Engineering Selection Recommendations

All listed substitute parts are classified as active products with current manufacturing status, ensuring long-term availability and supply chain continuity. The primary distinction between the main part and substitutes is product status: the 75160-318-03 is obsolete, while all alternatives maintain active production.

RoHS Compliance Consideration: The original 75160-318-03 is RoHS non-compliant. All substitute parts listed are ROHS3 compliant, meeting current environmental and regulatory requirements for new designs and procurement.

Molex KK254 Series (0423752487, 0423752522): Both parts offer board-to-board or cable compatibility with gold-plated mating contacts and tin-plated posts. The 0423752522 provides higher gold plating thickness (30.0µin versus 15.0µin), offering enhanced contact durability. Both maintain UL94 V-0 flammability rating and unlimited moisture sensitivity.

Mill-Max 800 Series (800-10-003-10-001000): Features circular contact geometry with brass alloy material and gold plating on both mating and post surfaces. Insulation height is 0.110" (2.79mm), slightly higher than the original. This part offers board-to-board style only without cable compatibility.

Samtec MTLW Series (MTLW-103-07-G-S-230): Provides the lowest insulation height at 0.060" (1.52mm) with liquid crystal polymer insulation and operating temperature range of -55°C to 125°C. Current rating is specified at 5.2A per contact. MSL is not applicable, indicating superior moisture resistance.

Samtec TS Series (TS-103-G-A-1, TS-103-G-AA, TS-103-T-A-1): Simplified header designs without push-pull fastening specification. TS-103-G-A-1 and TS-103-G-AA feature gold plating with 20.0µin thickness, while TS-103-T-A-1 uses tin plating at 200.0µin thickness. These parts are suitable for applications where fastening type is not critical.

Samtec TSW Series (TSW-103-07-L-S, TSW-103-07-S-S, TSW-103-08-T-S): All TSW variants maintain board-to-board or cable compatibility with push-pull fastening. TSW-103-07-L-S and TSW-103-07-S-S feature gold-plated mating contacts with tin-plated posts, operating temperature -55°C to 125°C. TSW-103-08-T-S uses tin plating on both surfaces with extended post length (0.200" versus 0.100") and operating temperature range of -55°C to 105°C.

Frequently Asked Questions (FAQ)

Q: Can the 75160-318-03 be directly replaced with any of these substitute parts?

A: Yes, all listed parts meet the critical substitution criteria: 3-position, 0.100" (2.54mm) pitch, through-hole solder termination, unshrouded male pin headers. Physical and electrical compatibility is maintained across all alternatives. However, verify PCB footprint dimensions and contact length requirements for your specific application, as minor variations exist in overall contact length (0.430" to 0.530") and insulation height (0.060" to 0.110").

Q: What is the primary advantage of switching from the obsolete 75160-318-03 to an active substitute?

A: Active products ensure continuous manufacturing, stable pricing, and reliable supply chain availability. The 75160-318-03 is obsolete, meaning production has ended and inventory is limited. All substitute parts are actively manufactured, providing long-term design support and procurement security.

Q: Are there RoHS compliance differences between the main part and substitutes?

A: Yes. The 75160-318-03 is RoHS non-compliant, while all substitute parts are ROHS3 compliant. For new designs or applications subject to environmental regulations, ROHS3-compliant substitutes are required.

Q: What contact finish options are available?

A: Substitutes offer three contact finish options: tin-lead (original only), gold, or tin. Gold-plated contacts (Molex, Samtec MTLW, Samtec TS-103-G variants, Samtec TSW-103-07 variants) provide superior corrosion resistance and lower contact resistance. Tin-plated contacts (Samtec TS-103-T-A-1, Samtec TSW-103-08-T-S) offer cost efficiency. Select based on environmental exposure and reliability requirements.

Q: Do all substitutes support push-pull fastening?

A: Most substitutes support push-pull fastening (Molex, Mill-Max, Samtec MTLW, Samtec TSW series). Samtec TS series parts do not specify fastening type, indicating they are designed for applications where mechanical fastening is not required. Verify fastening requirements for your application before selection.

Q: What is the difference between board-to-board and board-to-board/cable compatible styles?

A: Board-to-board style (Mill-Max 800 series, original 75160-318-03) is designed for direct PCB-to-PCB mating. Board-to-board or cable compatible style (Molex KK254, Samtec MTLW, Samtec TSW) accommodates both PCB mating and cable connector attachment, providing design flexibility.

Q: Are there operating temperature differences among substitutes?

A: Yes. Most substitutes operate from -55°C to 125°C. Samtec TSW-103-08-T-S has a narrower range of -55°C to 105°C. Samtec MTLW-103-07-G-S-230 specifies -55°C to 125°C with additional current rating of 5.2A per contact. Verify temperature requirements for your application environment.

Q: What insulation materials are used in substitute parts?

A: Insulation materials vary: Polyamide (PA) nylon glass-filled (Molex), Polycyclohexylenedimethylene Terephthalate/PCT (Mill-Max), Liquid Crystal Polymer/LCP (Samtec MTLW), and Polybutylene Terephthalate/PBT (Samtec TSW). All materials meet UL94 V-0 flammability requirements. Material selection affects mechanical properties and temperature performance.

Q: How do contact length variations affect compatibility?

A: Overall contact length ranges from 0.430" to 0.530". Longer contacts (TSW-103-08-T-S at 0.530") provide deeper PCB penetration, suitable for thicker boards or applications requiring maximum mechanical engagement. Shorter contacts (MTLW-103-07-G-S-230 at 0.430") are appropriate for standard PCB thicknesses. Verify PCB thickness and hole depth for your design.

Q: What is the inventory status of these substitute parts?

A: All substitute parts are in active stock with quantities ranging from 75 to 92,800 pieces, ensuring immediate availability. The original 75160-318-03 has 692 pieces in stock but is obsolete, making substitutes the recommended choice for new procurement.
