Substitute Part Grouping Explanation

Substitution eligibility for the 53611-S20-4LF is determined by strict alignment of the following core parameters: connector type (header), contact type (male pin), number of positions (20), number of rows (2), mating pitch (0.100"/2.54mm), row spacing (0.100"/2.54mm), shrouding configuration (shrouded 4-wall), mounting method (through hole), termination type (solder), fastening mechanism (latch lock/eject hooks), contact shape (square), and flammability rating (UL94 V-0).

All identified substitute parts are manufactured by TE Connectivity AMP Connectors and belong to the AMP-Latch series. These parts maintain identical electrical and mechanical interface parameters with the original Amphenol ICC part. Variations in contact length specifications, insulation height, contact finish thickness, operating temperature range, current rating, voltage rating, RoHS compliance status, and packaging format do not preclude substitution when the core mating and mounting parameters remain constant.

Frequently Asked Questions (FAQ)

Q: Can 53611-S20-4LF be directly replaced with any TE Connectivity AMP-Latch substitute?

A: Yes. All listed substitute parts maintain identical mating pitch (0.100"/2.54mm), row spacing (0.100"/2.54mm), position count (20 in 2 rows), shrouding configuration (4-wall), mounting method (through hole), and termination type (solder). Direct mechanical and electrical interface compatibility is established.

Q: What are the differences in contact length specifications?

A: The original 53611-S20-4LF specifies contact length - mating at 0.230" (5.84mm) and contact length - post at 0.120" (3.05mm). TE Connectivity substitutes specify contact length - mating at 0.240" (6.10mm) with post lengths varying between 0.110" (2.79mm) and 0.155" (3.94mm). These dimensional variations do not affect mating compatibility when board layout and connector cavity depth accommodate the specified tolerances.

Q: Are there RoHS compliance differences between substitutes?

A: Yes. Parts 2-5499206-4, 5102321-4, 5499206-4, and 5499922-4 are ROHS3 compliant. Parts 102321-4 and 499206-4 are RoHS non-compliant. The original 53611-S20-4LF is RoHS compliant. Selection depends on end-product regulatory requirements.

Q: What is the difference between tray and bulk packaging?

A: Part 5499922-4 is supplied in bulk packaging format, while all other substitutes are supplied in tray packaging. Bulk packaging typically accommodates higher volume orders and may offer cost advantages for large-scale production. Tray packaging is standard for component handling and storage.

Q: Does insulation color affect substitution eligibility?

A: Insulation color is a visual identifier and does not affect electrical or mechanical compatibility. The original part and most substitutes feature black insulation. Part 2-5499206-4 features blue insulation. Color selection may be driven by internal assembly documentation or visual identification requirements.

Q: What is the significance of contact finish differences?

A: The original 53611-S20-4LF specifies gold or gold GXT™ mating finish with 15.0µin (0.38µm) thickness and tin post finish with 100.0µin (2.54µm) thickness. TE Connectivity substitutes specify gold or gold-palladium mating finish with 15.0µin to 30.0µin thickness and tin or tin-lead post finish with 100.0µin thickness. These finishes provide equivalent corrosion resistance and electrical performance for standard applications.

Q: Are operating temperature ranges specified for the original part?

A: Operating temperature is not specified for the original 53611-S20-4LF. All TE Connectivity substitutes specify -65°C to 105°C operating temperature range. Applications requiring temperature specification should reference the substitute part data.

Q: What inventory levels are available for each substitute?

A: Part 5499206-4 offers the highest availability at 500,200 units. Part 5499922-4 provides 62,300 units in bulk format. Parts 5102321-4, 2-5499206-4, 102321-4, and 499206-4 provide 5061, 1963, 1047, and 911 units respectively in tray packaging.
