Key Parameters

Substitute Part Grouping Explanation

The Amphenol ICC 66953-016LF qualifies as a direct substitute for the 66952-016LF based on the following critical parameters:

Matching Parameters (Substitution Basis):

• Connector type: Receptacle
• Number of positions: 32
• Pitch - mating: 0.100" (2.54mm)
• Number of rows: 2
• Row spacing - mating: 0.100" (2.54mm)
• Mounting type: Through hole
• Termination: Solder
• Contact type: Female socket
• Fastening type: Push-pull
• Insulation material: Polyester, glass filled
• Insulation color: Black
• RoHS compliance: Yes

These parameters define the mechanical and electrical interface compatibility required for board-to-board connectivity in standard 0.100" pitch applications.

Parameter Comparison

Engineering Selection Recommendations

The 66953-016LF is the appropriate substitute for the obsolete 66952-016LF. Both connectors maintain identical mechanical and electrical interface specifications for 32-position, 0.100" pitch board-to-board applications.

The 66953-016LF offers the following advantages:

• Active product status with current manufacturing support and availability
• RoHS compliance maintained
• Enhanced mating contact finish thickness (30.0µin vs. 15.0µin) providing improved durability
• Specified operating temperature range (-65°C ~ 125°C) and voltage rating (1250V)
• Tin-plated post contacts with defined finish thickness
• Tube packaging for standard component handling

Both parts share identical pitch, row configuration, mounting method, and termination approach, ensuring direct mechanical and electrical compatibility in existing board designs.

Frequently Asked Questions (FAQ)

Q: Can the 66953-016LF directly replace the 66952-016LF in existing designs?

A: Yes. Both connectors share identical pitch (0.100"), position count (32), row configuration (2 rows), mounting type (through hole), and termination method (solder). The mechanical and electrical interfaces are compatible.

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

A: The primary differences are product status (66952-016LF is obsolete; 66953-016LF is active), mating contact finish thickness (15.0µin vs. 30.0µin), contact post length (0.142" vs. 0.138"), and the availability of specified operating temperature and voltage ratings on the 66953-016LF.

Q: Are there any compatibility concerns with the contact post length difference?

A: The contact post length difference (0.142" vs. 0.138") is 0.004" (0.10mm). This minor variation falls within standard PCB through-hole tolerance ranges and does not affect functional compatibility.

Q: Does the 66953-016LF meet the same compliance standards?

A: Yes. Both parts are RoHS compliant, carry the same ECCN (EAR99) and HTSUS classifications, and share identical moisture sensitivity levels (MSL 1).

Q: What packaging is available for the 66953-016LF?

A: The 66953-016LF is supplied in tube packaging, suitable for standard component handling and automated assembly processes.

Q: Are both parts suitable for automotive and industrial applications?

A: The 66953-016LF is specified for automotive, general purpose, industrial, medical, and telecommunications applications. The 66952-016LF does not list specific applications in the provided data.
