Key Parameters

Substitute Part Grouping Explanation

Substitution of the Molex 0877584477 is determined by strict alignment of the following critical parameters:

• Connector geometry: 44 positions, 2 rows, 0.079" (2.00mm) pitch and row spacing
• Contact configuration: Male pin, gold-plated mating surface, tin-plated post
• Mounting and termination: Through-hole solder termination with push-pull fastening
• Electrical and mechanical compatibility: Board-to-board or cable style, unshrouded design
• Regulatory compliance: UL94 V-0 flammability rating, RoHS compliance, MSL 1

The Amphenol ICC (FCI) part number 57102-G06-22LF meets all these critical parameters and qualifies as a direct substitute. Both connectors share identical pitch, position count, row configuration, contact type, mounting method, and regulatory certifications.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0877584477 and Amphenol ICC 57102-G06-22LF are active products with equivalent regulatory compliance. Selection between these parts should be based on the following factors:

Molex 0877584477 is suitable when the original design specification requires the Milli-Grid 87758 series characteristics, including the specific polyamide insulation material and contact post length of 0.102" (2.60mm).

Amphenol ICC 57102-G06-22LF is suitable as a substitute when supply constraints affect the Molex part. This connector offers enhanced gold plating thickness (30.0µin versus 15.0µin) on mating contacts, which may provide improved contact durability. The thermoplastic insulation material and slightly shorter contact post (0.098" versus 0.102") represent minor dimensional variations within acceptable tolerance ranges for board-to-board applications. Both parts maintain identical pitch, position count, row spacing, and fastening characteristics.

Both connectors carry active product status, RoHS compliance, and UL94 V-0 flammability certification, confirming suitability for automotive, general purpose, and telecommunications applications.

Frequently Asked Questions (FAQ)

Q: What are the critical parameters that determine if a connector can substitute for the Molex 0877584477?

A: The critical parameters are: 44-position count, 2-row configuration, 0.079" (2.00mm) mating pitch and row spacing, male pin contact type, gold-plated mating surface, tin-plated post, through-hole solder termination, push-pull fastening, and unshrouded design. Any deviation in these parameters disqualifies a connector as a direct substitute.

Q: Are there dimensional differences between the Molex and Amphenol ICC connectors?

A: Minor dimensional variations exist in contact post length (0.102" for Molex versus 0.098" for Amphenol ICC) and overall contact length (0.319" versus 0.315"). These differences are within acceptable mechanical tolerances for board-to-board applications and do not affect electrical or functional compatibility.

Q: Does the Amphenol ICC part have better contact plating than the Molex part?

A: The Amphenol ICC 57102-G06-22LF features thicker gold plating on mating contacts (30.0µin versus 15.0µm), which may provide enhanced contact durability and resistance to wear in high-cycle mating applications.

Q: What is the difference between the insulation materials used in these connectors?

A: The Molex 0877584477 uses polyamide (PA) nylon with glass filling, while the Amphenol ICC 57102-G06-22LF uses thermoplastic insulation. Both materials meet UL94 V-0 flammability requirements and are suitable for the specified applications.

Q: Are both connectors RoHS compliant?

A: Yes. The Molex 0877584477 is ROHS3 compliant, and the Amphenol ICC 57102-G06-22LF is RoHS compliant. Both meet regulatory requirements for restricted substance elimination.

Q: What is the packaging difference between these parts?

A: The Molex 0877584477 is supplied in tray packaging, while the Amphenol ICC 57102-G06-22LF is supplied in bulk packaging. Packaging format does not affect connector functionality or compatibility.

Q: Can the Amphenol ICC connector be used in automotive applications?

A: The Amphenol ICC 57102-G06-22LF is suitable for general purpose applications. Automotive suitability should be confirmed against specific application requirements and automotive qualification standards applicable to your design.
