Engineering Selection Recommendations

Primary Recommendation: 75869-303LF

The Amphenol ICC 75869-303LF is the direct equivalent of the obsolete 75869-303. It maintains identical electrical and mechanical specifications while achieving RoHS compliance. This part is manufactured by the same supplier using the same series platform (Quickie™) and is the preferred choice for direct replacement in existing designs.

Secondary Recommendations: TE Connectivity AMP-Latch Series (1761681-6 or 2-1761603-6)

The TE Connectivity 1761681-6 and 2-1761603-6 connectors provide active-status alternatives with RoHS compliance. Both employ push-pull fastening identical to the original design. The 1761681-6 uses Polycyclohexylenedimethylene Terephthalate (PCT) insulation material, while the 2-1761603-6 uses Polybutylene Terephthalate (PBT). Both support extended operating temperature ranges (-65°C to 105°C) and carry electrical ratings of 1A per contact at 250VAC.

Alternative Recommendations: HARTING SEK Series (09185165324, 09185166324, 09185167324, 09195166324, 09195167324)

The HARTING SEK series connectors meet all critical dimensional and electrical parameters. These parts employ latch holder fastening rather than push-pull mechanisms. The 09185165324, 09185166324, and 09185167324 variants specify gold mating contact finish, while 09195166324 and 09195167324 do not specify mating contact finish. All HARTING variants support -55°C to 125°C operating temperature range and carry ROHS3 compliance.

Alternative Recommendation: Assmann WSW AWHW 16G-0202-T

The Assmann WSW AWHW 16G-0202-T connector maintains push-pull fastening and meets dimensional requirements. This part uses brass contact material and supports -40°C to 105°C operating temperature with 3A current rating per contact. ROHS3 compliance is confirmed.

All recommended substitutes maintain UL94 V-0 flammability rating and MSL 1 (Unlimited) moisture sensitivity classification.

Frequently Asked Questions (FAQ)

Q: Can the 75869-303LF be used as a direct replacement for the 75869-303?

A: Yes. The 75869-303LF is the active-status equivalent manufactured by Amphenol ICC. It maintains identical connector type, position count, pitch, shrouding, mounting method, and termination. The primary difference is RoHS compliance status. No design modifications are required.

Q: What is the difference between push-pull and latch holder fastening types?

A: Push-pull fastening uses a simple push-to-connect, pull-to-disconnect mechanism. Latch holder fastening employs mechanical latches for connection retention. Both fastening types are mechanically and electrically compatible with standard mating connectors designed for 0.100" (2.54mm) pitch headers. Selection depends on application-specific requirements for connection security and ease of assembly.

Q: Are HARTING SEK series connectors compatible with the original 75869-303 design?

A: Yes. HARTING SEK series connectors (09185165324, 09185166324, 09185167324, 09195166324, 09195167324) meet all critical parameters: 16 positions, 2 rows, 0.100" pitch, shrouded 4-wall construction, through-hole mounting, and solder termination. The primary difference is fastening type (latch holder versus push-pull). Mechanical and electrical compatibility is maintained.

Q: What packaging options are available for substitute parts?

A: The 75869-303LF is supplied in tube packaging. HARTING SEK series parts are available in bulk (09185165324, 09195166324, 09195167324) or tray (09185166324, 09185167324) packaging. TE Connectivity AMP-Latch series parts are supplied in bulk packaging. Assmann WSW AWHW 16G-0202-T is supplied in tray packaging. Packaging selection does not affect electrical or mechanical performance.

Q: Are all substitute parts RoHS compliant?

A: The original 75869-303 is RoHS non-compliant. All recommended substitutes are RoHS compliant: 75869-303LF (RoHS Compliant), HARTING SEK series (ROHS3 Compliant), TE Connectivity AMP-Latch series (RoHS Compliant), and Assmann WSW AWHW 16G-0202-T (ROHS3 Compliant).

Q: What is the operating temperature range for each substitute part?

A: The original 75869-303 does not specify operating temperature. Substitute parts support the following ranges: 75869-303LF (not specified), HARTING SEK series (-55°C to 125°C), TE Connectivity AMP-Latch series (-65°C to 105°C), and Assmann WSW AWHW 16G-0202-T (-40°C to 105°C). Design requirements should determine the appropriate selection.

Q: Can contact material differences affect performance?

A: Contact material differences (phosphor bronze versus copper alloy versus brass) do not affect compatibility with standard mating connectors. All materials specified in substitute parts maintain electrical conductivity and mechanical durability within the 0.100" (2.54mm) pitch header application envelope. Material selection reflects manufacturing process and cost considerations rather than functional performance differences.

Q: What is the significance of contact finish thickness specifications?

A: Contact finish thickness (measured in microinches or micrometers) indicates gold plating depth on mating contacts. Thicker finishes provide extended contact life under repeated mating cycles. The original 75869-303 specifies 15.0µin (0.38µm) gold thickness. Substitute parts specify 15.0µin to 30.0µin mating contact finish thickness. All specified thicknesses are within acceptable ranges for 0.100" pitch header applications.
