Amphenol ICC 66951-012 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 66951-012 is a 12-position receptacle connector with 0.100" (2.54mm) pitch, designed for through-hole PCB mounting with solder termination. This connector features gold-plated mating contacts and is part of the Dubox™ and BergCon® PV™ series. The product is currently active and widely used in automotive, industrial, medical, and telecommunications applications. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design flexibility permits equivalent component selection.

Substitute Part Grouping Explanation

Substitution eligibility for the Amphenol ICC 66951-012 is determined by the following critical parameters:

Connector Type & Contact Configuration: Must be a receptacle with female socket contacts
Position Count & Pitch: Must maintain 12 positions at 0.100" (2.54mm) mating pitch
Mounting & Termination: Must support through-hole PCB mounting with solder termination
Mating Contact Finish: Must feature gold-plated mating contacts
Operating Temperature: Must support -65°C to 125°C range
Insulation Material: Must use polyester with glass reinforcement
Contact Shape & Material: Must use square-shaped contacts with brass or equivalent phosphor bronze construction
Fastening Mechanism: Must employ push-pull fastening

The substitute part TE Connectivity AMP Connectors 1-534237-0 meets all critical substitution criteria within these parameters.

Engineering Selection Recommendations

Both the Amphenol ICC 66951-012 and TE Connectivity 1-534237-0 are active products with identical RoHS non-compliance status and REACH-affected classification. Selection between these parts should be based on:

Amphenol ICC 66951-012: Primary choice when brass contact material and tin post finish are specified in design documentation. Current inventory of 1016 units supports immediate availability.

TE Connectivity 1-534237-0: Suitable alternative when phosphor bronze contact material and tin-lead post finish are acceptable. The increased post finish thickness (150.0µin vs. 100.0µin) provides enhanced durability in high-cycle mating applications. Current inventory of 933 units available.

Both connectors maintain identical electrical and thermal performance within the specified operating range and are mechanically compatible for board-to-board applications with push-pull fastening.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1-534237-0 be used as a direct replacement for the Amphenol ICC 66951-012?

A: Yes. Both connectors share identical pitch (0.100"), position count (12), mounting type (through-hole), and mating contact finish (gold). Mechanical and electrical compatibility is confirmed across all critical parameters.

Q: What are the differences in contact materials between these two connectors?

A: The Amphenol ICC 66951-012 uses brass contacts with tin plating, while the TE Connectivity 1-534237-0 uses phosphor bronze contacts with tin-lead plating. Both materials provide equivalent electrical performance and are suitable for the specified operating temperature range.

Q: Are there dimensional differences that affect PCB layout?

A: Minor differences exist in insulation height (0.325" vs. 0.340") and contact post length (0.142" vs. 0.115"). These variations do not affect mating compatibility but should be verified against specific PCB design requirements for clearance and stacking height considerations.

Q: Do both connectors meet the same compliance standards?

A: Both connectors share identical RoHS non-compliance status and REACH-affected classification. Compliance verification should be performed against specific application requirements and regional regulations.

Q: What is the current rating for these connectors?

A: The Amphenol ICC 66951-012 does not specify a current rating in available documentation. The TE Connectivity 1-534237-0 is rated for 2A per contact. Application-specific current requirements should be verified against actual load conditions.
