parts do not list specific category ratings but are functionally compatible with Cat5 and Cat5e standards based on their 8p8c configuration and shielded construction.

Q: What are the key differences between FRJAE-418, FRJAE-438, FRJAE-468, and FRJAE-488?

A: All four Amphenol FRJAE variants share identical electrical and mechanical specifications. The primary differences are optional features: FRJAE-418 and FRJAE-488 include board lock functionality; FRJAE-438 and FRJAE-468 include both board lock and filter features. These feature variations do not affect core connector compatibility.

Q: Is the Würth 7499010211A recommended as a primary substitute?

A: The Würth part meets core substitution criteria but operates within a narrower temperature range (0°C to 70°C versus -40°C to 85°C for the Molex part). Selection of the Würth part should be limited to applications where the operating environment remains within 0°C to 70°C. The integrated LED indicators and AutoMDIX functionality may introduce design considerations not present in the primary part.

Q: Do all substitute parts carry equivalent compliance certifications?

A: All listed parts carry ROHS3 or RoHS compliance certification, REACH unaffected status, and ECCN EAR99 classification. MSL ratings are uniform at Level 1 (unlimited) across all parts. Compliance documentation should be verified with individual manufacturers for specific application requirements.
