Engineering Selection Recommendations

All listed substitute parts are manufactured by Amphenol ICC (FCI) and maintain active product status, ensuring long-term availability and supply chain continuity. The substitute parts exceed the electrical specifications of the original 3M component, with current ratings of 2A (AC/DC) and voltage ratings of 200V (AC/DC) compared to the original 1A rating.

For applications requiring RoHS compliance, select from the following active parts: 57202-F52-03LF, 57202-G52-03LF, 57202-G52-03TRLF, 57202-S52-03LF, or 91753-007TRLF. The part 57202-G52-03A is RoHS non-compliant and should be used only in applications where RoHS compliance is not required.

Packaging selection depends on production volume and assembly requirements. Tape & Reel (TR) packaging (57202-G52-03A, 57202-G52-03TRLF, 91753-007TRLF) is suitable for automated pick-and-place assembly. Box packaging (57202-F52-03LF, 57202-S52-03LF) is appropriate for manual assembly or lower-volume applications. Bulk packaging (57202-G52-03LF) offers flexibility for mixed-volume production runs.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol ICC (FCI) Minitek® 2.00mm series parts directly replace the 3M 951206-2520-AR-TP?

A: Yes. All listed substitute parts maintain electrical and mechanical equivalence across critical parameters including connector type, contact configuration, pitch, mounting type, and fastening mechanism. The parts are functionally interchangeable in board-to-board applications.

Q: What is the difference between the various Amphenol ICC (FCI) substitute part numbers?

A: The differences are limited to packaging format and contact finish specifications. The 57202-F52-03LF, 57202-G52-03A, 57202-G52-03LF, 57202-G52-03TRLF, and 57202-S52-03LF variants differ in packaging (Box, Tape & Reel, or Bulk) and contact finish thickness. The 91753-007TRLF offers board-to-board or cable style flexibility. All maintain the same core electrical and mechanical specifications.

Q: Are there compliance differences between the substitute parts?

A: Yes. The 57202-G52-03A is RoHS non-compliant, while 57202-F52-03LF, 57202-G52-03LF, 57202-G52-03TRLF, 57202-S52-03LF, and 91753-007TRLF are RoHS compliant. Additionally, 57202-G52-03LF, 57202-G52-03TRLF, 57202-S52-03LF, and 91753-007TRLF carry REACH Affected status where applicable. Select based on your application's regulatory requirements.

Q: How do the current and voltage ratings of the substitutes compare to the original part?

A: The substitute parts are rated for 2A (AC/DC) and 200V (AC/DC), exceeding the original 3M part's 1A rating. This higher rating provides additional design margin and is fully backward compatible with applications designed for the original 1A specification.

Q: Which substitute part should I select for automated assembly?

A: For automated pick-and-place assembly, select parts packaged in Tape & Reel (TR) format: 57202-G52-03A, 57202-G52-03TRLF, or 91753-007TRLF. These parts are specifically designed with pick-and-place features for high-volume production.

Q: Is the insulation color difference between parts significant?

A: The 91753-007TRLF features natural insulation color, while all other substitutes have black insulation. This is a cosmetic difference and does not affect electrical or mechanical performance. Select based on visual identification requirements or assembly documentation standards.
