Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 3M 951232-2520-AR-TP is determined by the following critical parameters:

Primary Matching Criteria:

• Connector Type: Header
• Contact Type: Male Pin
• Number of Positions: 32
• Number of Rows: 2
• Pitch - Mating: 0.079" (2.00mm)
• Row Spacing - Mating: 0.079" (2.00mm)
• Mounting Type: Surface Mount
• Style: Board to Board
• Fastening Type: Push-Pull
• Contact Finish - Mating: Gold
• Contact Material: Copper Alloy
• Insulation Material: Thermoplastic
• Material Flammability Rating: UL94 V-0

Acceptable Variation Parameters:

• Current Rating: Substitute parts rated at 2A (AC/DC) exceed the original 1A requirement and are acceptable
• Voltage Rating: Substitute parts rated at 200V (AC/DC) provide additional capability
• Operating Temperature: Substitute parts with extended temperature ranges (-55°C ~ 125°C) are acceptable
• Contact Finish Thickness - Mating: Variations in gold plating thickness (Flash, 30.0µin, 15.0µin) are acceptable provided gold finish is present
• Contact Finish Thickness - Post: Variations in tin plating thickness are acceptable
• Insulation Color: All substitutes maintain black insulation
• Packaging: Box, Bulk, or Tube packaging formats are interchangeable based on application requirements

All four substitute parts from Amphenol ICC (FCI) and Samtec Inc. meet these criteria and are classified as active products with current manufacturing support.

Parameter Comparison

Engineering Selection Recommendations

Amphenol ICC (FCI) Minitek® 2.00mm Series (57202-F52-16LF, 57202-G52-16LF, 57202-S52-16LF, 57202-S52-16ULF)

All four Amphenol ICC variants are active products with full manufacturing support and RoHS compliance certification. These connectors provide enhanced electrical performance with 2A current rating and 200V voltage rating compared to the original 1A specification. The Minitek® series maintains identical mechanical and electrical interface compatibility with the 3M 951232-2520-AR-TP.

Selection among the four Amphenol variants depends on packaging requirements:

• 57202-F52-16LF: Box packaging
• 57202-G52-16LF: Bulk packaging
• 57202-S52-16LF: Box packaging with GXT™ contact finish
• 57202-S52-16ULF: Tube packaging with GXT™ contact finish

Samtec TMMH-116-01-L-DV-M-TR

The Samtec TMMH series is an active product with ROHS3 compliance and extended operating temperature range (-55°C ~ 125°C). This connector features a cuttable header design and Liquid Crystal Polymer (LCP) insulation material. The contact length for mating is 0.126" (3.20mm) compared to 0.157" (4.00mm) in the original part. This variant is suitable for applications requiring lower profile or extended temperature operation.

Frequently Asked Questions (FAQ)

Q: Can I use the Amphenol 57202-F52-16LF as a direct replacement for the 3M 951232-2520-AR-TP?

A: Yes. The 57202-F52-16LF maintains identical pitch (0.079" / 2.00mm), row spacing, number of positions (32 in 2 rows), contact type (male pin), mounting type (surface mount), and fastening mechanism (push-pull). Both connectors feature gold-plated copper alloy contacts with thermoplastic insulation rated UL94 V-0. The Amphenol part provides enhanced electrical performance with 2A current rating and 200V voltage rating.

Q: What is the difference between the four Amphenol substitute parts?

A: The four Amphenol variants (57202-F52-16LF, 57202-G52-16LF, 57202-S52-16LF, 57202-S52-16ULF) are electrically and mechanically identical. Differences are limited to packaging format (Box, Bulk, or Tube) and contact finish thickness specifications. The GXT™ designation on 57202-G52-16LF and 57202-S52-16LF indicates enhanced gold plating technology. Selection should be based on procurement and assembly requirements.

Q: Why does the Samtec TMMH-116-01-L-DV-M-TR have a shorter contact length?

A: The Samtec TMMH series is designed as a low-profile connector with 0.126" (3.20mm) mating contact length compared to 0.157" (4.00mm) in the original 3M part. This design accommodates applications with space constraints while maintaining the same pitch and row spacing. The shorter contact length does not affect electrical compatibility with standard 2.00mm pitch receptacles.

Q: Are all substitute parts RoHS compliant?

A: Yes. All four Amphenol ICC variants are RoHS Compliant. The Samtec TMMH-116-01-L-DV-M-TR is ROHS3 Compliant. The original 3M 951232-2520-AR-TP RoHS status is not specified in the available data.

Q: What is the difference between standard gold plating and GXT™ plating?

A: GXT™ is Amphenol's enhanced gold plating technology. The contact finish thickness varies: standard gold flash plating, GXT™ at 30.0µin (0.76µm), and GXT™ at 15.0µin (0.38µm). All variants provide gold mating surface finish suitable for the 2.00mm pitch connector interface. Selection depends on specific application requirements for contact durability and wear resistance.

Q: Can I mix packaging formats when ordering substitute parts?

A: Yes. The electrical and mechanical specifications are identical across all packaging formats. Box, Bulk, and Tube packaging are interchangeable from a functional standpoint. Packaging selection should align with your assembly process and inventory management requirements.

Q: What is the operating temperature range for the Amphenol substitutes?

A: Operating temperature specifications are not provided in the available data for the Amphenol 57202 series. The original 3M 951232-2520-AR-TP operates from -25°C to 105°C. The Samtec TMMH-116-01-L-DV-M-TR operates from -55°C to 125°C, providing extended temperature capability for demanding applications.

Q: Is the Samtec TMMH-116-01-L-DV-M-TR suitable for board-to-board applications?

A: Yes. The Samtec TMMH-116-01-L-DV-M-TR is specified for Board to Board or Cable applications. It maintains the same 2-row, 32-position configuration with 0.079" (2.00mm) pitch and row spacing. The cuttable header design provides additional flexibility for custom configurations.
