Key Parameters

Substitute Part Grouping Explanation

Substitution for the 77336-426LF is determined by strict equivalence across the following critical parameters:

• Connector Type: Receptacle (female socket contact type)
• Position Count: 26 positions
• Pitch and Row Configuration: 0.100" (2.54mm) pitch with 2-row arrangement and 0.100" row spacing
• Cable Termination Method: IDC (Insulation Displacement Contact)
• Contact Finish: Gold plating
• Mounting Configuration: Free Hanging (In-Line)
• Wire Type: Ribbon Cable compatibility

Substitute parts must maintain these electrical and mechanical parameters. Wire gauge specifications (28-30 AWG, 26-28 AWG) represent acceptable variations within IDC contact design tolerances and do not prevent functional substitution. Connector type variations (Receptacle vs. Header) indicate mating pair alternatives rather than direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: 71600-426LF (Amphenol ICC)

The 71600-426LF is the manufacturer-recommended direct replacement for the obsolete 77336-426LF. Both are Amphenol ICC products within the Quickie™ series, maintaining identical mechanical and electrical specifications. The 71600-426LF carries Active product status and RoHS Compliant certification, making it suitable for new designs and legacy system replacements.

Secondary Recommendations: 3M Series (3399-6000, 3399-G600, 3399-H600, 89126-0001)

The 3M rectangular receptacle connectors (3000 and 891 series) provide functionally equivalent alternatives with Active product status and ROHS3 Compliance. The 3399-G600 and 3399-H600 variants include polarizing key features and support both stranded and solid wire configurations. The 89126-0001 offers the highest current inventory availability (1863 units).

Alternative Options: HARTING SEK Series (09185266803, 09185267803)

The HARTING SEK series receptacles maintain full electrical and mechanical compatibility with polarizing key features and ROHS3 Compliance. These connectors are suitable for applications requiring enhanced keying mechanisms.

Connector Type Consideration: Sullins SFH Series (Headers)

The Sullins SFH210-PPPC-D13-ID-BK-M181 and SFH213-PPPC-D13-ID-BK-M181 are header connectors (not receptacles) and represent mating pair alternatives rather than direct substitutes. These are appropriate only when the application requires a header connector instead of a receptacle.

Frequently Asked Questions (FAQ)

Q: Can the 71600-426LF directly replace the 77336-426LF?

A: Yes. The 71600-426LF is the manufacturer-recommended replacement. Both connectors share identical pitch (0.100"), position count (26), row configuration (2 rows at 0.100" spacing), IDC termination, gold contact finish, and free-hanging mounting. The primary difference is product status: 77336-426LF is obsolete while 71600-426LF is active.

Q: What is the significance of wire gauge differences (28-30 AWG vs. 26-28 AWG)?

A: Wire gauge specifications indicate the range of ribbon cable sizes the IDC contacts can accommodate. These variations do not prevent functional substitution. The 77336-426LF does not specify wire gauge, indicating compatibility across the standard range. Substitute parts with specified wire gauges (28-30 AWG or 26-28 AWG) are all acceptable for ribbon cable applications within those ranges.

Q: Are HARTING and 3M connectors compatible with Amphenol ICC designs?

A: Yes, provided the mechanical and electrical parameters match. The HARTING 09185266803, 09185267803 and 3M 3399-6000, 3399-G600, 3399-H600, and 89126-0001 all maintain the required 26-position, 0.100" pitch, 2-row configuration with 0.100" row spacing, IDC termination, and gold contact finish. These are direct functional equivalents.

Q: What is the difference between receptacle and header connectors?

A: Receptacle connectors (77336-426LF and all listed substitutes except Sullins SFH series) accept mating plugs or headers. Header connectors (Sullins SFH210 and SFH213) are mounted on circuit boards and mate with receptacles or cables. The Sullins SFH series are not direct substitutes for the 77336-426LF receptacle; they are complementary mating components.

Q: Do polarizing key features affect substitution compatibility?

A: Polarizing keys are additional mechanical features that prevent incorrect mating orientation. The 77336-426LF does not include a polarizing key. Substitute parts with polarizing keys (HARTING SEK series, 3M 3399-G600, 3399-H600) are mechanically compatible but add keying functionality. Parts without polarizing keys (3M 3399-6000, 89126-0001, Amphenol ICC 71600-426LF) maintain the original design approach.

Q: Which substitute offers the best compliance for new designs?

A: All active substitute parts listed meet current regulatory requirements. The 71600-426LF (Amphenol ICC) is RoHS Compliant. The HARTING SEK series, 3M 3399-G600, 3399-H600, and 89126-0001 are ROHS3 Compliant. For new designs, ROHS3 Compliant options (HARTING, 3M 3399-G600/H600, 89126-0001) represent the most current compliance standard.

Q: What packaging options are available?

A: Substitute parts are available in multiple packaging formats: Tube (71600-426LF), Bulk (HARTING, 3M 3399 series, 89126-0001), and Tray (Sullins SFH series). Packaging selection depends on procurement volume and handling requirements but does not affect electrical or mechanical compatibility.
