Substitute parts are grouped into two categories:

Category 1: Direct Amphenol ICC Equivalent The 53611-G34-4LF is the active production equivalent from the same manufacturer and series (Quickie™). This part maintains identical mechanical and electrical specifications while offering RoHS compliance and improved availability.

Category 2: TE Connectivity AMP-Latch Series Substitutes Parts from TE Connectivity (102321-8, 2-5499206-8, 499206-8, 499922-8, 5102321-8, 5499206-8, 5499922-8, 5499923-8) are functionally equivalent across all critical parameters. These parts share the same pitch, position count, shrouding, and termination method. Variations exist in contact length specifications, post finish materials, and compliance certifications, but all maintain board-to-cable/wire connection capability with identical mating interfaces.

Category 3: Assmann WSW Components Alternative The AWH 34G-0222-T provides mechanical and electrical equivalence with differences in contact material (brass vs. phosphor bronze), insulation material composition, and operating temperature range.

Engineering Selection Recommendations

For applications currently using the obsolete 53611-G34-4, the following selection criteria apply:

Primary Recommendation: 53611-G34-4LF This Amphenol ICC part is the direct active production equivalent. It maintains identical mechanical and electrical specifications while offering RoHS compliance and superior availability. This is the preferred choice for new designs and direct replacements where the original series continuity is required.

Secondary Recommendation: TE Connectivity AMP-Latch Series (5499206-8, 5499922-8, 5499923-8) These parts provide full functional equivalence with active product status and ROHS3 compliance. The 5499206-8 offers the highest inventory availability (10,100 units) and is suitable for applications where manufacturer diversity is acceptable. The 5499922-8 and 5499923-8 provide alternative contact finish thickness options (15.0µin mating finish) for specific environmental requirements.

Tertiary Recommendation: TE Connectivity 102321-8 and 5102321-8 These parts are suitable for applications requiring longer contact post lengths (0.155" / 3.94mm). Both maintain full electrical and mechanical compatibility with identical pitch and position specifications.

Alternative Consideration: Assmann WSW AWH 34G-0222-T This part provides the highest current rating (3A) and extended operating temperature range (-40°C to 105°C). It is suitable for applications with higher thermal or current demands. Note the differences in contact material (brass vs. phosphor bronze) and insulation material composition (glass-filled PBT vs. thermoplastic).

Compliance Considerations: For new designs requiring RoHS compliance, select from: 53611-G34-4LF, 2-5499206-8, 5102321-8, 5499206-8, 5499922-8, 5499923-8, or AWH 34G-0222-T. For REACH-unaffected applications, prioritize 2-5499206-8, 5102321-8, 5499206-8, 5499922-8, 5499923-8, or AWH 34G-0222-T.

Frequently Asked Questions (FAQ)

Q: Can I directly replace 53611-G34-4 with 53611-G34-4LF? A: Yes. The 53611-G34-4LF is the active production equivalent from Amphenol ICC. It maintains identical pitch (0.100"), position count (34), row configuration (2 rows), shrouding (4-wall), and termination method (solder). The primary difference is RoHS compliance status and improved availability.

Q: Are TE Connectivity AMP-Latch parts fully compatible with the original Amphenol ICC connector? A: Yes, for mating interface purposes. All TE Connectivity substitutes share identical pitch (0.100"), position count (34), row spacing (0.100"), shrouding (4-wall), and contact type (male pin). Variations in contact post length and insulation height do not affect mating compatibility but may impact PCB layout and mechanical clearance. Verify board-level dimensions before implementation.

Q: What is the difference between contact post lengths in the substitute parts? A: Contact post length varies between 0.110" (2.79mm), 0.120" (3.05mm), and 0.155" (3.94mm) across the substitute options. Longer posts provide greater engagement depth with mating receptacles and accommodate thicker PCB assemblies. Shorter posts reduce overall connector height. Select based on your specific PCB thickness and mating receptacle design.

Q: Which substitute part has the best availability? A: The TE Connectivity 5499206-8 has the highest inventory (10,100 units). The 5499922-8 and 5499923-8 also offer strong availability (1,684 and 1,694 units respectively). The Assmann WSW AWH 34G-0222-T provides 12,910 units in stock.

Q: Are there RoHS compliance differences between substitutes? A: Yes. The 53611-G34-4LF, 2-5499206-8, 5102321-8, 5499206-8, 5499922-8, 5499923-8, and AWH 34G-0222-T are RoHS3 compliant or RoHS compliant. The original 53611-G34-4, 102321-8, 499922-8, and 499206-8 are either non-compliant or not applicable. For new designs, select from the compliant options.

Q: What packaging options are available? A: Tray packaging is standard for most substitutes (53611-G34-4LF, 2-5499206-8, 499206-8, 499922-8, 5102321-8, 5499206-8, AWH 34G-0222-T). Bulk packaging is available for 102321-8, 5499922-8, and 5499923-8. Select based on your procurement and handling requirements.

Q: Can I use the Assmann WSW AWH 34G-0222-T as a direct substitute? A: The AWH 34G-0222-T is mechanically and electrically equivalent for mating interface purposes. However, note the differences: brass contact material (vs. phosphor bronze), glass-filled PBT insulation (vs. thermoplastic), higher current rating (3A vs. 1A), and extended operating temperature range (-40°C to 105°C vs. unspecified). These differences may affect performance in specific applications. Verify compatibility with your system requirements before implementation.

Q: What is the difference between tin and tin-lead post finishes? A: Tin-lead post finishes are found on 102321-8, 499206-8, and 499922-8. Tin post finishes are used on 53611-G34-4LF, 2-5499206-8, 5102321-8, 5499206-8, 5499922-8, 5499923-8, and AWH 34G-0222-T. Tin-lead finishes are restricted in RoHS3 compliant applications. For new designs, select tin-finished parts to ensure regulatory compliance.

Q: Do all substitutes have the same mating contact finish? A: All substitutes use gold or gold-based finishes on mating contacts. The original 53611-G34-4 and 53611-G34-4LF specify gold or gold GXT™. TE Connectivity parts specify gold or gold-palladium. Assmann WSW specifies gold with flash thickness. These variations are within acceptable industry standards for connector mating surfaces.
