Engineering Selection Recommendations

Direct Substitution (5499374-9): The part 5499374-9 is a direct substitute for 499374-9 with identical electrical and mechanical specifications. This part is RoHS Compliant and REACH Unaffected, providing regulatory advantages over the main part. The contact post finish is Tin instead of Tin-Lead, which aligns with modern lead-free soldering requirements. Selection of 5499374-9 is appropriate when RoHS compliance is a design requirement.

Cross-Manufacturer Equivalents: HARTING SEK series parts (09185406914, 09185407904) are functionally equivalent rectangular connectors with identical pitch, position count, and mounting characteristics. These parts feature extended operating temperature range (-55°C ~ 125°C) compared to the main part (-65°C ~ 105°C). Insulation height differences (0.681" versus 0.549") indicate mechanical design variations that require board layout verification.

Amphenol ICC/FCI 71918-240LF (Quickie™ series) maintains core electrical compatibility with 0.100" (2.54mm) pitch and 40-position configuration. This part features GXT™ gold mating surface finish and operates at unspecified temperature and voltage ratings.

3M 3000 series parts (N3432-6202RB, N3432-6203RB) provide functional equivalence with higher current rating (1.75A per contact) and operating temperature range (-55°C ~ 105°C). These parts are RoHS Compliant and suitable for applications requiring enhanced current capacity.

All substitute parts maintain UL94 V-0 flammability rating and MSL 1 moisture sensitivity classification, ensuring compatibility with standard PCB assembly processes.

Frequently Asked Questions (FAQ)

Q: Can 5499374-9 be used as a direct replacement for 499374-9?

A: Yes. The 5499374-9 maintains identical electrical and mechanical specifications including pitch, position count, contact dimensions, and operating temperature range. The primary differences are packaging format (Tray versus Bulk) and regulatory compliance status (RoHS Compliant versus RoHS non-compliant). The contact post finish is Tin instead of Tin-Lead, which is compatible with standard solder processes.

Q: What are the key differences between TE Connectivity 499374-9 and HARTING SEK series equivalents?

A: HARTING SEK series parts (09185406914, 09185407904) share identical pitch (0.100"), position count (40), and mounting type (through-hole solder). Mechanical differences include increased insulation height (0.681" versus 0.549") and extended operating temperature range (-55°C ~ 125°C versus -65°C ~ 105°C). Contact length dimensions vary between parts, requiring verification of mechanical fit in specific board designs.

Q: Are HARTING and 3M parts suitable replacements for applications requiring 250VAC rating?

A: HARTING SEK series and Amphenol ICC/FCI 71918-240LF do not specify voltage ratings in their technical data. The 3M 3000 series parts also do not specify voltage ratings. If 250VAC rating is a critical design requirement, the main part 499374-9 or direct substitute 5499374-9 should be selected, as these parts explicitly specify 250VAC voltage rating.

Q: What is the difference between packaging formats (Bulk, Tray, Tube)?

A: Packaging format affects quantity per container and handling characteristics but does not alter electrical or mechanical specifications. Bulk packaging contains loose components, Tray packaging provides organized component arrangement, and Tube packaging offers compact storage. Selection depends on assembly process requirements and inventory management practices.

Q: Can parts with different contact post lengths be interchanged?

A: Contact post length affects solder joint formation and mechanical engagement with mating connectors. The main part 499374-9 specifies 0.155" (3.94mm) post length, while HARTING SEK series parts specify 0.114" (2.90mm). Substitution requires verification that PCB pad design and mating connector specifications accommodate the different post length to ensure reliable solder connections.

Q: Which substitute parts are RoHS Compliant?

A: The following parts are RoHS Compliant: 5499374-9 (RoHS Compliant), 09185406914 (ROHS3 Compliant), 09185407904 (ROHS3 Compliant), 71918-240LF (RoHS Compliant), N3432-6202RB (RoHS Compliant), and N3432-6203RB (RoHS Compliant). The main part 499374-9 is RoHS non-compliant. Selection of RoHS Compliant alternatives is required for applications subject to RoHS directive requirements.

Q: What current rating should be considered when selecting a substitute?

A: The main part 499374-9 specifies 1A per contact. The 3M 3000 series parts (N3432-6202RB, N3432-6203RB) specify 1.75A per contact, providing higher current capacity. HARTING SEK series and Amphenol ICC/FCI 71918-240LF do not specify current ratings. For applications requiring current ratings above 1A per contact, the 3M parts are suitable alternatives.

Q: Are all substitute parts available in the same packaging options?

A: No. The main part 499374-9 is available in Bulk packaging. The 5499374-9 direct substitute is available in Tray packaging. HARTING parts are available in Bulk or Tray formats depending on specific part number. Amphenol ICC/FCI 71918-240LF is available in Tube packaging. 3M parts are available in Bulk packaging. Packaging availability should be verified with supplier inventory before component selection.
