Parameter Comparison

Engineering Selection Recommendations

Both the Amphenol ICC 66953-004 and TE Connectivity AMP Connectors 534206-4 are active production parts with identical mechanical interfaces and mating characteristics. Selection between these parts should be based on:

Availability: The 534206-4 has higher inventory availability (2519 units) compared to the 66953-004 (1035 units), making it suitable for high-volume procurement scenarios.

Compliance Status: Both parts carry identical RoHS non-compliant and REACH-affected designations, with matching moisture sensitivity levels (MSL 1 - Unlimited). No compliance advantage exists between the two options.

Electrical Specifications: The 66953-004 specifies a 1250V voltage rating, while the 534206-4 specifies a 2A current rating. Application requirements must determine which electrical parameter is critical for your design.

Physical Dimensions: Minor variations exist in insulation height (0.325" vs 0.320") and contact post length (0.138" vs 0.115"). These differences are within typical manufacturing tolerances for board-to-board connector applications but should be verified against PCB layout constraints.

Contact Material Composition: The 66953-004 uses brass contacts with tin plating, while the 534206-4 uses phosphor bronze contacts with tin-lead plating. Both material systems are suitable for general-purpose, industrial, medical, and telecommunications applications.

Frequently Asked Questions (FAQ)

Q: Can the 534206-4 directly replace the 66953-004 in existing designs?

A: Yes, the 534206-4 is mechanically and electrically compatible for direct substitution. Both connectors share identical mating pitch (0.100"), row configuration (2 rows), position count (8), fastening type (push-pull), and termination method (solder). PCB layout compatibility should be verified due to minor dimensional variations in insulation height and contact post length.

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

A: The primary differences are contact material composition (brass vs phosphor bronze), contact post finish (tin vs tin-lead), and specified electrical ratings (1250V vs 2A). Both connectors maintain identical mechanical interfaces and operating temperature ranges (-65°C ~ 125°C).

Q: Are there any compliance or certification differences?

A: Both parts share identical compliance profiles: RoHS non-compliant, REACH-affected, MSL 1 (Unlimited), and matching ECCN/HTSUS classifications. No compliance advantage exists between the two options.

Q: What should I verify before substituting these parts?

A: Verify that your PCB layout accommodates the dimensional variations in insulation height (0.325" vs 0.320") and contact post length (0.138" vs 0.115"). Confirm that your application's electrical requirements align with the specified voltage (1250V) or current (2A) ratings. Validate mating connector compatibility with the push-pull fastening mechanism.

Q: Which part should I select for new designs?

A: Selection depends on application-specific requirements. If voltage rating is critical, use the 66953-004 (1250V specified). If current capacity is the limiting factor, use the 534206-4 (2A specified). For general-purpose applications where both ratings are adequate, the 534206-4 offers superior inventory availability.

Q: Are these connectors suitable for automotive and medical applications?

A: Yes, both connectors are listed for automotive, general purpose, industrial, medical, and telecommunications applications. Application-specific qualification and testing requirements should be determined by your design and quality assurance processes.
