57102-F08-04ULF Equivalent & Substitute Parts

Part Overview

The 57102-F08-04ULF is an 8-position, 2-row rectangular connector header manufactured by Amphenol ICC (FCI) under the Minitek® 2.00mm series. This through-hole board-to-board connector features male pins with 0.079" (2.00mm) pitch spacing and is designed for applications requiring reliable push-pull fastening with solder termination. The part is currently active in production with 750 units in stock. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design flexibility permits component interchange based on equivalent electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 57102-F08-04ULF is determined by the following critical parameters:

• Connector Type & Style: Header, board-to-board configuration
• Contact Configuration: Male pin, 8 positions, 2 rows
• Pitch Specification: 0.079" (2.00mm) mating pitch and row spacing
• Mounting & Termination: Through-hole solder termination with push-pull fastening
• Electrical Performance: Current and voltage ratings must meet or exceed the original specification
• Compliance: RoHS and material flammability ratings (UL94 V-0)

The substitute part MTMM-104-02-G-D-150 from Samtec Inc. satisfies these core substitution criteria. Both parts share identical connector type, contact configuration, pitch spacing, mounting method, and termination approach. Both are active products with RoHS compliance and UL94 V-0 flammability rating.

Parameter Comparison

Engineering Selection Recommendations

Both the 57102-F08-04ULF and MTMM-104-02-G-D-150 are active products with equivalent core connector specifications. Selection between these parts should be based on the following engineering considerations:

Electrical Performance: The MTMM-104-02-G-D-150 provides a higher current rating of 3A compared to the 2A rating of the 57102-F08-04ULF. For applications operating at or below 2A, both parts are functionally equivalent. For applications requiring current capacity between 2A and 3A, the Samtec part provides additional margin.

Temperature Operating Range: The MTMM-104-02-G-D-150 specifies an operating temperature range of -55°C to 125°C. The 57102-F08-04ULF does not provide an operating temperature specification. Applications with defined temperature requirements should reference the Samtec part's published range.

Insulation Material: The 57102-F08-04ULF uses thermoplastic insulation, while the MTMM-104-02-G-D-150 uses Liquid Crystal Polymer (LCP). Both materials meet UL94 V-0 flammability requirements. LCP provides enhanced dimensional stability and chemical resistance.

Connector Flexibility: The MTMM-104-02-G-D-150 is specified as cuttable and supports both board-to-board and cable configurations, providing greater design flexibility than the board-to-board only specification of the 57102-F08-04ULF.

Compliance: Both parts are RoHS compliant and meet UL94 V-0 flammability standards. The Samtec part carries ROHS3 compliance designation.

Packaging & Availability: The 57102-F08-04ULF is supplied in tube packaging with 750 units in stock. The MTMM-104-02-G-D-150 is supplied in bulk packaging with 1077 units in stock.

Frequently Asked Questions (FAQ)

Q: Can the MTMM-104-02-G-D-150 directly replace the 57102-F08-04ULF in existing designs?

A: Yes, for applications operating within the 57102-F08-04ULF specifications. Both connectors share identical pitch spacing (0.079" / 2.00mm), position count (8 positions, 2 rows), mounting type (through-hole), termination method (solder), and fastening mechanism (push-pull). The mating interface and PCB footprint are compatible.

Q: What are the key differences between these two parts?

A: The primary differences are: (1) Current rating: MTMM-104-02-G-D-150 is rated for 3A versus 2A for the 57102-F08-04ULF; (2) Insulation material: LCP versus thermoplastic; (3) Operating temperature range: -55°C to 125°C specified for the Samtec part; (4) Connector flexibility: the Samtec part supports both board-to-board and cable configurations; (5) Packaging: tube versus bulk.

Q: Are there any mechanical compatibility concerns?

A: Contact length specifications differ between the parts. The 57102-F08-04ULF has an overall contact length of 0.335" (8.51mm), while the MTMM-104-02-G-D-150 has 0.255" (6.48mm). Verify that mating connector receptacles accommodate these dimensional variations. The mating contact length is 0.157" (4.00mm) for the Amphenol part and 0.150" (3.81mm) for the Samtec part, representing a 0.007" difference.

Q: Which part should be selected for new designs?

A: Selection depends on application requirements. For applications requiring higher current capacity, wider operating temperature range, or greater connector flexibility, the MTMM-104-02-G-D-150 is the preferred choice. For applications with existing inventory or specific design constraints tied to the Amphenol part, the 57102-F08-04ULF remains a valid selection within its rated specifications.

Q: Are both parts RoHS compliant?

A: Yes. The 57102-F08-04ULF is RoHS Compliant. The MTMM-104-02-G-D-150 is ROHS3 Compliant. Both meet RoHS requirements for restricted substance elimination.

Q: What is the significance of the cuttable feature on the Samtec part?

A: The cuttable feature on the MTMM-104-02-G-D-150 allows the connector to be segmented to custom position counts during assembly, providing design flexibility. The 57102-F08-04ULF is a fixed 8-position configuration.
