Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 3-5535512-8 are identified based on strict electrical and mechanical parameter alignment. The following parameters are critical for substitution compatibility:

Critical Matching Parameters:

• Connector type: Receptacle
• Contact type: Female Socket
• Number of positions: 84
• Pitch - mating: 0.100" (2.54mm)
• Number of rows: 2
• Row spacing - mating: 0.100" (2.54mm)
• Mounting type: Through hole, right angle
• Termination: Solder
• Fastening type: Push-pull
• Contact finish - mating: Gold
• Contact finish thickness - mating: 30.0µin (0.76µm)
• Contact length - post: 0.115" (2.92mm)
• Material flammability rating: UL94 V-0
• Contact shape: Square

The Amphenol ICC (FCI) part number 66925-042 meets all critical electrical and mechanical parameters required for direct substitution. Both connectors share identical mating pitch, row configuration, contact geometry, and fastening mechanisms. Minor variations in insulation material composition and contact post finish thickness do not affect functional compatibility in standard applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: Amphenol ICC (FCI) 66925-042

The Amphenol ICC 66925-042 is the direct functional equivalent for the obsolete TE Connectivity 3-5535512-8. Both connectors share identical mating pitch, contact geometry, row configuration, and fastening mechanisms. The 66925-042 is currently in active production status, ensuring long-term supply chain availability.

Compliance Considerations:

The TE Connectivity 3-5535512-8 is ROHS3 compliant, while the Amphenol ICC 66925-042 is RoHS non-compliant. Applications subject to RoHS regulatory requirements must account for this compliance difference. The 3-5535512-8 remains the appropriate choice for RoHS-restricted applications if supply can be secured.

Material Composition Differences:

The 3-5535512-8 uses phosphor bronze contacts with polyester insulation, while the 66925-042 uses brass contacts with polyamide (nylon) insulation. Both materials meet UL94 V-0 flammability requirements and operate across the same moisture sensitivity level. Contact material differences do not affect mating compatibility or electrical performance in standard applications.

Insulation Height Variance:

The insulation height differs by 0.002" (0.05mm) between the two connectors (3-5535512-8: 0.238", 66925-042: 0.240"). This minimal variance is within typical manufacturing tolerances and does not affect mechanical fit or functional compatibility.

Inventory and Availability:

The 66925-042 is available in higher inventory quantities (1081 pcs) compared to the 3-5535512-8 (886 pcs), supporting immediate procurement for new designs and legacy system support.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol ICC 66925-042 directly replace the TE Connectivity 3-5535512-8 in existing designs?

A: Yes. Both connectors share identical mating pitch (0.100"), contact geometry (square), row configuration (2 rows), and fastening mechanism (push-pull). The 84-position receptacle configuration and through-hole right-angle mounting are identical. Direct mechanical and electrical substitution is supported.

Q: What is the significance of the RoHS compliance difference?

A: The 3-5535512-8 is ROHS3 compliant, while the 66925-042 is RoHS non-compliant. Applications subject to RoHS regulatory requirements (primarily in European markets) must use the 3-5535512-8 or identify alternative RoHS-compliant sources. Non-regulated applications may use either connector.

Q: How do the contact materials differ, and does this affect performance?

A: The 3-5535512-8 uses phosphor bronze contacts; the 66925-042 uses brass contacts. Both materials provide equivalent electrical conductivity and mating durability for standard 2A current applications. Contact material selection does not affect functional compatibility.

Q: Why is the insulation height slightly different between the two connectors?

A: The 3-5535512-8 has an insulation height of 0.238" (6.05mm), while the 66925-042 measures 0.240" (6.10mm). This 0.002" (0.05mm) difference is within standard manufacturing tolerances and does not affect mechanical fit, PCB clearance, or functional performance.

Q: What is the packaging difference between these connectors?

A: The 3-5535512-8 packaging is not specified in available documentation. The 66925-042 is supplied in tube packaging. Packaging differences do not affect connector functionality but may influence handling, storage, and procurement logistics.

Q: Are both connectors rated for the same operating temperature range?

A: The 3-5535512-8 is rated for -55°C to 125°C. The operating temperature range for the 66925-042 is not specified in available documentation. For applications requiring confirmed temperature specifications, the 3-5535512-8 documentation provides explicit thermal operating limits.

Q: What is the current rating for each connector?

A: The 3-5535512-8 is rated for 2A per contact. The current rating for the 66925-042 is not specified in available documentation. For applications requiring confirmed current specifications, the 3-5535512-8 provides explicit electrical ratings.

Q: Can these connectors be used interchangeably in new designs?

A: Yes, for applications not subject to RoHS compliance requirements. The 66925-042 is in active production status, making it the preferred choice for new designs requiring long-term supply chain support. The 3-5535512-8 is obsolete and should be reserved for legacy system maintenance where RoHS compliance is mandatory.

Q: What is the moisture sensitivity level for both connectors?

A: Both the 3-5535512-8 and 66925-042 are rated at MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard handling and storage procedures apply to both connectors.
