Substitute Part Grouping Explanation

Substitution eligibility for the 7499111447 is determined by strict equivalence across the following critical parameters:

• Connector Type & Port Configuration: All substitutes must be single-port RJ45 connectors
• Electrical Performance: All substitutes must support 10/100/1000 Base-T with AutoMDIX functionality
• Physical Form Factor: All substitutes must feature 90° right-angle through-hole mounting with solder termination
• Shielding & EMI Protection: All substitutes must include shielding with EMI finger design
• Signal Integrity: All substitutes must provide 8-core jack configuration with gold-plated contacts
• Regulatory Compliance: All substitutes must maintain ROHS3 compliance and REACH unaffected status

The two qualified substitutes—0826-1C1T-43-F (Bel Fuse Inc.) and JD1-0002NL (Pulse Electronics)—meet these core electrical and mechanical requirements. Differences in contact material, shield material, housing composition, and operating temperature ranges do not affect functional equivalence for standard 10/100/1000 Base-T applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status and full regulatory compliance (ROHS3, REACH unaffected, EAR99 classification). Selection between the 7499111447 and its substitutes should be based on application-specific operating temperature requirements and packaging availability:

• 7499111447 (Würth Elektronik): Extended operating temperature range (-40°C to 85°C) suits industrial and automotive environments requiring wider thermal tolerance. Tube packaging supports smaller-volume procurement.

• 0826-1C1T-43-F (Bel Fuse Inc.): Standard operating range (0°C to 70°C) appropriate for commercial networking applications. Bulk packaging optimizes high-volume production. MagJack® series designation indicates integrated magnetic functionality.

• JD1-0002NL (Pulse Electronics): Standard operating range (0°C to 70°C) suitable for commercial applications. Tray packaging supports mid-volume assembly operations. PULSEJACK™ JD1 series provides highest inventory availability (2573 units in stock).

All three parts are electrically and mechanically equivalent for standard 10/100/1000 Base-T Ethernet applications. Physical height variations (14.65mm to 13.80mm) are within typical PCB layout tolerances for through-hole connectors.

Frequently Asked Questions (FAQ)

Q: Can 0826-1C1T-43-F replace 7499111447 in all applications?

A: Functional equivalence is confirmed for 10/100/1000 Base-T Ethernet applications within the 0°C to 70°C operating range. Applications requiring extended temperature operation below 0°C or above 70°C require the 7499111447 or equivalent parts with matching thermal specifications.

Q: What are the physical compatibility considerations?

A: All three parts feature 90° right-angle through-hole mounting with solder termination. Height above board varies between 14.65mm and 13.80mm. PCB layout and component clearance should be verified for designs with tight vertical spacing constraints.

Q: Are there differences in packaging that affect assembly?

A: Yes. The 7499111447 ships in tube packaging, 0826-1C1T-43-F in bulk, and JD1-0002NL in tray. Packaging selection impacts pick-and-place automation compatibility and inventory management. Confirm packaging compatibility with assembly equipment specifications.

Q: Do all substitutes provide identical LED functionality?

A: All three parts include dual-color LED indicators (green and yellow). LED behavior and signaling protocols are determined by the host device firmware and are not affected by connector manufacturer differences.

Q: What is the significance of contact material differences?

A: The 7499111447 uses tin contact material with 30.0µin gold finish. Substitutes use copper alloy (0826-1C1T-43-F) or phosphor bronze (JD1-0002NL) with varying gold finish thickness (50.0µin and 6.00µin respectively). All configurations provide adequate contact resistance and durability for standard Ethernet applications.

Q: Are there supply chain advantages to using substitutes?

A: Yes. JD1-0002NL offers the highest inventory availability (2573 units). 0826-1C1T-43-F provides mid-range stock (858 units). Substitute selection can optimize lead times and reduce supply chain risk for high-volume production.
