Frequently Asked Questions (FAQ)

Q: Can the 5499374-8 be used as a direct replacement for the 499374-8?

A: Yes. The 5499374-8 is a direct electrical and mechanical equivalent. Both parts feature 34 positions, 2.54mm pitch, through-hole solder termination, and identical contact specifications. The primary difference is packaging format (Bulk) and compliance status (ROHS3 compliant versus RoHS non-compliant). Selection depends on compliance requirements for your application.

Q: What are the key differences between TE Connectivity and HARTING variants?

A: The HARTING SEK series (09185347914, 09185346914, 09195347904) maintains all critical electrical and mechanical parameters but introduces dimensional variations in contact length and insulation height. HARTING parts feature extended operating temperature to 125°C and achieve ROHS3 compliance. Contact mating length is 0.228" (5.80mm) versus 0.240" (6.10mm) on TE parts, and post length is 0.114" (2.90mm) versus 0.155" (3.94mm). These dimensional differences may affect board layout and mating interface design.

Q: Are the 3M N3431-6202RB and N3431-6203RB interchangeable?

A: Both 3M parts are electrically and mechanically compatible with the 499374-8 and each other across all mandatory parameters. The primary difference is contact post length: N3431-6202RB features 0.112" (2.84mm) post length, while N3431-6203RB features 0.155" (3.94mm) post length. Selection depends on your specific board thickness and mating interface requirements. Both achieve ROHS3 compliance and provide 1.75A current capacity.

Q: What packaging options are available for these substitute parts?

A: Packaging formats vary by manufacturer and part number. The 5499374-8 is supplied in Bulk format. HARTING 09185347914 is supplied in Tray format. Amphenol 71918-234LF is supplied in Tube format. 3M N3431-6202RB and N3431-6203RB are supplied in Bulk format. 3M D3431-6202-AR is supplied in Tray format. Packaging selection affects handling, storage, and assembly processes.

Q: Do all substitute parts meet RoHS compliance requirements?

A: No. The original 499374-8 is RoHS non-compliant. The 5499374-8, HARTING SEK series, and 3M 3000 series all achieve ROHS3 compliance. The Amphenol 71918-234LF achieves RoHS compliance. For applications requiring RoHS3 compliance, select from the 5499374-8, HARTING variants, or 3M variants.

Q: What is the impact of contact finish differences on connector performance?

A: All substitute parts feature gold mating contact finish with tin post finish, maintaining electrical performance equivalent to the 499374-8. The 499374-8 specifies Gold or Gold-Palladium mating finish with Tin-Lead post finish. The 5499374-8 changes post finish to Tin. HARTING and Amphenol parts use standard Gold and Tin finishes. 3M parts use Gold and Tin finishes. These variations do not affect electrical compatibility but may influence corrosion resistance and long-term reliability in specific environmental conditions.

Q: Are there temperature rating differences between substitute parts?

A: Yes. The 499374-8 operates from -65°C to 105°C. The 5499374-8 maintains this range. HARTING SEK series extends to -55°C to 125°C, providing higher temperature capability. The 3M 3000 series operates from -55°C to 105°C. Amphenol 71918-234LF does not specify operating temperature. For applications requiring -65°C minimum temperature, use the 499374-8 or 5499374-8. For applications requiring 125°C maximum temperature, use HARTING variants.

Q: What current and voltage ratings apply to each substitute part?

A: The 499374-8 is rated for 1A per contact at 250VAC. The 5499374-8 maintains these ratings. The 3M 3000 series (N3431-6202RB, N3431-6203RB, D3431-6202-AR) provides 1.75A per contact, exceeding the original specification. HARTING SEK series and Amphenol 71918-234LF do not specify current or voltage ratings in available documentation. For applications requiring 250VAC operation, use TE Connectivity or 3M variants.

Q: How do insulation height variations affect board design?

A: The 499374-8 features 0.549" (13.94mm) insulation height. Substitute parts show variations: HARTING variants are 0.681" (17.30mm), Amphenol is 0.685" (17.40mm), and 3M variants are 0.680" (17.27mm). These dimensional differences affect clearance requirements above the connector on the PCB. Verify board layout compatibility before selecting substitute parts with different insulation heights.

Q: Which substitute part offers the highest inventory availability?

A: The 3M N3431-6202RB provides the highest inventory with 20,100 pieces in stock, followed by 3M N3431-6203RB with 2,010 pieces. The original 499374-8 has 1,166 pieces available. Amphenol 71918-234LF has 1,107 pieces. HARTING 09185347914 has 964 pieces. TE Connectivity 5499374-8 has 829 pieces. Inventory levels support supply chain planning and lead time management.
