Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment with the following core parameters: connector type (header with male pins), pitch spacing (0.079" / 2.00mm), position count (4), row configuration (2 rows), mounting method (surface mount), termination type (solder), and flammability rating (UL94 V-0). All identified substitutes maintain these baseline requirements.

The substitute parts are grouped into two categories:

Category 1: Direct Amphenol ICC Equivalent

57202-F51-02LF: Identical electrical and mechanical specifications to the main part, with active product status and RoHS compliance upgrade.

Category 2: Samtec TMMH Series Alternatives

TMMH-102-04-F-DV, TMMH-102-04-FM-DV, TMMH-102-04-G-DV, TMMH-102-04-H-DV, TMMH-102-04-LM-DV, TMMH-102-04-S-DV, TMMH-102-04-SM-DV, TMMH-102-04-T-DV, TMMH-102-04-TM-DV: Cross-manufacturer alternatives with identical pitch, position count, row configuration, and mounting type. These parts feature cuttable header design, phosphor bronze contacts, and liquid crystal polymer insulation. Variations exist in contact finish specifications and operating temperature ranges.

Engineering Selection Recommendations

Primary Recommendation: 57202-F51-02LF

The 57202-F51-02LF is the direct equivalent from Amphenol ICC, maintaining identical electrical and mechanical specifications while offering active product status and RoHS compliance. This part is the preferred choice for designs requiring minimal qualification effort and direct form-fit-function replacement.

Secondary Recommendation: Samtec TMMH Series

The Samtec TMMH-102 series provides cross-manufacturer alternatives with equivalent pitch, position count, and row configuration. Selection within this series depends on specific contact finish and operating temperature requirements:

TMMH-102-04-F-DV and TMMH-102-04-T-DV: Bulk packaging availability with highest inventory levels (963 and 958 units respectively).
TMMH-102-04-G-DV and TMMH-102-04-H-DV: Gold-plated mating and post contacts for enhanced corrosion resistance.
TMMH-102-04-T-DV and TMMH-102-04-TM-DV: Tin-plated mating contacts with reduced operating temperature range (-55°C to 105°C versus -55°C to 125°C for gold-plated variants).

All Samtec alternatives carry ROHS3 compliance and active product status, supporting long-term supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the 57202-F51-02LF be used as a direct replacement for the obsolete 57202-F51-02?

A: Yes. The 57202-F51-02LF maintains identical pitch spacing (0.079" / 2.00mm), position count (4), row configuration (2 rows), contact type (male pin), mounting method (surface mount), and termination type (solder). The primary differences are active product status and RoHS compliance.

Q: What are the key differences between Amphenol ICC and Samtec alternatives?

A: The Amphenol ICC 57202-F51-02LF uses copper alloy contacts with thermoplastic insulation, while Samtec TMMH-102 series parts use phosphor bronze contacts with liquid crystal polymer insulation. Both maintain the required 0.079" pitch and 2-row configuration. Samtec parts feature cuttable header design, offering additional flexibility for custom configurations.

Q: Are there operating temperature limitations when substituting with Samtec parts?

A: Samtec TMMH-102 series parts with gold-plated mating contacts (TMMH-102-04-F-DV, TMMH-102-04-FM-DV, TMMH-102-04-G-DV, TMMH-102-04-H-DV, TMMH-102-04-LM-DV, TMMH-102-04-S-DV, TMMH-102-04-SM-DV) operate from -55°C to 125°C. Parts with tin-plated mating contacts (TMMH-102-04-T-DV, TMMH-102-04-TM-DV) operate from -55°C to 105°C. Verify application temperature requirements before selection.

Q: Do all substitute parts meet the same flammability and compliance standards?

A: Yes. All identified substitutes carry UL94 V-0 material flammability rating and ROHS3 compliance status. The main part (57202-F51-02) is RoHS non-compliant, making the 57202-F51-02LF or Samtec alternatives necessary for new designs subject to RoHS requirements.

Q: What packaging options are available for production quantities?

A: The 57202-F51-02LF is available in box packaging. Samtec TMMH-102-04-F-DV and TMMH-102-04-T-DV are available in bulk packaging. Other Samtec variants are available without specified packaging designation. Confirm packaging requirements with supplier for production planning.

Q: Are the contact finish specifications interchangeable?

A: Contact finish specifications differ across the substitute range. The main part and 57202-F51-02LF feature gold-plated mating contacts with flash thickness. Samtec variants offer multiple finish options including gold (various thicknesses) and tin plating. Contact finish selection affects corrosion resistance and mating force characteristics; verify compatibility with mating connector specifications.
