Engineering Selection Recommendations

All listed substitute parts are classified as Active products with current manufacturing status, ensuring long-term supply chain availability compared to the obsolete 951216-2520-AR-TP.

Amphenol ICC Minitek® 2.00mm Series (57202 Base): These parts provide direct functional equivalence with enhanced current ratings (2A vs. 1A) and defined voltage specifications (200V AC/DC). The 57202-F52-08LF, 57202-G52-08LF, 57202-G52-08ULF, 57202-S52-08LF, and 57202-S52-08ULF variants differ primarily in packaging format and contact finish thickness. RoHS compliance is confirmed for all variants. The GXT™ contact finish variants (G and S series) provide enhanced durability compared to standard flash plating.

Amphenol ICC 91753-015TRLF: This variant offers Tape & Reel packaging with board guide and pick-and-place features, suitable for automated assembly environments. Natural insulation color differs from the original black specification. RoHS compliance confirmed.

Sullins NRPN082MAMP-RC: This part provides equivalent functionality with brass contact material and flash gold post finish. Operating temperature range extends to -40°C, exceeding the original specification. ROHS3 compliance confirmed with REACH Unaffected status.

Samtec TMM Series (TMM-108-01-S-D-SM-A and TMM-108-01-S-D-SM-A-P-TR): These parts deliver superior current capacity (3.2A per contact) and extended operating temperature range (-55°C to 125°C). Phosphor bronze contact material and liquid crystal polymer insulation provide enhanced performance characteristics. ROHS3 compliance and REACH Unaffected status confirmed. The -P-TR variant includes Tape & Reel packaging with pick-and-place features.

Samtec TMMH-108-01-L-DV-A: This low-profile cuttable header variant offers flexibility for custom configurations. Insulation height of 0.079" (2.00mm) matches row spacing. ROHS3 compliance confirmed. Current and voltage ratings are not specified for this variant.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with a higher current rating than the original 951216-2520-AR-TP?

A: Yes. Substitute parts rated at 2A or 3.2A per contact exceed the original 1A specification and are fully compatible. Higher current ratings provide design margin and do not compromise functionality in applications requiring 1A or less.

Q: What is the difference between the various Amphenol ICC 57202 variants?

A: The 57202 series variants differ in packaging format (Box, Bulk, Tube, or Tape & Reel) and contact finish thickness. The F52 variant uses standard flash plating. The G52 and S52 variants use GXT™ enhanced gold plating with different thickness specifications (30.0µin and 15.0µin respectively). All variants maintain identical electrical and mechanical specifications for 16-position, 2.00mm pitch headers.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts carry RoHS compliance certifications (RoHS Compliant or ROHS3 Compliant). The original 951216-2520-AR-TP does not specify RoHS status due to its obsolete classification.

Q: What is the significance of the GXT™ contact finish on Amphenol ICC parts?

A: GXT™ is an enhanced gold plating technology that provides improved durability and corrosion resistance compared to standard flash plating. This is particularly beneficial for connectors subject to repeated mating cycles or harsh environmental conditions.

Q: Can I use the Samtec TMMH-108-01-L-DV-A cuttable header as a direct replacement?

A: The TMMH-108-01-L-DV-A is functionally compatible for board-to-board applications with identical pitch and position count. However, it is classified as a cuttable header, allowing custom configuration. Current and voltage ratings are not specified for this variant, so application requirements should be evaluated independently.

Q: What packaging options are available for high-volume production?

A: Tape & Reel packaging is available for automated assembly: 91753-015TRLF (Amphenol ICC) and TMM-108-01-S-D-SM-A-P-TR (Samtec). Both variants include board guide and pick-and-place features optimized for surface mount assembly equipment.

Q: How do the Samtec TMM series parts compare to Amphenol ICC parts?

A: Samtec TMM series parts deliver higher current capacity (3.2A per contact vs. 2A) and wider operating temperature range (-55°C to 125°C vs. standard specifications). Phosphor bronze contact material and liquid crystal polymer insulation provide enhanced performance. These parts are suitable for demanding applications requiring superior electrical and thermal characteristics.

Q: Is the contact material difference between copper alloy and phosphor bronze significant?

A: Both materials are acceptable for this connector category. Phosphor bronze (used in Samtec parts) offers enhanced spring properties and durability under repeated mating cycles. Copper alloy (used in Amphenol ICC and Sullins parts) provides standard performance characteristics. Material selection should be based on application cycle life requirements.

Q: What is the difference between board-to-board and board-to-board or cable style?

A: Board-to-board style is optimized for connector-to-connector mating on PCBs. Board-to-board or cable style provides flexibility for both PCB-to-PCB and cable harness applications. All substitute parts support at least board-to-board functionality; several variants support both configurations.
